  A few years ago I had an “aha!” moment regarding handwriting.
  I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task. It occurred at first that I did not recognize the handwriting,and then I realized whose it must be. I finally became aware of the fact that I had been working with this colleague for at least a year,maybe two,and yet I did not recognize her handwriting at that point.
  It was a very important event in the computerization of life—a sign that the informal. Friendly communication of people working together in an office had changed from notes in pen to instant messages and emails. There was a time when our workdays were filled with little letters,and we recognized one another's handwriting the way we knew voices or faces.
  As a child visiting my father’s office,1 was pleased to recognize,in little notes on the desks of his staff,the same handwriting 1 would see at home in the notes he would leave on the fridge—except that those notes were signed “dad” instead of “RFW”.
  All this has been on my mind because of the talk about The Rise and Fall of Handwriting,a book by Florey. Sire shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well,but many others argue that people in a digital age can’t be expected to learn to hold a pen.
  I don’t buy it.
  I don’t want to see anyone cut off from the expressive,personal associations that a pen still promotes better than a digital keyboard does. For many a biographer,part of really getting to know their subjects is learning to read their handwriting.
  What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16th-century Italy. That may sound impossibly grand—as if they want kids to learn to draw by copying classical paintings. However,they have worked in many school systems.
  51. Why was the author surprised at not recognizing his colleague’s handwriting?
  A. He had worked with his colleague long enough.
  B. His colleague’s handwriting was SO beautiful.
  C. His colleague’s handwriting was SO terrible.
  D. He still had a 1ot of Work to do.
  52. People working together in an office used to ____________.
  A. talk more about handwriting
  B. take more notes on workdays
  C. know better one another's handwriting
  D. communicate better with one another
  53. The author’s father wrote notes in pen _________.
  A. to both his family and his staff
  B. to his family in small letters
  C. to his family on the fridge
  D. to his staff on the desk
  54. According to the author,handwritten notes _______.
  A. are harder to teach in schools
  B. attract more attention
  C. are used only between friends
  D. carry more message
  55. We can learn from the passage that the author __________.
  A. thinks it impossible to teach handwriting
  B. does not want to lose handwriting
  C. puts the blame on the computer
  D. does not agree with Florey
  本文是一篇夹叙夹议的文章,通过一时辨认不出一位老同事的字迹及其回顾,对在电脑冲击下,书法受忽视感到惋惜,并认为中小学应当加强书法教学。

  “Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
  The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
  Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version of the software, users can also send a spoken message.
  The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
  In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
  The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
  If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
  Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
  Other security software allows users to erase data remotely or lock down the computer.
  72. The expression “to give the thief a piece of their mind “can be understood as “_______”
  A. to give the thief an alert mind
  B. to express the owners’ anger to the thief
  C. to remind the thief of this conscience
  D. to make the thief give up his mind
 【答案】B。
 【解析】句意理解题。抓住短语中的their(their指的是电脑被偷的人),在结合文中前面的描述我们可以断定该短语的意思是to express the owners’ anger to the thief
  73. Different from other security software, Retriever can .
  A. record the stealing process B. help recognize the lost laptop
  C. lock down the computer remotely D. send a spoken message
 【答案】D
 【解析】细节理解题。第三段最后一句:Under the latest version of the software, users can also send a spoken message.
  74. One fun_ction of the program is that it allows the owner to _____ at a distance.
  A. change some access details for switching on the laptop
  B. turn on the laptop by using the original password
  C. operate the laptop by means of and alternative password
  D. erase the information kept in the stolen laptop
 【答案】A。
 【解析】细节推理判断题。由下句话:Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.该句话告诉我们失主可以远程改变一些登陆电脑的信息,如密码等。
  75. Which of the following can best summarize the main idea of the passage?
  A. With no Retriever, thousands of laptops are stolen every year.
  B. A new soft ware provides a means to reduce laptop theft.
  C. Retriever has helped to find thieves and lost computers.
  D. A new program offers a communication platform with the thief.
 【答案】B
 【解析】主旨大意题。文章主要给读者介绍了一种新型的程序,改程序可以降低电脑的失窃率。同时还介绍了该程序的工作原理。

With the development of the Internet(随着因特网的发展) and the popularization of computers, shopping on the Internet has become a commonplace in our life. Here consumers can buy almost everything they need.
Shopping on the Internet has a lot of advantages(网上购物有很多优点), of which the most important is perhaps its convenience. People don't have to waste a lot of their energy and precious time(浪费他们大量的精力和宝贵时间) to go from one shop to another to choose the commodities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person(亲自去商店). The goods come in all shapes, sizes and colors on the Internet. All they need to do is to sit in front of their computers and click the mouses(点击鼠标). The commodities they order will be delivered to them(送给他们) promptly.
However, shopping on the Internet also has its disadvantages(网上购物也有它的缺点). The first disadvantage is that the consumers can't see the goods or try them on personally(亲自试穿). Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered(没有注册).

