     The United States is already one year into a depression That was the news this week from the

Na-tional Bureau of Economic Research. The downturn is the longest since a depression that began in

1981and lasted sixteen months.

     Economists generally wait for production to shrink for six months in a row before they declare a

re-cession. But the bureau, a private group, uses a wider set of information to measure the economy.

Thenews only confirmed what many people already knew: that the world's largest economy is weak and

maynot recover soon.

     Worsening conclitions have led to a big drop in spending, especially on costly products like new cars.

Even Japanese automaker Toyota saw its sales fall thirty - four percent in the United States in November

from a year ago.

     The heads of Chrysler, Ford and General Motors retumed to Congress this week to again ask for

federal aid.  Congressional leaders denounced (指责) them two weeks ago after they came in private

jets with no clear plans for saving their industry. This time, the chiefs drove to Washington in fuel- saving

hybrid vehicles. And their companies presented detailed restructuring plans. The reguest for aid has risen

from twenty-five billion dollars two weeks ago to thirty-four billion in loans and credit lines.

     G.M. wants almost half of that, and says it needs four billion dollars this month. It warned that without

support it cannot continue to operate.

     Ford is in a better position, But the sharing of suppliers means it could be affected if G.M. or

     Chrysler fails. Ford is asking for a nine billion dollar credit line in case it needs it.

     Chrysler is the smallest and most trouble of America's Big Three. It says it needs a seven billion dollar

loan by the end of the month.

     Two days of congressional hearings began Thursday in the Senate Banking Committee. The chairman, Democrat Chris Dodd, said he would support helping the automakers for the good of the economy.

     But the committee's top Republican, Richard Shelby, continued to express opposition to a bailout

(贿政援助).

     A main root of the world financial crisis is the weak housing market in the United States. The

Trea-sury Department has been under pressure to help troubled homeowners. Now comes news that the

depart-ment is developing a plan aimed at reducing interest rates on mortgage loans (汽车贷款) for

some buyers of homes. That could be good for homeowners trying to sell.

1. From the first two paragraphs, we know        .

A. the United States is expected to recover soon

B. the depression has lasted more than 16 months

C. the depression is much more severe than expected

D. the depression will last no more than 6 months

2. Why were the automakers refused for federal aid two weeks ago?

A. Because the government had no extra money to help.

B. Because they didn't have a ciear plan to save their industry.

C. Because they had wasted too much on costly new cars.

D. Because they had enough money to save their industry.

3. Which of the following is asking for the largest federal aide

A. G.M.            

B. Toyota.            

C. Chrysler.            

D. Ford.

4. From the passage we may know Richard Shelby         tile automakers' request for federal aid?

A. was for      

B. was against      

C. didn't care about    

D. took no notice of

5. Which of the following statement is NOT true according to the passage?

A. The hearings on Thursday agreed on a federal aid to the automakers.

B. The main cause of the crisis is weak housing market in the U.S..

C. The government is taking measures to save t he housing market.

D. The Treasury Department had to help the troubled homeowners.

金属历来都是通过采矿、冶金制取的,可是80年代初期,科学家发现在聚乙炔中加入强氧化剂或还原剂后,它的导电性能大大提高。因为这种塑料具有金属的一般特性,所以人们称它为“人造金属”。近年来,它的发展极为神速,人们又先后研制成功了聚苯乙炔、聚苯硫醚和聚双炔类等。这种人造金属不仅具有金属光泽,还能导电传热,其用途十分引人瞩目。
“人造金属”最奇特的功能是它的导电性。与普通塑料不同的是,“人造金属”塑料具有一种独特的线型结构,许多同样的分子能奇妙地结合起来,并带有较多的“自由”电子。这就使原来的塑料改变了物理性能,能够导电。它的导电率比铜、银还要高。普通金属的导电性,随着温度的降低而增大,在接近绝对零度时成为超导,但这种低温度很难得到。而人造金属却相反。随着温度升高,外围“自由”电子释放越来越多,因此导电性增大,在常温下呈现出超导电性能。实现超导,由低温变成常温,这是人造金属创造的一大奇迹,是科学家梦寐以求的目标,用超导体制造的发电机,它的效率可以从30%提高到98%,超导电线将使远距离无损耗输电的设想成为可能,使火车悬浮在轨道上高速运行,将使控热核聚变反应成为现实,最终解决能源问题。
人造金属的另一突出贡献是,用它制成的新型电池代替笨重、硕大的铅蓄电池,可以使人们长期用蓄电池做动力汽车有了(①)的可能。人造金属电池可提供相当常规电池10倍的电力,不需要维修,充电次数可达1000次以上,使用寿命比铅蓄电池长4~5倍,而且不会污染环境。
人造金属在外压和光的作用下,能产生电场效应,把它装在扩音器上,能将声音放大;把它放在红外摄像机上,在红外热能作用下,也能产生工作电流进行录像。此外,人造金属弹性大、易加工、重量轻、耐磨蚀性能好、强度高、成本低。

准确揭示作者引述贵妇人与法拉第对话的用意的一项是( )。

A.形象地反映了法拉第的价值观:科学发现的价值远远高于应用价值

B.主张人们关注科学发现的应用,但科学家不能助长世俗者急功近利

C.说明从科学发现到应用有一个过程,其应用价值是难以确切预测的

D.表明法拉第无意戏谑贵妇人,而是以科学态度审视自己的重大发现
