But the prime reason is perhaps that CET4 as a more difficult test than Precto3 is a challenge and it is this challenge that appeals to me. As a result, I am doing my CET4 now. No doubt, besides providing grade, it also lets me know what I need to spend more time on, and helps make my English permanent. Therefore, I would make more efforts to achieve success in it.“圖表模塊”Pattern1: 揭示根源及潛在問題的圖 As indicated by the figures (data) given in the picture (graph), it is obvious that X fell/rose significantly (greatly/sharply/steadily//climbed) from ( 數(shù)字）in（時(shí)間）to ( 數(shù)字）in （時(shí)間).

It can also be seen, as a sharp contrast, that the infant mortality has dropped steeply by 15%, from 250 deaths per 1000 births to about 100 deaths per 1000 during the same period. There are several causes contributing to the development shown in the graph. Among other things, the rapid advance in medical science has made it possible to cure a lot of originally incurable diseases and save the life of millions of newborns who might well have been choked or killed before their birth. Besides, the general improvement of ordinary people’s living standard aroused their interest in healthy foods and healthy activities.
