This reason comes from the early 20th century. At that time, shellac records(虫胶唱片) first appeared. Its volume was very small. The most popular record could hold about three to five minutes for music on each side.The late 1940s saw the birth of the smaller, cheaper vinyl record(黑胶唱片). It could hold no more than three minutes of music each side. Musicians wanted radio stations to play their music, so they had to use this time limit.After that, music technology developed from records to tapes to CDs. But three-minutes pop songs didn’t fall out of time. There were a number of r easons for this. Radio stations could put more advertisements into a program if the songs stayed short. Pop music listeners also got used to listening to shorter songs.Today, more and more people listen to pop songs online. The success of a song is now less about its sales but more about its numbers of plays. As a result, many song writers fill their works with short songs. They want people to play more songs each time. This is what they need.1题完成句子，2-3题简略回答问题，4题找出并写出全文的主题句，5题将文中画线句子翻译成汉语。

We always seem to think that there are an endless number of them. Is this true? Will we run out of fish one day?Humans began overfishing the world’s oceans in the 19th century. Today, there are enough fishing ships in the world to catch four earth’s worth of fish. In other words, we are taking away too many fish from the world’s oceans. The fish stock(鱼群) can’t grow back fast enough. So, the numbers of many kinds of fish are dropping sharply. Some kinds will soon be in great danger.To save these fish kinds, many areas have started to do something. Near some rivers andlakes, you will see “No fishing” signs. The fish in these areas are probably under protection. Besides, there have been closed fishing periods at different times in different areas. When the fish in a certain area start to lay eggs, the closed season for that area begins. People can’ t catch fish until the young fish grow up. This is also an important way to stop overfishing.All life of the living things here depends on the sea. And fish are very important to the health of the sea. Let’s work together to protect our friends in the water.1~2题完成句子，3题简略回答问题，4题找出并写下第三段主题句，5题将文中画线句子译成汉语。

Everyone thought that he would be the most important person in the world.But the second young man, Tom, was different. He always took a heavy responsibility(责任).One day, bad things happened and they met many problems. John didn’t know what to do. But Tom tried his best to solve the problems. He thought of some good ways and didn’t let the bad things affect(影响) the people in the town.

We may hear of many stories about how dolphins save people out of water.Dolphins often eat fish and some other sea animals. A dolphin with a weight of 200kg to 250kg will eat 10kg to 25kg of fish every day. They like to swim with other dolphins and usually hunt(捕猎) in groups.Dolphins have very good hearing. They use it to find things under the water. Many scientists also believe dolphins can even talk to each other through a special whistle(哨声). People from different areas(地方) don’t speak the same language. Just like people, dolphins’ whistles have many kinds. One day we may understand dolphins’ whistles, and then they will be able to tell us about themselves.Dolphins live in the sea, but they are not a kind of fish and they don’t lay eggs. They have babies in the same way as cows and cats do, and give their babies milk. A female dolphin has a baby every two to three years.Dolphins are very friendly. Sadly, there are not many kinds of dolphins left. Peoplekilled them for many years for food and other things.

