Question

【題目】A recent study has shown that eating a small amount of dark chocolate every day could be good for your health. Scientists have found that a regular 2 ounces can help lower blood pressure and reduce the risk of having a heart attack or stroke（中風(fēng)）without any weight gain. But take care before you reach for a large bar. The effects are canceled out if more than 30 calories are taken into your body each day, the researchers warn.

It’s already known that a chemical called polyphenol（多酚）, found in chocolate, can help reduce blood pressure, and blood pressure lowered in this way can reduce the risk of death from a stroke by 8 percent and from a heart attack by 5 percent, scientists declare. And it can also reduce the risk or death in general by 4 percent.

A daily diet with a little chocolate has the same effect with some special diets designed to lower blood pressure, according to one researcher. “Although all the degree of the blood pressure reduction is small, the effects are quite obvious,” the researchers said.

However, Sara Stanner, a nutritionist at the British Heart Foundation, is quite cautious. “This study suggests that small quantities of small chocolate might have good effects on blood pressure. However, it is important to remember that chocolate is also high in fat and calories. So eating much is not good for your heart.” “Polyphenols are also found in fruits and vegetables, which can be taken in without the risks associated with overintake,” she added.

But the German study shows that the fat content does not cancel out the good effects—at least where small amounts are concerned.

試題分析：文章列舉了吃巧克力的好處和壞處的不同觀點及具體細節(jié)。

【1】B推理判斷題。根據(jù)第二段中的reduce the risk of death from a stroke by 8 percent and from a heart attack by 5 percent, scientists declare. And it can also reduce the risk or death in general by 4 percent.可知本段主要用了列舉數(shù)字說明，故選B.

【2】 B推理判斷題。根據(jù)第一段Scientists have found that a regular 2 ounces can help lower blood pressure and reduce the risk of having a heart attack or stroke（中風(fēng)）without any weight gain.可知適量的巧克力能降血壓、減少心臟病和中風(fēng)、不增重，A項錯在heavily，C項巧克力不是用來減肥的，故選B.

【3】D細節(jié)推理題。根據(jù)倒數(shù)第二段So eating much is not good for your heart.” “Polyphenols are also found in fruits and vegetables, which can be taken in without the risks associated with overintake,”可知Sara Stanner不建議多吃巧克力，建議多吃蔬菜水果，故選D.

【4】A推理判斷題。文章最后提到德國的發(fā)現(xiàn)，下面會具體說明發(fā)現(xiàn)的具體細節(jié)，故選A.
