19. The Iroquois were primarily planters, but supplementing their cultivation of maize, squash,and beans with ?shing and hunting. (A) but supplementing (B) and had supplemented (C) and even though they supplemented (D) although they supplemented (E) but with supplementing 我想问一下为什么A不行呢?答案上说supplementing的错,为什么?难道ing形式表达不了转折么?谢谢啊…… -- by 会员 tjtgzxs (2011/10/2 15:34:06)
根据og解释,从句意上分析,作者本意是强调前一分句的primarly, 从两句一个是primarly, 一个是supplementing,也能看出肯定强调的是主要的,而不是补充的,所以A选项的but表强转折是强调后面的意思,另外supplementing这个分词形式也是错的,即使but没有错,典型的转折平行, supplement 需与前一句的The I were planters 结构上保持一致,所以也应该是 they supplemented. 同时D选项,although 这个词强调的是前一分句,且后面的supplement的形式也对,所在为正确选项。 希望能帮助你啊! |
