Grammar 形容词
形容词是表示人或事物的性质、状态,一般置于它所修饰的名词之前作定语,或连系动词之后作表语。本单元主要讲解形容词在句中作定语,表语和用在“It is +adj.+to do sth”句型中。
一、形容词的用法
1、形容词作定语
(1)大多数形容词作定语修饰名词时,其位置在被修饰的名词前,说明名词的品质或特征。
She is a tll girl.她是一个高个子女孩。 He is a good teacher.他是一名好老师。
(2)但在下列情况下,形容词却放在它所修饰的名词之后。
a. 当被修饰的词是不定代词somebody, someone, something, anybody, anyone, anything, nobody, nothing等复合不定代词的形容词,作定语时要后置。
I would like something cheap.我想要点便宜的东西。
Is there anything new in that book 那本书里有什么新东西吗?
b. 形容词短语作定语时,要放在所修饰的名词的后面。这些形容词短语多由“形容词+介词/不定式符号”构成。
It’s a problem difficult to solve.这是个难以解决的问题。
I think he is a man suitable for the job.我认为他是个适合做这项工作的人。
(3)enough等形容词修饰名词时可前置或后置。
We have enough time/ time enough.我们有足够的时间。
(注:形/副+ enough,此时enough 必须后置)
2.形容词作表语
形容词作表语,常位于连系动词be(am, is, are), become, get, turn,look, keep, seem等词的后面,说明主语的特征、状态或身份。
The food is delicious.这种食物美味可口。 The story is very interesting.这个故事很有趣。
Gengerally speaking, it is cold in the north, it is warm in the south.
一般来说,北方天气冷,南方天气暖和。
3.句型“It is +adj.(形容词)+to do sth.(不定式短语)”
这个句型中,常用important, interesting, exciting, nice, easy, hard, good, useful, wrong, right, important等形容词。
It is dangerous to climb this hill.爬这座山很危险。
It is interesting to play in the snow.在雪里玩是有趣的。
It is important to listen to the teacher carefully in class.课堂上认真听老师讲课很重要。
a.此句型中,如果表语是kind, nice, right, wrong, clever, polite等描述性格、品质的形容词,则应在不定式前加of sb. “It is +adj. +of sb. + to do sth.”某人做某事是……
如: It is very kind of you to help me.你能帮我太好了。
It’s clever of you to do so.你这样做真聪明。
b. 如果形容词表示“对某人而言”,描述的是事情的性质,可在动词不定式前加一个for sb “It is +adj. +for sb. +to do sth.”对某人来说做某事是……
It's difficult for us to finish the work.对我们来说,完成这项工作很困难。
It’s hard for me to answer your question.对我来说,要回答你的问题很难。
二、形容词变名词的方法
1.在名词后面加-y可以变成形容词(尤其是一些与天气有关的名词)
rain—rainy多雨的,cloud—cloudy多云的,health—healthy健康的,luck—lucky幸运的
注意:①如果名词以重读闭音节结尾,且词尾只有一个辅音字母,这时应双写词尾的辅音
字母再加-y。如sun—sunny晴朗的,fog—foggy有雾的,fun—funny有趣的;
②如果以不发音的字母e结尾的名词变为形容词时,应去掉e再加y。如:
noise—noisy吵闹的, ice—icy冰冷
2.一些抽象名词在词尾加-ful可以变为形容词。
care—careful小心的,thank—thankful感谢的,help—helpful有帮助的
3.一些表示国家的名词可以在词尾加-ese, -ish或-n构成表示国籍、语言的形容词。
China—Chinese,Japan—Japanese, England—English, America—American
4.在名词后加-ous变为形容词。 danger--dangerous
5.在名词后加-ly变为形容词。 friend—friendly, love—lovely(以-ly结尾的还有lonely, lively)
6.在名词后加-less构成含有否定意义形容词。如:care—careless粗心的, use—useless无用的
7.一些以-ence结尾的名词,把-ence改为ent变成形容词。
如: difference—different不同的, silence—silent安静的
