Question

—I drove to Zhuhai for the air show last week..
—Is that ________ you had a few days off ?

A．where

B．when

C．what

D．why

Answer 1

D

試題分析：考查表語從句。句意：—我上個星期開車去珠海看航展。—那就是你請了幾天假的原因嗎？本句中的why you had a few days off是一個表語從句，why在句中做原因狀語。故D正確。What要在句中做主語，表語或者賓語等成分。AB兩項的語義與句意不相符。故D正確。
點評：連接表語從句的連接詞有：that, what, who, when, where, which, why, whether, how, whoever，whomever，whichever ，whatever等。還有如because, as if, as though等。解答這類題目，關鍵在于分析清楚句子結構。通過判斷引導詞在從句中所作的成分及意義，來選擇正確的引導詞。
