13、smuchstrongerthanyou.最高级后的介词in与of. a. in 表示“在内(指某范围内)” 可以跟表示单位,组织,时间等单数名词. b. of表示属性(指在同类的人,物中)后可接the +基数词 / the +基数词+名词复数 / all +the +复数名词/all形容词的最高级前要用the，但是当形容词最高级前有物主代词，指示代词，名词所有格修饰时，不再加the.比较级前不加the.但当特指两者中“较(更)”时，比较级前通常要带定冠词the 。Marywasthemorebeautifulofthetwo.玛丽是这两个人当中较美丽的。Thisdictionaryisthe

14、moreusefulofthetwo.在这两本词典中，这本更有用。 针对练习：改错：1. His computer is cheaper than I.2. Mary is very younger than her brother.3. Shanghai is bigger than any city in China.4.
