Let’s have a look at what we laugh at in 1 .To us British people, 2 and important people often cause laughter. It’s not just politicians(政客) who make us laugh, but anyone whose job is to tell other people what to do and who takes 3 too seriously.We laugh at the power, but also, pitifully, at anyone who is treated 4 . We know they cannot win, but if they do win sometimes, it’s even 5 . Our clown(小丑) are often silly people doing silly things, while in America, they are often clever people doing clever things—and 6 at last.The fact that we laugh when other people might feel 7 is one of the strangest things to learn about British humor. We do have a strong sense of irony(反讽) . After some terrible experience, we might say, “Not very 8 .” And we might say in the middle of a typhoon, “It’s a bit windy today.” Or “There is a tiny problem.” when something has gone 9 wrong. We don’t like to express strong feelings, but just “keep calm and carry on”.Another thing that can make it difficult 10 British humor is that we don’t always laugh or even smile when we say something funny. We often keep a straight face or use an unsmiling expression when we’re making a joke.Do you think the British sense of humor is special?1. 2. 3. 4. 5.6. 7. 8. 9. 10.2018but, choice, color, direct, fly, high, important, instead, it, many, quick, slowOne day, a father and his son went to a kite flying festival. When they arrived,there were already many adults and their children playing in the park. When theson saw the sky filled with 1 kites in different shapes, he was excited andwanted to get one too. His father agreed to buy one for him. So they went to a kiteshop and 2 a beautiful one.With the string(线)in hand, the son started 3 the kite. Soon, the kite was high up in the sky. After a while, the son said, "Father, it seems that the string is stopping the kite from flying higher. If we cut it, it will be free and fly even higher. Can we cut it?” The father didn’t reply, but just cut the string off the reel(线轴). Suddenly, the kite began to go 4 , which made the son much happier.However, to his surprise, the kite was coming down. They waited for quite some time. 5 , it fell onto the grass. The son felt upset and asked, "I thought that after cutting the string, the kite would fly higher.Why did it fall down?”The father smiled and said, “The role of the string was not stopping the kite from flying higher, 6 helping it stay in the sky, because the kite 7 can' t fly up. By using the string you help the kite go up in the right 8 . When you cut the string, it could not support the kite.In our life, we may sometimes feel like there are certain things that are holding us back and stopping us from growing. But in fact, these might be the things that support us_ 9 . We can really grow up and2017An old saying goes, "When in Rome（罗马）, do as the Romans do." I learned the 1 of this when I studied in Russia.One day I invited some of my Chinese friends to a famous local restaurant in Moscow. My guests and I were 2 from visiting Red Square and happy about our meeting. We had a warm chat until the waiter told me that we were being too loud. We turned our voices 3 . But this didn’t last long. The waiter came over to us two more 4 with the same message.How bad an impression（印象）we must have left on the local people! In China, it’s 5 and important for a host to make a 6 atmosphere（气氛）. However, in Russia and 7 countries, having a meal in a public place means you must keep your voice low. You need to be polite to others.I felt bad about this. Even though we tried our 8 , it’s very difficult to develop a new habit. Russians have their own special habits. My Russian friend, Andrey always looks around and thinks for a while before leaving home. I asked him why he did this. “Aha,” Andrey said, “in Russia, people always take about a minute 9 over things and plans in their minds before leaving. So they won’t leave anything necessary behind.”2016A boy thought that he was the most unhappy person in the world. He thought he was 1.________ because almost everything bad always happened to him. So he wanted to find the key to happiness. He walked a long way and finally came to a 2._______ palace. There, he met the king.After learning why the boy had come, the king advised that he should look around the palace and come back in two hours. “At the same time, I want you to 3.________this spoon with milk,” said the king. “Asyou walk around my palace, carry this spoon without spilling(溢出) the milk.”The boy kept his 4. _______on the spoon and began to walk around the fantastic palace. After two hours, he came back to the king. “Well,” asked the king. “Did you see the wonderful 5._______ in my dining hall？Did you see the 6._______ flowers in the garden? ” The boy felt sorry because he only paid attention to the milk.“Then go back and see the beauty of 7. ________ world,” said the king. This time the boy saw all of the 8.__________of art on the walls. He saw the greatest gardens and mountains all around. When he came back, he described everything he saw.“But where is the milk?” asked the king. Looking 9.________ at the spoon he held, the boy saw the milk was 10.________. “Well, the key to happiness is to see all the beauty of the world and also keep an20152014Look at the picture, what do you see? 1 , some people say it’s an old man,while others say it’s a young woman and an old 2 . It is a problem with manyanswers. Why? When you look at a problem from different views, you get differentanswers. Just turn it in your mind 3 bit, and you may see it in a completely newway.Some people only form an idea in their mind “A problem has only one answer, and allthe 4 are wrong.” Some even laugh at the different answers others come up with.Well, they’re wrong! If people only believed in one answer, we might still think theworld is square(方形的)! What’s one plus one? That’s easy, two! Right? Well, that’s oneright answer, but not the only answer. You might think of 11, or some 5characters like “二” or “十”! What’s a mom plus a dad? You might think of two people, or a man and a woman, or a whole family! So, even the 6 questions can have many answers. Of course, some problems do only have one answer. If each of the questions in a math test had 7 than one answer, it would be quite a problem for teachers 8 . Look at things in different ways, face your life with a 9 mind, and you’ll see a completely different world.

