Directions: Renumber the sentences given below to arrange them in what you think is the best order. 1. When the instructor sees that you are not involved in the class, he or she may pop a quick question, probably hoping to embarrass you. 2. If the instructor then asks you why you don’t know the answer, say, “I thought the assignment was boring, so I didn’t do it.” 3. First of all, show up late so that you can interrupt the beginning of the instructor’s presentation. 4. After the instructor calls on someone else, get up loudly from your seat, walk to the front of the classroom, and demand to be excused for an emergency visit to the washroom. 5. There are several steps you can take to harass an instructor during a class. 6. If the instructor asks you where you’ve been when you reenter the room, simply ignore the question and go to your seat. 7. Then just sit and do anything but pay attention. 8. Ten minutes before dismissal time, start noisily packing up your books and papers. 9. You should then say, in a loud voice, “I DON’T KNOW.” 10. The instructor will look at you and wonder whether it wouldn’t have been better to go into business instead of education. 11. Stay there at least fifteen minutes and take your time coming back. 12. Then get up and begin walking to the door a couple of minutes before the class is supposed to end. 请把你的排序方式写在空格处！数字之间用一个空格分开。
