I found the book interesting.
某些形容词与定冠词连用表示一类人作主语时，谓语通常用复数形式。如：

The English like to be with their families.
多个形容词作定语修饰名词的顺序：

2、 形容词比较等级的形式
(1) 规则形式
一般说来，单音节词及少数双音节词在后加-er; --est 来构成比较级和最高级；其他双音节词及多音节词在前加more, most.如：
great-greater-greatest
busy-busier-busiest
important-more important-(the)most important
(2) 不规则形式
good (well)-better-best
bad (ill)-worse-worst
many (much)-more-most
little-less-least
(3) 形容词比较等级的用法
①表示两者的比较，用形容词的比较级+than. 如：

This one is more beautiful than that one.
②表示两者以上的比较，用"the +形容词最高级(+名词)+of(in) …"如：
He is the cleverest boy in his class.
③表示两者是同等程度，用"as +形容词原级+as". 如：
He is as tall as I.
I have as many books as you.
④ 越… 越…
例如：The more I learn, the happier I am.
⑤ You can never be too careful. 越小心越好
又如：You can never praise the teacher too highly.

⑥ I have never spent a more worrying day.

hardly意为"几乎"与hard在词义上完全不同。如：

初二英语上册语法归纳 篇六
感叹句的类型：
⑴ What a∕an+adj+可数名词单数 （+主语+谓语）！
What +adj+可数名词复数∕不可数名词 （+主语+谓语）！

②He is a clever boy.
一判：boy为名词；二定：boy为名词，用What来引导；三移：把He is移到What a clever boy 后面，即为感叹句What a clever boy he is!
③He studies English well.
一判：well为副词；二定：well为副词，用How 来引导；三移：把He studies移到How well后面，即为感叹句How well he studies!
