问题 单项选择题

下列选项中,属于主物与从物的是

A.房子与门窗

B.桌子与椅子

C.锁与钥匙

D.西服上衣与裤子

答案

参考答案:C

解析:[解题指导] 本题的考点为物的分类中的主物和从物。主物和从物是依据物是否可以独立存在及相互之间的关系进行的划分。主物和从物是分别独立的物,但主物是有独立效用的物,从物则从属于主物而使用,协助主物发挥效用。本题中,A项涉及的房子和门窗中,门窗属于房子的组成部分,而非独立的物,所以可以排除;B项涉及的椅子不一定从属于桌子而发挥作用,而且难有主次之分,所以也可排除。D项涉及的西服上衣和裤子均是分别有独立效用的物,无所谓哪个是协助另一个发挥效用,相互关系中也难有主次之分,故非主物和从物的关系,可以排除。故只有C为正确选项。[错误防范] 本题是概念理解题,需要明确主物和从物划分的标准以及认定主物和从物关系的方法。

     Pregnancy(妊娠) and childbirth kill more than 536,000 women a year. More than half of the cases

happened in Africa, according to the World Health Organization. In fact, most of the deaths are

preventable with basic medical care.

    The five leading causes are bleeding, infection, high blood pressure, longtime labor and bad

abortions (流产). Mothers' deaths from such causes were largely reduced nearly a century ago in

developed countries.

    Experts say that what kill many women are "the three delays",   the woman's delay in deciding to go

to the hospital, the time she loses traveling there and the hospital's delay in starting treatment. Only

about 15 percent of births have dangerous complications(并发症).

    Women lack education and information about birth control. Husbands and inlaws may decide where

a woman gives birth and insist that she stay at home to save money. However, there is no single solution

to a problem with so many factors shortages of doctors, nurses, drugs, equipment, roads and

transportation-though hospital officials are trying many things now.

    One stopgap measure to solve the problem for the present has been to train assistant medical officers,

to perform certain operations. Some African countries are now struggling to train more assistants and

midwives(接生婆), and provide places for pregnant women to stay near hospitals.

    But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital.

More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle

emergencies.
