My Life at Renda

I learned very quickly that being a teaching assistant (TA) at the University of Iowawould be different from being a teacher at RenminUniversity.

(46) Eyes staring, mouths open, students examined my big nose, while Iwaswriting my name on the blackboard.

At Iowa, when my first classes began, half of my students still hadn't arrived. Wheneveryone finally found a seat, ringing cell-phones and loud yawns (哈欠) interrupted myopening remarks.

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 gradethey 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 aguide who himself had a few things to learn from the students.

DOn the other hand, being taught by a graduate student is not necessarily bad. EMost were polite, or at least, indifferent

FBack at Renda, I had walked into my first classes feeling like a celebrity

Middle Age: A Low Point for Most

People around the globe hit the height of their misery and depression in middle(51), a new international study suggests.The finding by British and American researchers was based on an analysis ofwell-being among approximately 2 million people in 80 nations. With few exceptions, theobservation appears to apply acrossthe board, regardless (52) gender (性别), culture, geography, wealth, jobhistory, education, and marriage or parental status.

In the United States, however, some as-yet unexplained(60)differenceswere observed, with happiness among men dipping the most in their early 50s, whereaswomen hit their nadir (最低点) around the age of 40. The researchers cautioned that cheerful people tend to live longer than unhappy
