英文中有小括号。一、小括号表示附加或补充。如：The day before one of my midterm history exams, I still hadn’t found time to read the first book on the reading list. (That, of course, is a very common disease at Harvard.) 在期中历史考试的前一天，我还未曾找出时间阅读书单上的第一本书哩。(这当然是哈佛的一种通病。)二、小括号表示数码。I prefer the gray suit because (1) it is made of material that will not wrinkle easily and (2) it is conservative in color and pattern. 我选择灰色服装，因为(1)其料不易有皱褶，(2)其颜色和式样也朴素。三、小括号表示非限制性定语从句，当然这里也可以用逗号来代表非限制性定语从句。The President (who is arriving today) has been ill. 总统(今天到达)刚生过病。四、小括号表示列举事物，也可以用冒号表示列举事物。Don’t eat too many dairy foods (milk，butter，and cheese). 不要吃太多的奶制品(牛奶、牛油和奶酪)。五、在数学算式中，小括号表示要先算括号内的算式。如：(3+1)÷2=4÷2=2.希望我能帮助你解疑释惑。
