雅思写作 如何简单描述折线图中的波动上升?

小作文中,当碰到一些变态级的复杂图时,我们也许需要描述两种同时发生的组合变化,比如上升的同时出现巨大波动。如何让一句话可以包涵更多相关信息。

如果想把图形的变化写清楚,需要尝试把同时发生的两种变化:波动 & 上升,同时体现出来。要描述同时发生的两段变化,我们就需要在英文句型中,找到可以表达同事发生的若干词汇和句型。如:

…, and/ but …

although ..., …

…, which …

with …, …

…, doing …

…, when ...

…, during which ...

我们尝试描述图中总和的数据的后半段,并且为了方便,对于主语、数据、时间都进行简化:

描述对象:total renewable energy consumption → total

描述内容:剧烈波动,总体呈上升

数据单位:Quadrillion Btu → QB

时间:1980 – 2010 (我们只描述后半段的波动上升)

数据:5 – 8

方法1:并列句 and/ but

这是最简单直接的方法。由于两个变化同时发生,我们可以写 and。又因为两种变化本质又不同,连词用but也合理。

The total increased from 5 qb to 8 qb between 1980 and 2010, and/ but it fluctuated violently for these three decades.

方法2:让步状语从句 although/ though/ despite

“although ”,与 “but ”两者意思相同,句子的侧重点不同罢了。

Although the total increased from 5 qb to 8 qb between 1980 and 2010, it fluctuated violently for these three decades.

Despite some violent fluctuations, the total increased from 5 qb to 8 qb between 1980 and 2010.

方法3:定语从句 which

正好咱们这里要描述的波动 & 上升,都是针对同一个对象 total 的,那么,我们正好可以把其中一个作为主句,另一个用定语从句放在描述对象后面就行了。

An increase from 5 qb to 8 qb can be seen in the total, which fluctuated violently for these three decades.

Some violent fluctuations were seen in the total, which increased from 5 qb to8 qb between 1980 and 2010

方法4:With 结构

两种可能的处理方法,一种是 with 后面加名词,一种可以加自带主语的分词结构。

The total fluctuated violently between 1980 and 2010, with an increase from 5 qbto 8 qb for these three decades.

The total fluctuated violently between 1980 and 2010, with the figure increasing from 5 qb to 8 qb for these three decades.

写分词结构的时候,doing 的主语其实就是total,所以不用赘述,用figure 替换即可。

方法5:现在分词 doing

一个变化做主句,另一个变成doing 放在主句后面。

The total fluctuated violently between 1980 and 2010, increasing from 5 qb to 8 qb for these three decades.

方法6:时间状语从句 when

两种需要合并描述的变化时间是一样的,于是 when 也是可行的:当数据上升的时候,它剧烈的波动了;当数据在剧烈波动的时候,整体上升了。

When the total increased from 5 qb to 8 qb between 1980 and 2010, it fluctuated violently for these three decades.

When the total fluctuated violently between 1980 and 2010, it increased from 5 qb to 8 qb for these three decades.

方法7:…, during which …

这里的which 指代的是前面描述的整个时间段,于是,中文理解为:在此期间。正好我们今天要处理的波动+上升,就是在其中一段变化期间,发生了另一个,所以,也是合理的。

The total fluctuated violently between 1980 and 2010, during which it increased from 5 qb to 8 qb for these three decades.

The total increased from 5 qb to 8 qb between1980 and 2010, during which it fluctuated violently for these three decades.
