单元语法小专题(Grammar Focus) 语法精讲

一般现在时中实义动词have的用法在英语中,表示现在的状态或表示经常的、习惯性的动作的句子要用一般现在时。另外,表示主语具备的某种性格和能力的句子也要用一般现在时。在一般现在时中,往往含有always,often(经常),usually(通常), every day(每天)等标志词。

have作实义动词,意为“有;拥有;占有”,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。它的一般现在时的各种句式如下: 1.肯定句:主语+have/has…

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中。例如: I have a red telephone.我有一部红色的电话。

He has a brother.他有一个哥哥。

2.否定句:主语+don't/doesn't+have…例如: We don't have the key.我们没有钥匙。

She doesn't have a tennis ball.她没有网球。

3.一般疑问句:Do/Does+主语+have…?

肯定回答:Yes,主语+do/does. 否定回答:No,主语+don't/doesn't. 在一般疑问句结构中,当主语是第三人称单数时,助动词用does;当主语是非第三人称单数时,助动词用do。例如: —Does Eric have an uncle?埃里克有叔叔吗? —Yes,he does.是的,他有。

—Do they have a computer?他们有电脑吗?—No,they don't.不,他们没有。
