🔍 比较状语从句类型

类型①

than + 比较级

= 不同程度 —— 比什么 + 和谁比

类型②

as...as

= 同级比较 —— 一样多

用法

省略重复动词

= 省略 —— 避免啰嗦

🎯 一个是比什么,另一个是和谁比

than 表不同程度的比较,as...as 表同级比较。比较状语从句常省略重复的动词,比如 as you can 省略了 memorize,than last time 省略了 made mistakes。关键是分清比什么和和谁比。

📌 关键点

1. than 比较级

than 引导不同程度的比较,比较级用 more 或 -er。five more spelling mistakes 里 more 是比较级,表示比上次多五个。关键是分清比什么(more)和和谁比(than last time)。

2. as...as 同级比较

as...as 引导同级比较,中间放形容词或副词原级。as many words as you can 里,第一个 as 是比什么(同级),第二个 as 是和谁比(和你能记的比)。

❌ than 后重复动词

He's made five more spelling mistakes this time than last time did.

than 后省略重复的动词 made,避免啰嗦

✅ 省略重复动词

He's madefive more spelling mistakesthis timethanlast time

比较状语从句三步

1

than 引导不同程度比较

than 表不同程度的比较,这次比上次多出五个拼写错误就是不同程度。He's made five more spelling mistakes this time than last time 里,more 是比什么,than last time 是和谁比,than 后省略了重复的动词 made。 than

2

as...as 引导同级比较

同级比较用 as...as,比如 You should memorize as many words as you can。注意两个 as 一个是比什么(as many words),另一个是和谁比(as you can)。直译为:你应该记和你能记的单词一样多。 as...as

3

省略用法

as you can 其实省略了重复的动词 memorize,完整的应该是 as you can memorize。比较状语从句常省略与主句重复的部分,避免啰嗦,than last time 也省略了 made mistakes。 as you can
