Dinner parties are out of date. Alumni (毕业生,校友) album are old-fashioned. School leaving is taking on a new turn：it is going online! Graduating students at Qinghua University are saving all their joys and sorrows from university on a CD. Some are setting up their alumni records online, such as Chinaren.com and 5406.net. With computer usage and Internet access becoming even more popular, students are throwing away the traditional graduation book. Instead they are using alumni books online, in CDs or disks, electrolyzing(电解) their graduation in the e-age.
"It is much easier and safer to save." Xu Ziguo, a civil-engineer-major at Qinghua University said. Like his class, most of Qinghua's to-be graduates are using the CD alumni records and online association. Xu said CD records can save more than the actual books. Photos and videos on school activities and normal campus life, and messages may be all included in the thin plastic with the help of a CD-Writer. "Everything is so lively when I watch it, just like what is happening on campus," Xu said. Another student at the Renmin University of China, Lu Yangzhen said her class saved all the memorable messages on a disk. They use a common chat room online to communicate after graduation. Many classes will keep their homepages on campus for future communication, Lu said.
Dotcom companies are also seizing the opportunity to get more clicks. Chinaren.com said it provided improved services for the users. One service is to send group emails, meaning if a user sends an email to one address, all his or her classmates can get it at the same time. But what if the Dotcom company breaks down one day? Xu said they had left a "backup". That is to use the old way with a person working as the liaison.

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged. www.zxxk.com
Gene technology can help people to give birth to healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government must take care to control gene technology.
1.What does “these two killers” in the second paragraph refer to?

The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.
JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers."
For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident.
Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water.
JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables."
The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean.
JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."
Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.
Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.
A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths.
The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen.
