1.as…as 結(jié)構(gòu)。該結(jié)構(gòu)的意思是“與……一樣”,其間應(yīng)接形容詞原級(jí),不能用比較級(jí)或最高級(jí)。如:
He is as tall as his father. 他與他父親一樣高。
He is as busy as before. 他還是像以前那樣忙。
在否定句中第一個(gè)as也可換成 so,其意為“不如”:
He is not as (so) tall as his father. 他不如他父親高。
He is not as (so) busy as before. 他不像以前那樣忙。
2.more and more與the more…, the more…:前者表示“越來(lái)越……”,后者表示“越……,越……”。如:
Our country is getting more and more powerful.
我們國(guó)家越來(lái)越強(qiáng)大。
The more we get together, the happier we will be.
人聚得越多,我們?cè)娇鞓?lè)。
3.more than與less than:前者“(數(shù)量)多于”、“不只是”、“非常”等,后者表示“少于”、“比……少”。如:
Ive known him for more than 10 years. 我已認(rèn)識(shí)他10多年了。
He is more than a father to her. 他待她勝過(guò)父親。
She was more than kind to us. 她對(duì)我們很友好。
It cost me less than 10 pounds. 我買(mǎi)它花費(fèi)不足10英鎊。
She eats less than she should. 她吃得比她應(yīng)該吃的少。
4.more…than與less…than:前者表示“比……多,比……更”,后者表示“比……少,不如……”。如:
He has more books than me. 他的書(shū)比我的多。
He is more careful than the others. 他比其他人更仔細(xì)。
I got less money than the others did. 我比別人得到的錢(qián)少。
注:兩者均可表示“與其……不如”,但詞序不同。如:
He is less a teacher than an expert./He is more an expert than a teacher./He is not so much a teacher as an expert.
與其說(shuō)他是老師,不如說(shuō)他是專(zhuān)家。
5.“no+比較級(jí)+than”結(jié)構(gòu):這類(lèi)結(jié)構(gòu)的實(shí)際意思是對(duì)比較的兩個(gè)對(duì)象進(jìn)行否定,相當(dāng)于該原級(jí)形容詞或副詞使用as…as結(jié)構(gòu)的意思。如no better than=as bad as,意為“與……一樣壞”,no faster than=as slow as,意為“與……一樣慢”,no taller than=as short as,意為“與……一樣低”等。
6.no more than與not more than:兩者均可表示數(shù)量,前者表示“僅僅”、“只有”(=only),強(qiáng)調(diào)少;而后者表示“不多于”、“至多”(=at most)。如:
It is no more than five miles to the station. 去車(chē)站只有5英里。
It is not more than five miles to the station. 去車(chē)站最多5英里。
