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或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。它的一般现在时的各种句式如下：
1．肯定句：主语＋h ave/has…
have用于复数名词,第一人称单复数、第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,常借助助动词do,当主语是第三人称单数时,助动词用does。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。语法精练
