1．　　Why do people wear clothes? "To make me warm and (1)       my body" will probably be the answer. That's why people wear clothes, but people also want to look attractive and appear (2)       to others.
　　If clothes (3)       for warmth and to cover their bodies, most clothes will be simple and cheap. In many countries, however, clothes are sometimes very expensive. The main reason (4)       this is not the cost of the materials or the cost of making clothes. The clothes are expensive (5)       they are fashionable.
　　Successful businessmen, for example, often wear very expensive suits, shirts and ties. So they pay (6)       dollars for a suit and several hundred dollars for a tie. It's still just a suit and (7)       tie, but they pay these prices because of the famous designers.
　　Fashion (8)       constantly (持续不断地). It means that people (9)       want to be fashionable have to buy new clothes every few months, even if last month's clothes have only been worn once or twice. Some people have (10)       many clothes that some of these clothes have never been worn. These clothes are no longer in fashion though they are still new.

2．　　High school does not encourage students to know about the new things in life, but college sets the stage for it. I myself went through this (1)       process (过程) and found something that has changed my experience at college for the better: I discovered ASL-American Sign Language.
　　I never felt it necessary to learn any sign language before. All of my family members can hear, and so are all my friends. The (2)       language was enough. Little by little, I discovered my (3)       for ASL.
　　The (4)       began during my first week at college. I watched it carefully when the ASL club performed their translation of a song. Both the hand movements and the idea of communicating without speaking attracted me. What I saw was completely different from anything I had experienced in the past. This new form of communication just made me want more.
　　After that, feeling the need to (5)       further, I decided to join one of ASL clubs. I only learned how to (6)       my feelings with my hands about the letters that day. Although my process was (7)      , I wasn't disappointed about it. I then tried my best to take part in those clubs' meetings and learned all I could.
　　The following term, I decided to be a member of an ASL class. The professor was deaf and any talking wasn't (8)      . I soon realized that silence was not unpleasant. (9)      , if there had been any talking, it would have caused to learn less. Now, I enjoy the silence and the (10)       way of communication.

3．　　The policeman slowly walked along the street. It was barely ten o'clock at night. The wind and light rain had kept most people at home.
　　Halfway down the street, the policeman saw a man leaning against a door, with an unlighted cigar in his mouth. As the policeman walked up to him, the man spoke quickly. "It's all right, officer," he said. "I'm just waiting here for an old friend. It's an appointment that was made twenty years ago. You think it funny to plan a meeting like this, don't you?"
　　The man lit his cigar. The light showed a pale, square-jawed face with keen eyes. He was very well-dressed.
　　"Twenty years ago tonight," the man went on, "I dined at a restaurant nearby with my friend Jimmy Wells. I was going to the West to try my luck, but Jimmy wanted to stay. We agreed to meet here again exactly twenty years form that date and time. That's why I'm here."
　　"What happened to your friend?" asked the policeman.
　　"I'm not sure," said the man. "We wrote to each other for a while and then stopped. But I'm sure if he is alive, he will keep his promise. We said we would meet at ten o'clock."
　　"OK, I'll be on my way. Good night."
　　The policeman continued on his way; Bob waited about twenty minutes. Then, a tall man went straight to the waiting man.
　　"Is that you, Bob?" asked the newcomer.
　　"Is that you, Jimmy?" cried the man in the door. "You've grown so tall. Let me have a good look at you. You don't look anything like Jimmy." "You're right," said the tall man. "I'm a police officer. You are wanted by the New York police. But, before we go to the police station, here's a note from your friend Jimmy Wells."
　　Bob opened the small piece of paper. His hands shook as he read.
Bob,
　　I was on my way to meet you as we had planned. However, when you lit your cigar, I saw it was the face of a man that is wanted by the police. Somehow, I couldn't do it myself. So I sent another police officer to do the job.
Jimmy

