4、级时,前后两个比较项要保持一致?若前一个比较项是不可数名词,则后一个比较项可为替代词 that?若前一个比较项是可数名词,则后一个比较项可为替代词 one, ones 或 those?此时,这些替代词是绝不可少的?例如: The books on this shelf are more interesting than the ones on that shelf. 这个书架上的书比那个书架上的书有趣? These soldiers on top of the mountain can see further than those in the wood. 山顶上这些士兵能比树林中的那些士兵看

5、得远? 另外还要注意,前后比较对象不能处于同一范围内?例如: Li Ming is cleverer than any other student in his class. 李明在他班里比任何学生都聪明? 句中的 other 不可少,因为 any student 也包括李明在内?依照常理,在同一时期或同一个方面,人或物自身不能与自身相比较?在 any 之后加上 other,就是要从 any student 中排除李明本人?如果二者不是在同一范围内,后一个比较对象就可为“any + 单数名词”?例如: Shanghai is larger than any city in Africa. 上海

6、比非洲任何一个城市都大? 二? 误用修饰语 如果句意上需要,比较级前面可以有 much, no, rather, far, a little, a lot, even, still等修饰语?例如: Be united as one, and youll win still greater victory. 团结起来,争取更大的胜利? Canada is much larger than Mexico. 加拿大的面积比墨西哥大得多? 三? 词序有误 在安排比较结构中的词序时,有些学生只考虑中文意思,却忽略了英语的习惯表达方式?例如: 1. 他比我高一头? 误:He is taller a hea

9、比较级+名词表示比较。 The taller man is the boss of the restaurant and the shorter one is his brother.那个身材较高的男人是餐馆老板。较矮的那位是他弟弟。 3. 有少数以-ior结尾的属于拉丁语的形容词，如inferior(次于), junior(年幼的;下级的), posterior(之后), prior(之前), senior(年长的,上级的), superior(优于)等本身就有比较的意思，后面不接 than，常与介系词to连用，后面用宾格。I am two years junior to you.我比你小两
