18．The train was late，____we had to wait for half an hour．（　�。�
A．becauseB．orC．soD．but

分析 火車晚點了，所以我們不得不等半個小時．

解答 答案：C；because因為；or否則；so所以；But但是．because和so都可以引導原因狀語從句，because只能放在句子中間，在它之前的是結(jié)果，后面的是原因．so做所以解釋時也是放在句子中間，在它之前的是原因，后面的是結(jié)果．根據(jù)句意，"火車晚點了，我們不得不等半個小時"可知該句為原因狀語從句；因為"we had to wait for half an hour"是結(jié)果，故用so連接；故選C．

點評 根據(jù)句中信息推測出該句的句意是解答此題的關鍵；還要對給出的四個連詞進行分析和比較，從而作出正確解答．
