Question

"of the top of one's head"
这句如何翻译

谢谢

Answer 1

不是of the top of one's head
而应该是：

off the top of one's head

means:
Without much thought or calculation

From Ansears.com:
http://www.answers.com/topic/off-the-top-of-one-s-head

In an impromptu way, without much thought, as in Off the top of my head I'd say we'll double our profits in a year. This idiom suggests one has not used the inside of one's head before making some statement. [Mid-1900s]

意思是，（表示说话）没有经过更多的思考和考虑（武断；或脱口而出；或即兴）

Answer 2

举例说明：I can't think of any good example off the top of my head.
就是说：我不能想到任何好的例子。

Off the top of one's head 只是单纯的熟语式的用法，不是说什么“头等要事”。要翻译，也只能是：“我脑海里”、“我的记忆里”等等。本回答被提问者采纳
