英语中的不定式相信大家都不会陌生，GMAT语法中涉及到不定式的考试内容众多，可以算是相当高频的一个考点。但不定式虽然常见，有时候难度高起来也会让考生觉得头疼。下面是小编为大家整理收集的关于GMAT语法不定式考点的真题解析，希望对大家有所帮助。
GMAT语法不定式常见用法介绍
不定式在句子中可以充当很多成分，如名词，形容词或副词：
◆ Noun: I love TO SWIM. To swim 作为love 的宾语.
◆ Adjective: The person TO MEET is here. To meet 修饰名词person .
◆ Adverb: Sue paused TO EAT lunch. To eat 修饰动词paused .
实例对比不定式正确错误用法
对于不定式的使用，我们也更应该关注不定式所要表达的目的：
Right: The contractors demolished the building TO KEEP it from falling down accidentally. demolished 的发起者是contractors ,同时也是不定式to keep的发起者，它描述了demolish 的目的，这里的it 指代building。
我们再看一个例子：
Wrong: The building was demolished TO AVOID falling down accidentally. 例子中building 本身不可能AVOID falling down，对于上面例子可以这样修改：The building was demolished TO KEEP IT from falling down accidentally. 这里的it 指代building ，经过这样修改，building 变成了不定式的宾语。不定式虽然可騨发名词用但还是和名词有许多不同的地方，比如不能作为介词的宾语。
