【语法提要】

一般现在时态中have的用法

一般现在时的谓语动词可以由be动词（前面已学过）或实义动词来充当。今天我们重点学习一般现在时态中have的用法。

1.定义：一般现在时可以用来表示现在的状态，主语的性格、能力以及经常性或习惯性的动作。

2.一般现在时态中have的用法：have意为“有”，表示所属关系，有人称和数的变化，其主语一般是人，有时也可以是物。

（1）have 用于复数名词、第一二人称单复数或第三人称复数代词作主语的句子中；has为have的第三人称单数形式，用于不可数名词、可数名词单数或第三人称单数代词作主语的句子之中。

例句:I have an orange.我有一个橙子。

Tom has a friend.汤姆有一个朋友。

（2）have/has作谓语时的句型转换。
