形容词和副词的特殊表达法一、形容词与副词的同级比较： 由"as(so)…as"引出，其否定式为"not so…"或"not as…as",此外还应注意下列含有"as"结构或短语的句子

六、比较中的省略
1. 在as…as中，as从句可省略整个谓语部分，保留主语

5. than从句省去部分谓语，保留主语和be,have或助动词

这时 我们可以进行倒装，即将than后从句中的be,have或助动词移到该从句的前边

10. 为了避免重复，我们经常用that代替不可数名词, those代替复数名词,one代替可数名词单数
七、隐含比较级
有时比较级并不一定出现than，这时通过上下文可喑示出，如：-Of the two oranges, which do you choose? -I like the larger one.这里的larger one是指前边提到的两个当中的较大的一个。而且有些形容词在表示比较的时候，跟"to"而不用"than"
1. prior to 较早的，较重要的
