He is superior to Mr Wang in mathematics.

在比较从句中为了避免重复通常用that(those)，one(ones)代替前面出现的名词。that指物，one既可指人，也可指物。that可代替可数名词单数和不可数名词，而one只能代替可数名词。例如：

The book on the table is more interesting than that on the desk.

A box made of iron is stronger than one made of wood.

表示倍数的比较级有如下几种句型:

A is three (four,etc.) times the size (height, length, width,etc) of B.

The new building is four times the size (the height) of the old one.

这座新楼是那座旧楼的四倍大(四倍高)。[高三倍]

A is three (four, etc.) times as big (high, long, wide, etc.) as B.

Asia is four times as large as Europe.亚洲是欧洲的四倍大。

A is three (four,etc.) times bigger (higher, longer, wider) than B.

例如:Your school is three times bigger than ours.

你们的学校比我们的学校大三倍。

表示两倍可以用 twice 或 double。

表示“最高程度”的形容词，如excellent，extreme，perfect等，没有最高级，也不能用比较级。

如果复数名词前有many、few，不可数名词前有much、little等表示量的形容词时，该用so而不用such。如：

I’ve had so many falls that I’m black and blue all over.

Mr White got so little money a month that he could hardly keep body and soul together.

但little不表示数量而表示“小”的意思时,仍用such。如:

They are such little children that the they cannot clean the house by themselves.

6)almost与nearly

在very, pretty, not后用nearly, 不用almost。例如：

I’m not nearly ready.

在any, no, none, never前用almost, 不用nearly。例如：

I almost never see her.

need 表示“需要”或“必须”,作情态动词时,仅用于否定句或疑问句中。在肯定句中一般用must, have to, ought to或should 代替。例如：

You needn’t come so early.

Need I finish the work today? --Yes, you must.

注意：needn’t have done“表示本来不必做某事而实际上做了某事”。例如：You needn’t have waited for me.

“should have done”表示应该做到而实际上没有做到。

You should have started earlier.

“ought to have done”表示过去应做某事而实际未做。

You ought to have helped him (but you didn’t)

书报的标题,小说等情节介绍常用一般现在时。

表示感觉,愿望和状态的某些动词如have, be, hear, see, like等词一般不用进行时。

有些动词形式上是主动结构,但表示被动的意思。常见的有可和 well, easily 等副词连用的不及物动词sell,wash,write,read,clean,cook等。例如：

The cloth washes well.这布很经洗。

The new product sells well.这新产品很畅销。

The pen writes well.这支笔很好写。

在动词 arrange,command, demand, desire,insist, order,propose, request, require, suggest等后面的宾语从句中用“(should)+ 动词原形”(虚拟语气)例如：

We suggested that we (should) have a meeting.

We insisted that they (should) go with us.
