　　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.

　　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.

　　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.
