并列连词相当于一个“对称轴”,其两边的内容一定是对仗工整的,是平衡的。其指导意义是考生在做完形填空题时,可以根据并列连词的逻辑关系通过已知去判断未知。

【例题1】They will take home not the problems of science and technology, the benefit.

A.except B. nor C. or D. but

解析:根据空格两端内容信息判定,它们之间是转折关系,因此选D。

【例题2】Misunderstanding is oftenbutsometimes serious.

A.filling B. surprising C. anxious D. amusing

解析:通过but可以判断空的位置与已知表语形容词serious之间为转折关系,因此选D。

具体体现形式列举:

1)名词与名词并列:

Time and tide wait for no man.时不我待。

2)动词与动词并列:

He never smokes or drinks.他从不抽烟,也不喝酒。

3)形容词与形容词并列:

Tom is healthy and handsome.汤姆既健康又英俊。

4)介宾短语与介宾短语并列:

Virtue dwells not in the tongue but in the heart.看人看心不看嘴。

5)从句与从句并列:

I know that he has been arrested and that he is in prison.我知道他已经被捕并且进了监狱。

6)句子与句子并列:

She looks very young, but she is already in her 30’s.她看上去很年轻,可是她已三十多岁了。

It never rains but it pours.祸不单行。

【补充】并列连词and, but, as well as, or, or else, both…and, neither…nor, either…or, not only…but(also), rather than, as…as等以及从属连词than可连接两个对等的词和对等的结构。

1)所连接的谓语形式必须一致

【例句】He went shopping, bought some gifts and visited his old friend.

2)所连接的词或短语形式必须一致

【例句】Your success is based not only on what achievement you make, but also on what you are.

3)连接的非谓语动词的形式必须一致

【例句】People find eating vegetables more healthy than fasting.

4)所连接的句子结构必须一致

【例句】My girlfriend is pleased with what I have said and all that I have done.

英语表达中有一个不成文的原则,叫作避免重复原则。比方说在并列句中,并列连词左右两边的部分,在内容上有重复的,一般后面的部分要省略掉重复的内容。但是两边部分的内容结构一定是对称的和平衡的。今天讲的“do but do”原则就是并列句中的一种典型句式,希望对大家有帮助。
