八年级英语新目标上册unit4 知识点总结
语法归纳
形容词的比较级和最高级(二)
1. 形容词的比较级和最高级的用法
(1)形容词比较级用于两者(人或物)之间的比较,表示一方比另一方“更……”或“较……”,后面通常用比较连词than连接另一方所比较的人或物。than引导的是比较状语从句,但为了避免重复,从句中有些与主句相同的部分常常省略,而把相比较的部分省略出来。另外,在上下文明确时,形容词比较级也可以单独使用。例如:
this room is smaller八年级英语新目标上unit <wbr>4 <wbr>知识点总结辅导3 than that one (is).
这个房间比那个房间小。
he is younger than i(am).
他年纪比我小。
his english is better than his brother "s (is).
他的英语比他哥哥的好。
1. 形容词最高级用于三者或三者以上的人或事物之间的比较,表示其中一方在三者以上的人或事物中“最……”。最高级前通常用定冠词the, 并用of或in短语来说明比较的范围。of后面一般接表示同类的名词,in接表示范围的名词。例如:
he is the tallest of all.
他是所有人中最高的。
li hua is the best student in his class.
李华是他班上最好的学生。
2.比较级与最高级的区别与联系
(1)比较级是用来把彼此独立的适合人进行比较;最高级是把一个群体中的一员与整体进行比较,这个群体必须包括这个成员,请看下面例句:
(a)mary is taller than her two sisters.
玛丽比她的两个姐姐高。
(b)mary is the tallest of the girls.
玛丽是这些女孩中最高的。
【注意】句(a)中玛丽是在另外两个姐妹之外,是玛丽一个人同另外两姐妹(作为一方)来比较,所以用比较级。句(b)中玛丽是这些女孩之一,所以用最高级。
(2)比较级可以用来表示最高级的含义。例如:
jack is taller than any other stude八年级英语新目标上unit <wbr>4 <wbr>知识点总结辅导3nt/the other students in his class.(=jack is the tallest in his class.)
杰克比他班里的任何一个/其余的学生都高。(杰克是他班上最高的学生。)
any other表示“任何一个”,所以其后用单数名词,the other表示“其余的”,所以其后用名词复数。
3.比较连词than的用法
比较状语从句中的than是连词,连接的是一个句子作比较状语从句。than虽然后面常常接的是一个词,而不是句子,它仍然是连词,那是八年级英语新目标上unit <wbr>4 <wbr>知识点总结辅导3因为从句省略了系动词。
she is younger than i (am) / me.
她年纪比我小。
【注意】than后接i是省略系动词am,尤其than后面用me,这时常会使我们误认为than是介词。than后用me(宾格形式)只用于非正式文体中,表示委婉、客气的语气,比i更有礼貌,而不要把than误认为是介词。正式文体中应用i(am). [来源:学科网]
