AI'm a strong believer that learning different languages makes you look quite good when you're in a foreign country and understand and speak the language. The list below is 4 apps (计算机应用程序) that will help you learn a foreign language! You can download (下载) them for free.Babbel-Learn LanguagesBabbel is an excellent language tool to help you progress step by step with learning a new language. It helps you learn grammar along the way as you work your way through the tasks and assignments (作业).

It's completely free too! It's well designed, looks great and will help you learn, remember and progress with just a little bit of time every day.Tandem：Language ExchangeRather than have you work through tasks and memorize different things, the app lets you match with people who share your interests but speak the language you want to learn. You can then have text, voice and video conversations with people who want to learn your native language, and in return you learn theirs, all by simply communicating with each other.

They are expensive.C. They are free to download.D. They contain many tests.BReading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing. com turns the page on the traditional idea of a book group.Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossers to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual (虚拟). The site now has more than one million members in more than one hundred thirty-five countries.4. Why does the author mention book groups in the first paragraph?A. To explain what they are.B. To introduce BookCrossing.C. To stress the importance of reading.D. To encourage readers to share their ideas.5. What does the underlined word “it” in Paragraph 2 refer to?A. An adventure.B.

Pass it on to another reader.D. Mail it back to its owner.7. What is the best title for the text?A. Online Reading：A Virtual TourB. Electronic Books：A New TrendC. A Book Group Brings Tradition BackD. A Website Links People through BooksCPeople enjoy talking about “firsts”. They like to remember their first love or their first car. But not all firsts are happy ones.One of history’s bad but important firsts was the first car accident. Cars were still young when it happened. The accident took place in New York City in May 1896. A man from Massachusetts was visiting the city in his new car. At that time, bicycle riders were still trying to get used to the new set of wheels on the road. No one was sure who was to blame for it. Anyway, the bike and the car hit each other hard. The man on the bike was injured. The driver of the car had to stay in jail and wait for the hospital report on the bicycle rider. Luckily the rider was not killed.Three years later, another car accident took place. It was again in New York City. A man named Henry Bliss stepped off a streetcar. He was hit by a passing car. Once again, no one was sure just how it happened or whose fault it was. The driver of the car was put in jail. Poor Mr. Bliss became the first person to die in a car accident.8. Which of the following is true?A. The first driver came from New York City.B. Both of the two car accidents killed a person.C. The second car accident didn’t happen in the same city as the first one.D. No one knew how the two accidents had happened.9.

The word “jail” in this passage means ________.A. police stationB. prisonC. schoolD. office11. The main idea of the passage is ________.A. not all firsts are happy onesB. two of the first car accidentsC. two unhappy “firsts”D. bicycle riders get used to carsDThe next time you make yourself a hot cup of tea or coffee, you might want to let it cool down a bit before drinking. Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer.In fact, the United Nations' cancer research agency decides to list hot drinks with lead, gasoline and exhaust fumes as “possibly carcinogenic (致癌的)”. In other wor ds, each one could cause cancer.Researchers at the International Agency for Research on Cancer found evidence that drinks at temperatures above 65 degrees Celsius, when swallowed, can cause cancer of the esophagus (食道)．The researchers examined findings from other studies where tea and coffee were often served at 70 degrees Celsius or above. Those studies were completed in China and South America. In developed countries, health experts have linked esophageal cancer to smoking and alcoholic drinks.However, this form of cancer is more common in areas where people have drinks at very high temperatures.In Europe and the United States, many people drink coffee and tea at temperatures around 60 degrees Celsius. And they often add milk which lowers the temperature considerably. However, tea-drinkers in South America often enjoy their beverages at closer to 70 degrees Celsius.In 1991, the World Health Organization listed coffee as “possibly carcinogenic”. WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink itself.Christopher Wild is the director of the IARC. He said that the results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.12. Who most probably suffers from cancer of the esophagus?A. A girl who likes cold milk.B. A man who drinks very hot tea.C. A woman who likes coffee.D. A man who works at IARC.13. Why did the WHO remove coffee from “possibly carcinogenic” list?A. Because people don't like coffee any longer.B. Because people drink coffee at 60 degrees Celsius.C. Because coffee has nothing to do with cancers.D. Because temperature is more dangerous than coffee itself.14. How does the author mainly support the theme of the text?A. By studying examples.B. By starting arguments.C. By providing research results.D. By showing backgrounds.15. What can be a suitable title for the text?A. Hot Drinks Linked to CancerB. Reduce Having Hot DrinksC. Danger of Drinking Hot DrinksD. Healthy Drinks第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

