The chart below shows percentages of people living by their own in five age groups in the UK between 1850 and 2000.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
虽然题目中的陈述是between 1850 and 2000，但是并不是线性概念，所以考核的是比较概念。
The four groups of bars are the illustrations of the percentage ofUK people living a solitary life in the four years of 1850, 1900, 1950, and 2000, and they are divided into five groups. ←不把题目中三个堆叠的介词短语重复，而是拆开。
Among the five age groups, two – the 26-40 group and the 55-65 group – ←故意设计成同位语的形式来丰富语法现象 stood out, 不要急着把句子停下来，后接(原因)状语从句，设计复合句： since the maximum (45 percent) and the minimum (approx. 3 percent) were in the two groups. It is also notable that the 26-40 group were more likely to liveindependently in the four years than the other groups. ←不要机械描述数据，而是陈述数据所体现出来的事实 The opposite was the case ←依托前文建立出来的语境来简化写作内容 with the 55-65 group except in the year of 2000.
The other three groups – the youngest group, the oldest group and the 41-55 group – did not have stark features. The four years witnessed a gradual growth in the percentage of people livingalone in the youngest group and a slow downtrend in the 41-55 group. In addition, the oldest group's mere 5 percent in the year of 1850 was also noteworthy.
Overall, in each of the four years, the likelihood of living alone varied from one age group to another, ←对应age group之间的比较，“同时不同项” and the more recent two years differ markedly from the two distant early years. ←对应年份之间的比较，即“同项不同时”
