Unit6 Hitting the road

as...as/more /less … than讲解与练习

一、as … as句型（同级比较:一样/一样）

1）肯定:as + 原级 + as

含义:和……一样……结构：

主语+ be动词+ as +形容词原级+ as +比较对象

主语+动词+ as +副词原级+ as +比较对象

The trip is as exciting as I expected.这次旅行和我预想的一样令人兴奋。

Cooking hot pot is as fun as eating it.（课本原句）煮火锅和吃火锅一样有趣。

He walks as fast as his friend.他走得和他朋友一样快。

⚠️ 中间必须用原级，不能用比较级（不能说 as faster as）

 

2）否定:not as/so +原级+as

含义:不如……/没有…… /那么……

结构：

not as/so + 原级 + as（否定句里as可以换成so；肯定句只能用as）

The food is not as hot as I thought.食物没有我想的那么辣。

This road is not so wide as that one.这条路不如那条宽。

同义转换（常考）：

A is not as/so + 原级 + as B= A is 反义词比较级 + than B

This room is not as big as that one.= This room is smaller than that one.

as much + 不可数名词 + as（一样多的……）

含义：比……更……结构：

主语+ be + more +形容词原级+ than …

主语+动词+ more +副词原级+ than …

（单音节词直接加-er：hotter, faster；多音节用 more: more beautiful）

Unit6 例句：

The food was much hotter than I expected.（课本原句）食物比我预想的辣得多。

结构：

less +形容词/副词原级+ than

This problem is less difficult than that one.这道题不如那道难。

The trip is less tiring than I feared.这次旅行没有我担心的那么累。

⚠️ 注意：

less +原级 ≠ 比较级变形；less 后面永远用原级。

同义：A is less +原级+ than B = A is not as/so +原级+ as B

He is less careful than she.= He is not as careful as she.

 

三、对比总结（一眼分清）

not as/so … as	不如……	原级	not as hot as
more … than	比…… 更	原级（多音节）	more exciting than
