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 specific laws that make spamming(發送垃圾郵件) a crime.

If lawmakers do not do something soon to prohibit 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, passes on to the consumer.

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.

57.What does the underlined word “correspondence” in the Paragraph 1 probably mean?                                                         

  A. messages     B. ideas          C. connections         D. programs

58. According to the text, what is the major cause of the flooding spam?    

  A. Companies rely on e-mail for communications.

B. More people in the world communicate by e-mail.

C. Many computer viruses contain spam e-mail.

D. More advertisers begin to promote sales through spam.

59. According to Paragraph 3, who is the final victim of spam?             

 A. The business                 B. The advertiser        

 C. The employee                D. The consumer

60. What is the purpose of the text?

       A. To inform                 B. To educate                C. To persuade                     D. To instruct

科目:高中英語 來源:2012-2013學年黑龍江友誼縣紅興隆管理局第一中學高二月考英語卷(帶解析) 題型:閱讀理解

Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear different home schooling teachers discuss history, I get the idea that there may be different reasons for teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons for studying history.
The major reason I see for studying history is that we can learn from the past. I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures. However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in teaching history, to my children I can do a small part in changing this.
A second major reason for studying history is that it is hard to understand the current political climate in the absence of an understanding of its historical context. We can not even understand why we are and where we are without history, much less (更不必說) try to figure out where we are going or how we should get where we want to be.
I teach my children history, for one more reason. I purchased a set of historical audio (錄音機) tapes for our children. My seven-year-old son listened to them over and over. It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr. if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for.
【小題1】The main purpose of this passage is to __________.

A.instruct the parents how to teach their children history
B.show the importance of history in politics
C.explain the reasons why children study history
D.introduce the writer’s own way of teaching history
【小題2】Which of the following is not the reason for studying history according to the author?
A.One can learn from history in order not to make the same mistakes.
B.It can help us to understand the current political climate.
C.Without history, one can be nothing but a fool in every aspect.
D.One can know the principle of doing something and not doing something.
【小題3】 Some positive historical figures are mentioned in the last paragraph to show __________.
A.people can be inspired to do good, while also learning to fight against evil
B.people may also learn from bad historical figures
C.more celebrations should be held to honor their achievements
D.today’s people can also achieve what they achieved
【小題4】 What would be talked about in the following paragraph?
A.How to teach history effectively.
B.Some negative reasons for studying history.
C.How to get more people to study history.
D.Some bad historical figures.
