中考英語考點精講：形容詞的比較級
用法：
用于兩者(人或物)之間，表示“其中一個比另一個更……”或“較……”，后面通常用連詞than連結(jié)另一個比較的對象，其基本句型是：
主語+謂語(系動詞)+形容詞比較級+than+對比對象。
ex. Jim is taller than Mike.
Mike is shorter than Jim.
It’s hotter today than it was yesterday.
構(gòu)成：
比較級的構(gòu)成分為規(guī)則變化和不規(guī)則變化。
(一)規(guī)則變化：
1. 單音節(jié)詞尾+er：cold —colder, tall—taller, short— shorter,
small— smaller, long —longer, old— older(舊的)
2. 單音節(jié)詞以e結(jié)尾的，只加r：large— larger, fine—finer, nice— nicer.
3. 以一個元音字母加一個輔音字母結(jié)尾的重讀閉音節(jié)詞，要雙寫詞尾加er：
big—bigger, thin—thinner, hot—hotter, wet—wetter
4. 以輔音字母加y結(jié)尾的單音節(jié)詞和部分雙音節(jié)詞變比較級時，先變y為i，再加er：
early—earlier, busy—busier, easy—easier, heavy—heavier,
dry —drier, sunny—sunnier, happy—happier.
5. 多音節(jié)詞或部分雙音節(jié)詞變比較級時，在前面加more:
friendly — more friendly, careful—more careful, outgoing— more outgoing
interesting— more interesting, difficult—more difficult
6. 部分雙音節(jié)詞的比較級有兩種變化方式：
(二)不規(guī)則變化
good /well —better, bad/ill—worse, many/much—more,
old—older/elder, far—farther/further, little—less
原級和比較級前面通常使用的修飾詞：
(一)在原級前面通常使用very, quite, too, much too, a little, as, so 等。
ex: 1. The room is very big.
2. The person is quite clever.
3. Today is too hot.
4. He eats too much, so he’s much too heavy.
5. I’m a little hungry, I’d like something to eat.
6. Jim is as tall as Tom.
7. Your English is so good.
(二)在比較級前面使用的修飾詞有：even(更，更加)，a little(有點)，far/ much/ a lot (更加，……的多)
ex: 1. Yesterday was hot, but today is even hotter.
2. I’m a little taller than Mary.
3. This skirt is far/ much/ a lot more beautiful than that one.
