When I began teaching in a university, I was invited to a workshop for new professors. I had ____ a long time learning what to teach, but not learning how to ____ it. Somehow, my university seemed to hope a weekend spent with experienced professors would ____ for that. My colleagues presented well­crafted lectures about the tools they used. I enjoyed their ___， but do not remember a thing they said. At a coffee break during the lectures, finding myself ____， I turned to a mathematics professor standing nearby. I asked him what his favorite teaching ____ was. “A cup of coffee，” he said, “I talk too much and too fast in the classroom. Students sometimes have trouble ____ me. So when I've said____ that I want my students to think about, I would____ and take a sip of coffee. It lets what I've just said sink in.” When we were called to the next talk, he put down his cup and I ____ there was not a trace of coffee in it. “My doctor ____ me to stop drinking coffee，” he explained. “So I have always used a(n)____ cup.” I decided to try his ____ in my class. I took a cup of coffee with me to my next class. It helped. My pauses, as I ____ the coffee, not only gave my students ____ to think about what I had said, but gave me time to think about what I was going to say next. I began to use my ____ to look around the room to see how my students were reacting to what I had just said. When I saw their ____ wander, I tried to bring them back.

My ____ became less organized and less brilliant, but my students seemed to ____ me better. 小题1: A．wasted B．cost C．killed D．spent 小题2: A．manage B．copy C．teach D．consider 小题3: A．put up B．build up C．take up D．make up 小题4: A．experiences B．plans C．presentations D．designs 小题5: A．alone B．absent C．lonely D．awkward 小题6: A．method B．material C．tool D．skill 小题7: A．following B．grasping C．seizing D．imitating 小题8: A．everything B．something C．nothing D．anything 小题9: A．pretend B．stop C．prevent D．delay 小题10: A．observed B．noticed C．glared D．proved 小题11: A．suggested B．protected C．allowed D．advised 小题12: A．empty B．clear C．large D．false 小题13: A．discovery B．invention C．magic D．idea 小题14: A．dropped B．made C．drank D．changed 小题15: A．space B．time C．room D．schedule 小题16: A．chances B．pauses C．situations D．conditions 小题17: A．attention B．focus C．energy D．devotion 小题18: A．translated B．expected C．explained D．solved 小题19: A．speeches B．memories C．documents D．lectures 小题20: A．realize B．understand C．admit D．admire