So while I was taking pictures, Maia, wanting to prove her 18 as anassistant, began interviewing a couple in the same ship. Unable to spell words, she 19 their answers in crayon. Then when we sat together at lunch, my daughter 20 the kids’ meal and requested the salmon (三文鱼).

I was impressed by how 24 fearless she was when we dived along a reef(礁石). And I was 25 by how she cleverly worked out that she could order chocolate cake from room 26 alone. But it was on the 27 home, when my glued-to-my-arm kid said it was okay that the airline didn’t 28 us together, that I realized how much travel was 29 her.

And we 34 at an orphanage (孤儿院) in Africa, where she learned the meaning of love and care.Travel has also helped Maia develop important life 35 such as independence, problem-solving, and communication.

Here are some steps to follow when preparing for the perfect video interview.Step 1: Start with the basicsBefore your interview, find out what platform or application the school uses for video interviews, and make sure that you know how to operate it.You need to set up a clear and focused interview environment. You also need a strong internet connection.Step 2: Get prepped (做好准备)Once the interview begins, resist the urge to watch yourself, and make sure you are looking at the camera as much as possible. Try to anticipate the questions that they will ask you. Interview questions all boil down to three basic categories:Tell us about yourself.What do you bring to our program/why should we admit you?Do you have any questions about the school?Before the interview, prepare at least two to three minutes on each of these topics.Step 3: PracticePractice your answers with a friend or mentor. Get them to ask you questions and answerthem over video. If possible, work with a person who is fluent in the language of your interviewers, and get them to give you notes and comments about pronunciation or presentation.Step 4: Don’t just interview... converseInterviews are about getting to know you as a person and how well you can interact with others. Though you may have extensive notes, try to act natural - do not read directly from any prepared statements, and don’t memorize answers to repeat. Listening is just as critical as speaking in this situation, too. Make sure you understand the question that is posed to you and ask an interviewer to repeat it or expand upon it if you feel you are confused.36．In preparing for the perfect video interview, you need to ________.A．have quick access to the Internet B．know how to operate the interviewC．fill out an application on the platform D．find a suitable environment for the interview 37．Once the interview begins, what should you keep in mind?A．Keeping quiet unless asked to talk.B．Making eye contact as much as possible.C．Expecting the questions that are often asked.D．Preparing answers on some of thequestions.38．Which of the following is TRUE about Step 3?A．You should be fluent in the language of your interviewers.B．Practicing with your friend over the phone may be helpful.C．Practicing in advance may help improve your performance.D．Notes and comments from the interviewers are practical.39．When doing an interview, you ________.A．are supposed to memorize answers to repeat B．must ask the interviewers to explain the questionsC．can read prepared statements as naturally as you can D．should attach equalimportance to listening as speaking40．Who is probably the author of the passage?A．An expert in university admissions.B．A visitor to different universities abroad.C．An editor in charge of a travel magazine.D．A student applying for universities overseas.When Milla Bizzot to finished her first 24-hour obstacle race, she went shoulder to shoulderwith experienced competitors, ran 36 miles and completed hundreds of obstacles, all at the age of 9.“There are some double takes on the course, but she has been an inspiration to people who see her out there competing like that,” said Christian Bizzotto, Milla’s father and coach, who was proud of her. Milla is very fit for her age, and she proved it in completing the BattleFrog Xtreme 24-hour race in Miami.Milla also used the event to inspire other kids to be active, and show how competing in obstacle racing has helped her deal with being bullied at school. “We wanted to make her feel more empowered and make her feel that she wasn’t weak, and that changed her whole mindset,” her father said.In preparing for the 24-hour race, Milla trained 20 hours a week for 90 days, doing exercise in the gym for 4 hours every day after school.