詳解語法難點affect與effect的用法

　　下面是學習啦小編整理的一些關(guān)于 affect與effect的用法，希望對大家有幫助。

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

　　By contrast / In contrast

　　我經(jīng)常在短作文和長作文里使用這2個短語。他們的用法完全相同。和however、on the other hand相似，它們用于介紹相反的觀點或進行比較。By/In contrast可以用于句首，后面要加逗號。

　　Example

　　例如：

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

　　On the contrary

　　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.

　　我從未在我的雅思課中用過這個短語。它和by / in contrast的意思不同。我們用on the contrary來否定某事，并解釋與之相反的事是真實的。

　　Example

　　例如：

　　- Person 1: "You had some problems with your hotel, didn't you?"

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

　　2. affect和effect的用法

　　"Affect" is a verb. Don't write "affect on".

　　Affect是動詞。不要用affect on。

　　Smoking affects your health. (錯誤：smoking affects on your health)

　　The Internet is affecting our way of life.

　　Children are affected by what they see on television.

　　"Effect" is a noun. Do write "have an effect on".

　　Effect是名詞?？梢杂胔ave an effect on。

　　Smoking has a harmful effect on your health.

　　The Internet is having a significant effect on our way of life.

　　Television can have a negative effect on children.
