【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。

If you know something is bad for you，why can’t you just stop？About 70% of smokers say they would like to stop.Drug and alcohol abusers struggle to give up the bad habits that hurt their bodies and destroy families and friendships.And many of us have unhealthy weight that we could lose if only we would eat right and exercise more.So why don’t we do it?

Some scientists have been searching for answers.They’ve studied what happens in our brains as habits form.They’ve found answers to why bad habits，once formed，are so difficult to kick.And they’re developing ways to help us make the changes we’d like to make.

Habits are a normal part of life，and are often helpful.“We wake up every morning，shower，comb our hair or brush our teeth without being aware of it，” Volkow says.We can drive along familiar routes without really thinking about the directions.“When behaviors become automatic，it gives us an advantage，because the brain does not have to perform the action on purpose，” Volkow says.This frees up our brains to focus on different things.

One way to kick bad habits is to focus on your unhealthy habits.Then try your best to stop them.For example，habits can be linked in our minds to certain places and activities.You could develop a plan，to avoid walking down the hall where there’s a candy machine.Try to avoid going to places where you’ve usually smoked.Stay away from friends and situations linked to problem drinking or drug use.

Another helpful way is to replace unhealthy habits with new，healthy ones.“It doesn’t work for everyone，” Volkow says.“But certain groups of patients who have a history of taking drugs can do something else like running and it helps them stay away from drugs.”

【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.
