How would I, unable to speak the language, __3__ unfamiliar with local geography or transportation systems, set up __4__ and do research? It seemed impossible, and with considerable __5__ I sat down to write a letter begging off. Halfway through, a thought ran through my mind: you can't learn if you don't try. So I accepted the assignment.There were some bad __6__. But by the time I had finished the trip I was an experienced traveler. And ever since, I have never hesitated to head for even the most remote of places, without guides or even __7__ bookings, confident that somehow I will manage.The point is that the new, the different, is almost by definition __8__. But each time you try something, you learn, and as the learning piles up, the world opens to you.I've learned to ski at 40, and flown up the Rhine River in a __9__. And I know I'll go on doing such things. It's not because I'm braver or more daring than others. I'm not.

The hollowed-out A300 was __27__ of everything potentially harmful to the environment and sunk off the Aegean coast today. Not only will the sunken plane __28__ the perfect skeleton for artificial reef growth, but authorities hope this new underwater attraction will bring tourists to the area.The plane __29__ a total length of 54 meters, where experienced scuba divers will __30__ be able to venture through the cabin and around the plane's __31__ Aydin Municipality bought the plane from a private company for just under US $ 100, 000, but they hope to see a return on that __32__ through the tourism industry. Tourism throughout Turkey is expected to fall this year as the country has been the __33__ of several deadly terrorist attacks. As far as sunken planes go, this Airbus A300 is the largest __34__ sunk aircraft ever.Taking a trip underwater and __35__ the inside of a sunken A300 would be quite an adventure, and that is exactly what Turkish authorities are hoping this attraction will make people think.

However, these beasts of the sea do display a vast range of highly __28__ behaviors that appear to be driving their genetic development.The word "culture" comes from the Latin "colere," which __29__ means "to cultivate." In other words, it refers to anything that is __30__ or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are. For instance, having spent many generations hunting the fat marine mammals of the Arctic, the Eskimos of Greenland have developed certain genetic __31__ that help them digest and utilize this fat- rich diet, thereby allowing them to __32__ in their cold climate.Like humans, killer whales have colonized a range of different __33__ across the globe, occupying every ocean basin on the planet with an empire that __34__ from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey （猎物）.

Manufacturers would have nearly total freedom to test their self-driving technology on public roads. They would be allowed to send groups of self- driving cars on cross-state road trips, and even set up on-demand __33__ of self-driving cars, like the one General Motors and Lyft are building.Lawmakers in Michigan clearly want to make the state ready for the commercial application of self-driving technology.

Americans view five hours of TV each day, and while we know that spending so much time sitting 36 can lead to obesity (肥胖症) and other diseases, researchers have now quantified just how 37 being a couch potato can be.In an analysis of data from eight large 38 published studies, a Harvard-led group reported in the Journal of the American Medical Association that for every two hours per day spent channel 39 , the risk of developing Type 2 diabetes(糖尿病) rose 20% over 8.5 years, the risk of heart disease increased 15% over a 40 , and the odds of dying prematurely 41 13% during a seven-year follow-up. All of these 42 are linked to a lack of physical exercise. But compared with other sedentary(久坐的) activities, like knitting, viewing TV may be especially 43 at promoting unhealthy habits. For one, the sheer number of hours we pass watching TV dwarfs the time we spend on anything else. And other studies have found that watching ads for beer and popcorn may make you more likely to 44 them.Even so, the authors admit that they didn’t compare different sedentary activities to 45 whether TV watching was linked to a greater risk of diabetes, heart disease or early death compared with, say, reading.（五）A.announcingB.beneficialC.challengesmitmentponentF.contestsG.critically H.develop I.distributingJ.enhance K.entitled L.potentialM.properly N.qualified O.retainThe U.S. Department of Education is making efforts to ensure that all students have equal access to a quality education.

