词根mot表示“运动”，今天小编就带来几个由它构成的动词。
- promote=pro+mot+e
含义：推动；推广；晋升。比如：
promote economic growth
推动经济增长
She was promoted to senior manager.
她被提升为高级经理。
解释：前缀pro-表示“向前”，词根-mot表示“运动”，让事物向前运动也就是“推动；推广”的意思。如果在职场上让某人前进，那就意味着“提升某人”。
- demote=de+mot+e
含义：降级；降职。 比如：
He was demoted because he had lost an important client.
他因为丢掉一位重要的客户而被降职。
解释：前缀de-表示“向下”，词根-mot表示“运动”，因此合起来的本意是向下运动。如果让某人往低处走，那不就是“降级，降职”的意思吗？
- motivate=mot+形容词词尾iv(e)+动词词尾ate
含义：激励，激发。比如：
She's very good at motivating her students.
她非常擅长激励她的学生。
How do you motivate people to work hard and efficiently?

- motion=mot+词尾ion
