The graph illustrates the numbers of participants in film club, martial arts, amateur dramatics, table tennis, and musical performances at a social centre in Melbourne during the period from 2000 to 2020.

As seen, the numbers of film club and martial arts participants in the beginning and end of the period remained similar, despite experiencing some fluctuations. Specifically, in 2000, the film club had by far the highest number of participants at 64, and its participation was relatively stable, reaching around 65 participants by 2020. Meanwhile, martial arts started with about 36 participants in 2000, but that figure showed a decline, dropping to around 30 in 2005 before increasing again to 36 in 2020.

On the other hand, musical performances and table tennis saw growths in their participation rates. Notably, musical performances had the fewest participants until 2010, with none before 2005 and only 12 in 2010. However, joiners in that activity increased gradually to around 20 in 2020. Likewise, involvement in tennis climbed slightly from around 18 participants initially to around 20 in 2010, after which it surged to 55, surpassing martial arts’ participation rate, making tennis the second most popular activity in the centre. In contrast, although the number of amateur dramatics participants rose slightly from 26 in 2000 to about 28 in 2005, it dropped constantly to approximately 8 in 2020.

Overall, the film club maintained the highest and most stable participation rate throughout the period, while table tennis saw the most significant upturn in participants.

真題解析：

本題是《劍19》test 1，本題的難點在于項目種類多（有5組之多），這也造成考生在描寫圖表數據時很難分段。本題采用訓練營和《細說雅思寫作》里講到的常用分段思路——按照變化趨勢分段，將變化趨勢相似的film club和martial arts分為一組，剩下的3個項目分為一組。

按照我一貫所強調的，動態圖要寫：1. 數據大小的比較與描寫；2. 數據變化的比較與描寫，我用不同顏色將這些內容標記出來便于考生整理歸納。紫色是數據大小比較，藍色是變化趨勢比較，褐色是變化趨勢的描寫，嫩綠色是introduction概括名詞具體化，天藍色是上下文銜接語，紅色是數據描寫。

范文中給出了多種數據描寫技巧，例如：with復合結構（with none before 2005 and only 10 in 2010 ），非謂語動詞做狀語（surpassing martial arts’ participation rate, making tennis the second most popular activity in the centre），以及多種比較句型（despite experiencing some fluctuations, but that figure showed a decline, dropping to around 20 in 2010 before increasing again to 40 in 2020, after which it surged to 55 和 although the number of amateur dramatics participants rose slightly from 26 in 2000 to about 28 in 2005）等高分句型值得考生掌握。