The initiative will help states and school districts support great educators for the students who need them most.“All children are 37 to a high-quality education regardless of their race, zip code or family income. It is 38 important that we provide teachers and principals the support they need to help students reach their full 39 ,” U.S. Secretary of Education Arne Duncan said. “Despite the excellent work and deep 40 of our nation's teachers and principals, students in high-poverty, high-minority schools are unfairly treated across our country. We have to do better. Local leaders and educators will 41 their own creative solutions, but we must work together to 42 our focus on how to better recruit, support and 43 effective teachers and principals for all students, especially the kids who need them most.”Today’s announcement is another important step forward in improving access to quality education, a 44 of President Obama’s year of action. Later today, Secretary Duncan will lead a roundtable discussion with principals and school teachers from across the country about the 45 of working in high-need schools and how to adapt promising practices for supporting great educators in these schools.（一）26-35：GMALC FJOIE （二）26-35：CIKJA BOGFM （三）26-35：HAGDI NJEBK （四）36-45：HFILC AGEBD （五）36-45：AKGLD HJOCE。

• 较难的一个例子：Husbands and children now do some of these jobs, a ____ that has changed the target market for many products. (06-12) 这里可以用两种判断方法 来判断横线处所填词的词性。第一种方法，用句子结构来判断，前面一句话，Husbands and children now do some of these jobs，这是一个完整的句子，主语husbands and children，谓语动词DO，宾语Some of these jobs；后面的that引导的是一个同位语从 句，它所修饰的中心词就是a后面需要填的词，而定语从句的中心词是名词，所以横线处 应填一个名词。第二种方 法，根据刚才所说的“a + 名词”的语法规则来判断，横线处应 该填一个名词，而且是一个可数名词的单数形式。正确答案是situation。这句话的意思是 “丈夫和孩子现在也做一些 这样的工作了，这种情况就改变了许多产品的目标市场。”
• 2. 当出现“一个完整的句子 + ，____ + 名词/介词”的结构时，逗号后 边的部分是伴随状语，表示伴随状态或者表示原因，应当填动词加ING形 式或动词加ED形式。当这个动词与句子主语是主动关 系，填动词加ING形 式，当两者是被动关系，填动词加ED形式。
• 举例说明：
• The rainfall is increased across south america, ___ floods to peru. (06-6) 根据独立主格结构原则，应该填动词ing或动词ed，选项中只有 bringing符合要求。从意思来看，bring“带来”与rainfall“降雨”之 间 是主动关系，即“the rainfall brings floods”，所以用bringing无论从 意思上还是结构上都符合要求。

英语四级选词填空练习题及答案英语四级选词填空练习题及答案：There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.1.The study of the effects of salt on high blood pressure was carried out ______.a.as members of the same family tend to use similar amounts of saltb.to explore the long-term use of a sodium based substancec.because it was proven that salt caused high blood pressured.because of the availability of chemically pure salt and its derivatives2.The main difference between "S" and "R" rats is their ______.a.need for sodium 22b.rate of matingc.reaction to saltd.type of blood3.We can infer from the article that sodium 22 can de used to ______.a.control high blood pressureb.cure high blood pressure caused by saltc.tell the "S" rats from the "R" ratsd.determine what a sodium chloride metabolism is like4.The most beneficial results of the research might be ______.a.development of diets free of saltb.an early cure for high blood pressurec.control of genetic agents that cause high blood pressured.the early identification of potential high blood pressure victims5.Which of the statements best relates the main idea of this article?a.When salt is added rats and human beings react similarly.b.The near future will see a cure for high blood pressure.c.The medical field is desperately in need of research.d.A tendency toward high blood pressure may be a hereditary factor.答案：acddd英语四级选词填空练习题及答案：Directions: In this section, there is apassage with ten blanks.

