在英语中,谓语动词的形式需与主语的人称和数保持一致。以下是主语使用复数时谓语动词用复数的主要情况:
一、可数名词复数主语
基本规则 当主语为可数名词复数时,谓语动词需使用复数形式(如are/were或动词原形)。
- 例:
- The students are
studying for exams.
- We havefinished our homework.
特殊结构
- with连接: 谓语用单数。例如: - Tom with his friends likes
- and连接但表同一事物:谓语用单数。例如:
- The writer and singer ismy best friend.
二、不可数名词或单数名词作主语
不可数名词 谓语动词用单数形式。例如:
- The weather is
very nice today.
- The water isclean.
单数名词
谓语动词用单数形式。例如:
- The book ison the table.
- The company isexpanding rapidly.
三、特殊主语
不定代词
- each/every: 谓语用单数。例如: - Each student has
- Every day, she readstwo books.
- one of:谓语用复数。例如:
- One of the students isorganizing the event.
- either...or:谓语用单数。例如:
- Either she cansolve the problem, or he can.
集合名词 - 表示整体时用单数:
- The team is
winning the match.
- 表示个体时用复数:
- The students areparticipating in the discussion.
部分短语主语
- a number of: 谓语用复数。例如: - A number of students are
- a kind of:谓语用单数。例如:
- A kind of flower smellsvery pleasant.
四、其他注意事项
主谓一致规则:部分规则存在例外情况,需结合具体语境判断。
动词变形:复数主语需根据时态搭配动词原形(一般现在时)、过去分词(完成时)等。
通过以上规则,可确保谓语动词与主语在数上保持一致。
