高考总复习 主谓一致考点透析与精炼
高考总复习: 主谓一致考点透析与精炼 审稿:张敏 责编:陈玉莲 考试要求: 主谓一致,顾名思义,就是指英语句子中的谓语动词在数、性、人称、时态等方面要和主语保持一致,这与汉语思维方式有所不同,容易被考生所忽视。高考试题在单项填空和短文改错中经常对此进行考查。 知识讲解: 主语和谓语动词在人称上的一致 当句子的主语是第一、二人称单复数及第三人称复数时,除be动词在形式上有相应的人称变化(am,are,was,were)以外,其他动词在形式上均没有数的变化 I am free on Thursday. 我星期四有空。 They are good students. 他们是好学生。 We often see her on the TV screen. 我们经常在电视上看到她。 We think it important to complete the project on time. 我们认为按时完成这项工程是很重要的。 当句子的主语是第三人称单数,除动词be和have的形式有变化(is, has)以外,其他动词在一般现在时态中均用第三人称单数形式 She is my daughter. 她是我女儿。 It's very kind of you. 你真好。 He has five dollars in his pocket. 他口袋里有五美元。 She often makes mistakes in her composition. 她经常在作文中出错。 Science requires precision while art needs imagination. 科学要求精确度而艺术则需要想象力。 值得注意的是,情态动词除了be able to以外都无人称的变化。 My daughter may watch television after supper. 我女儿晚饭后可以看电视。 We may watch television after supper. 我们晚饭后可以看电视。 主语和谓语动词在数上的一致 谓语动词用单数形式 1. 若主语是单数名词、代词、不定式及其短语、 -ing形式及其短语或从句时,谓语动词一般用单数形式。 The chief industry in the Middle East is the oil industry. 中东地区的主要工业是石油工业。 The news from the various districts is sent to a central office. 各地来的消息都送至总办公室。 That sounds a good idea. 那听起来是个好主意。 Understanding the culture habits of another nation is a complex task. 了解另一个国家的文化习俗是一项复杂的任务。 Nodding the head means agreement,while shaking it means disagreement. 点头意味着同意,摇头意味着不同意。 To hold the Olympic Games is a rich prize for a country. 举办奥运会对一个国家来说是一笔丰富的奖赏。 To learn English by recitation is a useful way. 通过背诵学习英语是一种有效的学习方法。 How you got there doesn't interest me. 你是如何到那里的我不感兴趣。 Who let out the secret is still unknown to us. 我们依然不知道是谁泄露了秘密。 What he said is not true. 他说的话不是真的。 但是,在what或whatever引导的主语从句中,主句的谓语动词的单复数形式有时还要按句子的具体意思而定。 What the children need are love and understanding. 孩子们需要的是爱和理解。 What the laser is is clear to us now. 激光是什么,现在我们清楚了。 Whatever book he praises sells well. 他表扬过的任何书都很好销。 2. 当主语是表示时间、距离、重量、货币等的复数名词时,这些名词指代的事物往往被看作是一个整体,因此谓语动词常用单数形式。 Seven feet is an abnormal height for a person. 七英尺对人来说是一个异常的高度。 Twenty miles is a long way to walk. 走20英里可是很长的一段路。 Three weeks was allowed for making the necessary preparations. 给了三个星期来作必要的准备。 Fifty kilograms is not too heavy to carry. 50公斤不至于重到扛不起来。 Thirty pounds is a high price. 30英镑价格太高了。 当然,也可以根据语法一致原则,把这些复数名词看成一个个的个体,谓语动词用复数形式。 The past four weeks have been the driest in the country's history. 过去四周是这个国家最干旱的时期。 Twenty miles were covered in half an hour. 半小时走完了20英里。 Twenty-five years have passed since we parted. 我们分别已25年了。 3. 如果主语是单数,其后跟有with,together with,as well as,no less than,but,except,like等引起的短语,谓语动词用单数。 An iron and steel works,with several satellite factories,is being built in the city. 这座城市正在修建一座钢铁厂和几家卫星工厂。 An expert,together with some assistants,was sent there to help in the work. 专家带着几个助手,被派到那里协助工作。 I as well as you am a lawyer. 不仅你是一位律师,我也是位律师。 No one but myself knows what really happened. 除了我,没有人知道发生了什么事。 Everybody except you looks down upon me. 除了你,大家都看不起我。 4. 当主语是each,either,neither或是由some,any,no,every等构成的复合代词(如someone,anybody,nothing,everything等)时,谓语动词用单数形式。 Everything goes well with me. 我一切都好。 Nothing is impossible to a willing heart. 世上无难事,只怕有心人。 Anything is better than nothing. 有总比没有好。 Is there anybody in the classroom? 教室里有人吗?

