前者强调时间概念.而后者need是情态动词,没有时态的变化.

因为是过去时,如果是现在时,才可以用needn't

前个need是实义动词,后一个是情态动词,而问句是过去时,所以只能选相应的时态。

B

Mr and Mrs Blacks构成复数概念,故应用haven’t;在完成时的否定中用yet,表示“还没、尚未”,already 用在肯定句中,表示已经。

这是主语从句,分析如下:

这是一句感叹句,其中省略了it is that,完整的句子应该是:What a shame it is that you can't come.
而其陈述句形式是:It's a shame (that) you can't come.
在陈述句中,it实际上是形式主语,真正的主语是that you can't come,正常的语序应该是:That you can't come is a shame.谓语(系动词)是is,a shame是表语.这里的That you can't come是主语从句.在It's a shame (that) you can't come.中that可以省略.
因此,What a shame you can't come中,you can't come是真正的主语(从句),a shame是表语,形式主语it和系动词is都省略了,而what只是感叹句的标志,起感叹词的作用.

宾语从句,
表语从句定义:在一个复合句中,从句作的是主语的表语成分
如He has become a teacher他已经成为一名教师
如果这句改为what i afraid is Tony.就是表语从句了.一般系动词后的从句都是表语从句,还有一些特定词如suggest、remaine、become等
