Unit2 Integrated skils课后巩固练习连词课件

连词 1 连词 连词是用来连接单词、短语或句子的词。 I study English and Chinses. Does he work at school or in the hospital? I get up early, but my brother gets up late. 连词是一种虚词， 它不能独立担任句子成分。用来连接词，短语，从句与句子。 连词主要可分为两类： 并列连词 从属连词 一、并列连词表示词，短语， 从句或句子之间具有并列关系。 可以表示平行关系，转折关系，选择关系和因果关系。 and (和) both … and（和,两者都） neither… nor（既不…也不…） not only… but also(不但… 而且…) as well as (和, 也, 除…外, 而且) 1.表示平行关系的连词： as well (也,而且,) 用于句末. 他是一个科学家, 而且也是一个诗人. He is a scientist, and he is a poet as well. He is a scientist as well as a poet. 他们也会来吗? Are they coming as well? This is an old clock that is not only very handsome but also accurate（精确的）． 注意： 在否定句中列举并列成份不用and，而要用or. Eg. There is no air or water there. There is no air and no water there. B. 在“祈使句+and +简单句（一般将来时）”结构中祈使句表条件，相当于if 引导的条件句。 Eg. Now stop blowing and you’ll find the glass clear again. 1）判断改错： They sat down and talk about something. They started to dance and sang. I saw two men sitting behind and ate there. 　 F F F eating sing talked 考点一：and (“和，并且”) 与 or (“否则”) “and” 连接平行结构。 （1）肯定句中用“and” 表“和”； （2）否定句中用“or”表“和” 。 2）翻译：① 我喜欢英语和数学。 ② 我不喜欢英语和数学。 I like English _____ math. I don’t like English ____ math. and or = Study hard, _____ your math will be worse. 3）用 “and” 或“or” 填空： Study hard, _____ your math will be better. and or “and”意为“这样，那么”； “or” 意为 “否则” 。 2、表示选择关系的并列连词。 常用的该类连词有：or(或则,否则) ，or else(否则) otherwise(要不然) ， either…or…(或者… 或者) 如： You should show the license right away，or you'll have to pay a fine． either A or B “或者A或者B” neither A nor B “既不A也不B” not only A but also B “不仅A而且B” --- 连词词组 ： ①Either you or I _____ going to the party.
