(2) 表示“对比”含义的“转折”:
① while, whereas ② by(in) contrast, on the other hand, in comparison, conversely
首先,第①组的两个词都是连词,表示含有“对比”的转折。其用法应该 如:
American
consumers prefer white eggs, while/ whereas British buyers like brown eggs.
其次,第②组短语或词都是副词性的(短语是副词性短语),表示含有“对比”的转折。其用法应该是:
如:
American
consumers prefer white eggs. Conversely, British buyers like brown eggs. American
consumers prefer white eggs. By(In) contrast, British buyers like brown eggs.
American
consumers prefer white eggs. On the other hand, British buyers like brown eggs.
American
consumers prefer white eggs. In comparison, British buyers like brown eggs.
可见,上面“对比”的含义是两个事物在一个方面上的对比。
(3) 表示“相反”含义的
“转折”:on the contrary, instead
以上的短语或词都是副词性的,表示含有“相反”的转折。其用法应该是: 如:
He isn’t poor. On the contrary, he is a millionaire.
Instead, he is a millionaire.
显然,上面所说的“相反”的含义是一个事物的两个相反的方面。
