Do  做
do - did
  I will do it tomorrow.  我再明天做它。
  They did it yesterday.  他们昨天做了它。
  I did it today.  我今天做的它。
  What are you doing?  你正在做什么?
 
-
nothing
-
I'm walking the dog.
-
 没什么
-
 我正在遛狗。

最常用的询问别人正在做什么就是用do

  How are you doing?  你好吗?
 
-
good
-
 很好。

也许没有涉及完整的用法,但这就是它的使用方 法。英语同许多语 言一样有很多的表达方式,仅从句面上看不出来。Do用来表达某项活动。

  Mary does her homework every day. 玛丽每天都做家庭作业。
  John never does the dishes. 约翰从来不洗碗。

Negations  否定句

就像我们已经提到的,to be 动词不定式表 示将来时,当有用not否定的will为特征时使用。

  She isn't perfect.  她并不完美。
  They won't live here.  他们不住在这里。

许多其他的简单的现在时态在动词前面加上donot

  I don't understand Russian. 我听不懂俄语。
  Susan didn't understand. 苏珊听不懂。
  He doesn't speak Chinese. 他不说汉语。
  Don't speak to the enemy. 不要对敌人讲话。
  She doesn't talk to strangers. 她不同陌生人讲话。

Questions  疑问句

如我们已经讲过的,疑问句由to be 动词原形取代主语前面的动词。

  Is he ready?  他准备好了吗?

将来时的疑问句将will放在主语的前面来表达疑问。

  Will he be ready?  他即将准备好了吗?

把助动词do放在主语前即构成其他时态的疑问句。

  Do you speak English?  你说英语吗?
  Did they talk to you?  他们同你说话了吗?
  Does she understand?  她理解吗?
  Do you love Bart?  你爱帕特吗?
  Did he smile?  他笑了吗?

就如我们在助动词部分看到的,有一些的动词并不用这种形式来构成否定式和疑问式。
