======================语法常识回顾=================
1.当两个动作都在过去发生，那末在有先后的情况下，第一个动作就用had+过去分词。
例如：
· The children ran away.(孩子逃走了。)
· They broke the window.(他们打碎了窗户。)
第一个动作显然先要打碎窗户，然后再逃之夭夭。所以连起来说就是：
·The children ran away after they had broken the window.
·After the children had broken the window they ran away.
例如：1)The sun set.(太阳下山了。)
2)We returned to our hotel.(我们回到旅店。)
·As soon as the sun had set we returned to our hotel.(太阳一下山，我们就回到旅店。)
2.When 有时也和过去完成式连用。
例 When he had finished lunch he asked for a glass of water.
当他吃完中午饭之后，他要讨杯水喝。(有先后动作关系)

3. 关于 not···until 句型和过去完成式的关系。
I had not understood the problem until he explained it.
(直到他解释了那个问题之后我才懂。)
这里有两个动词，一是“懂”，一是“解释”，所以有先后关系。
比较：I did not understand the problem until last night.
在这句话里面，没有先后的动词关系，所以用 did not 。

===========《 Do You Speak English？ 》============
____________________你会讲英语吗？________________
I had an amusing experience last year. After I had left a small village in the south of France, I drove on to the next town.
{ 去年，我曾有过一段好笑的经历。在我离开法国南部的一个小村庄之后，我继续开车驶向下一个城镇。}
On the way,a young man waved to me. I stopped and he asked me for a lift. As soon as he had got into the car, I said good morning to him in French and he replied in the same language. Apart from a few words, I do not know any French at all.
{在路上，一个年轻人向我招手。我停下车，他要求搭个便车。他一上车子，我就用法语向他道声早安，而他用同样的语言作了回答。除了懂仅有的几句话以外，我压根不懂什么法语。}
Neither of us spoke during the journey. I had nearly reached the town, when the young man suddenly said,very slowly,"do you speak English?" As I soon learnt,he was English himself!
{旅途中，我们双方都没有说话。我快要到达那座城镇时突然这位年青人说话了， 他说得很慢，“你会讲英语吗？”那时我马上明白过来，他本身就是英国人！}
