期末语法复习 8上（旧）·鲁教版（五四制）·时间和条件状语从句 一、核心考点解析 考点一：时间状语从句的引导词及基本用法 规则：常用引导词有when(当…时)、wile(当…时，主句和从句动作同时进行， 从句常用延续性动词)、as soon as(一…就…)、ntl(直到…为止)。其中when 既可以引导短暂性动词也可以引导延续性动词，wle引导的从句通常用进行时态。 真题再现（鲁教8上期末真题改编）： I was doing my homeworkmy mother came back. A)when B)while C)as soon as D)until 答案：A 解析：主句为延续性动作(was doing),从句为短暂性动作(came back),故用when。 例题练习： He will call you he arrives in Beijing. 答案：as soon as 解析：表示”一到达就打电话，用as soon as。 考点二：条件状语从句的引导词及”主将从现”原则 规则：常用引导词有if(如果)、less(除非，如果不)。当主句为一般将来时、祈使 句或含有情态动词时，条件状语从句要用一般现在时表示将来，即”主将从现”。 真题再现（鲁教8上期末真题改编）： Ifit tomorrow,we will stay at home. A)rain B)rains C)will rain D)rained 答案：B 解析：主句为将来时(will stay),从句用一般现在时(rains)。 例题练习： You will pass the exam.You study hard.(用if合并句子) You will pass the examyouhard. 答案：if;study 解析：主句将来时(will pass),从句用一般现在时(stdy)。 考点三：until引导的时间状语从句的用法 规则：l表示”直到…为止”，主句为肯定句时，谓语动词用延续性动词；主句为 否定句时，构成otnt1.”结构，表示”直到…才…”，谓语动词用短暂性动词。 真题再现（语法填空）： She didn't go to bed she finished her homework. 答案：untl 解析：主句为否定句(didn't go),用not.untl结构。 考点四：时间和条件状语从句中常见引导词的辨析(when与whle) 规则：when引导的时间状语从句中，主句和从句的动作可以有先后，也可以同时发生： wle引导的从句中，主句和从句的动作通常同时进行，且从句动词多为延续性动词， 常用进行时态。 真题再现（鲁教8上期末真题改编）： my father was reading a newspaper,I was watching TV. A)When B)While C)As soon as D)Until 答案：B 解析：两个延续性动作同时进行，且从句用进行时态，故用wle。 二、考点综合训练 (一)单项选择 1.We will go for a picnic if it sunny tomorrow.
