比如，我们来看这题：
There is mounting evidence that the frequency and magnitude of landsliding is changing in many parts of the world in response to climate change. This is not surprising, given that precipitation is one of the two external triggering mechanisms--the other being seismic activity--involved in the formation of landslides. Evidence from the past clearly indicates that cycles of elevated landslide activity have been followed by cycles of low activity, and that these are correlated with climate fluctuations over a variety of timescales.
What sets current changes in landslide activity apart is the likely influence of anthropogenic [i.e., human-caused] factors, either acting alone or in concert with climate, which can further modify the process of landsliding and the nature of ecosystem responses. Among these factors, deforestation and land-use change have the potential to influence the frequency and magnitude of landsliding because of their direct effects on vegetation attributes that influence slope stability. The extent and conditions under which mountain ecosystems are resilient to these changes--that is, the amount of disturbance they can absorb before changing into states with different structure and function--are not known. Addressing this issue is crucial for the long-term conservation of mountainscapes.
The author of the passage cites “evidence from the past” in order to
A. support a partial explanation
B. concede a potential objection
C. dismiss an apparent counterexample
D. highlight a scientific consensus
E. account for a historical anomaly
我们来看这个句子作用，首先很快定位到第一段第三句“ Evidence from the past clearly indicates [...] that these are correlated with climate fluctuations over a variety of timescales“
这句紧接第一二句，而且有“clearly indicates”这样的表达，明显是对前面的观点给出一个支持的，根本不存在反对和反例。所以很快可以排除掉B和C。
再来，我们读进去句子，“过往的证据明确显示滑坡活动的周期和气候波动有相关性”，所以没有讲到“historical anomaly”历史上的反常，E也被排除。
最后只有A和D了，我们在这两个中间再看看。很多同学很想选D。确实句子给出了一个已经比较established的解释和证据，而且相对后面”are not known“的论调，这一句很像一个科学界的共识。
但是!这里问的是句子的作用，不是句子的性质。这里“highlight a consensus”对整片文章的论述有什么用?“are not known"的是滑坡的原因吗，大家仔细看看!并不是啊!
我们在文中往前看第二句：“ This is not surprising, given that precipitation is one of the two external triggering mechanisms--the other being seismic activity--involved in the formation of landslides” 文章说有两个原因导致滑坡的形成，一个是降水另一个是地震。
那我们目标句关于气候波动的evidence是不是就是解释了这两个原因中的一个——降水因素!!所以答案是A：support a partial explanation!
在做句子作用类型题目的时候，记得一定要往前看一两个句子。虽不是所有的题的线索都在前面，但是往往作者写文章的时候肯定需要和前面保持一定的逻辑关系，所以这个时候前句就很重要!!!
