John Larrysson Column: Prepositions - in ten? at ten?
文章日期:2012年2月8日

Many people in Hong Kong have trouble with English prepositions. Prepositions are those extra grammar words in sentences that tell you things like how, when and where. English teachers like to explain that they make sense and so should be easy. A common example is that we ride 'in a car' not 'on a car'. A horse is ridden 'on' and not 'in'. That sounds easy; we can picture someone sitting on top of a car as wrong and riding in a horse would be uncomfortable.

The problem is that they are not always so easy. We travel 'on' an airplane/ a ship/ a train, but if you picture sitting on top of them it would seem to be wrong. Some prepositions just have to be memorised.

In many cases even when a mistake is made it is usually obvious what you meant. So sometimes errors are not too bad.

The purpose of language is to communicate and there are times when mistakes cause confusion. Errors that sound silly are bad, but when the meaning has been changed the result can be troublesome. If your boss wants your report in ten minutes, that is very different from wanting it at ten. "At ten", means at ten o'clock.

These prepositions create different meanings:

In ten, at ten, on ten, since ten, until ten, for ten, by ten.

I want it in ten. (minutes from now)

I want it at ten. (10:00 am or pm)

I want it on the tenth. (day of the month)

I have been doing it since ten. (The time period from 10:00 o'clock until now)

I will wait until ten. (The time period from now until 10:00 o'clock)

I will be on vacation for ten days.

I want it by the tenth. (day of the month)

Hong Kong Chinese People often confuse some prepositions of place for historical reasons. We commonly say that we are going 'to China', when we are already 'in' China. A few years ago it was correct, but no longer. Hong Kong is now in China. When we go home to our flat we can't say we are 'going to Hong Kong' even though our flat is in Hong Kong, because we are also in Hong Kong when we speak. A person going 'to' a place must start from outside that place. This outline should put the problems with prepositions in perspective.
