1. 注意改写题目，1980到2000刚好二十年的时间，可以变为two decades.
3. 时态：过去时， 过去完成时；
6. 电话和书面档案（paper document）的使用时间下降；
The two pie charts give information about how much time was spent on activities in an American office over two decades （1980-2000）.
It is clear that in 1980， the most popular activities in the office was to phone other people， accounted for around 30%. Followed by using paper document， took up of 20% of the total percentage. Meanwhile， using computer was the lowest， only 2% of workers prefer this method. The ratio of face-to-face communication， meeting and other activities were similar， accounted for 14%， 19% and 15% respectively.
There had been some changes in the ways of working in 2000. One of the major differences was that people started to use email to communicate at work， which made up of 8%. Also， the time spent on computers took up the highest proportion （30%）. Meanwhile， holding meetings became the least popular for employees （6%）. The rate of paper document decreased by half， while the proportion of other activities and talking stayed constant.
Overall， it can be seen from the chart that instead of the traditional approach such as using paper document or face-to-face meetings， the use of technology had been adopted by many office workers.
Some people hold that we should spend amount of time and money on the protection of wild animals. Some people argue that they should be spent on human populations. To what extent do you agree or disagree ？
In these days， with some improper human activities such as hunting rare animals and the extinction of some endangered animals， there has been an intense debate about whether too many resources， including time and money， are allocated to preserve wild animals.
Proponents of this opinion may argue that human beings could have done more to safeguard wild animals from being extinct， so that less animals would have died out or diminished. After all， animals， as a key component of the whole food chain， exert a profound impact on the sustainability of an ecosystem. And every existent animal plays a crucial part in the nature balance. For example， the decrease of owls will lead to the multiplication of voles which are big eaters of crops. If the importance of protecting wildlife is underestimated， we human beings would be affected adversely in the end.
However， considering the allocation of the taxes levied from citizens， opponents believe that the government has more issues related to human rather than animals to give priority to， among which are education and technology， and there is no doubt that these two aspects are essential for human further development economically and environmentally； as a result the two industries give an impetus to the economic development of society， which will be conducive to the protection of wildlife in turn. As long as the government has the ability to construct more conservations for diverse animals， and the awareness of valuing animals is cultivated among all the residents， the better living environment can be guaranteed for all the wildlife.
From my perspective， considerable significance should be attached to the preservation of wildlife， but in the meantime， other crucial projects should not be ignored， especially education and technology.
