VOA名师答疑2024--Learning Prepositions

（单词翻译）

Hello! This week on Ask a Teacher, we answer a question from Kelvin in Ghana about the usage¹ of prepositions³ in English.

Question

Dear teacher,

Please, I would like to know more about prepositions.

Thank you,

Kelvin

Answer

I'm happy to answer this question, Kelvin.

Prepositions are those small words that give additional⁴ information about nouns⁵, such as direction, time, location, and possession.

We can put prepositions into two large groups. In the first group, prepositions tell us about direction, location, time, and relations between people or things. These details are what people first learn when they study prepositions in English. Just a few examples of location and time include:

on the table.

under the table.

by nine in the morning.

at night.

Some examples that show relations between people include:

A friend of mine.

I worked with him.

I did it for you.

Prepositions in common expressions

The second large group includes common expressions where the preposition² sometimes has a less exact meaning. That is why knowing which preposition to use with these expressions becomes more difficult.

Consider the following two examples. The first is used in British English, the second in American English:

This house is different to the one I used to live in.

This house is different from the one I used to live in.

The two examples mean the same thing. And there is no clear reason why we should use one preposition instead of the other.

Here is another expression where we use one preposition instead of another. We often say:

The news took me by surprise.

But we never say:

The news took me with surprise.

However, notice that changing the preposition "by" to the preposition "with" does not appear to change the meaning of this expression.

To someone learning⁶ English, one preposition might seem as good a choice as any other for this expression. That is why it is easy to make mistakes and sometimes difficult to remember the correct preposition to use.

So, how can you remember what preposition to use with such expressions?

Do not try to learn the expression separately from the preposition, and then go back and put the preposition in your memory.

Instead, try to hear and remember the entire expression as one phrase instead of several words.

Just as we put numbers into groups of three or four to remember phone numbers, try to think of an expression and its preposition together as one group.