“The reactions are 90 percent good, but some are totally negative,” Christian said. “I’ve had people message me on Facebook saying I’m a child abuser, and that no 9-year-old should be doing a 24-hour race. But her own doctors were there supporting her and cheering her on. I want her to be a kid, and this is just something she really wants to do.”CrossFit and obstacle course racing have also helped Christian turn around his life. He got injured in a motorcycle accident. After he was finally able to get around without using a walker, he began his recovery by going for walks on the beach with Milla, and then began running every day.Next, he joined a CrossFit gym and enjoyed it so much that he opened his own gym to train others for events like CrossFit, BattleFrog and Spartan races. “I just wanted to create a hero that Milla could look up to,” he said.Next up for Milla is an invitation-only “Athletes Race”. Competitors also have to raise $5,000 for charity.41．Christian Bizzotto, Milla’s father and coach, ______.A．was very strict with MillaB．was satisfied with what Milla didC．lost his legs in a motorcycle accidentD．threw his walker with the help of CrossFit42．What can we learn about Milla?A．She was always bullied by her schoolmates.B．She began to run because she was physically weak.C．Her father wanted her to get benefit from the obstacle race.D．She became more confident after the 24-hour obstacle race.43．During her training for the 24-hour obstacle race, Milla most probably _________.A．had two days’ rest every weekB．was always running with her fatherC．spent over 4 hours every day of a weekD．took a hit because her father was injured44．The reactions Christian got on the Internet ______.A．told us that Milla had a hard childhoodB．showed that he was a real abuserC．encouraged Milla to challenge more difficult runsD．were mixed but what Milla did was supported by her doctors45．What Christian did after his injury was mainly to ______.A．make money to open a gymB．set a good example to MillaC．make money to raise his familyD．get recovered as soon as possibleSeveral new species of tropical birds have been found on remote islands in Indonesia. Researchers have discerned the Wakatobi sunbird, a new species that lives on the small Wakatobi Islands, located in central Indonesia. They also studied olive-backed (橄榄背的) sunbirds and black sunbirds and found that some of the birds they examined actually belonged to some previously unrecognized species.The new Wakatobi sunbird looks similar to the olive-backed sunbird, but has darker feathers, shorter wings, and a higher-toned song. Zoologists believe that because it has such short wings, it never spread beyond the tiny islands. The olive-backed sunbird, however, can fly long distances, so it was able to inhabit other locations.These discoveries were part of a long-time cooperation between scientists at Trinity College Dublin and Universitas Halu Oleo in Sulawesi, Indonesia.“Specifically, we became interested in the Wakatobi sunbird because of the work of Ernst Hartert, a German bird expert active at the beginning of the 20th century,” Fionn O Marcaigh, first author on the paper, says. “He described the Wakatobi sunbird as a population with distinctive dark feathers, but he and the rest of the scientific community eventually decided that it was only a subspecies of the widespread olive-backed sunbird. We were eager to use modern methods to put this to the test.”For their research, scientists used DNA, recordings of songs and body measurement analysis to compare the sunbirds they studied, “We used a system called integrative taxonomy, which combines data on a number of aspects of the birds, including their songs, feathers, and body structures,” O Marcaigh says. “We recorded their songs using digital recorders, measured live birds caught and released by licensed netters, and used computational statistics to analyze the differences.” The scientists also obtained genetic samples which they analyzed in the lab and they found that the patterns they found were also reflected in the birds’ DNA．