| Is food important for us? The answer is YES. If we do not eat 1 , we will feel hungry. If we can not find food when 2 are hungry, we may feel very 3 . Maybe we can become sick, then die later. Now we have another problem, if we eat, what kind of food is 4 for us? Is meat better than vegetables and fruits? 5 vegetables and fruits 6 than meat? For some people, it is very easy to answer this 7 : Vegetables and fruits are surely(一定) better than meat, because they 8 eat meat. For most of us, it is not very easy to decide on 9 is better. Doctors say it is not really important for us to decide on which is better, meat or vegetables and fruits, but it is 10 to take a balanced diet of meat and vegetables and fruits. | |||
