Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea.   小題4:

Ten years ago, I used to be very fit. __小題1:__ I used to play tennis a lot and go for long walks. In those days, I didn’t earn very much. I had a job in an office. It wasn’t a very good job but I had a lot of time to do the things I enjoyed doing.
__小題2:__ The pay was better, but the hours were a lot longer. I bought a car and drove to work every day. I began to take people out to lunch. And I began to put on weight, too. I stopped playing tennis and going for long walks at weekends because I just didn’t have any time for things like that any more.
There’s a lot of stress (壓力) in my job. Perhaps that’s why I started drinking more than I used to. For example, I used to have only half a glass of whisky when I got home, but then I started filling my glass to the top. Then I had another glass, and then another. __ 小題3:__ I never used to smoke at all.
Two months ago, I had a heart attack. At first I just couldn’t believe it. “I’m too young.” I said.  Luckily it wasn’t very serious. I was in hospital a few days and they did a lot of tests. __小題4:__ He also advised me to work less and get more exercise. But I just haven’t any time! __小題5:__
Sometimes I wonder if I should get another job. Perhaps I could do something like I used to do. But if I do that, I won’t earn as much. I have a family to support. I have to think of them, too. I just don’t know what I should do. What do you think?
A.Then, about eight years ago, I got a much better job.
B.My job takes everything out of me!
C.I rode a bike to work and I got a lot of exercise at weekends.
