雅思閱讀詞匯備考必備的2個(gè)知識(shí)點(diǎn)

單詞是閱讀的基礎(chǔ),沒(méi)有一定量的單詞作為基礎(chǔ),就無(wú)法保證有一定的閱讀速度.那么學(xué)習(xí)一些最基本的構(gòu)詞法知識(shí),就非常重要了.

雖然不是每一個(gè)單詞都可以通過(guò)構(gòu)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(guò)程中多思考,多練習(xí),無(wú)疑在閱讀過(guò)程中對(duì)生詞就不抵觸,可以使自己如虎添翼.先來(lái)測(cè)試一下自己的單詞量吧.這里有10個(gè)單詞,都是雅思閱讀中的核心詞匯,看看你認(rèn)識(shí)幾個(gè):輕松說(shuō)對(duì)6個(gè)的為達(dá)標(biāo),能說(shuō)對(duì)8個(gè)的就視為優(yōu)秀,當(dāng)然10個(gè)全答對(duì)的同學(xué)自然很了不起.但是如果不達(dá)標(biāo)的同學(xué),也不用著急,在看完了我為你們準(zhǔn)備的構(gòu)詞法核心表格之后,就可以輕松認(rèn)知這下面的單詞啦.

必備知識(shí)1:前綴變?cè)~意，后綴變?cè)~性

在背記單詞的時(shí)候,我們要了解到,一個(gè)單詞的前綴決定這個(gè)單詞詞意,比如like(喜歡)和dislike(不喜歡),后綴決定這個(gè)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(shí)候考點(diǎn)詞我們并不認(rèn)識(shí),但是可以通過(guò)前綴來(lái)辨別單詞是否一致,或者抵觸.(我們經(jīng)常稱為單詞的方向?yàn)檎?或是負(fù)向);后綴我們可以判別單詞的詞性,利用最基本的知識(shí):副詞修飾動(dòng)詞和形容詞,形容詞修飾名詞,我們?cè)谧鎏羁疹}的時(shí)候不難利用橫線前面單詞的詞性來(lái)推測(cè)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(lái)就特別容易.說(shuō)了這么多,讓我們來(lái)看看下面這個(gè)單詞:inescapable,是由前綴表相反的"in-以及形容詞后綴"-able構(gòu)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(gè)單詞是形容詞,釋義為不可逃避的,不可逃離的.
