概括几个方面之间的关系，比如最旧的也是里程最多的，运送乘客也是最多的。
It is clear that the three oldest underground systems are larger and serve significantly more passengers than the newer systems
情形二：两个图，其中一个图有两个元素，比如age和purpose，两个都要提，并用while等衔接。另外一个图有一个元素，说出这个元素就还，比如更支持年轻人（虽然这个例子中40及以上的在上升，但是比起年轻人还是少）It is clear that the proportion of students who study for career purposes is far higher among the younger age groups, while the oldest students are more likely to study for interest. Employer support is more commonly given to younger students.
情形三：两个方面的最大值都集中在一个东西上，两个方面的最小值都在一个东西上。It is clear that the most incidents and injuries took place on demand-response vehicles. By contrast, commuter rail services recorded by far the lowest figures. 
情形四：有个总数特别大的值。内部的三个方面整体很均匀。先说最大的是谁，然后说每个国家的三个方面都非常相似。 It is clear that the USA is by far the most successful Olympic medal winning nation. It is also noticeable that the figures for gold, silver and bronze medals won by any particular country tend to be fairly similar. 
情形五：某个维度每个国家都最大。某个维度每个国家都最小。
It is clear that the largest proportion of consumer spending in each country went on food,drinks and tobacco. On the other hand, the leisure/education category has the lowest percentages in the table.
情形六：一共三个国家，其中两个国家某方面都是最大的。相反，另一个国家某方面是最大的。
It is clear that in both the UK and Sweden,the majority of dangerous waste products are buried underground. By contrast, most hazardous materials in the Republic of Korea are recycled. 
情形七：总数最大是谁，可以说成某个国家的总数多于另外两个国家。所有国家在某两个维度上都高。
Overall, the total spending of students in country A was higher than the expenditure of students in countries B and C. In all the countries, students spent the highest proportion of their budget on accommodation and food.
情形八：两幅图。其中一幅图是说全世界，一幅图说了三个洲。这里说了某个洲整体土地退化最严重，说了最大值，然后说了土地退化的最重要的两个原因是什么。这里没有再说全世界范围土地退化的原因，因为容易重合，毕竟都是讲土地退化的原因。
Overall, it is clear that Europe suffered more from farmland degradation than the other regions, and the main causes there were deforestation and over-cultivation.
情形九：这里出现了single, couple还有aged与否，带children与否。概括段就说了这三个维度的比较。
It is noticeable that levels of poverty were higher for single people than for couples, and people with children were more likely to be poor than those without. Poverty rates were considerably lower among elderly people.
情形十：男女性，还有五个维度。男性在五个里面的三个比女性多。某两个维度只有女性出现
It is clear that men enjoyed more hours of leisure time per week than women in three out of five categories（五个里面有三个）.However, only figures for women are shown in two categories, namely employed part-time and housewives.
