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示两者间的比较。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
2、原级,不能修饰比较级。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
3、越美丽。3在含有or 的选择疑问句中,如果有两者供选择,前面的形容词要用比较级形式。如: Who is taller, Tim or Tom? 谁更高, Tim 还是 Tom?形容词比较级构成规律1一般情况下,比较级在后面加;如: small smaller short shorter 名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 1 页,共 9 页 - - - - - - - - - 2在重读闭音节(即:辅音元音辅音)中,先双写末尾的辅音字母,比较级加-er,如: big big
