Should 应该；将要；可能；就短句：i should rather say no to the school bullying You should speak english in english class Maybe I should say sorry to her. Must 必须，一定；很可能；可以，应当短句: You must start the project from main idea. I must go to the office And now we must go, to the library.如果你说的是应该的话，我更建议你用第一个should，第二个must无论在语气上或用途上更显的肯定一点，一定要怎样怎样。
