在雅思寫作中,倍數和百分比表達我們經常會使用到,那么,雅思寫作中的倍數和百分表應該怎么正確表達呢?
一、用“平級”或“比較級”表達倍數
表達倍數時,既可以用“平級”,也可以用“比較級”。
如:A樓的高度是B樓的三倍(A樓比B樓高兩倍)。
Building A is three times as tall as Building B. (平級)
Building A is three times taller than Building B. (比較級)
在倍數比較的句子中,常見的錯誤之一,是形容詞與其所修飾的名詞不搭配。
例如:
The population of China is five times as big as that of Pakistan. √
The population of China is five times as many as that of Pakistan. ×
在漢語里,可以用“多”和“少”來形容人口,于是很多人會用as many as。而句中的主語是population, 只可以用large/big/small來形容。
二、百分數的表達percent or percentage?
Percent : it is used to express proportions out of a hundred. Percent is always used with a number.
2 percent = 2%
percent = per centum
數詞+percent+of+sth:后面謂語的單復數以percent后面跟接的主語(sth)為主
例如:
20 percent of the apples are eaten. (這里是復數的可數名詞,所以用復數。)
20 percent of the water is drunk.(這里是不可數名詞,所以用單數。)
Percentage: portion or amount of something
The percentage of +sth+ is:注意這里不管后面跟的是什么詞,都用第三人稱單數
The percentage of the students is 46.
The percentage of the water is 46.
That was a high percentage.
常見錯誤:
Percent is only used after a number. If you are referring more generally to part of an amount, use percentage.
Percent僅用在數字之后,如果更籠統表示數量中的一部分,可用percentage:
A high percentage (不說percent) of the population was illiterate.
絕大部分人口是文盲。
三、時間介詞at on in
at用在時間點前:
The lecture is at 7.00.
on用在星期和日期前:
The lecture is on Thursday.
The lecture is on 27 October.
in用在時間段,月份,年和季節前:
The lecture is in the morning.
The lecture is in June.
The lecture is in 2004.
The lecture is in winter.
我們把這幾個時間介詞都放在一句話中:
The lecture is at 7.00, in the morning, on Thursday, on 27 October, in 2004.
以上就是雅思寫作倍數和百分比如何正確表達的相關內容,希望可以幫助到各位烤鴨的備考。
