"Please check one more time."

Translation: 请再检查一次。

[oLs_st]

请再一次检查.. why is this not correct?

[KX3.]

The sentence is hanging, it needs something at the end to complete it. It'd be correct if, for example, a noun were to follow, e.g. 请再一次检查行李/考卷, but is still less commonly used.

[RobinThor]

What do you mean? The sentence is hanging?

[KX3.]

The sentence needs a noun to complete it, in this case. However, colloquially, in the right context, it may be used.

[CinnamonTe1]

I know you said it sounds better with a noun, but what about 请一次再检查 ? Does 一次 have to come at the end or just after 再？ Is 一次 treated like a duration where it's supposed to come after the verb?

[1b4q4]

Why do we need 再 here?

[KX3.]

Without it, 请检查一次 = Please check once.

[rianwardana]

Thank you

[phanter]

Can we say 请检查再一次？

[KX3.]

You can say 请检查（再）多一次, the 再 in the bracket is mainly for colloquial usage only.

[kuyaC]

Why isn't 请在检查 enough?

[maximilien369]

(Considering you wanted to write: 请再检查 and not 请在检查)

一次 means one more time. Without it: 请再检查 becomes a hanging sentence and only means: Please check again.

This the third time in this lesson that the correct answer has been marked wrong. It mystifies me how this can be such a constant problem.
