题目内容
20.The children will climb the hill if it ______ tomorrow.( )| A. | won't rain | B. | didn't rain | C. | isn't raining | D. | doesn't rain |
分析 如果明天不下雨,孩子们将要去爬山.
解答 答案:D 根据if可知,整个句子是含条件状语从句的主从复合句.意思是"如果";当主句是一般将来时态,从句用一般现在时态,主语是it,谓语动词用第三人称单数形式,故选D.
点评 本题考查状语从句,if引导的是条件状语从句,当主句是一般将来时态,从句应该用一般现在时态,我们称之为"主将从现".
