Use a website full of brain games or download the right apps, and within 20 minutes youll be doing your part to sharpen your memory and slow the decline of your mental functions. At least thats what the panies behind this booming industry would have you believe. But is it true? Concrete proof about the benefits of brain games is hard to e by, experts say, when it es to measurably improving aspects of mental fitness, like having a good memory. “People would really love to believe they could do something like this and make their brain better, but theres just no solid evidence，” says Randall W. Engle, a primary investigator at the Attention & Working Memory Lab at the Georgia Institute of Technology. Thats not to say brain games are without benefits. Experts say these kinds of mental exercises can change your brain. The brain changes with just about everything you do, including mental training exercises. But numerous studies have shown that brain games lack what researchers call “transfer”. In other words, repeating a game over and over again teaches you how to play the game and get better at it but your brain aging wont necessarily e to a stop. “Its like, you walk through fresh snow, and you leave a trace. If you walk the same route again, the trace gets deeper and deeper，” says Ursula Staudinger, director of the Butler Columbia Aging Center at Columbia University. The fact that structural changes occur does not imply that in general this brain has bee more capable. It has bee more capable of doing exactly the tasks it was practicing. 語(yǔ)篇解讀：本文是一篇科普說(shuō)明文。據(jù)說(shuō)腦力游戲可以提高記憶力和延緩大腦功能的衰退，但是研究表明，腦力游戲僅能提高玩家對(duì)游戲技巧的掌握，并不能真正阻止大腦的老化；其作用還有待證明。 1．We can infer from the first paragraph that ________. A．brain games improve the memory B．brain aging actually can be quitted C．people dont believe brain games D．the author doubts the effect of brain games 解析：選D　推理判斷題。根據(jù)第一段最后兩句“At least thats what the panies behind this booming industry would have you believe. But is it true？”可知，這個(gè)蓬勃發(fā)展的行業(yè)背后的公司會(huì)讓人相信腦力游戲可以提高記憶力和延緩大腦功能的衰退，但作者對(duì)其真實(shí)性表示懷疑，故D項(xiàng)正確。 2．What does Engle think of the functions of brain games? A．They really make some difference. B．Their effects still need proving. C．People like to be led by the nose. D．People dont believe the effects. 解析：選B　細(xì)節(jié)理解題。根據(jù)第二段第二句“People would really love to believe they could do something like this and make their brain better, but theres just no solid evidence”可知，Randall W. Engle 認(rèn)為這種游戲的功能還有待證明，故B項(xiàng)正確。 3．The underlined word in Paragraph 3 most probably means “________”． A．stopping the brain aging B．having the brain working C．making the brain more passive D．speeding up the brain aging 解析：選A　詞義猜測(cè)題。根據(jù)第三段最后一句“In other words, repeating a game over and over again teaches you how to play the game and get better at it but your brain aging wont necessarily e to a stop.”可知，多次重復(fù)玩一個(gè)游戲，會(huì)讓你更加熟練地操作游戲，但大腦老化并不能停止；再結(jié)合畫(huà)線詞所在句可知，很多研究都表明腦力游戲不能使大腦停止老化，故A項(xiàng)正確。 4．Which can be the best title of the passage? A．Games Stop Brain Aging B．Unavoidable Brain Aging C．Games Roles Need Proving D．Games Improve Your Brain 解析：選C　標(biāo)題歸納題。通讀全文可知，本文介紹了能提高記憶力和延緩大腦功能衰退的腦力游戲，但是研究表明，這些游戲僅能提高玩家對(duì)游戲技巧掌握的能力，并不能真正阻止大腦的老化；游戲的作用還有待證明。據(jù)此可知，C項(xiàng)最適合作為本文的標(biāo)題。 