第二类：柱状图
You should spend about 20 minutes on this task.
The charts below show the levels of participation in education and science in developing and industrialized countries in 1980 and 1990.Write a report a university lecturer describing the information shown below.
You should write at least 150 words.
model answer
1.The data shows the differences between developing and industrialized countries’ participation in education and science.
2.In terms of the number of years of schooling received, we see that the length of time people spend at school in industrialized countries was much greater at 8.5 years in 1980, compared to 2.5 years in developing countries. The gap was increased further in 1900 when the figures rose to 10.5 years and 3.5 years respectively.
3.We can see a similar pattern in the second graph, which shows that the number of people working as scientists and technicians in industrialized countries increased from 55 to 85 per 1,000 people between 1980 and 1990, while the number in developing countries went from 12 to 20.
4.Finally, the figures for spending on research and development show that industrialized countries more than doubled their spending, from $200bn to$420bn, while developing countries decreased theirs , from$75bn down to $25bn.
5.Overall we can see that not only are there very large differences between the two economies but that there gaps are widening.
分析
第一段：
1 The data shows the differences between developing and industrialized countries’ participation in education and science.
本句话依旧是对题干进行改写。Data是“数据”，相当于figure，number，percentage，proportion等。
第二段：
1 In terms of the number of years of schooling received, we see that the length of time people spend at school in industrialized countries was much greater at 8.5 years in 1980, compared to 2.5 years in developing countries.
这一段讨论第一组图，in terms of “在---方面”，引出所要讨论的东西。Received是过去分词做后置定语，we see that是常用句式。Compared to这里等同于compared with，与---比起来，相当于than。
2 The gap was increased further in 1900 when the figures rose to 10.5 years and 3.5 years respectively.
本句讨论两个柱状之间的差距。When引导状语从句，respectively是“分别地”，引出两组数据。
第三段：
1 We can see a similar pattern in the second graph, which shows that the number of people working as scientists and technicians in industrialized countries increased from 55 to 85 per 1,000 people between 1980 and 1990, while the number in developing countries went from 12 to 20.
We can see a similar pattern in the second graph是常用句型，which引导定语从句，which代替上文的整个句子或pattern这个名词，working是现在分词做后置定语，相当于 who work。While连接两个变化趋势相反的句子，作对比。
第五段：
1 Overall we can see that not only are there very large differences between the two economies but that there gaps are widening.
本 句依然是对总体趋势进行总结。That后面引导宾语从句。Not only --- but also不但而且。但同时作为that的宾语从句，又因为not only位于句首，而采用的倒装形式。Not only部分倒装are there，but also部分不倒装。
