首先：in the first place, to begin with, first of all

然后：in the following stage, afterwards, from then on, after that

同时：at the same time, meanwhile, simultaneously

最后：in the final stage, at last, finally, eventually

此外，在描写过程步骤时，一些恰当的动词是非常重要的，如在对“the glass bottle recycling”这个过程的描写中，一些动词：recycle, transport, grind, flow等都是非常准确的。

3. 如果要避免流程图的描写变成流水帐，那么在语言上的一些改写和变化是非常重要的。下面，将为大家介绍两类常见的句子间衔接的方法：

before, after which, following which, followed by

The glass bottles are sent to a collecting point by customers, after which, they are transported to a cleaning plant.

to do, doing, done, 定语从句

The glass bottles are sent to a collecting point by customers ready to be transported to a cleaning plant.

The glass bottles which are sent to a collecting point by customers are then transported to a cleaning plant.

地理变迁图Map

相对流程图而言，地理变迁图的难度会低于流程图。

难点：

1. 物体太多，不知如何有序描写

2. “建造”这个动词的多样表达

笔者也相应的来一一解答存在于考生中的关于地理变迁图的疑问。

1. 地图题的描写思路，可以按照方位顺序来描写其在所给时间段中的变化，如变多，变少，消失，新建等。考生还需掌握一些方位词的表达方法：

in the north, to the north, above the river, on the edge of the garden, at the southwestern corner, along the river bank

2. 在地图题中，无疑会出现很多新出现的建筑，所以考生必须要用很多表示“建造”意思的动词来对其描写。

建造：build, construct, establish, set up, can be found

出现：emerge, arise, appear

只要考生在备考时充分掌握了以上介绍的两类图形的应对技巧，以及两类图形必备的词汇和句型，相信考生对付这两类题型会胸有成竹。
