雅思写作动态图应该怎么写
有时间推移变化的图我们通常叫做动态图。曲线图都是动态图,但是对于表格图,饼图和柱图却有动态和静态之分。对于大多数的动态图我们都可以大致当作线图来处理。动态图重点在数字变化的表达上,利用主语句型的不同和衔接关联词来展开。写好动态图的基础是要准备好三个方面:
1.解题思路
1)表格题的动态题解题思路大致可以分为四步:①先相减(年份大的减小的);②后分类(上升一类,下降一类);③挑出极值(非常大值);④挑选数值(倍数关系,变化明显的数值);
2)线图的解题思路大致分为两种:种:①按整条线来写(可以把相同趋势的线放在一起,也可把相反趋势的线拿来做对比);②挑选重要信息(整体趋势,起点,重点,点,点);③整体作比较。第二种:①按时间区间来写(横轴对上去有共同拐点或交点的分为一段);②对比着写(强调交点,拐点,点,点);
3)动态柱图解题思路:把各个柱子的顶点连起来就是几条线,所以按线图方式处理;
4)动态饼图解题思路:把每种颜色看做一条线,可把相同相反的颜色放在一起写,很多时候也可以把占的比例非常大的单独写一部分。
2.基础替换词汇
1)趋势词汇
上升动词类:increase,rise,grow,jump,surge,shoot up,soar
下降动词类:decrease,decline,fall down,drop,sink,dip
波动动词类:fluctuate
持平动词类:remain the same,stabilize,remain stable,remain constant
修饰动词的副词:slightly轻微地,slowly缓慢地,gradually逐渐地,steadily稳定地,rapidly迅速地,moderately温和地,轻微地,significantly明显地,sharply明显地,dramatically急剧地,drastically急剧地
上升名词类:increase,rise,growth,jump,surge
下降名词类:decrease,decline,fall,reduction,drop
波动名词类:fluctuation
修饰名词的形容词:slight,slow,gradual,steady,rapid,moderate,significant,sharp,dramatic,drastic

2)极值类词汇和表达
点:reach the peak/top/highest point
Increase to the peak/top/highest point(所有上升类的动词都可以替换掉increase)
点:reach the bottom/lowest point
drop to the bottom/lowest point(所有下降类的动词都可以替换掉drop)
占了:occupy/make up/take up/account for/represent/constitute
3)倍数的表达方式
Double是两倍/大一倍
Increase/decrease three times增长/减少了三倍
4)大约的表达方式
Approximately/About/around+数字
3.常用的小作文的趋势句式表达
句式一:变化主体/图画中主体+趋势动词+副词+数值+时间区间
Eg:The number of aged people over 65 increased significantly from 1 million in 1940 to 1.2 million in 2000.
句式二:There be+形容词+表示趋势的名词+in+变化的主体+时间区间
Eg:There was a significant increase in the number of aged people over 65 from 1 million in 1940 to 1.2million in 2000.
句式三:时间+see/experience/witness+表示趋势的名词+in+变化的主体+数值
Eg:The period from 1940 to 2000 saw an upward trend in the number of aged people over 65 from 1 million to 1.2 million.
句式四:表示趋势的名词+be+seen/experienced/witnessed+in+变化的主体+时间
Eg:An upward trend was seen in the number of aged people over 65 from 1 million in 1940 to 1.2million in 2000.
