涼月解析:雅思考試時(shí)間的選擇
在涼月為考生解答的諸多問題中,有一類問題是考生最關(guān)注的:我該報(bào)哪場(chǎng)考試?
由于雅思考試每次的試題是不同的,因此考生就會(huì)認(rèn)為某些場(chǎng)次的考試相對(duì)簡(jiǎn)單,而某些場(chǎng)次的考試則會(huì)難一些。大家都希望能夠選擇一場(chǎng)相對(duì)簡(jiǎn)單的考試來參加,這樣就可能獲得更好的成績(jī)。但是,這樣的機(jī)會(huì)真的存在嗎?
在幾年前的雅思考試中,這樣的機(jī)會(huì)是存在的。由于2005年以前,雅思考試題庫(kù)中的題目非常少,所以樣本的差異較大,每次考試多多少少都會(huì)存在難度上的差異。而由于當(dāng)時(shí)題庫(kù)小且規(guī)律性極強(qiáng),涼月能夠輕松預(yù)測(cè)到考試的版本。有興趣的同學(xué)可以到3G雅思網(wǎng)翻翻2005年涼月的預(yù)測(cè),基本上全部聽力預(yù)測(cè)只有20多個(gè)版本,只要考舊題命中率就是100%。從2003年起,雅思考試中心開始有計(jì)劃地使用新題,并將新題補(bǔ)充到題庫(kù)之中。2005-2006年引入的新題的數(shù)量達(dá)到了高峰,有時(shí)候聽力、閱讀都會(huì)出現(xiàn)所有的sections全部都是新題的情況,使機(jī)經(jīng)完全失效,目前聽力機(jī)經(jīng)中的大量的V30***和V50***版本都是在那幾年產(chǎn)生的。不過,那幾年出現(xiàn)新題規(guī)律性非常強(qiáng),涼月可以根據(jù)規(guī)律預(yù)計(jì)到哪場(chǎng)出新題,哪場(chǎng)出舊題,因此可以給大家提供報(bào)考場(chǎng)次上的建議。但是,隨著雅思考試題庫(kù)的不斷豐富,目前的考試規(guī)律性已經(jīng)沒有那么強(qiáng)了,而且基本不會(huì)出現(xiàn)全部是新題的考試,多數(shù)場(chǎng)次是由大量舊題和少量新題組合而成的。因此,從出現(xiàn)新題的角度講,每場(chǎng)雅思考試之間的差異已經(jīng)不大了。
那么,在考試難度上是否還有差異呢?由于雅思考試的題庫(kù)已經(jīng)趨于穩(wěn)定,近幾年每年雅思考試中心都會(huì)對(duì)過去一年中所有的考試版本作可靠性評(píng)估,即評(píng)估這些考試版本是否能夠客觀穩(wěn)定的反應(yīng)考生的英語(yǔ)水平,從另一個(gè)角度講,其實(shí)也就是在檢驗(yàn)每場(chǎng)考試的難度差異是否越來越小。
涼月從IELTS ORG提取了2010年度的雅思考試可靠性評(píng)估數(shù)據(jù),給大家分析如下:
