形容词和副词的 原级比较 初中英语语法课件 1 什么是 原级比较? 2 形容词和副词的原级比较,就是它们最基础、没有经变化的形式,也就是它们的“原形”或“原级”。 在比较两个事物或情况时,如果它们在某一方面相等或没有明显差异,我们通常会使用原级进行比较。 3 对于形容词来说,原级比较就是直接使用形容词的原形来描述两个或多个事物的状态或特征。 The apple is as big as that one. 这个苹果和那个苹果一样。 形容词“大”的原级进行比较 4 对于副词来说,原级比较也是直接使用副词的原形来描述动作或状态的方式。 He runs as fast as I do. 他跑得和我一样快。 “快”是副词的原级 5 原级比较不涉及任何形式的变化,它只是简单地陈述了两个或多个事物或动作之间的相似性。 当需要进行更具体的比较时,我们就需要使用到形容词和副词的比较级和最高级了。 tips 6 原级比较的 句子结构及用法 7 等级 原级 比较目的 比较相同水平的2个对象 结构 as+形容词/副词+as 比较对象 两个 意思 和⋯⋯一样 8 “as+形容词/副词原级+as” 表示双方在程度、特征等 方面相等。 9 He is as happy as his younger sister. 他和他妹妹一样开心。 This kind of language appeared as early as the Stone Age. 这种语言最早出现在石器时代。 10 Tom works as hard as his brother. 汤姆和他哥哥一样努力工作。 He can run as fast as you. 他能跑得和你一样快。 11 “not+as/so+形容词/副词原级+as”表示“……不如……” 12 This room is not as/so big as that one. 这个房间不如那个大。 Mary doesn’t dress so/as strangely as the other girls. 玛丽的穿着没有其他女生奇特。 13 Her mother is not as/so beautiful as before. 她的妈妈不像原来那么漂亮了。 The weather here is not as/so cool as that in Harbin. 这的天气不如哈尔滨的天气凉快。 14 如果第一个as/so后的形容词和副词作定语修饰名词,应将该名词及相关修饰语都放在第一个as/so之后。 15 We have produced as many toys as we did last year. 我们生产的玩具和去年一样多。 I don't eat as/so much fish as you do. 我吃的鱼不如你吃的多。 16 用表示倍数的词或其他程度副词做修饰语时,放在as的前面。 This box is twice as big as that one.
