你几时走？

What time are you leaving?

wǒ bù zhī dào tiān xiàn shì jǐ shí gěi chuī dǎo de

我不知道天线是几时给吹倒的。

I don't know when the aerial blew down.

shuí yě méi zhù yì nà xìn tiān wēng jǐ shí bù jiàn de

谁也没注意那信天翁几时不见的。

Nobody noticed when the albatross had disappeared.

nǐ men jǐ shí yǒu kòng jǐ shí lái

你们几时有空几时来。

Come when you are free.

nǐ men yuàn jǐ shí qù jiù jǐ shí qù

你们愿几时去就几时去。

Go whenever you want to.
