Essay写作中使用逗号的六种情况

不知道同学们去国外留学了一段时间后有没有发现，国外大学平时的Essay写作比国内的写作要严格得多，非常注重细节。如果细节出错的话，扣分非常严重。而Essay写作中最能体现细节的就是标点符号的使用了，下面就给大家分析一下Essay写作中使用逗号的几种情况。

Essay写作中，逗号被用来分隔分句和短语。由于国内传统英语写作教学中没有对标点进行系统的指导，导致很多留学生在去到国外学习完成Essay的时候使用标点时「随性而为」,「凭感觉」做判断，例如：

Demand for irrigation water is mainly influenced by climate change, the scale and patterns of crop planting, the use of water saving technologies and other such factors.

Therefore, exploring the factors that influence the irrigation water demand, and quantifying their contribution to that demand could provide insights on controlling the scale of agriculture.

抛开词汇表达不说，这两个句子中都出现了逗号的不恰当用法。在这些细节处给审稿人留下「不严谨」、「不规范」的不良印象，岂不是辜负了自己苦心费力写出的Essay？

Essay写作中“逗号”你用对了吗？

Essay写作逗号使用一

句子中包含数量≥3的单词，词组或者分句时，用逗号将其分隔开来。特别是在连接最后一个要素的并列词之前也加上逗号。

例如刚才提到的Essay原稿中的句子：

Demand for irrigation water is mainly influenced by climate change, the scale and patterns of crop planting, the use of water saving technologies and other such factors.

标点符号应改为：

Demand for irrigation water is mainly influenced by climate change, the scale and patterns of crop planting, the use of water saving technologies, and other such factors.

推荐表达为：

Demand of irrigation water is mainly influenced by climate change, the scale and patterns of crop planting, the use of water saving technologies, and other factors(and so on).

Essay写作逗号使用二

句子中连续的词组或者分句最后是以表继续或者省略的词组结束时，例如「and so forth」「and so on」「and the like」这样的词组，需在其前面加上逗号。若这类词组后面还接有其它句子成分，则可酌情添加逗号来避免歧义。

例如：

Using such techniques, management can improve not only productivity but also hours, working conditions, training, benefits, and so on, without reducing wages.

Essay写作逗号使用三

非限制定语短语出现在句子中需用逗号分隔。

例如：

The professor, wearing a blue hat, attended the conference.此处「wearing a blue hat」为非限制定语短语，用逗号分隔；

The lady wearing a blue hat is the professor.此处「wearing a blue hat」为限制性修饰，勿使用逗号。

Essay写作逗号使用四

介绍性的词组，例如「for instance, for example, in other words，that is」出现在句首时，后面需加逗号；若出现在句中，则前后都使用逗号来进行分隔。

例如：

That is, researchers still have hunches and use exploratory methods.

Some methods ,however, are particularly well suited to applying all three, for example, grounded theory as explained by……

Essay写作逗号使用五

句子中出现的连接副词，或者副词词组，都需要用逗号分隔。

例如：

Nevertheless, it is a matter of great significance.

Recently a significant effort to model these systems has also examined in particular, the role of this element in determining the behavior of……

Essay写作逗号使用六

复合句中的并列词，类似「and, but, or, so, yet」等，连接两个独立句子并且这两个句子在含义上需要一个停顿的话，我们在这些并列词前面需加上逗号。但是如果并列词连接的是并列主语或者谓语则不用加逗号。

例如文章开头提到的Essay原稿中的句子：

Therefore, exploring the factors that influence the irrigation water demand, and quantifying their contribution to that demand could provide insights on controlling the scale of agriculture.

应修改为：

Therefore, exploring the factors that influence the irrigation water demand and quantifying their contribution to that demand could provide insights on controlling the scale of agriculture.

此处「exploring the factors that influence the irrigation water demand」和「quantifying their contribution to that demand」为该句的并列主语，用and连接但是不加逗号。

以上就是关于Essay写作中逗号的使用讲解，希望大家看完之后，都知道怎么正确使用逗号了。
