Ⅵ.阅读理解
Accidents happen almost every day. Some accidents are not serious and some are. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents take place only on the roads or highways, or even at work places. Home accidents are just as common. Because very few home accidents are reported, people come to think that there are few accidents which happen in homes.
There have been many cases where people fall to their deaths from high rise flats. Children often fall over while coming down the stairs. Old people may slip (滑跤) on wet floors if they are not careful.
Nowadays there are a lot of modern electrical appliances (电器) such as rice cookers which make life easy for the modern house wives. These appliances can kill if they are not used in the proper way. Gas stoves (煤气灶) used for cooking are also dangerous if they are not properly used. They may cause burns or, in more serious cases, even fires.
But all such accidents can be stopped if we are careful and follow simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how to. It is safer to get them repaired by an electrician (电工).
1．Accidents take place ________.
A. mostly in homes
B. mostly on roads and highways
C. mostly in factories
D. almost everywhere
答案与解析 D 从第一段第四、五句可知，公路上、高速上，工作的地方和家里都可能发生事故。

D项正确。

2．Which of the following accidents may NOT happen in homes?
A. People may fall to death from high buildings.
B. People may be knocked down by cars on the roads.
C. Gas stoves may cause burns or even fires.
D. People may be killed by an electrical appliance.
答案与解析 B 根据常识就可以判断，B项不会发生在家里，从文章第二、三段叙述可知，A、C、D三项都可能发生在家里。

B项为正确选项。

3．People are advised ________.
A. to avoid using electrical appliances
B. to repair their own electrical appliances
C. not to repair their own electrical appliances
D. not to get their electrical appliances fixed
答案与解析 C 从文章最后一段可知，家里的电器最好由电工修理。

C项正确。
