英语写作中常见的“转折”小结 (1) 一般意义上的“转折”：but, yet, however, nevertheless(nonetheless), though 首先，我们要注意以上四个词当表达“转折”时的词性不同But, yet是连词，however, nevertheless(nonetheless)和though是副词 其次，这四个词的用法和表意也是有差别的But和yet是连词，因此其用法应该是：A句，but B句. but的“转折”语气最为强烈however和nevertheless(nonetheless)是副词，因此其用法应该是：A句. However(Nevertheless/Nonetheless), B句. 而though虽然是副词，不过though的用法却是常置于句末，即A句. B句, though. 如：The return is uncertain, but/yet the investment is worth a try. The return is uncertain. However, the investment is worth a try. Nevertheless, the investment is worth a try. Nonetheless, the investment is worth a try. The return is uncertain. The investment is worth a try, though.(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。
其用法应该是：A句，while/ whereas B句. 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：A句. By contrast( On the other hand/ In comparison/ Conversely), B句.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：A句. On the contrary( Instead), B句. 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。
