do的用法总结归纳小学?

do的用法总结归纳小学?

  作用一:实义do
  do作实义动词时,有do, does, did, done, doing五种形式,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!
  ④That will do.
  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 dont have any tickets for tonights concert.
  ②Kate stayed at home last night, didnt she
  ③How many books does the library have
  ④She doesnt 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. Ill 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.
  ②Dont tell a lie.
  ③He did come.
  ④-You often go to the park.
  -So we do.

小学Dont祈使句用法总结?

构成祈使句否定式的方法很简单,那就是在动词原形前加don’t——不管祈使句所用的动词为什么性质动词,情况都是一样。如:
Open the window. 把窗户打开。
→Don’t open the window. 别把窗户打开。
Come next Monday. 下周星期一来。
→Don’t come next Monday. 下周星期一别来。
1,对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。
如:
Let’s tell him the truth. 我们把实情告诉他吧。
→Let’s not tell him the truth. 我们不要把实情告诉他。
但在日常口语中,也可以把don’t放在let’s之前。
如:
Let’s don’t tell him the truth. 我们不要把实情告诉他)
2,在公共场合的提示语中,否定祈使句常用“No+名词 / V-ing形式”结构,表示“禁止做某事”。
例如:NO PHOTOS! 禁止拍照!No parking! 禁止停车!
3.祈使句的反意疑问句。
1)肯定祈使句的反意疑问句反问部分用will you 或won#39t you。
Please open the door, will/ won’t you? 请把门打开,好吗?
Be sure to write to us, will/ won’t you? 你一定要给我们写信,好吗?
2)否定祈使句的反意疑问句反问部分只用will you。
Don#39t be late again, will you? 别再迟到了,行不行?
Don’t smoke in the meeting room, will you? 不要在会议室抽烟,好吗?
3)以let#39s开头的祈使句反意疑问句反问部分用shall we。
Let#39s turn on the TV, shall we? 我们把电视打开,好吗?
以let us 开头的祈使句的反意疑问句的反问部分应为will you或won#39t you.
例如:Let us stay here, will/ won#39t you? 请(你)让我们留在这好吗?
