VI. Read the passage below and choose the best answer A, B, C or D to each question.
I’m interested in sports, especially athletics, and I run seven or eight kilometres every day. I particularly enjoy cross country running, where you have to run across fields, jump over streams and so on. While I’m running I think about all sorts of things, and at the end of a run I’m sometimes surprised to find that I’ve managed to solve a problem that was on my mind.
Next year, I’m going to try the London Marathon. It’s hard race 26 miles, or 42 kilometres-and you have to be tough to finish, but I very much want to do it. I worry a bit about getting too old, and I’d like to prove to myself that I’m still almost as fit as I was twenty years old.
I’m interested in mountaineering s well as running. I’ll never become an except climber, but I know what I’m doing in the mountains. I successfully completed a course in snow and ice climbing when I was younger; and I’ve done a series of easy climbs in the Alps during the last few years. My wife doesn’t share my interest in mountains. She agreed to go climbing with me once, but she found that she felt ill as soon as she got above 1,000 metres.
The writer takes up mountaineering because ____.
A.he wants to become an expert climber
B.he simply likes it
C.his wife is interested in it
D.it is easy to practise
