Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.Children are considered to be overweight if the BMI (Body Mass Index) is over 85% of the weight group in their age and sex categories. If it is 95% and over, they are considered to be obese. Adolescents are generally judged according to adult criteria for obesity, although there are other considerations in this population. Ethnic variations, timing of growth spurts, and higher normal fat levels around puberty can cause disparities in these measurements.Causes and Risk Factors for Obesity in ChildrenLifestyle Factors. Without educational or parental guidance, children are extremely vulnerable to the intense cultural pressures that are largely responsible for the obesity epidemic. Neither the media nor the educational system has strong well-financed programs that encourage healthy-alternatives, including exercise and healthy foods. The following are some specific problems created by the culture:* Excessive television watching plays a critical role in obesity in children. Not only is it a sedentary activity, but television also offers innumerable temptations with its advertisements for fast foods, sugar cereals, and unhealthy snacks. In one study obesity rates were lowest in children who watched television one hour or less a day and highest in those who watched four or more hours.* Sugar, particularly from soda, other sweetened beverages, and fruit juice, may be major contributors to childhood obesity. One study reported that drinking soda regularly increases a child’s risk for obesity by 60%.* Less physical exercise and greater sedentary activities play another significant role in obesity in children. A high level of physical, activity—not just using up energy—is important for weight control in young people.Family History. Parental obesity more than doubles the risk that a young child, whether thin or overweight, will become obese as an adult. In older children and teenagers, obesity in parents starts to count less as a predictor for body weight than their own weight. The risk may be due to environmental or genetic factors, or both.Ethnic and Socioeconomic Factors. As in adult populations, children from lower socioeconomic groups and minority populations are at higher risk for obesity. For example, among young Mexican Americans and African Americans, there has been an increase in overweight prevalence of about 13% to over 23%.Factors Surrounding Birth. The following factors surrounding birth are associated with a child’s weight:* Low birth weight is a risk factor for later obesity and diabetes. One theory is that humans have a “th rifty gene” that produces metabolic changes in infants with low birth weight. Such changes affect insulin and fat accumulation in order to produce a “catch-up” weight in these young children as quickly as possible. This rapid weight gain i n infancy increases the gain risk for obesity in children and also in young adulthood.* In a study of African American children, having an overweight pregnant mother increased the risk for later weight gain, but low birth weight did not.Although some small studies have reported protection against obesity from breastfeeding, evidence is weak. In a 2003 study, for example, children who were breast fed for three to five months had a lower risk for obesity, but prolonged breastfeeding had noeffect. Nevertheless, given the healthful effects of breast feeding and the possibility that it may have even a slight impact on childhood obesity, it is highly recommended.Health Consequences of Childhood ObesityChildren and adolescents who are obese have poorer health than other children. Studies are reporting unhealthy cholesterol levels and high blood pressure in obese children and adolescents. Of great concern is the dramatic increase in type 2 diabetes in young people, which is most certainly largely due to the increase in obesity. Obesity in children is also linked to asthma, gallbladder problems, sleep apnea, and liver abnormalities. Childhood obesity may be partly responsible for the declining age for onset of puberty in girls, with subsequent risks for breast cancer.It is not clear yet how many of these childhood problems persist in people who achieve normal weight as adults. Staying overweight into adulthood certainly confers health risks.Managing Overweight and Obese ChildrenChildhood obesity is best treated by a non-drug, multidisciplinary approach including diet, behavior modification, and exercise. Some evidence suggests that reducing calories by only 200 to 260 per day would prevent weight gain in most overweight children. Here some tips for children who are overweight:* Limit or avoid if possible take-out, fast foods, high-sugar snacks, commercial packaged snacks, soda and sugar sweetened beverages (including too much juice).* Let children snack but make sure the snacks are healthy. Eating small frequent healthy meals (instead of two or three large ones) has been associated with being thinner and having a better cholesterol profile.