A newly published AIDS study could open another front in the battle against HIV infection by showing that gene therapy can be used to stop infected cells from spreading the deadly virus, researchers said.
In a test-tube experiment believed to be the first of its kind, researchers based at Children’s Hospital of Philadelphia were able to block the operation of the" tat "gene that allows HIV to spread throughout the body from infected cells.
Up to now, genetic AIDS research has concentrated on finding ways to help healthy cells withstand the ravages of the HIV virus that infects an estimated 16, 000 new victims a day, mainly in the developing world.
But by working with human cells already infected with HIV, the team was able to reduce the tat gene’s virus-replicating functions by 80 percent to 90 percent, according to findings published in the journal Gene Therapy.
That, researchers said, raises the possibility of a new gene the
A. AIDS study raises hopes for gene therapy treatment.
B. A new killer of HIV virus.

[不定项选择题]First there were hammers banging.Then paint brushes.Then carpet.Soon we had a new room above the garage.And my grandmother moved in. It was the late 1960s, I was 10 and had no idea that we were going against the grain, that the trend was for families to splinter, seniors to take better and longer care of themselves, kids to move away younger and younger. All I knew was that our family had three generations under one roof, which made a difference in who sat where in the car, what desserts mysteriously disappeared overnight and how long you waited outside the bathroom door. This past week, a new census report raised a lot of eyebrows.In the past decade, there has been a resuming of the family deck: a 30 percent rise in U.S.households with at least three generations, People are moving back in.Generations are consolidating So I guess we were ahead of our time.Forget about a babysitter.Of course, today this has more to do with money than anything else.Senior citizens have a harder time paying their bills and their children have a harder time shelling out monthly checks for retirement or nursing homes.Kids can’t find jobs, even college grads.What it means, ultimately, is more people under one roof, with a broader span of years between them.Braces and dentures.Grey hair and dyed hair.This is lamented as a regrettable consequence of a feeble economy.But I’m not sure it’s a bad thing. I learned a lot from having our grandmother in the house.For one thing, it beat hiring a babysitter we didn’t like.And there was someone else to take us to school or drive us to places when our folks were working.There was another family member at the school plays and another person to cry to if we were hurting.I got to watch how my mother related to her mother, and I saw that mine wasn’t the only generation that found the one before it confounding and, at times, infuriating. I also heard more family history than I did with just one older generation under the roof.There was no shortage of conversation.Dinners were louder and animated.In short, we were bigger.My grandmother spoke about grant’s neighborhood, sitting on fire escapes and drinking egg creams, and talked about listening to the radio during the Pearl Harbor attacks.They talked about relatives I’d never met and never would meet, my bloodline.(缺失部分内容) It wasn’t all “The Waltons”.I knew who I was and where I came from more once my grandmother called our home her home. There’s a wonderful film called “Avalon” that follows an immigrant’s family in the 20th century.At the beginning of the film, it is Thanksgiving, and a small city home is Jammed with uncles, aunts, grandparents, kids.At the end of the film, years later, it is Thanksgiving again, and a family of four sits in a suburban kitchen eating with the TV on.Yes, it was cramped, sometimes annoying, and it was no fun waiting for a shower or hearing my grandmother snoring.But years later, when she finally moved out, I can tell you this.It got quieter.It was less funny.We were still a family, but we were … smaller. So the economy may be driving us more under one roof, and we may whine that our independence is withering.But for centuries, kids, parents, grandparents and even great-grandparents have been sharing space, and when it stopped, we began complaining about the collapse of family values.Maybe the economy, of all things, is offering us a small fix. What does the writer value most in a three-generation family?
A.A better sense of himself and a closer tie to his family.
B.Richer knowledge about his relatives and neighborhoods.
C.Parental love and support whenever and wherever he needs.
D.Family conversations at the dinner table about interesting issues.

to get from Kathmandu to the tiny village in Nepal, Dave Irvine-Halliday spent more than two days. When he arrived, he found villagers working and reading around battery-powered lamps equipped with light-emitting diodes, or LEDs--the same lamps he had left there in 2000.
Irvine-Halliday, an American photonics engineer, was not surprised. He chose to use LED bulbs because they are rugged, portable, long-lived, and extremely efficient. Each of his lamps produces a useful amount of illumination from just one watt of power. Villagers use them about four hours each night, then top off the battery by pedaling a generator for half an hour. The cool, steady beam is a huge improvement over lamps still common in developing Countries. In fact, LEDs have big advantages over familiar incandescent (白炽的)lights as well--so much so that Irvine-Halliday expects LEDs wil
