Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo(竹子) . Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied(多样化) diet . The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

The leaves start changing color when the nights start getting longer and the temperature starts getting cooler. Some scientists think that as the number of daylight hours shrinks, the leaves stop making chlorophyll which makes plants green. The reason is that the process of making chlorophyll requires sunlight. But according to horticulture (园艺) educator Susan Rose from Colorado State University, it turns out leaves don’t really change color at all. “The fall colors are actually there all along,” she said. “But they are covered by the green chlorophyll. As the chlorophyll stops being produced, the other colors can shine through.”
The kind of color that the leaves are going to change to is determined by the plant’s genetic (基因的) background. In some places, the leaves start changing color in September — before autumn even officially begins. In other places, they don’t change until late October or even November. Some scientists say the leaves have been changing color later than usual in recent years. And they think global warming has something to do with that.
In one study, researchers found that the growing season in the Northern Hemisphere was nearly a week longer, on average, in 2008 than it was in 1982. And a professor from Harvard University found that the leaves, west of Boston, Massachusetts, are changing color about three days later than they used to. However, other scientists disagree with the global warming theory. Susan Rose said the leaves in her part of Colorado are changing “right on schedule.” But the leaves in other parts of that state are running a little late. “The lateness in the mountains may have something to do with the really warm late summer and early fall,” she said. “But I’m afraid that’s just a guess.”
小题1:According to Susan Rose, _____.
| A．the fall colors are always in leaves |
| B．leaves make chlorophyll all the seasons |
| C．leaves’ changing color have nothing to with the weather |
| D．leaves begin changing color because they start making chlorophyll |
| A．reduces | B．increases | C．lasts | D．appears |
| A．genetic background | B．dry weather |
| C．global warming | D．low temperature |
| A．why leaves change color at fall |
| B．leaves change color at different time |
| C．the effects of the global warming on plants |
| D．different opinions on the lateness of leaves’ changing color |
Some things we send into space fall back toward the earth and burn up in the atmosphere. But larger pieces sometimes survive the extreme heat and hit the ground or the ocean at great speeds. So there is always concern that something may fall from the sky and do some harm.
But space junk falling on housetops (屋顶) is not the biggest worry. Scientists are concerned about what happens when an empty rocket strikes another while orbiting (绕轨道飞行) the earth. Two big things become many smaller things. They then hit other things. The pieces get smaller and smaller until they form a cloud of junk that blocks the path of future space vehicles.
So what can be done to clean up the space around our planet? Marco Castronuovo, an Italian researcher, talks about sending a satellite into space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the atmosphere.
Mr. Castronuovo has proposed (提议) using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite would jump from one large piece of junk to another. He thinks this method could destroy about ten large objects each year.
Scientists have been concerned about space junk for many years. Right now, the costs of the clean-up have been too great. Mr. Castronuovo says his system could be put in place for a much more reasonable amount of money.
小题1:Much of the space junk _____.
| A．was thrown by the astronauts |
| B．is from broken spaceship |
| C．is made up of small pieces of things |
| D．returns to the earth piece by piece |
| A．will stop the future space vehicles |
| B．will do harm to the atmosphere |
| C．will fall on the housetops |
| D．will burn up in space |
| A．It can remove space junk completely. |
| B．It can save a large amount of money. |
| C．It can create a large amount of space. |
| D．It can develop robotic technology. |

One of the most important and basic lessons in dealing with a foreign language is to learn and understand each concept and lesson before moving on to the next one. If you don’t understand one concept but move on to the next chapter anyway, you’re less likely to understand the new material.
Learning a new language is not only an academic tool, but can help you in your everyday life as well. Being good at another language can help you communicate with other people, and help you when traveling to foreign countries, and even make your resume look better.
And it is important to learn correct pronunciation as soon as possible for poor pronunciation can be hard to break. Native speakers of the language as well as others fluent in the language you are learning will appreciate your efforts to learn correct pronunciation.
Gather outside materials such as books, study guides, books on tape, and travel books to aid you in learning the language. Your textbooks can’t possibly teach you everything you need to know, so seeking outside sources is generally a good rule of thumb to keep in mind.
A significant motivator in learning a foreign language is traveling to the country where the language is spoken. That way, you can see firsthand how the language is used, learn the culture, and meet native speakers of the language. Native speakers appreciate sincere attempts of others who take the time to learn their language.
Seek out native speakers of your new language in your school or neighborhood. They can help you with many skills, including pronunciation, and they can provide immediate feedback on your progress.

| A．textbooks are not good for us when learning a foreign language |
| B．learning pronunciation well from the very beginning is very important |
| C．poor pronunciation can be easy to break with the help of native speakers |
| D．seeking too many outside sources will be more harmful than beneficial |

When the earth developed— which scientists believe may have happened about billions of years ago , many gases covered the earth . The gases caused the earth to be hot . But something wonderful happened . The temperature was just right for thick clouds to form . It rained very hard for a very long time . This gave the earth its oceans . Water made it possible for plants to grow . The plants created oxygen in the atmosphere . Oxygen is the gas that humans and animals breathe .
Only one other planet in the solar system seems to be something like the earth . That planet is Mars . Mars is smaller than the earth , and it is quite a bit cooler . But it is not too cold for humans . On some days , the temperatures are as cold as a winter day in the northern United States . If you wore a special spacesuit , you could walk around on Mars . You would have to bring your own air to breathe , though . The air on Mars is too thin to breathe . Mars has the largest volcano in the solar system . It is sixteen miles high . The highest volcano on the earth is five miles high . The most unexpected sight on Mars is dried-up river beds . Scientists believe that Mars was once much wetter that it is now . Does this mean there could have been living things on Mars ? Scientists are not sure , but there has been no sign so far .