* Let children choose their own food portions. One study indicated that children naturally ate 25% less than they chose their own portion size. When they were given larger portions their bite sizes were larger and they ate more.* Don’t criticize a child for being overweight. It does not help and such attitudes could put children at risk for eating disorders, which are equal or even greater dangers to health.* Limit television, video games, and computer use to a few hours a week. This can contribute significantly to weight control, regardless of diet and physical activity.* For young children, try the traffic-light diet. Food is designated with stoplight colors depending on their high caloric content: Green for go (low calories); yellow for “eat with caution” (medium calories); red for “stop” (high calories).* Try a low-glycolic index diet. This may be as beneficial and possibly more than a standard reduced-fat diet in obese children. Such a diet focuses on carbohydrates, such asdried beans and soy, that raise blood sugar more slowly than others. This diet is sometimes used in diabetes and as a dietary approach in overweight adults.1. Overweight children are those whose BMI is over 85% of the weight group in their age and sex categories.2. The educational system is positive in promoting exercise and healthy foods, according to the passage.3. It is observed that children watching television one hour or less a day tend to be less likely to suffer from obesity.4. The intake of sugar among children is an important contributor to childhood obesity.5. In most cases, obese children tend to have parents suffering obesity, as environmental or genetic factors are the major reasons for childhood obesity.6. Infants with low birth weight may face a risk for obesity as they grow up into childhood and young adulthood.7. For obese children, achieving a healthy weight becomes more difficult as they get older, as the persistence is biological.8. Obese children and adolescents have poorer health, as they are reported to have unhealthy .9. It is suggested that reducing calories would prevent weight gain in most overweight children.10. The author believes that it does not help to criticize children for being overweight, as this may increase the risk for.Part ⅢListening Comprehension(35 minutes)Section ADirections: In this section, you will hear 8 short conversations and 2 long conversations.

That was when there were 50 in plenty and the fields were the traditional“fields of the woods” —clearings in the forest—and therefore always tree 51 .It is the trees that lift the water and send 52 into the air so that it may fall as dew or rain further on. Trees reduce the speed of the wind, and provide shelter and shade; the roots 53 minerals in the soil and these are carried to the leaves which, when they have fulfilled their function, return to the earth, giving the soil the combination of minerals that plants require.But through the ages Africa has been 54 . Successive invaders have felled the forest to provide grazing lands for their flocks and herds.

You should decide on the best choice and mark the corresponding letter on the Answer Sheet 2 with a single line through the centre.Passage OneQuestions 57 to 61 are based on the following passage.No one knows when the first calendar was developed. But it seems possible that it was based on lunar months. When people started farming, the sages of the tribes became very important, they studied the sky and gathered enough information to be able to predict when the seasons would change, and were able to announce when it was time to plant crops.The divisions of time we use today were developed in ancient Babylonia 4,000 years ago.Babylonian astronomers believed the sun moved around the Earth every 365 days.They divided the trip into 12 equal parts, each with 30 days. Then they divided each day into 24 equal parts, or hours, and divided each hour into 60 minutes, each minute into 60 seconds.Humans have used many devices to measure time; the sundial (日晷) was one of the earliest and simplest. However, the sundial worked well only when the weather was fine, so other ways of measuring the passing of time were invented. One device was the hourglass(沙漏). By the eighteenth century, people had developed mechanical clocks and watches. So we have devices to mark the passing of time, but what time is it now? Clocks in different parts of the world do not show the same time at the same time, because time on Earth is set by th e sun’s positions in the sky above us. As international communications and travel grew, it became clear that a way to establish a common time for all parts of the world was needed. In 1884, an international conference divided the world into 24 time zones, each zone represents one hour. The astronomical observatory in Greenwich, England, was chosen as the starting point for the time zones. Twelve zones are west of Greenwich. Twelve are east. The time at Greenwich measured by the sun is considered by astronomers