GWD26-Q29 还没讨论过的,大家看看啊!


    

GWD26-Q29


    

Educational Theorist:


    

Recent editorials have
called for limits on the amount

        
of homework
assigned to children. They point out that free-time activities

        
play an important role in childhood development and
that large amounts of

        
homework reduce
children’s free time, hindering their development. But the

        
average homework time for a ten year old, for
example, is little more than

        
30 minutes
per night. Clearly, therefore, there is no need to impose the

        
limits these editorials are calling for.


    

Which of the following is
an assumption on which the educational theorist’s

        
argument relies?


    

A.     
The free-time activities that ten year olds engage in most
are all

        
approximately equally
effective at fostering development


    

B.      
Regularly doing homework assignments improves children’s
academic

        
performance.


    

C.     
Individual teachers are not the best judges of how much
homework to

        
assign the children they
teach


    

D.     
In most schools, if not all, the homework assignments given
are of a length that does not diverge widely from the average.


    

E.      
Free-time activities rarely teach children skills or
information that they

        
can use in their academic
work.



我觉得C好些,答案是D。大家觉得呢?

用平均数得出的结论应该还要同时考虑样本的偏差

对D取非:

In most schools, if not all, the homework assignments given are of a length that does diverge widely from the average.

布置的家庭作业时间偏差很大,就是说某些学校布置家庭作业做的时间可能会很长. -> 实施limits将会有效果.
