15．A few changes about how a teacher runs a classroom can make a huge effect on how concentrated students will be in that classroom．It's an issue every teacher has to face．（36）C Here are just a few of my strategies．
•Rearrange （重新安排） Seats．
I did the seat rearrangement because class conversation had become dull，and students just seemed to be there but not actually there．（37）E I had all of my students pick new seats at the tables．The rules were simple．They could not sit with more than one other person they'd already sat with，and it had to be at a different table．
•Take over A Lesson．
Once in a while，it can be fun to let the students take over a lesson in a unit．Let them become the teachers，and the teacher becomes the student You can provide the topic they need to cover．（38）D
•Have Open Projects．
Open projects have been very successful in my class．（39）G I used to dictate every part of my project assignments．Students would ask to do things a little differently．And I'd give in，surprised that their ideas were better than mine．
•（40）A

B．Listen carefully．
C．But it can be solved in some very simple ways．
D．Let the students choose the topic and teach whatever they want．
E．It's one of the simplest ways to rearrange a class and get things going again．
