Reading 1 Read the texts about sleep problems. Match the sentences (1–6) with the people (A–C). You can choose the people more than once. Which person: 1 has ignored his/her doctor’s advice? ……………………. 2 has a problem which few people know about? …………………….. 3 has trouble getting to sleep? …………………….. 4 has had to change his/her life because of the problem? ……………… 5 says his/her problem is more serious than people think? ......................... 6 is getting help for his/her problem? ………………….

When you snore it means that you can’t keep your throat open when you’re asleep. In my case, I actually stop breathing for ten seconds or more. It worries my wife but I always wake up afterwards! B.

Since the problem started I’ve had to stop working because you can’t do a good job if you fall asleep in the middle of a conversation! My friends have been very supportive but I don't like going out now because I get embarrassed about it and also I’ve had to stop driving as it’s much too dangerous. I go to a special sleep clinic now and they’re helping me a lot. C. Robert I’ve had this sleep problem since I was a child and I know a lot of people who have the same problem. It’s called insomnia and it means I sleep very badly. Sometimes I can’t get to sleep for hours and sometimes I go to sleep OK, but I wake up in the middle of the night and then I can’t get back to
