Firstly if we can't sleep 1 , we will be tired. We often have too 2 work to do. We can't 3 our work in the daytime and we must do it at 4 . We go to bed very 5 and get up very 6 . So we can't get enough sleep. Most people need at least eight hours of sleep. If we 7 for only five or six hours a night, we will be tired. Secondly, when we are ill, we will be tired. But we don't know we are ill. So if you are always tired, perhaps you are not so healthy. You'd better go to see a 8 . Thirdly, perhaps you shouldn't eat some kinds of food like eggs, nuts, meat or chocolate. If you are 9 and tired after eating some food, please don't eat again.
