阅读下面短文,掌握其大意,然后从31-50各题所给的四个选项中选出最佳答案。
There was once a boy who suffered from a deadly disease and could die anytime. One day, he 31 a CD store and saw a young girl about his age and he knew it was love at first  32 . He opened the door and walked in. she looked up and asked, 33 I help you?”
He said, “Uh…Yeah…Umm…I would like to  34 a CD.”
He picked one out and gave her  35 for it.
“Would you like me to  36 it for you?” she asked, smiling her cute smile.
He nodded and she went to the back.
She came_37_with the wrapped CD and gave it to him. _38 , he went to that store every day and bought a CD. He was still too 39 to ask her out and he really wanted to. His mother found out about this and  40  him to just ask her.
So the next day, he took all his courage and went to the store. He bought a CD 41 he did every day and when she wasn’t looking, he  42  his phone number on the desk and ran out…
RING…The mother  43  the phone and said, “Hello?”
It was the girl! She asked for the boy and the mother started to cry and said, “He passed  44   yesterday…”
The mother went into the boy’s room. She was face to face with piles and piles of  45 CDs. She picked one up and started to open it.
46 , there was a CD and as took it out of the wrapper, out 47 a piece of paper. The mother picked it up and started to read it.
It 48 : Hi…I think U R really cute. Do U wanna go out with me? Love, Jacelyn.
The mother opened  49 CD…Again there was a piece of paper with the  50 words.

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。

下面是对“杂交”计算机的解说,有误的一项是( )。

A.它是将传统的电子转换器和光子结合而研制出来的。

B.它能更快地处理信息,并能克服高速运作时内部过热的问题。

C.光脑的许多更为关键的技术目前已获得了突破。

D.目前科学家们需要突破的是光开关的数量,这是“杂交”计算机最为关键的难题。
