[00:04.97]Part Two

[00:07.24]Listening-Centered Activities

[00:10.66]Listening I

[00:13.90]Exercise 1

[00:17.53]Directions:

[00:20.27]Listen to the passage and answer the following Yes/Not questions.

[00:27.40]The possibility that something bad will happen is a rise

[00:32.33]Risk also can be defined 1 as the degree of danger that goes along with an opportunite

[00:40.57]All risks have possible negative resulte

[00:45.36]However, some risks are worth taking

[00:50.94]For example, suppose that you have the chance to join a school team

[00:57.67]You risk a possible injury while playing

[01:02.42]to achieve the sense of accomplishment 2 that comes with being on the team

[01:09.01]You may decide that the pleasure of playing is worth the risk of injure

[01:15.31]By being in good health, you can also reduce the risk of physical injury.

[01:22.15]How can we determine the risks involved in an action

[01:27.95]Many risks that relate to health choices have been studied

[01:33.85]Scientists use statistics 3 to measure these risk

[01:39.22]Statistics is a branch of mathematics

[01:43.93]that helps determine the possibility that something will occue

[01:49.91]The information about the possibility is called statistical 4 risk

[01:56.93]and can help you make healthy choices.

[02:02.15]For example, statistics indicate that in the United States

[02:09.49]the chance of dying from cancer is about 20 percent.

[02:15.76]In other words, two out of every ten deaths are due to some kind of cancer

[02:24.11]Therefore, the risk of death from cancer is quite high

[02:30.77]However, statistics also show

[02:36.89]that 80 percent of all cancers are related to things over whichyou have some control

[02:45.24]In other words, you can make choices that will reduce your risk of developing cancel

[02:53.63]These include such things as avoiding pollution

[02:59.24]not smoking, and eating a diet high in fiber 5

[03:05.62]If you do these things, you are less likely to develop cancer.

[03:12.64]1 Is the passage mainly about risks from nature

[03:20.70]2 Do all risks have possible negative results

[03:28.58]3 Are all risks worth taking

[03:34.92]4 Is it possible to measure some risks

[03:41.83]5 Are most cancers related to one's unhealthy choices

[03:50.62]Exercise 2

[03:54.58]Directions:

[03:58.18]Listen to the passage again and answer the following questions

[04:04.19]by completing the sentences given.

[04:09.34]1)What is a risk?

[04:13.69]2)How can health risks be measured?

[04:19.96]3)What is statistical risk?

[04:25.82]4)What are the healthy choices mentioned in the passage?

[04:32.30]Listening II

[04:36.08]Exercise 1

[04:39.36]Directions:

[04:43.36]Listen to the conversation between a husband and a wife

[04:48.54]Decide whether the following words or phrases are mentioned in the conversation

[04:55.96]as factors which might influence one's life span 6

[05:02.69]Put a tick beside the word or phrase if it is mentioned

[05:08.48]Then decide which two are the highest risk factors.

[05:15.97]H: Oh! It's unbelievable!

[05:20.80]W: What's the matter?

[05:24.36]H: This article says that life spans 7 vary according to race

[05:31.38]income level and whether you are male or female

[05:37.18]Er now, can you guess which is the most important factor?

[05:43.84]W: Mm, I think it might be your sex.

[05:49.49]H: That's right

[05:52.66]You see, my grandma lived four years longer than my grandpa

[05:59.50]Generally speaking, women live longer than me

[06:05.33]In 1993, the average life span of women was 6.9 years longer

[06:14.36]than that of men in the United States.

[06:19.40]W: 6.9 years? I can't believe it Then how about race?

[06:27.54]H: Race... The paper says white women live 5.1 years longer than black women.

[06:39.71]W: So this means I am doubly luckly since I am a white woman.

[06:45.76]H; Yes. But actually the largest risk you could run--after being born male--

[06:53.89]is being poor

[06:57.67]Being poor is far more likely to kill you than smoking

[07:03.32]drinking, a hereditary disease, or an unhealthy lifestyle
