Time expressions: At this moment, every day, never, usually, sometimes, now...

[Estela]

the time expressions like: At this moment, every day,never, usually, sometimes, now, always need I to put at the end of a sentence?

[Jamie (K)]

No, they can go in various parts of the sentence, but some of them have some special restrictions. In fact, "never" can't go at the end of a sentence at all.
