形容词最高级前不加定冠词的五种情况

1.如果形容词最高级用来加强语气,表示“非常极其”的意思,前面一般不用定冠词,但有时可以用不定冠词例如 :

She was in closest touch with  us.

He is a most learned scholar in electronics.

2.作表语的形容词最高级,只用来同本身相比较,并且无一定范围时,前面不用定冠词

例如 :

The lake is deepest here. 

He is busiest on Friday.

Vegetables are best when they are fresh.蔬菜新鲜的时候最好

It is best to do so.

The stars are brightest when there is no moon.没有月亮的时候,星星最明亮

3.如果形容词最高级修饰的是同源宾语,前面不用定冠词,只用物主代词例如 :

He dreamed his most dreadful dream last night.

She smiled her sweetest smile.

He shouted his loudest shout.

Note:这种结构中的同源宾语常可省略例如 :

She sang her sweetest (song).

He ran his fastest (run).

4.如果形容词最高级用在由 that, though, as引导的倒装让步状语从句中,前面不用定冠词例如:

Youngest though he is, he is the wisest.

Most strong-bodied man as he is, he can’t move the big stone.

5.在 at (the) least, at (the) worst, at (the) best, at (the) latest, at (the) utmost, at(the) farthest等短语中,作名词用的形容词最高级前的 the常可省去例如:

He will be back on May 20 at (the) latest.

The town is 30 miles from here at (the) farthest.
