1.In the first post-war local elections in northern Sri Lanka, the governing coalition has suffered a surprise defeat in Vavuniya, but it did win in Jaffna, the region's biggest city.

did强调

I do want to see him now.我现在确实很想去见他。

do是做的意思,但这里要说一下do的其它意思。上面的do是帮助构成强调句的，又例如：

Do come,please.请一定来。

I do believe you.我确实相信你。

为了构成强调 句而在动词前加do，后面的动词就只能用原形。

do做动词有做...的意思，它还可只扮演...角色。例如：

He did Hamlet in the play.他在戏里扮演哈姆雷特。

2.It was a clear summer day and it's not yet clear how the mid-air collision came about.

it形式主语

有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。这分几种情况：

(1) 对于以连词that引导的主语从句，通常用形式主语代主语从句：

It’s a pity that he didn’t come. 很遗憾他没来。

It is important that he should know about this. 他必须知道此事。

(2) 对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句：

Whether they would support us was a problem. 他们是否会支持我们还是一个问题。

It was a problem whether they would support us. 他们是否会支持我们还是一个问题。

(3) 对关系代词型what引导的主语从句，通常直接将主语从句放在句首。如：

What we need is money. 我们需要的是钱。

有时也可将助用形式主语。如：

It is clear enough what he meant. 他是什么意思很清楚。

(4) 如果句子是疑问句，则必须用带形式主语it的结构：

Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗？

How is it that you are late again? 你怎么又迟到了？
