Do you plan to go to Hong Kong Disneyland with your family this summer? If your dad smokes, you may have to ask him to be careful. From January 1st, Hong Kong banned(禁止)smoking in most public places.  

These places include restaurants, workplaces, schools and so on. Even smoking in some outdoor places is not allowed, for example, beaches, sports ground, museums and most areas of public parks.  

 Hong Kong  hopes the ban can stop passive smoking. What is passive smoking? When people smoke in a restaurant or on a bus, others have to smoke too. They don’t want to smoke but they have no choice. This is passive smoking. It is bad for people’s health.  

And it’ll be better if more people in  Hong Kong  give up smoking because of the ban. Jack Lee, a 26-year-old student says, “The ban is really good. I don’t like people smoking next to me. It’s so smoky and smelly.”  

If someone breaks the ban, he will be fined HK$5,000.  

 Hong Kong  is not the first Asian city to have a smoking ban. On January 1, 2006,   Singapore   banned smoking in most public places.  

1.Smoking is not allowed             in  Hong Kong .  

A. in indoor places     B. in most public places       C. at home   

2.Which outdoor place is not mentioned in the passage?  

A. The park        B. The beach             C. The airport  

3. What’s the purpose of the smoking ban in  Hong Kong ?  

A. To stop passive smoking.  

B. To stop the sale of cigarettes.  

C. To stop people from smoking.  

4.The example in Paragraph 4 shows (证明)that           .  

A. Jack Lee likes smoking very much    B. people in  Hong Kong  support the ban  

C. Jack Lee is used to smoking   

5.What’s the Chinese meaning of the underlined word “fined”?
