20.Stop Spam!
When I first got an e-mail account ten years ago,I received communications only from family,friends,and colleagues.Now it seems that every time I check my e-mail,I have an endless series of advertisements and other correspondence  that do not interest me at all.If we want e-mail to continue to be useful,we need laws that make spamming (發(fā)送垃圾郵件) a crime.
If lawmakers do not do something soon to prohibit (禁止) spam,the problem will certainly get much worse.Computer programs allow spammers to send hundreds of millions of e-mails almost instantly.As more and more advertisers turn to spam to sell their products,individual (個人的) e-mail boxes are often flooded with spam e-mails.Would people continue to use e-mail if they had to deal with an annoying amount of spam each time?
This problem is troubling for individuals and companies as well.Many spam e-mails contain computer viruses that can shut down the entire network of a company.Companies rely on e-mail for their employees to communicate with each other.Spam frequently causes failures in their local communications networks,and their employees are thus unable to communicate effectively.Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks.These computer problems raise production costs of companies,which are,in the end,passed on to the consumer(消費者).
For these reasons,I believe that lawmakers need to legislate (立法) against spam.Spammers should be fined,and perhaps sent to prison if they continue to disturb people.E-mail is a tool which helps people all over the world to communicate conveniently,but spam is destroying this convenience.

28.What does the underlined word"correspondence"in the Paragraph 1probably mean?C
A.connections        B.ideas       
C.messages           D.programs
29.According to the text,what is the major cause of the flooding spam?B
A.Companies rely on e-mail for communications.
B.More advertisers begin to promote sales through spam.
C.Many computer viruses contain spam e-mails.
D.More people in the world communicate by e-mail.
30.According to Paragraph 3,who is the final victim(受害者) of spam?B
A.The business. B.The consumer.
C.The employee. D.The advertiser.
31.What is the purpose of the text?A
A.To persuade.
B.To educate.
C.To introduce.
D.To instruct.

分析 隨著越來越多的廣告商轉(zhuǎn)向垃圾郵件來銷售他們的產(chǎn)品,個人郵箱里經(jīng)常充斥著垃圾郵件.本文主要講述的是垃圾郵件的危害,目的在于說服立法機構(gòu)設(shè)立相關(guān)的法律禁止垃圾郵件的泛濫.

解答 28.C 推理判斷題.根據(jù)本句I have an endless series of advertisements and othercorrespondence that do not interest me at all.可知,我有一系列沒完沒了的廣告和其他我根本不感興趣的"correspondence".所以correspondence是與前面的advertisements相似的內(nèi)容,即A選項的"信息",兩者都屬于我們的郵箱里不想要的東西,故C正確.
29.B 細節(jié)理解題.根據(jù)第二段的As more and more advertisers turn to spam to selltheir products,individual (個人的) e-mail boxes are often flooded with spam e-mails.可知,隨著越來越多的廣告商轉(zhuǎn)向垃圾郵件來銷售他們的產(chǎn)品,個人郵箱里經(jīng)常充斥著垃圾郵件.所以垃圾郵件的主要原因是廣告商使用垃圾廣告來宣傳產(chǎn)品.故B正確.
30.B 細節(jié)理解題.根據(jù)第三段最后一句的These computer problems raise production costs ofcompanies,which are,in the end,passes on to the consumer可知,這些計算機問題提高了企業(yè)的生產(chǎn)成本,最終將這些成本傳遞給消費者.所以最終的受害者是顧客.故B正確.
31.A 主旨大意題.本文主要講述的是垃圾郵件的危害,目的在于說服立法機構(gòu)設(shè)立相關(guān)的法律禁止垃圾郵件的泛濫.故A正確.

點評 本文是社會文化閱讀,主要考查細節(jié)理解題和推理判斷題.在做細節(jié)理解題時,首先根據(jù)題目要求迅速在文章里找出相應(yīng)的段落、句子或短語.認真比較選項和文中細節(jié)的區(qū)別,在做推理判斷題時不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.

10.Allow me to introduce you to Terry,a window salesman from England.If I could take you back about 20 years,you'd know Terry as a complete green hand,who was wet behind the ears in just about everything he attempted.A person couldn't sell false teeth to his own Granny,let alone he could compete with the other salespeople in the industry. You know,the kind who could sell snow to Eskimos.
Terry's boss decided to send him out on a practical field trip on his first day.So off he went,but he was extremely nervous.With his hands and his knees shaking,he approached the front door and knocked at is.And old woman appeared.After dozens of cups of tea and pieces of biscuits,the woman signed a contract and purchased over $7,000 worth of windows.
The woman had already talked with 6 excellent salesmen that week,all of whom offered her cheaper ones!That's right---Terry's price was the most expensive and he was also the most inexperienced salesman there ever was.
So,what happened then?Here comes the secret.The woman said she liked the young lad more than the others.That's all there was to it.She didn't care about the extra expense.Even the other salesmen couldn't persuade her to pay less than this young lad was asking for.
The truth is that the young lad left on the woman the first impression that shone brighter than any of the salesman's talk.First impressions count,not the sales techniques,not the low prices.The actual"personality"the kid honestly gave was all that was required.If you market your own products and services,consider what impression you are giving to others.If you appeal to them,then you've already done half of the work.If this means redesigning your presentation,then so be it.If this means going out of your way to be polite,helpful and giving the best possible shopping experience to your customers,the so be it.
21.When Terry was offered the job of salesman,heD.
A.was good at sales techniques
B.was too young to do it

A.Terry couldn't trade with Eskimos
B.Terry loved his Granny more
C.Terry was too honest to do the job
D.Terry was afraid to compete
23.What made the young lad succeed in selling t he window to the old woman?B

C.High quality and expensive window.
D.Strange ways of sales.
24.The passage is most likely written toA.
A.new salesmen
B.general readers
