(完整版)小学英语形容词的比较级
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:①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。
②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。
③ very, quite一般只能修饰原级,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 → shorter2.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 →bigger hot →hotter3.以不发音e结尾的单音节词,比较在原级后加;如:large →larger nice →nicer4.以“辅音字母+y”结尾的双音节词,,比较级加;如:easy →easier heavy →heavier5.多数多音节词,比较级在前面加;如:beautiful → more beautiful different → more different6.有少数形容词的比较级是不规则的,必须熟记。
