【答案】

1】C

2】B

【解析】

1】全球气温升高后,我国西北干旱、半干旱地区因蒸发强烈,将会变得更加干旱;南北温差则不会变大,但1月0 ℃等温线将北移,水稻种植的北界也可能北移,会对社会经济发展产生影响,但是总体上是弊大于利。

2】煤炭和天然气均属于化石燃料,应该减少使用;为控制使用量,应该采用经济手段,提高能源污染税费;为了减少温室气体二氧化碳的排放量,各国政府应加强国际合作,提高能源利用效率,积极采用新能源。

【题目】概要写作

阅读下面短文,根据其内容写一篇60词左右的内容概要。

A woman gave up her fetus(胎儿) in Central China’s Hubei Province after her 13yearold daughter threatened to commit suicide.

The event drew people’s attention to the single child mentality,which may be an obstacle as the country tries to relax the singlechild policy.The woman,44,had been pregnant for 13 weeks.Her daughter became unhappy after knowing that she was going to have a brother or sister.Her anxiety reached its peak,when the ninthgrader cut her wrists with a razor blade in an attempted suicide,according to a report of the local Wuhan Evening News.

The case may sound extreme,but the girl is not the only child in China showing jealousy of a younger sibling.Zhuang Zhuang(not his real name) was 16 when his younger brother was born last year.Since then he’s fallen behind in his classes.

“They never cared about me again,” the teenager complained.“I’m under great pressure to do well in academic performances,so as to win attention from my parents.”

The onechild policy was relaxed in 2013,in an attempt to address the country’s declining labor force and aging population.A majority of the Chinese provincial regions,including the most populated Henan,have allowed couples to have a second child if either parent is an only child.Beijing also followed suit.Although 11 million couples have been granted a permit to have a second child,statistics from the National Health and Family Planning Commission show only close to one million couples out of them filed birth applications by the end of last year.“Economic cost”,“time cost” and “one child is enough” were listed as top reasons for not having a second child,according to a survey by China Youth Daily.Many parents give the third reason,out of concern for their first child.

Xia Xueluan,a sociology professor at Peking University,believes the onechild policy,enacted more than three decades ago,created many young “emperors” and “empresses” in China.“Parents spoiled their children,so many kids tend to be selfcentered without consideration for others,” he said.
