SAT閱讀中有一類假設(shè)題，它和其它題型的區(qū)別在于它不僅需要理解定位點(diǎn)的句子，還需要邏輯關(guān)系的推理。那么，解決這類問題有什么方法呢?

這一類題題干的基本特征就是含有一個(gè)詞assumption。通常題目會(huì)問文章的某幾行是基于什么樣的一個(gè)假設(shè)(based on或rests on)，也就是問原文能夠成立的條件是怎樣的。在SAT的閱讀考試當(dāng)中，通常能在出題點(diǎn)看到的是導(dǎo)致的某個(gè)結(jié)果或達(dá)到的某個(gè)目的。比如問一個(gè)方法基于什么樣的假設(shè)，意思就是說要達(dá)到某個(gè)目的，這樣的方法為什么能夠有效。

具體思路為，若把原文看成B，選項(xiàng)看成A，那么A是B的假設(shè)，意思就是說若A成立B就一定成立(由A一定能推出B)，而若B成立A不一定成立(即B不一定能推出A)。比如說，你想長壽，就要少抽煙少喝酒，這句話基于的假設(shè)就是只要少抽煙少喝酒就一定能長壽。

做題的時(shí)候，理解出題點(diǎn)后要對自己提問為什么出題點(diǎn)的內(nèi)容能夠成立，在五個(gè)選項(xiàng)中找到一個(gè)符合這個(gè)提問的選項(xiàng)。

例如OG中900頁的一道題：

My physiotherapist expressed himself similarly: "Adaptation follows a different path in each person. The nervous system creates its own paths. You are the neurologist--you must see this all the time.

The physiotherapist's remarks reveal the assumption that

A. patients have complete control over the progress of their recovery

B. each neurologist follows a different path to understanding

C. all neurologists are aware of the nervous system's adaptability

D. the author is inadequately informed about the intricacies of the muscular system

E. some neurologists consider both healthy and injured brain processes to be parallel

題目問理療師的話揭示了一個(gè)什么假設(shè)。理療師的意思是：適應(yīng)對于每個(gè)人來說都是基于不同的路徑的。神經(jīng)系統(tǒng)創(chuàng)建了它自己的路徑，你就是那個(gè)神經(jīng)學(xué)家，你必須時(shí)時(shí)刻刻看到這一點(diǎn)。意思也就是說你作為一個(gè)神經(jīng)學(xué)家，必須時(shí)刻了解神經(jīng)系統(tǒng)創(chuàng)建不同適應(yīng)的不同路徑。理解選項(xiàng)后可以發(fā)現(xiàn)，只有C選項(xiàng)“所有的神經(jīng)學(xué)家都對神經(jīng)系統(tǒng)的適應(yīng)性有意識”成立時(shí)，這句話才是能夠成立的，其他的都為不相關(guān)項(xiàng)。

真題：

I had been trained in the tradition of acting called "psychological realism." A basic tenet of psychological realism is that characters live inside of you and that you create a lifelike portrayal of the character through a process of realizing your own similarity to the character. When I later became a teacher of acting,I began to became more and more troubled by the self-oriented method. I began to look for ways to engage my students in putting themselves in other people's shoes. This went against the grain of the psychological realism tradition,which was to get the character to walk into a classroom of people in their real lives.

The author's explanation in the fourth paragraph suggests that the "self-oriented method" rests on the assumption that

A. audience members appreciate complex nuance of character

B. the playwright's biography provides the main evidence for interpreting character

C. actors have already felt the full range of human emotions

D. actors are extremely independent and self-serving people.

E. Actors' lives become fulfilled through their dramatic portrayals.

可以看到題干所問的self-oriented method就是文中說到的psychological realism。而這個(gè)方法的一個(gè)基本理念就是角色就住在你體內(nèi)，你通過一個(gè)實(shí)現(xiàn)自身與角色相似性的過程，來創(chuàng)造一個(gè)活生生的對角色的扮演。為什么這個(gè)方法能夠成立呢，為什么能夠通過實(shí)現(xiàn)自身與角色相似性的過程，來創(chuàng)造活生生的角色扮演呢?顯然，只有選項(xiàng)中的C選項(xiàng)“演員已經(jīng)體會(huì)過了所有人類情感”成立，這一點(diǎn)才能夠成立。

從剛剛這道例題中我們也可以看出，假設(shè)題的和其它題型的重大區(qū)別還在于正確答案中允許極端詞的存在，甚至很多只有含有極端詞的答案才是正確的，考生需要耐心體會(huì)其中的邏輯關(guān)系。
