請認真閱讀下面短文，并根據(jù)短文內(nèi)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)
小題1: Where are more and more robots starting to be used?
小題2: What do all kinds of robots have?
小題3: What kind of jobs can industrial robots do?
小題4: What do you think of today’s home robots?(請考生根據(jù)短文內(nèi)容，自擬一句話作答)
小題5:What else do you want home robots to do for you? (請考生根據(jù)自己的想法，自擬一句話作答)
