浙江专用2018届高考英语总复习真题研练Week12Monday含解析.docx

Week 12MondayTask 1：阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。(2013浙江，B)Below is a selection from a popular science book.If blood is red，why are veins(静脉) blue?Actually，veins are not blue at all.They are more of a clear，yellowish colour.Although blood looks red when its outside the body，when its sitting in a vein near the surface of the skin，its more of a dark reddish purple colour.At the right depth，these bloodfilled veins reflect less red light than the surrounding skin，making them look blue by comparison.Which works harder，your heart or your brain?That kind of depends on whether youre 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 youre 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 dont they grow back in grownups?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 become damaged，decayed and infected by bacteria.Once this second set of teeth has grown in，youre done.When theyre gone，theyre gone.This is because nature figures youre 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 isnt because theyre shrinking all over.They simply lose height as their spine(脊柱) becomes 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 34 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 dont really shrink！It is not that they are growing backwardstheir legs，arms and backbones getting shorter.When they do get shorter，its because the spine has shortened a little.Or，more often，become more bent and curved.Why does spinning make you dizzy(眩晕的)?Because your brain gets confused between what youre seeing and what youre feeling.The brain senses that youre spinning using special gravityandmotionsensing 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 youre moving while youre not!Where do feelings and emotions come from?Mostly from an ancient part of the brain called the limbic system.All mammals have this brain areafrom 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 complex 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，its “use it，or lose it”！Its not that exercise makes you healthy；its more that a lack of exercise leaves your body weak and easily affected by disease.【语篇解读】人体很复杂，有很多奥秘。对此，你知道多少？本文可以告诉你。1What is the colour of blood in a vein near the surface of the skin?ABlue. BLight yellow.CRed. DDark reddish purple.答案D细节理解题。根据第一个标题下的“.its more of a dark reddish purple colour.”可知答案。2Why do some old people look a little shrunken as they age?ABecause their spine is in active use.BBecause they are more easily affected by gravity.CBecause they keep growing backwards.DBecause their spine becomes more bent.答案D细节理解题。根据第四个标题下的“They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity(重力)”可知，老年人变矮是因为脊柱收缩和弯曲造成的。B项“老年人更容易受重力影响”在文中没有提及；A、C两项也没有类似的描述。3Which of the following statements about our brain is true?AIn the long run，our brain probably works harder than our heart.BWhen our brain senses the spinning，we will feel dizzy.CThe brains of the other mammals are as complex as those of humans.DOur feelings and emotions come from the most developed area in our brain.答案A细节理解题。根据第二个标题下的第三句“But，in the long run，your brain.”可知答案为A项。此题最易误选B项，根据第五个标题下的最后一句可知，眩晕是由于 “你已经不动了，而你的大脑认为你还在动”的错觉引起的。4What is the main purpose of the selection?ATo give advice on how to stay healthy.BTo provide information about our body.CTo challenge new findings in medical research.DTo report the latest discoveries in medical science.答案B写作意图题。考生易误选D项，但是in medical science在医学领域，概括失误。文章主要涉及我们身体的问题，包括身体的、情绪的等等。故选择B项较全面。Task 2：词汇积累1more of 更多的2by comparison相比之下3kind of 有点儿4in the long run从长远来看5fall out 脱落6shrink v收缩7get confused 感到困惑8as far as.is concerned 就而言Task 3：经典句式1That kind of depends on whether youre busy thinking or busy exercising.那有点取决于你是忙于思考还是忙于运动。解读句中whether.or.引导名词性从句。仿写老汽车站是否应该被一个现代化的宾馆代替仍然在讨论之中。It is still under discussion whether the old bus station should be replaced with a modern hotel or not2Your heart works up to three times harder during exercise, and shifts enough bl
