Unit5 语法
一般现在时中have的用法 Unit5 Grammar Focus
1.用法
have作实义动词,意为有,其主语一般为人,强调某人拥有某物,有时也可以用物作主语;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 books. 我的朋友有很多书。
I have a new bag. 我有一个新包。
Mike has a dog. 迈克有一只狗。
2.句式 一般现在时中have的句式结构
3.考点表所属关系,看清人称,找准助动词。
考向:辨析have/has与there be
have/has表示所属关系,即某人或某物有什么。
eg. I have a sisiter. 我有个妹妹。
there be表示存在,即某地有某物,遵循就近原则
eg. There are boys in the room. 房间里有一些男孩。
注意:当表示某物的构成或组成成分时,用there be句型或have/has均可。
eg. There are fifty students in our class.
= Our class has fifty students.
我们班有50个学生。
考题在线1
—______ she have a soccer ball?
—No, she ______.
A. Is; isnt B. Does; doesnt
C. Does; dont D. Do; doesnt
解析:本题用题眼法。看到代词she和动词have能判断出本题是在考查实义动词的一般疑问句,主语为she(她),属于第三人称单数,所以使用助动词does,否定回答用doesnt。故选B。

Look!There ______ a photo of our English teacher in Todays newspaper!
A. is B. are C. have D. has
解析:考查固定句型。there be......表示某地有某物,不能和have/has同时出现在一个句子中,故排除C、Dl两项。there be句型遵循就近原则,由后面的名词 a photo(一张照片)是单数可知be动词用is。故选A。
链接中考:
He has four lessons in the morning every day.(改为一般疑问句)
______ he ______ four lessons in the morning every day?
解析:可用语法判断法解答本题。句子的时态为一般现在时,谓语动词has为实义动词,且主语为第三人称单数,变为一般疑问句时要借助助动词does,且has要变为have。故填Does;have。
have的用法口诀:
have/has表示有,位置就在主语后;
三单主语用has,其他人称用have。
一般疑问很好变,do或does句首站;
变为否定也不难,have之前dont/doesnt添;
do或does句中现,have要把has换。
