雅思數據類小作文主要包括：
Pie chart 餅狀圖
Line graph 曲線圖
Bar chart 柱狀圖
Table 表格圖
Combination 混合圖表
本文主要分析Bar chart數據類小作文的寫作技巧
Bar chart柱狀圖
考生在完成小作文時容易出現以下兩個問題：
一.是分不清楚動態圖與靜態圖的區別，即而找不到圖表中的有效數據，導致數據描寫過多寫成流水帳或是描寫數據過少無法完整表達整個表格內容；
二.是對於時間把握不準確，不知道重合入手，常常一不小心就超出20分鐘，導致小作文寫不完
小作文數據類別共分成兩種：靜態圖和動態圖。這不是由四種圖形（Table，Pie, Line, Bar）來決定的，而是由數據特徵來定。
如何判斷動態or靜態圖
在雅思考試中，線圖沒有靜態圖，一定是動態圖！
柱圖有動態也有靜態（常考動態變化）；
餅圖有動態有靜態（餅圖動、靜都會考）；
表格圖有動態也有靜態（常考靜態圖）
*主要是隨著時間的變化而變化的必是動態圖表，也是雅思考試趨勢中最常考的數據類小作文。

寫作題目：
The bar graph shows the global sales (in billions of dollars) of different types of digital games between 2000 and 2006.
Writing analysis：
首先來構思一下段落結構
For the task 1 report, I aim for 9 sentences
Writing structure：
· Introduction: 1 sentence
· Overview (summary): 2 sentences
· First 'details' paragraph: 3 sentences
· Second 'details' paragraph: 3 sentences
寫之前需要思考三件事：
- how you would paraphrase the question for your introduction如何在Introduction段複述問題
- what two things to include in your overview paragraph如何在Overview段總結兩點信息
- how to separate your description of details into two paragraphs如何將圖中的細節寫入兩個段落
Sample answer：
The bar chart compares the turnover in dollars from sales of video games for four different platforms, namely mobile phones, online, consoles and handheld devices, from 2000 to 2006.
It is clear that sales of games for three out of the four platforms rose each year, leading to a significant rise in total global turnover over the 7-year period. Sales figures for handheld games were at least twice as high as those for any other platform in almost every year.
In 2000, worldwide sales of handheld games stood at around $11 billion, while console games earned just under $6 billion. No figures are given for mobile or online games in that year. Over the next 3 years, sales of handheld video games rose by about $4 billion, but the figure for consoles decreased by $2 billion. Mobile phone and online games started to become popular, with sales reaching around $3 billion in 2003.
In 2006, sales of handheld, online and mobile games reached peaks of 17, 9 and 7 billion dollars respectively. By contrast, turnover from console games dropped to its lowest point, at around $2.5 billion.
