小学英语形容词的比较级

1、形容词的比较级定义：形容词是用来修饰物体的形状，大小，长度，属性，特点等，位于名词的前面。而形容词的比较级表小两者间的比较。结构：1 . “A + be +形容词比较级+ than + B ”意思为“ A比B更”如：This tree is taller than that one.这棵树比那棵树高。注意： 在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物间的比较。在比较级前面使用 much,表示程度“强得多”。如：A watermelon is much bigger than an apple.西瓜比苹果大得多。very, quite一般只能修饰原级，不能修饰比较级。

2、2 . "become +形容词比较级 + and +形容词比较级”是"变得越来越”的意思，and连接同一个形容词的比较级。如：It becomes warmer and warmer when spring comes.春天来了，天气变得越来越暖和了。注：表示“越来越”时，若比较级是“原级 + er ”构成的，则常用“比较级 + and + 比较级” 形式；若比较级是“more +原级”构成的，需用“more and more + 原级形式”。如：Our school is becoming more and more beautiful.我们的学校变得越来越美丽。3 .
