Question

【题目】—He's already back to the USA, __________?
—_________.He is on a business trip in Suzhou.
A.isn't he; Yes
B.hasn't he; No
C.hasn't he; Yes
D.isn't he; No

Answer 1

【答案】D
【解析】句意：——他已经回到美国了，不是吗？——你说得对。他正在苏州出差。反义疑问句，前半句是肯定句，后半句是否定形式，助动词是is，故第一空用isn't。根据He is on a business trip in Suzhou.可知他没有从美国回来，故此处用否定回答，故第二空用No，故选D。
