雖然不是每一個單詞都可以通過構詞法解決掉,但是了解一些最常用的前綴,詞根和后綴,并在背單詞的過程中多思考,多練習,無疑在閱讀過程中對生詞就不抵觸,可以使自己如虎添翼。先來測試一下自己的單詞量吧。這里有10個單詞,都是雅思閱讀中的核心詞匯,看看你認識幾個:輕松說對6個的為達標,能說對8個的就視為優(yōu)秀,當然10個全答對的同學自然很了不起。但是如果不達標的同學,也不用著急,在看完了我為你們準備的構詞法核心表格之后,就可以輕松認知這下面的單詞啦。

必備知識1:前綴變詞意,后綴變詞性
在背記單詞的時候,我們要了解到,一個單詞的前綴決定這個單詞詞意,比如like(喜歡)和dislike(不喜歡),后綴決定這個單詞的詞性,比如understand(v。理解)和understandable(adj。可以理解的)在雅思閱讀中,很多時候考點詞我們并不認識,但是可以通過前綴來辨別單詞是否一致,或者抵觸。(我們經常稱為單詞的方向為正向,或是負向);后綴我們可以判別單詞的詞性,利用最基本的知識:副詞修飾動詞和形容詞,形容詞修飾名詞,我們在做填空題的時候不難利用橫線前面單詞的詞性來推測出橫線里面要填的單詞的詞性,從而在原文中縮小范圍。比如:as a result of geographical_______ 我們知道后綴為-al的形容詞后綴,因此橫線中要填的一定為名詞,那么名詞的后綴又有-tion,-ity,-ness。答案從形式上先確定了,找起來就特別容易。說了這么多,讓我們來看看下面這個單詞:inescapable,是由前綴表相反的"in-以及形容詞后綴"-able構成,中間余下的部分"escap"很容易看出是escape逃離的變體,所以這個單詞是形容詞,釋義為不可逃避的,不可逃離的。
