I need to give you a really difficult one. I'll go to the back of the book. Prepositions are the thing that learners have the most difficulty with. You've got to put the preposition in the right place in the gap. Why are you always so rude? Your parents. Can't you be nice? They're little words like of to at in. Come on. So this is the next one. It was very nice. To do my shopping for me. But I don't know why. The present you gave me. With yes. Well done.
