主谓一致的含义

主谓一致是指在英语句子中,主语和谓语在人称和数上要保持一致。即主语是单数形式,谓语动词也用单数形式;主语是复数形式,谓语动词则用复数形式。

主谓一致的原因

- 遵循语法规则,使句子结构正确、逻辑清晰,符合英语语言的表达习惯,让读者或听者能准确理解句子的意思。

- 有助于体现句子的主语和谓语之间的正确对应关系,避免产生歧义或误解。

- 集合名词作主语,强调个体成员时+复数谓语动词:The team are arguing about the plan.(队员们正在争论这个计划。)

- 单复数同形的名词作主语,根据意义确定谓语动词的单复数:This kind of deer is very rare.(这种鹿非常罕见。)

就近一致

- 由or, either…or…, neither…nor…, not only…but also…等连接的并列主语,谓语动词与靠近它的主语在人称和数上保持一致:Either you or he is wrong.(要么你错了,要么他错了。)

- There be句型中,be动词的单复数形式与靠近它的主语在人称和数上保持一致:There is a book and two pens on the desk.(桌子上有一本书和两支钢笔。)

- 当主语后面跟有with, together with, along with, as well as等连接的短语时,谓语动词与前面的主语在人称和数上保持一致:The teacher with his students is having a party.(老师和他的学生们正在举行聚会。)

- “half of+名词”作主语,谓语动词与of后的名词在人称和数上保持一致:Half of the apples are bad.(一半的苹果坏了。)

- “none of+名词”作主语,谓语动词的单复数形式可根据具体语境确定:None of the students is/are in the classroom.(没有一个学生在教室里。)

“none of + 名词”作主语时,谓语动词单复数形式的确定方法如下:

强调个体

当强调“none of + 名词”中的每一个个体都不具有某种特征或行为时,谓语动词通常用单数形式。例如“None of the students was late for school today.”(今天没有一个学生上学迟到。)这里着重描述的是每一个学生的到校情况,强调个体,所以用单数形式“was”。

强调整体

当强调“none of + 名词”所指代的整体概念,表示“……中没有一个”,整体上都不具备某种情况时,谓语动词通常用复数形式。例如“None of the books were interesting to him.”(这些书没有一本让他感兴趣。)此句强调的是所有书作为一个整体都不令他感兴趣,所以用复数形式“were”。

特殊情况

当“none of + 名词”作主语,且名词为不可数名词时,谓语动词通常用单数形式。例如“None of the water is left in the bottle.”(瓶子里没有水了。)

- “all of+名词”作主语,谓语动词与of后的名词在人称和数上保持一致:All of the money is mine.(所有的钱都是我的。)

- “lots of+名词”作主语,谓语动词与of后的名词在人称和数上保持一致:Lots of people are waiting for the bus.(许多人正在等公共汽车。)

- “plenty of+名词”作主语,谓语动词与of后的名词在人称和数上保持一致:Plenty of time is left.(还剩下很多时间。)
