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.
小題1:This passage is mainly concerned with ____________.
A. a way for treating AIDS

Words can hurt
I remember the pain most vividly. My stomach was sick, my heart hurt, and my eyes stung(刺痛的) from holding back tears.
“you know, Autumn,” my friend Nick said, “Lisa and Andrea were just talking about you.” I immediately got nervous. “They said that the only reason you start on the basketball team is because the coach (教練)likes you .It’s not because you’re good.” I might be sick. “They said they’re tired of you always getting what you want.”
I struggled to keep myself from crying, sinking(下沉) to my knees on the cold floor. After Nick told me everything my supposed best friends said about me, I was hurt.
Lisa and Andrea came in from lunch break acting as if nothing had happened . Lisa was still my deskmate, and Andrea was still my partner for our history project.
I was amazed at their ability to pretend we had the perfect friendship, especially since they’d said such hurtful things.
I was a freshman in high school, and I felt like I didn’t have a friend in the world, all because of a rumor(謠言).
The tongue can be our worst enemy. Rumors harm confidence(信心) and separate close friends. They are like sharp knives, cutting one’s dignity(尊嚴(yán)) into pieces. When we say unkind things about others, we’re thrusting(插) knives into their hearts.
So how was I to act next? When Lisa and Andrea pretended our friendship hadn’t changed, I thought of attacking them back. But instead, I told them directly that they had hurt me. Lisa started crying and Andrea was speechless. I know they were both sorry for what they had said. They apologized, and I forgave them with grace(優(yōu)雅). Sure, things were a little awkward(尷尬) at first, but soon enough everything was back to the way it had been before.
I still deal with gossip(流言), sometimes as a recipient(接受者) and sometimes as a participant(參與者). But the more I learn about love, the more I realize the importance of encouraging others- sometimes gossip never does.

Become a confident speaker. How to improve your English speaking skills and make you able to communicate more easily and effectively? The following tips will help you to become a more confident speaker.
Practice where you can and when you can. And practice is good — whether you speak to someone who is a native English speaker or not.
It’s important to build up your confidence. If possible, use the simple sentence structure that you know is correct, so that you can concentrate on getting your message across.
Try to experiment with the English you know. Apply (應(yīng)用) words and phrases you know to new situations. Native English speakers are likely to correct you if you use the wrong word. They usually don’t mind if you use wrong grammar.
Try to respond to what people say to you. You can often get clues to what people think by looking at their body language. Respond to them in a natural way.
Never translate everything into your own language. It takes you much time and you’ll find it difficult to find an English answer right away. You don’t know how to do well. The more you want to act well, the more slowly you act. This will make you hesitant.
If you forget a word, do what native English speakers do all the time, and say things that ‘fill’ the conversation. This is better than remaining completely silent. Try using ‘um’, ‘er’, if you forget the word.
Don’t speak too fast! It’s important to use a natural rhythm (節(jié)奏) in speaking English, but if you speak too fast it will be difficult for people to understand you.
Try to relax when you speak, and you’ll find that your mouth does most of the pronunciation work for you. Speak English at a normal speed.
Final tips: Try to become less hesitant. Don’t be shy to speak — the more you do it, the more confident you’ll become. Remember to be polite — use “please” and “thank you” if you ask someone to do something for you.
小題1:What is the text mainly about?
A.Good ways of studying English well.
B.Suggestions on becoming a confident speaker.
C.Things to pay attention to when speaking English.
D.How to correct your mistakes as you speak English.
小題2:How many tips does the author offer in this text?
A.9.B.10.C.11.D.12.
小題3:In this passage, the underlined word “hesitant” in the sixth paragraph means “________”.
A.sure about what to do

New York City schoolchildren can’t use cellphones at school because of Mayor Michael R. Bloomberg’s ban on cellphones in schools. Many parents are opposed to Mayor Michael R. Bloomberg’s ban on cellphones in schools by e-mail messages.
There was a 13-year-old student who was shot with a gun after school, unable to call his mother for help. There was a high school student robbed three times last year, twice in her school building. There was a girl who got a piece of glass placed in her eye during school and was saved from a possible cornea transplant (角膜移植) only because, having disobeyed the cellphone ban, she was able to call her mother and get an operation on time.
The ban has been on for years, but it set off a widespread parental outcry only in April, after some headmasters sent home letters reminding parents that cellphones are not allowed to be brought into school.
Mr Bloomberg has defended the ban, saying that cellphones are bad and often used to cheat or call in friends for fights. If something is important, he says, parents can call schools directly.
On the other hand, many of the e-mail messages from parents described the ban as “cruel and heartless”, “absurdly(荒謬地) wrong-headed”, “anti-parent”, “ridiculous”.
“We respect the fears that parents have,” David Cantor, a spokesman for Schools Minister Joel I. Klein said, “but after all the fact is that having phones in schools always leads to more problems.”
小題1:A 13-year-old student was shot with a gun after school, unable to call his mother for help, because ____.
A.his mother had no cellphone
B.his mother wasn’t at home
C.he didn’t take a cellphone with him
D.he was too frightened to call
小題2:From the fifth paragraph we can see many parents _________ the ban.
A.a(chǎn)greed toB.thought highly of
C.supportedD.were opposed to
小題3:According to what the spokesman said, the school might _______.
A.call off the ban
B.continue the ban
C.thank the parents
D.a(chǎn)llow some students to use cellphones at school

Writer and teacher Yin Jianli's stories and thoughts about bringing up her daughter
Yuanyuan have been a constant source of inspiration for parents over the past 16 years.
Her book,  A Good Mother Exceeds Good  Teachers,  published  by  Writers Publishing House, has been a bestseller on Dangdang and Amazon's online platforms
for the past three years.  The book helped Yin make the Chinese Writers' Rich List, with 4. 48 million yuan($710,000).
Experts say Yin's book provides practical guidance, which makes it popular among parents.
"When the majority of books are either full of bragging about(自吹自擂)the authors' children or outlining big theories that have no foundation in practice, I write books that are practical and easy to follow," Yin writes.
"For example, there was an occasion when Yuanyuan forgot to do her elementary school homework.  In such a situation many Chinese parents show their anger and scold their kids,”says Yin, who made an agreement with her husband they would not overly criticize or push their daughter.  Instead, Yin encouraged the daughter to make up the homework, which meant staying up until midnight.  As a result,  she learned to arrange her time better and did not have a harmful reaction to doing homework.  Yin's principle of "no parental interference(干涉),and "giving children the opportunity to learn from their mistakes" is described in a number of real-life examples.
Readers say Yin's books improve their children's performance at school,  and encourage them to develop good personalities and habits.  They believe her books are not only about being good parents but also about growing as parents and individuals.
"When I'm reading books,I keep thinking about what a better personality I would have if my parents had adopted the methods Yin suggests when I was a kid,"one reader comments in a review on Yin's online blog.

Going Zero Waste means more than dealing with the rubbish we create. It means reducing it, too. People who go Zero Waste are careful about what they do. They never take more than they need, they reuse plastic bags, and they make good plans not to buy more than necessary before going shopping.
Kamikatsu, a Japanese village, has already gone Zero Waste. The 2,000 villagers recycle everything possible. There are 34 different boxes at the recycling center! The villagers sometimes just feel unhappy about what they have to do, but they also see the good side.
