语法一:the+最高级+比较范围
1) The Sahara is the biggest desert in the world.
形容词最高级前通常必须用定冠词 the,副词最高级前可不用。
形容词most前面没有the,不表示最高级的含义,只表示非常。
It is a most important problem.
=It is a very important problem.
注意: 使用最高级要注意将主语包括在比较范围内。
(错) Tom is the tallest of his three brothers.
(对) Tom is the tallest of the three brothers.
2) 下列词可修饰最高级,by far, far, much, mostly, almost
This hat is nearly / almost the biggest.
注意:
a. very可修饰最高级,但位置与much不同。
This is the very best.
This is much the best.
b. 序数词通常只修饰最高级。
Africa is the second largest continent.
3) 句型转换:
Mike is the most intelligent in his class.
Mike is more intelligent than any other students in his class.
4) 否定词语+比较级,否定词语+ so… as结构表示最高级含义。
Nothing is so easy as this.
=Nothing is easier than this.
=This is the easiest thing.

语法三:助动词
