剑14出来已经有一阵子了，相信不少同学已经刷过一遍了。14与前几本书最大的区别就是：考官范文又回来啦！

在剑10以后，后续的剑桥雅思习题中考官不再提供写作范文，考官范文一直都是我们推测雅思写作评分标准的一个重要风向标，而这个风向标的突然消失，确实让不少学生，和老师，感到了很不适应。

但是，剑14中考官范文又回来了！ 那么我们就来看看，久违的考官范文较老剑桥书究竟有什么变化，又告诉了我们什么呀的信息呢？我们今天就来截取其中的一段来仔细分析一下：

该范文来源于剑14 的test2中的writing task2:

题目为：

Some people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say that there are more important environmental problems.

Discuss both these views and give your own opinion.

以下为考官范文中的第二段：(即主体段一)

survival of the fittest is a nature's way of ruthlessly allowing weaker specimens to die out, although mankind has also contributed to falling animal numbers through hunting and poaching. However, whether saving individual species should be the main focus of environmental protection is debatable. Climate change and excessive use of plastic are just two other major problems that deserve our attention.
