[精华] 英文标点符号的使用 https://www.wendangku.net/doc/f916697033.html, 作者:Nicole Chan发表于：2005-11-06 01:09:30 【发表评论】【查看原文】【English Forum讨论区】【关闭】 句点（Full Stop / Period，“.”） 问号（Question Mark，“？”） 感叹号（Exclamation Mark，“!”） 逗点（Comma，“,”） 冒号（Colon，“:”） 分号（Semicolon，“;”） 连字符（Hyphen，“-”） 连接号（En Dash，“–”） 破折号（Em Dash，“—”） 括号（Parentheses，小括号“()”；中括号“[]”；大括号“{}”） 引号（Quotation Marks，双引号“"”；单引号“‘”） 缩写及所有格符号（Apostrophe，“‘”） 一、.句点 1.句点用于当一句话完全结束时。 2.句点也可以用于英文单词的缩写，如 Mrs., Dr., P.S. 等。但要注意的是当缩写的字母形成了一个单词的时候就不要使用句点。 如 IBM, DNA 等。 二、？问号 问号要用在一个直接的问句，而不是间接的。 如 How will you solve the problem？是正确的用法，但用在 I wonder how you will solve the problem？就不对了，应该使用句点而不是问号。 另外，在客气的用语中，也是用句点而不是问号. 如 Will you please give me a call tomorrow. 三、! 感叹号 感叹号用于感叹和惊叹的陈述中，在商业写作中要注意感叹号的应用，因为不恰当的使用会显得突兀及不稳重。 四、；分号 1.与中文一样，分号用于分隔地位平等的独立子句。在某些情况下，使用分号比使用句点更显出子句之间的紧密联系，另外分号也经常与连接副词 thus, however, therefore一起使用(放在这些词语之前)。 如 I realize I need exercise; however, I’ll lie down first to think about it. 2.在句子中如果已经使用过逗点，为了避免歧义的产生，就用分号来分隔相似的内容。 如 The employees were Tom Hanks, the manager; Jim White, the engineer; and Dr. Jack Lee. 需要注意的是：一个完整的句子以大写字母开始，以句点结束。写英文时用逗点代替句点、分号、冒号或破折号叫“逗号错”，这正是中国学生所要避免的。请比较下列例句：

英语中标点符号的使用方法
英语标点符号的使用——省略号和撇号 一、省略号（...） 省略号主要用两种用途： 1. 表示省略。如： Peel some oranges, bananas ...剥一些桔子、香蕉…… 2. 表示迟疑或犹豫。如： He said hesitatingly, "I ... I ... I ... don't ... like it." 他迟疑地说，“我……我……我不……喜欢它。” 二、撇号（'） 撇号主要有以下用法： 1. 表示单词中的省略。如： Don't write on the wall. 不要在墙上写字。 I've learned English for 3 years. 我已经学了三年英语。 2. 用于名词所有格。如： That is James's sister. 那是詹姆士的妹妹。 The girls' clothes are in the locker. 女孩子们的衣服在立柜里。 3. 表示数学、符号、字母或词形本身的复数。如： He got many A's during this final exam. 他在期末考试中得了很多A。 英语标点符号的使用——逗点 1. 逗点用于分隔一系列的简单内容，如：I will go to Shanghai, Beijing, and Shenzhen. 2. 逗点用于修饰名词的多个形容词之间，如：a small, fancy bike 3. 逗点用于连接两个较长的独立子句，而且每个句子的主语不同，如：The Grizzlies were out of timeouts, and Miller missed a desperation 3-pointer as time expired. 4. 逗点用于关联的子句之间，如：Since he's your younger brother, please take care of him. 5. 逗点用于一个较长的修饰短语之后，如：In the middle of the coldest winter on record, the pipes froze. 6. 逗点用于直接引用的句子之前，如Mary said, "Let's go fishing."（注意：这里说的和上面提及的冒号在直接引语中的使用不一样。如果是引用比较正式的发言讲话就要用冒号，一般情况下就用逗点。） 如果句中含有间接引用就不需要逗点，如：Mary said we should go fishing. 在反问句之前要使用逗点，如：He worked very hard, didn't he？
英语标点符号大全1
中英文标点符号的读法用法大全 ⒈ 汉语中的某些标点符号为英语所没有。 ⑴ 顿号（、）：顿号在汉语中起分割句子中的并列成分的作用；英语中没有顿号，分割句中的并列成分多用逗号。如： She slowly, carefully, deliberately moved the box. 注意：类似的情况下，最后一个逗号后可加and，这个逗号也可省略--She slowly, carefully(,) and deliberately moved the box. ⑵ 书名号（《》）：英文没有书名号，书名、报刊名用斜体或者下划线表示。如： Hamlet / Hamlet 《哈姆雷特》 Winter's Tale / Winter's Tale 《冬天的童话》 The New York Times / The New York Times 《纽约时报》 另外，英语中文章、诗歌、乐曲、电影、绘画等的名称和交通工具、航天器等的专有名词也常用斜体来表示。 ⑶ 间隔号（?）：汉语有间隔号，用在月份和日期、音译的名和姓等需要隔开的词语的正中间，如"一二?九"、"奥黛丽?赫本（人名）"等。英语中没有汉语的间隔号，需要间隔时多用逗号。 ⑷ 着重号：有时汉语用在文字下点实心圆点表示需要强调的词语，这些实心点就是着重号。而英语中没有这一符号，需强调某些成分时可借助文字斜体、某些强调性词汇、特殊句型、标点停顿等多种方法。 ⒉ 英语中的某些标点符号为汉语所没有。 ⑴ 撇号--Apostrophe（'）：该符号主要表示?所有格，如Shakespear's plays / the boy's book；?数字、符号、字母或词形本身的复数，如The teacher had only four A's in his cl ass.; ?省略了字母、数字或单词，如let's（=let us）/ I've（=I have）。 ⑵ 连字号--Hyphen（-）：该符号主要用于以下几种情况。?复合词，如world- famous。?派生词的词缀与词根或词之间，如co-worker。?两个比分、比赛对手、地名、人名、数字之间，可视情况译为"比""对""至"等。?单词移行，把在一行写不开的单词按音节移到下一行，但必须注意：a. 单音节词不移行。 b. 曲折变化后的词尾，如-er/-or/-ing等一般不移行。c. 数字、缩略词不宜移行。 d. 易引起歧义的词不移行，如legend不宜移行为leg-end。 e. 移行后行尾不宜只剩一个字母，如alone不宜移为a-lone。 f. 带词缀的词应在词缀和词根处移行，如disappear移为dis-appear。 g. 复合词在复合成分之间移行，如heartsick移为heart-sick。 ⑶ 斜线号--Virgule或Slash（/）：该符号主要起分割作用，如It could be for staff and / or students. 也常用于标音，如bed /bed/。 ⒊ 某些符号在汉英两种语言中的形式不同。 ⑴ 中文的句号是空心圈（。），英文的句号是实心点（.）。