to be Universal Time, also known as Greenwich Mean Time.57. Which of the following is the best title for this passage?A) The Development of Universal Time.B) Different Ways to Measure Time.C) Why We Measure Time the Way We do.D) How the Calendar Came into being.58. What does the example of Babylonia astronomers reveal?A) It reveals Babylonian s’wisdom that was absent elsewhere.B) It reveals the origin of our time measurements.C) It reveals the limits of sometime measurements.D) It reveals the stability of time measurements.59. The author mentions all of the following ways to measure time EXCEPT .A) sundial B) hourglass C) electric clock D) mechanical clock60. According to the passage, Greenwich Mean Time .A) provides a common time for all parts of the worldB) is calculated from the sunC) is the 12th of the 24 time zonesD) was named after an international conference61. With which of the following statements would the author be most likely to agree?A) Time measurements have changed in response to need and technological development.B) In ancient Babylonia, 12 was the basic division of time.C) The first calendar was developed because the sages of tribes were intelligent.D) Universal Time is so named because it is applicable throughout the universe.Passage TwoQuestions 62 to 66 are based on the following passage.For many years, scientists couldn’t figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocea n. What’s more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions ofhydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids—the very kind of molecules found in all living things.62. When did scientists come to realize how the atoms and molecules on the Earth combined to make living thing?A) 4 billion years ago. B) In 1953.C) After seven days. D) Many years later.63. Scientists figured out that human bodies are basically made of .A) amino acidsB) moleculesC) hydrogen, carbon, nitrogen and oxygen atomsD) water vapor, ammonia, carbon dioxide, methane and hydrogen64. Harold Urey and Stanley ler did their experiment in order to .A) find out what had happened on the Earth 4 billion years agoB) simulate bolts of lightning on the ancient EarthC) dissolve some new chemicalsD) analyze a liquid65. At the end of the last paragraph, the word “it” refers to .A) a closed loop B) an electric spark C) water D) the liquid66. According to the writer, living things on the Earth include .A) atoms and molecules B) chemicalsPart ⅤCloze(15 minutes)Directions:There are 20 blanks in the following passage.

Some have sufficient faith that the paid holidays will improve the current tourism pattern. The new holiday scheme will give people more choices to make their holiday plans and thus it will greatly alleviate the pressure of transportation departments, security bodies, shopping malls, ect. during the current holiday boom.Other people wonder if the new system will be available. It is likely to be a dream to have a paid holiday. Because the problem is that many people don’t dare to take long vacations. Competition is fierce. Nobody can afford a long holiday and leave the boss with an impression of not working as hard as others.For me, I think it is necessary for, in future, the state to issue a regulation concerning Chinese workers-paid holidays. Stregthen the employers’ sense of the paid holidays. If they did so voluntarily, it will attract and retain employees. With these measures, it is expected that more employees in China are entitled to receive holiday pay for time off.Part ⅡReading Comprehension (Skimming and Scanning)1. Y 细节题根据信号词“BMI, 85%”寻读到第二段第一句。

Currently over 15% of young people over 6 years old are obese, and obesity is also increasing among children aged 5 and younger.Mass Index) is over 85% of Children are considered to be overweight if the BMI (Bodythe weight group in their age and sex categories.

For example, among young Mexican Americans and African Americans, there has been an increase in overweight prevalence of about 13% to over 23%.Factors Surrounding Birth. The following factors surrounding birth are associated with a child’s weight:factor for later obesity and diabetes. One theory is that * Low birth weight is a risk f actorhumans have a “th rifty gene” that produces metabolic changes in infants with low birth weight. Such changes affect insulin and fat accumulation in order to p roduceproduce an “catch-up” weight in these young children as quickly as possible. This rapid weight gain i infancy increases the gain risk for obesity in children and also in young adulthood.