You pass a group of people. The people are talking to each other. You cannot hear what they are saying. But 1 they start laughing. What would you think? Would you think they were laughing at something 2 that one of them said? Or, to be honest with yourself, would you think they were laughing at you? Yes, you.Being laughed at is a 3 fear. But a major study published(公布)in 2009 found that this fear is not the 4 around the world, It differs from culture to culture.Some people in the study said they felt unsure of 5 in social situations and hid their feelings of insecurity (不安全). Others said they avoided (回避) social situations where they had been laughed at 6 .Shy people often avoid situations that would make them get into close contact (接触) with other people. They worry that something they say or do will make other people laugh at them, It can be truly sad for those who live with the fear of laughter. It can 7 how they lead their lives.In the study, a team from the University of Zurich led more than ninety 8 from around the world.

The scientists surveyed more than twenty-two thousand people in forty-two different languages. The 10Once there was a teacher who took all his students for tea. What made the students 1 was that all the cups on the table were 2 . Each of them took a cup and started 3 their own tea, looking at the 4 cups.The teacher said; "Do you notice your 5 ? You are all looking at each other's tea cups and 6of you even envy (羡慕) the 7 cups of others." Then he went on: "I put the different cups here on purpose! Life is like 8 tea. You all have the same thing in your cups— tea. And yet you can't 9 enjoy it in your envy of another's cup. You forget 10 your own life when you envy someone else's life. So now, taste your own tea!

2020届中考语文全程训练 课后刷题本12 现代文阅读-说明文(10篇含答案)
2020届中考语文全程训练课后刷题本12现代文阅读-说明文1.阅读下面材料，完成下列小题：中国适合走向“汽车社会”吗？①2009年，中国以1300多万辆汽车首次超越美国，成为世界汽车产销第一大国。
中国人虽然理应享受汽车文明，但中国不可能像西方国家那样，达到那么高的汽车拥有率。
原因如下：②第一，土地制约。
城市街道交通拥堵，不少街道两侧摆满了车，远远看去就如一条长龙，不少住宅区、公共绿化带等也都成了“停车场”。
中国已占用了太多的良田、林地、草原用于新建、扩建公路。
占地面积数量大的高速公路通车总里程已突破5万公里，相当于美国的近60%；而占地面积相对较少的铁路总里程仅有8.4万公里，只相当于美国的1/3。
这说明中国交通发展向汽车倾斜的程度超过了美国。
③第二，能源制约。
美国的汽车普及率已超过．．50%，如果中国的汽车普及率达到美国的水平，到2020年预计中国将有6.9亿辆汽车。
若以每辆汽车每年平均耗油2吨来计算，中国的总耗油量将达13.8亿吨，相当于目前全球每年石油贸易量的86%。
这可能吗？即使普及电动汽车，也只不过是改变了使用能源的种类。
中国超过70%的电能来自化石燃料中最具污染力的煤，这种状况在今后相当长的时期内也难以改变，电动汽车的普及不可能明显缓解能源的制约。
④第三，环境制约。
汽车尾气排放正在成为最大的污染源。
如果今后二三十年中国的汽车普及量达到6.9亿辆，就意味着未来废气排放量相当于当前世界所有的汽车排放的总和。
⑤受土地、能源、环境这三大因素的制约，中国是否适合做一个“汽车轮子上的国家”呢？（1）中国汽车拥有率低于西方国家的原因是什么？（2）文中第②段画线句运用了什么说明方法？有何作用？（3）文章第③段中加点词语“超过”能否删除？为什么？（4）为了让中国尽快走向“汽车社会”，你能提出哪些合理化建议？2.阅读下面材料，完成下列小题：【材料一】梦的解析梦，也有梦想的意思。
古人相信，做梦总要有原因的，王符就曾说“夫奇异之梦，多有收而少无为者矣”，他认为做梦总有原因可寻，正所谓“日有所思，夜有所梦”。
