2、f as much as last year.我们最多能完成去年工作量的一半。注:该结构中的形容词有时还可修饰另一名词,但这个名词应带有不定冠词(注意词序)。比较:She is as good a cook as her mother.= She is a cook as good as her mother.她和她妈妈一样是位好厨师。2. more and more的用法特点其意为“越来越”,其后可接修饰名词(不可数名词或复数名词均可),也可修饰形容词、副词、动词、介词短语等。如:More and more people are concerning themselves with envi
