题型：不详难度：来源：
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 dictionary tells you about English words and how to use them in reading, writing and speaking English. It not only gives the meaning of words, it can also help you with spelling, word-building, grammar and pronunciation.
To use your dictionary correctly, you need to understand how the dictionary works. At the front of the book, you will find some exercises to help you make the most use of your dictionary.
If you look up the word “colour”, you will find two spellings for this word. “Colour” is used in British English, while “color” is used in American English. When there are differences between British and American spelling, the dictionary shows it with the word “BrE” for British English and “AmE” for American English.
The dictionary also helps you pronounce words correctly. We use a special alphabet (特殊字母) to show pronunciation. If you turn to the inside back face, you will see all the phonetic letters (音标) with some words to show you how they are pronounced. Just look at the inside back cover when you’re not sure how to say a word.
The most important reason for using a dictionary is to find out the meaning of a word—its definition
In this dictionary, the definitions have been written using only 2000 words. This means that the definitions of even the most difficult words are simply explained and easy to understand.

Due to the increasing number of violent acts produced in schools all over the world, more and more parents prefer to have their children educated at home rather than at school. This way they can assure their safety and well-being. Teachers and school representatives are trying to improve the situation in schools by increasing the number of the persons charged with the safety of the students.
The main reason for violent acts are the films and cartoons that fill the children’s time. They want to do everything. They watch on TV and never think of the results, and they may hurt a classmate or a teacher.
On the other hand, parents are not fully satisfied with the children’s results obtained in classes and they consider private classes would have better results.
When a teacher has to watch 30 students in class he can’t probably see what each of them is doing, how he is writing, or if he understands the explanations. At home the teacher can explain in detail everything the child doesn’t understand as many times as he considers proper.
And many times, the child grows fond of the teacher at home, who becomes his best friend, and who helps him whenever he needs someone to talk to.
However, the best solution would be a mixture between the education received at school and that at home, because school makes children communicate and socialize. Keeping a child at home for fear that something bad might happen to him only makes the child’s character weak and prevents him from knowing what real life is. Staying in a glass bowl only does harm to the child.
All in all, schools have been created to help children, not to harm them, so it’s best to keep children in these special places, where they learn, laugh, have fun and make new friends.
小题1:The writer’s purpose in writing the text is to .| A．teach parents the ways to keep theft children safe | | B．show solutions to developing children’s character | | C．explain the main reason for violence acts in schools | | D．analyze an education problem and give opinions. |
小题2:What does “a glass bowl” in the passage refer to?| A．A toy that can be used for entertainment． | | B．A safe and comfortable environment． | | C．An object that is made of crystal． | | D．A setback that is hard to overcome． |
小题3:We can infer from the passage that .| A．violent TV programs have bad effects on children’ behavior | | B．the teacher at home is more patient than the teacher at school | | C．children today are weak from lack of sense of right and wrong | | D．there are too many students in class for a teacher to teach |

Just listen
I suspect that the most basic and powerful way to connect to another person is to listen. Just listen. Perhaps the most important thing we ever give each other is our 36 , and especially if it’s given from the 37 . When people are talking, there’s no need to do anything but 38 them. Just take them 39 . Listen to what they’re saying. Care about it. Most times caring about it is even more important than 40 it.
One of my patients told me that when she 41 to tell her story, people often 42 to tell her that they had once had something just like what happened to her. Subtly, her pain became a story about themselves. 43 she stopped talking to most people. It was just too 44 . We connect through listening. When we interrupt what someone is saying to let them know that we understand, we move the 45 of attention to ourselves. But when we listen, they know we care.
I have ever learned to 46 to someone crying by just listening. In the old days I used to reach for the tissues(纸巾) 47 I realized that passing a person a tissue may be just another way to shut them 48 , to take them out of their 49 of sadness and pain. Now I just listen. When they have cried all they need to cry, they find me there 50 them.
This 51 thing has not been that easy to learn. It certainly went against everything I had been 52 since I was very young at school. I thought people listened only because they were too 53 to speak or did not know the answer. A loving silence often has far more 54 to connect than the most well-intentioned(善意的) 55 .

Once my mother told me a story that in Africa, when an antelope (羚羊) wakes up every morning, the first thing it thinks about is, “I must be 36 to run faster than the fastest lion, or I will be killed.” 37 , a lion wakes from his dream. The first thing the lion thinks about is, “I must be able to catch the 38 antelope, or I will starve to 39 .” So almost simultaneously(同时地), the antelope and the lion get up and start running toward the 40 sun.
This is 41 : full of chances and challenges. Whether you are an antelope or a lion, you must go 42 when the sun rises. For students, it is just the same. If we don’t study hard, sooner or later, we will 43 the other students. At first I didn’t know what the word “exam” 44 . Later, I knew an exam was a kind of 45 . In competitions, there are always winners and 46 . As I grew up, I got to know competition well. In one’s life, there must be competitions, so people can 47 .
Each time I saw children playing games and heard their 48 , I wished I were that age again. 49 , I remembered my parents’ words: You must work very hard for a good future. So I 50 my pen and began to study hard again.
I was still not sure what competition 51 meant. One day, I was 52_in an English-speaking competition. When I went to the stage, I saw other students looking at me kindly. Suddenly I 53 what competition was. It is not as cruel as my teacher and parents told me. In fact, competition is the 54 : it is kind and necessary.
I learned a lot from realizing this 55 . Now I understand better about the world. Competition is important for us all.
