Question

—Are those Jenny's pencils?

—________. They are Mary's.

A.Yes, they are B.No, they aren't C.No, they don't D.Yes, they do

Answer

B

【解析】

句意：——那些是珍妮的铅笔吗?——不，它们不是。它们是玛丽的。

考查一般疑问句。Yes, they are是的，他们是；No, they aren't不，他们不是；No, they don't不，他们没做；Yes, they do是的，他们做了；根据“Are those Jenny's pencils?”及“They are Mary's”可知此处是表示否定，结合“Are those…”的否定是“No, they aren't”，故选B。
