2004年,河北省甲市乙区人民法院在对一起侵权纠纷案件的判决依法强制执行的过程中,发现被告应当归还的部分财物还存放在其居住在河南省丙县的表兄家中。于是,甲市乙区人民法院委托丙县人民法院代为执行。丙县人民法院在收到乙区人民法院的委托函件后对委托执行的生效判决进行了仔细的审查,认为该判决证据不足,拒绝对其进行执行。甲市乙区人民法院无奈,请求其上级人民法院甲市中级人民法院指令丙县人民法院执行,被甲市中级人民法院拒绝。关于本案以下说法正确的是:

C.丙县人民法院应当接受委托法院的请求进行执行,不得拒绝执行

    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.

1. Which is not included in the five leading causes of women's deaths during pregnancy and childbirth? 

A. Infection.

B. High blood pressure.

C. Traveling long distances.

D. Bleeding.

2. The underlined word "stopgap" probably means "________" in     the passage.

A. final      

B. temporary

C. effective    

D. instant

3. What can we learn from this passage? 

A. Most problems that cause women's deaths during pregnancy and childbirth can be treated or

prevented.

B. Developed countries should help African countries reduce mothers' deaths.

C. The husbands in poor countries should take responsibility for their wives' deaths.

D. The governments of African countries have to take more effective measures to save pregnant women.

4. What is the author's attitude towards the future of preventing women's deaths during pregnancy and

childbirth?

A. Positive.                

B. Negative.

C. Objective.                

D. Subjective.

我的理想

俗话说:“人无志而不立。”一个人假若没有远大的理想,是不可能有所作为的。从远古时代的盘古开天辟地到如今的知识爆炸、信息革命,多少年,多少代,多少仁人志士都有着崇高的理想。理想是我们奋斗前进、勇于创新的动力;理想是人生的指路灯;理想是战胜困难的力量源泉……懵懂的小时候,当我看到那些富有爱心的幼儿教师用手轻轻抚摸摔伤了的小朋友红扑扑的小脸蛋,想方设法来哄他们的时候,我便在童稚的心里立下志愿——我,也要做一名杰出的幼儿教师,做一位辛勤的园丁,细心照料祖国大花园里的每一朵鲜花!如果我的理想实现了,成为了现实的话,我就会把上面的语句落实到行动当中去。我会用爱心去征服那一个个顽皮的身影,让他们也懂得,老师是爱他们的。当然,在必要的时候,我也会给予他们一些小小的惩罚,让可爱的小朋友们认识到错误、牢记在心,下定决心改正!最重要的是,我要让他们脱离幼儿时代就背负起学习重担的阴影,我会用他们喜欢的方式让小朋友们爱上学习,从而为成为祖国的栋梁而奋斗!但我不会逼迫他们去学习!然而现在,这一切都还只是泡影。理想是一个深渊,从跳下的那一刻起,就逼迫你奋力搏击。要么,大鹏展翅,扶摇而上;要么,石沉渊底,再无声响……而我,则选择前者,我会努力奋斗,向自己的理想一步步迈进!

想一想:同学们一定也有自己的理想吧,或许你想成为一名科学家,或许你想当一名医生,再或许你想当一名演员。我们即将面临升学或者就业的选择,一旦你的理想不能实现,你是更改理想目标,还是向现实妥协呢?你同意文中作者对理想描述的观点吗?你认为理想像什么?
