Passage Two

Most Americans don't eat enough fruits, vegetables or whole grains.

Research now says adding fiber to the teen diet may help lower the risk of breast cancer.

Conversations about the benefits of fiber are probably more common in nursing homes than high schools.

But along comes a new study that could change that.

Kristi King, a diet specialist at Texas Children's Hospital, finds it hard to get teenage patients' attention about healthy eating.

By telling them they are eating lots of high-fiber foods could reduce the risk of breast cancer before middle age.

That's a powerful message.

The new finding is based on a study of 44,000 women.

They were surveyed about their diets during high school and their eating habits were tracked for two decades.

It turns out that those who consumed the highest levels of fiber during adolescents had a lower risk of developing breast cancer, compared to women who ate the least fiber.

This important study demonstrates that the more fiber you eat during your high school years, the lower your risk is in developing breast cancer in later life.

The finding points to long-standing evidence that fiber may reduce circulating female hormone levels, which could explain the reduced risk.

The bottom line here is the more fiber you eat, perhaps, a lower level of hormone in your body, and therefore, a lower lifetime risk of developing breast cancer.

High-fiber diets are also linked to a reduced risk of heart disease and diabetes.

That's why women are told to eat 25 grams of fiber a day—man even more.

Questions 13 to 15 are based on the passage you have just heard.

Question 13: What does the new study tell about adding fiber to the teen diet?

Question 14: What do we learn about the survey of the 44,000 women?

Question 15: What explanation does the speaker offer for the research finding?

短文二

绝大多数美国人都没有食用足够多的水果、蔬菜或全谷物。

研究者现在宣称，在青少年饮食中添加纤维有助于降低患乳腺癌的风险。

有关纤维益处的交谈，养老院可能要比高中学校更普遍。

但一项新研究的出现可能会改变这一状况。

田纳西儿童医院的饮食专家克里斯蒂·金发现，要引起青少年患者对健康饮食的注意很难。

但通过告诉他们食用大量高纤维的食物能降低中年之前患乳腺癌的风险。

会是一个强有力的信息。

这个新发现是基于一项涉及44,000名妇女的研究。

该研究调查了她们高中时期的日常饮食，并跟踪她们的饮食习惯长达二十年。

研究结果显示，相对于那些青少年时期消耗最少纤维的妇女，那些在该时期消耗了最高水平纤维的人患乳腺癌的风险要更低。

这项重要的研究表明，你在高中阶段食用的纤维越多，日后患乳腺癌的风险就越低。

该研究证实了长期存在的证据，那就是纤维能够降低雌性激素的循环水平，它能够解释该风险降低的原因。

在这里最重要的一点是你食用的纤维越多，那么你身体里的荷尔蒙水平可能就越低，因此一生当中患乳腺癌的风险就越低。

高纤维的饮食还可以降低心脏病和糖尿病的患病风险。

这就是为什么女性被告知一天要食用25克的纤维——男性甚至要食用更多。

问题13到15是基于你刚才所听到的那篇短文。

问题13：有关在青少年饮食中添加纤维一事，这项新研究表明了什么信息？

问题14：有关44,000名女性的调查，我们能从中得到什么信息？

问题15：说话者给这项研究发现作出了什么样的解释？
