提问:

( Even though its per capita food supply hardly increased during ) two decades, stringent rationing and planned distribution have allowed the People’s Republic of China to ensure nutritional levels of 2,000 calories per person per day for its population. (A) Even though its per capita food supply hardly increased during (B) Even though its per capita food supply has hardly increased in (C) Despite its per capita food supply hardly increasing over (D) Despite there being hardly any increase in its per capita food supply during (E) Although there is hardly any increase in per capita food supply for 错选了E,答案是B。排除ABCD是因为代词its,前半句说了its,后半句没有第一时间解释its是指谁。尽管觉得E也有不妥之处,E的any increase应该是名词吧?副词hardly修饰名词也不对吧?麻烦老师讲解。

提问:

7.15/寂静:STUVW, 5个人, V和W中间必须隔一个人,求问共有几种组合? 我的想法是这样的A(3,3)*A(2,2)*C(3,1)=36种;思路如下:先把V+C(3,1)+W看成一个整体;可得:A(2,2)*C(3,1)种排法;然后5个人可分成三类,于是A(3,3)。不知道我的想法对不对,请老师解答。感激不尽!
