形容词,副词:比较级,最高级

(一)、形容词的比较级

1、形容词比较级在句子中的运用:两个事物或人的比较用比较级,比较级后面一般带有单词than。比较级前面可以用more, a little来修饰表示程度。than后的人称代词用主格(口语中可用宾格)。

2.形容词加er的规则:

一般在词尾加er ;

以字母e 结尾,加r ;

以一个元音字母和一个辅音字母结尾,应双写末尾的辅音字母,再加er ;

以“辅音字母+y”结尾,先把y变i,再加er 。

3.不规则形容词比较级:

good-better, beautiful-more beautiful

(二)副词的比较级

1.形容词与副词的区别(有be用形,有形用be;有动用副,有副用动)

⑴在句子中形容词一般处于名词之前或be动词之后

⑵副词在句子中最常见的是处于实义动词之后

2. 副词比较级的变化规则基本与形容词比较级相同

(不规则变化:well-better, far-farther)

四、数词:基数词、序数词

(1)1-20

one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve,thirteen,fourteen,fifteen, sixteen,seventeen,eighteen,nineteen,twenty

(2)21-99 先说“几十”,再说“几”,中间加连字符。

67→sixty-seven,78→seventy-eight,89→eighty-nine,91→ninety-one

586→five hundred and eighty-six,803→eight hundred and three

(3) l,000以上,先从右往左数,每三位数加一个“,”,

第一个“,”前为thousand,

第二个“,”前为million,

第三个“,”前为billion。

1,001→one thousand and one

18,423→eighteen thousand,four hundred and twenty-three

6,260,309→six million two hundred and sixty thousand three hundred and nine

基数词转为序数词的口诀:

基变序,有规律,词尾加上-th.

一,二,三,特殊记,词尾字母t,d,d.

八去t,九去e, ve要用f替。

ty将y变成i,th前面有个e.

若是碰到几十几,前用基来后用序。

1.at表示时间概念的某一个点。(在某时刻、时间、阶段等)。

3.There be句型

There be 句型与have, has的区别

1、There be 句型表示:在某地有某物(或人)

2、在there be 句型中,主语是单数,be 动词用is ; 主语是复数,be 动词用are ; 如有几件物品,be 动词根据最*近be 动词的那个名词决定。
