Question and negative forms

For example

I had been here before he came here.

I hadn’t been here before he came here.

即: had not +过去分词

slide8

Had you been here before he came here?

Yes, I had. No, I hadn’t.

即: Had +主语+过去分词?

Exercise: Part A4 Page 89

slide9

过去完成时和现在完成时的区别

现在完成时表示的动作发生在过去,但侧重对现在产生的结果或造成的影响,与现在有关,其结构为:

“have/ has + done”。

过去完成时所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某种动作作相比较时才用到它。

slide10

For example

I have learned 1000 English words so far.

I had learned 1000 English words till

then.

“I’m sorry to keep you waiting.” “Oh,

not at all. I have been here only a few

minutes. ”

(等的动作表示从过去一直持续到现在)

“Simon returned home yesterday.” “Where had he been?”

(答语中用过去完成时是指Simon在returned home 之前去了哪些地方,指的是过去的过去。)
