专题11 状语从句 【学习目标】 1、通过理论依据，会正确理解状语从句的连接词； 2、通过背诵该语法，会运用状语从句的不同连接词来进行填空； 3、通过大量训练，会将状语从句正确运用在篇章填空中。 【探究活动】 一、时间状语从句 1．when，while和as引导的时间状语从句 when：从句谓语动词为延续性动词或非延续性动词。从句的动作和主句的动作可以同时发生，也可以先后发生。 while：从句的谓语动词为延续性动词。从句的动作与主句的动作同时发生。 as：从句谓语一般为延续性动词。从句的动作与主句的动作同时发生或交替进行，可译为“一边……，一边……；随着……” Eg : As it gets warmer and warmer，the trees begin to come to life. 2．表示“一……就……”的连词引导的时间状语从句 (1)as soon as，the moment，the minute，the instant，immediately，directly The moment my aunt gained her diploma after four years of hard work，she was filled with joy. (2)在hardly...when...，no sooner...than...结构中，主句用过去完成时，than或when所在的从句用一般过去时。 I had hardly got to the office when my wife phoned me to go back home at once. 我刚到办公室，妻子就打电话让我回家。 3．before，since引导的时间状语从句 (1) before表示“在……之前；还未……就……；还没有来得及……就……”。 常用句式： ①It will be/was＋一段时间＋before...过了……时间才……； ②It won't be/wasn't＋一段时间＋before...没过多久就……。 We need to get to the root of the problem before we can solve it. If you miss this chance，it may be years before you get another one. (2)since意为“自从……以来” 常用句式：It is/ has been＋一段时间＋since从句(常用过去时)。 since从句的时态若是一般过去时，主句的时态常用现在完成时或现在完成进行时。 As is reported，it is over 100 years since Tsinghua University was founded. 4．till/until引导的时间状语从句 until/till用于肯定句表示“直到……为止”，其主句谓语动词必须为延续性动词；not...until/till...表示“直到……才……”，not所在的主句的谓语动词必须为非延续性动词。until可用于句首，而till不能。 If you don't understand something，you may research，study，and talk to other people until you figure it out.
