Smoking in indoor public places including public working places, public transport vehicles and some other special outdoor working places has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.
First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled.
Next, banning smoking will put stress on smokers to give up. Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
Smoking in public places influences non-smokers to start smoking, especially . When teens see people around them smoking, they will follow them easily. Thus the number of teen smokers will increase. Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
Looking from the economic point of view, smoking should be banned to increase work productivity(生产率).Employees(雇员)who smoke usually take breaks to smoke while working. So the number of hours they put in their work is smaller.
If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse.
( ) 36. ________doesn’t belong to a non-smoking place.
A.A field B.A hospital C.A library D.A restaurant
( ) 37. The second paragraph mainly wants to tell us ______.
A. banning smoking is good for restaurants
B. banning smoking is good for non-smokers
C. banning smoking is good for spread of diseases
D. banning smoking is good for active smokers and passive smokers
( ) 38. How many advantages of banning smoking are mentioned in this passage?
A. Two. B. Four. C. Five. D. Six.
( ) 39.According to the text, the underlined word “adolescents” means ______.
A. men B. women C. adults D. teenagers{2017九年级历史寒假作业附加答案在线看}.
( ) 40. Which of the following statements in NOT true?
A. If smoking is banned, work productivity will increase.
B. If smoking is banned, the number of teen smokers will be larger.
C. If smoking is banned, it will make the environment become better.
D. If smoking is banned, smokers will learn how to live without smoking.

Look carefully at the back of a California state quarter．A man with a
walking stick is pictured there．A bird called a California condor(大秃鹫)is
flying overhead. Who is this man，and why is he so important that he is
featured(处于显著地位)on the back of a coin?

This means that people cannot build homes or businesses there. One of these parks is Yosemite National Park，the area that is featured on the back of the California quarter．
Though it has been almost one hundred years since John Muir died，people continue his work today．His work as a conservationist helped us to see the beauty of our natural world．John Muir made us understand the importance of protecting our earth and our resources---then，now，and for the future．
