1.D not having…是一个省略了主语的分词结构的从句,它的主语在主句中.由于这种主从复合句不需要关联词联系,所以排除A.B两项.根据题意,是He完成不了问题,主语不应是老师,所以选D
2.C not having…跟第一题一样,主语是主句中的we,但从句中使用了完成时态的被动形式,we是被通知的对象,所以选C.
3.B the first time 前面用的是过去时was,后面就用过去完成时.意思是过去那个时候他很紧张,因为那是他到过去那时为止的第一次讲话.
4.B it做形式主语,由于真正的主语太长,所以放在后面,由it充当.That…后面的部分就是句子的真正主语.
5.A why引导的从句是用来解释说明前面reason.而is后面要接一表语从句,所以要用that 引导.
6.D 第一空是由what引导的一个主语从句,what在其中做宾语.而is后面接whether表示“能否”的意思,其余各项均不满足条件,所以选D
7.A 由why引导的表语从句.
8.B because表示事情的直接原因,在此处是“因为”的意思.
