(not “so”)3）當(dāng)同級(jí)比較的形容詞跟單數(shù)可數(shù)名詞連用時(shí)，要注意不定冠詞的位置。Eg: Exercising is as good a way as any to lose unwanted weight. (not “as a good way as”)3）在表示同級(jí)比較的 asas ;not soas 句型中，可和 just, almost, twice, three times 等詞連用，這些詞應(yīng)放在此結(jié)構(gòu)的前面。Eg: Do you regret paying fifty dollars for the dog?

(not “Mozart”)7）注意比較的排斥性，即比較對(duì)象的前后兩者不能互相包容。Eg: That kind of flower requires more frequent watering and tender care than any other in the garden. (not “any”)138）關(guān)于比較句中的替代問題A用助動(dòng)詞代替句中的有關(guān)動(dòng)詞Eg: John spends as much time watching TV as he does writing.B用代詞代替句中有關(guān)的名詞，這些代詞有 that, those, one, onesEg: Anderson has never been out of the United States, yet his accent is very similar to that of an Englishman.Eg: The novel is as interesting as the ones we have read.9）有些形容詞，由于本身的原因，不用比較級(jí)，也不能被其他程度副詞，如very 等修飾。常見的有：absolute, eternal, perfect, unique, infinite, ultimate, primaryEg: Whether you agree or not, this was the perfect arrangement for him and Paul under the circumstances. (not “most perfect”)10）和 to 連用表示比較意義的形容詞：有些形容詞，本身已是比較級(jí)的形式，后面不能用 than 應(yīng)用 to。此類詞有：prior, senior, junior, superior, inferior, preferableEg: The songs of Bob Dylan are very popular among young people, who regard him as superior to other musicians. (not “as superior to”)3、最高級(jí)的用法1）用以表示三者以上的比較Eg: The most famous observation tower in the located at the World Trade Center in New York. (not “The more famous”)2）最高級(jí)比較應(yīng)有一個(gè)范圍，這個(gè)范圍通常由所引起的前置短語或其他地點(diǎn)狀語表示。Eg: Of all brands, which do you think is the most durable?3）在最高級(jí)復(fù)數(shù)名詞結(jié)構(gòu)中，要避免最高級(jí)用比較級(jí)，或復(fù)數(shù)名詞用成單數(shù)。Eg: On the day he was to give speech, Paul was suffering from one of the worst colds he had ever had. (not “the worse colds”)4）在作表語的形容詞最高級(jí)前，若不是和別人比較，常常不加 theEg: Vegetables are best when they are fresh.4、形容詞的比較級(jí)還可用在某些固定句型中1）more and more 越來越Eg: Our country is getting stronger and stronger.2）the morethe more 越是就越Eg: Actually, the busier he is, the happier he feels.3）all the more因而更加Eg: As a result, the rich became all the richer.144）more or less 大體上，或多或少Eg: The question is more or less settled.5）more (less) than 不止，不到Eg: The lightest weighs less than 50 kilograms.He is more than a friend to me.