虚拟语气(subjunctive mood)
是一种特殊的谓语动词形式,用来表示一种假设、愿望、建议、请求、命令、猜测、可能、空想等。如:
How I wish I were a bird!我多么希望我是一只小鸟!
I suggest you (should) go to have a walk.我建议你去散散步。
虚拟语气的应用
1. 用于条件句
1)条件句的从句和主句的谓语动词形式
条件从句 主 句
与现在事实相反 过去式(be的过去式一律用were )would/should/could/might+动词原形
与过去事实相反 had+过去分词 would/should/could/might+have+过去分词
与将来事实相反 should+动词原形
were to+动词原形 would/should/could/ might+动词原形
例如:
If I were you, I should do it.如果我是你的话,我就要做这件事。(与现在事实相反)
If he had come a few minutes earlier, he would have met me.如果他早来几分钟,他就见到我了。(与过去事实相反)
If you were to come tomorrow, I should ask you to help me with my work.如果你明天来,我就请你帮助我做这件工作。(与将来事实相反)
[注]此表可以灵活运用:
①用进行时替换相应的一般时,如用过去进行时代替一般过去时,表示与现在事实相反。
②用完成进行时替换相应的完成时,如用过去的完成进行时替换过去完成时,仍表示与现在事实相反。
如:
If it had been raining yesterday, I would not have come here.如果
昨天还在下雨的话,我就不会到这里来。
2) 虚拟语气谓语动词的形式一般不受主语的人称和数的影响,但主语的人称对主句中should和would的使用还是有一定影响。英国英语的第一人称常用should,其他人称用would;美国英语中,无论第几人称都常用would。情态动词could, might等除了可以用于主句外,有时也可以用于从句。
3) 混合型的条件句
按照条件句的谓语动词形式表,其主句和从句的谓语动词是相互呼应的,有着固定的搭配关系。但有时主句和从句的谓语动词并不是相互呼应,这种条件句叫做混合条件句, 又称为错综时间条件句。较多见的混合条件句是从句用过去完成时(指过去行为),主句用一般时(指目前状态)。如:
He would pass the test if he had taken my advice.如果他听了我的劝告,他现在会通过考试。
4) 虚拟条件句的省略情况
A.省略if的虚拟条件句:
如果虚拟条件句的谓语部分有were, had或should, 可省略if, 把were, had或should放到从句主语前面去。如:
Had you not helped me, I should have failed.要是没有你的帮助,我就失败了。
B.条件从句的省略
He could not fly (if he tried).(即使他试的话)他无论如何不能飞。
C.条件主句的省略
If only I had more money! 要是我有更多的钱就好了!
5) 表示虚拟条件句的其他形式
A.用介词without(或with no), but for 等表示“如果没有”。如:
But for air and water, nothing could live.要是没有空气和水,也就不能有生命。
B.用动词不定式、比较级、连词but等手段表示虚拟条件,还可以根据内容的需要来应用虚拟语气。如:
She would have come here, but she was too busy with her homework.她本来早就要到这儿来,但是她当时太忙于写作业了。
2.用于宾语从句
1)宾语从句在表示提议、要求、命令、意志等动词后,可用“should do”或“do型”(be原形动词)虚拟语气。这类动词有:suggest, request, demand, urge, propose, prefer, advise, insist, require, order, command, maintain, ask, object等。如:
The doctor suggested that he not go there.医生建议他不要去那里。
[注]学习这种句型时,要注意宾语从句的虚拟语气为固定形式,并不随主句谓语的动词时态的变化而变化。如:
We desire/desired/shall desire that he leave at once.我们要他马上离开。
2)宾语从句用在动词wish之后
A.过去式用来表示现在的愿望:“could/would/might+动词原形”用来表示将来的愿望,虽实现的可能性不大,但仍有实现的可能。如:
I wish it were true.我但愿这是真的。
B.“had+过去分词”或“could/would/might+have+过去分词”都是用来表示无能为力的过去愿望。如:
I wish you had called yesterday.我希望你昨天来过电话。
3)宾语从句在would, would/had rather后面,表示与事实相反的愿望,虚拟语气使用“did”型。如:
I would rather we went there together.我盼望我们一起去。
3.用于主语从句
1)“It +is +形容词+that引导的主语从句”句型,用动词原形或“should+动词原形”虚拟语气。常用于本句型的形容词有:necessary, important, impossible等。如:
It is necessary that she (should) listen to the radio frequently.她
很有必要常听收音机。
2)“It +is +过去分词+that引导的主语从句”,可用“(should)+动词原形”。常用于这一句型的过去分词有:suggested, required, requested, demanded, urged, ordered, proposed, desired, advised, etc. 例如:
It is ordered that we (should) go at once.命令我们立刻出发。
[注]在“It is (high) time + that 从句”结构中,用“did 型”虚拟语气,意为“(早就)到了做某事的时间了”。例如:
It is (high) time that you went to school.到了你上学的时间了。
4.用于表语从句和同位语从句
在suggestion, proposal, order, requirement, desire, decision, advice, plan, necessity等表示提议、要求、命令等名词的后面的表语从句和同位语从句中,可用“动词原形”或“should +动词原形”虚拟语气。如:
His suggestion is that the meeting (should) be put off.他的建议是推迟开会。
She made a proposal that we (should) go out for a picnic at the weekend.她提议周末出去野餐。
