SWT一直都是PTE考试的重中之重，但因为机经命中率比较高，考生往往忽略了练习的重要性，背一遍机经就去考试了。考试的时候如果纯靠回忆，很容易在高度紧张的时候忘记，而且一旦题目稍有变化将会不知所措，大大影响作文成绩。由于PTE的交叉打分机制，SWT一定程度上也决定着阅读分数的高低。
以下是3月更新的考题Columbus的分析，并附上高分参考答案。
When Christopher Columbus arrived atHispaniola during his first transatlantic voyage in the year A.D. 1492. theisland had already been selected by Native Americans for about 5,000 years. Theoccupants in Columbus’s time were a group of Arawak Indians called Tainos wholived by farming, were organized into five chiefdoms, and numbered around halfa million (the estimates range from 100,000 to 2,000,000). Columbus initiallyfound them peaceful and friendly, until he and his Spaniards began mistreatingthem.
Unfortunately for the Tainos, they had gold, which the Spanish coveted butdidn’t want to go to the work of mining themselves. Hence, the conquerorsdivided up the island and its Indian population among individual Spaniards, whoput the Indians to work as virtual Slaves, accidentally infected them withEurasian diseases, and murdered them. By the year 1519, 27 years afterColumbus’s arrival, that original population of half a million had been reducedto about 11,000, most of whom died that year of smallpox to bring thepopulation down to 3,000 and those survivors gradually died out or becameassimilated within the next few decades. That forced the Spaniards to lookelsewhere for slave labors.
解析：
文章的开头第一句话交代了哥伦布到达的时间，作为一个背景提供给了我们。
第二句话中的Tainos告诉了我们当时居住在岛上的居民的名字以及他们的作息方式。
初期双方相处较为和平，但是随着西班牙人变的贪婪无言，更觊觎于印度人的金子之后，他们之间的关系便开始恶化。
而由于西班牙人的懒惰，他们并不想自己去工作，只好将小岛及岛上的人口按比例分配并奴役了印度人。在这个过程中，不小心传染给了他们Eurasian diseases，并且疾病直接导致了Tainos人口的急剧减少。最后由于无人可以奴役，西班牙人只好放弃了这座岛，重新选择其他的地方继续寻找奴隶。
由此我们可以看出，整篇文章其实讲得更偏重于Tainos这种人口在当时岛上急剧减少的这一事件。而导致这一事件的原因则是前来想要conquer，即为征服他们的西班牙人。最后导致的结果，就是Tainos人口几乎减少为零，使得西班牙人不得不弃岛另寻他处。
按照以上思路，我们不难推测出，这几乎可以是一个故事的标准模板，起因，经过，结果。因此我们的答案也按照以上思路进行即可。
最后附上参考答案：
Tainos, having access to gold, had peacefuland friendly relationship with the Spanish before the Spanish finallymistreated them, forced them to work as virtual slaves and accidentallyinfected them with deadly Eurosian diseases, which led to the consequence thatthe population dwindled significantly, forcing the Spaniards to look elsewherefor slave labors. Initially peaceful and friendly until beganmistreating them。
