From E-mail to online shopping, you may think you’ve heard everything there to know about the electronic frontier (新领域).But with hundreds of thousands of Web pages being added weekly, there are plenty of surprises out there.Here are some of the most intriguing (有迷惑力的).

……

Put your kid on a greeting card.Here is how: simply take some pictures with a regular camera, and then ask the photo service to develop them digitally (数字化).For a small fee, you’ll receive your photos on a desk.Put that into your computer and, with a few clicks of the mouse, you can view your photos on the screen.With a few more keystrokes, you can attach the photos to email and send them to friends and relatives worldwide.

  Sign on to one or several greeting card’s Websites (http://www.cardcentral.net/ is an index of more than 1200 electronic card sites) and create an electronic birthday or holiday card.Using your digital photos, you can paste your grandchildren onto the cover.

  If you don’t want to use your own photos, go to cards.amzon.com to browse (浏览) hundreds of images in over 30 categories…all of which you can attach to an electronic greeting card for free.For a nominal fee(很低的费用)you can choose from a library of 75,000 images at http://www.phontodisc.com/.

  Call Australia for free.To have a telephone conversation over the Internet, the person you want to talk to no longer needs a computer.Now all you need to talk to someone in Sydney is one computer with speakers, a microphone, a sound card and some software (available at http://www.vocaltec.com/ or Mricrosoft.com).Typically, you’ll pay a monthly fee (usually under $20) to a service provider, but after that, the calls themselves are local.Sound quality is the same as that of a cell phone.

  Even if you don’t have a computer, you can still use the Web to reduce your long distance phone costs.Some companies offer a service that lets you use an ordinary phone to call another ordinary phone, but charge only a few cents per minute for US calls, because they send them through the Internet.

  Today 48 percent of American homes have computers…a figure that is expected to climb to 60 percent by 2003.And by the end of the next decade, Americans will likely be spending more time shopping, banking, investing and learning on the Internet than in the real world.If you can’t do or find something on the Net today, you probably can tomorrow.

60.Over the Internet, you ________.

       A.can hear everything there

       B.will meet with plenty of surprises which come out every week.

       C.will hear the things about the electronic frontier

       D.can find some things are very interesting

61.From the passage we can infer that _________.

       A.fewer people will use the Internet in the following ten years

       B.more people will study in the regular school by the end of the next decade

       C.fewer people will go to the regular school in the following ten years

       D.more money will be needed for a long-distance call by the end of the next decade

62.If you want to attach to photo to your e-mail, you have to ________ it.

       A.digitalize    B.take       C.picture          D.send

63.Which of the following is NOT true?

       A.A telephone conversation over the Internet can be carried out without computers.

       B.Over the Internet, the receiver of the phone conversation doesn’t need a computer.

       C.The phone conversations over the Internet are much cheaper.

       D.The long-distance calls are local themselves.

A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower.

A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic, but overtime it can break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow. “We’ve only put sunflower seeds into the cover so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time.” said one scientist.

As phone technology is developing so quickly people are constantly throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. “The seed is released and the flower grows in the pot so you don’t have to concern yourself with the phone when you have finished using it,” said Kerry Kirwan, the leader of the research team.

After you have finished using the new type of mobile phone, _______.

A. the sunflower seed will come out and flower in the pot

B. the phone cover will break down very soon in the soil

C. it will be recycled by the producers

D. it can charge itself with electricity in a green way

This type of research is done because ________.

A. the technology of making phones is changing rapidly

B. too many waste mobile phones may lead to environmental problems

C. nobody has ever thought of recycling mobile phones

D. producing mobile phones uses a lot of energy

We can infer from the story ________.

A. the new type of mobile phones are already on the market

B. the new type of mobile phones will sell extremely well

C. the material of the new type of phones is harmful

D. other flowers may be used in the new type of mobile phones

The best title of this passage is           .

A. Recycling our phones

B. The phones that flower

C. A new material for making phones

D. The harm of thrown-away phones

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.Without the forest cover,these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world.

    In the past hundred years,humans have begun destroying rainforests in search of three major resources(资源): land for crops,wood for paper and other products,land for raising farm animals.This action affects the environment as a whole.For example,a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests.People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

    There are two main reasons for this.Firstly,when people cut down trees,generally they can only use the land for a year or two.Secondly,cutting large sections of rainforests may provide a good supply of wood right now,but in the long run it actually reduces the world’s wood supply.

