一些有两个部分构成的名词表示衣物或工具作主语时, 谓语通常用复数形式：glasses, clothes, trousers, shoes, compasses, chopsticks, scissors等。
但如果主语用a kind of , a pair of , a series of等加名词构成时, 谓语动词一般用单数形式。A pair of shoes was on the desk．
并列主语如果指的是同一个人、同一事物或同一概念时, 谓语动词用单数形式, 这时and后面的名词没有冠词。例如:
Truth and honesty is the best policy．
The girl\'s teacher and friend is a young doctor．
To love and to be loved is the great happiness.
Going to bed early and getting up early is a good habit.
A knife and fork is on the table.
当主语后面跟有as well as, as much as , no less than, along with, with, like, rather than, together with, but, except, besides, including, in addition to等引导的词组时, 其谓语动词的单、复数按主语的单、复数而定。例如:

The room with its furniture was rented．
A (great) number of修饰可数复数名词, 谓语动词用复数; a great deal of,a large amount of 修饰不可数名词, 其短语作主语时, 谓语动词用单数。

bad/ill,badly worse worst little less least
表示一方不及另一方时，用“less＋原级＋than”的结构表示：This room is less beautiful than that one．
表示一方超过另一方的程度或数量时，可在比较级前加表示程度的状语，如：even，a lot，a bit，a little，still，much，far, yet, by far等修饰：He works even harder than before．
注意:by far 通常用于强调最高级。用于比较级时,一般放在比较级的后面, 如放在前面,应在二者中间加“the”。
He is taller by far than his brother.
He is by far the taller of the two brothers.
某些以-or结尾的形容词进行比较时，用to代替than。superior，junior，senior等。
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.