You may not use any of the words in the bank more than once.Questions 47 to 56 are based on the following passage.（1）Once the world embraced the automobile, the days of depending on horses, bicycles, ferries, and trains quickly slipped into the past. People were __47__ with the speed of the automobile but they were also enjoying the personal freedom that the automobile gave them. Owning a car gave people the freedom to go anyplace a road __48__. This allowed people to and at their own __49__. This independence gave the car a popular edge over buses and trains. The popularity of the automobile made it the __50__ of the transportation system. The automobile changed our lives when it created a giant industry that offered more and more jobs. The automobile made it possible for people to live in areas __51__ from their work place. This caused cities to grow and made suburban living more convenient. Of course, with more places to go, more __52__ roads had to be built. The automobile caused a __53__ effect.

It will be interesting to see what the future holds for the automobile. We have already seen signs of the use of solar energy in this area. As long as man has a brain, the future of the automobile is __56__.（2）A college education is an investment in the future. But it can be a 47 one. The College Board 48 that the costs at a four-year public college in the United States increased 10% this past school year. That was less than the 13% increase the year before, but still much higher than the inflation 49 Public colleges and universities still cost a lot less than private ones.Financial aid often helps. But financial experts 50 parents to start college savings plans when their child is Still very young.All fifty states and the District of Columbia 51 what are called 5-29 plans. These plans are named after the part of the federal tax law that created them in 1996. States use private investment companies to operate the 52 of the programs.Every state has its own rules 53 5-29 plans. Some of the plans are 54 of state taxes. And all are not required to pay federal taxes. However, the government could start to tax withdrawals in 2011 if Congress does not change the law.5-29 plans include investment accounts that increase or decrease in value with the investments they contain. Families must decide how 55 they want to put money into stocks, or other investments.Another kind of 5-29 plan lets parents begin to pay for their child’s education in 56 and long before theirchild starts college. This kind of savings program is called a prepaid tuition plan. The money goes into an accountThere is progress toward a possible treatment for lung diseases such as SARS (severe acute respiratory syndrome). Researchers have learned more about how the SARS virus works: it 47 with a system in the body that uses enzymes (酶) to control blood pressure and fluid balance. Scientists say the virus 48 to an enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.A team from Europe and Asia reported the 49 in Nature Medicine. Doctor Josef Penninger of the Institute of Molecular Biotechnology in the Austrian Academy of Sciences was the 50 writer of the report. The discovery could lead to a new 51 of treating not just SARS but also other diseases that can cause lung failure. These include avian flu (禽流感) and influenza in humans.The first 52 of SARS were discovered in Guangdong province, in southern China, in November of 2002. SARS was not 53 as a worldwide threat until March of 2003. The disease spread to 26 countries, most of them in the Asia-Pacific area. An estimated 8, 000 people had SARS. More than 770 of them died, or about 10% , a 54 high rate.The World Health Organization warned people not to travel to 55 areas. The 56 hurt international travel and business. The WHO says the disease stopped spreading by July of 2003. As a result of SARS, the health agency got new powers to act before a government officially announces a crisis.（4）To call something “marginal” means it is not very good. Farmers have their own way to 47 marginal land: It is the last to be planted under good conditions, and has the 48 to be avoided under poor conditions. Low 49 soil is not the only reason land could be considered marginal. It might be in an area where rainfall is 50 or where a hillside might rise too steeply.There are uses for marginal land, however. Most often it is used as grassland. Grasses provide excellent51 for grazing (吃草) animals like cattle, sheep and goats. Grass seed can be bought from a foreign supplier or52 grasses can be used. However, using marginal land for grazing is not a simple issue. There is a 53 of overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the soil and can make it too hard for growing. A(n) 54 way to reduce the harm is to move animals from one field to another. This method is known as rotational grazing (循环放牧) which is extremely important for marginal land.Another use for marginal land is for tree crops. Studies have 55 that the white pine and loblolly pine (火炬松) are two kinds of trees that grow well on