问题描述:
Lily has to finish her homework first,-----she?
A.doesn not
B.has not
说明原因,
答
A.
分析如下:
前句中Lily 和 has to之间省略了助动词does
而反义疑问句中,逗号后面的be动词或助动词要与前面相反,如:
—She (is) a girl,(isn't) she?
__He (didn't) finish his homework,(did) he?
{明白了吗}
答
A。has to不是情态动词,在这里与to结合使用,是固定用法。
答
A has to 在这里是不得不的意思,她有单三形式变化,后面用does
答
B
