1.Why don't you go to school now? I want to go to school by taxi.The taxi will come in twenty minutes. Couldn't you walk to your school,it is not far away，just 2 kilometers. No. Shouldn't you save your money,you always say that you have no money and life is too bad. I am too tired，I just want to take a taxi. 2. Wouldn't you rather take the plane,I want to see you in five hours. I would rather take the train，I like the beautiful scenery outside the window. 3.Don't you look beautiful now,your dress is too beautiful. 4.Aren't you smart,you have solved the problem in 2 hours.
