数据(data)、趋势(trend)、比较(comparison & contrast)、结构(structure)是一篇好的雅思小作文必备的4大核心要素。其中,趋势(trend)是指数据随着时间的变化而变化,主要表现为上升、下降、不变或波动等。
在对图表中的数据进行趋势描述时,必须掌握如下2个关键的核心句型:
sth increased sharpy. 剧烈上升
There was a sharp increase in sth. 剧烈上升上述2个句型可以相互转换。第1句使用“动词搭配副词”;第2句话使用“形容词搭配名词”。句中的increase可以换成任何表示趋势的词汇,例如rise, decrease, fall;sharply可以换成 slightly 或dramatically等。
描述趋势的动词和副词,基本上都有对应的名词和形容词,例如:
increase(动词)- increased(过去式) - increased(过去分词)
an increase(名词)
rise(动词)- rose(过去式) - risen(过去分词)
a rise(名词)
decrease(动词)- decreased(过去式) - decreased(过去分词)
a decrease(名词)
fall(动词)- fell(过去式) - fallen(过去分词)
a fall(名词)
sharp(形容词) - sharply(副词) - 含义:剧烈的
dramatic(形容词) - dramatically(副词) - 含义:剧烈的
slight(形容词) - slightly(副词) - 含义:轻微的
因此,上述的2个基本句型可以变换如下:
sth decreased slightly.
sth increased dramatically.
There was a slight increase in sth.
There was a dramatic fall in sth.
......下面,我们用2个具体的例子来应用这2个句型。
针对上面的线形图,我们可以将上述2个句型具体化如下:
The annual spending on cell phone services increased dramatically to around 750 dollars in 2010.
There was a dramatic increase in the annual spending on cell phone to around 750 dollars in 2010.可以说,在雅思图表英语作文中,所有与趋势描述有关的句型,都来自这2个句型。例如下面的并列句:
The percentage of males rose to 45% in 2014 and continued to increase to 48% in 2016.
