a part of the ritual of the office worker and businessman.

On weekdays in pubs and bars throughout America, there is the late afternoon happy hour. The time may vary from place to place, but usually it is held from four to seven. After the workday is finished, office workers in large cities and small towns take a relaxing pause and do not go directly home. They head off instead for the nearest bar or pub to be with friends, co- workers and colleagues. Within minutes the pub is filled to capacity with businessmen and secretaries, office clerks and stock executives. They gather around the bar like birds around a fountain or forest animals around a watering hole and chat about the trifles of office life or matters more personal. This is their desert garden, the place to relieve the day's stress at the office.

At these happy hours, social binding occurs between people who share the same workplace or similar professions. They may chat about each other or talk about a planned project that has yet to meet a deadline. In this sense, these places become extensions of the workplace and constitute a good portion of one's social life.

For office workers and businessmen, the happy hour is their ______.

A．professional requirement

B．regular practice

C．refreshing break

D．unpaid work

Volunteers are being recruited(征募) to eat raw potatoes in the first human trials of a vaccine grown in genetically engineered vegetables. Researchers in Texas hope that people who eat the potatoes will be protected against common gut(肠，肠子) infections. They believe this technique could prove to be a cost-effective way of growing vaccines in developing countries where such diseases are still killers.

Other researchers previously succeeded in using similar techniques to produce potential vaccines Now Hugh Mason and his colleagues at Texas A & M University(得克萨斯农业及机械大学) their plant vaccines on mice and plan to recruit 15 volunteers for a human trial.

The team first tested the technique in tobacco plants. They took a strain of Escherichia coli(大肠杆菌) bacteria that causes food poisoning, and identified the part of the poison which binds to its victims gut cells. They then used a modified plant bacterium called Agrobacterium tumefasciens to transfer the segment of DNA which manufactures the binding protein into the tobacco plant. Under normal circumstances, these bacteria transfer packets of DNA into plant cells to force the plant to manufacture the nutrients they need.But in the modified bacteria, the DNA package includes the gene to pro- duce the binding protein.

Once the foreign DNA segment was incorporated(结合，合并) into the tobacco's own DNA, the bacteria were killed off with antibiotics. Mason's team then grew these modified tobacco plants and found that they produced the E. coli binding protein.

Proof of success came when the tobacco leaves were mashed up(捣碎) and squirted into the stomachs of mice. Mason says that within days the mice started producing specific antibodies to the E. coli poison, but suffered no ill effects from digesting the binding protein. Mason then produced genetically engineered potatoes and fed these to mice, with similar results.

Mason's team have used plants to produce vaccines against a number of other infectious agents. For example, they have made a vaccine using a protein from the shell of the Norwalk virus, which causes diarrhoea(腹泻) in children.

A third vaccine has also been produced in tobacco using a surface protein from the hepatitis B virus. But Mason says that so far they have only been able to produce small amounts of it in potatoes. Although a vaccine already exists against hepatitis B, a cheaper plant version could make mass immunisation(群众性免疫) possible.

One problem with growing potatoes to produce vaccines is that cooking tends to destroy the protein component of the vaccine, so they must be eaten raw. Mason thinks that bananas may be a better option. "One banana could potentially produce a whole host of different vaccines," says Mason.

The purpose of this text is______。

A．to prove that doctors don't like vegetables

B．to amuse the reader by telling some funny things

C．to describe how vegetables can grow vaccines for their own use

D．to tell the reader about a cheaper way of growing vaccines

from the same motives, and cover the same human needs. Therefore, like most popular notions this also【M1】______ rests not on actual facts, but on superstition. It is utterly false that love results from marriage. On rare occasions one does hear a【M2】______ miraculous case of a married couple falling in love after marriage, but on close examination it will be found that it is a merely adjustment to【M3】______ the inevitable. Certainly the growing—used to each other is far away from the spontaneity, the intensity, and beauty of love, without which the intimacy of marriage must prove degrading to both the woman and the man. Marriage is primarily an economical arrangement, an【M4】______ insurance pact. It differs from the ordinary life insurance agreement only in that it is more binding, more exacting. Its returns are significantly small compared with the investments. In taking out an【M5】______ insurance policy one pays for it with dollars and cents, always【M6】______ in liberty to discontinue payments. If, however, womans premium is【M7】______ a husband, she pays for it with her name, her privacy, her self-respect, her very life, "until death doth part". Moreover, the marriage insurance condemns her to life-long independency, to parasitism, to【M8】______ complete uselessness, individually as long as socially. Man, too, pays【M9】______ his toll, but as his sphere is wider, marriage does not limit him as much as to woman. He feels his chains more in an economic sense.【M10】______

【M1】

听力原文： Cornton Vale is a new prison specially designed for women in Scotland. The 226 prisoners there live in small units of seven rooms. There is a kitchen where they cook their own meals and a lounge with fitted carped and armchairs.

The "wake-up, wake-up" called by loudspeaker at 7 every morning is followed by a music program, which creates the atmosphere of a holiday camp. During the day, most of the prisoners are employed in three workshops, making toys or clothing. Their earning—up to 90 pence a week—can be spent in the prison shop.

The gymnasium, which also acts as a cinema and concert hall, has facilities for table tennis, basketball and dancing.

Prisoners, particularly those with long sentences, are encouraged to be independent and take responsibility for themselves and others. This is in many ways much more demanding than simply serving time. Just as the deputy governor of this prison once said, "We try to preserve the prisoners's self-respect as much as possible, by imagining ourselves in their position" ourselves in their position.' His words explain why this new prison is mn in a unique way.

A．A small town in Britain.

B．A new type of jail.

C．A labor camp.

D．A big gymnasium in Scotland.
