try to do sth.不定式是作状语还是宾语?

try to do sth.不定式是作状语还是宾语? try to do sth 这里的不定式to短语是作宾语,那么这个时候try是及物动词还是不及物动词 请问及物动词在不定式中作目的状语的时候结构可以是"to+do"吗,还是一定得跟上sth,即to+do+sth want to do sth词性问题,这里want是及物动词吗?to do是不定式作宾语吗? he is sure to do sth 中 to do sth 做状语还是宾语 动词不定式作宾语的如：hope to do sth要至少20个,最好是初中英语单词 尽力做某事是try one's best to do sth.还是try to do sth. He wants to do it before lunch before lunch 是时间状语还是和不定式一起做宾语 try one's best 是to do sth还是doing sth还是do sth ability to do 中动词不定式 to do 作定语还是 目的状语? 英语句子成分I want you to do sth,这个句子中,to do sth是直接宾语,还是目的状语?这个句子和 I'm glad to do that.这里的不定式to do that在句中作什么成分啊?是宾语还是状语?
