语法精讲
一般现在时中have的用法
1．用法
have意为“有”，强调某人拥有某物，用于一般现在时中有两种形式：have和has 。

当主语是第三人称单数时用has，其他人称用have。

eg：My friend has many toys.我朋友有很多玩具。

I have a new bag.我有一个新书包。

【助记口诀】
动词have表示“有”，位置就在主语后。

“三单”主语用has，其他人称用have。

一般疑问句很好变，句首直接把do/does添。

否定句子也容易，don't/doesn't加在have/has前。

does/doesn't句中现，has要用have来替换。
