雅思语法：比较中的相反比

这次为大带来上海谢老师为大整理的一些语法知识，希望对大有所帮助！
上次谈了下对比对象的一致性问题，此文将浅谈比较关系中表示相反比较的连接词on the other hand, unlike, 的用法问题。错在不清楚前后两句的关系以及比较对象的一致。举例说明。

1. 快餐食物的营养不如传统烹饪方式做出的食物。而且快餐食物对人们之间的纽带关系可能有很大影响。
误：On the one hand, fast food is not as nutritious as the food cooked in traditional ways. On the other hand, fast food might have a profound impact on the bond between people.
正：Fast food is not as nutritious as the food cooked in traditional ways. In addition, fast food might have a profound impact on the bond between people.
分析：两个句子都说快餐的坏处，不应该用“on the other hand”，应该换成not only....but also....；besides, what is more, moreover, in additional, additionally, furthermore.
其次，on the other hand 非常容易用错，大就那么随便一用，但就用错了，以为两者是属于并列递进关系，实际上两者是两个相反的事物和看法。
如：On the one hand, if the body doesn’t have enough cholesterol, we would not be able to survive. On the other hand, if the body has too much cholesterol, the excess begins to harden the arteries.这才是正确的用法。
再如：On the one hand, we would demonstrate that we could be good guides by safely guiding our blind partners around the campus.

2. 不像台湾多数看电影的人，盲人必须依赖声音，因为他们无法看字幕。
正： Unlike most Taiwan moviegoers, the blind must depend on the audio track because they can’t read the subtitles.
分析：要注意的是，Unlike A, B do....这个结构中，A和B是同类事物，
再如：Unlike more established industries,with clearly defined lines of competition, those of the Internet industry are blurred and indistinct, as competing companies one day maybe partners the next.
又如：Unlike the tiny tubes that convey nutrients to bone cells, which in mammals are arrayed in parallel lines, in birds the tubes form a random pattern.
