写作常识
一、图形种类及概述法：

泛指一份数据图表：a data graph/chart/diagram/illustration/table
饼图：pie chart
直方图或柱形图：bar chart / histogram
趋势曲线图：line chart / curve diagram
表格图：table
流程图或过程图：flow chart / sequence diagram
程序图：processing/procedures diagram

以下是一些较常用的描述用法
The table/chart diagram/graph shows (that)
According to the table/chart diagram/graph
As (is) shown in the table/chart diagram/graph
As can be seen from the table/chart/diagram/graph/figures,
figures/statistics shows (that)...
It can be seen from the figures/statistics
We can see from the figures/statistics
It is clear from the figures/statistics
It is apparent from the figures/statistics
table/chart/diagram/graph figures (that) ...
table/chart/diagram/graph shows/describes/illustrates how

阅卷考官经常是不会看那些图表的，因此文章必须逻辑清晰，如果描述得能令人在脑海里勾画出那个data chart，开篇的第一句话可以是一句高度概括性的introduction（当然开门见山直接描述也是一种写法）；这样做不仅使文章更趋于完美，而且可以达到凑字数的目的（但不要照抄题目，除非时间相当紧迫）。接下来另起一段开始进行描述（根据实际情况1-2段），这当中经常要连续使用非限定性定于从句，从而使得描述过程流畅、清晰。最后也可再另起一段进行简短的综述（并非必须）。上述的任何一个步骤都要遵循依据现有data进行客观描述的原则，任何推测性或议论性的内容写得再多、再精彩不仅不会加分，而且还会成为扣分的因素。

二、data的具体表达法

data在某一个时间段固定不变：fixed in time
在一系列的时间段中转变：changes over time
持续变化的data在不同情况下:
增加：increase / raise / rise / go up ...
减少：decrease / grow down / drop / fall ...
波动：fluctuate / rebound / undulate / wave ...
稳定：remain stable / stabilize / level off ...

最常用的两种表达法：
动词 + 副词形式（Verb+Adverb form）
形容词 + 名词形式（Adjective+Noun form）

1. Verb+Adverb form
The number of XXX
+increase/jump/rise/decrease/drop/fall/fluctuate...
+insignificantly/significantly/slightly/suddenly/rapidly/dramatically/sharply/steeply/steadily/gradually/slowly...
+from (第一时间) to (第二时间) / between (第一时间) and (第二时间)

2. Adjective+Noun form
There was a (very) sudden/rapid/dramatic/significant/sharp/steep/steady/gradual/slow/slight
+increase/jump/rise/decrease/drop/fall/fluctuation （注意：上述很多词不可用于修饰fluctuation）
+in the number of XXX from (第一时间) to (第二时间) / between (第一时间) and (第二时间)

描述稳定的data：
The number of XXX remained steady/stable from (第一时间) to (第二时间) / between (第一时间) and (第二时间)
The number of XXX stayed the same from (第一时间) to (第二时间) / between (第一时间) and (第二时间)
There was little change / hardly any change / no change in the number of XXX from from (第一时间) to (第二时间) / between (第一时间) and (第二时间)

描述不同状态的data
Noun form:
steady drop / sharp rise peak / dramatic fall / sharp drop
Verbal form:
(to) bottom out / (to) reach the bottom / (to) increase gradually / (to) reach a plateau / (to) remain steady

描述the highest point以及the lowest point
高点极值：
The monthly profit / The figures / The situation ...
+peaked in (月份/年) <准确时间点用at XXX> at XXX% / XXX(极点data)
或者reached a peak / a high point at XXX% / XXX(极点data)
低点极值：
XXX bottomed out / reached
+rock / the bottom / a low point
或者hit a trough

此外，在描述过程中还有很多的conjunctional words/sentences，最常用的固定搭配如下：
并列： as well as(句首/中), also, as well(句尾), either, neither, too, moreover, furthermore, in addition, additionally, besides, what's more, apart from ...
举例： for example, for instance, to illustrate, as an illustration, in particular, particularly, especially
事实： as a matter of fact, in fact, actually, as long as, so long as ...
