重要的事情说三遍。

这是遍：不是线图，不可以当成线性概念来写。

The bar chart displays the popularity of four areas of study at a university. 不是线图，不可以当成线性概念来写（第二遍）。Two historical years (2008 and 2013) are investigated, and they are compared with a future year (2025). 

不是线图，不可以当成线性概念来写（第三遍）。

所以，笔者用单独一段写完过往所有（四个专业在两个过往的年份）。

In the two historical years, Biology, Engineering and Business weremarkedly more popular than History, and Engineering was the most desired field in 2013 with 6,000 applicants for it, and one of two most popular – the other is Biology – in 2008 with 4,000 applicants. It is also notable that applicants, in the year of 2013, wanted to study Business as much as they wanted to study Biology, and the numbers were both roughly 2,500. History, in both of the two past years, received merely fewer than 1,000 applications.

再单独一个段落纯粹写将来。

The year of 2025, according to the forecast, will see a changed pattern, particularly in the popularity of Biology and Business. It is predicted that these two realms will not receive more than 1,000 applications. Meanwhile, Engineering, with the projected number of 6,000 students aiming for it, will remain most popular, whereas the popularity of History will stay at a low level.

Overall, 不是线图，不可以当成线性概念来写（第四遍，因为可能三遍还不够）。the future pattern of how many students apply for the four areas is predicted to bevastly different from the past.
