Why is the ground all wet? (flood) The ground was all wet because of the flood.2. Why is he so happy? (got an A for English)3. Why is she so sad? (lost her pen) 4. Why is the baby crying? (hunger) 5. Why didnt you go to the show? (the maths exam)Work out the rules:We can use “because” and “because of” to give the reason(s) for something.The word “because” introduces the clause of reason and we usually put it in the middle of a sentence. We use a noun, a noun phrase or a pronoun after “because of”.
