You may know the saying: An apple a day keeps the doctor away. A recent study by the Chinese University of Hong Kong has discovered another saying: An apple a day keeps old age away.
The study involved fruit flies, as they share many genes (基因) with humans. Researchers gave food to two groups of fruit flies. Both groups got the same fruit, with one exception: The second group also got apples, while the first did not.
The results showed that flies that ate apples lived an average of 55 days longer than the flies that didn't eat apples. The study also found that apple - eating flies were more able to walk, climb and move about as they became old, *Journal of Agricultural and Food Chemistry* reports.
The researchers believe that the antioxidants found in apples are good for health.
In another experiment, researchers studied the diets of thousands of women. They found that those women who often ate apples were 20 per cent less likely to have a heart attack.
Scientists have recently discovered the apple's genetic code (遗传密码). This allows scientists to make new kinds of fruits that are healthier. Researchers are already using this information to grow apples with added antioxidants. Antioxidants help to keep eyes and joints (关节) healthy and protect against heart attacks and cancer.
Apples that help people lose weight may be in supermarkets in just four or five years. They are said to be "extra healthy" apples that can stop people from overeating.

答案：4. B 【点拨】根据“The study involved fruit flies, as they share many genes(基因) with humans.”可知,果蝇被用于研究的原因是它们与人类基因相似。故选 B。
5. A 【点拨】根据“Antioxidants help to keep eyes and joints(关节) healthy and protect against heart attacks and cancer.”可知,antioxidants 是帮助保持健康的物质。故选 A。
6. A 【点拨】根据“They found that those women who often ate apples were 20 per cent less likely to have a heart attack.”可知,通过对数千名女性的饮食进行研究,研究人员验证了苹果对健康的益处。故选 A。
7. C 【点拨】根据“Researchers are already using this information to grow apples with added antioxidants.”可推知,科学家正在研究新品种苹果。故选 C。

### 文章部分
你可能知道这句谚语：一天一苹果，医生远离我。香港中文大学最近的一项研究发现了另一句谚语：一天一苹果，衰老远离我。
这项研究以果蝇为对象，因为它们和人类有很多相同的基因。研究人员给两组果蝇喂食。两组果蝇得到的水果相同，但有一个例外：第二组果蝇还得到了苹果，而第一组没有。
结果显示，吃苹果的果蝇比不吃苹果的果蝇平均寿命长55天。《农业与食品化学杂志》报道，这项研究还发现，吃苹果的果蝇在变老时，行走、攀爬和活动的能力更强。
研究人员认为，苹果中含有的抗氧化剂对健康有益。
在另一项实验中，研究人员研究了数千名女性的饮食。他们发现，那些经常吃苹果的女性患心脏病的可能性降低了20%。
科学家最近发现了苹果的遗传密码。这使得科学家能够培育出更健康的新型水果。研究人员已经在利用这些信息种植含有更多抗氧化剂的苹果。抗氧化剂有助于保持眼睛和关节健康，并能预防心脏病和癌症。
有助于人们减肥的苹果可能在四五年内就会出现在超市里。据说这些是“超级健康”的苹果，能防止人们暴饮暴食。
