1.数值大与小的比较
在同时期比较两个事物的数值时,例如,表达A大B小,常常用表示对比的连词while将两句话连接起来,并且在while后面的B事物前加上much more或者much less一类的比较级,以突出B的小,跟A做对比。例如:
Lamb and chicken were eaten in similar quantities (around150grams), while much less fish was consumed (justover50grams).
(剑七Test2)
或者B事物前加用only来表示数值很小,又例如:
…nuclear power,..., had developed into the main source, producing almost 75% of electricity, at 126 units, while coal and oil together produced only 50 units.
(剑七Test4)
变化幅度的大小也能够被类似的句式表达,比如:
The consumption of fish also declined, but much less significantly to just below 50 grams,

2.增长与减少的比较
这也是段落内部十分常见的对比方式。先描述A下降或上升了,然后用while或者类似的连词连接后面的B上升或下降了;同时,这种比较也适用于段落之间,比如正文的一个主体段写A,B和C都上升了,下一个主体段写D下降了。需要注意的是,如果是段落间的比较,则不适合用while,而应该用In contrast, Conversely, on the other hand一类表示意群对比的句首词。例如:
The consumption of chicken, on the other hand, showed an upward trend,…
(剑七Test2,作为一段的首句,说明前面一段写的是其他几种肉类的消费量都下降了。)
段落内部的比较还是可以放心大胆的用while,例如:
However, while the figures for the Western countries grew to about 15% in around 1990, the figure for Japan dippedtoonly 2.5% for much of this period,….

从上面的几个例子中大家可以看到,这两个比较是雅思小作文中最常出现、也是最重要的类型,作为雅思小作文的必备技巧,大家在备考的时候一定要掌握,这样才能在考试的时候更加得心应手的应对,取得好的成绩。