* In a study of African American children, having an overweight pregnant mother increased the risk for later weight gain, but low birth weight did not.Although some small studies have reported protection against obesity from breastfeeding, evidence is weak. In a 2003 study, for example, children who were breast fed for three to five months had a lower risk for obesity, but prolonged breastfeeding had noeffect. Nevertheless, given the healthful effects of breast feeding and the possibility that it slight impact on childhood obesity, it is highly recommended.may have even a s lightHealth Consequences of Childhood ObesityChildren and adolescents who are obese have poorer health than other children. Studies are reporting unhealthy cholesterol levels and high blood pressure in obese children anddramatic increase in type 2 diabetes in young people, adolescents. Of great concern is the d ramaticwhich is most certainly largely due to the increase in obesity. Obesity in children is also linked to asthma, gallbladder problems, sleep apnea, and liver abnormalities. Childhood obesity may be partly responsible for the declining age for o nsetonset of puberty in girls, with subsequent risks for breast cancer.achievepersist in people who a chieve It is not clear yet how many of these childhood problemsnormal weight as adults. Staying overweight into adulthood certainly confers health risks.Managing Overweight and Obese ChildrenChildhood obesity is best treated by a non-drug, multidisciplinary approach includingevidence suggests that reducing calories diet, behavior modification, and exercise. Some e videnceby only 200 to 260 per day would prevent weight gain in most overweight children. Here some tips for children who are overweight:* Limit or avoid if possible take-out, fast foods, high-sugar snacks, commercial packaged snacks, soda and sugar sweetened beverages (including too much juice).frequent * Let children snack but make sure the snacks are healthy. Eating smallhealthy meals (instead of two or three large ones) has been associated with being thinner and having a better cholesterol profile.* Let children choose their own food portions. One study indicated that children naturally ate 25% less than they chose their own portion size. When they were given larger portions their bite sizes were larger and they ate more.* Don’t criticize a child for being overweight. It does not help and such attitudes could put children at risk for eating disorders, which are equal or even greater dangers to health.* Limit television, video games, and computer use to a few hours a week. This can contribute significantly to weight control, regardless of diet and physical activity.* For young children, try the traffic-light diet. Food is designated with stoplight colorscontent: Green for go (low calories); yellow for “eat with depending on their high caloric c ontentcaution” (medium calories); red for “stop” (high calories).* Try a low-glycolic index diet. This may be as beneficial and possibly more than a standard reduced-fat diet in obese children. Such a diet focuses on carbohydrates, such asdried beans and soy, that raise blood sugar more slowly than others. This diet is sometimes used in diabetes and as a dietary approach in overweight adults.weight group in their age1. Overweight children are those whose BMI is over 85% of theand sex categories.2.

Then they divided each day into 24 equal parts, or hours, and divided each hour into 60 minutes, each minute into 60 seconds.日晷) was one of the Humans have used many devices to measure time; the sundial (日晷earliest and simplest. However, the sundial worked well only when the weather was fine, so other ways of measuring the passing of time were invented. One device was thehourglass(沙漏). By the eighteenth century, people had developed mechanical clocks and watches. So we have devices to mark the passing of time, but what time is it now? Clocks in different parts of the world do not show the same time at the same time, because time on Earth is set by th e sun’s positions in the sky above us. As international communications and travel grew, it became clear that a way to establish a common time for all parts of the world was needed. In 1884, an international conference divided the world into 24 time zones,astronomical observatory in Greenwich, England, each zone represents one hour. The a stronomicalwas chosen as the starting point for the time zones. Twelve zones are west of Greenwich. Twelve are east.

In my opinion, square dance has exceptional advantages of enriching senior citizens’ lives.First of all, there is no doubt that Dama square dance can play an important role in improving the elderly’s health. Doing square dance may help cure some chronic diseases, thus lowering the costs of health care for the elderly. Secondly, this group activity has a social function for the lonely and helpless senior citizens, especially those from other cities. It offers a golden opportunity to make friends and communicate with one another. Finally, Damas do not need to spend any money on square dance.In order to avoid disturbing people in the neighborhood, we should impose some restrictions on the “timing” and “music volume” of square dance. For instance, square dance should finish before 7 ., and music volume should be turned down to such an extent so as not to affect other people’s life.Government should also draft relevant regulations as soon as possible.Part II Listening Comprehension1.

