在托福瀏覽測驗中，細節題占領了一半上下的標題，那若何搞定托福瀏覽細節題呢?控制準確的答題技能是異常主要的。下面咱們來看看解答細節題該有的步調吧。
一、找癥結詞
在標題中找癥結詞，是解題的第一步。但是，癥結詞怎樣找?甚麽樣的詞能力作為癥結詞?許多同窗會如許答復：這還不簡略!比擬級和第一流，數字，大寫。沒錯，這些都是咱們常見的定位詞。那末，用如許的辦法，咱們看看怎樣來定位下面這道題。這是TPO28第一篇文章underground water中的第八題：
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.
在這道題內裏，既沒有大寫，也沒有時光，更沒有比擬級。看到這個題，很多門生就傻眼了，這該怎樣去定位?是以，定位詞不單單是指咱們以前所學過的，大寫，比擬級，還應當包含名詞，形容詞，動詞等等。這些詞均可以贊助咱們來定位。是以，在這道題中，咱們可以用relationship，permeability，和porosity來定位。為何用這幾個詞來定位?由於標題問的是relationship。是誰的relationship?是permeability和porosity之間的幹系。
二、找癥結詞地點的句子
依據第一個步調找到了響應的癥結詞，接下來該怎樣做呢?有許多同窗會說，回文章找唄。好，那咱們回到相對於應的文章中，來找一下癥結詞地點的句子。
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。
咱們來看一這下這段筆墨。在整段中，咱們都沒有找到含有relationship的句子。這個時刻，眾人所曉得的，讀癥結詞地點的句子，這條方法就行欠亨了。此時，咱們該怎樣辦呢?須要眾人先找出含有porosity的句子。This pore space is known as porosity and is expressed as a percentage of the total rock volume。從這個句子，咱們可以曉得，porosity指的是巖石蘊藏水的才能。然後，咱們再來找到含有permeability 的句子：The ability of water, or other fluids, to flow through the interconnected pore spaces in rocks is termed permeability。也便是說巖石的小孔銜接起來，讓水留過，這便是滲入滲出性，也便是permeability。那末此時，咱們來理清晰兩者的幹系：巖石的儲水才能，便是多孔性;巖石的小孔相接洽，水可以或許流過，這便是滲入滲出性。
三、應用消除法
讀懂了癥結的句子以後，咱們再來看ABCD四個選項，用消除法來選出準確的謎底。
A選項說，巖石的孔越多，多孔性就越高，滲入滲出性越低。原文並無說，多孔性越高，滲入滲出性就越低。B選項說巖石的孔沒有相連，那末就有高的多孔性和低的滲入滲出性。這句話恰好表現了原文的內容：多孔性是水的貯存才能，小孔相連，水能留過，是滲入滲出性。孔不相接洽，那末水留太小孔的才能就天然很低。C是說假如水很輕易的留過巖石的孔，便是有滲入滲出性，然則多孔性很低。這個文章也沒有說。D選項說巖石有高的滲入滲出性就有高的多孔性，反之亦然。這個原文也沒有說。
是以，眾人在查對選項的時刻，必定要記著，通常文章中提到的才可以或許選，文章中沒有提到的就不可以或許選。必定要相符文章。
依據上文中給咱們的具體解題步調，咱們在做細節題時應當留意：
(1)找癥結詞。癥結詞包含名詞，動詞，形容詞，比擬級等等，不克不及僅僅範圍於曩昔所學的大寫，數字等等。
(2)找癥結詞地點句子。假如文章中沒寫出明白含有這個癥結詞的句子，那末咱們須要讀清晰文章的相幹句，找到他們之間內涵的邏輯接洽。
(3)應用消除法。用消除法的時刻必定要留意，要相符文章，文章中沒有提到的必定是不克不及選的。
細節題固然看起來輕易，但仍舊須要考生有賣力剖析的耐煩和對付這種題型解題步調的闇練度，準確應用答題技能而且多加演習，信任每一名正在備考瀏覽的同窗們都能在細節題部門拿到只管即便多的分數!
