i'd like to help pitch in with dinner.中的help与pitch在语法上是什么关系。 i want to leave the stew to simmer for 5 minutes.中为什么simmer不是被动语态to be simmered.

Answer 1

第一句是病句， 语法上虽然没错 help (to) do sth, 但语义上to pitch in并不是help的宾语，而是并列谓语动词， 句子应当是： I'd like to help and pitch in with the dinner. 或省略help， 因为pitch in包含帮助的意思， I'd like to pitch in with the diner.

第二句，simmer不用被动的， 类似中文"鸡汤炖2小时就够了。" 不说”鸡汤被炖2小时...“
The stew simmers for 5 minutes.

追问

to simmer是不定式做目的状语吗。

追答

是不定式作宾语补语， leave the stew to simmer, 让这个炖菜炖5分钟
