     Once in a village, the villagers built a new church building and people came from far and wide to see it.

They admired its beauty! They said it was the most beautiful building in the world. Up on the roof, a little nail

heard the people praising everything about the lovely structure - except the nail! No one even knew he was

there, and he became very angry and sad.

     "If I am not important, nobody will miss me if I quit!" So the nail then released (松开) its hold, got down

from the roof, and fell into the mud.

      That night it rained and rained. Soon, the board that had no nail was blown away, and the roof began to

leak  (漏水). The water flowed down along the walls and over the beautiful pictures on the walls. The plaster (石膏) began to fall, the floor was ruined, and the Bible was also ruined by water. All this was because a little

 nail decided to quit!

     But what of the nail? While holding the board, it was not known by others but it was useful. Buried in the

mud now, it was useless and would soon be eaten up by rust!

     What the story wants to say is that every member is important to a whole group!

     You may, like the nail, feel not important at times, but just like the nail, your absence is felt. A big building

might fall to pieces. You are important to a group even if you are small.

1. Why did the nail decide to quit?

A. Because he was not able to hold on any longer.

B. Because he was angry and sad without people's praising him.

C. Because he knew a big nail would replace him.

2. What's the result of the nail's giving up?

 A. People began to realize the importance of the nail.

B. The nail was put in a more important position.

C. Many things in the building were ruined and the nail was eaten up by rust.

D. The nail regretted his original decision at last.

3. We can conclude that the nail was ______ in the passage.

A. clever

下列是有关收入分配差距的材料:
材料1
长沙市企业调查队的一次抽样调查表明,这些年来,该市各行业之间的职工工资收入分配差距拉大,特别是一些垄断性行业的职工收入明显偏高,而且差距。还有进一步扩大的趋势。在调查的16个行业中,航空业、烟草制造业、文教、出版业、电力生产业、电信业等一些国家垄断性行业年均工资水平居前位,而煤矿开采业、制造业等一些盈利能力较弱、竞争激烈的行业年均工资水平则处于末位。
1999年,长沙行业工资最高与最低差距为25174.7元,2000年,差距为30711.7元,高低差距比例由6.55:1扩大到6.81:1。
从人均年工资的增幅看,工资高的行业基数大,增长幅度亦大,而工资低的行业基数小,增长幅度亦小,个别行业甚至出现下降的现象。一些垄断性行业的工资增幅达到了20.2%至31%,而日用电器制造业、煤矿开采业工资却呈降势。
——摘自YKCYDT089——长沙行业收入分配差距拉大
材料2
我国收入差距拉大过程,如果从1985年算起,已经持续20年了,差距继续拉大的趋势已经非常明显。到目前为止,差距拉得过大已是不争的事实。从居民收入情况看,基尼系数已从1995年的0.389上升到2002年的0.435,超过了国际公认的0.4的警戒线、城乡差距从1985~2003年的 18年间快速扩大,农民人均纯收入年均增长4.3%,而城市人均可支配收入年均增长8.7%。2004年城乡居民收入差距是3.2:1,加上各种福利差距,实际达到6:1。尽管去年中央采取了多项重大措施,使农民人均收入增加了300元,但城市人均收入增加900元,城乡差距仍在继续扩大。从地区差距看,2003年东部地区人均GDP分别相当于中部和西部地区的1.91倍和2.38倍。公务员的工资在不同地区、不同行业、不同单位差别也太大。

材料3
“居民收入分配预警系统”显示,2003年城镇居民内部总体收入差距不断扩大,其评价指数为 69分,低于70分的“黄灯”警戒线。城镇居民最高组与最低组之间的收入之比从2002年的5.2:1扩大到2003年的5.4:1。城乡居民收入分配差距拉大。城乡收入差距评分从1980年的80分左右下降到2003年的72.7,接近“黄灯”警戒线。1980年城镇人均可支配收入是农村人均纯收入的 2.5倍,到2003年该比例扩大到3.23。农村居民收入差距拉大,贫富悬殊的评价指数为64分,已接近60分的“红灯”警戒线。1992年贫困农民的收入上限与一般农民之比为1:2.45,2004年扩大到1:4.39。研究组专家据此提出,当前中国居民收入分配差距中最核心的问题是农民收入过低问题,更明确地说是农民中低收入者的收入问题。
