MLA格式块引用(block quote)技巧

块引用是用来分开很大一段的引用材料，使其更容易阅读的方法。块引用要根据标准格式来用，你可以用美国现代语言协会(MLA)的风格，也可以用美国心理学协会(APA)或芝加哥格式手册的格式(CMS)。本文致远小编以MLA格式为例，教您在essay写作中如何使用块引用。

MLA格式块引用教程：

如果文本超过四行（包括四行），就用块引用。如果少于四行，就不要用，而是使用通过引号和标点符号来引用。如果你引用的是诗篇，则如果诗超过两行（不包括两行）就是用块引用。

在块引用前的引用句后加个冒号。这样表示这里是块引用，下面准备引用一段材料。

然后另起一行，开始块引用内容。这里要新建一段。

保持用双倍行距。块引用不能用单倍行距。

不要给块引用两边用引号。因为你和主文章部分分开来写，而且用的是特殊格式，所以不用再用引号了。

段落缩进1英寸（2.5厘米）。选中引用段，用工具栏的缩进工具使得引用该段落比文章其他部分缩进1英寸。

如果用的是Microsoft Word、写字板或其他文字处理软件，可以在格式下拉菜单中点击“段落”，设置左缩进为1英寸。

致远教育温馨提示：如果块引用包含超过一段以上的引用内容，每个新段落都要往内多缩进0.25英寸（0.625厘米）。

在结束的标点符号后加上括号，其中写上引用来源。这表示你的参考资料来源要在最后的句号或问号以后加上去。

下一个段落取消段落缩进。完成块引用以后，回到下拉菜单，然后点击格式-段落，然后把缩进改回0，继续写文章主部分。

扩展阅读：本科、硕士论文一般采用MLA格式。请参考MLA块引用的写作标准：

When should a block quotation be used?

When a writer chooses to include a long quotation—one that takes up four or more lines of text—it must be set off as a free standing block lxws.net. As with any quotation a writer employs as evidence, the original text should contain relevant and compelling ideas that are expressed in vivid and concise language.

Block quotations should be used sparingly in longer essays and articles (multiple pages) and rarely in shorter works (1,500 words or less). Lengthy, wordy quotations should never be used simply to fill pages when the writer has little to say about the topic or issue.

How should a block quotation be formatted?

A block quotation is introduced with an informative, full-sentence signal phrase that ends with a colon.

The entire free standing block of the quoted material is indented 1” from the left margin (10 spaces) and is double-spaced throughout.

The first line of the quotation is not indented more than the following lines, unless two or more paragraphs are quoted.

Quotation marks are not added at the beginning or end of the quotation.

The end punctuation appears at the end of the last sentence in the quotation, not after the page number; no additional punctuation appears after the parenthesis.

Example: These results deserve further investigation. (23)

Add a concluding sentence or sentences after the block quotation to complete the paragraph.

Let’s look at an example:

In their investigation of the way the human mind deals with multitasking, Salvucci and Taatgen determined that driving is an act that requires drivers to engage in a variety of simultaneous subtasks; when drivers choose to add interaction with an electronic device to an already complex activity, the new demands on their minds can distract them from their primary task:

The heavy cognitive workload of driving suggests that any secondary task has the potential to affect driver behavior. Any concurrent task would necessarily involve procedural steps and thus, whether large or small, create additional cognitive workload. At the same time, not all secondary tasks are created equal, and we would expect some tasks to interfere with driving more than others. Not surprisingly, tasks involving significant visual demand have the greatest potential for negative effects on driver performance. (108) [1]

Thus, the researchers determined that the use of electronic devices—such as cell phones—while driving can possibly place enough additional demands on the drivers’ mental capacity to compromise their ability to operate a vehicle safely.
