Question

15．我可以把这件事告诉你，但是你必须保密．
I can tell you about it，but you mustkeep it to yourself．

Answer 1

分析 keep it to yourself

解答 答案：keep it to yourself．表示保守秘密用keep sth to oneself，主语you，故yourself，故答案是keep it to yourself．

点评 keep sth to oneself 一般是表示保守秘密，比如：would keep this to yourself 你能保守这个秘密吗？keep sth for oneself表示为某人保留某样东西，如：I will keep this bag for yourself．我会为你保留这个包．
