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“越來越……”，后者表示“越……，越……”。如：
Our country is getting more and more powerful. 我們國家越來越強大。
The more we get together, the happier we will be. 人聚得越多，我們越快活。
3. more than 與less than：前者“(指數量)多于”、“不只是”、“非常”等，后者表示“少于”、“比……少”。如：
I’ve known him for more than 10 years. 我已認識他10多年了。
He is more than a father to her. 他待她勝過父親。
She was more than kind to us. 她對我們很友好。
It cost me less than 10 pounds. 我買它沒要上10英鎊。
She eats less than she should. 她吃得比她應該吃的少。
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. 他的書比我多。
He is more careful than the others. 他比其他人更仔細。
I got less money than the others did. 我比別人得到的錢少。
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. 與其說他是，不如說他是專家。
5. “no+比較級+than”結構：這類結構的實際意思是對待比較的兩個對象進行否定，相當于該原級形容詞或副詞使用as…as結構的意思。如no better than = as bad as，意為“與……一樣不好”，no faster than = as slow as，意為“與……一樣不快”，no taller than = as short as，意為“與……一樣不高”等。
6. no more than與not more than：兩者均可表示數量，前者表示“僅僅”、“只有”(= only)，強調少；而后者表示“不多于”、“至多”(= at most)。如：
It is no more than five miles to the station. 去車站只有5英里。
It is not more than five miles to the station. 去車站最多5英里。