    Rainforests are often called the world’s drug store.More than 25% of the medicines we use today come from plants in rainforests.However,fewer than l%of rainforest plants have been examined for their medical value.It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

Rainforests can help to adjust the climate because they                

  A.reflect more heat into the atmosphere

  B.bring about high rainfall throughout the world

  C.rarely cause the temperature to drop lower than l6℃

  D.reduce the effect of heat from the sun on the earth

What does the word “this” underlined in the third paragraph refer to? 

  A.We will lose much more than we can gain.

  B.Humans have begun destroying rainforests.

  C.People have a strong desire for resources.

  D.Much carbon dioxide comes from burning rainforests.

It can be inferred from the text that      

  A.we can get enough resources without rainforests

  B.there is great medicine potential in rainforests

  C.we will grow fewer kinds of crops in the gained land

  D.the level of annual rainfall affects wind patterns

What might be the best title for the text? 

   A.How to Save Rainforests                B.How to Protect Nature

   C.Rainforests and the Environment        D.Rainforests and Medical Development

A

A higher reading rate, with no loss of comprehension, will help you in other subjects as well as in English, and the general principles apply to any language. Naturally, you will not read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook-but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage gained will be the same whatever kind of reading you are concerned with.

The reading passages which follow are all of an average level of difficulty for your stage of instruction. They are all about five hundred words long. They are about topics of general interest which do not require a great deal of specialized knowledge. Thus they fall between the kind of reading you might find in your textbooks and the much less demanding kind you will find in a newspaper or light novel. If you read this kind of English, with understanding at four hundred words per minute, you might skim (浏览) through a newspaper at perhaps 650-700, while with a difficult textbook you might drop to two hundred or two hundred and fifty.

Perhaps you would like to know what reading speeds are common among native English-speaking university students and how those speeds can be improved. Tests in Minnesota, USA, for example, have shown that students without special training can read English of average difficulty, for example, Tolstoy's War and Peace in translation, at speeds of between 240 and 250 words per minute with about seventy percent comprehension. Students in Minnesota claim that after twelve half-hour lessons, once a week, the reading speed can be increased, with no loss of comprehension, to around five hundred words per minute.

According to the passage, the purpose of effective reading with higher speed is most likely to help you ________.

A. only in your reading of a physics textbook

B. improve your understanding of an economics textbook

C. not only in your language study but also in other subjects

D. choose the suitable materials to read

Which of the following does not describe the types of reading materials mentioned in the second paragraph?

A. Those beyond one's reading comprehension.

B. Those concerned with common knowledge.

C. Those without much demand for specialized knowledge.

D. Those with the length of about five hundred words.

The average speed of untrained native speakers in the University of Minnesota is ________.

A. about 300 words per minute

B. about 245 words per minute

C. about 650-700 words per minute

D. about 500 words per minute

According to the passage, how fast can you expect to read after you have attended twelve half-hour lessons in the University of Minnesota?

A. You can increase your reading speed by three times.

B. No real increase in reading speed can be achieved.

C. Yon can increase your reading speed by four times.

D. You can double your reading speed.

A small man with a fat stomach got on the train at the last station before the frontier (边境). He carried a paper bag. And four feet ducks could be seen under the cover. The man found an empty seat, put the bag in the middle of the floor, took out a newspaper and began to read. Then a policeman came in. Of course he saw the bag with ducks' legs at once and said, "Whose is that bag?" Nobody answered. The policeman repeated the question, and said, "I'll have to take it away from the owner. Food mustn't be taken out of the country." "Well, then," said the small man with a fat stomach. "Hurry up and take it. We want to go home." The policeman took the bag and went on to the next carriage.

At the next station, when they were safely across the frontier, the small man got up, smiled at the other passengers and said, "I hope they'll enjoy the ducks' feet. The rest of the bag had nothing but rubbish in it." Then he opened his coat and pointed to another bag he was carrying under it. It was tied tightly (紧紧地) over the stomach, which was not really fat. "I have the rest of the two ducks here," he said. With these words, he got off the train.
