现在进行时 – 6 与一般现在时的区别

1．一般现在时表示包括现在在内的一段时间内经常发生的动作或存在的状态；而现在进行时表示说话人说话时正在进行的动作。
试比较：     He washes his face at half past seven every day. 他每天7:30洗脸。     He is washing his face at the moment. 他这会儿正在洗脸。
    2．如果一般现在时态所表示的动作或状态带有感情色彩或强调情况的变化过程，可以用现在进行时。
如：     In spring the weather becomes warmer. 春天，天气变暖。     The wind is getting stronger and stronger. 风正变得越来越大。
        3．现在进行时也可表示现阶段正在进行的动作，但今后和以前怎样，我们不清楚；而一般现在时则强调动作的永久或长久性。
如：     He studies in No. 5 Middle School. 强调在五中读书这一事实。     He is studying in No. 5 Middle School. 强调现阶段在五中读书。

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。例如：
We are waiting for you. 我们正在等你。
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。例如：
Mr. Green is writing another novel.
他在写另一部小说。（说话时并未在写，只处于写作的状态。）
c. 表示渐变，这样的动词有：get, grow, become, turn, run, go, begin等。例如：
The leaves are turning red. 叶子在变红。
It's getting warmer and warmer. 天越来越热了。
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。例如：
You are always changing your mind. 你老是改变主意。
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.

附： Do 的四种用法

初中英语中Do 的四种用法
动词do在句中的作用可以概述为四句十二字：“做”实义，助动词，替前文，强语气。
 

作用一：实义do
do作实义动词时，有do, does, did, done, doing五形式，还有及物、不及物之分。如：
1. vt. "做；研究；整理；完成"。如：
①The old man does an hour of sport every day.
②She did her homework at home last night.
③Mother was doing the cooking when I reached home
④Have you done the exercises yet?
2. vi. "行动；工作；进展；足够"。如：
①Kate does very well in her Chinese.
②How do you do?③Well done!
 

作用二：助动do
do作助动词时，只有do, does, did三种形式，无词义，限用于含行为动词的一般现在时和一般过去时两种时态的否定句和疑问句中。如：

①They don't have any tickets for tonight's concert.
②Kate stayed at home last night, didn't she?
③How many books does the library have?
④She doesn't do the washing in the evening.
 

作用三：替代do
为避免动词的重复，使语言简练，常以do, does, did替代前文所用的行为动词。如：
①Tom runs much faster than you do.
②-Lucy, can you get some more tea, please?
-Sure. I'll do it right away.
②-Who broke the cup? -Mimi did.
③-I like bananas.
-So does he.
 

作用四：语气do
为突出感情色彩，do常用于祈使句、强调句和倒装句中，以加强语气。如：
①Do be careful. ②Don't tell a lie.③He did come.

  
过去进行时

过去进行时
指在过去的某一个时间正在发生的动作。
时间状语

at five o’clock yesterday afternoon
动词由be动词+动词ing形式构成
例句

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；一个长动作延续的时候，另一个短动作发生。
3） 常用的时间状语有this morning, the whole morning, all day yesterday,
from nine to ten last evening, when, while等。例如：My brother fell while he was riding his bicycle and hurt himself. 我兄弟骑车时摔了下来，受了伤。It was raining when they left the station. 他们离开车站时，正下着雨。
When I got to the top of the mountain, the sun was shining. 我到达山顶时，阳光灿烂。
