(Ron 和Mom 一周前搬进新家,现在在家居店购买家具)
Ron:Come on, mom, try sitting on this sofa. It’s the most comfortable sofa I’ve ever sat on.
Mom:Wow, yes, it’s more comfortable than the old one,and it’s certainly more expensive.
Ron:How about this dining table? It’s longer than our old one.
Mom:Yes, it’s also more beautiful.
Ron:Absolutely. Mom, let’s buy both the sofa and the dining table.
Mom:Um…Wait one moment, I need to think it more carefully.
Teacher:Molly, 听完这段对话,你能猜到今天我们要学习的语法点是什么吗?
Molly:老师,这段对话出现了很多形容词和副词(comfortable, expensive,beautiful,carefully),而且主要是拿Ron家要买的新家具和以前的旧家具作对比,所以我们今天要学习的应该是形容词和副词的比较级和最高级吧。
Teacher:You are right, Molly!
Molly:但是老师,对话中出现的形容词和副词的比较级和最高级的构成和我们之前学过的不一样啊。
Teacher:是的,我们之前学的是“单音节和部分双音节形容词和副词的比较级和最高级规则变化”,今天我们要学习的是“多音节和部分双音节形容词和副词的比较级和最高级规则变化”。
Molly:好的,我知道啦。
形容词和副词比较级和最高级 多音节和部分双音节词规则变化
Teacher:Good,下面我们一起来学习吧!
1.部分双音节词和多音节形容词分别在原级前加more/most构成比较级和最高级
我们以对话中出现的多音节形容词为例,comfortable,expensive和beautiful,这三个单词的比较级和最高级为:
more comfortable most comfortable
more expensive most expensive
more beautiful most beautiful
再如: 双音节形容词famous,它的比较级和最高级为more famous most famous
Molly:我懂啦!
Teacher:Good!
2.由-ing分词和-ed分词演变过来的形容词只能加more或most构成比较级和最高级。
如:interesting,excited,tired,它们的比较级和最高级为:
more interesting most interesting
more excited most excited
more tired most tired
但是,要注意:加前缀un构成的三音节形容词不适合上述情况,仍需在其后加上er或est。
比如:
unhappy unhappier unhappiest
untidy untidier untidiest
Molly:好的,老师,对话中还出现了一个副词carefully,它的比较级也是在前面加more构成的。
Teacher:Right!
3.以形容词+ ly构成的副词要在原级前加more/most构成比较级和最高级。
如:
carefully more carefully most carefully
slowly more slowly most slowly
quickly more quickly most quickly
这里也有一个特例,即early,它既是形容词也是副词,它的比较级和最高级分别是earlier和earliest。
Molly:我记住啦!
Teacher:Well done!Don’t find excuses for failure, to find methods for success.不要为失败找借口,要为成功找方法。只有坦然接受失败,总结经验和方法才能迈向成功哦。
