考過(guò)雅思的同學(xué)都知道，雅思閱讀中的填空題涉及的考點(diǎn)有很多。因果邏輯考點(diǎn)就是其中高頻的考點(diǎn)之一。因果關(guān)系考點(diǎn)本質(zhì)上難度不大，但是關(guān)鍵要學(xué)會(huì)識(shí)別其標(biāo)識(shí)詞，這樣才能一下?lián)糁锌键c(diǎn)所在，快速解題。下面我們就來(lái)看看因果邏輯是如何滲透到填空題當(dāng)中進(jìn)行考察的：

　　有明顯的因果邏輯詞

　　e.g.劍633 Q39

　　題：cells less damaged by disease because fewer_____ are emitted

　　文：One possibility relates to the ATP-making machinery’s emission of free radicals,which are thought to contribute to aging and to such age-related diseases as cancer by damaging cells.

　　解析：看到題目有明顯的表示原因的詞because之后，通過(guò)定位找到原文對(duì)應(yīng)信息句。原文出現(xiàn)contribute to也是明顯的因果邏輯，所以答案free radicals會(huì)很快找到。（類似這樣表示因果邏輯的詞還有很多，比如lead to/result in等，大家一定要在做題過(guò)程中多總結(jié)）

　　有隱性的因果邏輯詞

　　e.g.劍1422 Q26

　　題：These were blamed for the spread of disease for hundreds of years,including epidemics of ______ in London and Paris in the middle of the 19th century.

　　文：Miasmas were feared as the principal agents of disease and epidemics for centuries,and were used to explain the spread of infection from the Middle Ages right through to the cholera outbreaks in London and Paris during the 1850s.

　　解析：題目中be blamed for直譯過(guò)來(lái)是“受到….責(zé)備”，暗含了因果關(guān)系，即正是由于某事件的出現(xiàn)，才使得疾病傳播了好幾百年。而原文be used to explain也是在間接表達(dá)因果，所以在解題時(shí)找到對(duì)應(yīng)的邏輯信號(hào)詞，答案cholera就迎刃而解。

　　用破折號(hào)表示因果關(guān)系

　　e.g.劍521 Q3

　　題：There were several reasons for the research into plastics in the nineteenth century,among them the great advances that had been made in the field of______ and the search for alternatives to natural resources like ivory.

　　文：The impetus behind the development of these early plastics was generated by a number of factors—immense technological progress in the domain of chemistry,coupled with…..

　　解析：答案chemistry。用詞匯表達(dá)因果邏輯大家想必很熟悉了，但是用符號(hào)比如破折號(hào)來(lái)表示卻是大家容易忽視的一點(diǎn)。題目當(dāng)中there were several reasons for是比較明顯的因果邏輯信號(hào)表達(dá)，而在原文中，除了factors表示“因素”之外，破折號(hào)對(duì)解題起到了很關(guān)鍵的作用，因?yàn)槠普厶?hào)起到解釋的作用，暗含了因果邏輯。

　　用分詞表示原因狀語(yǔ)

　　e.g.劍1341 Q11

　　題：Ferreira went to Falmouth to repair damage that a _____ had caused.

　　文：Badly damaged in a gale in 1922,she was put into Falmouth harbour in southwest England,for repairs.

　　解析：題目中出現(xiàn)了明顯的因果關(guān)系邏輯詞cause，定位到信息句之后發(fā)現(xiàn)文中過(guò)去分詞短語(yǔ)所作的后置定語(yǔ)其實(shí)充當(dāng)了原因狀語(yǔ)，相當(dāng)于一個(gè)簡(jiǎn)化了的原因狀語(yǔ)從句。這也是因果關(guān)系的一種體現(xiàn)。對(duì)于這個(gè)語(yǔ)法現(xiàn)象還不太熟悉的同學(xué)一定要徹底將其搞懂，否則再遇到類似分詞表達(dá)原因的現(xiàn)象還是很難識(shí)別，做題還是會(huì)很困難。

　　總之，因果邏輯的表示在題目中的考法很多樣化，以上列舉的四點(diǎn)是較為高頻也是需要同學(xué)們掌握的。不知道你們學(xué)會(huì)了嗎？