such land. They grow fast and provide good quality wood. Another tree is the poplar (白杨), found in many parts of the world.Failure to take the care needed to protect marginal lands can make a bad situation worse. But goodChina is casting such a huge shadow on the United States that many Americans are trying hard to learn the Chinese language with an effort to keep their competitive edge."Interest in learning Chinese among American youth and their parents has grown 47 in the past five years," said Vivien Stewart, vice president at the Asia Society, a US group trying to bridge the 48 between Americans and the peoples of Asia and the Pacific.China's rapid progress is driving the interest to 49 the language, experts say. "The Chinese rich cultural traditions and 50 economy mean that it is now essential for all of our students to be better prepared to engage them and seize opportunities together," said Michael Levine, Asia Society' s executive director of education.A 2004 College Board survey found that 2,400 high schools--an 51 number--would be interested in52 the Advanced Placement (AP) courses in Chinese language and culture when the courses become available in 2006.China, the world' s most populous ( 人口稠密的) nation, is 53 to the United States because it is a leading trader, consumer and investor. It has 54 the United States as the world's largest consumer and could become the second largest economy in the world, in the next two to three decades.Even though the US State Department has regarded the Chinese language extremely important to national prosperity , the" 55 conditions to support recruitment of students and teachers as well as the growth of high（6）Can money buy happiness? Yes, 47 the authors of a new study---but only to a point.Psychology has shown that richer people generally rank the overall quality of their lives more 48 than poorer people do. At the same time, their actual happiness seems to be 49 less by their ability to buy more than by being able to keep up with those with comparable resources in their own age group."Our findings point to the possibility that, rather than promoting overall happiness, continued income growth could 50 an ongoing consumption race where people have to consume more and more, just to maintain a 51 level of happiness," writes Glenn Firebaugh of Pennsylvania State University.The study was 52 at the American Sociological Association's 100th Annual Meeting. Whether the rich are happier as a whole than their less 53 fellows is becoming an increasingly hot topic for debate. Recent years have 54 many writings on the "science of happiness." Richer people are happier because money can help purchase goods and services and it is the 55 of these materials that increases one's enjoyment of life and one's sense of well-being. Firebaugh and his colleagues measured the age, total family income, and general happiness of 56 aged 20 to 64, generally considered the working lifespan (工作寿命) for most Americans.Regardless of such standards as physical health, education, and marital status (婚姻状况), people's happiness was affected by what others earned. The higher the income of others in one's age group, the lower one'sKitchen duties may have traditionally been viewed as women’s work, but not at the White House. Until now: Cristeta Comerford has been named executive chef (厨师) .After an_ 47 six-month search, first lady Laura Bush announced Sunday that Comerford was chosen from hundreds of 48 to head the executive kitchen. A naturalized U.S. citizen from the Philippines, she will be the first woman and first 49 to hold the post. The 42-year-old Comerford has been an assistant chef at the White House for 10 years. She worked under former executive chef Walter Scheib Ill, who 50 in February.Scheib said Sunday that Comerford was 51 the best assistant he had in his 30-year career and is a wonderful choice to take over.

For 50 , children who had televisions in their bedrooms--and 51 watched more TV--scored lower on standardized tests than those who did not have sets in their rooms. In contrast, the study found having a home computer with 52 to the Intemet resulted in comparatively higher test scores."Consistently, those with a bedroom television but no 53 home computer had, on average, the lowest scores and those with home computer but no bedroom television had the highest scores," wrote study author Dina Borzekowski of Johns Hopkins University. The American Academy of Pediatrics has 54 parents to limit children’s television viewing to no more than one to two hours per day--and to try to keep younger children away from TV altogether.In two other studies published in the same journal, children who 55 watched television before the ageof 3 ended up with lower test scores later on, and children and adolescents who watched more television were less选词填空答案(1) 47-56 N E O A M L J I G B （2）47-56 G B E I C L N K A M（3）47-56 M C J G A E L I O D （4）47-56 F B J E A K N D L H（5）47-56 C K G A I N D F M O （6）47-56 C N E H A J B K F M（7）47-56 D K B I F H L A O E （8）47-56 J G M K D E B I C F。