“I’m excited that we’ve added to the list of known species from this wonderful part of the world,” O Marcaigh says.46．What does the underlined word “discerned” in paragraph 1 probably mean?A．Overestimated.B．Imagined.C．Overlooked.D．Identified. 47．How does the Wakatobi sunbird differ from the olive-backed sunbird?A．It has colorful wings.B．It flies shorter distances.C．It lives throughout Indonesia.D．It sings more beautiful songs.48．What can we know about Ernst Hartert?A．He is a scientist from Universitas Halu Oleo.B．He still takes an active part in bird research.C．He is the first scientist to use DNA to study birds.D．He inspired the researchers’ interest in the Wakatobi sunbird.49．Why did O Marcaigh study the Wakatobi sunbird?A．To determine its category.B．To investigate its habitat and behavior.C．To analyze its genetic makeup.D．To continue the study of Ernst Hartert. 50．Which aspect of the research does paragraph 5 mainly talk about?A．Its methods.B．Its theories.C．Its impact.D．Its background.To put it simply, stress can be the father of growth, while a crisis can be the mother of innovation. The notion that great good can emerge from great adversity (逆境) is as old as the legend of the great phoenix (凤凰), who not only arises but soars to new heights from its own ashes.In 1598, William Shakespeare penned the play As You Like It. One of the most famous lines from that play is spoken in Act 2 Scene 1 by Duke Senior, “Sweet are the uses of adversity which, like the toad (癞蛤蟆), ugly and venomous, wears yet a precious jewel in his head.” Even 500 years ago, the potential value of adversity was recognized, not by a great healer, but by a great playwright. Can this really be the case?Fast-forward to the great silent film star Mary Pickford. She was called the most popular actress in the world in the 1910s and 1920s. Failing to continue acting with the advent of the “talkies”(movies with recorded sound), she co-founded the film company United Artists. Shifting her talents to producing and directing, she became the most powerful woman in the entertainment industry. She once noted, “You may have a fresh start any moment you choose, for this thing that we call ‘failure’ is not the falling down, but the staying down.”Rather than fear and try to avoid adversity, perhaps we should accept the inevitability (必然) of adversity and prepare for it. Indeed, positive things can emerge from adversity.Adversity reveals true opportunities for those preparing to take advantage. Dr. John Krumboltz’s happenstance theory states that career and life development is best fostered by preparing for opportunities that you may not know even exist in the current moment. Numerous unpredictable factors are potentially shaping the future. These include the crises adversity brings.In Friedrich Nietzsche’s book, Behold the Man, the German philosopher writes that a person who has “turned out well” could be recognized by the ability to take advantage of and prosper from adversity, just as he wrote before, “What does not kill him makes him stronger.”So, the next time adversity enters your life, will you run from it, or will you embrace it and use it as a step ping stone to greater happiness and success?51．Why does the author quote the line from Shakespeare’s play?A．To emphasize the great wisdom of Shakespeare.B．To highlight the beauty of Shakespeare’s language.C．To challenge the conventional belief regarding adversity.D．To show the long-standing recognition of adversity’s value.52．What is conveyed through Mary Pickford’s story?A．Fame can block one’s achievements.B．Strong determination overcomes adversity.C．Accepting adversity results in positive outcomes.D．Courage in the face of challenges leads to success.53．What is the idea behind Krumboltz’s happenstance theory?A．Embracing uncertainty.B．Managing life’s challenges.C．Seizing hidden opportunities.D．Focusing on personal growth.54．What is the author’s attitude towards adversity?A．Cautious.B．Favorable.C．Neutral.D．Doubtful. 55．What does the passage mainly talk about?A．Finding value and opportunity in facing adversity.B．Stress as the primary cause of growth and innovation.C．How to avoid adversity and negative experiences in life.D．Historical figures who failed to overcome adversity effectively.阅读下面短文，并根据题目要求用英语回答问题(请注意问题后的字数要求)。