In the UK, most children have their lunches at school, but in some schools, parents can choose what their children eat. The children can have a sc hool dinner — a hot, cooked meal; or they can take a packed lunch with them, which usually includes cold food like sandwiches.Often parents know what their children want. Cathy, a mother of three children, told us, “My children have packed lunches because they say they hate s chool dinners. So I make three packed lunches every morning.”However, another mother, Susan, made a different choice. She said, “My daughters have always had school dinners. I think they probably get healthier food at school than a few sandwiches I make for them.”But are school dinners healthy? Katz, a father, thought poorly of them. He said, “Fizzy drinks (汽水) were offered and I think there were lot of chips.”Jamie Oliver spent a year working in a school kitchen. He was worried about the unhealthy food which included burgers, pizzas and chips. So he tried t o cook healthy food such as good stews（炖汤） and curries（咖喱） for the children instead.So Janie improved the school dinners, and trained the dinner ladies to cook healthy food in that school. Then he advised the government to improve sch ool food across the country. And it seems that the changes have begun.Anna, a pupil, told us, “we used to have a fast food window where you got chips and coke, but they stopped that this year. There’s salad restaurant, whi ch is good, so it’s healthier than it was.”【小题1】_______ would like the children to have the school meals.A．Katz B．Jamie C．Cathy D．Susan【小题2】How many meals do most children in the UK have at school?A．One B．Two C．Three D．Four【小题3】Jamie thought ______ were healthy foodA．stews and curries B．sandwiches and cokeC．chips and fizzy drinks D．burgers and pizzas【小题4】The last two paragraphs show that________.A．There’s a salad restaurant in every school B．salad is the only healthy food for studentsC．schools have begun to cook healthier food D．the government doesn’t care about school dinners【小题5】What is the best title for this text?A．Healthy Food B．Unhealthy FoodC．School Dinners D．Packed Lunches18. In some Western countries, many children do chores to get pocket money. They usually start to do this when they are ten years old.School students have to do homework and study for tests. They don’t have much free time on weekdays. They often do chores on weekends.Young kids only do easy chores. So they don’t get much money. But that’s enough. Many of them only want to buy candy. And candy is cheap! They o ften help do the dishes, sweep the floor, or feed the pet cat or dog.When they get older, they want to buy more and more things. They want things that are more expensive than candy. So they have to work harder! They often help their parents wash the family car, cut the grass, or cook meals.Some jobs are a good way for kids to learn new things. For example, they can learn how to use a lawnmower (割草机) or how to cook. Of course, their parents help them at first.【小题1】How do many children get pocket money in some Western countries?A．They ask their parents for it.B．They do part-time jobs.C．They do chores.D．They study hard.【小题2】When do many children usually begin to do chores in some Western countries?A．At the age of 15.B．At the age of 13.C．At the age of 10.D．At the age of 17.【小题3】Mary wants to get more pocket money to buy something expensive.

Trash and garbage are other words for waste things that people no longer want or need. In San Francisco, they are also words for art. A local recy cling（资源回收利用） company created a program to make artists reuse unwanted objects. Artists are paid to work for four months on transforming (转化) things like old tires, toys and paint.Ma Li is one of the artists at the center. She is working on a project that includes plastic bottles and cloth. She is turning them into a moving sculpture （雕塑） with stars, flowing hair and dancers. Ms Li says she learned recycling from her parents while growing up in China in the 1980s. It was a time whe n the country was poorer and more concerned about saving money than it is today. A gallery（画廊） in Los Angeles is showing some of the art from San F rancisco project. Each year more than 5,000 children and adults visit shows created by the artists.Mike Sangiacomo controls the recycling company. He says he hopes to see as much waste as possible reused. “Along the way, if some of it is made int o some fun pieces of art and draws(吸引) people’s attention to the issue（问题）, we think it’s a great way to do something that’s good for our society.”And the project shows how a little imagination can change one person’s trash into another’s art work.【小题1】The following three has the same meaning EXCEPT________.A．trash B．garbage C．waste D．resource【小题2】Which of the following can be called garbage?A．Eggs.B．Tires.C．Toys.D．Broken glass.【小题3】When a good person is poor and concerned about money, then he may________.A．waste things B．steal money C．recycling things D．buy gold【小题4】Where are the arts shown that are made by Ma Li?A．In Washington.B．In Los Angeles.C．In Son Francisco.D．In China.【小题5】Which statement is RIGHT according to the passage?A．Ma Li makes the sculptures for free.B．Ma Li’s parents used to waste a lot of things.C．Waste things can never be reused.D．Recycling is good for environment.四、多任务混合问题20.

The flower is really big. Its color is red. Look closely, and you can find that it has teeth. It is called Rafflesia. It is the world’s largest flower. You can see it in the documentary The Green Planet.The Green Planet is a new documentary from BBC．It shows us the world of plants. To find different plants from the world, the film workers travelled from the rainforest to some snowy places. They also climbed mountains and walked into deserts. To find plants in the water, they even jumped into rivers.

