5、chever,whenever,wherever,however,no matter+疑问词引导。例如:1.as 引导让步状语从句as 引导让步状语从句,从句部分要用倒装语序。Child as he is,he can speak fluent English.尽管他是个孩子,英语却说得很棒。Much as I like it,I will not buy it.尽管我很喜欢这东西,我也不会买。2.although/though引导状语从句的 although 和 though 同义,用法基本相同。前者较正式,多置于句首; 后者较通俗,口语化,也可置于句末。例如:He didnt light
6、the fire though/although it was cold.Although he is quite old,he still jogs every day.He said he would come;he didnt,though.He didnt tell me where he had been,but I know it,though.引导倒装的让步状语从句只能用 though。Much though I love it，Ill not buy it.注意:二者皆不可与并列连词 but 连用,但可与 yet/still 连用。Though the sore be heal
7、ed,yet a scar may remain.(谚)伤口虽然愈合,但伤疤留下了。3.however/but两者都表示转折”但是”, 但词性不同。however 作此意讲是副词,故不能连接并列分句而需另起一句,且位置灵活;but 是并列连词,可以连接并列分句。The problem was difficult,however,I worked it out.I bought my sister a shirt,but she didnt like it.另外,however 还可作”无论” 解,构成”however adj./adv./状语+主语+谓语” 结构。However much he earns,he is still unsatisfied.I must catch him,however fast he runs.
