　　Possible version:
　　The diagram shows us the comparison of English materials purchase made by the senior students in our school in the early 1990s and in 2005. In 2005 there were more new choices for students, like Internet (10%) and CD/DVD (28%). While in the early 1990s there were only tapes (33%) and reference books (67%). At the same time, the average expenditure on English materials has increased from 60 yuan in the early 1990s to 210 yuan in 2005. From these, we learn that there are more choices of materials on English learning and that students spend more money on them.
　　Some reasons can explain this (phenomenon). First, many students realize the importance of learning English. English is widely used all over the world. Second, since China entered WTO, learning English has become more popular. Third,as science and technology have been developing so fast / with the development of science and technology, these latest English learning facilities have already been proved far more useful and effective than traditional books.
