Most animals have little connection with animals of different kind, unless they hunt t

hem for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.

Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals (珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe.

Many 1anguage learners fail to realize that when they listen to their native Language th

ey do not actually hear every word.They also fail to understand that they integrate their knowledge about language with their experience and knowledge of such things as topic and culture, and do not need to hear to hear every word. This means that learners Often have unrealistic expectations and try to understand each word Of a listening text. As some experts point 0ut，“such total comprehension…is a misconception 0f how normal comprehension works in the native language.” Learners’anxiety may get worse when a classroom procedure does not provide adequate context for the text Or prepare the topic by activating their prior knowledge;in Other words，a procedure which asks students to“Listen to the text and then answer the questions.” This tests listening ability rather than aiming to teach it.Adults returning to English language learning whose earlier experiences have been of this nature may have developed negatlve perceptions 0f their ability as 1isteners and a maior task for the teacher will be to build confidence. This means recognizing anxiety and a major tasking care to provide positive classroom experiences.For example，the teacher needs to make sure that the pace and length of a 1istening activity is not too taxing as the concentration required in trying to cornprehend unfamliliar sounds can be tiring.

第4题

Few creations of big technology capture the imagination like giant dams. Perhaps it is hum

ankind's long suffering at the mercy of flood and drought that makes the ideal of forcing the waters to do our bidding so fascinating. But to be fascinated is also, sometimes, to be blind. Several giant dam projects threaten to do more harm than good.

The lesson from dams is that big is not always beautiful. It doesn't help that building a big, powerful dam has become a symbol of achievement for nations and people striving to assert themselves. Egypt's leadership in the Arab world was cemented by the Aswan High Dam. Turkey's bid for First World status includes the giant Ataturk Dam.

But big dams tend not to work as intended. The Aswan Dam, for example, stopped the Nile flooding but deprived Egypt of the fertile silt that floods left—all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.

And yet, the myth of controlling the waters persists. This week, in the heart of civilized Europe, Slovaks and Hungarians stopped just short of sending in the stoops in their contention over a dam on the Danube. The huge complex will probably have all the usual problems of big dams. But Slovakia is bidding for independence from the Gzechs, and now needs a dam to prove itself.

Meanwhile, in India, the World Bank has given the go-ahead to the even more wrong-headed Narmada Dam. And the bank has done this even though its advisors say the dam will cause hardship for the powerless and environmental destruction. The benefits are for the powerful, but they are far from guaranteed.

Proper, scientific study of the impacts of dams and of the cost and benefits of controlling water can help to resolve these conflicts, Hydroelectric power and flood control and irrigation are possible without building monster dams. But when you are dealing with myths, it is hard to be either proper, or scientific. It is time that the world learned the lessons of Aswan. You don't need a dam to be saved.

The third sentence of Paragraph 1 implies that ______.

A．people would be happy if they shut their eyes to reality

B．the blind could be happier than the sighted

C．over-excited people tend to neglect vital things

D．fascination makes people lose their eyesight

第5题

Few observers have a better view of that ocean of exchanging gossip called E-mail than Mar

k Sunner. The chief technology officer of E-mail management company MessageLabs, Sunner oversees a network that processes 4.5 million letters each day. Servers operated and maintained by MessageLabs manage mail delivery and routing for a number of companies, including Bank of England and Condé Nast Publications. In fact, all of MessageLabs’ customers are corporations whose daily E-mail output and inflow has soared with the growth of the Web. “E-mail usage has increased massively in the last couple of years,” he says. Indeed, MessageLabs estimates that it has gone from 10 a day per employee as recently as two years ago to more like 20 or 30 now.

The implications for Corporate America are equally huge. According to E-mail researcher and consultant David Ferris, companies can expect the volume of E-mail coursing through their servers to grow 60% to 80% in 2002. And as individual messages grow in size - they’re now more likely to contain memory - companies could end up paying 100% to 150% more just this year on systems to store and manage those messages. That’s why tech consultancy Radicati Group expects demand for soft ware that manages E-mail, such as Microsoft Outlook and Lotus Notes, to grow from $2.6 billion in sales today to $4.4 billion by 2005. Too much of this money will be spent in controlling pure junk. About 20% of the E-mail MessageLabs manages is unwanted, according to Sunner - who adds that about 1.25% of all the E-mail his company moves contains useless attachments. Already, the cost of handling spam（垃圾邮件）is estimated at $8.6 billion worldwide, according to a 2001 European Union study. And the barrage of pornographic spam has made some companies worried that employees might sue on grounds of disturbance arising from exposure to unwanted unpleasantness.

The first sentence of this passage “Few observers have a better view of that ocean of exchanging gossip called E-mail than Mark Sunner” most probably means ____.

A.Mark Sunner clearly know the E-mail is wasting resources

B.no one knows the fact that E-mail is gossip exchanging way but Mark Sunner

C.Mark Sunner does not know anything about the E-mail

D.the Mark Sunner always concentrated on the ocean of the junk E-mail

Which of the following is NOT true about MessageLabs？A.It is an E-mail management company.

B.All of MessageLabs’ customers are corporations.

C.Mark Sunner is the chief technology officer of MessageLabs.

D.The company puts the great emphasis on dealing with the junk E-mail.

The word “that” in the last sentence of the third paragraph most possibly means ____.A.it is expected that Microsoft Outlook and Lotus Notes grow from $2.6 billion in sales today to $4.4 billion by 2005

B.the junk E-mail has been overloaded in the Internet

C.the increase of individual messages needs more staff

D.the company has paid 100% to 150% for individual message storage

What is the best title for the passage？A.The E-mail Monster.

B.MessageLabs Business Introduction.

C.To Avoid E-mail Surge.

D.E-mail Destroys Everything.

The following statements about the E-mail have been mentioned EXCEPT ____.A.Sunner oversees a network that processes 4.5 million letters each day

B.according to David Ferris, companies can expect the volume of E-mail passing through their servers to grow not more than 50% in 2002

C.too much money has been spent in controlling the junk E-mail

D.some employees might take legal action in accordance with annoyance arising from exposure to some unpleasant resources
