实义动词的一般现在时 一、什么叫实义动词？ 实义动词是指表示某种动作行为,有具体意思的动词,也叫行为动词。如: like, eat, live, have, run 等等，它们的意思分别是：“喜欢”、“吃”、“居住”、“有”、“跑”等等，这些都是实义动词。实义动词占英语中动词的绝大多数。
我们已学过的be 动词可译成“是”，有时译成“成为”，有时则没有具体意思如： “She is tall.”这句译成： “她很高”。故be 动词不属于实义动词。
二、人称的划分 1. 第一人称: I, we 第二人称: you 第三人称: he, she, it, they, Millie…
2. 第三人称单数:第三人称中指一个人或事物的代词或名词,如: he, she, it, Millie, his friend, the dog等。 ？ 你能再举出一些第三人称单数的例子吗？
三、 一般现在时实义动词作谓语时 的动词形式： 一般现在时实义动词作谓语时的动词形式有两种:动词原形或第三人称单数动词形式(如: enjoy叫原形, enjoys叫第三人称单数形式)。