You should write at least 150 words but no more than 200 words.Online Learning: Advantages and DisadvantagesOnline learning, also known as e-learning or distance education, has gained increasing popularity in recent years. It provides students with the flexibility to study at their own pace and convenience. However, it also brings some disadvantages.One of the advantages of online learning is the flexibility it offers. Students can access course materials and lectures anytime and anywhere as long as they have an internet connection. This is especially beneficial for working adults who may not have the time to attend traditional classes. Moreover, online learning allows students to review the materials repeatedly until they fully understand the concepts.Another advantage is the cost-saving aspect. Online courses are often more affordable than traditional classroom-based courses. Students can save money on commuting, housing, and textbooks. Additionally, online learning opens up opportunities for students who do not have access to certain courses or universities in their local area.Despite its advantages, online learning also has some disadvantages. The lack of face-to-face interaction with instructors and peers can be a drawback for some students. Students may feel isolated and miss out on social interactions that are often experienced in a traditional classroom setting. Moreover, self-discipline and time management skills are crucial for successful online learning, and not all students possess these qualities.In conclusion, online learning has both advantages and disadvantages. It provides flexibility and cost-saving benefits, but it may also result in a lack of social interaction and require strong self-discipline from students. As technology continues to advance, it is important to find a balance between online and traditional learning methods for optimal educational experiences.答案及解析听力：1-3 主旨题。

大学英语四级考试模拟试卷Part ⅠWritingDirections:For this part, you are allowed 30 minutes to write a letter of advice to your cousin about how to spend the first winter holiday in college. You should write at least 120 words following the outline given below.1、现在网上购物已成为一种时尚2．网上购物有很多好处，但也有不少问题3．我的建议Part ⅡReading Comprehension (Skimming and Scanning)Exchange Rates：A Brief History of Exchange RatesFor centuries，the currencies of the world were backed by gold．That is，a piece of paper currency issued by any world government represented a real amount of gold held in a vault by that government．In the 1930s，the U.S.set the value of the dollar at 8 single，unchanging level：l ounce of gold was worth $35．After World War II，other countries based the value of their currencies on the U.S.dollar．Since everyone knew how much gold a U.S.dollar was worth，then the value of any other currency against the dollar could be based on its value in gold．A currency worth twice as much gold as a U.S.dollar was，therefore，also worth two U.S.dollars．Unfortunately，the real world of economics outpaced this system．The U.S.dollar suffered from inflation(its value relative to the goods it could purchase decreased)，while other currencies became more valuable and more stable．Finally，in 1971，the U.S.took away the gold standard altogether．This meant that the dollar no longer represented an actual amount of a precious substance-market forces alone determined its value．Today，the U.S.dollar still dominates many financial markets．In fact，exchange rates are often expressed in terms of U.S.dollars．Currently，the U.S.dollar and the euro account for approximately 50 percent of all currency exchange transactions in the world．Adding British pounds，Canadian dollars，Australian dollars，and Japanese yen to the list accounts for over 80 percent of currency exchanges altogether．Methods of Exchange：the Floating Exchange RateThere are two main systems used to determine a currency's exchange rate：floating currency and pegged currency．The market determines a floating exchange rate．In other words，a currency is worth whatever buyers are willing to pay for it．This is determined by supply and demand，which is in turn driven by foreign investment，import/export ratios，inflation，and a host of other economic factors．Generally，countries with mature，stable economic markets will use a floating system．Virtually every major nation uses this system，including the U.S.，Canada and Great Britain．Floating exchange rates are considered more efficient，because the market will automatically correct the rate to reflect inflation and other economic forces．The floating system isn't perfect，though．If a country's economy suffers from instability，a floating system will discourage investment．Investors could fall victim to wild swings in the exchange rates，as well as disastrous inflation．Methods of Exchange：the Pegged Exchange RateA pegged，or fixed system，is one in which the exchange rate is set and artificially maintained by the government．The rate will be pegged to some other country's dollar，usually the U.S.dollar．The rate will not fluctuate from day to day．A government has to work to keep their pegged rate stable．Their national bank must hold large reserves of foreign currency to mitigate changes in supply and demand．If a sudden demand for a currency was to drive up the exchange rate，the national bank would have to release enough of that currency into the market to meet the demand．They can also buy up currency if low demand is lowering exchange rates．