④when引导的状语从句中的主语与主句主语一致,主、谓是主语+系动词结构时,这时主语和系动词可以省略。例如:When (he was) young, he worked for a rich man./ Shell be here to give you help when (if it is) necessary.
⑤when有时代替if,引导条件句,意为如果、假如,例如:Ill come when (if) Im free.
2、before作连词一般表示时间,意为在之前,但有些句子中这样译就显得别扭。试看以下句子的翻译:He almost knocked me down before he saw me.他几乎把我撞倒才看见我;Before I could get in a word he had measured me.我还没来得及插话,他已经给我量好了尺寸。
3、till, until作为介词式从属连词引导时间状语短语或状语从句,用于否定句时,结构为not until (till),主句谓语动词延续与非延续皆可,意为直到才。用于肯定句时,只与延续性动词连用,表示到为止。例如:They played volleyball until (till) it got dark./ They didnt talk(延续性动词)until (till) the interpreter(译员)came./ He didnt go to bed(非延续性动词)until (till) the his father came back.;until可以放在句首,till则不行,例如:Until the last minute of the match we kept on playing./ Not until he finished his work did he go home.(倒装);till, until只用于时间,以下句子是错误的:We walked till the edge of the forest.(要用as far as或to)。
