引导时间状语从句的连词 主要有 when while as by the time before after since till until as soon as 等 其中 when while 和 as 都可表示 当 时候 但用法有区别 when 意为在 时 可表示点时间或段时间 从句谓语可以是终止性动词 也可 以是延续性动词 例如 When I got home he was having supper We usually stay at home when it is raining outside 注意 注意 when 也可以作并列连词 表示一个动词正在进行的时候 突然间发生了另外一 件事 eg 用心 爱心 专心 I was fishing by the river when someone called for help 我正在河边钓鱼 就在那时有人求救 We were working in the chemistry lab when the lights went out 我们正在化学实验室工作 突然灯都熄灭了 as 意为边 边 或与 同时 重在表示两个动作同时发生 伴随进行 They sang as they danced As I was going out it began to rain while 只可表示段时间 从句谓语只限于延续性动词 例如 While I was sleeping my father came in 注 注 while 也可以作并列连词 表转折的关系 相当于 but 译为 然而 eg I like listening to music while my brother likes doing sports 我喜欢听音乐 而我的兄弟爱好运动 since 引导的时间状语从句 译为 自从 主句常用现在完成时 从句常用一 般过去时 eg We have made many dumplings since we began to cook 自从我们开始做饭起 我们已经包了许多饺子了 We haven t seen each other since we parted 我们自从分手以后一直没见过面 注 注 常用句型 It is 时间段 since 从句 译为 自从 有多长时间了 eg It is six years since she graduated from the university 自从她大学毕业已有六年的时间了 until 意为 直到 时 引导时间状语从句时 表示主句的动作发生在从句的动 作之前 当主句的谓语动词是持续性动词时 主句常用肯定形式 当主句的谓语动词是非持续 性动词时 从句常用否定形式 not until 意为 直到 才 这时的 until 可以用 before 来替换 例如 I ll stay here until you come back 我会呆在这里 直到你回来 stay 表示的动作可以持续 He didn t go to bed until he finished his homework 他直到做完作业才睡觉 go to bed 表示的动作不能持续 2 引导原因状语从句的连词 原因状语从句一般由 because since as for 引导 注意 as because since 和 for 的区别 如果原因是构成句子的最主要部分 一般用 because because 引导的从句一般不放 在句子的开头 例如 I missed the train because I got up late 注 注 对于以 why 开头的问句 一般只能用 because 引导的从句来回答 如果原因已为人们所知 或不如句子的其余部分重要 就用 as 或 since since 比 as 稍微正式一些 as 和 since 引导的从句一般放在句子的开头 例如 As he was not well I decided to go there without him Since this method doesn t work let s try another for 表示所说的理由是一种补充说明 因此 for 引导的从句可以放在括号里 而且 for 引导的从句一般不放在句子的开头 例如 用心 爱心 专心 I decided to stop and have lunch for I was feeling quite hungry 3 引导结果状语从句的连词 主要有 so such that so that 等 1 so that 结构在某种情况下可以与 enough to 和 too to 结构相互转换 例如 She is so short that she can t reach the buttons of the lift She is too short to reach the buttons of the lift 2 so that 也可以引导结果状语从句 意为 结果是 以致于 例如 They missed the bus so that they were late for class 注 注 so that 也可引导目的状语从句 此时可用 to 或 in order to 替换 将其改为简单句 例如 He got up early so that he could get to school on time He got up early to get to school on time In order to get to school on time he got up early 4 引导让步状语从句的连词 通常由 although though 等连词引导 例如 Though he is young he knows a lot Although I am tired I must go on working 注 注 although though 不能与 but 用在同一个句子中 例如 我们不能说 Though it was raining hard but he still went out 应该说 Though it was raining hard he still went out 或 It was raining hard but he still went out 典型例题典型例题 1 I m different from my twin sister I love dancing she is interested in reading A
