1) Neither of my friends visit some very often. (dlaczego nie mogę 'either')
2) On no condition will they be to open fire without warning. (co to za konstrukcja?)
3) No sooner had I arrived home than the phone rang. (than? jak?)
4) My car breaks down a lot. I always have it repaired by the mechanics at the local garage. (nie powinno być tam "repairs it", jest tam "always")
5) Not until I got home did I realise my mistake. (znowu dziwna konstrukcja)
6) Here comes John (a nie 'is coming'? przecież to ma wiecej sensu).
