Question

Why are you always tired, do you know?
First, if(如果) we can’t1well, we will(将) be tired. But we are often too2. We can’t finish our work in the day3we have to do it at night. We go to bed 4and we get up early in the morning for school or work. Most people need at least(至少) eight 5  or some more. If we sleep for only five or six hours a night, we will be tired.
Second, when we are ill, we will be tired. But we don’t know we are ill. So if you are always tired, maybe you are not so 6. You’d better go to see a 7 .
Third, maybe you eat 8food, like hamburgers, meat, chocolate or coffee. If you are ill and tired after eating some food, please don’t eat it 9 to see if you are well. 
At last, if the air around you isn’t nice and clean, you will feel tired. So please open your windows often or go out for a walk and you will feel 10.