B (2019武漢市武昌區(qū)調(diào)研)Every now and then, a product es along that proves itself a plete gamechanger, as is the case with a new British brand and invention, Eyejusters — the reading glasses that you can focus yourself — for less than ￡ 70! With 6 in 10 people wearing glasses in the UK, those with perfect vision are increasingly in the minority. And of those who do require glasses, many find themselves requiring two or three pairs of glasses in order to plete different tasks throughout the day. As well as being an added expense on_top_of everything else, this also means carrying around (and trying not to lose) those extra pairs! Eyejusters allow you to instantly change the lens (鏡片) strength of your glasses with hidden dials, tucked just inside the frames themselves. Eyejusters work by the wearer simply turning the concealed eyeDials to change the focus to fit your needs. The lenses adjust from ＋0.00 to ＋3.00 D. They also have antiscratch technology and are lightweight in design so you arent paying the price of fort for convenience. The creator of Eyejusters, Owen Reading — who came up with the idea for Eyejusters with friend David Crosby, who studied physics at Oxford with him, explained: “Lots of people need reading glasses but they need glasses with lots of different strength. They might have a pair with ＋1 prescription－strength lenses for the puter, ＋2s for reading and ＋3s for really closeup stuff. Eyejusters replace the need for multiple pairs of reading glasses, by covering the whole range from zero to ＋3, which is the strongest you will find in overthecounter products.” He added: “If you wear reading glasses, these are a much more flexible alternative. You can put them on and just turn the dial until what you want to see es into focus. They are much like using binoculars (雙筒望遠(yuǎn)鏡)．” 語(yǔ)篇解讀：本文是一篇說(shuō)明文，介紹了一種視力調(diào)節(jié)器，人們可以調(diào)整鏡片焦距以達(dá)到不同的目的。 5．Which has the closest meaning to the underlined part “on top of” in Para.2? A．Joan stays on_top_of the news by reading newspapers. B．A submarine can run under water as well as on_top_of water. C．When I turned the corner, I was right on_top_of the post office. D．He promised to help us and on_top_of that he lent us many books. 解析：選D　詞義猜測(cè)題。畫(huà)線部分上文講的是，很多人需要兩三副眼鏡來(lái)完成不同的任務(wù)，而畫(huà)線部分所在句是說(shuō)這不但是一筆額外的費(fèi)用，還意味著到哪里都要帶著額外的眼鏡。由此可以推斷，on top of 的意思是“除……之外”，所以D項(xiàng)表達(dá)的含義與畫(huà)線部分最接近。 6．Eyejusters are popular for the following reasons EXCEPT their ________. A．new brand B．a(chǎn)ntiscratch technology C．light weight D．low price 解析：選A　細(xì)節(jié)理解題。根據(jù)第一段最后的“for less than ￡ 70”可知，它的價(jià)格低，排除D項(xiàng)；根據(jù)第三段最后一句中的“They also have antiscratch technology and are lightweight in design”可知，它有抗抓痕技術(shù)，還很輕便，排除B項(xiàng)和C項(xiàng)。故選A項(xiàng)。 7．How can you make Eyejusters serve different purposes? A．By folding glasses. B．By adjusting lenses. C．By bining glasses. D．By changing lenses. 解析：選B　細(xì)節(jié)理解題。根據(jù)第三段首句“Eyejusters allow you to instantly change the lens (鏡片) strength of your glasses with hidden dials, tucked just inside the frames themselves.”可知，人們通過(guò)調(diào)整鏡片的焦距來(lái)服務(wù)于不同的目的，所以選B。 8．Who need Eyejusters most according to Owen Reading? A．People having perfect vision. B．People wearing reading glasses. C．People changing glasses constantly. D．People preferring fortable glasses. 解析：選C　推理判斷題。根據(jù)第二段第二句可知，為了完成一天之內(nèi)不同的任務(wù)，很多人需要兩三副眼鏡。Eyejusters這種新型的眼鏡正好可以彌補(bǔ)這個(gè)缺陷，可以通過(guò)調(diào)整鏡片焦距來(lái)達(dá)到不同的目的，所以選C。 Ⅱ.完形填空 It was still raining.
