详解语法难点affect与effect的用法

学习啦在线学习网详解语法难点affect与effect的用法

学习啦在线学习网 　　下面是学习啦小编整理的一些关于 affect与effect的用法，希望对大家有帮助。

　　1.'by/in contrast'和'on the contrary'的用法

　　By contrast / In contrast

　　我经常在短作文和长作文里使用这2个短语。他们的用法完全相同。和however、on the other hand相似，它们用于介绍相反的观点或进行比较。By/In contrast可以用于句首，后面要加逗号。

　　Example

　　例如：

　　Unemployment rose in the UK. By contrast, the number of unemployed people in Canada fell.

　　On the contrary

学习啦在线学习网 　　I've never used this phrase in any of my IELTS lessons. It doesn't mean the same thing as "by / in contrast". We use "on the contrary" to deny that something is true, and to explain that the opposite is true.

　　我从未在我的雅思课中用过这个短语。它和by / in contrast的意思不同。我们用on the contrary来否定某事，并解释与之相反的事是真实的。

　　Example

　　例如：

　　- Person 2: "On the contrary, the hotel was great, but the airline lost my suitcase."
