[不定项选择题]共用题干 My Life at Renda
I learned very quickly that being a teaching assistant(T A)at the University of Iowa would be different from a teacher at Renmin University.______(46)Eyes staring,mouths open, students examining my big nose,hands nervous,people whispering while I wrote my name on the blackboard.
At Iowa,when my first classes began,half my students still hadn't arrived.When everyone finally found a seat,ringing cellphones and loud yawns（哈欠）interrupted my opening remarks.
It is not that American students were disrespectful.______(47)They were,however,far more skeptical than the students I had at Renda. The truth is I couldn't fault them for their skepti- cism.Undergraduates at large US universities-especially freshmen and sophomores-often have several classes a semester handled by TAs.In some.cases,the TA sets the course content. ______(48)Most have good intentions,but only a few are as effective as flesh-and-blood pro-fessors.
Every teacher has to confront obstacles to learning-no matter what the culture.Students who talk during lectures,students who cheat,students who question the grade they get for a paper or project-dealing with these is all part of the job.______(49)
The difference,I think,is that in the US I had to swallow more of my pride.______(50) I had a responsibility to teach them,of course,but I had to do so indirectly-as a guide who himself had a few things to learn from the students. ______(48)
A.Back at Renda,I had walked into my first classes feeling like a celebrity.
B.In my students' minds,I had little to offer them,except perhaps some sample questions for the mid-term exam.
C.In others,the TA works as a grader and discussion leader.
D.I encountered these in China,and I faced them in the US.
E.On the other hand,being taught by a graduate student is not necessarily bad.
F.Most were polite,or at least,indifferent.
