W: There are about a thousand protein receptors in the nose that tell the brain what it's smelling. Each receptor can detect one or more odors but scientists have never before linked a specific odor molecule to a particular receptor. Writing in the journal Science, researchers at New York's Columbia University report doing just that with a meat odor and a receptor in the noses of rats. Steward Fairstine led the team of investigators. He says humans arc capable of discerning something like ten thousand different odors. Mrs. Fairstine says the research might also tell scientists more about brain chemicals and hormones which are part of the same family as odor receptors. Jessica Bermon, VOA news, Washington.

Red Meat Links to Higher Risk of Breast Cancer

Exercise and keeping a healthy weight are two things that doctors say might help women lower their risk of breast cancer.

Mothers may reduce their risk if they breastfeed for at least four months. For older women, hormone replacement therapy can lower the risk of some other diseases. But it has been found to increase the risk of breast cancer. So women should consider their choices carefully. The same may be said for diet.

New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive. The growth is fed by the levels of estrogen or another hormone, progesterone, in the body.

Researchers at Brigham Women's Hospital in Boston, Massachusetts, reported the findings as part of a health study of nurses. The researchers followed the health of more than 90,000 women from 1991 to 2003. Those who ate the most red meat ate more than one and one-half servings a day. A serving was defined as roughly 84 grams. Those who ate the least red meat ate less than three servings a week. This is what the study found about breast cancers that were hormone receptor-positive: The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.

Eunyoung Cho, the lead author of the report, says more research is needed to know the reason for the link. But in the past, researchers have suggested that three things may play a part. One is the way meat is cooked or processed. Another is the use of growth hormones in cows. And the third is the kind of iron in red meat. The study appears in the Archives of Internal Medicine.

And now we have more to tell you about our subject -- resveratrol. We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer. The mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.

Now, scientists in France say resveratrol also improves muscle performance -- again, at least in mice. They were able to run two times as far in laboratory treadmill tests4 as mice normally could. The study at the Institute of Genetics and Molecular and Cellular Biologys appeared in the journal Cell.

听力原文： Today I'd like to continue to talk about the reason why the United States developed at such a high speed in the past 400 years. There are many factors. America has an abundance of natural resources including some of the best farm lands in the world. People from many countries settled them, bringing with them a wealth of knowledge and skills. But in the last 100 years it has been the workingman that was the backbone of the nation.

What is the American workingman？ He's a worker in a shoe factory or a meat packing-house or a coal mine. But more than that, he is a husband and a father. He raised his children to value the importance of cooperation. And he raised his children to help them better themselves. Seldom do their children forget the value they have learnt at home.

The workingman fought hard to achieve what he has for almost all his life, but today the workingman is faced with a new kind of struggle. Ever advancing technology is taking his job. It's very probable that the workingman will be replaced by a machine.

(23)

A．The United States is quite rich in natural resources.

B．The Americans are the people with knowledge and skills from many countries.

C．The young Americans are well-educated to value the importance of cooperation.

D．The workingman is now enjoying the wonderful life he achieved through struggle.

_1_ about it afterward. We say we want only the best, but we strangely enjoy junk food. We're _2_ with health and weight loss but face an unprecedented epidemic of obesity（肥胖）. Perhaps the _3_ to this ambivalence（矛盾情结）lies in our history. The first Europeans came to this continent searching for new spices but went in vain. The first cash crop（经济作物）wasn't eaten but smoked. Then there was Prohibition, intended to prohibit drinking but actually encouraging more _4_ ways of doing it.

The immigrant experience, too, has been one of inharmony. Do as Romans do means eating what “real Americans” eat, but our nation's food has come to be _5_ by imports—pizza, say, or hot dogs. And some of the country's most treasured cooking comes from people who arrived here in shackles.

Perhaps it should come as no surprise then that food has been a medium for the nation's defining struggles, whether at the Boston Tea Party or the sitins at southern lunch counters. It is integral to our concepts of health and even morality whether one refrains from alcohol for religious reasons or evades meat for political.

But strong opinions have not brought _7_ . Americans are ambivalent about what they put in their mouths. We have become _8_ of our foods, especially as we learn more about what they contain.

The _9_ in food is still prosperous in the American consciousness. It's no coincidence, then, that the first Thanksgiving holds the American imagination in such bondage（束缚）. It's what we eat—and how we _10_ it with friends, family, and strangers—that help define America as a community today.

听力原文： A British study of how diet affects the health of new mothers and their babies produced the surprise finding that vegetarian women are more likely to have girls, one of the report's authors said yesterday.

In what is thought to be the first study of its kind, researchers at Nottingham University in central England found significant differences in the sex of babies born to vegetarian and meat and fish-eating women. They were examining the health conditions in vegetarian and non-vegetarian mothers, looking at things like hemoglobin levels, which show how much iron the mother has in her blood, and birth weights.

Altogether 5,942 pregnant women were involved in the study when they were booked in Nottingham's City Hospital during 2001. According to the researchers, vegetarian mothers were defined as pregnant women who avoided meat and fish. Nearly five percent were vegetarian among them, a total of more than 250 women.

The birth ratio in Britain is that for every 106 boys born there are 100 girls, that's pretty constant. In their sample group of vegetarians there were 81.5 boys born for every 100 girls.

To further test their surprise findings, they increased the sample number to what scientists called a "statistically significant" level. The study was extended for a further six months so that the sex of more babies could be looked at. The results, covering around 150 more vegetarian women, were" just about exactly the same".

The study also found that vegetarian mothers were less likely to smoke during pregnancy -- 10 percent did so, compared with 20 percent of meat-eaters.
