More and more people believe that technologies are great for learning. Today, teaching tools like iPads are used in a lot of courses, i    1     language, history and science.

The teachers 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 h    2     to the students who are learning a language at different paces.

There are other advantages for students. By using iPads, they can pay more attention to the material and learn more. Teaching notes are s    3     in their iPads and are easy to find. Some students spend more time studying now.

But many adults c    4     that technologies like iPads are doing harm to students. They worry that students might use iPads to download teaching notes and use them to cheat during exams. If a student spends more time watching videos on an iPad, he will have f    5     chances to have face-to-face communication with others.

However, technologies are a    6     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 c    7     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.

So, is it really true that life is better for teenagers now? It’s certainly true that many teenagers have got more things nowadays.     6     typical (典型的) family is smaller now, so parents have got more money to spend on each child. And many things are cheaper than they were when our parents were children.

    7     is probably the greatest change. For example, 40 years ago, no one could imagine a world with tiny computers and amazing smartphones. And now these things are used widely in our daily life.

    8    , technology often means we spend more time at home.

The study found that people who watched an average six hours of TV a day lived an average 4.8 years less than those     4     didn’t watch any television. Also, the participants lost 22 minutes of their life for each hour of TV they watched after age 25. Most people know that sitting in front of the television isn’t healthy. The more TV you watch, the     5     physically active you are. And the less exercise you get, the more chances you have of developing diseases such     6     diabetes and heart problems.

The study came out in the British Journal of Sports Medicine. Lennert Veerman is the main author of the study.     7     thinks that the habit of watching TV for a long time can lower life expectancy.

Transformers (变形金刚) can change from big robots into super-fast cars. Now, scientists at Harvard and Massachusetts Institute of Technology (MIT) have made these robots for real. They are not made of metal b    1     paper.

Some parts of these robots are made of toy-shop materials. They c    2     about 100 dollars. After being put in small b    3    , the paper robots will start to walk slowly. They transform from paper i    4     four-legged robots in just four minutes.

The robots are about 15 cm long, 15 cm wide and 5 cm tall. You can see that each of them is n    5     as big as a book. Each of the robots w    6     less than 85 grams. They move 5 cm per second. This s    7     type of robot can help people a lot. They can explore outer space and other dangerous places. They can also get into very small places to help save people.

Scientists think that these robots may s    8     a robotic revolution (革命) in the future. They believe that one day when someone wants a robot to walk his dog or play chess with him, he could go to a store with special equipment (设备) to m    9     it.

Of course, these robots are not Transformers from the movie. Once they have the battery and begin to assemble (组装) t    10    , they are fixed. This means that they can’t change back into paper or change into other shapes.
