能力提升Ⅰ.阅读理解My decision to travel around China lay merely with my curiosity about the place. Before coming here, China seemed alien to me—a place that I expected to be hugely dissimilar from my own British culture.After travelling from Beijing up to Xi'an, I wanted to challenge myself by choosing a smaller town—Xiahe, in Gansu Province. I arrived in Lanzhou at around 5 a．m., but there were no buses to Xiahe. I managed to spot a policeman and attempted to explain my destination to him in simple English, praying that he would understand. I wasn't sure that he did but I just followed him anyway as I had no choice. He took me on a bus and I didn't know where I was going.Luckily, I met a student who explained to me in English that the policeman was taking me to another bus station where I could take a bus to Xiahe. During this conversation a third man said he was also a policeman and would help me buy tickets. But as he was not in uniform, I was a little doubtful.The uniformed policeman told me it was OK to go with the third man, so I got off the bus with the so-called policeman who, at this point, disappeared and I was left in the middle of nowhere. I stood panicking. Around one minute later a police car came and stopped right by me. It was the un-uniformed policeman. I got into the car and he dropped me directly at the bus station, and helped me buy the ticket.This is one of many experiences that I have had in China. I realized that however different this culture was, there was one thing that would always stand out—kindness. In the west we seem to lackthe foundation of trust, yet in China it seems that there will always be someone to answer your questions and lead you the right way.1．Which of the following is the closest in meaning to the underlined word “alien”？A．Unfriendly. B．Familiar.C．Strange. D．Attractive.2．What can we learn from the second paragraph?A．The author doubted the so-called policeman.B．The third man could speak English fluently.C．The author followed a student to another bus station.D．A police car took the un-uniformed policeman away.3．Why did the un-uniformed policeman disappear after the author got off the bus?A．He hurried to buy a ticket for the author.B．He went to get a car to pick the author up.C．The author didn't behave in a friendly way.D．The author found a uniformed policeman to help him.4．According to the text, what impressed the author deeply in China?A．Beautiful scenes.B．Terrible transportation.C．Troubles in small towns.D．People's kindness.Ⅱ.阅读填句When the music sounds, you immediately reach your pocket to have a chat. But have you ever stopped to think about the mannersrelated to talking on the phone？__1__Always give the person you are calling enough time to get to the phone before you hang up.__2__In this case, you should give your name and ask if you may speak to the person you want.__3__Phones must be turned off as soon as the plane doors are closed. And they remain turned off until the doors open again on arrival.__4__Finish any face-to-face business before taking a call. Continuing to use the phone while nodding to the person in front of you is quite impolite.If you go to a theater or a cinema, consider the other people around you. __5__If you are expecting a very important call, put your phone on “vibrate (振动) ”and run for the exit as soon as you feel it. If you forget both “off” and “vibrate” and your phone rings, don't answer it, reture it off straight away.A．It's impolite to make a phone call when you are having a meeting.B．Sometimes the person who answers is not the one you want.C．If you take a plane, remember to follow airline instructions.D．When face to face with someone, don't talk on the phone.E．Check that your phone is “off” before you enter.F．Stop using the phone if it disturbs the views.G．If not, here are some tips to guide you.Ⅲ.短文改错At Chinese New Year, my family and I have a very busy time. Two days before New Year's Day, I went out with my friends from school to the seafood restaurant in Pudong. It was the noisiestrestaurant which I had ever been to, and the food was cheap and delicious. After that, we went to shopping for new clothes and found lots of bargain. I visited my old teacher, Mr. Smith. For my surprise, he said he didn't find Chinese New Year very excited. He was even wearing new clothes! Because we have so many tests this week, I have to start studying hard again now. How I wish the holiday were long than ever before!答案Ⅰ.阅读理解出于对中国的好奇，作者独自来到中国旅行，并得到了中国警察和路人的热心帮助。

Ⅰ阅读理解A(2019·吉林长春七校高三第一次联考)Joseph Goldberger was a doctor for the United States Public HealthService and he was an advocate for scientific and social recognition of the links between poverty and disease. In 1914,Goldberger was asked by U．S. Surgeon General Rupert Blue to study a skin disease that was killing thousands ofpeople in the South. The disease was pellagra(糙皮病)．Goldberger traveled to the state of Mississippi where many people suffered from pellagra. He studied the victimsand their families. Most of the people lived a hard life. The doctor came to believe that the disease didn’t pas from one to another, but was instead related to food. He received permission from the state governor to test this idea ata prison. Prisoners were offered pardons if they took part. One group of prisoners received their usual foods, mostlycorn products. A second group ate meat, fresh vegetables and drank milk. Members of the first group developed pellagra. The second group did not.But some medical researchers refused to accept Goldberger’s idea. For the South, pellagra was more than simplya medical problem. There were other things, including Southern pride.So Goldberger had himself injected(注射) with blood from a person with pellagra. He also took liquid from thenose and throat of a pellagra patient and put them into his own nose and throat. He even swallowed pills that containedskin from pellagra patients. An assistant also took part in the experiments. So did Goldbe rger’s wife. None of them gotsick.Joseph Goldberger died of cancer in 1929. He was fifty-five years old. Several years later, researchers discoveredthe exact cause of pellagra：a lack of vitamin B3 known as niacin.【解题导语】本文是一篇记叙文。
