It wasnt for you!你本不该拆开这封信，它不是写给你的 (3)ought to的否认形式为ought not to或oughtnt to，其一般疑问句形式是将ought置于主语前 You oughtntought not to blame him 你不应当责怪他。 一Ought I

30、没必要做某事You neednt have told me the news. 你本没有必要告知我这个消息【提示】(1)由于用作情态动词的need通常不用于确定句，所以对于以need开头的疑问句的否认答复可用neednt，但是确定答复却不能用Yes，I need之类的，而常用Yes，I must来回答例如：一Need you go now?你须要如今走吗?一Yes，I must是的，我必需如今就走。一No，I neednt不，不必(2)由must引出的一般疑问句，确定答复用must，否认答复用neednt或dont have to。一Must I do the work now?我必需如今干这
