7、le表示的是”相反的”,也可以用but, however, on the other hand来代替. While some people have nothing to eat, others eat too much.9) or连接句子或词组,表示 “或者”之意。 Which do you prefer, yellow, blue or red? Was he angry, or was he pretending?or, 也有“否则”的意思. 如:Be quick, or you will be late.10) either or/neither nor和not onlybut als

11、。 While I slept, a thief broke in.when 可以表示主句和从句先后发生. When he has finished his work, he takes a short rest. when 从句为终止动词不能用while 替换When。 he came yesterday, we were playing basketball.如从句动词为终止性动词,主句也是终止性动词 when 和as 可以互换。He came just as I reached the door.,难点链接,3) after/before After her husband died s

19、use, since , for这四个词都可表原因,但用法有区别。1) 如果原因构成句子的最主要部分,一般用because。因此,because引导的从句往往放在句末。例如:I stayed at home because it rained.-Why arent you going?-Because I dont want to.2) 如果原因已被人们所知,或不如句子的其它部分重要,就用as或since。Since比as稍微正式一点。As和since 引导的从句一般放在句子的开头。例如:As he wasnt ready, we left without him.Since I have n
