7、e 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
8、 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 a
9、s 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 head than I. 正:He is a head taller than I. 2. 这个房间是那个房间的两倍大。 误：his room is as twice large as that one. 正：his roo
10、m is twice as large as that one. 3. 汤姆似乎不像吉姆那样是个好孩子。 误 Tom doesnt seem to be as a good boy as Jim. 正 Tom doesnt seem to be as good a boy as Jim. 4. 她工作越努力,取得的进步就越大。 误 he harder she worked, the more she made progress. 正:The harder she worked, the more progress she made. 3四、随意省略 the。 形容词最高级前面要加定冠词 the
11、,而形容词的比较级前边通常不 加定冠词 the。如果两者进行比较,形容词比较级后面没有 than,而用 of 短语来明确说出两个比较的对象时,形容词比较级前面必须加定冠词 the。例如: 莉莉是双胞胎中较高的那个。 误: Lily is taller of the twins. 正: Lily is the taller of the twins. 1. 表示两者之中“较.” ，用 the+比较级+of the two。Ill give you the bigger of the two steaks; Im not very hungry. 我要把这块比较大的牛排给你，我不怎么饿。2. 定冠
12、词或指示形容词+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 junio
13、r to you. 我比你小两岁。该句相当于I am two years your junior. I am your junior by two years.I am two years younger than you (are).类似结构还有be senior to(年长于)+宾格 be older than+主格 be superior to(优于)+宾格 be better than+主格 be inferior to(劣于)+宾格 be worse than+主格 4. 比较形容词可以被修饰语如 a little(一点), much(得多), even(更加), still(更加), far(.得多), very much, any, no, rather, a lot (a great deal), a little (a bit)等修饰，但不可用 very 修饰，表示某种程度。 The sun is a lot bigger and brighter than the moon. 太阳比月亮大得多、亮得多。反思重建
