什么是 both…and?
both…and 是英语中一个常用的并列结构,用于连接两个相同类型的成分(如名词、形容词、动词、从句等),表示“两者都……”。
基本结构
both + 名词/代词/形容词/动词等 + and + 名词/代词/形容词/动词等
注意:both…and 连接的两个部分在语法上必须对称。
常见用法示例
- 连接名词:Both Tom and Jerry are coming to the party.
- 连接形容词:She is both intelligent and hardworking.
- 连接动词:He both sings and dances.
- 连接从句:Both what she said and what she did surprised me.
注意事项
both…and引导的主语视为复数,谓语动词用复数形式。
例如:Both my parents are teachers.(不是 is)- 不要与
either…or或neither…nor混淆。both…and表示“两者都”,语气肯定。 - 避免重复使用
both和and之外的其他并列词,如 “both A as well as B” 是错误的。
常见错误
❌ Both he as well as she likes music.
✅ Both he and she like music.
❌ Both of them is happy.
✅ Both of them are happy.
