plants and animals. However, the world's forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear？ If we cut down our forests, a lot of plants and animals will disappear from the world. In a lot of places the new farmland will soon look like the old deserts. Crops will not grow there. It will not rain very often, and the weather will get very hot. Perhaps the climate of the world will change. This will be dangerous for everyone in the world. That is why we must take care of our forests. (1)、The passage mainly tells us about the importance of taking care of plants. A：T B：F (2)、Forests are homes for different kinds of animals. A：T B：F (3)、The need for more wood and more land help to protect our forests. A：T B：F (4)、We'll have more and greater forestsn in 20 or 30 years in some people's view. A：T B：F (5)、The writer thinks it necessary to protect the forests. A：T B：F

How should we get（8）of such waste material in such a way（9）it will not harm the（10）？ Where can we（11）distribute it？ One idea is to put this radioactive waste inside a thick container, which is（12）dropped to the deep bottom of the ocean.（13）some scientists believe that this way of（14）nuclear waste could kill fish and other living things in the oceans or interfere（15）their growth. Another way to（16）nuclear waste is to send it into space, to the sun,（17）it would be burned. Other scientists suggest that this polluting material be（18）thousands of meters under the earth’s surface. Such underground areas must be free（19）possible earthquakes. Advances are being made. But it may still be many years（20）this problem could be finally settled. 1.

For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. &quot;While we teach, we learn,&quot; said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They&39;re documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction. Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who&39;re learning only for their own sake. But how can children, still learning themselves, teach others？ One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic. But the most cutting-edge tool under development is the &quot;teachable agent&quot;—a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty&39;s Brain, who has been &quot;taught&quot; about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking. Feedback from the teachable agents further enhances the tutors&39; learning. The agents&39; questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action. Above all, it&39;s the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else&39;s accomplishment. 1.
