However, when there is only a small difference between them, the effect of colour is enoughtipthe balance. The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant.Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar results in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchell’s work shows that the powerful males — the ones who are more successful with females — have a brighter red nose than other males.As well as the studies on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds’ success with female zebra finches, Zebra finches already have bright red beaks (鸟喙), so this study suggests that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from theUniversityofGlasgowsay that the birds’ brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, andhis colleagues think they have found proof that bright red or orange beaks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females.Meanwhile, what about those athletes who win in their events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing?4. According to their research. Hill and Barton conclude that ________.A. the colour of clothing has an effect on most sport eventsB. red should be the choice of colour for clothing in sportsC. red plays a role when competitors are equally capableD. athletes perform better when surrounded by bright red5. The underlined word “tip” in Paragraph 2 is closest in meaning to ________.A. achieveB. advanceC. keepD. change6. The example of the blue footed booby proves that ________.A. male birds use different body parts to draw attentionB. red is not the only colour to attract female birdsC. blue gives female birds the same advantageD. blue can indicate how healthy a bird is7. What can be inferred from the passage?A. The colour red gives male animals the most advantage.B. Male zebra finches prefer to have red plastic rings on their legs.C. Rules on sports clothing are going to be changed.D. Athletes wearing red may have an advantage over their opponents.CWhen I was a kid, my mom set aside some breakfast food for supper every nowand then. I remember one night after a long, hard day at work, my mom placed a plate of eggs, sausage, and a plate of extremely burnt biscuits on the table. I waited to see if my dad would get annoyed.All my dad did was to reach for the biscuits, smile at my mom and ask me how my day at school had been. I don't remember what I told him that night but I do remember watching him add butter and jelly on that ugly burnt biscuit and ate every bite of that thing. He never made a face nor uttered a word about it!When I rose from the table that evening, I remember hearing my mom apologize to my dad for overcooking the biscuits and I will never forget what he said, “Honey, I love burnt biscuits every now and then."Later that night, I went to say good night to my daddy, and I wondered if he really liked his biscuits burnt. He wrapped me up in his arms and said gently, "Your mom put in a hard day at work today and she is really tired. Besides, a little burnt biscuit never hurt anyone!As I have grown older, I've thought about that many times. Life is full of imperfect things and imperfect people. Learning to accept each other's faults and choosing to celebrate each other's differences contribute to ahealthy, growing, and lasting relationship. We could extend this philosophy to any relationship, such as a husband-wife, parent-child, or friendship. Don't put the key to your happiness in someone else's pocket. Keep it in your own. So, please pass me a biscuit, and yes, the burnt one will do just fine.8. How did the author's dad react to the burnt biscuit?A. He set it aside for breakfast.B. He ate butter and jelly instead.C. He uttered his complaints loudly.D. He ate it up as if nothing happened.9. Which of the following words can best describe the author's dad?A. Caring.B. Determined.C. ProudD. Hardworking.10. What does the author suggest people do in the last paragraph?A. Show understanding to imperfect things.B. Ask the children to respect their parents.C. Enjoy the over-cooked biscuits willingly.D. Make important decisions on your own.11. In which section of a magazine may this passage appear?A. History and culture.B. Family and relationship.C. Cuisine and health.D. Entertainment and sports.DChimps use loud calls and gestures to make their feelings known but until now, the exact meaning for individual movements has remained a mystery. Now researchers believe they have translated the key gestures used in the chimp community and identified their intentions for the first time.From 4,351 gestures, experts were able to identify 66 that are used for 19 specific message meanings, including showing a foot to tell a child they can climb on their back. The researchers were able to narrow down these 66 gestures to 36 that are used intentionally to achieve 15 purposes. The translations were made by Dr Catherine Hobaiter and her colleagues at St Andrews University in Scotland.Dr Hobaiter used behavior sampling and filmed all recorded cases of gestural communication. Other gestures include stomping their feet to ask another chimp to stop what they are doing, and slapping objects together to ask another to follow them. Of the 19 meanings,17 encouraged interactions to start, or to develop, such as “move closer,” and “change play”. Some of the gestures were found to have more than one meaning. and only 10 of the66 gestures were used for only a single meaning.Researchers collected a total of 471 video clips from two social groups of chimps at a shelter near Kinshasa, Democratic Republic of Congo. As well as identifying what the gesture means, they also discovered the technique needed to increase the chances of success.“Human children use gestures to communicate before they produce their first words, and their earliest gestures typically appear around 10 months of age,” explained the researchers. “In great apes, there is good evidence that language-trained individuals are capable of acquiring and understanding signals, but this is far less clear in their natural communication. ”12. Chimps slap the objects to____________.A. tell others to stop what they are doingB. ask others chimps to join themC. gather other chimps to move closerD. encourage interactions to start13. What did researchers find after studying 471 video clips?A. Chimps trained in language are good at understanding signals.B. Two social groups of chimps live at a shelter near Kinshasa.C. Language-trained individuals do well in natural communication.D. Chimps’earliest gestures appear around 10 months of age.14. How is the last paragraph developed?A. By analyzing causes.B. By examining differences.C By making comparisons. D. By following time order.15. What can be a suitable title for the text?A A New Research on Chimps B. Human Children and ChimpsC. Getting the Chimps Trained for LanguageD. Translating the Sign Language of Chimps第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2020年广东省佛山市顺德区桂洲中学高三语文第三次联考试题及参考答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下面的文章，完成下面小题挺拔之姿朱以撒晋人普遍有好竹之癖，打开魏晋史册，一群生机勃勃我行我素的人就涌了出来，在山阴道上的竹林深处，放浪形骸，快然自足，得大自在。

