Question

-Nice to meet you, Mr. Smith.___ did you decide to come to Thailand and open a hotel?

-That's because I was rally tired when I was working in London.

A.When B.Why C.How long D.How

Answer

B

【解析】

句意：——Mr. Smith，见到你很高兴。你为什么决定来泰国开一家旅馆？——那是因为我在伦敦工作时累极了。

考查特殊疑问句。When何时；Why为什么；How long多久，多长；How怎样，如何。根据下文“That's because I was rally tired when I was working in London”可知，这里是提问原因，这里用why来提问。根据题意，故选B。
