【题目】—An explosion (爆炸) happened in Yanchen several weeks ago.

—I wonder ________.

A.when did the accident happenB.what caused the terrible accident

C.how many people are killed in the accidentD.how did the government help solve the problem

Answer 1

【答案】B

【解析】

句意：——数周前盐城发生了一起爆炸事件。——我想知道是什么引起了这场严重的事故。

考查宾语从句的时态和语序。when did the accident happen事故是什么时候发生的；what caused the terrible accident是什么导致了这场可怕的事故；how many people are killed in the accident有多少人在事故中丧生；how did the government help solve the problem政府是如何帮助解决这个问题的；根据时间状语several weeks ago.判断从句是陈述发生在过去的事情，用一般过去时，排除一般现在时的选项C；根据宾语从句要按照陈述句的语序的原则，排除是疑问句语序的A和D； 故选B。
