常用词组 had better do sth 和 have sth to do
had better 是一个固定词组,用于表示对别人的劝告,建议或表示一种愿望。

2. 你最好安静一些
You had better be quiet
3. 你最好明天动身

4. 我们最好现在就看电视

最近被have had什么什么的弄晕了,什么时候用have done什么时候用have had有?

首先根据你的提问,我个人理解,是你对于现在完成时和过去完成时这两种语态的疑问。先明确一点,并没有had have这种使用形式。
对于现在完成时,通用的语法格式为:have/has 动词的过去分词,比如你说的done就是do的过去分词. 至于是用have还是用has这个根据主语情况进行区分,应该不需要多说了吧。
对于过去完成时,只有一种形式,had 动词的过去分词。这种情况下通用had,不需要区分主语。

had made的用法和区别?

had made的时态是:过去完成时。
had:
v.有;持有;占有;由…组成;显示出(性质、特征)
助动词.had 有时代替 if 用于从句句首,表示某种情况可能发生但并未发生
have的过去分词和过去式;
made:
v.制造;做;组装;写;出产;制订;铺床
make的过去分词和过去式。
例句:
  They had made a clear profit of 2 000.他们已赚得2000英镑的.净利。
  In general, the changes they had made were to be welcomed.总的来说,他们所作的这些变动都会被欣然接受。
  一、mαke
  1、make sb/sth do sth让…做某事 例句

  2、如果make是被动的话,结构为sb be made to do 例句:His son was made to read by him very
night.
  3、make 后可以加形容词(词组)例句: He tried to make them happy.
  4、make 后可以加名词(词组)例句: All work and no play makes Jack a dull boy.
  5、有时可以用介词短语 例句: He asked us to make ourselves at home.
  二 、have
  1、have 宾语 动词原形 /ing /过去分词 例句:
