themost--adj.用法：英語(yǔ)中三者或三者以上相比較，表示“最……”這樣的最高程度概念時(shí)，要用“the+最高級(jí)”的結(jié)構(gòu)表示。這種句式一般帶有表示比較的介詞短語(yǔ)，比如:inourclass,ofthethree等。例如：WangLinisthetallestinourclass.Thistheateristhecheapestofthethree.最高級(jí)變法有以下幾點(diǎn)：

形容詞的最高級(jí)a.直接加-est.如：short--shortestsmall--smallestb.以-e結(jié)尾的形容詞，最高級(jí)+-st。如：

large—largestnice—nicestcute—cutestc.以輔音字母+y結(jié)尾的形容詞，變y為i+est。busy—busiestheavy—heaviesteasy—easiesthappy—happiestdirty—dirtiestd.以重讀閉音節(jié)結(jié)尾，末尾只有一個(gè)輔音字母結(jié)尾的詞，雙寫最后一個(gè)輔音字母，再加+er或

+est。如：
