He usednt to come here.他过去不常来。Exercise单项选择。1.She helps_the house.A.clean up B.cleans upC.cleaning up D.cleaned up2.I took my sister to the concert to _.A.cheer up her B.cheer her upC.cheer she up D.cheer up she3.Were thirsty.We hope _ some water.A.drink B.drinkingC.to drink D.drinks4.Did John_ the books to the students this morning?A.gave out B.give upC.give out D.give over5.Playing on the road is very dangerous,so my mother always asks me _on it.A.dont play B.not playC.not to play D.to play6.Did you _ in the morning?
