6. At the end of the Second World War the number of women in their childbearing years was at a record low. Yet for almost twenty years they produced a record high number of children. In 1957 there was an average of 3.72 children per family. Now the postwar babies are producing a record low number of babies. In 1983 the average number of children per family was about 1.79-two children fewer than the 1957 rate and lower even than the 2.11 rate that a population needs to replace itself.

(A) for the birth rate to be high, there must be a relatively large number of women in their childbearing years
(B) the most significant factor influencing the birth rate is whether the country is engaged in a war
(C) unless there are extraordinary circumstances, the birth rate will not dip below the level at which a population replaces itself
(D) for the birth rate to be low, there must be a relatively small number of women in their childbearing years
(E).the birth rate is not directly proportional to the number of women in their childbearing years

8. The best argument for the tenure system that protects professional employment in universities is that it allows veteran faculty to hire people smarter than they are and yet remain secure in the knowledge that unless they themselves are caught in an act of moral turpitude-a concept that in the present climate almost defies defini- tion-the younger faculty cannot turn around and fire them. This is not true in industry.
Which of the following assumptions is most likely to have been made by the author of the argument above?
(A) Industry should follow the example of universities and protect the jobs of managers by instituting a tenure system.
(B) If no tenure system existed, veteran faculty would be reluctant to hire new faculty who might threaten the veteran faculty's own jobs.
(C) The traditional argument that the tenure system protects scholars in universities from being dismissed for holding unconventional or unpopular beliefs is no longer persuasive.
(D) If a stronger consensus concerning what constitutes moral turpitude existed, the tenure system in universities would be expendable.
(E) Veteran faculty will usually hire and promote new faculty whose scholarship is more up-to- date than their own.英语作文
