（支持句一）首先，许多大规模和长期的研究项目，需要投入大量资金，只有各国政府所能负担的。

连词的用法教案(一)(初中英语)
教学过程 一、复习预习 教师引导学生复习上节课所学的内容复习，（以提问、回顾的形式进行），针对上节课的作业进行讲评、订正、答疑，并通过简单的句子导入本节课所要学习的连词。 连词含义：连词是一种虚词，它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。 二、知识讲解 知识点1：并列关系连词的用法 在句子中并列连词用来连接平行的词、词组和分句。常用的并列连词有：and，both…and,not only…but also,as well as，neither…nor等。 1. 【考查点】单个连词及固定搭配的用法。 如：They sat down and talked about something. 他们坐下来并且讨论一些事情。 She plays not only the piano, but (also) the guitar. 她不仅弹钢琴而且还弹吉他。 注意：not only… but also关联两个分句时，一个分句因有否定词not 而必须倒装。 Not only does he like reading stories, but also he can even write some. 他不仅喜欢读故事书，甚至能写一些。 2.【易错点】1) 并列结构中，or通常用于否定句，and用于肯定句。
2) 但有时and也可用于否定句。请注意其不同特点： There is no air or water in the moon. 在月球上没有空气和水。 There is no air and no water on the moon. 在月球上没有空气没有水。 在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。 知识点2：表示选择关系的连词 1.【考查点】选择关系的连词及固定搭配 or意思为"或则"。either…or意思为"或者……或者……"or else/ otherwise 否则 如：Which do you prefer, tea, coffee, or juice ? 你喜欢哪一个，茶，咖啡还是果汁？ Either you or I am right. 你和我有一个是正确的。 Be silent, or else you will be kicked out. 保持沉默，否则你将会背开除。 I am tired, otherwise, I would play. 我很累，不然的话我就去玩了。 知识点3：表示转折或对比关系的连词 1.表示转折关系和对比关系的连词有but，while，yet，however等 2.【考查点】转折关系连词的用法 如：He is rich but unhappy. 他很富裕但不快乐。 Some people love cats, while others hate them. 有些人喜欢猫，而有些则讨厌他们。 She said she would be late, yet she arrived on time. 她说她将会迟到，然而他却准时到达了。 She does not like him, however, I like him. 她不喜欢他，但是我喜欢他。 They were not the bones of an animal, but (the bones) of a human being. 他们不是动物的骨头而是人类的。 注意：not 和but 后面的用词要遵循一致原则。 2.【易错点】but和however的区别。However后有逗号，but没有。 知识点4：表示因果关系的连词 1.【考查点】for因为，做并列连词使用时，是在对先行的句子补述原因或者理由， 以连接句子与句子，通常不置于句首。so, therefore 因此，then那么，因而。 如：He is absent today, for he is ill. 他今天缺席了因为他生病了。 He hurt his leg, so he couldn't play in the game. 他的腿受伤了，因此不能参加这个游戏。 知识点5：谓语动词单复数的判断 1.【考查点】句子有as well as,neither…or等连词时注意谓语动词的单复数。
