About "ne" and "he":

You can use "NE" instead of "HE" (MEANING: they) in spoken Finnish, but when you write you should use "he", it's the correct form.

And yes, as someone else said there's a little mistake in this sentence:

They move to Espoo. = He muuttAvat Espooseen.

Well done!! // Hyvin tehty! :))

My namesake missed one mistake:

6. They move to Espoo. = He muuttavat Espooseen.

Käännä suomeksi

1. I live in Oulu = Asun Oulussa.
2. Are they in school? = Ovatko he koulussa?
3 Where do they live? = Missä he asuvat?
4. He is in the shower = Hän on suihkussa.
5. Go to your room! = Mene huoneeseesi!
6. They move to Espoo. = He muuttuvat Espooseen.
7 We are at home. = Olemme kotona.
8. They are in Moscow = He ovat Moskovassa.

Kun puhutaan elävistä olennoista sanotaan "he".

Muuten lauseesi ovat virheettömiä! Onneksi olkoon!
