Question

【题目】Eric is wondering ________he could climb to the top of the mountain as he was too tired to do that.

A.ifB.thatC.which

Answer 1

【答案】A

【解析】

句意：埃里克想知道他是否能爬到山顶，因为他太累了，爬不上去。

考查宾语从句。if如果，是否；that无意义，在从句中不作成份；which哪一个；根据题干中“as he was too tired to do that”可知他不确定自己能否登上山顶，由此可推出此处是说“Eric想知道他是否能爬到山顶”，用if表示“是否”。故选A。
