3 Part1 Getting ready  Coronary heart disease  Heart attack caused when the blood supply to your heart is blocked.  冠状动脉血栓

4 Part II Heart attack  Most heart attacks are caused by a blockage of one of the coronary arteries by a blood clot. this cuts off the blood supply to part of the heart muscle, which then dies. The main symptom of a heat attack is a tight pain in the chest, which may spread to one or both shoulders and down the arms to the hand.

5 II***A  Heart attacks vary greatly in their nature. They may occur suddenly with little or no warning,or they may develop gradually. The pain can vary from a slight feeling of discomfort to a very strong bursting feeling in the chest. It may last for up to an hour, or it may disappear after a few minutes and then return.A person suffering a heart attack is also likely to feel sick, dizzy and out of breath.

6 II***B  A heart attack is a serious matter and should be treated as an emergency. Don’t try to travel to the doctor yourself, but stay with the patient and call an ambulance immediately.Keep the patient warm and as calm as possible. While you are waiting for help to arrive,lift the patient warm and as calm as possible.Put pillows or cushions behind the patient’s head and neck,bend the knees and loosen any tight clothing around the neck, chest and waist.Don’t give anything to eat or drink and don’t leave the patient alone. If the patient becomes unconscious, try mouth-to-mouth artificial respiration, and at the same time press down on the patient’s chest to force blood around the body.

7 II***B  When the ambulance arrives, the patient will be taken straight to hospital,and will probably be kept there for several days. The patient’s chances of recovery are good: two out of every three people who have a heart attack recover completely, and nearly half a million people recover from heart attacks in Britain every year.

8 Part Ⅲ Smoking kills  Until the twentieth century cigarettes were not an important threat to public health.Men used tobacco mainly in the form of cigars. Most women did not use tobacco at all. The cigarette industry manufacturing machine. This made it possible to produce great numbers of cigarettes very quickly, and it reduced the price.

9  Today cigarette smoking is a widespread habit. About forty-three percent of the adult men and thirty –one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of the women have stopped smoking. The number of persons who have given up smoking is increasing.

10  Men as a group smoke more than women.Among both men and women the age group with highest proportion of smokers is the age group Income,education,and occupation all play a part in detemining a person’s smoking habits.City people smoke more than people living on farms. Well- educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes. On the other hand, if a well-educated man with a higher income smokes at all, he is likely to smoke more packs of cigarettes per day. Among teenagers the picture is similar. There are fewer teenager smokers from upper-income, well- educated families, and fewer from families living in farm areas.. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school.Children are most likely to start smoking if one or both of their parents smoke.

14 Part Ⅴ Memory test :Sleeping Problem  For some reason Richard West has been having great difficulty in getting to sleep lately. Last night he thought it might help if he went to bed even earlier than usual, so at 9:30 he thought it might help if he went to bed even earlier than usual, so at 9:30 he lay down, closed his eyes hopefully,and began counting sheep. Thinking of all those energetic little animals jumping over fences made him feel energetic himself, so he stopped, went down stairs, and found the most boring book he had.It was a book called Home Rug-Making. At the end of an hour he had become quite interested in making rugs. He put the book down in desperation.Then he remembered someone telling him once that if you repeated “Sleep” often enough.it would finally come.15 minutes late the people in the bedroom above him tapped angrily on the floor.

15  At 2 o’clock he took a sleeping-tablet. It had absolutely no effect.  At 3 he got up and walked around his room at least 20 times.  At 4 he did a deep-breathing exercise.  At 5he stared at a spot on the ceiling until his eyes began to hurt  At 5 his eyes began to feel heavy and, finally,he dropped off.  His alarm-clock rang at 7

16  This morning at work his boss looked at him gravely,shook his head, and said in a critical tone of voice:” See here, West, you have been looking very tired lately ! obviously, you haven’t been getting enough sleep.I really think you ought to try going to bed earlier!”
