如何使用介系詞

介系詞是描述單字之間關係的詞。介系詞能夠描述某物或某人的位置。

例句
The cup is on the table.

在上例中,介系詞“on”描述了杯子和桌子之間的關係。介系詞也能描述事件發生的時間和方式。

例句
I arrived before him.
例句
I arrived by bus.

在上例中,介系詞“before”描述的是“I”何時到達的時間與“him”有關,而介系詞“by”表示的是乘坐“bus”是到達的方式。

例句
The purpose of this study was to develop a highly heat resistant composite with a carbon fiber base.
例句
A book is for reading.

用介系詞結束句子

人們通常認為句子不能以介系詞結尾。這種假設其實不對。有時,在句末不使用介系詞會造成句子不夠自然流暢。

不自然
Is this the movie about which you told me?
自然
Is this the movie you told me about?

另外,把介系詞移到句子中靠前的位置能夠使句子顯得更加正式。

非正式
What journal was your last paper published in?
正式
In which journal was your last paper published?

在上例中,這兩個句子都正確,但後一句比前一句更加正式。因此,在學術寫作中,介系詞很少用在句子末尾。

非正式
This is a topic we previously wrote about.
正式
This is a topic that we discussed in a previous paper.

當把介系詞移到句子中靠前的位置時,需要注意去掉在句子末尾的介系詞。

錯誤
In which journal was your last paper published in?
正確
What journal was your last paper published in?
In which journal was your last paper published?

避免不必要的介系詞

像形容詞一樣,介系詞也經常被濫用,即使母語是英語的作者也如此。濫用介系詞包括兩種情況。第一種情況是在句子中錯誤使用介系詞。

錯誤
Where is the other student at?
正確
Where is the other student?

在上例中,介系詞“at”在語法上是多餘和錯誤的。 第二種情況是句子結構的寫法不好,使用了太多介系詞。

例句
An understanding of gold composites is necessary for any company in the semiconductor industry at this time.

這種句子最好在結構上重寫,使得無需使用那麼多介系詞,示例如下。

例句
Understanding gold composites is necessary for companies in the semiconductor industry.
