My children and I were finishing the last minute preparations for Kathy’s birthday celebration. At one store we had bought a   21   balloon with Kathy’s favorite character design on it. We had to make one more stop at another store to complete our   22  . I sent my older daughter and her little brother out to our   23   while my other daughter and I were   24   at the cashier line.

A very short time later, my older daughter with little brother came running back into the store; upset that Kathy’s birthday balloon had   25   while they trying to get into the car. I was tired from   26  , but I sent them back to the vehicle   27   them not to worry because we would get Kathy another   28  . I paid for our purchases all the while trying to think of the most expedient place to   29   another balloon.

As Kathy and I   30   our car a lady with   31   face came up to us. She   32   some folded bills in my hand. She   33   to me that she had seen what had happened and did not   34   my older daughter or my younger daughter to be   35   at the loss of the balloon.

I thanked her for kindness and   36   to give her the money back; as it was not a   37   to get another balloon. But she said, “I   38   children and I like to see them be happy.” I was overwhelmed by the   39   of a total stranger that my daughters and I hugged the lady   40    her for kindness. She left so quickly that I was unable to even ask her name. Finally, I looked in my hand what I found was not just a single one dollar bill but four one dollar bills.

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.

“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

【文章大意】本篇为科普短文，介绍由美国密苏里大学研究者所开发的核能电池的情况。

71. Which of the following is true of Jae Kwon?

A. He teaches chemistry at MU.     B. He developed a chemical battery.

C. He is working on a nuclear energy source.

D. He made a breakthrough in computer engineering.

72. Jae Kwon gave examples in Paragraph 4_________.

A. to show chemical batteries are widely applied.  

B. to introduce nuclear batteries can be safely used.

C. to describe a nuclear-powered system.       

 D. to introduce various energy sources.

73. Liquid semiconductor is used to _________.

A. get rid of the radioactive waste       

B. test the power of nuclear batteries.

C. decrease the size of nuclear batteries  

D. reduce the damage to lattice structure.

74. According to Jae Kwon, his nuclear battery _______.

A. uses a solid semiconductor        B. will soon replace the present ones.

C. could be extremely thin           D. has passed the final test.

75. The text is most probably a ________.

A. science news report        B. book review   

C. newspaper ad          D. science fiction story

【答案解析】

71. 【解析】选C。细节理解题。根据第一段的University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient及第三段的叙述可知，Kwon在研究一种核能电池，所以C项正确。

72. 【解析】选B。细节理解题。根据文章第四段可知Kwon举例的目的是为了说明核能电池是安全性。

73. 【解析】选D。 细节理解题。根据part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,”及“By using a liquid semiconductor, we believe we can minimize that problem.”可知，通过使用液态半导体材料，可减少对晶体结构的破坏。

74. 【解析】选C。 细节理解题。根据Kwon said that battery could be thinner than the thickness of human hair可知C项正确。

75. 【解析】选A。推理判断题。本文讲述了Kwon的原子能电池的有关情况，文章体裁应属于科普文章，所以A项正确。

高考预练

Ⅰ.单项填空

1．(2012·济南5月份练习)I have been working with Lily for years，and never before __________ her so serious!

A．I found　　　　　　　　　 B．I have found

C．did I find   D．have I found

解析：选D。考查倒装句。否定副词never放于句首时，句子要用部分倒装，所以排除A、B两项。根据语境可知，这之前“我”从没有发现她这么严肃。故选D。

2．(2012·淄博模拟)________ the key to the car when my boss came towards me.Finally I could drive him home as usual.

A．Never had I found   B．Seldom did I find

C．Hardly had I found   D．No sooner did I find

解析：选C。考查倒装句。由语境知，“我”刚找到车钥匙，老板就朝“我”走来了。hardly...when...是固定句型，意为“刚……就……”。

3．(2012·临沂质量检测)Only when __________ to explain __________ the reason for this.

A．did he start；she realized

B．he started；did she realize

C．did he start；she had realized

D．he started；had she realized

解析：选B。考查倒装句。句意：只有当他解释时，她才意识到原因所在。若only后跟了副词、介词短语或从句等状语且置于句首时，则主句用倒装结构。故此处when引导从句不需要倒装，后面的主句需要倒装。即B项正确。

4．(2012·青岛第二次统一检测)The Japanese __________ suffering from the worst natural disasters __________.

A．are；ever since   B．are；of all time

C．is；ever since   D．is；of all time

解析：选B。考查主谓一致和介词短语辨析。句意：日本人遭受着有史以来最严重的自然灾害。主语the Japanese，表示复数概念，所以谓语动词用are；ever since“从那时起一直到现在”，通常与完成时连用，故排除。of all time意为“有史以来”，符合题意。故选B项。

5．(2012·太原模拟)More than a dozen students in that school ________abroad for further study every year.

A．sent   B．are sent

C．have been sent   D．have sent

解析：选B。句意：每年那所学校有十多个学生被送到国外深造。more than a dozen十多个，谓语动词用复数；另外，句子的时间状语为every year，所以用一般现在时。

6．(2012·南昌一模)When I try to understand________ that prevents so many Americans from being as happy as one might expect，it seems to me that there are two causes.

A．why it does   B．what it does

C．what it is   D．why it is

解析：选C。根据宾语从句中的that和选项可以判断这是一个强调句型，宾语从句中缺少主语，所以只能用what来引导。

7．(2012·江西九校联考)________she is not so cheerful________she used to be?

A．How it is that；as   B．How is it that；as

C．Is it why；that   D．What is it that；what

解析：选B。句意：她怎么不像过去那样高兴了呢？强调句的特殊疑问句式：特殊疑问词＋is/was it that＋原句剩余部分？D项中的what不正确。

8．(2012·济南一中阶段测试)Hearing the bell ringing，out________.

A．rushing the children   B．were rushing the children

C．rushed the children   D．the children rushed

解析：选C。句意：听到铃声，孩子们冲了出来。表示方位的副词位于句首，且主语为名词时，该句要全部倒装，即：副词＋谓语动词＋主语。

9．(2012·湖南师大附中)—Mum，I am afraid I won’t do well in the coming test.

—Honey，________more careful，________you will make it.

A．is；so   B．be；and

C．be；then   D．being；and

解析：选B。句意：——妈妈，我恐怕考不好了。——宝贝，仔细些，你会考好的。考查“祈使句＋and＋简单句”这一结构，该句相当于“含if引导的条件状语从句的复合句”，即：If you are more careful，you will  make it.。
