He thinks two donuts are good for him.为什么不用well?(my trousers are too small for h

• my trousers are too small for him,he has to put on his own(为什么不用his own one)
• he smiled and waved to the crowds waiting for him 为什么要用waiting
• He can speak English very well为什么不用good
• he always thinks more of himself than others ,so nobody likes him 为什用others不用other ,the other,the others???

my trousers are too small for him,he has to put on his own(为什么不用his own one)

trousers复数，用 one不合适。所以省略。

he smiled and waved to the crowds waiting for him 为什么要用waiting

一句句子只能有一个动词对吗 那么这句话里有2个动词 smile和wave 对吗 因为有and这个连接词。一个连接词只能连2个动词。那么wait不再能当动词用。这里waiting是动名词 表示和它的逻辑主语（the crowds) 主动的关系~

He can speak English very well为什么不用good

因为very是形容词，修饰的是副词，而good是形容词，并且副词和形容词同时用的时候，副词在后，形容词在前！

he always thinks more of himself than others ,so nobody likes him 为什用others不用other ,the other,the others???

表示“比……更多” 此时more为many或much的比较级，表示数量，后接名词！other是形容词，the other,the others则是代表另个一，其它的，都与题意比较级不符，故用others
