But it's the brightest in the blue and green parts of the spectrum(光谱).In other words,the sun might be expected to appear blue or green.But it clearly doesn't. Why is that? The answer has something to do with how our eyes work.Our eyes have three types of special cells called conest(视锥细胞)，and they help us see colors:red, green and blue.When sunlight hits these cells,they send messages to our brain.The brain uses these messages to decide what color we see.If all three cells send the strong messages,we see white light.That's what happens with sunlight.Even though it shines more blue and green light,the sun looks white because our eyes mix all the colors together.That's why the sun looks white to astronauts in space! But on Earth,something different happens.As sunlight passes through the air around Earth,tiny particles()spread out shorter blue waves in every direction.This is why the sky looks blue!At the same time,longer red,yellow,and orange waves pass straight through.So during the day,the sun appears yellow or orange.At sunrise or sunset,it might look redder because the light travels through more air,spreading out even more blue light So,what color is the sun?It depends on where you are.In space,it's white.On Earth,it's often golden or orange.But no matter what,it's still our bright,shiny star! 1.What color does the sun actually shine with?( A.Both blue and green. B.Only the color yellow. C.All colors of the rainbow. 2.毫图片理解题，Which picture can match the information in the text? () The Visible The Yellow (可见的 Sun Sunlight Spectrum 并倒 A. B.

C.Because astronauts see stronger red light from the sun 4.What can we infer from the text? () A.We can see the red,yellow and orange color more easily. B.The sky looks blue because blue waves are spread out by air particles. C.Red,yellow and orange waves can't pass through air around Earth. 63 Passage 10 文体：说明文 文章词数：约270词 难度：★★★★☆ 建议用时：7分钟 You might think math is hard and boring.Could it be that you've been looking at math in the wrong way? With the International Day of Mathematics coming on March 14,we interviewed Professor Li.We asked if math could be beautiful and fun.Here's what Li said. Numbers are beautiful There is math hidden in beautiful human bodies. Measure the length from your head to your belly button (肚脐)and from your belly button to your feet.The ratio (of these two numbers is always around 0.618.This is the golden ratio,which can be seen everywhere,like in nature,music and paintings. In Chinese poems,we can also see the beauty of numbers.As Li Bai wrote,"My boat has left ten thousand mountains far away","A thousand miles in one day"-all these numbers show how fast Li Bai traveled and how happy he felt. Curves(曲线)are beautiful "Sine curves"are beautiful.They go towards the two opposite directions on and on without ever ending. When you look at them,you may feel like standing by the sea and watching the waves slowly moving.When listening to music,the sound waves from guitars or pianos are made up of sine curves."Tangent curve"is like a waterfall,just as Li Bai wrote,"falling down three thousand feet from on high". Formulas(公式)are beautiful There are some amazing formulas.In a right-angled triangle(直角三角形)，the square of the longest side is equal to the sum of the squares of the other two sides. How amazing!Just as Chinese-American mathematician Chen Xingshen said,“Math is fun!” 1.What might happen if the ratio of a thing is around 0.618? () A.It is an unusual object. B.It only happens in human bodies. C.It might bring people a sense of beauty. 64 2.膏写作手法题，Why does the writer mention Li Bai and his poems in the text? () A.To introduce the topic. B.To support his opinion. C.To share the beauty of Li Bai's poems. 3.拿跨学科试题，What does a sine curve look like? 4.主旨大意题，What is the text mainly about? A.Why math is beautiful and fun. B.Why math is difficult and boring. C.How we can learn math in a right way. 话题6科学技术与发明(2023贵州) Passage11(2025贵阳一模) 文体：说明文 文章词数：约270词 难度：★★★☆☆ 建议用时：7分钟 With the rapid development of artificial intelligence (AI),China is using AI and robots in the elderly care service field,offering new solutions to the challenges of an aging population.The latest data shows that China's population aged 60 and above reached 310 million by the end of 2024.It's about 22 percent of its total. Although elderly care robots are still at an early stage compared to industrial robots,some users have already begun to experience the convenience they offer. To improve service quality,China is helping create the first international standard for elderly care robots,setting rules for their design and safety. In Shenzhen,elderly care robots are widely used in nursing homes.They play chess,give treatment,and help old people with movement."These robots improve our lives and show us new ideas,"said Li Xipo,a nursing home director.During the Spring Festival, special robots even helped elderly people climb mountains,showing their potential()in making our lives better. Other cities are also using elderly care robots.In Shenyang,a patient has learned to walk again with theIII.1.Rice Plants 2.on a map 3.popular 6.found 7.completely 8.is dropped 9.eating 10.harmful 4.tradition with creativity 九年级（全）Units13~14 5.Yes,it can.Because rice paddy art is interesting and can I.1.E2.A3.F4.B5.D bring more tourists to the countryside,which helps farmers earn Ⅱ.1.F2.A3.B4.E5.D more money./No,it might not.Because some farmers may not III.1.I million/one million/a million 2.The social problems have enough money or help to start it,so it might not spread to 3.kill sea animals 4.our own bottles more places./..(开放性试题，答案不唯一，言之有理 5.Yes,I will.Because they help to protect the environment and 即可。) save money./No,I might not.Sometimes I forget to take my 九年级（全)Units11~12 own bottle when going out in a hurry./..【解析】开放性试题， I.1.A2.C3.B4.C5.B6.A7.C8.C9.A 答案不唯一，言之有理即可。) 10.B11.C IV.1.hundreds 2.slowly 3.area's 4.noticed 5.them Ⅱ.1.C2.B3.A4.A 6.dangerous 7.to bring 8.is seen 9.are 10.holds III.1.says 2.scientist 3.legs 4.them 5.to eat 第三部分 基础语篇巩固练 题型一完形第二节 Passage 2 Cloze 1 1.C2.B3.B4.B 1.A2.B3.C4.A5.C6.B7.A8.C9.B10.A Passage 3 Cloze 2 1.B2.A3.C4.C 1.B2.C3.C4.B5.C6.A7.A8.A9.C10.B Passage 4 Cloze 3 1.C2.C3.A4.B 1.C2.B3.C4.C5.A6.B7.A8.A9.B10.B Passage 5 Cloze 4 1.C2.A3.A4.B 1.A2.C3.B4.B5.A6.A7.C8.A9.C10.B Passage 6 Cloze 5 1.C2.A3.A4.B 1.C2.C3.B4.A5.B6.B7.C8.B9.C10.A Passage 7 Cloze 6 1.A2.C3.B4.B 1.B2.C3.A4.C5.B6.A7.A8.C9.A10.A Passage 8 Cloze 7 1.B2.C3.B4.A 1.C2.A3.B4C5.A6.A7.B8.A9.C10.B Passage 9 Cloze 8 1.C2.A3.B4.B 1.C2.A3.B4.B5.A6.C7.C8.A9.C10.C Passage 10 Cloze 9 1.C2.B3.A4.A 1.A2.B3.A4.A5.C6.B7.C8.A9.C10.B Passage 11 题型二选择型阅读理解 1.A2.B3.B4.C Passage 12 Passage 1 1.B2.C3.A4.C 1.C2.A3.C4.A 第四部分 重难语篇巩固练 题型一还原型阅读理解 Passage 3 1.A2.E3.F4.B5.D Passage 1 Passage 4 1.D2.B3.F4.A5.E 1.F2.D3.E4.C5.A Passage 2 Passage 5 1.D2.E3.B4.C5.F 1.A2.D3.B4.E5.F 10
