Question

he started to shout and sing.这里为什么是sing而不是to sing?and不是连接并列成分的吗?

Answer 1

当对等连接词连接的并列成分是动词不定式的时候,我们可以把后面一个动词不定式省去to,如：
I am really puzzled as to what to think or say.
It is just impossible to see that and not weep.
但是两个动词不定式有对照或对比之意时,不可以省去to,如：
To be or not to be--that is the question.
I came not to scold,but to praise you.
你给出的句子也是一样,and连接两个动词不定式时,后面的动词不定式省去to.
希望我能帮助你解疑释惑.
