今天，苏州环球教育为大家准备了雅思阅读关键词：转折关系。在我们做雅思阅读的时候，需要特别注意雅思阅读关键词，这一类词往往会表述下一句话的重要性。

表转折

but， however， yet， in fact， on the other hand;

A， but B：否定A而肯定B，则A，B两部分内容是相反的。

例如：Computerized data storage and electronic mail were to have heralded the paper less office. But， contrary to expectations， paper consumption throughout the world shows no sign of abating .

解释：paper less 表示负向，则but后no sign of abating 表示正向，所以abating是表示负向的词。

总结：此种方法有利于在不认识单词的前提下读懂句子意思，很有帮助，但一定要练习，而且要敏感。

练习：The marginal costs of generating electricity from nuclear energy may be tiny， but ， as the technology now stands， huge and uncertain costs are involved in building the power stations， dealing with spent fuel， and decommissioning.
