1.固定宾语从句
仔细研究剑桥系列考官的范文，不难发现，小作文中常用的复合句其实就是宾语从句，定语从句和状语从句。
e.g. 举个栗子，在《剑8》的Test 2考官范文中的句话：
The charts show how much a UK school spent on different running costs in three separate years: 1981, 1991 and 2001.
还有《剑7》的Test 2范文中的后一段：
the graph shows how the consumption of chicken increased dramatically while the popularity...
《剑7》的Test 4的后一段：
it is clear that...
大家不难发现，宾语从句常用在开头，结尾或者两段过渡句的写作中。
2.翻新定语从句
定语从句是同学们复合句中用的普遍的，也是容易掌握的句式。但如果想要满足对于定语从句的出彩使用，同学们可以参考《剑9》的Test 2范文中第四段的后一句话：
e.g.《剑9》Test 2 This rise was particularly noticeable between 1990 and 2000, during which time the use of mobile phones tripled.
这里考官并没有用“常规”的which引导的定语从句，而是使用了“介词+关系词”的方式，使得句子变得高大上了许多。类似的用法在《剑5》的Test 1中后一段话也有出现。
可以看出比较容易操作的方式是在句子后出现时间的时候，使用during which或者by which这样的结构，可以将具体图表变化的趋势写出来，或者可以直接使用关系副词中指代时间的when。
e.g.《剑8》Test 2 This cost decreased to only 5% of total expenditure in 1991 but rose dramatically in 2001 when it represented 23% of the school budget.
3.巧用状语从句
e.g.《剑7》Test 2 Although it remained the least popular food, consumption levels were the most stable.
这里用了让步状语从句来表示位置低的线，那我们不难得出结论：在动态图中，表述大的数值或者高的柱，其实都可以使用让步状语从句。
比如这样一个句子Courses made up the largest proportion in factors that influenced students’ choice and its percentage decreased from 40% to 34%.
如果我们使用让步状语从句，就可以变成了：Although Courses made up the largest..., its percentage still decreased...这样，并列句就可以很好的转化成状语从句了。
e.g.《剑6》Test 3 This stage lasts for up to six weeks until the larva produces a cocoon of silk thread around itself.
时间状语从句是流程图中常用的句式，还有常用的连接词为while, since, when, after和before。
e.g.《剑5》Test 1While the figures for the Western countries grew to about 15% in around 1990, the figure for Japan dipped to only 2.5% for much of this period.
