*40.All the children had been waiting on the square for as l

由于非常渴望见到自己崇拜的偶像,所有的孩子在广场持续等待,长达三小时.前面是一个完整的句子,有自己的主语谓语宾语地点状语和时间状语,后面其实是一个作原因状语的短语,表示主句发生的原因.
1.首先排除的是A和D,因为后面see用的是动词原形,而look forward to 和be devoted to 后面必须跟动词ing形式,因为这里的to是介词,而非不定式,前者表示“盼望……”,后者表示“热衷于……”.
2.其次,排除的是C,因为exciting表示“令人兴奋的”,它的逻辑主语必须是物,而原句中,逻辑主语是all the children,是人.
3.be dying to do something,是一固定用法,表示“非常渴望做某事,很想做某事”.类似用法还有be longing for sth,be starving to do sth,意思同be dying to do sth 一样.
4.正确表述：1.All the children had been waiting on the square for as long as three hours, devoted或者looking forward to seeing their pop stars.
2.All the children had been waiting on the square for as long as three hours, excited to see their pop stars.
