LZ.......那是help do！！的用法呀。。。。the structure helps explain why。。。。。

bontakuner

。。。。。我知道那是help do啊，我就是想知道为什么一个句子两个谓语动词啊

nesstang

explain不是谓语动词。。。。help是谓语动词。。。。是帮助explain，不是explain。。。。主语是在help，help才是谓语。我是这么理解的。

lz呀。。。。help do sth=help to do sth（就是将to省略了。。。。两种形式可通用。。。）你把to带进来，应该能理解了吧。。。。动宾结构呀。。。。。

LZ.....两种用法都可以啦！！！！！！！出题人开心用哪个就用那个，确定的是两种用法都对,保证help 后面加的是动词原形就行了，且意思是一模一样滴!!!!!!!!
LZ不必纠结了。。。。。记得这个用法吧
