although、until和so that的用法 1、although引导让步状语从句的用法 although意为“尽管、虽然”，是一个连词，引导让步状语从句，强调“前后语义对立”，主句通常为转折结果。 although引导的从句可以在前，也可以在后，从句在前，通常需要用逗号和主句隔开。 Although it was raining, we went for a walk.（尽管下雨，我们还是去散步了。） We went for a walk although it was raining.（我们去散步了，尽管下雨了。） 【即讲即练】 ① ________ Mary is just a student in Grade Seven, she knows computer skills very well. A．If B．Although C．Unless 【答案】B 【详解】句意：虽然玛丽只是一名七年级的学生，但她电脑技能很好。 考查连词辨析。If如果；Although虽然；Unless除非。根据“Mary is just a student in Grade Seven”和“she knows computer skills very well”可知，前后是转折关系，用Although引导让步状语从句。故选B。 ② Many Chinese people are too shy to say “I love you” to their parents ________ they love them very much. A．although B．because C．so that D．when 【答案】A 【详解】句意：许多中国人太害羞，不敢对父母说“我爱你”，尽管他们非常爱父母。 考查连词辨析。although尽管；because因为；so that为了；when当……时。根据句意，前后两句之间“很爱父母”与“却害羞不敢说”为转折关系，应用although引导让步状语从句。故选A。 ③ ________ Zhang Guimei isn’t in good health, she works hard to help her students. A．Although B．When C．Because 【答案】A 【详解】句意：尽管张桂梅身体不好，但她仍努力工作帮助学生。 考查连词辨析。Although尽管；When当……时；Because因为。根据句意，前后两部分为转折关系，表示“虽然身体不好，但仍努力工作”，需用表示让步的连词“Although”。故选A。 ④ 虽然有些人认为明信片过时了，但我认为它们是了解不同地方的好方法。 some people think postcards are old-fashioned, I think they’re a good way to learn about different places. 【答案】Although 【详解】根据中英文提示可知，空格处表示“虽然”，although意为“虽然、尽管”，引导让步状语从句，符合语境。句首首字母大写，故填Although。 【注意】（1）although引导让步状语从句，这时主句不能再和but一起使用。 例：Although he was tired, he kept working.（正确） Although he was tired, but he kept working.（错误） （2）although和though 引导让步状语从句时通常来说可以互换，但although更正式，多用于书面语；though更口语化。 例（口语）：She’s not tall, but she’s fast, though.（她不高，但跑得快。） 在固定短语：在as though（好像）、even though（即使）中，不可用although替代though。 例：She treats me as though I were a stranger.（她待我如陌生人。） 【即讲即练】 ① ______ the ancient building is more than 500 years old, it still looks beautiful and strong. A．Because B．Unless C．Though D．If 【答案】C 【详解】句意：虽然这座古建筑已有500多年的历史，但它看起来仍然美丽而坚固。 考查连词辨析。Because因为，引导原因状语从句；Unless除非，引导条件状语从句；Though虽然，引导让步状语从句；If如果，引导条件状语从句。根据“…the ancient building is more than 500 years old, it still looks beautiful and strong.”可知，虽然这座古建筑已有500多年的历史，但它看起来仍然美丽而坚固。前后句之间存在转折或让步关系。故选C。 ② ________ it was very cold, ________ my grandfather still went swimming in Jinsha River last weekend. A．Although; but B．Although; / C．But; although D．/; although 【答案】B 【详解】句意：虽然天气很冷，但我爷爷上周末还是去金沙江游泳了。 考查连词的用法。Although尽管，虽然；but但是。although和but不能在同一个句子中同时使用；根据句意可知，前半句“天气冷”是让步条件，后半句“仍去游泳”是转折结果，应用“Although”引导让步状语从句，后半句无需再用but。故选B。 ③ Even if it’s not in the form of money, there is a hidden cost.（改为同义句，用“though”） it’s not in the form of money, there is a hidden cost. 【答案】Though 【详解】句意：即使不是金钱形式，也有隐藏成本。even if与though都可引导让步状语从句，意为“即使”，可互换。故填Though。 ④ 虽然这个爱好很难，但我发现它很有趣。 this hobby is difficult, I find it fun. 【答案】Although/Though/Even though 【详解】根据中英文对照可知，此处缺“虽然”，英语中表达“虽然”常用although、though或even though。位于句首，首字母需大写。故填Although/Though/Even though。 ⑤ 尽管你们吵架了，你们仍然是非常亲密的朋友。 you argued, you are still very close friends. 【答案】Although/Though 【详解】由汉语和英语翻译可知，空格处缺少“尽管”的英文。“although或though”意为“尽管”，句子开头，首字母大写。故填Although/Though。 ⑥ He was tired.

