不用加空格的。 一些和括号有关的标点用法: 1 一般有括号的句子时候逗号和end punctuation放在括号外面: Three of my four uncles served with honor in the war (the other was too young to enlist) 2 如果括号内的东西自己就是完整的句子,则括号内可以有自己的end punctuation: Three of my four uncles served with (The other was too young to ) 3 如果括号内有属于自己内部的问号和叹号,则在最后括号外任然需要一个标点: Miranda's frequent exclamations express pity ("O, woe the day!" "O the heavens!" "Alack, for mercy!") and wonder ("O, wonder!" "O brave new world!") 如果是标出出版物或者人的生死年份一类的看下面的例句: They are used following quotations to cite page references (see QL: Quoting Literature in Part Five) Waslaw Nijinsky (1890-1950) 最后,尽量不要用括号。。真的 我在美国读书的,曾经在刚来的时候上comp2的时候一个paper用了好几个括号,老师直接给D的。。
