AIDS is the fifth leading cause of death among persons between ages 25 and 44 in the United States. About 47 million people worldwide have been infected with HI~ since the start of the epidemic.
AIDS stands for "Acquired Immune Deficiency Syndrome". It is caused by the Human Immunodeficiency Virus(HIV). AIDS is the final and most serious stage of HIV disease, in which the signs and symptoms of severe immune deficiency have developed.
HIV has been found in saliva, tears, nervous system tissue, blood, semen, vaginal fluid, and breast milk. However, only blood, semen, vaginal secretions, and breast milk have been proven to transmit infection to others.
Transmission of the virus occurs through sexual contact, blood transfusions or needle sharing, and from mother to child. A pregnant woman can passively transmit the virus to her fetus, or a nursing mother can transmit it to her baby.
Other transmission methods are rare and include accidental needle injury, artificial insemination through donated semen, and through a donated organ.
HIV infection is not spread by casual contact such as hugging and touching, by touching dishes, doorknobs, or by mosquitoes. It is not transmitted to a person who donates Blood or organs. However, it can be transmitted to the person receiving blood or organs from an infected donor. This is why blood banks and organ donor programs screen donors' blood and tissues thoroughly.
How many people worldwide have been infected with HIV since the start of the epidemic?
A.47 million.
B.4 billion.
C.25 million.
D.44 million.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
Did you know that only the female mosquito bites? Well, it's true. And it's not because she's un friendly; she needs blood to reproduce.
She's quite selective, and she chooses her victims carefully. First, she uses sensors to find her victim. These sensors are located on her two antennae and her three pairs of legs. With these sensors, she tests your body moisture, body warmth, and chemical substances in your sweat. If she likes what she finds, she bites. But if you don't appeal to her, she'll reject you for some one more appetizing.
If the mosquito likes you, she settles onto your flesh very gently, and she breaks your skin with the tip in front of her nose. This tip is a kind of mouth and it sticks out just below the mosquito's eyes. It contains six sharp instruments called stylets. She stabs all six stylets into your skin at once, and if she hits a blood vessel, she'll get a full dinner in about a minute. All this usually takes place too quickly and quietly that you may not have suspected anything was happening.
Why does your skin itch after the mosquito bites? The itch is not really from the bite. It is from the liquid the mosquito mixes with your blood to keep it from forming into lumps as she sucks it up her proboscis tip. By the time the itching begins, she has gone. Heavy with your blood, she picks a spot--on a leaf or a wall or a stone--to quietly lay her eggs. Just one drop of blood will produce hundreds of eggs.
All mosquitoes, male and female, pass through their early stages of development in or near water. In fact, mosquito eggs will not hatch without water--although the eggs can survive up to five years on dry land waiting for water. It is not surprising that the heavy rain produce large numbers of mosquitoes.
Why did nature bother to create mosquitoes? Just to annoy us? Probably that wasn't the main reason. Male mosquitoes live on the juice of flowers, and they never bite people since they do not need blood to reproduce as the female ones. Of course, mosquitoes have to reproduce, and unfortunately that's where you and I come in. Like it or not, mosquitoes are here to stay.
The female mosquito bites because
A.she is unfriendly.
B.she needs blood to produce the young.
C.she is selective in food.
D.she can live longer with blood.
A.Take more core courses.
B.Register for optional courses.
C.Quit her present courses.
D.Try again a week later.

Not so for three-year-old Gabby Gingras, who has a rare disorder which means she can not tell when she is hurting herself.
As a baby, she did not cry when given a blood test.
While her teeth were growing, she bit her fingers until they bled and she hurt her tongue.
When a tooth was knocked out, she did not cry—all because she cannot feel physical pain.
Now, she was partly blinded by her habit of putting one finger in her eyes. Her eyes improved only after Mr. Gingras made her wear swimming goggles 24 hours a day. Doctors were confused by her condition so her parents set about finding out for themselves.
Mother Trish gave up her job and finally found the answer on the Net. Gabby had a disorder that could not be cured.
The family visited another sufferer—one of only 25 in the US—but admitted:" It's discouraging".
They discovered the 24-year-old girl of South Dakota was in a wheelchair after losing both legs to infections. As a girl, she was unaware when she was hurting her legs.
The three-year-old girl is suffering from a rare illness that ______.
A.she has never cried since she was a baby
B.she is made half blind by the strange illness
C.she often chews her own tongue
D.she is unable to feel pain physically
听力原文: I am writing to thank you for the interesting reports which appeared in the July '94 edition of Saturday Evening Post. I am interested in your reports since B12 deficiency is an inherited disorder in my family. In the late 1950s and early 1960s, a research project was carried out on it by London medical school.
My grandmother was 49 when she started vitamin t312 injections in 1949, She was admitted to the hospital with a blood disease. My mother was 63 when she began vitamin B12 injections. After reading your article, I believe her treatment was started too late. At the time, she almost lost her eyesight and was told that she had another diseases.
Earlier this year, I visited my doctor and explained that 1 felt very tired and asked for a blood test to establish whether I was suffering from B12 deficiency. I was told I was much too young and that only people in their 80s suffered B12 deficiency. I told him he was wrong and that research was carried out on my family 30 years ago.
I have always believed that prevention is better than cure. I now know why I love Kellogg's Honey Nut Cornflakes. They contain vitamins, including B12! If foods contain added vitamins, as
you suggest in your article, then B12 deficiency and diseases associated with it should be left to the past.

A.It is a thank-you letter to a medical doctor.
