连字符是英语中用于连接单词或词素的标点符号,常见于复合词、前缀后缀或数字表达中。

用法要点

句型搭配

连字符常用于连接两个或多个单词形成复合形容词,修饰名词,如“well-known author”。在句子中,这些复合形容词通常放在名词前。

• a high-quality product
• a five-year-old child
• a last-minute decision

介词用法

连字符本身不直接与介词搭配,但在涉及数字、年龄或分数时,常与“to”或“between”等介词连用,表示范围,如“pages 10-15”。

• from 9-5
• ages 18-25
• between 1990-2000

语域说明

连字符在正式写作(如学术、商务文件)中需严格遵循规则,避免歧义;在非正式语境(如社交媒体)中,使用可能较灵活,但过度省略可能导致误解。

• self-esteem (formal)
• e-mail (informal variant: email)
• up-to-date information

基础例句

Please add a hyphen between 'high' and 'speed' in 'high-speed train'.

请在“高速列车”中的“high”和“speed”之间加上连字符。

My sister is a well-known artist in our town.

我姐姐是我们镇上一位知名的艺术家。

Don't forget to hyphenate 'twenty-one' when writing numbers.

写数字时,别忘了用连字符连接“二十一”。

高级例句

In academic writing, proper hyphenation ensures clarity, such as in 'post-colonial studies'.

在学术写作中,正确的连字符使用能确保清晰度,例如在“后殖民研究”中。

The contract specifies a non-disclosure agreement with hyphenated terms to avoid legal ambiguity.

合同规定了一份保密协议,其中使用连字符术语以避免法律歧义。

常见错误

❌ 错误:She is a well known singer.
✓ 正确:She is a well-known singer.

错误在于省略了连字符。当“well-known”作为复合形容词修饰名词时,必须用连字符连接,否则可能被误解为“well”和“known”分开。

❌ 错误:The event is from 10am to 2pm.
✓ 正确:The event is from 10 a.m. to 2 p.m.

错误在于使用了连字符连接时间缩写。正确用法是“a.m.”和“p.m.”之间不加连字符,用空格分隔;连字符常用于数字范围如“10-2”,但时间缩写需保持标准格式。

近义词辨析

dash

连字符(hyphen)较短,主要用于连接单词或词素(如“mother-in-law”),而破折号(dash)较长,表示停顿、解释或范围(如“1990–2000”),在印刷中通常为en dash或em dash。

Use a hyphen in 'self-confidence' but an en dash in 'pages 10–15'.

minus sign

连字符用于语言学连接,减号(minus sign)用于数学表示减法或负数,两者形状相似但功能不同;减号通常更短且上下文明确。

Hyphen: 'pre-war'; minus sign: '5 - 3 = 2'.
