Some of my friends are interested in science,but none of them can tell_____.

A．when UFOs will appear next time.

B．why do horses know the way.

C．where was this kind of plant found.

D．how do elephants communicate.

Answer 1

A

试题分析：句意：我的一些同学对科学感兴趣，但是他们没有人能讲出下次UFOs将何时出现。宾语从句如果是特殊疑问，那么特殊疑问词要放在宾语从句的句首，后面+陈述句的句序结合语境可知选A。
