　　2010年6月12日新托福综合写作的阅读片段：

　　We now know that there was a period of global cooling that lasted from the 16th to 19th centuries. Scientists call it the Little Ice Age because the drop in temperature was not as serious as in a real ice age. There are many hypotheses about what caused the Little Ice Age but it was most likely caused by a combination of events.

　　The Gulf Stream, the ocean current that makes the eastern coast of America and the western coast of Europe warmer than usual, was 10% slower during the Little Ice Age... ...

　　During the Little Ice Age, there was also an increased amount of volcanic activity...

　　Another possible cause of the Little Ice Age was human depopulation...
 

　　我们首先用1秒可以看到的是这篇新托福综合写作的阅读共分4段，是考生们都非常喜欢的1+3结构。接下来，我们不用花大量的时间去从文章第一句话往下看。朗阁老师在此提醒考生们，为了节省时间，我们一定要先看的是第一段的最后一句话，因为根据经验来看，第一段最后一句话最重要的，前面的内容很多时候都是导入的“废话”，我们不必为“废话”去浪费时间。

　　我们很清楚的就能看到首段最后一句There are many hypotheses about what caused the Little Ice Age but it was most likely caused by a combination of events. 已经非常明确地提出了本文重点是在提Little Ice Age的原因在于a combination of events。接下来考生只需要在每一段去找具体的events即可。
 

　　最后，我们来看一下2010年2月21日新托福综合写作的阅读文章片段：

　　Iron fertilization is based on the idea that when small particles of iron are spread across the upper layers of the ocean, it will stimulate algae and phytoplankton growth. Phytoplankton absorbs carbon dioxide from the air as it grows and, when it dies, traps the carbon dioxide in the deep ocean where it is effectively removed from the atmosphere. Thus, many scientists believe that iron fertilization could be a way for humans to combat global warming. In fact, the fertilization is believed to have some negative impacts on the environment.

　　This plan sounds great in theory, but in practice, iron fertilization can only absorb a small amount of carbon dioxide...

　　Iron fertilization has also been shown to increase growth of algae that produce toxic chemical materials such as domoic acid, which can be fatal to small marine life like fish...

　　Ultimately, iron fertilization relies on disrupting the natural balance of the marine ecosystem...
 

　　同样，这篇文章我们首先看首段最后一句话the fertilization is believed to have some negative impacts on the environment, 发现本文大概是要讲fertilization对环境有负面的影响。

　　当然考生会有疑问，什么是fertilization, 若考生还不放心，建议往前推一句，注意不是回到第一句，而是往前推一句，再次确认下什么是fertilization。Many scientists believe that iron fertilization could be a way for humans to combat global warming, 这句话再次确认了首段最后一句的fertilization指的就是iron fertilization, 那么这个词就是这篇综合写作的话题词。

　　考生们可能还会问，到底什么是Iron Fertilization呢?这根本不重要，不信的话，我们回到第一句往下看，会发现即使看懂了这些定义性的分析，也对文章的理解和最后文章的成型没有起到任何作用，更何况对大部分考生来说，这些导入性的概念只会让他们对这篇文章望而却步，让他们紧张而影响后面阅读的理解和整个考试的发挥。

　　所以，很多考生首先抱怨的看不懂阅读是因为怕时间来不及，所以大概扫了一下，造成即使3分钟看完了，也没看懂到底文章说了什么。那么，我们对症下药。既然怕看不完，我们首先解决看不完的问题，势必要做到不该看的(首段开始的导入部分)别看，该看的(文章内的3点细节)一定要细看。
