仁爱英语初二时态请帮忙总结一下初二的过去进行时的用法什么时候用,while I,什么时候用,when i.以及什么是不定代词,什么是连续性动词,什么是定语,什么是表语,并详细说明在各种情况下的用
1） 概念：表示过去某时正在进行的状态或动作.
2） 过去进行时的主要用法是描述一件事发生的背景；一个长动作发生的时候,另一个短动作发生.
3) 常用的时间状语
this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while
My brother fell while he was riding his bicycle and hurt himself.
It was raining when they left the station.
When I got to the top of the mountain, the sun was shining.
典型例题
1) Mary ___ a dress when she cut her finger.
A. made B. is making C. was making D. makes
答案C. 割伤手指是已发生的事情,应用过去时.同 时,when表时间的同时性,"玛丽在做衣服时"提供事情发生的背景,因此用过去进行时.
2) As she ___ the newspaper, Granny ___ asleep.
read； was falling B. was reading； fell C. was reading； was falling D. read；fell
答案B.句中的as = when, while,意为"当……之时".描述一件事发生的背景时,用过去进行；一个长动作发生的时候,另一个短动作发生.句意为 "在她看报纸时,奶奶睡着了."句中的 fell (fall的过去时),是系动词,后跟形容词,如：fall sick.
when和while的区别：
一.引导时间状语从句时,WHILE连接的是时间段,而WHEN连接的多是时间点
例如What does your father do while your mother is cooking?
What does your mother do when you come back?
二,WHILE可以连接两个并列的句子,而WHEN不可以
例如I was trying my best to finish my work while my sister was whtching TV
三,WHEN是特殊疑问词,对时间进行提问,WHILE不是.
例如,When were you bron?
