Paying more for a ticket to see a film in 3D is the cause of annoyance of many a cinema-goer's life．But there may be a（n） （41）H to doing so，as a study has claimed that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests．
The research was led by neuroscientist（神經(jīng)科學家） Dr Patrick Fagan from Goldsmiths University in London．More than 100 people took part in the experiment，where participants watched Disney film Big Hero 6in either（42）A type or RealD 3D．They also carried out a brain-training-style test before and after seeing a part from the film．The test covered memory，reaction time and cognitive （認知的） function，and the results were later（43）I．
According to the research，participants（44）B a 23 percent increase in cognitive processing，as well as an 11percent increase in reaction time．
Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain （45）G in the future．"These findings are more significant than you might think，"he said．"It is a fact that people are living longer and there is a（n）（46）J decline in cognitive brain function in old age which can damage future quality of life．There has never been a better time to look at ways to improve brain function．The initial results of this study indicate that 3D films may（47）C play a role in slowing this decline．"
A second part of the experiment involved those watching the film being fitted with headsets（耳機） that（48）K brain activity and this too showed heightened activity when watching 3D．According to the results，participants were seven percent more engaged with what they were watching，adding to the argument that 3D movies are more like watching real-life-something．"A seven percent rise in emotional engagement is （49）E remarkable．Watching in 3D gives the viewer such an enriched and quality experience，as these results show，"he said．"In evolutionary（50）F，the results of both parts of the test certainly make sense.3D films are more likely to heighten the senses and cause emotional arousal-this，in turn，makes the brain run at quicker speeds，"Dr Fagan added．
分析 文章介紹了一項研究成果．3D電影對人的大腦有鍛煉的作用．研究通過實驗發(fā)現(xiàn)，通過觀看3D電影，人的大腦在認知和反應方面的功能可以得到提高，并且可以延緩老年人大腦功能的衰退．
解答 1．H 句中as a study has claimed that 3D films exercise the brain表達的是觀看3D電影的好處，可以知道前面說的是這樣做的好處benefit．
2．A 句中either…or…要么…要么…，用來連接兩個表示選擇關(guān)系的對象，后面是Real 3D，前面也應該是某種類型，standard type標志類型的電影．
3．I 句中The test covered memory，reaction time and cognitive （認知的） function表達測試的內(nèi)容，得出的結(jié)果要進行比較compare；句中的results是比較的對象，位于句首，要用被動語態(tài)．
4．B 句意表達的是根據(jù)這項研究的要求，參與測試的人要體驗experience認知過程和反應時間；文章講述的是過去的事實，要用一般過去時態(tài)．
5．G 文章第一段有3D films exercise the brain and improve short-term functioning3D電影可以鍛煉大腦，通過大腦的功能．
6．J 句意表達的是事實表明年紀大了，大腦的認知功能會有明顯的下降．
7．C 句意表達的是研究表明3D電影可能在延緩這種認知下降中起到重要作用．
8．K 句意表達的是通過佩戴耳機，這種耳機可以掃描參與者在觀看電影時大腦的活動．
9．E 句中是用來修飾形容詞remarkable，用副詞extremely表示強調(diào)的語氣．
10．F 短語搭配．in evolutionary terms從進化論的角度而言．
點評 語法填空題是考查學生的語言運用能力．解題時，要在理解文章的基礎上，靈活運用語法知識，如詞性，時態(tài)，名詞單復數(shù)，連接詞，代詞，冠詞等判斷空白處應填寫的內(nèi)容．答完后，還要通讀全文，核對所填單詞形式是否正確，是否符合語境．
