   2、定语从句在图表中的运用

a. 数据图中的定语从句

The chart below shows the different levels of post-school qualification in Australia and the proportion of men and women who held them in 1999. (剑4 test 2)

例句1：The biggest gender difference is at the lowest post-school level, where 90% of those who held a skilled vocational diploma were men, compared with only 10% of women.(考官范文)

解析：这句话描述的低层次的文凭有着大的性别差异，90%的男生对10%的女生。这个可以拆分为两句来理解：

① The biggest gender difference is at the lowest post-school level.

② At the lowest post-school level, 90% of those who held a skilled vocational diploma were men, compared with only 10% of women.

其中The lowest post-school level可以作为一个抽象的地点，后面可以用关系副词where引导的定语从句来修饰，因此两句合并为The biggest gender difference is at the lowest post-school level, where 90% of those who held a skilled vocational diploma were men, compared with only 10% of women.
