New Technology Revolutionizes(变革) Learning
More and more people believe that technologies are great for learning. Today, such teaching tools as iPads are used in a lot of courses, including language, history and science.
Many teachers are supporters of using iPads in language learning. They say that students now have much more time for discussion in the classroom. Instead of spending valuable class time listening to texts or watching teaching videos, students can do this on their own and come to class prepared for discussion.
The teachers also say that iPads allow students to learn at their own pace. Some students might listen to a dialogue only once and understand it, so they can save time for doing other things. Other students, however, might need to listen to the same dialogue again and again to understand it. Using iPads is especially helpful to students who are learning a language at different paces.
The students who are using the new tool in some courses are also happy. They believe that using iPads is a more enjoyable way to learn (such as listening to stories and watching movies). The class has become much more interesting and creative.
There are other advantages for students. By using iPads, they can pay more attention to the material and learn more. Teaching notes are stored in their iPads and are easy to find .Some students spend more time studying now. “I can listen to my language material or watch teaching videos on the bus, instead of having to wait until I get home,” a student explained.
Many adults complain that technologies such as iPads are doing harm to students. They worry that students might use iPads to download teaching notes and use them to cheat during exams. Some believe that iPads may separate students from each other. If a student spends more time watching videos on an iPad, he will have fewer opportunities to have face-to-face communication with others.
However, technologies are already a part of most students’ day-to-day lives. As for cheating, teachers can ask students to hand in their iPads when they take exams. Education needs to make changes with the times as technology is playing an important part. We should look forward to a wonderful future when iPads and other technologies can add a lot to the classroom.
6. What does the expression “at their own pace” in Paragraph 3 probably mean?
A. According to their own timetable. B. Without their teachers’ help.
C. Because of their wonderful goals. D. Against their parents’ hope.
7. From the passage we can learn that____.
A. students with iPads have less discussion in class
B. students get more fun from learning with iPads
C. iPads help students save time waiting for buses
D. iPads prevent students from cheating in exams
8. The writer probably agrees that____.
A. teachers can take control of students’ learning
B. exam results depend a lot on now technology
C. technology in education has a bright future
D. note-taking is as helpful as video-watching

参考范文：
Many students like getting on-line very much. They can learn how to use the modern machine—computers. They can learn much more knowledge from the Internet. It can make them clever by playing different kinds of games.
But some students spend too much time playing games. Some even make friends on-line. It takes them too much time to write too many letters to each other, so they do worse in their lessons.
I think they mustn’t get on-line when they’re studying at school. They can do it in summer or winter holidays.

III. 阅读理解
A
Do you know why different animals or pests (害虫) have their special colors？Colors on them seem to be used mainly (主要地) to protect themselves.
Some birds like eating locusts (蝗虫), but birds cannot catch them easily. Why? Because locusts change their colors according to the colors of crops (庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others, so they have to hide (隐藏) themselves and appear (出现) only at night.
If you study animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have colors much like the trees.
A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger. While the liquid spreads out, its enemies (敌人) cannot find it, so it can escape (逃跑) at once. That is why it can live long, though it is not strong at all.

A. are small animals B. are easily found by birds

A. they have the colors much like the trees
B. they move quietly
C. they like brown and grey colors
D. they live in forests
4. Why can the kind of fish live long?
A. Because it is very big and strong.
B. Because it can send out a kind of very black liquid to help it escape from its enemies.
C. Because it can send out a kind of liquid to kill its enemies.
D. Because it swims faster than any other fish.

Zhalong is a nature reserve in Heilongjiang in northeast China. It is one of the world’s most important wetlands. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.
Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong Nature Reserve is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Some of them live in Zhalong.
Some people want to change the wetlands to make more space for farms and buildings. This means that there will be less and less space for wildlife.
More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.
Every year a lot of tourists go to Zhalong to watch birds. This year members of our Bird watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.
We do a bird count once a year. We are now inviting secondary school students to help. We need more people to help us count and do something to help the birds. Many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife.

III. 阅读理解。
