2024年英语中考语法专项：时间状语从句&专项练习讲义

中考语法专项：时间状语从句&专项练习 1． 定义： 时间状语从句是在复合句中充当状语，用于表示主句动作发生的时间的从句。 简单来说，它描述了一个动作发生的时间背景，通过特定的引导词（如 when、while、as、before、after、since、until 等）将这个时间信息与主句的动作联系起来。 例如：“When I was a child, I often played in the park.” （当我还是个孩子的时候，我经常在公园玩。）在这个句子中，“When I was a child”就是一个时间状语从句，它说明了主句“ I often played in the park”这个动作发生的时间。 2． 引导词 引导词的选择：如 when、while、as、before、after、since、until 等的正确使用及区分。 when 可接短暂性动词和持续性动词。 while 只能接持续性动词。 as 强调主从句动作同时进行。 常见的时间状语从句的连词有： 1.when：表示“当......的时候”，从句动作可与主句动作同时发生，也可先于主句动作发生。 例如：When I got home, my mother was cooking. 2.while：强调主句动作和从句动作在同一时间内同时进行，从句动作通常是延续性的。 例如：While I was reading, my sister was playing the piano. 3.as：意为“当......时；一边......一边......”，强调主从句动作同时发生。 例如：As I walked along the street, I saw many beautiful flowers. 4.before：“在......之前”。 例如：Please close the window before you leave. 5.after：“在......之后”。 例如：After he finished his homework, he went to bed. 6.since：“自从......以来”，主句通常用现在完成时。 例如：I haven't seen him since we graduated. 7.until / till：“直到......为止”，用于肯定句时，主句动词是延续性的；用于否定句时，主句动词是非延续性的。 例如：I waited until he came. / Don't leave until I come back. 8.as soon as：“一......就......”。 例如：I'll call you as soon as I arrive. 三．时态的搭配： 主将从现：主句一般将来时，从句用一般现在时表将来，如：I'll call you when I arrive. 主过从过：主句过去进行时，从句用一般过去时，如：I was doing my homework when my mother came in. 句子的理解和翻译：需要准确理解时间状语从句在整个句子中的含义，并能正确翻译成通顺的中文。 例如： He was reading a book while his sister was playing the piano. （考查 while 的用法） I haven't seen him since he left. （考查 since 的用法及现在完成时） Don't go out until the rain stops. （考查 until 的用法） 专项练习 一、选择题 1.I'll visit you _ I'm free tomorrow.
