【解析】
【详解】句意：——你表弟什么时候离开的他的家乡？——他离开了几乎3年了。根据leave离开，短暂性动词，不能和时间段连用，be away离开，是延续性动词，和时间段连用，根据for nearly three years是时间段，排除B/C；根据when什么时候离开的，第一句用一般过去时态；故选D

【详解】句意：——海伦，你认识那个穿丝绸衣服的女人吗? ——是的，很了解。上个月她嫁给了一个日本人。
考查固定搭配和时态。marry“嫁，娶”，动词；固定搭配marry sb意为“嫁给某人；与……结婚”；be / get married to sb.意为“与某人结婚”，marry一般不与介词with连用，所以选项A、C和D形式错误。根据last month，可知时态是一般过去时，所以用动词过去式。故选B。

By not doing anything you are worrying yourself.”“Okay,” she says. “I see what you mean.”When she calls, the vet quickly finds the problem. He tells her to bring the cat in. And if he is right about the cat, he cantreat(治愈) it right away.。

The old name for Green Island was Huoshandao, meaning―fire-burning island‖. The island got its name because people on the island used to set up fires at night to help people who went fishing home. Another story goes that in the Qing Dynasty there was a fire and most of the island’s trees and grass died. The coastline of the island is only 20 kilometers long, the tallest mountain is only 281 meters high and the island is only15 km2, but it is attracting (吸引) a growing number of tourists.Green Island has a lot of interesting that makes it a place where people like to go: seaside, a clear white beach, green grasslands, seawater, hot springs, beautiful undersea sights, and a great many plants and animals. Another thing of Green Island that people are interested in is its rocks in different shapes.―Sleeping Beauty‖ and―Pekinese Dog‖ are the two most strangely shaped ones. There are also other interests with one cannot miss. The green hills, blue sea, clear sky, and ocean gentle winds make a―must‖ for you.41. From the article we know Green Island is ________________.A. very largeB. 281 meters longC. in the Indian OceanD. 33 kilometers from Taitung42. According to the two stories, people on the Green Island used to_________________ .A. meet a lot of visitorsB. set fire to get warmC. make a living by fishingD. cut down too many trees and grass43.

Here are some tips for you to be happy.Make enough money to meet your basic needs: food, shelter, and clothing.In the US, that magic number is $40,000 ayear. Any money you make beyond（超过）that will not necessarily make you happier. Once you make enough money to support your basic needs, your happiness is not affected by how much money you make._______or move to where other members are - so you can see them more.Now, people follow jobs around the country and sometimes around the world. As a result, our relationships with our friends and family have a far greater effect on our happiness than our jobs do. So next time you think about moving, think of a place where most of your friends and families live.Find happiness in the job you have now.Many people hope the right job can change their level of happiness. But happiness research makes it clear that changing jobs can't bring you happiness. If you want, you will make the best of any job. If you have good relationships with people, you won't depend on (依赖) your job to give your life a greater sense of meaning. You will find it in your communication with the people you care about.If you are unhappy for a long time, you should ask an expert（专家）or a doctor for help. For more advice, click here. I hope you will be happy all the time.44. The writer wrote this passage mainly to_______.A. make friendsB. give advice on how to be happyC. put on an advertisementD. ask for help45. What is the topic sentence for the third paragraph?A. Ask family members for help.B. Borrow money from family members.C. How to make family members be happy.D. Stay close to friends and family.46. The passage is from_______.A. the InternetB. a magazineC. a newspaperD. a book reviewCWhen my family moved toAmerica 2010 from a small village inGuangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young people should always respect(尊敬) elders. Unluckily, this rule led to my very first embarrassment in the United States.I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long talk about how sensitive(敏感) Americans are and how they dislike the description ―old‖. I then walked back to the table and said sorry to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were no longer angry.In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience. Young people always respect older people because they know they can learn from their rich experience.However, in the Uni ted States, people think ―growing old‖ is a problem since ―old‖ shows that a person is going to retire or that the body is not working well. Here many people try to keep themselves away from growing old by doing exercises or jogging, and women put on makeup, hoping to look young. When I told the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had failed to stay young. I had told them something they didn’t want to hear.After that, I changed the way I had been with older people. It is not that I don’t respect them any more; I still respect them, but now I don’t show my feelings through words.47. Jack brought the couple their food very fast because _______.A. the manager asked him to do soB. he thought he should respect the elderlyC. the couple wanted him to do soD. he wanted more pay48. What does the underlined word ―embarrassment‖ mean in the first paragraph?A. 尴尬B. 拮据C. 潦倒D. 敬仰49. In the writer’s hometown, _______________________.A. people dislike being called ―old‖ because they can’t learn a lot from othersB. many people reach the age of seventy or eightyC. people are proud of being oldD. the elderly are the first to get food in restaurants50. Which of the following is TRUE?A. The more Jack explained, the angrier the couple got.B. Jack wanted to show his feelings through words after his experience.C. The manager went back to the table and apologized to the couple.D. From this experience, Jack learned more about American culture.五、任务型阅读（共5空，每空1分，满分5分）We need to be responsible for our environment. Being a frugal consumer (节俭的消费者) is one way to help. But, what exactly does that mean?Use It UpYou can use things up instead of wasting them. Squeeze that last bit of toothpaste(牙膏) out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.Wear It OutYou do not always need to have new things. If your sports trainers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.Make It DoWhen something you want is not on hand, look for something else that you already have to take its place.
