delay 的用法

delay
vt.
延期, 延缓; 推迟
We decided to delay our holiday until next month.
我们决定将休假延至下个月。

所以应该是delay doing

delay doing sth.=you do not do it immediately or at the planned or expected time, but you leave it until later.
EG: For some reasons I wanted to dlay me dparture until June.

delay doing
delay (for) ### hours .....
be delayed by....

delay作动词时，后面可直接加名词，例如：The chairman will delay the meeting. 如果后跟动词，则要用-ing形式，即：delay doing sth. 例如：He delayed telling her the news.
