探究点1 动词不定式作定语
1. 动词不定式作定语, 可修饰人和物。
当中心词为序数词、最高级、the last、the only等, 或被这类词修饰时, 其后一般用动词不定式作定语;不定代词后也应用动词不定式作定语。
2. 作定语的动词不定式如果是不及物动词, 或者动词不定式所修饰的名词或代词是动词不定式动作的地点、工具等, 动词不定式后面须有相应的介词。但是, 动词不定式所修饰的名词如果是time、place或way时, 动词不定式后面的介词习惯上省略。
Please give me a knife to cut with. 请给我一把切东西用的刀。
Here is some paper for you to write on. 这里有一些纸给你写字。
He had no money and no place to live (in). 他没有钱也没有地方住。
We found a way to solve this problem (in). 我们找到了解决这个问题的方法。
I’ve grown so crazy about everything to do with nature.

3. 当作定语的动词不定式所修饰的名词或代词是动词不定式动作的承受者时, 动词不定式既可以用主动语态, 也可用被动语态, 但其含义有所不同。

你有什么要寄的东西吗? (动词不定式to send 的动作执行者是“你”)
Have you anything to be sent?
你有什么要(我或别人)寄的东西吗?
(动词不定式to be sent 的动作执行者是“我”或“别人”)
