W：Well, I'm not feeling
very well at the moment. I'm preparing for exams and
I've been staying up late at night studying. This morning
I got up very early to do some more work. and I fell
onto the floor. I came around after a few seconds.
M：Mm, Have you had
any other signs?
W：I've been pretty
nervous and my eyes hurt sometimes.
M：Well, it sounds as
if you've probably been overdoing your study and you're
too tired. I don't think there's anything to worry
about, but I think you should take it easy for a while
and try to get plenty of sleep.
M：I must read an announcement
that my flight has been delayed.
W：What's your flight
number?
M：Flight 226-for Philadelphia.
W：Oh, yes, the delay
is due to some difficulties in the machine.
M：Do you know how long
it will be?
W：Probably not more
than two hours.
M：Oh, dear, I'm afraid
I'll miss my connecting flight. I'm supposed to catch
an Eastern Airlines flight to Miami at 5:10. Is there
another flight available?
W：Just a minute. Let
me check…yes, there is a flight leaving for Philadelphia
in ten minutes, but it's full. I could put you on standby
if you wish.
M：Yes, all right. But
if I don't get on that flight, would it be possible
to change the connecting flight to Miami?
W：Let's see…there's
a United flight leaving Philadelphia at 7:45 this evening.
M：Could you get me
on that flight, please?
W：Yes, I'll check to see
if there's any space left.
W：Jack, have you and
Ann decided when you are going to get married?
M：Next year, we hope,
Mother. But we can't be sure about it. Finding a house
is the difficulty.
W：Have you made any
inquires yet?
M：Yes. It's almost
impossible to find a suitable house without furniture.
There are plenty of furnished flats, and furnished
houses, too, but the rents for these are very high.
I couldn't possibly afford them on my present income.
W：What would it cost
to buy a piece of land and build a house, do you have
any idea?
M：No, I haven't even
thought of it. That'll cost at least four thousand
pounds. It's no use our thinking about building a house.
W：And even if you had
a house, there'd be the furniture, and all sorts of
other things.
M：Yes, I know. Ann
and I have been saving up. We've saved a few hundred
pounds between us, and could buy furniture enough to
start with. But the house is the problem.
W：What size of house
would you want?
M：Oh, quite a small one.
A living-room and a kitchen. We'd like a dinning room,
of course, two bed-rooms and a bath-room.

18．What's the speaker's opinion about the noise pollution?
A．It has stopped in the countryside.
B．It has spread from cities to villages.
C．It has become the worst problem in the big cities.
Life gets noisier every day and very few people
can be free from noise of some sort or another. It
doesn't matter whether you live in the middle of a
modern city, or a faraway village. The chances are
that you'll be disturbed by jet airplanes, transistor
radios, oil-powered engines, etc. We seem to be getting
used to noise, too. Some people feel quite lonely without
background music while they're working.
Scientific tests have shown that total silence can
be a very frightening experience for human beings.
However, some people enjoy listening to pop music which
is very loud and can do harm to their ears. The noise
level in some music is far above the usual safety level
for heavy industrial areas.
One recent report about noise and concentration suggests
that although a lot of people say that any noise disturbs
their concentration. what really has an effect on their
ability to concentrate is a change in the level of noise.
It goes on to say that a background noise which doesn't
change too much may even help people to concentrate.
