stay by his side 为什么这样说,stay不是及物动词吗?不可以直接把by去掉吗?
我看到很多动词后面都会加介词
Looking ahead the OPEC secretariat forecast non-OPEC supply next year to grow by more than the demand for oil.
这句话grow by 如果不加by呢?
因为grow和stay不都是及物动词吗?

stay by his side的by不是搭配stay而是搭配side的.
by one's side意思是在xx身边.也可以说stand by my side.
grow by这个句子后面的意思是说石油的供给量会增长到比石油的需求量更高.
这里的by是说会增长到xxx.后面接不同的介词有不同的意思.

by one's side是固定搭配的词组 意思就是在。。。的旁边 不可以拆开或者省略
