i (look at) a football in his baglook at 为什么不能用see
i (look at) a football in his bag
look at 为什么不能用see

i (look at) a football in his baglook at 为什么不能用see
look本身是不及物动词不可直接加宾语的,所以加at,
而see既可作为及物动词用,又可作为不及物动词用,
例:.I went to the hospital to see him.(及物动词)
2.To see is to believe.(不及物动词)

这个是要用动词的适当形式填空的题目吧!
I am looking at a football in his bag. 现在进行时
也可以用see
I see a football in his bag. 一般现在时
