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.

A. a way for treating AIDS

A.can kill all the HIV viruses

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).

1.In the second sentence of the passage, “laid out” means ______.

A.built             B.be put            C.designed          D.cut down

2.The streets running from north to south are called _______.

A.avenues in London                      B.streets in America

C.avenues in New York                     D.streets in London

3.According to the writer’s opinion, ______.

A.avenues and streets are the same

B.streets in America are better than avenues in England

C.streets in New York are better than those in London

D.the writer didn’t agree with the London streets planners

4.The names of streets both in London and New York ______.

A.are quite good                         B.are interesting

C.are not practical                        D.differ greatly in form

“Can I see my baby?” asked the happy new mother. The bundle(婴儿包)was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she gasped-the baby has been born without ears. Time, however, proved that the baby’s hearing was perfect except his appearance.

One day when he rushed home from school and threw himself into his mother’s arms, he cried out bitterly, “A boy, a big boy… called me a f-…freak.” She sighed, knowing that his life was to be endless of heartbreaks.

He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president, but for that. He developed a gift for literature and music.

The boy’s father had a talk with the family doctor. Could nothing be done? “I believe we could graft(移植)on a pair of outer ears, if they could be donated(捐献),”the doctor decided. So the search began for a person who would make such a sacrifice a young man. Two years went by. Then, “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret,” said the father.

The operation was a brilliant success. His talents blossomed (开花)into genius. School and college became a series of successes. Later he married and entered the diplomatic(外交)service. “But I must know!” he urged his father. “Who gave so much for me? I could never do enough for him.”

“I do not believer you could,” said the father, “but the agreement was that you are not to know….not yet.” The years kept the secret, but the day did come…. one of the darkest days that ever pass through a son. He stood with his father over his mother’s casket(棺材).Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish-brown hair to let out the secret.
