雅思描述线性

在雅思写作中，描述线性图表时，通常需要遵循以下结构和要点：

开头段落

首先描述数据的变化趋势，使用“先（上升/下降）后（下降/上升），之后便平稳”的句式。例如：“According to the data, the years from 2015 to 2017 saw a rise in the number of students, which was followed by a steady decrease over the next two years.”

峰值和低谷的描述

指出在某个时间点，数据达到了峰值或低谷。例如：“However, in 2019, the number of students reached a peak of 300, after which there was a noticeable decline.”

趋势相同的描述

如果图表中有两条或多条线，且这些线遵循相同的趋势，可以进行比较描述。例如：“The proportion of students studying abroad in 2015 and 2017 was similar, both showing an increasing trend.”

未来趋势的表述

可以根据图表数据预测未来的趋势，使用“is projected to”、“is expected to”或“is estimated to”等词汇。例如：“It is expected that the number of students will continue to decline in the coming years.”

波动的描述

如果图表中显示了数据的波动情况，可以使用“as can be seen from the graph”或“as shown in the figure”等句式进行描述。例如：“As can be seen from the graph, there has been a significant fluctuation in the sales figures over the past five years.”

注意时态

一般来说，描述过去的数据时，应使用一般过去时。例如：“The number of students increased from 200 to 250 between 2015 and 2017.”

通过以上结构和要点，可以清晰地描述线性图表中的数据变化，使文章结构完整、逻辑清晰。
