语法专项—形容词的比较等级(U3 U4)

英语中,为了表现不同程度的性质,大多数形容词都有三个等级,即:原级、比较级和最高级。具体来说:

1.规则变化:

大多数形容词的比较级和最高级是在词尾加-er/est;

以不发音的字母e结尾的形容词直接在词尾加-r/st;

以“辅音字母+y”结尾的形容词,变y为i,再 加-er/est;

以重读闭音节的单个辅音字母结尾的形容词,双写辅音字母,再加-er/est;

多音节和部分双音节形容词在其前面加more/most。

2.不规则变化:

原级 比较级 最高级

good better best

bad worse worst

little less least

much/many more most

far farther/further farthest/furthest

old older/elder oldest/eldest

3.比较等级中的典型句型

(1) 两者程度相同的比较

①as+ adj.原级+as …和…一样…

他和Mike一样高。He is _______ _______ ______ Mike.

②not as……as或者not so ……as 不及……

他没有Mike高。He is _______ _____ ________ _________ Mike.

若第一个as后的adj.作定语修饰n.,应将该n.及有关修饰语都放在第一个as之后。如:

My sister doesn’t make as much money as my brother does.

(2) 高于或低于另一方的比较

最基础的用法是A+ 比较级+than +B。如:

她比我大。She is _________ ________ me .

如果要表达更具体的比较,如:她比我大3岁,可以在形容词比较级前面加上具体的数。She is 3 years older than me

另外还有表示大几倍的,同样是在形容词的比较级前加上具体的倍数。例如: 他的房间比我的大两倍。His room is bigger than mine.

→His room is three times bigger than mine.

(3) “越来越……”

①单音节的就用“比较级+比较级”

越来越高 __________ ________ _________

越来越大 __________ _________ _________

②多音节的就用more and more +多音节的形容词

越来越漂亮_________________________________

越来越流行_______________________________________

(4) the+比较级……,the +比较级…… “某人越……,(就)会越……”

越多,越好。The _________, the _________.

你吃的越多,你就会越胖。

The ______ you eat ,________ __________ you will be.

你锻炼的越多,你就会越健康。

____________________,_______________________________.

你锻炼的越少,你就会越不健康。___________________,______________________________.

比较级的修饰语有

much, even 甚至, (by) far 大大地, a little 有点, a bit 有点, still, yet, a lot 很, a great deal 大大地, twice, five times, many times, two-fifths, 20%

4. 最高级的用法

(1) 最高级是表示在三者或更多者中程度最高的比较方式。运用adj.的最高级,

句式为:

the+ adj.最高级+n.+表示范围的短语或从句 (in/of+范围)

Lucy is _______________________ girl______ her class.

Lucy是 班里最漂亮的女孩。

Jim is __________________ boy _______the three students

Jim是这三个学生中中最瘦的男孩。

特别注意:

介词in和of引导的短语用于比较结构时所表达的范围有所不同: 如果在一定的地域空间内进行比较用in

如果是在同一类事物范围内进行比较用of

(2) “最……”的其他表达方法

① 运用比较级表达最高级概念

Ann is taller than any other girl in her class.

Ann is taller than the other girls in her class.

Ann is taller than the rest of girl in her class.

② 否定句中用“a/an+比较级”表示最高级概念

I have never read a better book than this.

最高级的修饰语有:序数词,(by)far,nearly 几乎,almost 几乎 Africa is the second largest continent.

Of all the students, Amy’s writing is almost the best.

Yaoming is by far the most active member in their team.

(3)表达“最??之一” one of +形容词的最高级+名词的复数形式 鲁迅是最伟大的作家之一。

Luxun is ________ _____ _______ _________ ___________.

5.常用句型:①A+be+比较级+than+B;
