但两个名 主谓一致的讲解
主谓一致是指：
1） 语法形式上要一致，即名词单复数形式与谓语要一致。
2） 意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。
一、并列结构作主语时的主谓一致 1■由and 连接主语时
And 连接的两个或多个单数可数名词、不可数名词或代词作主语时根据意义或概念确定谓 语用单数或复数
1) 并列主语表示 不同的人、物或概念时谓语动词用 复数
Li Ming and Zhang Hua are good stude nts.
Like many others, the little tramp and the naughty boy have rushed there in search of gold 小流浪汉和调皮的小男孩也赶到那里寻找金子
Both rice and wheat are grown in this area.
2) 并列主语表示同一个人、物或概念时，谓语动词用单数形式。
The professor and writer is speak ing at the meeti ng.
那位教授兼作家正在会上发言
A journ alist and authour lives on the sixth floor.
一位新闻记者兼作家
His lawyer and former college friend was with him on his trip to Europe.
他的律师兼大学时代的朋友陪他去欧洲旅行
The Premier and Foreig n Mini ster was prese nt at the state banq uet.
总理兼外长
比较：the writer and the educator have visited our school.
the writer and educator has visited our school.
His lawyer and his former college friend were with him on his trip to Europe. 注意：指同一个人或物时，并列主语前只用一个冠词，指不同的需要分别加冠词， 词具有分别的对立的意思时只需要一个冠词即可
A boy and girl are play ing tennis.
3) 并列主语前有each, every, many a , no 等修饰时谓语动词用单数
Each doctor and (each) nurse work ing in the hospital was asked to help patie nts. Every man, woma n and child is en titled to take part in the activity. 有权参力口 Every boy and (every) girl admires him for his fine sense of humour.
Many a boy and (many a ) girl has made the same mistake
No boy and no girl is there now.没有任何男孩和女孩在那里 注意：many a 跟单数可数名词但是表示复数意义翻译为很多
Many a stude nt was disappo in ted after see ing the movie.
4) 并列主语为不可分的整体时，谓语动词用单数
A law and rule about protect ing en viro nment has bee n draw n up. 关于保护环境的法律法规已经起草完成。
The knife and fork has been washed 刀叉已经被洗好
War and peace is a constant theme in history
战争与和平是历史永恒的主题 注意;常被视为主体的结构
A cup and saucer 一副杯碟
A horse and cart 马车
A knife and fork 一副刀叉
A law and rule 法规
A n eedle and thread 一套针线
Fish and chips炸鱼加炸薯条
The stars and stripes 星条旗
2. 由(either)…or或neither…nor等连接的主语时
由either…or, neither…nor, or, noton ly…but(also)…连接主语时，谓语动词陈述句中就近
原则
Either you or Jane is to be sent to New York.要么你要么简被派往纽约
Neither you nor he has finished the experiment.
Neither the teacher nor the stude nts like this piece of music. 者 E不喜欢这首曲子
Not only the old farmer but also his family were frien dly to me.

3. 主语由肯定否定两部分构成谓语跟肯定部分走
Not you but I am to an swer the questi on
I, not you, am to answer the question.
二、单一主语的主谓一致
1.名词本身自带s作主语时
1) 学科名词：physics 物理mathematics/maths 数学economics 经济学politics 政治学新闻;news
体操：Gymnastics
As we know, Physics is a fun dame ntal subject in scie nee.物理是自然科学中的一门基础学科Mathematics is a required course for middle school students.数学是中学生的一门必修课Einstein once said , “ Politics is much more difficult than physics. ” 注意：当mathematics表示运算时谓语动词用单数复数都可
If my mathematics is/are right, the answer is 56.如果我的运算正确，答案就是56

By far, three steelworks have been closed down in this city

3) 由两部分组成的物体名词作主语时，谓语动词用复数
chopsticks 筷子compasses 圆规
glasses 眼镜gloves 手套
Jea ns牛仔裤pants裤子
scissors 剪子shoes 鞋子
shorts短裤socks短袜
trousers 裤子
My trousers are white and his clothes are black.我的裤子是白色的他的衣服是黑色的
Why are your shoes so dirty?
注意;如果这些词由单位词 (a pair of, a suit of, a piece of, a kind of等)修饰时，单位词的单复数决定谓语动词的单复数
A pair of scissors is lying in that drawer.
