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 Mammal Diversity 的分析，并附上高分参考答案。

先上原文：
Mammals can be one of the hardest-hit groups by habitat loss, and a lot of research has been carried out to find the best ways to conserve mammal diversity.

Much of this research has focussed on very large-scale changes in land use and the impacts this will have on overall mammal diversity. However, many important decisions about land use are made at much more local scales, for example at the level of individual landowners.

Now, in a detailed study led by Imperial College London that looked at mammal diversity across different small-scale landscapes in Borneo, researchers have identified previously logged forests as an overlooked source of refuge for mammals.

These ‘selectively logged’ forests, where only certain tree species are removed, are often considered to be degraded and are frequently cleared to make way for plantations. The new results, published in the journal Ecological Applications, suggest they should be better protected.

The team recorded mammals using trap-and-release techniques and motion-sensing cameras over three years, creating an unprecedented 20,000 records of species in three land-use types: old-growth forest, logged forest and oil palm plantation. This is one of the most intensive studies of rainforest mammal diversity ever undertaken.

To their surprise, they found that mammal diversity for large mammals, like the clouded leopard and civets, was similar for both old-growth forests and logged forests. For small mammals, such as squirrels and rodents, the diversity was actually higher in logged forests.

Mammals can be one of the hardest-hit groups by habitat loss, and a lot of research has been carried out to find the best ways to conserve mammal diversity.

哺乳动物可能是栖息地丧失最严重的群体之一，并且已有大量研究在进行，以寻找保护哺乳动物多样性的最佳方法。

该篇文章的中心思想是哺乳动物多样性的研究，所以重点取后半句

Much of this research has focused on very large-scale changes in land use and the impacts this will have on overall mammal diversity. However, many important decisions about land use are made at much more local scales, for example at the level of individual landowners.

这些研究的大部分内容都集中在土地利用的大规模变化及其对整体哺乳动物多样性的影响上。然而，许多关于土地使用的重要决策都是在更多的地方范围内进行的，例如在个别土地所有者的层面上。

该段主要说的是很多研究的专注领域，并且给出一个转折表明另一个领域更重要

Now, in a detailed study led by Imperial College London that looked at mammal diversity across different small-scale landscapes in Borneo, researchers have identified previously logged forests as an overlooked source of refuge for mammals.

现在，在伦敦帝国理工学院领导的一项详细研究中，研究了婆罗洲不同小规模地界上的哺乳动物多样性，研究人员发现以前记录的森林是一个被忽视的哺乳动物的避难所。

该段主要说了一个比较特殊的研究，专门开展在小规模地界上

These ‘selectively logged’ forests, where only certain tree species are removed, are often considered to be degraded and are frequently cleared to make way for plantations. The new results, published in the journal Ecological Applications, suggest they should be better protected.

在这些“选择性砍伐”的森林中，只有某些树种被移除，这种森林通常被认为是退化了的，并且经常被夷平以便为种植土地服务。发表在“生态应用”杂志上的新结果表明它们应该得到更好的保护。

该段主要说了这种选择性开采的森林应该受到保护

The team recorded mammals using trap-and-release techniques and motion-sensing cameras over three years,creating an unprecedented 20,000 records of species in three land-use types: old-growth forest, logged forest and oil palm plantation. This is one of the most intensive studies of rainforest mammal diversity ever undertaken.

该团队使用捕获和释放技术和动作感应摄像机记录了三年多的哺乳动物的生活，在三种土地利用类型中创造了前所未有的20,000种物种记录：古老的森林，被砍伐的森林和油棕种植园。这是有史以来对雨林哺乳动物多样性进行的最深入研究之一。

该段主要说这项研究非常地深入

To their surprise, they found that mammal diversity for large mammals, like the clouded leopard and civets, was similar for both old-growth forests and logged forests. For small mammals, such as squirrels and rodents, the diversity was actually higher in logged forests.

令他们惊讶的是，他们发现大型哺乳动物如云豹和果子狸的哺乳动物多样性，，在古老的森林和被砍伐的森林来说都是相似的。对于小型哺乳动物，如松鼠和啮齿动物，它们的多样性在被砍伐的森林中实际上更高。

该段主要说研究的结果

根据摘选的重要信息点，可以组成以下短句：

1. A lot of research, focusing on large-scale changes in land use, has been carried out to conserve mammal diversity.

2. Many important decisions about land use are made at much more local scales.

3. Forests where only certain tree species are removed should be better protected.

4. An intensive study of rainforest mammal diversity, researchers find similar results for large mammals, and the diversity for small mammals was higher in logged forests.

可以将这些句子合理运用连词连成长句
