I am sure that everybody in his／her life has used computers．Nowadays you can feel their presence everywhere—at home，at school，at work and they certainly make life easier．On the other hand，there are people who can work without them．
Anyway, I believe their presence is a good thing．Life with them seems less difficult and more comfortable．You can use them to choose your meal，to withdraw your money，and also to save your time，because these operations ale all controlled by computers．Therefore，you can hardly imagine the modern world without them；the whole planet seems to be one big computer society．
Nevertheless，problems call often appear in this area，too．To have a computer means you have to be quite rich and have the necessary skills to use it．However, think about questions like，“Are computers available for everyone, for rich and poor people，for people from villages and people from cities? Aren’t they too expensive? Is everyone able to learn how to use them and does everyone have the chance to access and work with them? How could everything in the future be dependent on them?”Therefore，I think our society will be divided into two pans．One part will work with them and enjoy the benefits that computers can bring and the other part will be pushed out of society and will actually be left far behind the other group．
Another question that bothers me is，computers are important and they’re good things in our life, but they aren’t everything. They are good as a help at school, quite often as entertainment, especially for young people, as an necessary tool to help in research etc. , but I think we shouldn’t be so dependent on them, because computers are only machines and machines can’t feel anything, can’t be human and sympathetic, and every action performed by computer can be interfered(干涉) with could cause these machines to crash or work badly.
In conclusion, I would like to say I am not against computers. I use computers too, but people should be wary all the time.

An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients’ life.Called the Biologic-HT System, the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body. The heated blood causes the patient’s body temperature to rise above 42 degrees Celsius. In people with AIDS, that increase in temperature kills some heat-sensitive HIV, the virus, most doctors say, causes AIDS.
Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects.
The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn’t kill all traces of the virus. However, it kills enough virus particles to give a patient’s immune system a reprieve in its deadly duel with HIV.
Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning.
So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections—disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV.This passage is mainly concerned with ____________.
| A． a way for treating AIDS |
| B． a heat-sensitive virus |
| C． the immune system of the human body |
| D． the function of high temperature |
The blood of the patient___________.

The previous attempts to use high temperature for treating AIDS failed because they_________.
| A．caused chemical changes |
| B．could not kill HIV effectively |
| C．resulted in deaths |
| D．killed both HIV and healthy cells |
According to the passage, the new treatment___________.
| A．can kill all the HIV viruses |
| B．cannot eliminate the viruses completely |
| C． can double the number of disease-fighting cells |
| D．can reconstruct the patient’s immune system. |
The result of the experiment seems to be ___________.

It is easy to find your way about in New York. It is laid out so regularly. Instead of streets winding and twisting (迂回) as they do in London, they are all regular and well planned. The streets running north and south are called “avenues” and are numbered, e.g. 1st Avenue, 2nd Avenue, etc. The streets going east and west are called “streets” and are also numbered, e.g. 51st Street, 63rd Street. It is all much more logical (合理的) than London’s street names. But I couldn’t help thinking how much more interesting than these dull cold numbers are London’s illogical but colorful names of streets, e.g. “Bishopgate” (which is not a gate and hasn’t a Bishop in it); “Haymarket” or “Corn market” (where you won’t see any hey or corn) or “Poultry” (without a living chicken anywhere in sight) or “Thread needle Street” (where you won’t find little girls learning to sew).In the second sentence of the passage, “laid out” means ______.
| A．built | B．be put | C．designed | D．cut down |
The streets running from north to south are called _______.
| A．avenues in London | B．streets in America |

The Centers for Disease Control and Prevention (CDC) recently announced trends in fruit and vegetable consumption(食用) among adults. Since 2000, the CDC has made efforts with goals of getting 75% of Americans to eat two or more servings of fruit a day and 50% of Americans to eat three or more servings of vegetables a day. Unfortunately, Americans aren’t meeting these modest targets.
Although a diet high in fruit and vegetables can reduce the risk of many diseases, Americans just aren’t getting enough. In fact, since 2000, the amount of vegetables Americans are eating has stayed the same and the amount of fruit Americans are eating has gone down. The CDC also finds that only about a third of adults are eating their expected servings of fruit, and just over a quarter of adults are eating their expected servings of vegetables.
So why aren’t Americans getting their expected servings of fruit and vegetables? It turns out that Americans might be spoiled when it comes to their produce. A national survey conducted by Fruit2day reveals that nearly half of Americans leave fruit in their fridges until it rots with people in Boston among the worst and those in New York and Los Angeles among the best. Sadly, most Americans admit to leaving fruit in the fridge for more than a week.
There are many reasons why Americans don’t eat their fruit or vegetables, including the inconvenience of having to wash or peel it. Fruit2day offers consumers a surprising and convenient way to enjoy the goodness of fruit.
“With no added sugar, natural juices and two full servings of fruit, our Fruit2day line has really captured the imaginations of health-conscious consumers who are actively looking to get more fruit in their diets,” said Hanno Holm, president and chief executive officer of Hero-White Wave. “Fruit2day makes getting more fruit in one’s diet easier for any daily snack routine.”For 4 million American adults, how many of them are eating two or more servings of fruit a day?
| A．About 1.3 million. | B．About 2 million. | C．About 3 million. | D．About 1 million. |
We can learn from the first two paragraphs that __________ .
| A．Americans have been eating fewer vegetables since 2000. |
| B．most Americans eat less fruit to reduce the risk of diseases. |
| C．most Americans prefer fruit to vegetables. |
| D．over 25% of adults are eating three or more daily servings of vegetables. |
In which city are people most likely to leave fruit in their fridge?
| A．In Boston. | B．In New York. | C．In Los Angeles. | D．Not mentioned. |
With the help of Fruit2day, Americans can __________ .
| A．easily get rid of their bad eating habits |
| B．conveniently have more fruit in their diets |
| C．add sugar and natural juices to their diets |
| D．find another excuse for not eating healthily |
Americans don’t eat their fruit or vegetables because __________ .
| A．they are relatively forgetful |
| B．they are too busy with their work |
| C．they don’t think it convenient to eat them |
| D．they prefer daily snacks with added sugar |
To us it seems so natural to put up an umbrella to keep the water off when it rains, but actually the umbrella was not invented as protection against the rain, Its first use was as a shade against the sun!
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese in the 11th century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in commonly used in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered as a symbol of power. By 1680, the umbrella appeared in France and later in England.
By the eighteenth century, the umbrella was used against rain throughout most of Europe.
