This worksheet is assigned to intermediate students of English. It is based on the way we usually form questions in English. Some students get confused with the fact that sometimes we don't form questions using auxialiries or inversions. It all depends on the WH-word as subject or as object. When the WH-word is the subject of the sentence, the question is not formed with auxiliaries or inversions. On the other hand, when the WH-word is the object, an auxiliary or inversion is needed.
