2019-2020年高考英語總復習真題研練Week12Monday含解析 Task 1：閱讀下列短文，從每題所給的四個選項(A、B、C和D)中，選出最佳選項。 (xx·浙江，B)Below is a selection from a popular science book. If blood is red，why are veins(靜脈) blue? Actually，veins are not blue at all.They are more of a clear，yellowish colour.Although blood looks red when it’s outside the body，when it’s sitting in a vein near the surface of the skin，it’s more of a dark reddish purple colour.At the right depth，these blood－filled veins reflect less red light than the surrounding skin，making them look blue by parison. Which works harder，your heart or your brain? That kind of depends on whether you’re busy thinking or busy exercising.Your heart works up to three times harder during exercise，and shifts enough blood over a lifetime to fill a supertanker.But，in the long run，your brain probably tips it，because even when you’re sitting still your brain is using twice as much energy as your heart，and it takes four to five times as much blood to feed it. Why do teeth fall out，and why don’t they grow back in grown－ups? Baby (or “milk”) teeth do not last long；they fall out to make room for bigger，stronger adult teeth later on.Adult teeth fall out when they bee damaged，decayed and infected by bacteria.Once this second set of teeth has grown in，you’re done.When they’re gone，they’re gone.This is because nature figures you’re set for life，and what controls regrowth of your teeth switches off. Do old people shrink as they age? Yes and no.Many people do get shorter as they age.But，when they do，it isn’t because they’re shrinking all over.They simply lose height as their spine(脊柱) bees shorter and more curved due to disuse and the effects of gravity(重力)．Many (but not all) men and women do lose height as they get older.Men lose an average of 3－4 cm in height as they age，while women may lose 5 cm or more.If you live to be 200 years old，would you keep shrinking till you were，like 60 cm tall，like a little boy again？No，because old people don’t really shrink！It is not that they are growing backwards—their legs，arms and backbones getting shorter.When they do get shorter，it’s because the spine has shortened a little.Or，more often，bee more bent and curved. Why does spinning make you dizzy(眩暈的)? Because your brain gets confused between what you’re seeing and what you’re feeling.The brain senses that you’re spinning using special gravity－and－motion－sensing organs in your inner ear，which work together with your eyes to keep your vision and balance stable.But，when you suddenly stop spinning the system goes out of control，and your brain thinks you’re moving while you’re not! Where do feelings and emotions e from? Mostly from an ancient part of the brain called the limbic system.All mammals have this brain area—from mice to dogs，cats，and humans.So all mammals feel basic emotions like fear，pain and pleasure.But since human feelings also involve other，newer bits of the brain，we feel more plex emotions than any other animal on the planet. If exercise wears you out，how can it be good for you? Because our bodies adapt to everything we do to them.And as far as your body is concerned，it’s “use it，or lose it”！It’s not that exercise makes you healthy；it’s more that a lack of exercise leaves your body weak and easily affected by disease. 【語篇解讀】　人體很復雜，有很多奧秘。對此，你知道多少？本文可以告訴你。 1．What is the colour of blood in a vein near the surface of the skin? A．Blue. B．Light yellow. C．Red. D．Dark reddish purple. 答案　D　[細節(jié)理解題。根據(jù)第一個標題下的“...it’s more of a dark reddish purple colour.”可知答案。] 2．Why do some old people look a little shrunken as they age? A．Because their spine is in active use. B．Because they are more easily affected by gravity. C．Because they keep growing backwards. D．Because their spine bees more bent. 答案　D　[細節(jié)理解題。根據(jù)第四個標題下的“They simply lose height as their spine(脊柱) bees shorter and more curved due to disuse and the effects of gravity(重力)．”可知，老年人變矮是因為脊柱收縮和彎曲造成的。B項“老年人更容易受重力影響”在文中沒有提及；A、C兩項也沒有類似的描述。] 3．Which of the following statements about our brain is true? A．In the long run，our brain probably works harder than our heart. B．When our brain senses the spinning，we will feel dizzy. C．The brains of the other mammals are as plex as those of humans. D．Our feelings and emotions e from the most developed area in our brain. 答案　A　[細節(jié)理解題。根據(jù)第二個標題下的第三句“But，in the long run，your brain...”可知答案為A項。此題最易誤選B項，根據(jù)第五個標題下的最后一句可知，眩暈是由于 “你已經(jīng)不動了，而你的大腦認為你還在動”的錯覺引起的。] 4．What is the main purpose of the selection? A．To give advice on how to stay healthy. B．To provide information about our body. C．To challenge new findings in medical research. D．To report the latest discoveries in medical science. 答案　B　[寫作意圖題?？忌渍`選D項，但是in medical science在醫(yī)學領域，概括失誤。文章主要涉及我們身體的問題，包括身體的、情緒的等等。故選擇B項較全面。] Task 2：詞匯積累 1．more of 更多的 2．by parison相比之下 3．kind of 有點兒 4．in the long run從長遠來看 5．fall out 脫落 6．shrink v．收縮 7．get confused 感到困惑 8．a(chǎn)s far as...is concerned 就……而言 Task 3：經(jīng)典句式 1．That kind of depends on whether you’re busy thinking or busy exercising. 那有點取決于你是忙于思考還是忙于運動。 [解讀]句中whether...or...引導名詞性從句。 [仿寫]老汽車站是否應該被一個現(xiàn)代化的賓館代替仍然在討論之中。 It is still under discussion whether the old bus station should be replaced with a modern hotel or not． 2．Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. 你的心臟在你運動的時候工作強度是平時的三倍，而且在漫長的一生中它所提供的血液足以填滿一艘超級巨輪。 [解讀]倍數(shù)＋形容詞/副詞的比較級＋(n.)＋than ...是一種倍數(shù)表達法。 [仿寫]不要懼怕鯊魚，因為你被閃電擊中的幾率可能是被鯊魚襲擊的30倍。 Don’t be frightened by sharks: you are 30 times more likely to be hit by lightning than be attacked by a shark.
