动词不定式做宾语补足语
动词不定式在句子中可以用作宾语补足语，常用的“动词+宾语+不定式”的句子结构中，不定式作宾语补足语的有以下几种类型：(下列句子中划线部分作宾语补足语)
一、许多动词可跟一个“宾语 + to do…”构成句子，句中的不定式作宾语补足语；否定形式为“动词+宾语+not to do…”。
例如：
My boss told me to type out two letters.
分析：句中“My boss”做主语，“told”作谓语，“me”作宾语，划线部分作宾语补足语。
请看下面的句子。
They forbid her to leave the country.
适用于“动词+宾语+(not)to do…”的结构，不定式作宾语补足语的动词有：advise，allow，ask，beg，cause，direct，encourage，expect，forbid，force，invite，order，permit，persuade，remind，request，require，teach，tell，want，warn等。
二、有些动词(感官动词和使动词)后可跟不带to的不定式构成句子，句中的不定式作宾语补足语。
例如：
He saw her enter the room.
分析：句中“He”做主语，“saw”作谓语，“her”作宾语，划线部分作宾语补足语。
请看下面的句子。
She won't let me do it.
I heard her lock the door.
适用于“动词+宾语+do…”的结构，不定式作宾语补足语的动词有：feel，have，hear，let，make，notice，observe，see，watch等。
还有两个词组：listen to，look at。
三、help后的不定式可加to，也可不加to(美国人不加to时较多)，但被动结构中要加to。
如：I'll help you(to) push the car.
分析：句中“I”做主语，“will help”作谓语，“you”作宾语，划线部分作宾语补足语。
