『壹』 五年级上册英语语法
进行时分为现在进行时过去进行时两种
现在进行时是表示现在正在发生或进行的事情:
常与这些词搭配:now,look,listen
现在进行时的结构:肯定句:I am 加 动词ing形式即现在分词
He\she\it is 加 动词ing形式即现在分词
We\They\You are 加 动词ing形式即现在分词
否定句在be动词后加not
问句把be动词提前
例如:肯定:He is singing a song.
否定:He is not singing a son.
问句:Is he singing a song?
现在进行时
现在进行时的基本用法:
a. 表示现在( 指说话人说话时) 正在发生的事情。
We are waiting for you.
b. 习惯进行:表示长期的或重复性的动作,说话时动作未必正在进行。
Mr. Green is writing another novel.
(说话时并未在写,只处于写作的状态。)
She is learning piano under Mr. Smith.
c. 表示渐变的动词有:get, grow, become, turn, run, go, begin等。
The leaves are turning red.
It's getting warmer and warmer.
d. 与always, constantly, forever 等词连用,表示反复发生的动作或持续存在的状态,往往带有说话人的主观色彩。
You are always changing your mind.
典型例题
My dictionary ___, I have looked for it everywhere but still___ it.
A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.
答案D. 前句是一个仍在持续的状态,应用进行时,由于没有找到,其影响仍然存在,应用完成时,瞬间动词用于否定式时可用于完成时。
过去进行时
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。
