Question

I think that“Da Call” must be one of the hottest words on the Internet in 2017, but I don’t know _________.

A.what does it mean B.how it became popular

C.whom was it first used by D.why do people like using it

Answer

B

【解析】

句意：我认为“Da Call”一定是2017年互联网上最热门的词汇之一，但我不知道它是如何流行起来的。

考查宾语从句。A、C、D三项都是疑问语序，B项是陈述语序。宾语从句中从句要用陈述句语序，根据“but I don’t know _________.”由此可知要用B项how it became popular表示“它是如何流行起来的”。故选B。
