3.( )at his model plane over the weekend,he didn't complete it.

Answer 1

1 选B invited 表被邀请的 句意：很遗憾,有些被邀请的人没能来参加派对.
It's a pity 很遗憾.而遗憾的事情
2 选B My parents started off at 5 o'clock, they ( should have arrived）by now.
句意：我父母早晨五点钟动身了 , 现在他们该到了. （现实是还没有到）
首先排除AD，C和B都可以用于虚拟句 表与事实相反。但是would+动词的前面要有虚拟条件句。所以选B should have+done表示本应该做，实际没有做的含义。
3 选B Hard as he worked at his model plane over the weekend,he didn't complete it.
句意：尽管他花了一整个星期为他的模型飞机刻苦钻研,他仍然没有完成
as 引导让步状语从句倒装追问

第一题D为什么不对？另外解释下什么是虚拟条件句和让步状语从句。谢谢！

追答

虚拟条件句和让步状语从句这两个知识点不是一两句能说明白的 需要你自己去找语法书好好看看，每条都有很多细节。

第一题D 不对，是因为 that some of the people 是主语(invited 定语后置 ) can not come to party是谓语部分，. 这个句子中，that some of the people 是主语，can not come to party是谓语， invited 定语后置。

如果  were invited 一看就是个谓语动词的被动式，那么can not come to party是什么成分呢？

Answer 2

1、D（过去完成时）
2、B（现在完成时）

Answer 3

三个答案都是B追答

1, 修饰the people ，作定语，与被修饰词是被动关系，＂被邀请＂，用过去分词invited 。

2，by now 到现在。should have arrived 应该已经到达。
3, Hard as he worked ＝Though he worked hard, 引起让步状语从句。汉义：虽然他十分努力做……