The man decided to ride on a plane and fly all the way from Los Angeles to see his old friend. After finally seeing the cat,Robert immediately recognized his cat and burst into tears.

People have become more health conscious and try to take better care of their bodies by eating more healthily and exercising more regularly to lose any unnecessary fat that they may have.Not only are people being more careful about what they eat, they are also concerned(关心) with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so-called "plastic" fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients in a quiet restaurant with a more comfortable atmosphere. At home, they also try to take enough time to eat a relaxed dinner without phone or TV interruptions.While dieting may be viewed as beneficial, it has also become a serious problem for Americans, particularly for young women. Dieting for them has actually become a psychological(心理的) addiction. They eat so little that they can lose as much as fifty percent of their total body weight, and although they look like skeletons, they still insist that they are fat.The current wave of exercising, dieting and the problems produced have caused many organizations to begin educating the public. Many schools, hospitals, health organizations, newspapers and magazines, for example, are offering classes, printing articles and so on to inform the public of the way to exercise and diet of the dangers of dieting too rapidly, and of the places people can go for medical help if they find themselves on the road to "diet addiction".8. These days people are dieting more because ______.A. they are getting fatter and fatterB. they realize the danger of junk foodC. they grow aware of healthD. they eat more healthily9. Which way of eating is strongly advised in the passage?A. Enjoying food with phones on.B. Finishing dinner in a short time.C. Avoiding a salad or a sandwich.D. Eating in a relaxed atmosphere.10. If you are getting into "diet addiction", what should you do?A. See a doctor.B. Keep dieting.C. Take exercise.D. Attend classes.11. What is the last paragraph mainly about?A. What organizations are offering medical service.B. Where people with dieting addiction can go for help.C. How people are helped to solve dieting problems.D. What causes the organizations to educate the publicDThere is always something that happens in the world that everyone fears will happen to their town，city or country：natural disasters．The scariest part of it is that no one will ever see it coming．Though technology helps us prepare，but it never actually tells the people when it's going to hit．It is always estimated but the result is never 100% accurate．However，that is not the point of this article．Two different natural disasters in two different parts of the world have happened in the past few weeks．One was a major flood that has hit Louisiana in the United States．The other was an earthquake that hit Amatrice，Italy．However，there is a major difference in the news coverage of the two tragedies．As for the flooding in Louisiana，it is reported that this disaster is the worst to hit the United States since Super-storm Sandy and it'll cost at least ＄30 million．In only the first couple of weeks，13 people had died．However，like me，many people did not hear about this tragic event．I did not learn about it until about three weeks after it happened．In Italy，however，it covered all media instantly．The earthquake in Italy happened on Tuesday morning．That same day，I was on Twitter and that was all that was over the news feed．Every other post was about the earthquake．Some would have the opinion that Amatrice，Italy was one of the most beautiful towns in that country．I got in deep sorrow because there were more people killed in this quake than the flooding．So far，they have a total of 73 dead and over one hundred missing．I understand that technically the earthquake in Italy was worse than the floods in Louisiana．However，I believe that if a natural disaster happens，they all should beequally covered and taken equally seriously．We are one world united and should be there for all of the people who are in need of help．We may not be able to accurately predict disasters but，we can surely lend a hand out for the needy．12. What really concerns the author about the two natural disasters？______A. The death and the injured.B. The media report.C. The government's responsibility.D. Their economic loss.13. Why did the author learn about the flood so late______A. He didn't care about the flood.B. He felt nervous about the news.C. The media didn't cover it in time.D. The flood frightened the author a lot.14. What can be inferred from the passage______A. Italy isn't good at predicting the natural disasters.B. All natural disasters should be covered equally.C. The world should be united into one instantly.D. America should help Italy predict natural disasters.15. How is the text mainly developed？______A. By making a comparison.B. By following the time order.C. By listing some examples.D. By analyzing the causes.Reasons to Consider Learning a Second LanguageIn our current society，having the ability to understand a second language is becoming increasingly valuable．(1) ．So take a look at why this is such a valuableskill to have．You will be more competitive in the job market．Businesses are always looking for people who are bilingual to be translators and to communicate with non-English speaker．Bilingual employees get paid 5%-20% more than people who only speak one language．(2)You can get credit for it during college．If you study another language at a university，you will get credit （学分）toward graduating．You can start from the very beginning and learn a brand-new language or continue on from what you were studying in high school．Be aware，however，thatcollege classes can move quickly and are considered to be difficult at times．(3) You can study abroad in a wider range of countries．Studying abroad is an amazing experience that everyone should take advantage of．About 79% of Americans believe that students should seize the opportunity to spend a semester in another country．(4) Learning another language can help expand the number of countries you can choose from．Learning a language is a big commitment and is not easy by any means．If you don't have the time to learn a language in school，there are still many，way to become proficient in another language．One program to look into is Livemocha which is a free online program where you can learn a foreign language．(5) There are many other countries and written resources to consider as well．A．This is only one suggestion．B．So only take what you can handle．C．Many people learn a language in order to get high marks．D．There are a wide range of countries that you can choose from．E．You can even go for a major in a language if you get far enough along．F．Being able to communicate in more than one language can open countless doors．G．Having knowledge of a second language can make you stand out in the jobmarket．16.
