第二套14
The average hourly wage of television assemblers in Vernland has long been significantly lower than that in neighboring Borodia.  Since Borodia dropped all tariffs on Vernlandian televisions three years ago, the number of televisions sold annually in Borodia has not changed.  However, recent statistics show a droip in the number of television assemblers in Borodia.  Therefore, updated trade statistics will probably indicate that the number of televisions Borodia imports annually from Vernland has increased.




第三套25题
Q25:
Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because aging by itself brings about a loss of creative capacity.  However, a study has found that almost all scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs.  Since creative breakthroughs by scientists under forty also generally occur within a dozen years of the scientist’s entry into the field, the study’s finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.

第一题有挺多废话 总的说来就是 B地电视机年销售量不变 意思就是需求不变 可是B地造电视机的人少了 因此得出结论 要从别地进口多些电视机
C的意思就是造电视机的人的效率没有上升 取非的话 就是效率变高了 人手即使少了 但是还是可以造出和以往同等多的电视机 那么在需求刚才说过不变的情况下 就不需要从别地进口电视机了 关税还有工资什么的都别管