A。句意为:……几天和几周的时间是如此的渺小, 以至于一天根本微不足道。本句用来陈述事实, 用一般现在时态;空白处所在句子的主语是the time, 谓语动词应用单数形式。 2. A。根据句意, 此处应用被动语态, 不用主动语态, 故排除B;又因为when and where表示单数意义, 故排除D;再根据句末的yet可知, 最好用现在完成时, 故选A最佳。 3. D。当分数、百分数作主语时, 要根据其后面的名词来决定其谓语动词的单复数。此处one-third应 是one-third of the notebook computers的省略形式, 因此谓语动词用复数, 且句子的时态用 了过去时, 所以D项正确。 4. B。名词性从句作主语时谓语动词用单数形式。另外句中be true of意为 “对……也适应”。 5. A。由时间状语 “tomorrow afternoon”判断, 此处应用现在进行时表将来, 故排除C、D两项。 “a poet and artist”指一位诗人兼画家, 谓语动词用单数, 故选A项。 6. C。从语法讲解的角度来看, 主语The father是单数概念, 尽管后面跟有as well as his three children,谓语动词仍要用单数形式。every Sunday afternoon in winter暗示该空表示经常 性、习惯性动作, 因此应用一般现在时。从命题方式的角度看, 此题学生易弄混淆主语为his three children而出错, 在主语后添加his three children容易误导学生对主语的判断。 7. C。a number of为量词短语, 表示“许多……”, 中心词是这个短语所修饰的复数名词, 所以作主 语时, 谓语动词用复数形式。the number of表示“……的数量”, 后接复数名词, 其中, 中心 词为number, 因此谓语动词用单数。由此可以排除B;同时, “these days”表明是现在的一种 状态, 句子应为一般现在时, 因此应填keeps, 选C。如你所见, 现在路上的车子的数量不断增 加。 8. C。首先, especially those from the countryside是修饰women的, 可以把它抛开不看, 句子精简 后就是 a large number of women____(in)the clothing industry~因为a large number of是 很多的意思, 所以用动词一般现在时的复数形式。 9. B。he was used to是定语从句, 作the country life的定语。即The country life (that) he was used to has changed greatly since 1992 10. A。这个句子中, 谓语动词取决于主语No one。可把这个句子写成:No one in the department knows that the director is going to design but (=except Tom and me)。原句中的 I 正 规的语法中应该是me。这句话的意思是说, 整个部门除了我和Tom没有人知道老板要辞职的事 情。主语是“no one”所以用knows第三人称单数。 11. D。主语是all the employees(复数) , 而不是the manager, 排除答案A和C;又因all the employees与encourage是被动关系, 要用被动语态, 排除B, 故选D。 12. B。本句话的真正主语应该是the sales, 即书的销量达到50,000,000。 13. A。句子主语中有but, 需考虑就远原则, 与真正的主语No one人称一致。 14. A。首先从 主谓一致入手, one of them为单数主语, 可以先排除C和D;根据句意, “有个人受伤 了”应该是一般过去时, 因此答案为A。 15. D。定语从句先行词前有the only修饰, 从句中谓语动词只能用单数;同时, for three years. 说 明用现在完成时。 16. B。a large number of修饰可数名词, 所以先排除A的C项;desert为不可数名词, 后面的谓语动词 应该用单数has, 所以正确答案是B。 17. C。主语的means为单数名词, 意思是 “手段、方法”, 因此, 要先排除B和D项;根据句意 “所有 阻止空气污染的方法都用过了, 但天空气还是不干净。”, 可见, 此处应该用现在完成时。因 此答案应为C。 18. D。首先, 根据句意 “所有的准备工作都已经做完了, 我们准备开始做。”可见此处应该用现在完 成时;其次, preparations为复数, 即主语为复数, 所以用have, 故正确答案为D。 19. C。分数表示法:分母序数词, 分子基数词, 若分子大于一, 分母要用复数。同时, 分数修饰名词 作主语时, 谓语动词由该名词决定。“五分之二“应为”two fifths”;land是不可数名词,谓 语动词应使用单数形式。答案为C。 20. D。be surprised at为固定搭配, at不能省略, 它后面的宾语是what;what I surprised at充当 told后面宾语从句的主语, 是一个what引导的名词性句子, 后面的谓语动词应该用单数, 且和 主句用一般过去时, 从句对应也要用过去时。因此, 正确答案是D。查看更多
