April 22 is Earth Day. Everyone on Earth should care about and protect the earth!
The earth has warmed by about 1°F (华氏度) over the past 100 years, but why and how?
Well, scientists are not quite sure. Maybe the earth gets warmer and warmer on its own. But many scientists say that people are doing many things which makes the earth warmer.
First, greenhouse effect (温室效应) is a very important reason for the change of the earth. People give out too much energy into the air every year. It makes the earth warmer. Climate (气候) change is another important reason. Sometimes it becomes too hot and sometimes too cold. Sometimes there is too much rain and sometimes too little. The change of the climate makes the earth warmer. In turn, the warmth of the earth changes the climate, too.
When the earth becomes warmer, there may be more rain and a rise in sea level. It will affect the growth of plants, animals and people. On a Pacific island, 100 people have to move to higher ground because the sea is rising. These people can no longer live on the coast. Before that, two islands without people went underwater in 1999. Scientists say that the seas can rise by nearly one metre by 2100.
People can affect the earth's air, land and water. As for us, we can do many things to protect the earth. For example, we can use fridges less. We can tell more people about protecting the earth.Earth Day is probably set for people to ______.
| A．learn more about the earth | B．make full use of the earth |
| C．take better care of the earth. | D．study the warmth of the earth |
We can infer (推断) from the passage that the reasons for the warmer earth are
______ now.
| A．not very clear | B．completely secret | C．well known | D．not given yet |
Greenhouse effect comes from______.
| A．sea rising | B．climate change | C．nature's unbalance | D．people's activity |
The passage mainly tells us that ______.
| A．there is more rain now | B．we should protect the earth |
| C．we must stop pollution | D．sea level is getting higher |
Life in the future will be different from life today. Between then and now many changes will happen. But what will the changes be?
The population(人口) is growing fast. There will be many people in the word and most of them will live longer than people live now.
Computers will be much smaller and more useful. And there will be at least one in every home. And computer studies will be one of the important subjects in school then. People will work fewer hours than they do now and they will have more free time for sports, watching TV and traveling. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.
There will be changes in our food, too. More land will be u sed for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat meat every day. Instead they will eat more fruit and vegetables. Maybe people will be healthier.
Work will be different in the future, too. Robots will do dangerous and hard work. Because of this people will not have enough work to do. This will be a problem.In the future there will be__________.

In classroom, your teachers will talk about topics that you are studying. The information they provide will be important for you to know when you take tests. So you must be able to take good written notes from what your teachers say.
Here are the three stages(阶段) of taking notes and what you should do during each stage.
1. Before Class
Review your notes you have taken before you come to class. This will be good for remembering what was covered. Get you ready to understand new information your teacher will provide.
2. During Class
Keep your attention on what your teacher is saying and “the signal words” that tell you what your teacher is going to say and it is important to write in your notes. Examples of signal words are “The most important point…” and “Remember that…”. Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations such as med for medicine, using symbols such as % for percent, and writing short sentences.
3. After Class
Rewrite your notes to make them more complete and accurate(准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.

Do you see many signs around you? Do you know the signs are an important part of our daily life? They can be in pictures or in words to give people information. What do people think are good signs? If you are thinking about making signs for others, what should you know?
The most important thing is that signs should be simple and easy to understand. It is important to use clear language. On the other hand, the words should be easy to write and you just need to write down what you want to do. “Keep off the grass” is a very good example. It means “Don’t touch or walk on the grass”.
Nowadays, there is a saying that “A picture paints a thousand words”. Perhaps that’s why we are seeing more and more signs in pictures, or a combination of pictures and words. However, that’s the difficult part, because picture signs may have different meanings in different countries. First, a good sign should be ____.
| A．clear | B．beautiful | C．funny | D．interesting |
The writer uses “A picture paints a thousand words” to show that ____.
| A．a word sign is as easy as a picture sign to make |
| B．a picture sign often has more information than a word sign |
| C．a word sign has more information than a picture sign |
| D．a word sign and a picture sign have the same information |
What does the underlined word “combination” mean?
| A．分开 | B．结合 | C．并列 | D．平行 |
What’s the best title of the passage?
| A．Word Signs | B．Picture Signs |

We know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration (迁移) is probably the migration of fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently (近来), scientists have studied the migration of a kind of lobster (龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don’t. Maybe living things just like to travel.Most animals move from one place to another at a certain time to _______.
| A．give birth | B．find food more easily |
| C．enjoy warmer weather | D．find beautiful places |
The mice in northern Europe move when _______.
| A．they give birth |
| B．they haven’t enough food |
| C．the weather is bad |
| D．the place gets too crowded |
What is the main idea of the passage?
| A．Animals move to find food more easily. |
| B．The migration of the fish called “salmon” is the most famous migration. |
| C．Sometimes we know why and how living things move from one place to another, but sometimes we don’t. |
| D．Living things move from one place to another because they like to travel. |
