We humans are only born with one set of eyes, so it's our job to take care of them for our whole lives. The good news is that if we do a few simple things every day, we can maintain (保持) our eyesight and reduce (減少) the risk of ever hurting our eyes.
Almost all doctors agree that we can improve and maintain good eyesight by eating lots of fresh fruits and vegetables. It is especially important for us to eat vegetables like carrots and sweet potatoes.  Besides, we need to protect our eyes when we spend a long time in bright sunlight. The best way to do. this is by wearing sunglasses that have 100% UV (紫外線)  protection. What's more, it is necessary to protect our eyes when we work with dangerous chemicals (化學物質).  For this reason we should always wear goggles in chemistry labs at work or at school. Finally, we should not spend too much time in front of the computer or television screen. That is why doctors advise if we have to use a computer for a long time, we should take a short break every fifteen or thirty minutes.
Maintaining good eyesight is important. If we do these few simple things we can protect our eyes and reduce the chances of losing our eyes. As the popular English expression goes, “It's all fun and game, until someone loses an eye.” When people say this, they mean that losing an eye is a very terrible thing

請認真閱讀下面短文，并根據短文內容回答問題。

    You would see a robot when you were reading a story or watching a movie, such as Star Wars. Today，however，science stories are becoming true. More and more robots are starting to be used in factories and our homes.

These robots are different in size，shape and colour，but all of them have the same type of man-made “brain”. The robots that work in factories are called industrial robots. These kinds of robots are cleverer and faster than the old ones. Industrial robots can do jobs that are often boring and sometimes dangerous.

Robots are already coming into American homes，though not as quickly as they are going into factories. We have made robots work at home. They can do some housework like cooking, or playing with people just for fun.

These robots aren’t as friendly and clever as those in Star Wars. But their makers say, today’s  home robots can “walk” and find objects in their way，though sometimes they may knock into(撞上) those objects. They can even carry objects, though sometimes they may drop those objects. Well, nobody is perfect. We may laugh at home robots today，but some day they will do better than humans. We humans can only see certain length of light, and hear certain sounds, while robots may see and hear better than we do.

In a word, robots will be widely used in our life in the future.

(請將答案寫在答題卡上)

1. Where are more and more robots starting to be used?

 

2. What do all kinds of robots have?

 

3. What kind of jobs can industrial robots do?

 

4. What do you think of today’s home robots?(請考生根據短文內容，自擬一句話作答)

 

5.What else do you want home robots to do for you? (請考生根據自己的想法，自擬一句話作答)
