FeiFei-120 的严肃讨论

120. In Europe, schoolchildren devote time during each school day to calisthenics. North American schools rarely offer a daily calisthenics program. Tests prove that North America children are weaker, slower, and shorter-winded than European children. We must conclude that North American children can be made physically fit only if they participate in school calisthenics on a daily basis.

Which one of the following is assumed in the passage?

A.       All children can be made physically fit by daily calisthenics.

B.        All children can be made equally physically fit by daily calisthenics.

C.        Superior physical fitness produces superior health.

D.       School calisthenics are an in indispensable factor in European children’s

E.        North American children can learn to eat a more nutritious diet as well as to exercise daily.

參考答案：D 不過D選項好像沒有講完???

思路：calisthenics=健美體操

 North American schools rarely offer a daily calisthenics program. Tests prove that North America children are weaker, slower, and shorter-winded than European children.無法推得

calisthenics program是唯一使NA physically fit的原因

除非那是European非有不可的因素

A.        不需要ALL都是

B.         無關選項,和equally無關

C.         無關選項

D.        正確答案,補洞

E.         無關選項（無關對比）
            而且as well as強調前者

---------------------------------------------------------------------------------------------------------------------

以上是原注解，我认为选D是不对的。A应该是正确选项。A项里的"all"实际上是指代“north america children”and “Europe children”.

D 项里的意思是偏离了conclusion 里的重心（结论里的重心是"north america children" 可不可以变得强壮）。

从其选项的设置来看A，B比较像，这是另外一个暗示，正确选项是A，B 里的一项。

请指正！

我也认为是A，D感觉跟题目没有直接性关系，至少D答案中根本没有提到跟NORTH AMERICAN学生的联系：（为什么是D呢
