ТЕКСТ ЗАДАНИЯ

Task 1. Read a radio interview with a famous cardiologist. For questions 1-3 decide whether the statements are TRUE or FALSE.

Interviewer: Now, Welcome to “You and Your Health”. Today on our show we have the famous cardiologist Dr. Shaw. First of all maybe you could explain to us why the numbers of people suffering from heart attacks seem to be on the increase these days?

Dr Shaw: Well, I think the answer to that is, unfortunately, our modern lifestyle.

Interviewer: could you be a little more specific please doctor?

Dr Shaw: Yes, of course. Most of people underestimate the importance of a healthy diet. For example, how many times have you been too busy to eat a proper meal and so end up eating some unhealthy take out food?

Interviewer: So, what your are telling us is that if we all make an effort to eat healthier food we are less likely to suffer from heart problems.

Dr Shaw: Of course a healthier diet is going to help. Exercise is also important. We should all make sure we get a regular amount of daily exercise.

Interviewer: You mean we should all join a gym or buy exercise machines?

Dr Shaw: Only if you have the time and the money. If not just spend thirty minutes a day doing a physical activity such as walking, cycling, gardening or even dancing, you will be helping your heart as well as strengthening your muscles and increasing your lung capacity. In fact, if I had to describe a potential heart attack victim it would be a man in his 50s with a stressful job and a family to support, who drinks a lot of coffee, smokes cigarettes doesn’t eat proper balanced meals and gets very little exercise.

Interviewer: Well, thanks Dr Shaw, you have certainly given us a lot to think about.

2. If you have a healthy diet, with lots of fruits and vegetables, you don’t have to exercise.