4．　　Perhaps no one knows the power of imagination better than Chinese sci-fi writer Liu Cixin. Until four years ago, Liu worked full-time as a computer engineer at a power plant in Shanxi province. He only wrote science fiction in his spare time. But it was during this time that Liu's imagination took flight. He did what he might never have the chance to do in real life — wander in space, fight with aliens, and visit far away planets.
　　But even with such a powerful imagination, Liu, 55, probably didn't expect that he would become the first Asian to win the Hugo Award, science fiction's highest prize, in 2015. Never did he think that former US president Barack Obama would read his novel The Three-Body Problem, and he would win the 2018 Arthur C. Clarke Award for Imagination in Service to Society. It's the first time that a Chinese writer has won the prize.
　　In his speech, Liu said that his imagination came from Arthur C. Clarke, a famous UK sci-fi writer. He said that reading Clarke's classic novels had a great effect on him.
　　But no matter how far away Liu's imagination takes him, somehow his novels always stay grounded (理性的).
　　In The Three-Body Problem, Liu tells a tale of aliens invading the earth. But unlike other alien stories, Liu talks more about relationships between people, rules of survival, and the meanings of life. And in The Wandering earth, Liu looks ahead to the day when our solar system comes to an end and humans have to look for a new place to live in. However, all his imagination is based on reality. Liu's works aren't simply daydreams.

5．　　To sum up history in one sentence, it would be "Life gets better — not for everyone all the time, but for most people most of the time. " And the reason is energy. Without access to energy, poor people are stuck in the dark and deny all of these benefits and opportunities that come with power. For thousands of years, people burned wood for fuel and their lives were hard. But when we started using coal in the 1800s, life started getting better a lot faster. Pretty soon we had lights, refrigerators, elevators, cars, planes, and all the other things that make up modern life. So if we really want to help the poor, we need to find a way to get them cheap and clean energy.
　　Millions of the poorest families work as farmers. Changes in climate often mean that their crops won't grow because of too little rain or too much rain. That's particularly unfair because they're the least responsible for emitting (排放) CO₂, which is causing the problem in the first place.
　　Scientists say that to avoid these great long-term changes to the climate, the world must cut greenhouse gas emissions by up to 80 percent by 2050, and eliminate them completely by the end of the century. Many scientists agreed that wouldn't be enough. The problem is that CO₂ lingers (残留) in the atmosphere for decades.
　　In 2015, the world emitted 36 billion tons of CO₂ to produce energy. Someone may tell you they know how to remove 100 million tons of CO₂ per year. That sounds like a lot, but if you do the math 100 million divided by 36 billion you'll see that they're talking about 0. 3 percent of the problem.
P × S × E × C =CO₂
(P — world's population; S — services used by each person; E — energy to provide service, C — carbon dioxide produced by energy)
　　As you learned in math class, any number multiplied by zero will equal zero. So if we want to get to zero CO₂, then we need to make at least one of the four factors zero. But the world's population(P) is currently 7 billion and expected to increase to 9 billion by 2050. In terms of services used by each person(S), there are a lot of things like food, living, transportation and so on, which means the need of much energy in providing them. Therefore, it is carbon dioxide produced by energy (C) that matters the most in cutting down CO₂.

6．　　Throughout the history of arts, the nature of creativity is important to artists. No matter what objects they select, artists are to bring forth new forces and forms that cause change — to find poetry where no one has ever seen or experienced it before.
　　Landscape (风景) is another unchanging element of art. It can be found from ancient times through the 17^th-century Dutch painters to the 19^th-century romanticists and impressionists. In the 1970s Alfred Leslie, one of the new American realists (现实主义者), continued this practice. Leslie found the same place where Thomas Cole, a romanticist, had produced paintings of the same scene a century and a half before. Unlike Cole who insists on a feeling of loneliness and the idea of finding peace in nature, Leslie paints what he actually sees.
　　In his paintings, there is no particular change in emotion, and he includes ordinary things like the highway in the background. He also takes advantage of the latest developments of color photography to help both the eye and the memory when he improves his painting back to his workroom.
　　Besides, all art begs the age-old question: What is real? Each generation of artists has shown their understanding of reality in one form or another. The impressionists saw reality in brief emotional effects, the realists in everyday subjects and in forest scenes, and the Cro-Magnon cave people in their naturalistic drawings of the animals in the ancient forests. To sum up, understanding reality is a necessary struggle for artists of all periods.
　　Over thousands of years the function of the arts has remained relatively constant. Past or present, Eastern or Western, the arts are a basic part of our immediate experience. Many and different are the faces of art, and together they express the basic need and hope of human beings.
