这道题怎么分析呢?
如果撇开复杂的语法分析,可以考虑将 as...as could be 视为习语,意思是“极其”“要……就有多……”“尽量”。如:
The room was as quiet as could be. 房间极为安静。
Both houses were as clean as could be. 两座房子都极其干净。
He lay there as still as could be. 他尽量安静地躺在那里。
She just sat there as pretty as could be. 她就坐在那儿,要多动人有多动人。
如果是现在时态,也可以用 as...as can be。如:
John is as good a creature as can be. 约翰是一个极好的人。
He is gentle and tame, and as clever as can be. 他很温和也很乖,而且极其聪明。
I can read the article as plain as can be. 我可以把这篇文章尽量读清楚。
