一般现在时中have的句式结构

there be 表示存在,即“某地有某物”,遵循“就近原则”

考题在线1
—______ she have a soccer ball?
—No she ______.
A. Is; isn't B. Does; doesn't
C. Does; don't D. Do; doesn't
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doesn't。故选B。
考题在线2
Look!There ______ a photo of our English teacher in Today's 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don't/doesn't添;
do或does句中现,have要把has换。

二、6.B 解析:本题用题眼法。主语Tim是第三人称单数,故谓语动词用第三人称单数形式,否定形式应为doesn't 动词原形,所以选B。
