在托福写作中标点符号的使用也会对文章的整体起着重大的作用哦!中文和英文在逗号的使用上有着很大的不同,你会正确的使用它们嘛?在托福写作中合理正确地使用逗号往往会让文章更加出色!o(≧v≦)o~~
在逗号的使用上有以下几种技巧:
1、在并列连词(and,but,for,nor,or,yet )前使用,用来连接句中的各分句。
例句:The principal reason for this is that none of them possesses chlorophyll,and since they cannot synthesize their own carbohydrates,they obtain their supplies either from the breakdown of dead organic matter or from other living organisms.
2、用逗号来分隔一系列单词、词组和从句。
例句:Furthermore the walls of fungal cells are not made of cellulose,as those of plants are,but of another complex sugarlike polymer called chitin,the material from which the hard outer skeletons of shrimps,spiders,and insects are made.
They are a major cause of structural damage to building timbers,a cause of disease in animals and humans,and one of the greatest causes of agricultural losses.
3、逗号用来分隔与句子其他部分密切相连的简短插入语或旁白。(较长的,更为突兀的或复杂的插入成分的则用破折号或圆括号。)
例句:Chemical fertilization,for example,helps to produce better crops,but is harmful to the environment.
4、在并列形容词,即分别修饰同一个名词的形容词之间使用逗号,但也有的形容词之间不加逗号的。
例句:For men,heroism was usually described as bravery and the active, successful overcoming of adversity.
5、 用逗号来分隔非限定性修饰语,即该修饰语对于句子的意义并非必不可少。非限定性修饰语与限定性修饰语的区别在于,它即使被省略,也不会改变句子的主要意思。
例句:The canopy,the upper level of the trees in the rain forest,holds a plethora of climbing mammals of moderately large size,which may include monkeys,cats,civets,and porcupines.
