这道oxbow lake的题最近出现的频率非常高，很多同学第一次看到这道题的时候都会纠结于oxbow 这个单词不认识这一点，而事实上oxbow的意思在这道题里并不重要，即使不明白意思，也可以完整的把这个图描述出来。

这道题事实上是一道非常典型的流程图，所以我们第一句话可以说 The graph describes the formation of an oxbow lake.如果在考试的时候时间很短来不及思考，那么我们也可以直接把题目读出来：This graph describes meandering and oxbow lake。之后我们可以按照课上讲过的模板来进行描述，按照顺序对每一个阶段每一个stage分别进行叙述。这道题比较简单的地方是图中已经有了很多文字，即使不太明白图中的内容，可以把这些文字读出来。

This graph describes the formation of an oxbow lake. According to the graph, it is clear that the first stage start from a river running across a plain. The lake has a meander and two necks. After that, it is clear that the narrow of the meander is gradually being eroded by sand and silt. Following that, deposition takes place, sealing off the old meander. Water now takes the quickest route and the meander neck has been cut through completely. By way of conclusion, it is clear that at the last stage, an oxbow lake is left behind when the meander is completely cut-off. This is the formation of an oxbow lake.

这幅图讲述的是马斯洛的需求层次理论，这个理论认为人的需求是分层次的，从基本的生理需求开始逐级上升，向上依次为安全需求，归属感和爱的需求，自尊需求，最高层为自我实现的需求。马斯洛认为只有人的低层次理论得到了满足，才会产生更高层次的需求。这个图虽然是金字塔形状，但是我们可以按照table题的模板来进行描述。由于图上的内容很多，所以我们要进行归类、总结。

This graph describes Maslow’s Hierarchy of Needs in 1970. According to the graph, it is clear that at the bottom there are physiological needs, which is food, water, warmth and rest. The second layer is security needs, including security and safety. After that it is belongingness and love needs, including intimate relationships and friends. The forth layer is esteem needs including prestige and feeling of accomplishment. By way of conclusion, at the top it is self-actualization, which is achieving one’s potential, including creative activities.

有能力的、语速快的同学也可以尽量把右边的分类说出来。

Safety needs and physiological needs are classified as basic needs, also known as D needs. Belongingness and love needs and esteem needs are psychological need. Self-actualization needs are also known as self-fulfillment needs. These three together are B needs.
