　托福阅览搞定细节题一、找关键字

　　在题目中找关键字，是解题的榜首步。但是，关键字怎样找?什么样的词才干作为关键字?许多同学会这么回答：这还不简单!比较级和最高级，数字，大写。没错，这些都是咱们多见的定位词。那么，用这么的方法，咱们看看怎样来定位下面这道题。这是TPO28榜首篇文章underground water中的第八题：

　　Q8 According to paragraph 2, what is the relationship between permeability and porosity?

　　A. The more pores a rock has, the higher its porosity but the lower its permeability

　　B. Rocks with many internal spaces that are not connected with each other will have high porosity but low permeability.

　　C. If water flows through a rock easily, it has permeability but low porosity.

　　D. Rocks that have high permeability have high porosity and vice versa.

　　在这道题里边，既没有大写，也没有时间，更没有比较级。看到这个题，许多学生就傻眼了，这该怎样去定位?因此，定位词不仅仅是指咱们之前所学过的，大写，比较级，还应该包含名词，形容词，动词等等。这些词都能够协助咱们来定位。因此，在这道题中，咱们能够用relationship，permeability，和porosity来定位。为什么用这几个词来定位?因为题目问的是relationship。是谁的relationship?是permeability和porosity之间的联系。

　　托福阅览搞定细节题二、找关键字地点的语句

　　依据榜首个过程找到了相应的关键字，接下来该怎样做呢?有许多同学会说，回文章找呗。好，那咱们回到相对应的文章中，来找一下关键字地点的语句。

　　Groundwater is stored in a variety of rock types. A groundwater reservoir from which water can be extracted is called an aquifer. We can effectively think of an aquifer as a deposit of water. Extraction of water depends on two properties of the aquifer: porosity, and permeability. Between sediment grains are spaces that can be filled with water. This pore space is known as porosity and is expressed as a percentage of the total rock volume. Porosity is important for water-storage capacity, but for water to flow through rocks, the pore spaces must be connected. The ability of water, or other fluids, to flow through the interconnected pore spaces in rocks is termed permeability. Fractures and joints have very high permeability. In the intergranular spaces of rocks, however, fluid must flow around and between grains in a tortuous path; this winding path causes a resistance to flow. The rate at which the flowing water overcomes this resistance is related to the permeability of rock.

　　咱们来看一这下这段文字。在整段中，咱们都没有找到含有relationship的语句。这个时分，咱们所知道的，读关键字地点的语句，这条方法就行不通了。此刻，咱们该怎样办呢?需要咱们先找出含有porosity的语句。This pore space is known as porosity and is expressed as a percentage of the total rock volume.从这个语句，咱们能够知道，porosity指的是岩石贮藏水的才能。然后，咱们再来找到含有permeability 的语句：The ability of water, or other fluids, to flow through the interconnected pore spaces in rocks is termed permeability.也即是说岩石的小孔连接起来，让水留过，这即是渗透性，也即是permeability。那么此刻，咱们来理明白二者的联系：岩石的储水才能，即是多孔性;岩石的小孔相联系，水能够流过，这即是渗透性。
