动词不定式作宾语补足语是英语中常见的语法现象，指的是用“to+动词原形”的结构补充说明宾语的动作、状态或身份，使句子意义更完整。其基本结构为：主语+谓语动词+宾语+动词不定式（todo）。Presentation动词不定式作宾语补足语一、常见可接不定式作宾补的动词分类

并非所有动词都能接不定式作宾补，以下是几类典型动词：

1.表示“命令、要求、允许”的动词

这类动词后接不定式作宾补时，强调对宾语的指令或许可，常见动词有：ask,tell,order,allow

等。

例句：

Mymother

told

me

toclean

theroom.

妈妈叫我打扫房间。

Theteacher

allowed

us

toleave

early.

老师允许我们早点离开。Presentation动词不定式作宾语补足语2.表示“希望、期望、想要”的动词

这类动词侧重表达主语对宾语的期望或意愿，常见动词有：want,wish,expect等。例句：Iwantyoutohelpmewithmyhomework.我想让你帮我辅导作业。Theyexpecttheteamtowinthegame.他们期待这支队伍赢得比赛。Shewisheshimtostayfordinner.她希望他留下吃晚饭。Presentation动词不定式作宾语补足语二、不定式作宾补的否定形式

不定式的否定形式是在to前加not，即“nottodo”。

例句：Thedoctoradvisedhimnottodrinktoomuch.

医生建议他不要喝太多酒。Parentstoldtheirkidsnottoplaywithfire.

父母告诉孩子们不要玩火。Presentation动词不定式作宾语补足语三、it作形式宾语时的宾补结构

当宾语是不定式短语时，常用it作形式宾语，将真正的宾语（动词不定式）放在宾补之后，结构为：主语+谓语+it+宾补+动词不定式。

例句：Ifinditdifficult

tolearnFrench.我发现学法语很难。

（it是形式宾语，tolearnFrench是真正宾语，difficult是宾补）Shemadeitarule

toreadforanhoureveryday.

她定下规矩，每天读书一小时。

Presentation动词不定式作宾语补足语四、需要注意的特殊情况let,make,have这三个使役动词在主动句中接不带to的不定式作宾补，但被动语态中需加to：

主动语态：Theteachermadeusstudyhard.

老师让我们努力学习。

被动语态：Weweremadetostudyhardbytheteacher.help后接不定式作宾补时，to可带可不带：Hehelpedme(to)carrythebox.他帮我搬箱子。
