下面的图表提供了2000年也门和意大利人口年龄和2050年预测的信息。

雅思作文范文如下：

The charts show the populations of Italy and Yemen in 2000 and their predicted populations in 2050, broken down by age range and expressed as percentages of the whole national population.

In 2000, children aged under 14 years old were the largest group in Yemen, representing 50.1% of the whole population. People between 15 and 59 years old accounted for 46.3%, while the percentage of older people (60 years old and above) was very small, at only 3.6%. In 2050, the 15-to-59-year-old group is predicted to be the largest of the three, accounting for 57.3%, when the seniors and younger children will constitute 37.0% and 5.7% respectively.

In Italy, younger children (0-14 years old) only constituted 14.3% in 2000, while the elderly represented a larger percentage (24.1%). The rest of the population (61.6%) were all aged between 15 and 59 years old. This age group is projected to almost equal the oldest one (42.3%) in 2050, accounting then for 46.2%. The remainder (11.5%) will be younger children.

In sum, the largest groups of both Yemenis and Italians are expected to remain between 15 and 59 years old.

题目及作文范文分析：

也门和意大利两国“0-14岁”，“15-59岁”和“60岁及以上”人口比例，2000年和2050年的数据。

按国家(横着)还是时间(竖着)写?

本质上来讲，两种都是可行的，但是强烈推荐考官的写法。这篇文章没有考官范文，但是剑桥雅思7 Test 4和这个题目如出一辙，就是按国家(横着)来写的。所以，这篇范文也是依据考官采用的结构，按国家来写的。

是否要写趋势?

看得出，这是一幅动态图，因为某个年龄段的人口比例随着时间变化。假如考官范文没有写趋势，你会写吗?同意建议，按照考官的做法，不写。所以，这是“当做静态图来写的动态图”。

文章结构?

两个主体段，一个写“也门”，一个写“意大利”;在每一个主体段内，前半部分写“2000年”，后半部分写“2050年”(标准的剑桥雅思7 Test 4考官范文的结构)。

时态?

描述2000年数据时用一般过去时，描述2050年数据时用一般将来时或者表示预测的词(predict, expect, project)。

通过以上分析，同学们知道改如何写这个题目了吧，上海新航道小编建议大家平时一定要多练习，多学习雅思写作相关的分析，相信对大家的雅思学习会有不少的帮助。
