小学英语形容词知识点及练习学习专题学习时间： 月 日 学生姓名： 效果评价： 一、 本次知识点归纳：形容词用来修饰名词或代词，表示人或事物的性质、状态和特征。它的位置通常放在被修饰的名词前，也可以放在be动词和look、feel、taste、sound、get之后。二、重要知识点提示：21、形容词比较级在句子中的运用：两个事物或人的比较用比较级，比较级后,一般带有单词than。比较级的句子结构通常是： +be 动词+ 形容词比较级 + than+ 如： Im taller than you. （我比你高。）2比较级变化规则： 一般在词尾加er talltaller. 以字母e结尾，只加r. latelater 以辅音字母y结尾，变y为i，再加er heavyheavier 以一个元音字母和一个辅音字母结尾，双写末尾的辅音字母，再加er fatfatter 不规则变化 goodbetter，bad / illworse，many / muchmore，farfarther如果比较的两者是一样的时候，我们会用 asas这个词组。+ be + as + 形容词原形 + as + ，表示“xx和xx一样”其否定形式结构为：notas原级as，表示“xx和xxx不一样”特征：asas中间一定用原形，than的前面一定要+er。 三个或三个以上的人或物进行比较，用形容词最高级。 结构为：+ be + the + 形容词最高级 in/of等表示范围的短语，表示“最”。 e.g. Autumn is the best season in New York.形容词的最高级变化类似于比较级，只是把词尾的er改成est，如：tall （原形）- taller （比较级）- tallest （最高级） 三、经典题训练过关：一、请写出下列形容词的比较级和最高级。12分big _ _ small _ _ new _ _ tall _ _ short_ _ old_ _ weak _ _strong _ _fat_ _hot _ _ cold _ _ thin _ _二.用所给词的恰当形式填空。40分1.、Sue is _(beautiful) than her sister2、My room is not as_(big)as my brothers3、-How difficult is physics? -Im not sure-Is it_(difficult)than maths? -I dont think so4、This book is not as_(interesting)as that one. 5、An orange is _(big)than an apple,but _(small) than a watermelon.6.Which is _ (big) ,the sun,the moon or the earth?7.this mooncake is _ (cheap) of all.8.He is _ (strong) in the class.9.
