Unit 4 Growing up 知识点讲解 精选精练 2023-2024学年牛津译林版英语九年级上册 知识点讲解 1. before, after, when和while before和after既可用作介词，也可用作连词。作连词时，通常引导时间状语从句。before表示“在某个具体时间点之前”， after表示“在某个具体时间点之后”。 例如： It is our last practice before the game (starts). Simon went to play basketball after finishing / he finished his homework. when和while都作连词，可引导时间状语从句。when表示“在某个具体时间”，while表示“在某段具体时间”。例如： When the teacher came into the classroom, the students were talking about the show. The telephone rang while the Greens were having supper. 2. since, till和until since既可用作介词，也可用作连词。作连词时，通常引导时间状语从句。since表示 “从某个具体的时间开始（直到现在）”，主句通常用完成时态。例如： I haven’t had anything since 10 o’ clock. Miss Yan has worked in this school since she came to our city. till和until既可用作介词，也可用作连词。作连词时，通常引导时间状语从句。当主句是肯定句时，until表示动作的终点，主句谓语动词通常用延续性动词，意为“直到……时候， 直到……为止”。例如： I’ll wait for you here till / until lunchtime. Simon played football in the playground till / until it began to rain. 当主句是否定句时，until表示动作的起点，主句谓语动词一般用短暂性动词，not ... until意为“直到……才”。例如： Cindy didn’t realize she lost her purse until she wanted to pay for the bill. 3. as soon as和whenever as soon as可以引导时间状语从句，意为“一……就……”，表示从句的动作发生在主句之前。 例如： I will go to your office as soon as I finish writing the report. Millie called me as soon as she arrived at the train station. whenever可以引导时间状语从句，意为“无论何时”，表示从句的动作无论何时发生，主句动作随即发生。例如： He asked about my health whenever he met me. I can help you whenever you need. 精选精练 一、单项选择 1．There are mistakes in your homework. Can you find them by yourself? A．a great deal of B．much C．many D．lot of 2．He lives near the airport.
