一、为什么主谓一致是高一英语的「隐形失分点」
主谓一致（Subject-Verb Agreement）看起来是最小的语法点，却是听力、单选（语法填空）、完形、写作四大题型通吃的「隐形失分点」。原因很简单：中文说「我们有」「他有」，动词不变；英语里动词必须跟着主语单复数走，而高中生真正出错的地方，不是 The boy plays 这种一眼能看出的句子，而是主语后面带了一长串修饰语、主语是特殊结构、主语是集体名词的时候。
掌握一条总原则：找动词，先找它真正的主语；修饰语再长，都不影响主语的单复数。 下面把高频考点分成五类，配上例句、辨析与练习。
二、考点一：修饰语不改变主语的数
主语后面跟上 with、together with、along with、as well as、besides、except、but、including、rather than 等词引导的短语时，动词只跟最前面的主语一致。
- The teacher, together with his students, is going to the museum.（真正的主语是 The teacher）
- Nobody but Tom and Jack knows the answer.（真正的主语是 Nobody）
- The book, as well as two notebooks, was lost yesterday.
对比：如果连接词是 and 本身，那就是两个主语并列，用复数。
- The teacher and his students are going to the museum.
三、考点二：四大经典结构
1. 不定式、动名词、从句作主语 → 视为单数 - To learn a language takes patience. - Reading aloud every morning helps a lot. - What he said was very encouraging.
注意例外：what 从句作主语时，如果后面的表语是复数，动词可用复数。 - What we need are more books.
2. there be 句型 → 就近原则 - There is a pen and two books on the desk.（靠近动词的是 a pen） - There are two books and a pen on the desk.（靠近动词的是 two books）
3. either...or / neither...nor / not only...but also / or → 就近原则 - Neither you nor he is right. - Not only the students but also the teacher likes the film.
4. 主语＋with／of／分数＋of＋名词 → 与 of 后的名词一致 - Three fifths of the students are from the countryside. - 60% of the water is polluted.（water 不可数） - Half of the apple is rotten; half of the apples are rotten.——同类主语，看名词可数与否。
四、考点三：看似复数其实单数（及相反）
| 主语 | 谓语 | 例句 |
|---|---|---|
| 时间、距离、金钱、重量（作为一个整体） | 单数 | Ten years is a long time. / 500 dollars is too much. |
| 书刊、国名、学科结尾是 -s | 单数 | The United States is large. / Physics is my favourite. / The News is interesting. |
| 两部分构成的名词（glasses, trousers, shoes） | 复数 | My glasses are broken.（若说 a pair of glasses 则用单数） |
| people, police, cattle | 复数 | The police are looking for him. |
| 集体名词 family, class, team, group, public | 视意义定 | His family is a big one.（整体）／ His family are all music lovers.（强调成员） |
| each, every, either, neither, many a, more than one + 单数名词 | 单数 | Every student has a dictionary. / Many a boy likes football. |
| a number of + 复数名词 | 复数 | A number of students are absent. |
| the number of + 复数名词 | 单数 | The number of students is increasing. |
易错提醒：a number of（许多）与 the number of（……的数量）只差一个冠词，谓语却完全不同，这是高考的高频陷阱。
五、考点四：并列主语中的特殊情形
- 由 and 连接的两个主语如果指同一个人、同一件事或同一概念，用单数：The writer and poet is coming.（同一个人）
- 若指两个人，则两个名词前都有冠词：The writer and the poet are coming.
- Each...and each... / Every...and every... 作主语，用单数：Every boy and every girl has the right to education.
- 不定代词 both, few, many, several 作主语，用复数；either, neither, each, one, anybody, everything, nothing 作主语，用单数。
六、考点五：主语从句与倒装中的一致
倒装句「谓语在主语前」时，找真正的主语。 - On the wall hang two pictures.（主语是 two pictures） - Here comes the bus.（主语是 the bus） - Such were his words.（主语是 his words）
定语从句中的谓语与先行词一致。 - I, who am your friend, will help you.（先行词是 I，用 am） - Anyone who wants to join is welcome.
七、典型例题解析
例1 The number of the students in our school __ (be) about 2,000, and a number of them ____ (be) from the countryside. 解析：第一个空的主语是 The number（数量）→ 单数，填 is；第二个空是 a number of（许多）＋复数名词 → 复数，填 are。答案：is；are。
例2 Neither the driver nor the passengers ______ (injure) in the accident. 解析：neither...nor 遵循就近原则，靠近动词的是 the passengers（复数），故填 were injured。
例3 To master English, as well as other subjects, ______ (require) hard work. 解析：as well as 不改变主语的数，真正的主语是 To master English（不定式，单数），故填 requires。
例4 Every possible means ______ (try), but the result is still unclear. 解析：means 单复数同形，前面有 Every，视为单数，且「尝试」是被动的，填 has been tried。
例5 What we need most ______ (be) time and patience. 解析：what 从句作主语，后面的表语是复数 concept（time and patience），动词可用 are。
八、实用练习
- The teacher with his students ______ (be) discussing the plan.
- Either you or he ______ (have) to take charge of the task.
- Twenty miles ______ (be) a long distance for a child.
- A number of new machines ______ (have) been sent to the factory.
- Physics ______ (be) the subject I like best.
- There ______ (be) two chairs and a desk in the room.
答案：1. is；2. has（就近，主语 he）；3. is（距离作整体）；4. have；5. is（学科名）；6. are（就近，two chairs）。
九、课后作业
基础题：判断正误并说明理由。The students together with their teacher have gone to the lab.（主语是 The students，复数；together with 只作插入修饰，不改变主语的数——因此 have 是正确的。对比：The teacher together with his students has gone to the lab.） 基础题2：判断并改错。The number of the books in our library are over 100,000. → 主语是 The number（数量），单数，应把 are 改为 is。
提高题：用 a number of 与 the number of 各造两个句子，分别说明谓语的数。
挑战题：写一段 80 词左右的短文介绍你的班级，要求至少使用三种主谓一致结构（就近、就远、集体名词视义而定），并圈出谓语与主语的对应关系。
十、记忆口诀
主谓一致看主语，修饰成分不干扰； there be、就近原则要记牢； 时间金钱当整体，学科国名单数跑； family 一类看意义，a number of 用复数别弄错。
把这张规律表贴在书桌前，每次做完语法填空回头对照一遍，两周之后主谓一致就是你最稳的得分点。
