2）有关国家和民族的形容词加上定冠词指这个民族的整体，与动词的复数连用，如the British，the English，the French，the Chinese等。例如：

常见的双音节或多音节词，在前面加more，most来构成比较级和最高级

important/ easily more important/ more easily most important/ most easily 5.as + 形容词或副词原级+as

1）在否定句或疑问句中可用so?as.例如：

He cannot run so/as fast as you. 他没你跑得快。

2）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。例如： This room is twice as big as that one. 这房间的面积是那间的两倍。 Your room is the same size as mine. 你的房间和我的一样大。 3）倍数+ as + adj. + as 倍数+ the ? + of.例如：

This bridge is three times as long as that one. 这座桥的长度是那座的三倍。 This bridge is three times the length of that one.

Your room is twice as large as mine. 你的房间是我的两倍大。 Your room is twice the size of mine.

1）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。例如：

It is a most important problem. =It is a very important problem. 这是个很重要的问题。 2）by far一般修饰最高级

学位英语语法基础知识：词法分析-连词重点用法

1.表示并列关系的连词有：and, both?and?, not only? but also?和neither?nor? 1)and的特别用法：

祈使句后连接and，有条件句作用，此时and=if you?, you'll?

Go straight on, and you'll see the library.=If you go straight on, you will see the library. 2)both?and?既?也?，（两者）都? A、both?and?谓语动词一般用复数。 Both Jim and Kate are from England. B、both?and?否定句表示部分否定。

Both my father and my mother aren't doctors.我的父母只有一个人是医生。 3)neither?nor? 既不?也不?

neither?nor?连接两个并列主语时，谓语动词靠近哪个主语就与哪个主语保持“人称”和 “数”的一致，即采取就近原则。Neither I nor he has seen the play before.

4)not only?but also? 不但?而且?

not only?but also? 连接两个主语后的谓语动词也遵循就近原则。 Not only the mother but also the children are ill.

2.表示转折关系的连词有：but, however, yet, still，while等。 Mary was a nice girl, but she had one shortcoming. Tom got up early, yet he failed to catch the train. He was very tired, still he kept on walking.

3.表示选择关系的并列连词有：or, either?or?, whether? or?等。

- 7 -

or 表示“或” 的意思，使用于两者之中选择一个的时候。 ----Is your friend English or American? ----American. He doesn't like dumplings or noodles. B:特别用法

祁使句后连接or，表 “如果?,否则?”,有转折的意思，此时 or =if you don't ?, you'll ? Hurry up, or you'll be late.=If you don't hurry up, you'll be late. 2)either?or?:或者?或者?; 不是?就是?；要么?要么?

A. either?or?连接两个并列主语时,谓语动词靠近哪个主语就与哪个主语保持 “人称”和 “数”的一致，即就近原则。

Either you or I am right. Does either she or they like English? B. 由either?or?引导的否定句是完全否定。 She isn't either a student or a teacher. 3)whether?or?不管?还是?

She is always cheerful, whether at home or at school. 4.表示因果关系的并列连词有：for（因为），so（所以）。 He is not at school today, for he has a bad cold. It was late, so I went home.

1) as 表示“当??时”，引导一个持续性动作，多用于主从句动作同时发生，强调“一边??一边”。He sang as he walked.

2)until用法：当主句谓语动词是延续性动词时，主从句都用肯定式，译为“直到??为止”；当主句谓语动词是瞬间动词时，主句用否定式，从句用肯定式，即not?until，译为“直到??才”。

Mr. Green didn't go to bed until his children came back.（格林先生直到他的孩子们回来才睡觉） 6. 引导条件状语从句的从属连词有：if（如果），unless（除非，如果??不）等。 If you don't go soon, you'll be late.=Unless you go soon, you'll be late. 7.引导原因状语从句的从属连词有because, as, since等。

- 8 -

because“因为”语气最强，回答why提问时只能用because，其引导的从句可放在句首或句末；as“由于”、since“既然”语气不如because强，引导的从句常置于句首；for是并列连词，语气最弱，对前面分句加以解释或补充说明，其引导的分句常置于句末且用逗号隔开。

He didn't go to school because he was ill. As it was raining, we went there by bus. Since everybody is here, let's begin.
