Answer 1

C

試題分析：考查定語從句和表語從句：第一空是定語從句，先行詞是the reason，定語從句中g(shù)ave缺少賓語，用that或which引導(dǎo)定語從句，第二空是表語從句：表示…的原因是…要用句型：(one)reason(for...)is that...句意：她遲到的原因是她忘記設(shè)定鬧鐘了。選C。
點評：定語從句的考查主要就是考查關(guān)系詞的辨析，關(guān)系代詞that, which, whose, whom, as， who在句中做主語，賓語，表語或者定語；where, why, when在句中做狀語。要分析句子成分，看缺少什么成分，就選用相應(yīng)的關(guān)系詞。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(guān)鍵在于分析清楚句子結(jié)構(gòu)。通過判斷引導(dǎo)詞在從句中所作的成分及意義，來選擇正確的引導(dǎo)詞。
