●What prevents depression; tea,coffee or hot chocolate? Women who drink for or more cups of coffee a day are a fifth less likely to become depressed. Drinking two or three cups reduces the risk by 15 percent.This is the result of a study of 51,000 women over ten years,published in the Journal of the American Medicine Association. One theory is that caffeine reduces theeffect of the chemical adenosine (腺苷) in the brain,which can make us feel sleepy by slowing down nerve cell activity.Some anti-depressants also work by blocking the adenosine receptors.Coffee was found to be far more influential on depression levels than hot chocolate or tea due to the high caffeine content. ●How many eggs can we healthily eat:one a day or two a day? Neither-eat them freely.We've long been warned to stick to two or three eggs a week because of their high cholesterol (胆固醇) content.But according to the Food Standards Agency,there is no recommended limit to how many eggs we can healthily eat,unless you have been told to cut down by your doctor. There is no evidence that eating eggs raisescholesterol levels,and researchers found that eggs contain less cholesterol than in the past because hens are no longer given bone meal,which was banned in the 1990s after the BSE (疯牛病) crisis. Research by the British Egg Council found that a medium egg gives you around 100 mg of cholesterol,a third of the 300mg recommended daily limit.

A.Tea. B.Chocolate. C.Adenosine. D.Coffee.

2.We can infer from the text that __ .

A.too much caffeine will probably make people sleepy B.coffee contains less caffeine than tea or hot chocolate C.one is depressed if his brain chemical adenosine is active D.tea and hot chocolate have no effect on men's depression

3.What can we learn about eggs from the text?

A.We should stick to two or three eggs a week in general. B.Eat as many eggs as you like unless your doctor advises you not to. C.Eggs contain more cholesterol at present than ever before. D.One egg daily and you'll get more cholesterol than recommended.
