Lesson A Health Myths or Facts?

Listening

SCRIPT

Track 7-1

1: A lot of people think going outside with wet hair will make you sick. But, in fact, illnesses like a cold or the flu are caused by a virus, not going outside with a wet head.

2: “An apple a day keeps the doctor away,”says the saying, and yes, apples are high in vitamins and they’re low in fat. But there are over four teaspoons of sugar in every apple, so eating too many can be bad for your teeth. Eating different types of fruit and vegetables every day is what really keeps the doctor away.

3: Eating food cooked in oil isn’t bad for your skin—unless you eat too much of it. In fact, the right type of oil is good for your health. For example, research shows that olive oil may prevent dangerous diseases like cancer, including skin cancer.

4: Many of us spend a lot of time looking at computer, phone, and TV screens every day. For most people, looking at these devices doesn’t make their eyesight worse, but it can cause headaches. To avoid this problem, research shows it’s good to look away from the screen every few minutes.

1. An apple a day keeps the doctor away：最早出现在英国威尔士的谚语，也可说Eat an

apple on going to bed, and you’ll keep the doctor from earning his bread。

2. olive oil：橄榄油，在地中海沿岸国家有几千年的历史，在西方被誉为“液体黄金”、

“植物油皇后”。

3. make one’s eyesight worse：使视力变差

Conversation

Track 7-2

A: Hey, are you okay?

B: No, I think I’m getting sick. I have a sore throat.

A: You ought to go home and rest.

B: Yeah, I think I will.

A: And try drinking hot tea with honey.

B: Will that really help?

A: It always works for me, and in fact, research shows that honey can relieve a sore throat.

1.relieve a sore throat：缓解咽喉痛（蜂蜜有抗菌消炎、散痛止痒等功效）

Lesson B Forever Young – and Healthy

Listening 1

SCRIPT

Track 7-3

How long can humans live? In most developed countries, people are now living an average of 75 years. But scientists are trying to find ways to lengthen our lives—perhaps to 120 years or older—and to help us remain young as we age.

To do this, scientists are studying special groups of people around the world. These people seem to be immune to certain diseases that shorten our lives. Some Ecuadorians, for example, have a gene that seems to prevent dangerous diseases like cancer and diabetes. Japanese American men also seem to have a special gene that lowers their chance of getting cancer and heart disease. Learning how these genes work could help extend life for us all and keep us healthier, too.

1. lengthen our lives —perhaps to 120 years or older：科学家普遍认为人类的“天年”是120

岁，但某个衰竭的器官会成为“木桶上最短的那块木板”。

2. as we age：当我们岁数变大的时候

3. be immune to certain diseases：对某些疾病免疫

4. gene：生物体的生、长、衰、病、老、死等一切生命现象都与基因（遗传因子）有关。

5. diabetes：糖尿病

6. extend life：延长寿命

Track 7-4

F: Listen to this: “Living to one hundred twenty or older seems like it’ll be possible in the future.

A recent study done in the U.S. says that by 2050 almost half a million people in the U.S

alone will be over one hundred years old.”

M: Wow, almost half a million? That’s amazing.

F: Yes, it’s impressive, but do you really think living to one hundred twenty is a good idea?

M: Why not? We’ll have more time in our lives to do things. How can that be bad?

F: Well, I just don’t know … Livi ng longer doesn’t necessarily mean living better, does it?

You’ll live most of your life as an older person. And many older people have health problems.

M: Yes, but scientists are working all the time to cure diseases like cancer and to slow the aging process, so we’ll be healthier and we’ll age better.

F: I know what you mean, but I think that living to one hundred twenty isn’t good for our planet.

We already have over seven billion people on Earth. If more people are going to live longer, will we have enough natural resources?

M: That’s a good point, but I still think living to one hundred twenty sounds good to me.
