write down的用法：write sth down与write down sth都正确。例如，write your ideas down，write down your ideas。
write your ideas down和write down your ideas两个都对。
down是一个副词，这是一个由“动词+副词”构成的短语动词，名词作宾语时既可放在后面，也可放在中间；如果是代词作宾语，只能够放在动词和副词之间，不能放在副词后面。再如pick it up;pick the book up,pick up the book都可以。
如果是“动词+介词”构成的短语，无论名词还是代词作宾语，都应放在介词的后面，如look after your brother，look after him，而不能放在介词的前面。
