问题 单项选择题 A1/A2型题

我国采用围生期,其概念可以界定为()。

A.自胚胎形成至产后1周

B.自孕满20周至产后1周

C.自孕满20周至产后4周

D.自孕满28周至产后1周

E.自孕满28周至产后4周

答案

参考答案:D

解析:国际上对围生期的规定有4种:①围生期Ⅰ:从妊娠满28周(即胎儿体重≥1000g或身长35cm)至产后1周;②围生期Ⅱ:从妊娠满20周(即胎儿体重≥500g或身长25cm)至产后4周;③围生期Ⅲ:从妊娠满28周至产后4周;④围生期Ⅳ:从胚胎形成至产后1周。根据世界卫生组织的推荐,我国采用围生期I计算围生期死亡率,故本题选D。避错:本题部分考生易选B,认为从首次产前检查开始就进入围生期,这是不对的,我国采用围生期从妊娠满28周(即胎儿体重≥1000g或身长35cm)至产后1周,因此,本题选D。

     Sadness is unpleasant, and in a society where personal happiness is prized above all else, there is

little tolerance for falling in despair.Especially now we've got drugs for getting rid of sad feelings-whether

it's after losing a job, the breakup of a relationship or the death of a loved one.So it's no surprise that

more and more people are taking them.

     But is this really such a good idea? A growing number of voices from the world of mental health

research are saying it isn't. They fear that the increasing tendency to treat normal sadness as a disease is

playing fast and loose (行为轻率). Sadness, they argue, serves a useful purpose-and if we lose it, we

lose out. Yet many psychiatrists (精神病医生) insist not.Sadness has a nasty habit of turning into

depression (抑郁症), they warn.Even when people are sad for good reason, they should take drugs to

make themselves feel better.

     So who is right? Is sadness something we cannot live without or something horrible never to touch?

     There are lots of ideas about why feeling sad should become part of human life. It may be a

selfprotection strategy, as other primates (灵长类) also show signs of sadness. A losing monkey that

doesn't show sadness after it loses a fight may be seen as continuing to challenge the winning monkey-and

that could result in death.

     In humans, sadness has a further function: we may display sadness as a form of communication. By

acting sad, we tell other community members that we need support.

     Then there is the idea that creativity is connected to dark moods. There are plenty of great artists,

writers and musicians who have suffered from depression or disorder. Scientists find that people with

signs of depression perform better at a creative task, and that negative moods make people think deeply

over the unhappy experience, which allows creative processes to come to the front. There is also

evidence that too much happiness can be bad for your career. A doctor found that people who scored

8 out of 10 on a happiness test were more successful in income and education than 9s or 10s. The

happiest people lose their willingness to make changes to their lives that may benefit them.
