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“AB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。 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 shorter

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 →bigger hot →hotter
3.以不发音e结尾的单音节词,比较在原级后加
如:large →larger nice →nicer
4.以“辅音字母+y”结尾的双音节词, ,比较级加 如:easy →easier heavy →heavier 5.多数多音节词,比较级在前面加
如:beautiful more beautiful different more different 6.有少数形容词的比较级是不规则的,必须熟记。
如:good/well _ bad→ _ old→ many/much→ little→ far → 专项练习:
