Question

“Old wives’ tales” are beliefs passed from one generation to another. For example, most of us remember our parents’ telling us to eat more of certain foods or not to do certain things. Is there any truth in these teachings? Some of them agree with present medical thinking, but others have not passed the test of time.

Did your mother ever tell you to eat your carrots because they are good for your eyes? Scientists now report that eating carrots can help prevent a serious eye disease called macular degeneration. Eating just one carrot a day can reduce the possibility of getting this disease by 40%. Garlic(蒜) is good for you, too. It can kill the type of virus that causes colds.

Unfortunately, not all of Mom’s advice passed the test of medical studies. For example, generations of children have been told not to go swimming within an hour after eating. But research suggests that there is no danger in doing so. Do sweets cause tooth problems? Well, yes and no. Sticky sweets made with grains tend to cause more problems than sweets made with simple sugars.

Even though science can tell us that some of our traditional beliefs don’t hold water, there is still a lot of truth in the old wives’ tales. After all, much of this knowledge has been accumulated(积累) from thousands of years of experience in family health care. We should respect this body of knowledge even as we search for clear scientific support to prove it true or false.

【解析】

试题分析：我们大多数人都记得父母告诉我们要吃某些食物或者不要去做某些事情。这些告诫是对的吗？实际上，其中一些是与现在的医学思想相符合的，而另外一些却经不起考验。文章举了例子，并指出即便当我们寻找明确的科学证据来证明它的对错时，我们也应该尊重这类知识

1.推理判断题。第三段第一句是主题句。随后，举了饭后一小时内游泳和吃糖这两个例子来证明主题句。因此，这一段是通过举例来构成段落的。答案C
