怎么改反义疑问句？

Let us have a rest, will you?

There is no time to go shopping, is there?

肯定对，不懂问我

Let us have a rest, will you?

There is no time to go shopping, is there?

Let us have a rest, will you?
Let us分开则都用will you
Let's缩写则都用shall we

There is no time to go shopping, is there?
there be句型主语都为there
因为有否定词no，所以反意疑问句应为肯定，用is，不是isn't
