2. 急！！在线等！高中英语不懂点（一）不定式

A不定式to的省略只能在一些特别的动词搭配下使用。常见的有help sb (to) do sth make sb (to) do sth let sb (to) do sth keep sb (to) do sth 这些动词常常省略不定式to
B不定式作宾语都是充当名词，也就是当你找出主语和谓语，那么剩下的就是宾语。出现了不定式，肯定是宾语。如果句中含有宾语，那么不定式充当宾语补足语
CHe is always the first to come to school. {He主语 is谓语 the first to 宾语补足语（就是说他第几个到的，用来修饰） to come to school，宾语）他总是第一个来到学校的
He is always the first one who come to school. {成分属于定语从句，who 引导的定语从句修饰one 也就是说 这个人是怎么样的 who以前的是一个典型的简单句，与后面构成复合句}
D have some firends to invite over{先来分析下，I 主语 have 谓语 some friends 宾语 已经有宾语了，那么to 的不定式充当宾语补足语}
最后祝楼主学习进步
