雅思小作文中怎样表达变化

英语自学网

在雅思小作文写作的过程中准确的表达变化是非常重要的一个项目，新东方网雅思频道建议大家在备考中可以组合一些简单句来进行，这样可以减轻备考的负担，也可以在考试中有更好的发挥。那么我们可以应用哪些简单句呢?
        1.主+谓
        此结构是描写数据动态变化的首选句型结构，需注意的是主语必须是“数据”比如number, figure, percentage等，不能是其他名词，而谓语动词也只能是不及物动词比如increase, drop等。下面我们来看几个例子：
        I.The number of visitors increased sharply between 1995 and 2005 inChina.
        II.The percentage of people aged 15-46 dropped slightly by 10% during the 40 years.
        III.The figure for college C rose gradually to 30,000 in2002.
        IV.The number of aged people over 65 dropped slightly from 1960-1980.
        V.The number of aged people over 65 fluctuated between 1 million and 1.2 million from 1940-1950.
        2.主+谓+宾
        此句型结构的特点在于谓语动词必须是及物动词，比如witness, see等，宾语位置要用表示动态变化的名词比如growth, reduction等，在主语位置上可以仍旧为数据，也可以是地点或者时间段。它对于用主谓结构表达的句子可以作同义转换，比如：
        I.The number of visitors saw a sharp increase between 1995 and 2005 inChina.
        II.China witnessed a sharp increase in the number of visitors between 1995 and 2005.
        III.The years between 1995 and 2005 saw a sharp increase in the number of visitors in China.
        3.there + be
        此简单句型一般用于对于上述两种动态数据描写句型进行同义转换，be动词的时态一定要根据数据的时间来改变，否则很容易出错：
        I.There was an increase in the visits from about 12 to 53 million from 1979 to 1999.
        II.There was a sharp rise in the number of visitors between 1995 and 2005 inChina.
        III.There was a slight decline in the number of aged people over 65 from 1960-1980.
        IV.There was a fluctuation between 1 million and 1.2 million from 1940-1950.