(合并为一句话) 【答案】Though he was tired, he still helped his neighbor carry the heavy boxes./Although he was tired, he still helped his neighbor carry the heavy boxes. 【详解】句意：他很累。他仍然帮邻居搬重箱子。原句包含两个分句“He was tired”和“He still helped his neighbor...”，二者存在转折关系，此处可以用“though/although”引导让步状语从句，表示“尽管他很累，但他还是帮邻居搬了那些沉重的箱子”，故填Though/Although he was tired, he still helped his neighbor carry the heavy boxes. 2、until的用法 （1）until意为“直到……为止”，可以作连词，也可以作介词，until后面可以引导时间状语从句，也可以接时间名词，可以在句首，也可以放后面。强调“动作一直持续到until从句表示的时间点为止”，这时主句的动词为延续性的。 I waited until he arrived.（我一直等到他来。） I slept until midnight. 我一直睡到半夜时醒了。 Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。 【即讲即练】 ① —When shall we start? —Let’s wait ________ the rain stops. A．if B．as C．until 【答案】C 【详解】句意：——我们什么时候开始？——让我们等到雨停。 考查连词辨析。if如果；as当……的时候；until直到……为止。根据“wait”可知，是“等到雨停”，用until引导时间状语从句。故选C。 ② Cook the potatoes in the pan ________ they’re soft. A．until B．when C．after D．during 【答案】A 【详解】句意：在平底锅里煮土豆，直到它们变软。 考查连词辨析。until直到……为止；when当……时候；after在……之后；during在……期间。根据语境可知，此处表达的是要一直煮土豆，直到它们变软，所以应该用until。故选A。 ③ 昨晚我直到完成作业才睡觉。 I go to bed I finished my homework last night. 【答案】 didn’t until 【详解】根据中英文对照可知，此处缺少“直到……才……”，用英文表达为not…until…；句子时态为一般过去时，go是实义动词，变否定需借助助动词did，与not缩写为didn’t，until引导时间状语从句。故填didn’t；until。 ④ 他直到老师提醒他才意识到自己的错误。 He his mistake the teacher reminded him. 【答案】 didn’t realize/realise until/till 【详解】根据中英文对照可知，此处缺少“直到……才意识到”。“意识到”的英文表达为realize/realise；“直到……才”的英文表达为not...until/till。根据语境可知句子为一般过去时，需要使用助动词did构成否定形式，realize/realise用动词原形。故填didn’t；realize/realise；until/till。 （2）until还可以用在否定句中，构成“not... until...”结构，意为“直到……才”，表示的是主句动作直到从句表示的时间点之后才开始，这时主句动词为延续性或非延续性都可以。 She didn’t leave until midnight.（她直到午夜才离开。） She didn’t arrive until 6 o’clock. 她直到6点才到。 Don’t get off the bus until it has stopped. 公共汽车停稳后再下车。 【注意】until和till的区别 在引导时间状语或从句时，通常可互相，但until可置于主句前或后，句首时需用逗号分隔，语气稍重，till通常置于主句后，较少用于句首。 例（句首）：Until he finishes work, we can’t start.（他完成工作前，我们不能开始。） 例（句尾）：She studied hard until midnight.（她努力学习到午夜。） 例（推荐）：He won’t go till tomorrow.（他明天才去。） 【即讲即练】 ① —Time to go home, Peter. —Wait a minute.

A．although B．until C．unless 【答案】B 【详解】句意：他们直到盛大的节日之前三天才完成这项艰苦的工作。 考查连词辨析。although虽然（表示让步）；until直到（表示时间，常与not连用）；unless除非（表示条件）。根据句子结构“They didn’t finish ...”，这是一个否定句，常与until搭配构成“not ... until”结构，意为“直到……才”，强调动作在盛大的节日之前三天才完成。故选B。 ③ The students didn’t leave the classroom ________ they finished all the cleaning work. A．if B．unless C．because D．until 【答案】D 【详解】句意：学生们直到完成了所有的清洁工作才离开教室。 考查连词辨析。if如果；unless除非；because因为；until直到……为止。根据“The students didn’t leave the classroom...they finished all the cleaning work.”可知，此处表示“直到……才”，用“not...until...”结构，所以此处应该用until。故选D。 ④ We will finish the work. They come back. (合并成一句) We finish the work until they back. 【答案】 won’t come 【详解】句意：我们会完成这项工作。他们会回来。合并为一句时，用“not ... until ...”结构表达“直到……才……”。原句时态为一般将来时，“will”的否定形式是“won’t”；在“until”引导的时间状语从句中，遵循“主将从现”原则，从句用一般现在时，主语they是复数，动词come用原形。故填won’t；come。 ⑤ She will leave the office when she finishes the report.(保持句子意思不变) She leave the office she finishes the report. 【答案】 won’t until 【详解】句意：她完成报告后才会离开办公室。保持句意不变需用“not...until...”结构，表示“直到…… 才……”，一般将来时的否定形式为“won’t”。故填won’t；until。 ⑥ 直到你和父母交谈，他们才会知道你的感受。 Your parents won’t know how you feel you talk to them. 【答案】until/till 【详解】根据中英文对照可知，此处缺少“直到”。“直到……才……”在英文中常用“not…until/till…”结构表达。故填until/till。 3、so that的用法 so that意为“以便，以至于”，引导目的状语从句。 so that引导的目的状语从句中多含有情态动词can/could, may/might, will/would等 He left early so that his friends wouldn't wait.（他早走是为了不让朋友等。） He spoke slowly so that we could understand.（他说得慢以便我们听懂。） She studied hard so that she could pass the exam.（她努力学习是为了通过考试。） 【即讲即练】 ① Walk closer ________ we can see the pictures clearly.
