I was about to leave while a shout came from behind?while错,应是when。 when表示一个时间点,while表示一个时间段,此处came是点动词,故用when。I went to work by taxi in order to not be late again 介词短语in order to not 错，应为in order not to。不定式的否定形式是not to 而非 to not。What do you think shall we do next?语序错误，正确语序为：What do you think we shall do next?what we shall do 作think 的宾语，是一个宾语从句，在从句中，主语和谓语的位置不能颠倒。We can work out the math puzzle by several different ways。将介词by换为 in。。
