SWT一直都是PTE考试的重中之重，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。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。所以在备考阶段，对每篇SWT真题进行透彻的学习和分析，才是正确的复习方法。
以下是高频考题 印尼火山 的分析，并附上高分参考答案。

On 1815, on the island of Sumbawa in Indonesia, a handsome and long quiescent mountain named Tambora exploded spectacularly, killing a hundred thousand people with its blast and associated tsunamis. No one living now has ever seen such fury. Tambora was far biggerthan anything any living human has experienced. It was the biggest volcanic explosion in ten thousand years, 150 times the size of Mount St. Helens,equivalent to sixty thousand Hiroshima-sized atom bombs.
News didn't travel terribly fast in thosedays. In London, The Times ran a small story actually a letter from a merchant- seven months after the event.But by this time Tambora's effects were alreadybeing felt. Two hundred and forty cubic kilometers of smoky ash, dust and grithad diffused through the atmosphere, obscuring the Sun's rays and causing theEarth to cool. Sun's rays and causing the Earth to cool. Sunsets were usuallybut blearily colorful, an effect memorably captured by the artist J.M.W.Turner,who could not have been happier, but mostly the world existed under anoppressive, dusky pall. It was this deathly dimness that inspired Bryon towrite the lines quoted above.
Spring never came and summer never without summer: 1816 became known as the year without summer. Crops everywhere failed to grow. In Ireland a famine and associated typhoid epidemic killed sixty-fivethousand people. In New England, the year became popularly known as Eighteen Hundred and Froze to Death. Morning frosts continued until June and almost noplanted seed would grow. Short of fodder, livestock died or had to be prematurely slaughtered. In every way it was a dreadful year - almost certainly the worst for tanners in modern times. Yet globally the temperature fell byless than 1 degree Celsius. The Earth's natural thermostat, as scientists wouldlearn, is an exceedingly delicate instrument.
解析：
文章首段讲述1815年印尼某火山爆发，造成10万人死亡并引发了连锁海啸。这次爆发是近1万年以来的最大规模的火山爆发，并给出了其他论点支撑此次火山爆发的猛烈。
第二部分：
News didn't travel terribly fast in thosedays. In London, The Times ran a small story actually a letter from a merchant- seven months after the event.But by this time Tambora's effects were alreadybeing felt. Two hundred and forty cubic kilometers of smoky ash, dust and grithad diffused through the atmosphere, obscuring the Sun's rays and causing theEarth to cool. Sun's rays and causing the Earth to cool. Sunsets were usuallybut blearily colorful, an effect memorably captured by the artist J.M.W.Turner,who could not have been happier, but mostly the world existed under anoppressive, dusky pall. It was this deathly dimness that inspired Bryon towrite the lines quoted above
解析：
第二段开始描写，由于当时消息传播的速度相对较慢，伦敦的The Times在七个月之后才写了一篇从某个商人手中传来的报道。但到那时为止，大家都也已经感受到了火山爆发带来的后果：由于浓烟太多，阻碍了空气的循环，和太阳的照射，最终导致地球温度开始降低。由于浓烟的阻碍，虽然太阳照常落下，但是却只是散发出模糊的光芒和色彩。这幅让人印象深刻的景象则被一位艺术家描绘了出来。然而对于大多数人来说，浓烟只是浓烟而已，让人感受到的只有阴暗和压迫。而这窒息的黯淡却给拜伦带来了启发，才写出了上面引用过的句子。（由于文章只是节选，所以拜伦的诗句应该并没有出现在截取部分中）
第三部分：
解析：
上文提到，由于地球温度开始降低，春天一直没有来临。而1816年也成为了没有夏季的一年。庄稼也没有收成。更悲惨的事件一系列地发生：爱尔兰的伤寒，新英格兰的寒潮，牲口的死亡等等。然而全球的温度却仅仅下降了一摄氏度，这一切都归功于地球的自动调温功能。
总结:
读完文章后我们可以总结出，这是一篇由原因导致phenomenon最后带来负面的后果的文章。
最后附上参考答案：
Caused by one of the biggest explosions of Tambora,a decrease in world’s temperature under heavy smoky ash lead to a series oftragedies in Europe such as the deaths of crops, epidemics of typhoid, coldspells in New England and pre-mature slaughtering of livestock; however, only 1 degree Celsius was witnessed because of the Earth’s natural thermostat.
