【題目】（題文）Bad breath (呼吸) is a big problem. You can make people around you feel bad when you’re talking to them.

Why do some people have bad breath? If you don’t brush your teeth, bacteria (細菌) will live in your mouth and between your teeth and make your breath smell (聞起來) bad. Foods like onions can also make bad breath. Smoking (吸煙) is an important reason for bad breath, too.

How can we stop bad breath? Some people say that mouthwash (漱口水) can make bad breath go away, but it isn’t true. Mouthwash only stops bad breath for a short time. Some people also say that brushing your teeth can stop bad breath. The fact (事實) is that most people only brush their teeth for 30 to 45 seconds and it doesn’t work. To clean all of your teeth, you should brush for about 2 minutes twice a day.

If you don’t want to have bad breath, make sure you’re looking after your teeth and mouth well.

【題目】閱讀下面材料，然后從各題所給的四個選項中選出一個最佳選項。
D
The government in China plans to end its one-child policy(政策) and let families have two children instead.
The plan was given on Thursday after political meetings in Beijing. There are a number of reasons for the change in policy. The change is meant to balance population development, stop a falling birth rate and strengthen the country's labor(勞動力) force.
China, with the largest population in the world, started the one-child policy in 1980. But the government allowed only a small number of couples to have two children. For example, some families in the countryside could have two children, if the first-born child is a girl.
In 2013, the Chinese government gave other couples a chance to have two children if one of them was an only child.
Jiang Quanbao, a teacher and population expert, explained how Chinese families react（反應） to the newest policy. "Too many young people in the cities are no longer interested in having a second child," he said. "People in the countryside are more interested. But some of them are already allowed to have two children."
At the end of 2014, China had 1. 37 billion people. A total of 800 million of them have jobs. But the labor market population will drop in 35 years. That is to say, the country will be in great need of labor by the year 2050. With the two-child policy, an increase in births can solve this problem.
Boys and girls, what do you think of the two-child policy? Do you want to have a new-born brother or a sister?
（1）Why does the government plan to end the one-child policy?
A.Because we need a larger population.
B.Because millions of people have jobs.
C.Because most families want to have a second child.
D.Because we need to strengthen the country's labor force.
（2）How do most young people in the cities react to the two-child policy?
A.They support the policy.
B.They don't think it is good.
C.They're very interested.
D.They're not interested any more.
（3）When will our country be in great need of labor if the one-child policy continues?
A.In 2015.
B.In 2035.
C.In 2050.
D.In 2070.
（4）The Two-Children Policy mainly ______.
A.helps solve the problems of aging population and labor shortages.
B.doesn't allow one couple to have two children.
C.has a bad influence on one's mental health.
D.encourages one couple to have more than two children.
