Why are we always tired, do you know? Firstly, if we can't sleep w, we will be tired. But we are often too busy. We can't finish our work in the day and we mdo it at night. We go to bed l and get up early. So we c sleep well. Most people n eight hours and some more. If we sleep for only five or six hours a night, we m be tired.

    Secondly, when we are ill, we will be t, too. But we don't know we are ill. So if you are always tired, maybe you are not so h. You'd better go to see a doctor.

    Thirdly, maybe you can't eat some kinds of food like eggs, nuts, meat or chocolate. If you are ill and tired after eating some food, please d eat it again to see if you are well.

    At last, if the a around you isn't nice and clean, you will feel tired. So please open your window often or go out for a walk and you will feel better.

— She is busy (answer) the telephone.

— Sure,         .

— OK! I'll remember          it here.

A farmer who lived in a small village had a bad pain in the chest. This never seemed to get any better. The farmer decided that he would go to see a doctor in the nearest town. But as he was a miserly(小气) person, he thought he would find out how much he would have to pay the doctor. He was told that a sick person had to pay three pounds for the first visit and one pound for the second visit. The farmer thought about this for a long time, and then he decided to go to the doctor in the town.

As he came into the doctor's room, he said, "Good morning, doctor. Here I am again." The doctor was a little surprised. He asked him a few questions, checked his chest and then took the pound which the farmer insisted on giving him. Then the doctor said with a smile, "Well, sir, there's nothing new. Please go on taking the same medicine I gave you the first time you came to see me."