Countries that have immature，potentially unstable economies usually use a pegged system．Developing nations can use this system to prevent out-of-control inflation．The system can backfire，however，if the real world market value of the currency is not reflected by the pegged rate．In that case，a black market may spring up，where the currency will be traded at its market value，disregarding the government's peg．When people realize that their currency isn’t worth as much as the pegged rate indicates，they may rush to exchange their money for other，more stable currencies．This can lead to economic disaster，since the sudden flood of currency in world markets drives the exchange rate very low．So if a country doesn't take good care of their pegged rate，they may find themselves with worthless currency．Methods of Exchange：HybridsIn reality，few exchange rate systems are 100 percent floating，or 100 percent pegged.Countries using a pegged rate can avoid market panics and inflationary disasters by using a floating peg．They peg their rate to the U.S.dollar，and that rate doesn't fluctuate from day to day．However，the government periodically reviews their peg，and makes minor adjustments to keep it in line with the true market value。

大学英语四级模拟试题及答案篇1Part Ⅱ Reading Comprehension (35 minutes)Directions: There are 4 passages in this part.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the correspondingletter on the Answer Sheet with a single line through the center.Questions 21 to 25 are based on the following passage:Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a second,if they were controlled by clock.?The scientists who heard the signals did not tell anybody else.They were rather afraid to tell in case they frightened people.The signals were coming from a very small body—no bigger,perhaps than the earth.Was that why no light could be seen from it?Or were the signals coming from a planet that belonged to some other star??There was no end to the questions,but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets,or to us?So the news was notgiven to the newspaper.Instead,the scientists studied the signals and searched for others like them...Well,all that happened in 1967 and 1968.Since then scientists have learnt more about those strange,regular,radio signals.And they have told the story,of course.The signals do not come from a planet;they come from a new kind of star called a “pulsar””.About a hundred other pulsars have now been found,and most of themare very like the first one.?Pulsars are strong radio stars.They are the smallest but the heaviest stars we know at present.A handful of pulsar would weigh a few thousand tons.Their light—if they give much light—is too small for us to see.But we can be sure of this,no intelligent beings are living on them.21. The radio signals discussed in this passage____.A.were regularB.were controlled by a clockC.were heard in 1967 onlyD.were secret messages22. The radio singals were sent by____.A.a satelliteB.a planetC.a sky body which was unknown at that timeD.intelligent beings who were unknown at that time23. The scientists did not tell people about the signals because____.A.the singals stood for secret messagesB.people would ask them too many questionsC.they did not want to frighten peopleD.they stood for unimportant messages24. A pulsar is____.A. a small heavy star which sends out strong radio signals and cannot be seenB. a small heavy planet which sends out strong radio signals and cannot be seenC. a small heavy satellite which sends out strong radio signals and cannot be seenD. a small intelligent being who sends out strong radio signals and cannot be seen 25. Which of the following is true?A.One of the pulsars found by scientists sends radio signals.B.Pulsar began to send radio singals in 1967.C.Scientists have searched for pulsars for many years but found none.D.Scientists have found many pulsars since 1967.Questions 26 to 30 are based on the following passage:Over vast areas of every continent,the rainfall and vegetation necessary for life are disappearing.Already more than 40 percent of the earth's land is desert ordesert?like.About 628 million people—one out of seven—live in these dry regions.In the past,they have managed to survive,but with difficulty.[ZZ(Z]Now largely through problems caused by modern life,their existence is threatened by the slow,steady spread of the earth's deserts.Scientists still do not understand all the complex problems of the desert,but there have been many ideas for saving the land.Sandi Arabia has planted 10 milliontrees to help keep the sand from taking over fertile areas.The Israelis are again using some of the water collection systems left by the ancient people in theNegev desert.They plan to water their orchards with the extra water.Some Sahel farmers still raise cattle on their poor farm land,but before the cattle are sold,they are taken to greener lands in the south to get fat.26. What is the article mainly concerned?A.The problem of spreading desert.B.The rainfall and vegetation in desert areas.C.The water collection systems.D.The difference between modern life and ancient life.27. “one out of seven” refers to____.A.more than a third of the lands' earthB.the percentage of the earth's land that is desert-likeC.the number of people who live in dry regionsD.a day of a week28. In paragraph 2,“they are taken to the greener lands in the south.”Theyrefers to____.A.the Sahel farm landB.the farmersC.the cattlesD.the