语法专项突破;知识必备 ;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
