They knew it was good for their business. Now the officer got fatter and fatter. He could hardly go upstairs at home and had to sleep downstairs. He often felt tired if he walked or did some housework. He was worried about it and had to go to see a doctor.“Stop eating much fat (脂肪) and sugar, Mr.Jenkins，”said the doctor.“Or it will be worse for your health！”It was difficult for the officer to do it. He wouldn't do as the doctor said. Of course, he found something was wrong with his heart a few months later. Now he thought the doctor was right. And he had to be in hospital.“You must lose weight(减肥), sir，”said the doctor, “unless you want to die soon！”“Could you tell me a way to lose weight, please？”“You must do an exercise first.”“Which exercise？”“To move your head from side to side when you're invited to dinner！”36．Mr.Jenkins was often asked to dinner because ________.A．he liked fat and sugarB．he was ready to help othersC．he was friendly to the shopkeepersD．he was an important officer37．It was difficult for Mr.Jenkins to do everything so ________.A．he didn't go to dinner B．he began to do some exerciseC．he went to the doctor for help D．he had to take much medicine38．Mr.Jenkins was afraid________，so he went to the doctor again.A．to die B．to be thin C．to stop working D．to do housework39．What's the meaning of “To move your head from side to side when you're invited to dinner！”？A．To refuse others' invitation.B．To shake the head more often.C．To do exercise like moving his head from side to side.D．To accept others' invitation.40．Which of the following is true according to the passage?A．The doctor told Mr.Jenkins not to do too much exercise.B．The doctor told Mr.Jenkins not to move his head.C．The doctor told Mr.Jenkins not to go to dinner.D．The doctor told Mr.Jenkins to put on weight.DSometimes it may seem difficult to improve our health. If so，the following health habits may help you.●Eat breakfast every morning.Research shows that if you eat a meal in the morning you may not become too fat or eat too much during lunch. Eating breakfast can help people feel better through the day.●Get enough sleep.Poor sleep can influence our memory and learning. It can also cause traffic accidents! Studies show that people who don't get enough sleep seem to get into more accidents. So stay safe and get enough sleep!●Take a walk every day.Walking is an easy way to exercise. You'd better meet friends for a walk，not for a meal. As you walk，you will see the beautiful world around you. Once you try，you will find that adding a walk into your daily life is very easy.●Join social groups.Social groups can provide support. They might include sports teams，art or music groups. People in the group can offer advice and can help each other in difficult times. Also，being in a group keeps your mind busy. An active mind is a healthy mind!●Have a hobby.A hobby could be running，reading or making something with your hands. Hobbies help people to relax and rest. Hobbies bring us joy as well.41．You may have a good memory and learn better if you________．A．eat breakfast every morningB．have a good sleepC．take a walk every dayD．join a social group42．If you need help and want to help others，you'd better________．A．invite your friend to a mealB．make something with your friendsC．become a member of a social groupD．have a hobby43．Which of the following is TRUE?A．If you have breakfast every morning，you'll be fat.B．All the traffic accidents are caused by poor sleep.C．To take a walk helps you have a healthy mind.D．Having a hobby is a good way to relax.44．The passage is mainly written for________．A．students at schoolB．people who don't like runningC．students who never have breakfastD．people who want to improve health45．Which is the best title(标题)of the passage?A．Ways to Improve Your HealthB．Reasons for Keeping HealthyC．Good HabitsD．Breakfast and Exercise.四、任务型阅读(每小题2 分，共10分)Mr.Black lives by the sea.
