Saddam had hardly realized what was happening when he was captured. = Hardly had Saddam realized what was happening when he was captured. 萨达姆还没有意识到在发生什么事情就被抓获了.
8、过去完成进行时

9、一般将来时
一般将来时动词表示将来发生的动作或情况.主要有以下几种表现形式：
（1）shall/will + 动词原形
表示单纯的将来,不涉及主语的主观意愿.第一人称I, we用shall 或will,其余用will. 其否定式、疑问式和简单回答形式如下：
否定式 \x09疑问式
I shall/will not study…. \x09Shall I study…?

He will not study…. \x09Will he study…?
否定疑问式 \x09简单回答（肯定/否定）

Will you not (Won’t you) study…? \x09Yes, I shall/will. No, I shan’t/won’t.
Will he not (Won’t he) study….? \x09Yes, he will. No, he won’t.
例如：
I shall be twenty years old next year. 我明年二十岁.
The sky is black. I think it will rain. 天黑下来了.我想可能会下雨.
You will meet him at the station this afternoon. 你下午会在车站碰到他.
The train will arrive soon. 火车快要到了.
When shall we see you next time? 我们下次什么时候能看见你呢?
He probably won’t go with us. 他大概不能和我们一起去.
注意：
1）shall, will的缩写形式为’ll, 如I’ll, you’ll, he’ll 和she’ll等.
2）will 用于第一人称时,可以表示将来的意愿、决心、允诺、命令等；shall用于第二、三人称时,可以表示说话人的将来的意愿.例如：

2）这种结构还可以表示说话人根据已有的迹象认为非常可能即将发生某事.例如：
Look at these black clouds?it is going to rain. 看这些乌云?要下雨了.
I think it is going to snow. 我看要下雪.
I am afraid I am going to have a bad cold. 恐怕我要得重感冒.
10、将来进行时

I will be seeing him next month. 我下个月将要见他.
Tomorrow we will be going to the village fair. 我们明天去赶集.
We will be taking our holiday at the seaside in July. 七月份我们要去海边度假.
一般将来时与将来进行时都表示将来,那么如何区别一般将来时和将来进行时呢?将来进行时不表示个人意愿,强调主观上感觉某事即将发生,并对这一事情有着期待,感情色彩较浓,强调动作.一般将来时主要是对某一事情即将发生做一个事实性的说明或陈述,强调事实或意愿.
11、过去将来时
（1）由should/would + 动词原形构成.第一人称用should; 第二、三人称用would.美国英语所有人称一律用would. should/would 的简略形式为’d, 如I’d, you’d; would not 和should not的简略形式分别为wouldn’t 和shouldn’t.
