授鱼不如授渔，不如给你提供以下几条参考语法：
一、二者相比有两大类结构：
1、同级比较
as + 原级 + as （与…一样），如：
He is as tall asI (am).
He studies ashard as his classmates (does).
no + 比较级 + than （不次于…/ 与…差不多），如：
He is no tallerthan I (am). 他不比我高/他的身高和我不相上下。
He studies noharder than his classmates (does). 他学习不比同班同学努力多少。
2、差级比较
not so/as + 原级 + as （不如）。如：
He is not as tallas I (am). 他不如我高。
He doesn’t studyas hard as his classmates (does). 他学习不如同班同学努力。
比较级+ than （比…更为上/下）
He is tallerthan I (am). 他比我高。
Hestudies harderthan his classmates (does). 他学习比同班同学努力。
less + 原级 + than （比…更为下）
He is less tallthan I (am). 他不及我高。
He studies less hardthan his classmates (does). 他学习不及同班同学努力。
二、比较结构中的省略指的是与省略上文重复的所有语言信息。

补全应该是 The sick man is no better thanshe was 【省略的是与上文sickman is 重复的she was 以及与比较级意义重复的 than】
2、She's neverbetter 她现在最好不过了。
补全应该是 She's never better than shewas ever before.【省略的是与上文重复的 sheis，与 never 以及比较级意义重复的ever before 和 than】
3、Death hasnever been closer.
补全应该是death has never been closer than it has ever been
4、This couldgive her no greater pleasure.
补全应该是This could give her no greaterpleasure than that could do.【do 指代 give he】
