问题 读图填空题

2011年5月15日黄河口国际马拉松赛暨全国马拉松积分赛在东营市举行。马拉松长跑是赛程超过40km历时2h以上的极限运动。右图示运动员以淀粉为主要食物的消化终产物a进入血液和组织细胞的过程及部分相关的代谢活动示意图。请据图分析:

(1)淀粉消化的终产物a是                

(2)小肠吸收来的a被运至下肢骨骼肌利用,整个过程中血液经过心脏        次。

(3)组织细胞产生的c通过             作用进入血液。

(4)组织细胞利用血液循环获得a和b,通过呼吸作用释放出能量用于         

                              

(5)d与血液相比较,在成分上的区别是                ;e进入血液的生理过程称为                     

(6)呼出气体c和排出尿液f的过程称都可称为              

答案

(1)葡萄糖  (2)2 (3)扩散  (4)人体的各项生理活动和维持体温(或人体的各项生理活动) (5)d不含有血细胞和大分子蛋白质  重吸收作用  (6)排泄

淀粉最终消化的产物是葡萄糖,葡萄糖被吸收进入血液后,会通过上下腔静脉回到心脏的右心房,再到右心室,进行肺循环后,又回到心脏的左心房,所以整个过程经过心脏2次,组织细胞与血液进行气体交换是通过扩散作用实现的,呼吸作用的实质是分解有机物,释放能量供生命活动的利用,因为肾小球具有滤过作用,所以原尿d中不含有大分子蛋白质和血细胞,肾小管具有重吸收作用,能将全部的葡萄糖、大部分的水和部分无机盐重吸收。人体排出废物的过程叫做排泄。

The past few years have been busy ones for human-rights organisations. In prosecuting the so-called war on terror, many governments in Western countries where freedoms seemed secure have been tempted to nibble away at them, while doughty campaigners such as Amnesty International (国际特殊组织) also exist for defence. Yet Amnesty no longer makes the splash it used to in the rich world. The organisation is as vocal as it ever was. But some years ago it decided to dilute a traditional focus on political rights by mixing in a new category called social and economic rights.

You might suppose that the more of rights you campaign for the better. Why not add pressing social and economic concerns to stuffy old political rights such as free speech and free elections What use is a vote if you are starving Are not access to jobs, housing, health care and food basic rights too No: few rights are truly universal, and letting them multiply weakens them.

Food, jobs and housing are certainly necessities, but there’s no use to call them "rights". When a government looks someone up without a fair trial, the victim, perpetrator and remedy are pretty clear. This clarity seldom applies to social and economic "rights". Who should be educated in which subjects for how long at what cost in taxpayers’ money is a political question best settled at the ballot box (投票箱). And no economic system known to man guarantees a proper job for everyone all the time.

It is hardly an accident that the countries keenest to use the language of social and economic rights tend to be those that show least respect for rights of the traditional sort. And it could not be further from the truth. For people in the poor world, as for people everywhere, the most reliable method yet invented to ensure that governments provide people with social and economic necessities are called politics. That is why the rights that make open polities possible — free speech, due process, protection from arbitrary punishment— are so precious. Insisting on their enforcement is worth more than any number of grandiloquent but unenforceable declarations demanding jobs, education and housing for all.

Many do-gooding outfits suffer from having too broad a focus and too narrow a base. Amnesty used to appeal to people of all political persuasions and none, and concentrate on a hard core of well-defined basic liberties. However, by trying in recent years to borrow moral authority from the campaigns and leaders of the past and lend it to the cause of social reform, Amnesty has succeeded only in muffling what was once its central message, at the very moment when governments in the West need to hear it again.

According to Paragraph land 2, which of the following items is social and economic right()

A. Whether a group can express its opinion freely

B. Whether the president of a country is elected by the people

C. Whether every citizen of a country can get a job

D. Whether the law process is fair and transparent
