1、辨别形容词的方法：翻译成汉语意思后，末尾带有“的”单词就是形容词。形容词比较级的含义当我们需要对事物作出比较时，需要用到比较级。比较级的句子结构通常是： 人或物 + be 动词 (am , is , are ) + 形容词比较级+ than（比）+ 人或物 ,如： Im taller and heavier than you.（我比你更高和更重。） An elephant is bigger than a tiger.（一只大象比一只老虎更大。） 形容词比较级的变化规则1.一般在词尾加 er。 如 long 变为 longer 2.以不发音的字母 e 结尾的加 r。 如 late 变为 lat
2、er 3.呈现“辅+元+辅”结构的重读闭音节，双写末尾辅音字母再加er。 如 hot 变为 hotter 4以“辅字母+y”结尾的词先变 y 为 i 再加 er . 如 happy 变为happier形容词比较级的练习I.根据题意，写出答案。1.The black dog is _ (thin) than the white dog.2.This balloon is _ (big) than yours. 3.My bag is _ (heavy) than yours.4.John is _ (strong) than Mike. 5.
