Choose the correct preposition. 1) I'm tired (of) waiting for you. 2) He hasn't smoked (since) ages. 3) Nina is good (at) running. 4) I'm looking (for) my keys. Has anyone found them? 5) They dream (of) moving to South Africa. Hi there!! It's question about preposition again. By the way, I don't understand question number2. Isn't there anything missing word?

Hello there! Thank you for doing your homework..It\'s good to practice using prepositions because they are always confusing..In question number 2, the answer is \"for\" because the word\" ages\" is a duration that means \"for a very long time\". I\'ll explain further in class.. See you! T.
