雅思小作文中怎么表达倍数与百分比

2021-05-18 07:21:00 编辑:无 浏览:(915次)

  在雅思写作小作文考试中,经常会要求各位考生根据图表去进行总结和描述图表中展示的信息,其中经常会出现一些表示倍数或者表示百分比的信息。接下来我们看看涉及到的相关考点,考生该如何去正确的表达,希望下面的分享可以为大家带来一些帮助。

  一、用“平级”或“比较级”表达倍数

  表达倍数时,既可以用“平级”,也可以用“比较级”。

  如:A楼的高度是B楼的三倍(A楼比B楼高两倍)。

  Building A is three times as tall as Building B. (平级)

  Building A is three times taller than Building B. (比较级)

  在倍数比较的句子中,常见的错误之一,是形容词与其所修饰的名词不搭配。

  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. ×

  在汉语里,可以用“多”和“少”来形容人口,于是很多人会用as many as。而句中的主语是population, 只可以用large/big/small来形容。

  二、百分数的表达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

  数词+percent+of+sth:后面谓语的单复数以percent后面跟接的主语(sth)为主

  例如:

  20 percent of the apples are eaten. (这里是复数的可数名词,所以用复数。)

  20 percent of the water is drunk.(这里是不可数名词,所以用单数。)

  ◆Percentage: portion or amount of something

  The percentage of +sth+ is:注意这里不管后面跟的是什么词,都用第三人称单数

  The percentage of the students is 46.

  The percentage of the water is 46.

  That was a high percentage.

  常见错误:

  Percent is only used after a number. If you are referring more generally to part of an amount, use percentage.

  Percent仅用在数字之后,如果更笼统表示数量中的一部分,可用percentage:

  A high percentage (不说percent) of the population was illiterate.

  绝大部分人口是文盲。

  三、时间介词at on in

  ◆at用在时间点前:

  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用在时间段,月份,年和季节前:

  The lecture is in the morning.

  The lecture is in June.

  The lecture is in 2004.

  The lecture is in winter.

  我们把这几个时间介词都放在一句话中:

  The lecture is at 7.00, in the morning, on Thursday, on 27 October, in 2004.
