修改原因
修改前My manager always runs down me in front of the whole team.
修改后My manager always runs me down in front of the whole team.
容易把宾语放在整个短语后面，写成 runs down me。但宾语是 me、him、it、yourself 等代词时，要放在 run 和 down 之间：runs me down、stop running yourself down。名词则也可以放在 down 后面：runs down my ideas。
Put down 表示用刻薄的话伤害某人，通常是当面对方说：He put me down in front of my friends。Run down 的范围更广，可以当面或背后贬低一个人，也可以批评其工作、某家公司或一座城市：She's always running down her home town。
