雅思写作标点符号如何正确使用?

雅思写作中标点符号也是影响分数的原因之一，考官们主要从句子结构的多样性和准确性外，标点符号也是一个很重要的评价标准，可是同学们往往因为这个点太小而将其忽视了。小编给大家整理了雅思写作中标点符号如何正确使用?的相关内容，我们一起来看下吧~

1.流水句

问题句：It is universally acknowledged that young people tend to be impulsive, most of them are always judged as troublemakers.

修改后：It is universally acknowledged that young people tend to be impulsive. Most of them are always judged as troublemakers.

上述句子中，分别有两个独立句子。第 一个是it is universally acknowledged that young people tend to be impulsive。第二个是most of them are always judged as troublemakers。与中文不同，英文中两个独立的句子需要用句号分隔开，或是用上连词(and,but,however, as, because，while, although等)。因此，这两个句子中间应该打句号。修改后，需注意第二句开头单词首字母需要大写。如果希望维持句意且依然想要用逗号，那么使用从句也是可以的，如：It is universally acknowledged that young people tend to be impulsive, most of whom are always judged as troublemakers.

2.并列句中的逗号误用

问题句：Children usually have little respect for their teachers, refuse to obey school rules.

修正后：Children usually have little respect for their teachers and refuse to obey school rules.

上述句子中，主语后面有两个并列成分，一个是have little respect for their teachers。另一个是refuse to obey school rules。与中文不同，当两个成分并列时，这两个成分之间用并列连词，如and, or, as well as, but 等，而不用逗号。因此，根据句意，此句中的逗号应改为and。当然，这并不意味着所有的英语并列成分都得用并列连词。例子如下：

问题句：Advertisements are hardly so powerful as to persuade all people into buying the same clothes and electronic gadgets and furniture.

修改后：Advertisements are hardly so powerful as to persuade all people into buying the same clothes， electronic gadgets and furniture.

显然，这个句子中有三个并列成分，分别是the same clothes, electronic gadgets和furniture。在英语中，当三个或三个以上的成分并列时，其中第 一个成分后用逗号，而后面两个成分之间用并列连词。因此，此句中的第 一个and应改为逗号。

3. 限定性从句和非限定性从句的逗号使用

问题句：Some young people cannot break their bad habits which will harm their health.

修改后：Some young people cannot break their bad habits, which will harm their health.

在上述句子中，which will harm their health 指的是some young people cannot break their bad habits (一些年轻人不能改掉坏习惯)的不良后果，起补充说明作用，而不是特指、限定坏习惯是哪些坏习惯，所以应该在which使用逗号，构成非限制性定语从句。

大家可以对比一下下面两句话。

A.The region which generated the largest amount of waste was criticized by the government. (限定性定语从句)

B.B. Machula, which generated the largest amount of waste was criticized by the government. (非限定性定语从句)

第二句中，定语从句部分只是对Machula这个地点进行补充说明，没有起到限定作用，因此需要打逗号。

4.状语从句放句首时，漏写逗号

问题句：As for the bar chart shows the changes in average house prices in different cities.

修改后：As for the bar chart，it shows the changes in average house prices in different cities.

在问题句中，考生可能由于语法知识不够扎实，会错误的把as for the bar chart当作句子的主语，导致语法错误。但实际上，as for the bar chart只是个介词短语，只能充当句子的状语，不能充当主语，所以，应该在as for the bar chart后面打上逗号，然后用代词it充当句子的主语。

总结：

写作语法评分标准GRA中，有明确对于标点符号使用准确性的评价，而同学们最容易忽视的标点符号使用规范即：

1. 句子与句子之间没有连词的情况下，用句号。

2.当两个成分并列时，这两个成分之间用并列连词，如and, or, as well as, but 等，而不用逗号。当三个或三个以上的成分并列时，其中第 一个成分后用逗号，而后面两个成分之间用并列连词。

3. 非限定性定语从句前应该使用逗号，从而避免造成语义上的偏差。

4. 当状语放句首时，这个状语后面一定要写逗号，然后再写主句。
