概述
Neither、Either 和 None 都用于表示“否定”或“选择”,但它们的使用场景和搭配对象不同。理解它们的区别对提高英语表达准确性至关重要。
1. Either(两者之一)
用于肯定句,表示“两个中的任意一个”。
• You can take either the red shirt or the blue one.
• Either of the answers is correct.
• Either of the answers is correct.
常见结构:
- either + 名词(单数)
- either of + 复数名词/代词
- either... or...(要么……要么……)
2. Neither(两者都不)
用于否定句,表示“两个都不”。
• Neither candidate was suitable.
• I like neither coffee nor tea.
• I like neither coffee nor tea.
常见结构:
- neither + 名词(单数)
- neither of + 复数名词/代词
- neither... nor...(既不……也不……)
注意:使用
neither of... 时,动词通常用单数(正式用法),但在口语中复数也常见。
3. None(三者或以上都不)
表示“没有一个”,可用于人或物,数量为三个或更多。
• None of the students passed the test.
• How much cake is left? — None.
• How much cake is left? — None.
常见结构:
- none of + 复数名词/不可数名词
- 回答“How many/much...?” 时可用 none
“None” 可接单数或复数动词,取决于强调的是整体还是个体。例如:
- None of the information is accurate.(不可数,单数)
- None of the books are new.(强调多本,复数)
- None of the information is accurate.(不可数,单数)
- None of the books are new.(强调多本,复数)
