中考网整理了关于中考复习知识点之时间状语从句，希望对同学们有所帮助，仅供参考。 时间状语从句 (1) 时间状语从句常用when， as， while， before， after， since， till， until，as soon as等连词来引导。 例如： It was raining hard （rain hard下大雨)when I got to school yesterday. While he was doing his homework， the telephone rang. As she walked along（沿着走)the lake， he sang happily. He had learned a little Chinese before he came to China. After he finished middle school， he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I'll ring you up as soon as I get to NewYork. I will tell him everything when he comes back. He won't believe it until he sees it with his own eyes. (3) 在带有till或until引导的时间状语从句的主从复合句里， 如果主句用肯定式， 其含义是“一直到......时，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到......才.......”“在......以前不......”，谓语动词可用瞬间动词。例如： The young man read till the light went out （熄灭) . Let's wait until the rain stops. We won't start until Bob comes. Don 't get off(从下来) until the bus stops. 【till是指直到某一特定事件发生的时候,而在那个时刻之后,该事情或状况仍将持续。Until是指直到某一特定事件发生的时候,而讲话的人在自己心里认为,在那个时刻之后,该事情或该状况将中止(不怎么可能持续)。固定组合里 from moming till night中, till/until是不能替换的.】 (责任编辑：admin) |