这当然是我三十几岁以后才意识到的。

我和魏晋间人相近之处，就是有过比较长的山野生活，与竹相近。

常常会站在山顶，看山峦连绵起伏，竹海无际。

那时我想着自己的出路，如果能像一竿竹子这般凌空而起那就好了。

竹海里纤尘不染，枝叶让天水洗净，摇曳中偶尔闪过阳光的光泽，它们的顶端是最先接触到每一天太阳的光芒的，不禁使我艳羡。

山野稼穑，先是基于温饱的认识——每一竿竹都可以构成生存的支架，把一个个家庭托住，不至于坠入饥寒之中。

而每一枚笋，春日之笋也罢，冬日之笋也罢，对于一位腹内空洞的人而言，简单地烹调之后，无异于美味了。

那些没有成为餐桌美味者，不舍昼夜继续伸长，令人仰望。

那些被山农认为是成熟了的竹子，在叮叮咚咚的刀斧声中倒下，削去枝叶，顺着规划好的坡道滑下，被长长的平板车载着，进入再加工的程序。

和竹子一样，人也是善于生存的植物，贫瘠清苦中也会挣扎着生长。

我注意到一些竹子的确没有长好，是吃力地拱出石块的，此后也就一直不能顺畅，总是被压制着扭曲着，不禁让人生出怜悯。

只是我一直认为它会更具备倔强的美感，它的根后来制成了一个老者形象的工艺品，比其他的更有铁枝虬干的峥嵘了。

待到我在鹤峰原度假，已经到了闲适的年龄了。

风随夕阳西下而愈加强劲，一些植物已在形态上仓皇失措，叶片翻飞如鸟兽惊散。

竹林在随风俯仰中显示了一种从容，在徐徐的摇曳里，山野之风的张狂之力往往被斯文地化解开来。

在魏晋的文字中有不少“徐徐”的记录，“徐徐”看起来只是肢体上的动作，实则是内心的从容优雅。

内心慢了，整个人的举止也就慢了，斯文了，有风度了。

竹被称为四君子之一，它在四君子中是最为清俊的，风来了，风过了，余韵袅袅。

人类的专门基因在黄曲霉素的作用下会发生突变。

A tiger was recently seen on the Siner Russian border（边界），but there is no evidence to suggest this is the same tiger or that it had lost its way from Russia.Wherever it may have come from, cross-border protection of endangered species is a problem. According to Ma Jianzhang, a senior wild animal researcher in China, tigers know no borders, which have been built to stop humans from illegally crossing over. However, these borders also stop the free movement of tigers, thus preventing their breeding（繁殖）and exchange of genes.The Sino-Russian border alsocomes in the way ofprotecting tigers in the region. Data show about 500 to 550 Siberian tigers, or over 90 percent of the species, live in the wild in Russia; 27 live in the wild in China, and 50 inthe border region. Sometimes tigers lose their way across the border and that is hindering（妨碍）efforts to stop illegal hunting and protecting them.Fortunately, both China and Russia have realized this problem and are working toward solving it. As early as 2010, the two countries established a cross-border protection network aimed at strengthening communication on protecting tigers in the northeast. The countries have also held anti-poaching（反偷猎）activities together. In 2019, two national parks from the two countries signed a three-year deal to share research data on tigers, greatly improving the living conditions of Siberian tigers in the wild.However, much more needs to be done to protect the species. It is necessary to combine the tiger protection areas in the two countries. That will require greater efforts from both sides and some difficulties might remain even then. Fortunately, both countries have been taking effective measures to provide the endangered species a better home.4. What's the original purpose of setting up the Sino-Russian borders?A.

All theme parks inBritainhave cafes, restaurants, picnic areas and gift shops, so you'll still have plenty to see and do when you and the kids have been on enough rides. There are usually smaller “funfair“ rides and games as well, so younger children won't get bored. Several theme parks also have other attractions next to them, e. g. water parks often open all year round, unlike the theme parks.Whenever you are inBritain, there's likely to be a theme park within one or two hours,drive, bus ride or train journey. Several theme parks even have accommodation(膳宿)so you can stay for a day or two if you want to make a trip into a short holiday.Prices forUKtheme parks vary considerably; some have an entrance price which allows you to go on all the rides, while in others you have to pay for every ride individually. It can also make a difference