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 .

Most importantly, it 18 modifies and enhances the games you play to 19 on the strengths you are developing--much like a(n) 20 exercise routine requires you to increase resistance and vary your muscle use.

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，不接狀語時其意義不完整。四個選項中，A項where指代地點，放在空白處與文意相符，所以是正確選項。B項when指代時間，與從句中的a moment ago沖突，可以排除。C項that雖然可以引導賓語從句，但無實意，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why引導原因，雖然也可用于引導賓語從句，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improves表示“改善，增進，提高”;B項fades表示“褪色，衰老”;C項recovers表示“恢復，重新獲得”;D項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的結(jié)果，所以A項和C項可以排除。而D項collapses表示大腦功能徹底崩潰，描述過于嚴重，與文意不符，所以可以排除。只有B項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致的記憶力和思維能力減弱。因此，正確答案是B項。

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，表明這句話與前面的分句是并列關(guān)系，應該是對上文的進一步說明，主題應該還是圍繞“鍛煉(exercises)”。A項responses表示“反應，響應”;B項roundabouts表示“迂回路線”;C項workouts表示“鍛煉，練習，實驗”;D項associations表示“關(guān)聯(lián)，社團”。四個選項中最符合文章意思的是C項，意思是“恰當?shù)木�神訓練可以在很大程度上提高我們基本的認識功能”。

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，本自然段強調(diào)的是大腦訓練對提高基本認知功能的重要性，即雖然我們在大腦中建立聯(lián)系的能力天生有差異，但實際上通過大腦訓練我們可以改變智力的狀態(tài)，這是因為“這些聯(lián)系是通過努力和練習建立的(because these connections are made through effort and practice)”。由此不難看出，科學家們相信智力可以提高或者變化實際上是基于努力的程度(mental effort)，所以正確答案應該選B項according to“根據(jù)”。A項instead of表示“而不是”;C項apart from表示“除了……之外”;D項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，大腦訓練程序提供關(guān)于參與者的表現(xiàn)和進步的詳細反饋。四個選項中常與feedback搭配的是D項on，因此正確答案是D項。
