When other nine-year-old kids were playing games, she was working at a petrol station.When other teens were studying or going out, she struggled to find a place to sleep on the street.But she overcame these terrible setbacks to win a highly competitive scholarship and gain entry to Harvard University.And her amazing story has inspired a movie, “Homeless to Harvard: The Liz Murray Story”, shown in late April.

Liz Murray, a 22-year-old American girl, has been writing a real-life story of willpower and determination.Liz grew up in the shadow of two drug-addicted parents.There was never enough food or warm clothes in the house.Liz was the only member of the family who had a job.Her mother had AIDS and died when Liz was just 15 years old.The effect of that loss became a turning point in her life.Connecting the environment in which she had grown up with how her mother had died, she decided to do something about it.

Liz went back to school.She threw herself into her studies, never telling her teachers that she was homeless.At night, she lived on the streets.“What drove me to live on had something to do with understanding, by understanding that there was a whole other way of being.I had only experienced a small part of the society,” she wrote in her book Breaking Night.

She admitted that she used envy to drive herself on.She used the benefits that come easily to others, such as a safe living environment, to encourage herself that “next to nothing could hold me down”.She finished high school in just two years and won a full scholarship to study at Harvard University.But Liz decided to leave her top university for a couple of months earlier this year in order to take care of her father, who has also developed AIDS.“I love my parents so much.They are drug addicts.But I never forget that they love me all the time.”

Liz wants moviegoers (影迷) to come away with the idea that changing your life is “as simple as making a decision”.

1.In which order did the following things happen to Liz?

a.Her Mum died of AIDS.

b.She worked at a petrol station.

c.She got admitted into Harvard.

d.The movie about her life was put on.

e.She had trouble finding a place to sleep.

A.b, a, e, c, d      B.a, b, c, e, d      C.e, d, b, a, c      D.b, e, a, d, c

2.What decision did Liz make that changed her life?

A.To write Breaking Night.

B.To go to the best university.

C.To live through the difficult time.

D.To live a different life from her parents’.

3.When she wrote, “What drove me to live on … I had only experienced a small part of the

society”, she meant that ________.

A.she had little experience of social life

B.she could hardly understand the society

C.she would do something for her own life

D.she needed to travel more around the world

单项选择题

阅读下面短文,回答下 * * 道题。
光脑,人们也许还陌生,但制造光脑的尝试,科技界早在20世纪50年代就开始了,直到20世纪80年代中后期,才可以说有了决定意义的突破。20世纪90年代中期,世界上有一台光脑已由欧共体的英国、法国、比利时、德国、意大利等国的70多名科学家研制成功,其运算速度比电脑快1000倍。
科学家们预计,光脑的进一步研制将成为21世纪高科技课题。专家们预言,21世纪将是光脑时代。
光脑在哪些方面优越于电脑呢
光脑并行处理能力强,具有超高速运算速度。电子的传播速度为593千米/秒,而光子的速度为30万千米/秒。同时,超高速电脑只能在低温状态下工作,而光脑在室温下即可展开工作;和电脑相比,光脑信息存储量更大。
众所周知,对于电脑来说,电子是信息的载体,它只能通过一些相互绝缘的导线来传导,因此,尽管现今的电脑运算速度不断提高,但电脑的能力极限还是隐约可见的。就是在最佳情况下,电子在固体中的运行速度也远远不如光速。另外,无论微电路中的电流是多么的微弱,但随着装配密度的提高,散发的热量也在不断增加,使导体之间产生电磁作用,从而制约了电脑的运行速度。
和电脑相比,光脑的“无导线计算机”传递信息的平行通道,其密度实际上是无限的。一枚直径5分硬币大小的棱镜,它的通过能力超过全世界现有电话电缆的许多倍。
此外,还有极为理想的光辐射源——激光器可供使用。最主要的一点是光子不需要导线,即使在光线相交的情况下,它们之间也丝毫不会相互影响。
科学家正试验将传统的电子转换器和光子结合起来,制造一种“杂交”的计算机。这种计算机能更快地处理信息,而又可克服目前巨型机的一个大痼疾——内部过热。而一台光脑只需要一台电脑所需要能量的一小部分就能驱动,从而大大减少机器产生的热量。光脑的许多关键技术,如光存储技术、光互联技术、光电子集成电路等都己获得突破。目前,科研工作面临的迫切任务是最大幅度地增加光计算机的运算能力,即光开关的数量。
科学家预计,成熟的、可实际应用的光脑将会在21世纪初出现。

根据原文所给信息,以下分析错误的一项是( )。

A.脑在室温下信息存储量比电脑更大。

B.电脑的信息载体是只能通过一些相互绝缘的导线来传导的电子。

C.虽然电脑的运算速度还在不断提高,但其能力是有极限的。

D.电脑的运行速度和散热量是一对相互并存制约的矛盾。
