I是个字母。在语言中，第一人称、第二人称、第三人称分别是指“我”、“你”、 “他（她）” 也就是说除了“我”“你”以外，其它的人称都属于第三人称，而这个人称所指的人或物只有一件时就称作第三人称单数！那么第三人称，就是指“他”或者“她”。 接下来，什么是“单数”和“复数”呢？ 巩固练习题： I.写出下列动词的相应形式： 1. 第三人称单数： wash_ match _guess_ study_ finish_ go_ snow_ carry_ 2.写出下列动词的过去式：stop_ see_ drive _let_ carry_ keep_ join_ find_ think_ teach_ catch_ 3. 写出下列动词的现在分词形式： stay_ begin_ forget_ forget_ lie_ die _ run_ prefer_ give_ ring_ dance_ hope_ II. 用所给动词的适当形式填空： 1I _(write) to you as soon as I _(get) to London. 2.