trees29. How many ideas for saving the land are described?A.Five.B.Two.C.Four.D.Three.30. Which of the following statements is true, according to the passage?A.The earth's desert are slowly spreading.B.One out of 10 people lives in dry regions.C.Their life in the desert is threatened now by traditional problems.D.New water wells can solve the problem in Africa's desert.Questions 31 to 35 are based on the following passage:Telephone, television, radio, and telegraph all help people communicate witheach other. Because of these devices, ideas and news ofevents spread quickly allover the world. For example, within seconds, people can know the results of anelection in another country. An international football match comes into the homesof everyone with a television set.News of a disaster such as an earthquake or aflood can bring help from distant countries within hours, help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast.How has this speed of communication changed the world? To many people,the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago,communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries,it took six weeks for news from Europe to reach America.This time difference influenced people's actions. For example, one battle, or fight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed.They would not have died if news had come in time.In the past,communication took much time than it does now.?There was a good reason why the world seemed so much larger than it does today.31. News spreads fast because of____.A.modern transportationB.new technologyC.the change of the worldD.a peace agreement32. According to this passage,____is very important to people in a disaster area.A.fast communicationB.modern technologytest newsD.new ideas33. Which of the following statements is true?A.The world now seems smaller because of faster communication.B.The world is actually smaller today.C.The world is changing its size.D. The distance between England and America has changed since the War of 181234. Two hundred years ago,news between the continents was carried____.A.by telephone and telegraphB.by landC.by airD.by sea35. The New Orleans Battle could have been avoided if the peace agreement had been signed____.A.by both sidesB.in timeC.in AmericaD.in EnglandQuestions 36 to 40 are based on the following passage:The concept of personal choice in relation to health behaviors is an important one.An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge.We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society.[ZZ)]The structure of American society allows us to make almost all our own personal decisions that may concern ourhealth.If we so desire,we can smoke,drink excessively, refuse to wear seatbelts,eat whatever foods we want,and live a completely sedentary life-style without any excuse.The freedom to make such personal decisions is a fundamental aspect of our society,although the wisdom of these decisions can be questioned.Personal choices relative to health often cause a difficulty.As one example,a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.?A multitude of factors,both inherited and environmental,influence the development of health?related behaviors,and it is beyond the scope of this text to discuss all these factors as they may affect any given individual.However,the decision to adopt a particular health-related behavior is usually one of personal choices.There are healthy choices and there are unhealthy choices.In discussing the moral of personal choice,Fries and Crapo drew a comparison.They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide.[ZZ)]Thus,for those individuals who are interested in preserving both the quality and quantity of life,personal health choices should reflect those behaviors that are associated with statistical probability of increased vitality and longevity.36. The concept of personal choice concerning health is important because____.A.personal health choices help cure most illnessesB.it helps raise the level of our medical knowledgeC.it is essential to personal freedom in American societyD.wrong decisions could head to poor health37. To “live a completely sedentary life?style”(Para. 1) in the passage means____.”A.to live an inactive lifeB.to live a decent lifeC.to live a life with complete freedomD.to live a life of vice38. Sound personal health choice is often difficult to make because____.A.current medical knowledge is still insufficientB.there are many factors influencing our decisionsC.few people are willing to trade the quality of life for longevityD.people are usually influenced by the behavior of their friends39. To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to____.A.improving the quality of one's lifeB.limiting one's personal health choiceC.deliberately ending one's lifeD.breaking the rules of social behavior40. According to Fries and Crapo sound health choices should be based on____.A.personal decisionsws of societyC.statistical evidenceD.opinions of friendsPart Ⅲ Vocabulary and Structure (20 minutes)Directions:There are 30 incomplete sentences in this part.For each sentence there are four choices marked A),B),C) and D).Choose the ONE answer that best completes the sentence.Then mark the corresponding letter on the Answer Sheet with a single line through the center.41. ____he thought of it,the stars seemed always large andclear before the dawn of Christmas Day.A.As forB.Now thatC.BecauseD.As soon as42.
