用英语介绍我一天的食物
答案
I like apple very much, because first it is very beautiful. It is red and round. You can not help eating it when you see it; second, it is very sweet. It is rally a kind of enjoyment when you taste it; third, it is said that apple is very good for your health. There is a proverb said ‘ one apple a day, keeps doctor away. It means that if you have one apple everyday, you won’t get any disease. Amazing! Right? You see, apple is not just a ordinary fruit. It can also keep you away from disease, so there is no reason to refuse such good fruit. Try it and enjoy it!
