雅思小作文柱图分析

在小作文中，除了线图，柱状图考得很频繁。常以竖柱状图或横柱状图出现。通常又可分为单柱和多柱，且经常配合在组合图形里考察。今天我们就来对柱图进行详细的分析，特别是给大家列出了动态和静态两种写法：

1）如果横轴有明显的时间推移的话，烤鸭们应连接柱子顶点，重在描述柱子的升降起伏，写法类似于线状图。2）如果无时间推移，则写法和饼状图一样。即按照各比较对象所占比例的高低写，同时要注意各所占比例之间的比较。

可以用到的词汇有：

1.表示“占多少”的动词: account for，take up，make up，contribute to，have，represent　　
2.表示“最高级”和 “比较级”: 第一/最小 the largest/biggest proportion of, 第二 the second/next largest/expensive(+ 形容词的最高级), 第三 followed closely by, 最低/最小 the smallest percent of all
3.表示“相同比例”: 即在饼状图中遇到了比例相同或者差不多的饼，如有A B两个比较对象。A accounts for the same percentage as B/The proportion of A is as high as B/ A and B contributed equally/evenly to (all )

解题关键

在观察柱形图的时候首先要留意横轴的数据，若横轴为时间轴或者是年龄趋势，那么我们在主体段写作时候的基本思路就为从左到右；若横轴数据为具体专有名词诸如地点，交通工具等时，主体段的写作思路就可能是按照柱形的长度排列。

审题时要注意看好横纵坐标分别代表什么，以及时间单位。
把柱图当线图看，切入点是描述趋势。
写法：横坐标是时间的，按时间发展顺序对对象的整体趋势进行对比。无时间的，可根据量的大小多少进行对比。

题1：The charts below give information about USA marriage and divorce rates between 1970 and 2000, and the marital status of adult Americans in two of the years. 

Displayed in the first bar chart are data about marriage and divorce rates in the U.S. between 1970 and 2000 while the second bar chart demonstrates the marital status of adult Americans in 1970 and 2000.

According to the first bar chart, the marriage rate was consistently higher than the divorce rate over the thirty-year period. In 1970 the number of marriages stood at 2.5 million whilst that of divorce was 1 million. Over the next decade, that of marriages remained stable whereas that of divorces increased to 1.4 million over the same period. Then the following twenty years saw a gradual fall to 2 million in the number of marriages. Similarly, there was also a downward trend in that of divorces, reaching 1.4 million in 1990 and ending at 1 million in 2000.动态写法

The second bar chart clearly shows that married people accounted for the greatest proportion of the adult American population in both 1970 and 2000 (70% and 59% respectively). As for other categories, the percentage of Americans adults who were never married was 14% in 1970 and 20% in 2000. By contrast, people who were widowed represented 8% of the population in 1970 and 6% in 2000. It is particularly noticeable that divorced couples only constituted 2% of the entire population in 1970 but in 2000, the figure amounted to 9%, a 4.5 times increase. 静态写法

Therefore, it can be clearly seen from the charts that the USA marriage rates were substantially higher than the divorce rates over the three decades and married population made up the largest proportion of the whole population in both 1970 and 2000.
