【步步登高】2014年高考英语总复习专项专题课件：并列连词和状语从句（37ppt，含2013试题）[来源：学优高考网1162240].pptVIP

语法专项突破 1．并列连词归纳 2.使用时特别注意其连词特性 (1)and，not only...but (also)．..，neither，nor，neither...nor...等词连接的并列句，在意义上主要对前一句子作补充或引申，包括肯定和否定两方面的意义。如： Think it over，and youll find a way out. 仔细考虑，你将发现一条出路。 Neither does he work hard，nor does his brother. 他和他兄弟工作都不努力。 (2)or, either...or...连接并列句表示选择意义。如： The children can go with us，or they can stay in.(选择) 孩子们可以跟我们一起去，也可以留下。 Be careful，or you will break your neck.(否定条件) 小心点，否则你会折断脖子的。 二、状语从句 状语从句在主从复合句中修饰主句中的动词、形容词或副词等，按意义可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。 1．时间状语从句 通常由从属连词when，whenever，as，while，before，after，as soon as，till(until)，since，once(一旦)等引导。如： Please dont talk so loud while others are working. 别人工作时，请不要大声说话。 Once you understand the rules of the game，youll enjoy it. 一旦你理解了游戏规则，你就会享受到它的乐趣。 as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner...than...和hardly/scarcely...when...(一……就……) 这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”。从句中用一般时态代替将来时态。如： The moment I heard the voice, I knew father was coming. 我一听到那个声音，我就知道父亲来了。 No sooner had we arrived at the station that the train left. 我们一到车站，火车就离站了。 The boy burst into tears immediately he saw his mother. 那男孩一见到妈妈便放声大哭。 注意：no sooner...than...和hardly/scarcely...when...的时态搭配：no sooner与hardly/scarcely引导的句子的谓语动词应用过去完成时，而than与when引导的句子的谓语动词应用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，应用倒装语序。如： Ihad hardly got home when it began to rain. Hardly had I got home when it began to rain. 我一到家就下起雨来。 2．地点状语从句 通常由连词where和wherever引导，从句可位于主句之前，也可位于主句之后。如： Make a mark where you have any questions. 在你有问题的地方作个标记。 3．原因状语从句 通常由because，since，as，now that，seeing (that)，considering that等引导。如： Seeing that its raining，wed better stay indoors. 既然下雨，我们最好待在室内。 Now that you have grown up，you must do it by yourself. 既然你已经长大了，就必须自己做这件事。 Considering that I have told you three times，you must know it. 鉴于我已经告诉你三次，你必须知道它。 4．目的状语从句 目的状语从句通常由that，so that，in order that，so，for fear that，in case等引导。如： The teacher must speak clearly so that his students can understand well. 老师必须讲话清楚，学生才能理解
