The three pie charts below show the changes in annual spending by a particular UK school in 1981, 1991, and 2001.
Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The pies illustrate a particular school's expenses on five categories in three separate years in Britain.
「Max. + Min.」
Most apparently, compared with + insurance, which received least money, teachers’ salaries held the largest proportions in three separate years. // To be more specific, the year of 1991 witnessed that + the teaching staff received half of the whole school’s expenditure as their payment (非“機械式”地描述數據，而是寫出了“動感”，即：數據后體現出的facts). By marked contrast, a mere 2% and 3% of the whole overheads was allocated to insurance in 1981 and 1991 respectively.
「The rest three categories」
In 2001,（活用時間點加個定從，不要輕易丟了得分點）when the proportion was 15%, other staff’s salaries became smaller than in 1981 (28%) and in 1991 (22%). // Resources cost differently in the three years. Noticeably, one fifth of the school’s total spending was used in 1991, and the school allotted as much as a half of the total expenditure to the items in 2001. //（小作文也可以套路一下）The similar variation could be found in the spending on furniture and equipment: the respective proportions were 15% in 1981, 5% in 1991, and 23% in 2001.（年份跳躍，難以直接“增減”，詞窮了，直接偷個懶數據羅列一下也無妨。）
Overall, the school’s expenditure varied from category to category in three separate years.
In many countries, there is not enough recycling of waste materials (e.g. papers, glass, cans). What are the reasons and solutions?
<“縱向”的行文展開-先總寫后解釋 strong="" argument=""> Primarily, individuals should be blamed. → <細節解釋一下為什么>This is mainly because they do not realize the importance ofnot leaving a footprint on earth, thus failing to form the habit of getting daily refuses properly recycled. → <必要的elaboration一定不能省>With the economic growth advancing rapidly in thisconsumption society, they have easier access to a wider scope of commodities, under which circumstance they may just <呼應前面的消費型社會，在這其中“丟棄”文化很盛行> throw away the worn ones instead of recycling the used materials such as household appliances.。
//Additionally, the lack of recycling facilities acts as a catalyst for such phenomenon. By this I mean,even if people have raised the awareness of preserving environment，it is quite difficult for them to get wastes recycled appropriately owing to the scarcity of recycle bins.
Considering the severity of this issue, two corresponding measures are in dire need. // <開始針對原因一寫措施一> Since most individuals are not so well-educated and not informed to handle with the waste items, the top priority is for local councils or related experts to give lectures on how to recycle waste materials properly. In this case, people can be aware that their daily behavior actually makes a marked difference to our environment, which can help preserve our Mother Nature. / <開始針對原因二寫措施二> Secondly, the tension of the issue can be eased by increasing the number of dustbins in public areas. In this case, thedisposal of waste materials becomes more accessible.
Since the reasons have been enumerated above, this issue, as a matter of fact, is never insoluble as long as the concerted actions are taken by both governments and individuals.
