2018年雅思寫作暖心推送第118篇：四個國家優質河水的變化對比（線圖）

The diagram indicates the proportion which river water in high quality represented(數據是百分比的圖形的固定改寫模式) and how it is expected to change（圖形中出現將來的固定句式） in four countries during the two decades from 1995.

When it comes to Country A, the percentage of good quality river water celebrated（好的趨勢表達時專用=embrace/be blessed with） a slight increase from 96% to 98% in the first five years, and then almost restored itself to the original level(回到起點的固定表達) in 2010, estimating that it will keep the same tendency to 95% until 2015.

In terms of Country B and C, their starting points maintained the same（比較起點時用，比較近的時候可以說：maintained extremely close） at 93%. Compared with a constant climb to 97% in Country B over the whole period, a sharp decline of 8% in Country C can be witnessed between 1995 and 2000, followed by a recovery(恢復趨勢的另一種表達，部分恢復是：a partial recovery), outstripping(超越，可以寫交叉點用) its initial level, accounting for the same rate as Country A in the end.

Clearly, the worst river water in quality was in Country D where its original and final ratio was and will be nearly 85%. In addition, its ratio undergoes an almost completely opposite movement to（相反趨勢） Country C. It is worth mentioning that its river quality was superior to（優於） Country C with 90% over the year of 2000.

Seen from the diagram, the quality of good river water in Country A and B keeps comparatively stable. By contrast, that in the other two countries differs largely（相差很大） during the given time.
