[00:00.87]Passage One
[00:02.84]The floor of the ocean contains many riches
[00:06.88]that can be used by human beings.
[00:09.62]Oil and some chemicals and minerals
[00:13.23]are already taken from the sea.
[00:15.86]By using nuclear energy, ocean water
[00:20.45]can be turned into fresh water by removing the salt.
[00:24.94]Producing food from farms under the sea
[00:29.20]is a possibility in the future.
[00:32.26]Food grown in the sea could help solve the problem
[00:36.64]of many of the world's people who go hungry every day.
[00:41.13]About ten to fifteen percent
[00:44.76]of the world's people do not have enough food.
[00:48.70]Some scientists believe
[00:51.65]that some day the sea will be used to make electric power.
[00:56.58]This would help meet the need for more power
[01:00.73]for world's industries.
[01:03.14]The decreasing supply of coal, oil and gasoline
[01:08.17]shows that the need to find new kinds of power is urgent.
[01:15.72]Questions 1 to 3 are based on the passage you have just heard.
[01:21.19]1. According to the talk, what does the sea contain?
[01:43.52]2. What can be used to remove salt
[01:49.76]from ocean water to get fresh water?
[02:08.25]3. Why is the need to find new kind of power urgent?
[02:32.30]Passage Two
[02:35.59]I persuaded my uncle to let me have a bicycle
[02:39.52]at the beginning of the summer holidays.
[02:42.05]My aunt was against it,
[02:44.58]saying I would only break my neck,
[02:47.31]but she at last gave in.
[02:49.83]I ordered it before school ended,
[02:52.89]and a few days later
[02:54.42]I was the owner of a beautiful new bicycle.
[02:57.70]I decided to learn to ride it by myself,
[03:01.42]and my classmates had told me that
[03:04.04]they had learned in about half an hour.
[03:06.78]I tried and tried, and at last came to the conclusion
[03:11.16]that I was unusually stupid,
[03:13.62]but even after my pride was hurt enough
[03:17.24]for me to allow the gardener to hold me up,
[03:20.30]I seemed at the end of the first morning
[03:23.08]no nearer to being able to get on by myself
[03:26.91]than at the beginning.
[03:28.57]Questions 4 to 6 are based on the passage you have just heard.
[03:34.61]4. What is the story mainly about?
[03:56.39]5. Why wouldn't the boy's aunt have him riding a bicycle?
[04:17.58]6. Which of the following statements is true?
[04:39.93]Passage Three
[04:41.90]Memory, they say, is a matter of practice and exercise.
[04:47.27]If you have the wish and really make a conscious effort,
[04:51.75]then you can quite easily
[04:53.66]improve your ability to remember things.
[04:56.93]But even if you are successful,
[05:00.12]there are times when your memory seems to play tricks on you.
[05:04.82]Sometimes you remember things that really did not happen.
[05:09.86]One morning last week, for example,
[05:13.90]I got up and found
[05:15.77]that I had left the front door unlocked all night,
[05:19.05]yet I clearly remember locking it carefully the night before.
[05:23.32]Memory ¡°tricks¡± work the other way as well.
[05:28.56]Once in a while you remember not doing something
[05:32.83]and then find out that you did.
[05:35.46]One day last month, for example,
[05:38.74]I was sitting in a barber shop
[05:40.92]waiting for my turn to get a haircut,
[05:43.66]and suddenly I realized that I got a haircut two days before
[05:49.14]at the barber shop across the street from my office.
[05:52.74]We always seem to find something funny and amusing in incidents
[05:59.64]caused by people's forgetfulness or absent mindedness.
[06:03.69]Stories about absent-minded professors have been told for years,
[06:09.92]and we never get tired of hearing new ones.
[06:13.54]Unfortunately, however, absentª²mindedness is not always funny.
[06:20.21]There are times when ¡°tricks¡±of our memory
[06:23.49]can cause us great trouble.
[06:26.99]Questions 7 to 10 are based on the passage you have just heard.
[06:34.53]7. What should we do if we want to have a good memory
[06:40.32]according to the passage?
[06:57.66]8. Which of the following statements is true
[07:03.68]according to the passage?
[07:21.54]9. What can we infer from the passage?
[07:42.31]10. What can be learned from the passage?