初二上册Module 1Unit 1 让我们尽可能多地讲英语同学们，欢迎回来！今天，我们打算谈论一下学习英语的好方法。

准备好了吗？谁有一些建议?在课堂上我们应该总是讲英语。

好！让我们尽可能多地讲英语。

为什么不在我们的笔记本上记下错误呢？那是个好主意，而且不要忘记在错误旁边写上正确的答案。

还有其他的什么吗？每天大声拼读生词是一个好主意。

非常感谢你，玲玲。

听广播怎么样？是的，那也有益于我们的发音。

但有很多生词。

你们不必理解每个单词（的含义）。

你们只需要听关键词和主要意思。

阅读也一样。

英语故事如此有趣。

通过阅读我逐渐了解了世界上的许多事情。

我认为写作也很重要。

我们为什么不尽量去找些讲英语的笔友呢？我们可以给他们写信。

太棒了！我同意你（的提议）。

Unit 2 你应该向她微笑！很多学生咨询如何提高他们英语水平的建议。

这儿是三个基本问题。

第一个问题是关于理解英文电影和歌曲的问题。

来自湖北的李浩写道：“我喜欢看英文电影，听英文歌曲，但我只能理解一点儿。

我可以怎么做呢？”看电影和听歌曲是学习英语的很好的方式！看上或听上几遍，并猜测生词的含义。

每一遍你都会学到新东西。

我还建议你和朋友们谈论一下这些电影或歌曲。

第二个问题是关于说的。

来自吉林的王帆写道：“我们学校有一位来自美国的老师。

我很腼腆，不敢与她说话。

我该怎么办呢？”你可以说：“嗨！你好吗？”“你喜欢中国吗？”这些都是展开交谈的好方式。

在你开始（讲英语）前，你应该向她微笑！记住这一点：不要害羞，去试一试。

第三个问题是关于词汇的。

来自安徽的张雷写道：“我写下生词，但我很快就忘记了它们。

我怎样才能记住它们呢？”不用担心，忘记生词是很自然的！我建议你每天把4个或5个单词写在纸片上并放在你的房间里。

看到这些单词的时候就读一读，并且尽量使用它们。

Module 2 我的家乡和我的国家Unit 1 它比许多其他建筑物都高。

嘿，大明！你的周末过得怎么样？很好！我去深圳了。

深圳在哪儿？哦，它在靠近香港的海岸线上。

That’s especially true if someone in your family has it. A virus can cause stomach flu, but not the same one that causes common flu. There’s no medicine t o make it go away at once. But there are some things you can do to stop catching it.You can stop stomach flu by washing your hands often. Use hot water and soap to wash your hands. Using soap is better than using nothing, but it doesn’t work very well against stomach flu. That’s because soap can’t kill virus completely.The virus that causes stomach flu is hard to kill. Normal cleaners(清洁剂) won’t always get rid of it. So mix bleach (漂白剂) with water, and use that to clean your house. If someone in your family is sick, remember to clean things that person has touched.Dishwashers are better at killing viruses than washing the dishes by hand. That’s because they keep the dishes hotter or longer. Many viruses can live in your washing machine. So wash clothes with hot water and use bleach, if possible. You may even run the washing machine with no clothes, just hot water and bleach. This will kill any virus in it.If you do get the stomach flu, drink as much water as possible. If you’re feeling better, don’t ret urn to work or school right away. You can still spread the disease for a few days after you feel better. If you have a fever, wait at least 24 hours after it ends before going out. This will help stop other people from getting sick.Stomach flu is awful, but by following these tips above, you can keep away from it.31. From paragraph 1, we know that ________.A．stomach flu is a pleasant common flu.B．medicine can make stomach flu go away at once.C．if someone around you catches stomach flu, you may catch it, too.D．the same virus can cause stomach flu and common flu.32. What does the underline phrase “get rid of” probably mean in paragraph 3?A．逃离B．除去C．避免D．变糟33. Which of the following is the best to kill viruses?A．Washing your hands with water and soap.B．Mixing bleach with water to clean your house.C．Washing the dishes and clothes with bleach by hand.D．Running the washing machine without clothes, just with hot water and bleach.34. What should we do after a fever ends?A．Take as little medicine as possible. B．Return to work or school at once.C．Wait at least 24 hours before going out. D．Go to see the doctor again.35. Which of the following shows the structure of the passage?A．B．C．D．According to Lu Yu’s Tea Classics, Chinese began to drink tea in the Zhou Dynasty. Shennong discovered tea and it became popular as a drink in the State of Lu because of Zhou Gong.Tea-drinking in China has a history of four thousand years. As the legend has it, Shennong tasted hundreds of wild plants to stop people from eating the poisonous(有毒的) plants. It is said that he has poisoned seventy-two times in one day but he got better by eating some leaves of an evergreen plant with white flowers. Later, people called the leaves “cha”.In modern times, tea can also have effects on some modern illnesses. If people have to work with computers for a long time, drinking tea can help them to build up a wall against the computerradiation(辐射). If people have too much fat, drinking tea can help them to recreate a new balance in their bodies. And if people are over 60 years old, drinking tea is also a good way to keep calm for a longer life.1—2题完成句子，3题找出并写下第三段的主题句，4—5题简略回答问题。
