一，开头，也就是第一部分可以这么写。
我们说图表告诉我们XXX, 用哪个词？很多同学说
tell, show, illustrate(展示), reveal, reflect
1. As is shown by the graph/in the table...
2. From the table, we can see clearly that...
3. It can be concluded from the table that …
接下来就是对于趋势的描写：
数据变化的趋势莫过于上升和下降了
表示上升的词语: rise, go up, increase, boom, rocket，shoot up
表示下降的词语: fall, drop, come down, decrease(vi), reduce(vt), on the decline,
注意由于reduce是一个及物动词，所以要用be reduced这个词组
下面给大家补充的是修饰这些上升下降的词语
快: Quickly,
Rapidly,
dramatically戏剧性的， sharply急剧地，锐（增减），
慢:
slowly（缓慢地），gradually（逐渐地）
第一段就搞定了
As is shown by the graph, the vocabulary that one could remember dropped sharply from 100% to 33.7% at the first day. Then, they come a steady decline/ gradual fall /slow drop in the next 5 days.
二，开始写第二段话,分析原因（凡是原因有一句万能的话）
There are several reasons for such phenomenon. Physiological phenomenon
或 The reasons to explain this phenomenon can be listed as follows.
Three reasons contribute to such changes.
如果刚才那句话是白开水的话，这句话就是浓咖啡。
有同学说老师我不会写contribute to，那么lead to你总会写吧？result in, cause, be responsible for，create, give rise to, bring about都可以表示这个意思。
First…second…last (finally) (in addition)
各位在举祥林嫂的例子时不要说" sister Xianglin" ,因为语言是一个民族历史和文化传承的载体，不同的历史文化会产生不同的语言。比如说“阿庆嫂”“来福哥”你给外国人翻成“Sister Ahqing” “Brother Laifu”在西方的宗教文化背景中，听上去像神职人员或教徒之间的称谓。
阿Q精神， 背单词时要有祥林嫂的精神
最后一句写一个总结，形成总——分——总的结构。
Hence/Therefore, all these reasons result in such phenomenon.
千万千万不要使用重复的词语，如果避免不了重复，那你还不如不写这句话。
三，我们再看第三段: 提出解决方法,发表个人建议
My suggestions to solve the problem are as follows.
For one thing,... For another,... In addition/Moreover/Furthermore/What is more,...
On one hand…on the other hand…moreover
最后我们可以通过对图表的描述，说明和议论，最后可以发出呼声和呐喊。可以引用名人名言（当然可以自编），例如：
One great person once remarked…有一位伟人曾经说过 …
One of our ancient philosophers said…有位古代的哲人曾经说过…
One of the greatest English teacher in my life once said," Repeat is the best teacher"
