托福写作,你的关注点都在词句运用、句子语法、文章逻辑上,标点符号被遗忘在了角落,但是你可知道,标点用错了很可能导致扣分,标点符号运用得当却能给文章添色加彩提分数。今天聚培训小编就给大家介绍下托福写作的逗号和撇号怎么用才对。
,逗点
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。
The principal reason for this is that noneof them possesses chlorophyll, and since they cannot synthesize their owncarbohydrates, they obtain their supplies either from the breakdown of deadorganic matter or from other living organisms.
2.用逗号来分隔一系列单词、词组和从句。
Furthermore the walls of fungal cells arenot made of cellulose, as those of plants are, but of another complex sugarlike polymer called chitin, the material from which the hard outer skeletons ofshrimps, spiders, and insects are made.
They are a major cause of structural damageto building timbers, a cause of disease in animals and humans, and one of thegreatest 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。)
Chemical fertilization, for example, helpsto 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。
For men, heroism was usually described asbravery and the active, successful over coming 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。
(1) 同位语。
The canopy, the upper level of the trees inthe rain forest, holds a plethora of climbing mammals of moderately large size,which may include monkeys, cats, civets, and porcupines.
(2) 从句。
The canopy, the upper level of the trees inthe rain forest, holds a plethora of climbing mammals of moderately large size,which may include monkeys, cats, civets, and porcupines.
6.逗点用于直接引用的句子之前,如Mary said, "Let's go fishing."(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。)在反问句之前要使用逗点:He worked very hard, didn't he?
’撇号
1. 用来表示省略,比如:I’m I’ve I’d
需要注意的是,will not缩写成won’t,属于一个特殊的形式。另一点,更为重要,就是在书面语种,尽量不要使用缩写形式。
2. 表示所有关系
表示诸如:belongs to, possessed by, owned by, and of
用撇号表示所属关系是最为简便快捷的(quickest and easiest),这对英语,尤其是美式英语来说非常重要。
3. 如果是单数以-s结尾的词,所属形式是-‘s,比如:Doris’s。但是如果是以-s结尾的复数,则直接加-‘,例如:parents’。
