完型填空在考研英語復(fù)習(xí)中的位置其實(shí)是一個(gè)比較尷尬的角色，因?yàn)榇蟛糠挚忌鷷�把主要精力放在閱讀和作文的攻克上，相比這兩大部分而言，完型填空的分值確實(shí)相對較少，但并不等于可以就此放過。在2016考研的戰(zhàn)場上，一分可能就是成功與失敗的距離。今天我們就通過真題來看看，完型填空的那個(gè)"空"到底想考查什么。

　　【相關(guān)真題】

　　As many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be. We suddenly can't remember 1 we put the keys just a moment ago, or an old acquaintance's name, or the name of an old band we used to love. As the brain 2 , we refer to these occurrences as "senior moments." 3 seemingly innocent, this loss of mental focus can potentially have a(an) 4 impact on our professional, social, and personal 5 .

　　Neuroscientists, experts who study the nervous system, are increasingly showing that there's actually a lot that can be done. It 6 out that the brain needs exercise in much the same way our muscles do, and the right mental 7 can significantly improve our basic cognitive 8 . Thinking is essentially a 9 of making connections in the brain. To a certain extent, our ability to 10 in making the connections that drive intelligence is inherited. 11 , because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate 12 mental effort.

　　Now, a new Web-based company has taken it a step 13 and developed the first "brain training program" designed to actually help people improve and regain their mental 14 .

　　考查邏輯關(guān)系

　　第1題，答案A

　　【解析】空白處的詞語作"We suddenly can't remember"的賓語，同時(shí)在賓語從句"we put the keys just a moment ago"中作狀語。需要注意的是：put sth.后常跟介詞短語、形容詞或副詞作狀語，不接狀語時(shí)其意義不完整。四個(gè)選項(xiàng)中，A項(xiàng)where指代地點(diǎn)，放在空白處與文意相符，所以是正確選項(xiàng)。B項(xiàng)when指代時(shí)間，與從句中的a moment ago沖突，可以排除。C項(xiàng)that雖然可以引導(dǎo)賓語從句，但無實(shí)意，在從句中不起作用，放在空白處從句的意義不完整，可以排除。D項(xiàng)why引導(dǎo)原因，雖然也可用于引導(dǎo)賓語從句，但與that一樣，用在空白處從句的意義不完整，所以可以排除。

　　考查詞義辨析

　　第2題，答案B

　　【解析】A項(xiàng)improves表示"改善，增進(jìn)，提高";B項(xiàng)fades表示"褪色，衰老";C項(xiàng)recovers表示"恢復(fù)，重新獲得";D項(xiàng)collapses表示"崩塌，暈倒，癱倒"。由上文可知，記憶力和思維能力退化不可能是大腦功能改善或者恢復(fù)的結(jié)果，所以A項(xiàng)和C項(xiàng)可以排除。而D項(xiàng)collapses表示大腦功能徹底崩潰，描述過于嚴(yán)重，與文意不符，所以可以排除。只有B項(xiàng)fades表示衰老，與文章中提到的"步入中年"這一情況相吻合，指的是大腦功能的退化導(dǎo)致的記憶力和思維能力減弱。因此，正確答案是B項(xiàng)。

　　考查上下文語義連貫

　　第7題，答案C

　　【解析】根據(jù)上文，我們已知，大腦需要像肌肉一樣得到足夠的鍛煉，空白出現(xiàn)的分句由and引導(dǎo)，表明這句話與前面的分句是并列關(guān)系，應(yīng)該是對上文的進(jìn)一步說明，主題應(yīng)該還是圍繞"鍛煉(exercises)"。A項(xiàng)responses表示"反應(yīng)，響應(yīng)";B項(xiàng)roundabouts表示"迂回路線";C項(xiàng)workouts表示"鍛煉，練習(xí)，實(shí)驗(yàn)";D項(xiàng)associations表示"關(guān)聯(lián)，社團(tuán)"。四個(gè)選項(xiàng)中最符合文章意思的是C項(xiàng)，意思是"恰當(dāng)?shù)木�神�?xùn)練可以在很大程度上提高我們基本的認(rèn)識功能"。

　　考查短語

　　第12題，答案B

　　【解析】由第二自然段的第一句話可知，本自然段強(qiáng)調(diào)的是大腦訓(xùn)練對提高基本認(rèn)知功能的重要性，即雖然我們在大腦中建立聯(lián)系的能力天生有差異，但實(shí)際上通過大腦訓(xùn)練我們可以改變智力的狀態(tài)，這是因?yàn)?quot;這些聯(lián)系是通過努力和練習(xí)建立的(because these connections are made through effort and practice)"。由此不難看出，科學(xué)家們相信智力可以提高或者變化實(shí)際上是基于努力的程度(mental effort)，所以正確答案應(yīng)該選B項(xiàng)according to"根據(jù)"。A項(xiàng)instead of表示"而不是";C項(xiàng)apart from表示"除了……之外";D項(xiàng)regardless of表示"不顧"。

　　考查詞語搭配

　　第17題，答案D

　　【解析】本題考查名詞與介詞的搭配。根據(jù)文意，大腦訓(xùn)練程序提供關(guān)于參與者的表現(xiàn)和進(jìn)步的詳細(xì)反饋。四個(gè)選項(xiàng)中常與feedback搭配的是D項(xiàng)on，因此正確答案是D項(xiàng)。

　　其實(shí)完型填空雖然一篇文章有20道題之多，但其實(shí)考查的內(nèi)容也無非就是那幾個(gè)，考生只要掌握了規(guī)律，解答起來就會很容易。建議大家結(jié)合真題進(jìn)行復(fù)習(xí)，把歷年考查同一知識點(diǎn)的題都匯總一下，在理解的基礎(chǔ)上增加閱讀和解題能力。
