1)Because she needed some money to buy a book, she cashed a check. 2)Needing some money to buy a book she cashed a check. Are these two sentences different?? No they're not. often an "ing" phrase at the beginning of a sentence, give the meaning of "because". In second sentence "because" is a omitted. but the meaning of two sentences are the same. you can omit "because" and start a sentence with "ing" which means because. Now it is your turn can you give me some examples??
