Unit 18 Beauty 一、閱讀理解。 Can exercise during childhood protect you against memory loss many decades later? Exercise early in life seems to have lifelong benefits for the brain，in rats at least. “This is an animal study，but it shows that physical activity at a young age is very important—not just for physical development，but for the whole lifelong track of cognitive(認知的)development during ageing，”says Martin Wojtowicz of the University of Toronto，Canada. “In humans，it may delay the appearance of Alzheimers disease(阿爾茨海默病)，possibly to the point of preventing it.” Wojtowiczs team divided 80 young male rats into two equal groups，and placed running wheels in the cages of one group for a period of six weeks.Around four months later—when the rats had reached middle age—the team taught all the rats to connect an electric shock with being in a specific box.When placed in the box，they froze with fear. Two weeks later，the team tested the rats in three situations：exactly the same box in the same room，the same box with the room arranged differently，and a pletely different box in a different room. The rats without access to a running wheel when they were young now froze the same percentage of times in each of these situations，suggesting they couldnt remember which one was dangerous.But those that had been able to run in their youth froze 40 to 50 percent less in both changed box settings. “The results suggest the amount of physical activity when were young，at least for rats，has influence on the brain and cognitive health—in the form of better memories—when were older，” says Arthur Kramer of Northeastern University in Boston，who has found that，in humans，exercise promotes the growth of new brain cells. 1．The study shows that ________. A．physical activity is important for physical health B．using the running wheels is of benefit to the rats growth C．physical activity can prevent humans Alzheimers disease D．the more exercise a rat has when young，the better memory it will possess when older 2．How are Paragraph 3 and 4 mainly developed?

C．Benefit. D．Study. 4．What is the authors attitude towards the animal study? A．Negative. B．Objective. C．Critical. D．Doubtful. 【解題導語】本文為說明文，介紹了一項科學研究，從而得出早期鍛煉對大腦終身有好處的結(jié)論。 1．D　考查細節(jié)理解。根據(jù)第一段內(nèi)容尤其是第二句“Exercise early in life seems to have lifelong benefits for the brain, in rats at least”可知，早期鍛煉似乎對大腦終身有好處，至少對老鼠來說是這樣的。故選D項。 2．C　考查寫作手法。根據(jù)第三段的“Wojtowiczs team divided 80 young male rats into two equal groups...Around four months later...they froze with fear”和第四段的“Two weeks later，the team tested the rats in three situations”可知，本文第三、四段描述了Wojtowicz的研究小組對老鼠進行實驗的過程。C項意為“通過描述過程”，故選C項。A項意為“通過分析原因”；B項意為“通過舉例子”；D項意為“通過展示不同點”。這三項均不符合第三、四段的發(fā)展脈絡。 3．A　考查代詞指代。根據(jù)第二段的“but it shows that physical activity at a young age is very important”及“In humans，it may delay the appearance of Alzheimers disease(阿爾茨海默病)”可知，身體活動很重要，對人類來說，它可能會推遲阿爾茨海默病的出現(xiàn)。因此“it”在文中指的是“physical activity”， A項與其同義，故選A項。 4．B　考查觀點態(tài)度。通讀全文可知，作者介紹了對老鼠進行實驗的過程及其結(jié)果，并引用數(shù)據(jù)進行說明，由此可知作者對動物研究的態(tài)度是很客觀的。B項意為“客觀的”，故選B項。 二、閱讀下面材料，在空白處填入適當?shù)膬?nèi)容(1個單詞)或括號內(nèi)單詞的正確形式。 Every city has a particular smell, which enriches the 61.____________ (imagine) of many a tourist.Vienna is no different.There 62.____________ (be) plenty of smells on little streets, roads and squares, during the night and during the day.

It allows us to learn from the past, both the mistakes made and the successes achieved. One of the benefits of history is reading how other people both famous and totally unknown have overe tremendous challenges in their life. These challenges, although particular to a person, or to a certain time in the past, or occurring in a different country or culture, all convey the same thing. 　2　 　3　 He encountered many failures while on the road to finally inventing the modern day light bulb. He could be held out as an example of a person who never gave up. 　4　 However, he did not let those failures stop him. He had a dream and he just kept trying different things until he did reach success. Or, consider the story of Abraham Lincoln who managed to bee President of the United States even though he suffered many setbacks and personal losses. Most of us only realize the success of Mr Lincoln being President. 　5　 His life was not an easy one. His story is one that motivates us to keep moving forward no matter what obstacles we have in life. A. History has a lot of influence on us. B. Take for example the story of Thomas Edison. C. History has some very unique qualities about it. D. I am sure he was discouraged by his many failures. E. They convey wisdom in their short stories of perseverance. F. Few of us knew about the many challenges he had to overe. G. Only those with courage to face challenges can hope to live their dreams. 【文章大意】本文講述歷史對我們的生活是如何進行指導的。 1. 【解析】選C。根據(jù)上文提到“History is a record of what has happened in the past. 歷史就是對過去發(fā)生事情的記錄, ”以及下一句內(nèi)容可知應選C?！皻v史有一些獨一無二的特質(zhì)”。 2. 【解析】選E。根據(jù)上文提到“These challenges, although particular to a person, or to a certain time in the past, or occurring in a different country or culture, all convey the same thing. 雖然對于某個人來說, 或者對于過去的某個特定時間來說, 或者對于發(fā)生在一個不同的國家或文化中的事情來說, 這種挑戰(zhàn)是很獨特的, 但都表達相同的內(nèi)容”, 故選E“它們同樣傳達了智慧?！笔菍ι弦痪涞脑敿氄f明。 3. 【解析】選B。根據(jù)下文提到“He encountered many failures while on the road to finally inventing the modern day light bulb. 他經(jīng)歷很多的失敗才最終發(fā)明了現(xiàn)代的電燈”, 故選B“以愛迪生的故事為例”。 4. 【解析】選D。根據(jù)下文“However, he did not let those failures stop him. ”但是他沒有讓那些失敗阻止過他”, 是對上文的轉(zhuǎn)折。故選D“我肯定他也對多次的失敗氣餒過”。 5. 【解析】選F。根據(jù)上文提到“Most of us only realize the success of Mr Lincoln being President. 許多人只看到林肯成為總統(tǒng)”, 故選F“我們卻很少有人知道他必須克服的眾多困難”。 五、書面表達。 (2017山西省3月質(zhì)量檢測)假如你是李華，你的英國朋友Edward正在學習漢語，希望你推薦一個適合他學習漢語的網(wǎng)站。請你根據(jù)以下內(nèi)容，給他回復郵件。 推薦網(wǎng)站：.edchinese. 網(wǎng)站內(nèi)容：1.中文情景對話、中國風俗、中文電影、中文歌曲、成語和唐詩等； 2．有在線教師答疑解惑。 注意：1.詞數(shù)100左右； 2．可以適當增加細節(jié)，以使行文連貫； 3．開頭和結(jié)尾已為你寫好，不計入總詞數(shù)。 Dear Edward， I’m more than pleased to know that you are learning Chinese.I’d like to remend .edchinese. to you.________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ Yours， Li Hua One possible version： Dear_Edward， I’m_more_than_pleased_to_know_that_you_are_learning_Chinese.I’d_like_to_remend_.edchinese._to_you.
