主要行为动词后面的动词采用了“t+动词原形”的结构，我们把这种结构称为动词不定式（有时可以不带t）。动词不定式没有人称和数的变化，在句子中不能做谓语。
T make yu understand him cmpletely is impssible.We decided t begin the experiment in the afternn.
1.不定式做宾语补足语：动词不定式可以用来说明宾语的情况，做宾语补足语。
My mum asks me t play the pian tw hurs every day.I knw nthing abut him and I beg yu t tell me smething.She tld me t buy a ticket fr her.
1.常接不定式做宾补的动词有warn，tell，allw，ask，rder，get，invite，wish，want，encurage等(+sb. t d sth.)。
The teacher tld me t clean the blackbard.
He rdered the girl t wash the bike at nce.
2.以上动词接不定式做宾语补足语时，若要表达否定的意思，要在t d前加nt，构成nt t d的形式。
Mr. Han tld us nt t make t much nise.
3.有些动词后接不定式做宾语补足语时，要接不带t的不定式(也就是说接动词原形)，常见的这类动词有make，let，have，hear，feel，see等。

2.动词不定式做目的状语：如果表示“做某事是为了什么”，可以用动词不定式表示目的，做目的状语。

1.动词不定式做目的状语时，既可以放在句首，也可以放在句尾。