whether you go during peak time or not. For example, tickets always cost more during school holidays and weekends than they do during the weekdays.Theme parks always get very busy during the summer months, so if you don't like crowds ifs usually a good idea to go earlier or later in the year!If you're thinking of visiting aUKtheme park, it's worth having a look for special offers on tickets. Products such as chocolate bars and cereals sometimes have " buy one get one free" offers on theme park tickets, so keep a look out in shops and supermarkets.8.

Introduction to Famous Theme ParksDThis past year, I've found myself returning again and again to lines of poetry by Emily Dickinson. Like many people, I've needed the curing effects of reading more than ever. As scientists and psychologists will tell you, books are good for the brain and their benefits are particularly vital now.Books expand our world, providing an escape and offering novelty, surprise and excitement. They broaden our view and help us connect with others. Books can also distract us and help reduce ourmental chatter.When we hit the “flow state" of reading where we're fully lost in a book, our brain's mode network calms down. It's a network of brain that is active and gets absorbed in thinking and worrying endlessly when we are not doing anything else.There is so much noise in the world right now and the very act of reading is kind of meditation. You disconnect from the chaos around you.You reconnect with yourself when you are reading. And there's no more noise.In 2020, the NPD Group recorded the best year of book sales since 2004. Yet even as people are buying morebooks,many are reporting they're having a harder time getting through them. It's difficult for your brain to focus on a book when it's constantly scanning for threats to keep you alive.Our fight-or-flight response has been consistently activated.Sometimes I picture my brain as a cartoon brain with little arms and legs, fighting with a book I am holding and screaming: “Can't you see I'm busy!” Anxiety causes our brain to produce a flood of stress,which consumes our energy and makes it harder to concentrate.Then one day in December sitting on my couch, I remembered how much I like to read"The House of Mirth" every few years around the holidays. The memory inspired me to pick up the familiar book, opened it up and started reading.I just kept going.The comfort and distraction and brain-opening experience gave me peace.So return to something familiar.12. What does the underlined part “mental chatter” in Paragraph 2 mean?A. Getting lost in a book.B. Non-stop inner anxiety.C. Chatting with the author.D. Powerful network of brain.13. What do we know about reading according to the text?A. It can treat our headache.B. It can calm down the noisy people.C. It forces us to concentrate.on thinking.D. It makes us communicate with ourselves.14. Why was it difficult for people to finish reading books in 2020?A. People bought too many books.B. The books were too difficult to understand.C. People just wanted to escape from the threat.D. The life threat disturbed people's focus on books.15. Why is the author's experience mentioned in the last paragraph?A. To rid people of concern for safety.B. To present an effective reading way.C. To wake up memories of an old book.D. To recommend the book he/she reads.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
