1,短句应该一气呵成,但为了强调某个部分可以重读并稍微停顿一下.下面用连字符间隔的部分就是可停顿部分.This major-- can bring me- a lot of fun and happiness.2,如果句子较长,可以按照意群停顿.千万不可中断意群.下面用同样方法表示,供你参考：And after graduation - I want to be a teacher of this major-- in my hometown-- to make contribution to my contry.It's a big public university-- with excellent resources and diversfied student groups .It's full of great opportunities-- for students to learn and to grow.I can keep a stable and honorable occupation-- with high earning and excellent welfare- in China.
