2、、語(yǔ)法點(diǎn)撥1. It is + adj + of sb. + (not) to do sth.Its +adj.+of sb. to do sth.句型在英語(yǔ)中運(yùn)用較為頻繁,尤其在口語(yǔ)中。該句型通常表示說(shuō)話(huà)人對(duì)客觀事件的驚訝、興奮、懊悔、難過(guò)等感嘆情緒，其實(shí)相當(dāng)于感嘆句。如： Its very kind of you to help me. 你能幫助我，真是太好了！該句型與 how 引導(dǎo)的感嘆句可以互換,故上句可以改為: How kind it is of you to help me ! 或 How kind of you to help me ! 有時(shí)也可用簡(jiǎn)縮句型Its + adj.+

3、of sb. 或 Thats + adj. + of sb., 如: Its wrong of you . 你錯(cuò)了! Thats lovely of her. 她多可愛(ài)呀! 該句型中用作表語(yǔ)的形容詞常見(jiàn)的有如下幾類(lèi): (1) 表示聰明或愚蠢的形容詞,有clever, wise, foolish, stupid, silly等, 如: Its silly of him to do such a thing. 他竟干出這樣的事,真是愚蠢! (2) 表示正確或錯(cuò)誤的形容詞,有 right, wrong, correct, incorrect 等, 如: It was right of her not

(4) 表示褒義或貶義色彩的形容詞,有brave, polite, careless, selfish等,如: It was brave of you to manage to do it. 你居然能做成這件事,真勇敢! 【注意】Its + adj.+ for sb. to do sth.結(jié)構(gòu)是一個(gè)

5、陳述句, 表示說(shuō)話(huà)人對(duì)客觀事件的決斷, 比較正式,希望大家學(xué)習(xí)時(shí)注意。這類(lèi)形容詞有difficult, easy, hard, important, dangerous,(im)possible等。Its very dangerous for children to cross the busy street.對(duì)孩子們來(lái)說(shuō)，穿過(guò)繁忙的街道很危險(xiǎn)。 Its difficult for us to finish the work. 對(duì)我們來(lái)說(shuō)，完成這項(xiàng)工作很困難?！拘≡嚺５丁?It is impossible_me to finish the work in an hour.

6、_you to help me finish the work in an hour. 2. be + adj. + enough + to do sth.此句型表示“（某人、某物）足夠做某事”，例如： Im tall enough to reach the top of the tree. 我夠高能夠到樹(shù)頂。(1) 此句型若是肯定句時(shí)，可以用主besoadj.that的句型（即so,that表示的結(jié)果狀語(yǔ)從句）來(lái)替換。The boy is old enough to go to school. 這個(gè)孩子到了上學(xué)年齡。 =The boy is so old that he can go to

7、school. (2) 此句型若是否定句式時(shí)，既可以用sothat引導(dǎo)的結(jié)果狀語(yǔ)從句來(lái)替換，還可以用tooto句式替換。例： He is not old enough to go to work. 他太小不能去上班。 =He is so young that he cant go to work. = He is too young to go to work. The box is not light enough for me to carry. 這個(gè)箱子太重我搬不動(dòng)。 =The box is too heavy for me to carry. = The box is so heavy
