when引导名词性从句时间状语从句强调时间点的使用 一、时间状语从句 连词“when”在引导时间状语从句时,主要表示某个动作或状态发生的时间。从句可以位于主句之前,也可以位于主句之后。它强调的是某个时间点或时间段。 例如:When I was young, I used to play football after school. (我小时候放学后常常踢足球。) 二、引导名词性从句 除了引导时间状语从句外,“when”还可以引导名词性从句,如主语从句、宾语从句、表语从句和同位语从句。在这种情况下,“when”不表示时间,而是表示疑问或陈述一个事实。 例如:I don't know when he will arrive. (我不知道他什么时候会到。) 三、与其他连词的区别 与“while”和“as”相比,“when”更加强调某个特定的时间点或瞬间发生的动作。而“while”和“as”则更多地表示在某个时间段内持续发生的动作。 例如:When he arrived, the meeting had already started. (当他到达时,会议已经开始了。)这里强调的是“到达”这个动作的时间点。 抗遗忘英语单词速记 随时随地背单词 不知不觉背单词 单词不用记 四、强调时间点的使用 “when”常用来强调某个特定的时间点或瞬间,它可以替换成“at the time when”或“at which time”,表示某个具体时刻发生的事情。 例如:That's when I realized my mistake. (就在那时我意识到了自己的错误。) 五、与while和as的用法对比 与“while”和“as”相比,“when”在表示时间关系时,更加灵活,可以表示短暂的时间点,也可以表示时间段。而“while”和“as”通常用来表示两个动作同时发生,且强调动作的持续性。 例如:While/As I was studying, the phone rang. (当我在学习时,电话响了。)这里强调的是学习和电话响这两个动作同时发生。 六、表示突发事件的用法 “when”还可以用来表示某个突发事件的发生,这种用法通常与“suddenly”、“suddenly”等副词连用。 例如:We were having dinner when suddenly the lights went out. (我们正在吃饭时,突然灯灭了。) 七、固定搭配和习惯用法 在英语中,“when”还有一些固定的搭配和习惯用法,如“when in Rome, do as the Romans do”(入乡随俗)、“when the cat's away, the mice will play”(猫不在,鼠称王)等。这些固定搭配和习惯用法在日常生活中非常常见,需要我们在学习和使用过程中不断积累和掌握。 填空题 1.
