修改原因
修改前When I lost my job, my friends stood for me and helped me find a new one.
修改后When I lost my job, my friends stood by me and helped me find a new one.
Stand for 看起来也像支持，但它可以表示代表某种含义，如 What does UN stand for?，或支持某种理念、原则。困难中陪伴和支持一个人，则用 stand by：stood by me。
不带小品词的 stand 可以表示忍受，常见于否定句：I can't stand loud music。Stand up for someone 强调别人被批评时出面维护：She stood up for me at the meeting。Stand by 则强调始终站在对方一边，不离弃。
动手练习

查看答案
stand by — 你承诺他遇到困难时会支持他，所以用 stand by him。Stand 单独表示忍受时，常见于 I can't stand him 这样的否定表达，不能表达这里的支持承诺。
想一个在困难时支持过你的人。使用 stand by，说明当时的情境，以及对方具体怎样帮了你。
When I moved to a new city and felt lonely, my old school friend stood by me and called me every evening.
