参考译文Unit 1课文A石油1油，和煤一样，存在于沉积岩中，而且可能由死去很长时间的生物有机体形成。
含有石油的岩石几乎都来源于海洋，所以形成石油的有机物一定是海洋生物，而不是树木。
2 石油，并不是来自于逐渐积聚的木质物质，而可能是来自于逐渐积聚的海洋生物的脂肪物质。
比如浮游生物：大量浮游在海水表层的单细胞生物。
3 有机物的脂肪物质主要由碳氢原子组成，因此并不需要太多的化学变化就可以形成石油。
生物有机体只需在缺氧的条件下沉积到海湾浅水处的淤泥里。
其脂肪不是分解腐烂，而是逐渐积聚，并在深层的淤泥里圈闭起来，进而经过细微的原子重组，最终形成石油。
4 油比水轻，呈液态，会经由上方覆盖的孔隙性岩石向上渗透，在地球上有些地区到达表层，古人将这些表层石油称为沥青、柏油或异庚烷。
在古代和中世纪，这些石油油苗常被看作药品而不是燃料。
5 当然，表层的油苗数量很少。
而石油油藏上方有时覆盖的是非孔隙性岩石。
石油向上渗透抵达该岩石，然后在岩石下方逐渐积聚形成油层。
若在上方的岩石上钻个孔，石油就可以通过该孔向上迁移。
有时压力过大，石油会向高空喷出。
1859年在宾夕法尼亚州，由埃德温·德雷克成功打出第一口井。
6 如果可以发现一个合适的地点（勘探人员已经识别出地下可能圈闭有石油的地层结构），那么就很容易抽取这一液体燃料，这要比派人到地下把大块的固体煤炭砍成小块要容易得多。
而且一旦获得石油，可以通过地上管道运输，而不必像煤一样，由运货车经过繁重的装卸任务来运输。
7 石油便于抽取，易于运输，促进了石油的应用。
石油可以蒸馏成不同的馏分，每种馏分均由特定大小的分子组成，分子越小，该馏分就越容易蒸发。
8 到19世纪下半叶，最重要的石油馏分是由中等大小的分子构成的煤油，它不易蒸发，被用于照明。
9 然而，到19世纪末人们研制出了内燃机。
内燃机是通过在汽缸里将空气与可燃气体混合，产生爆炸来提供动力的。
最便利的可燃气体是汽油——石油的又一馏分，由小分子构成，容易蒸发。

四年级下册第二课英语科普版
四年级下册第二课英语科普版English:In the second lesson of the fourth-grade science curriculum, students learn about the water cycle. The water cycle, also known as the hydrological cycle, describes how water moves continuously on Earth. It involves processes such as evaporation, condensation, precipitation, and runoff. Water evaporates from bodies of water like oceans, lakes, and rivers due to heat from the sun. This vapor rises into the atmosphere, where it cools and condenses to form clouds. As the clouds become heavy with water droplets, precipitation occurs in the form of rain, snow, sleet, or hail. This water then flows over the land as runoff, collecting in bodies of water and starting the cycle anew. Understanding the water cycle is essential for comprehending how water sustains life on our planet and how human activities can impact this delicate balance.中文翻译:在四年级科普版的第二课中，学生们学习了关于水循环的知识。

2025年中考英语热点阅读理解---有关环境保护方面
阅读理解(环境保护)1．When you look up at the night sky，what do you see？80% of peoplearound the world see nothing but skyglow （天光，人为白昼现象）.Thisman﹣made brightening of the sky masks the stars.The night sky has played an important role in human life for thousands ofyears.Ancient peoples named the constellations （星座）.Around the sametime，Polynesian sailors used the sun and stars to sail on the sea in the correct ter，the Maya civilization （文明）used the position of the stars to predict the changing of the seasons.But today，few people are able to see sky full of stars.So what happened？Light pollution is the reason.When man﹣made light enters into the night sky，it hides the stars.This excess （过多的）light comes from streetlights，office buildings，stores，flashing billboards，etc.Of course，people in modern societies need to light the night.Nighttime driving，walking，working，exercising，and more are all safer with man﹣made outdoor lighting.However，too much light at night can be harmful.It masks the stars and disturbs our natural sleep patterns，causing greater risk of cancer and heart disease.Light pollution can be greatly reduced （减少）with a few simple actions.The first is to stop wasting light.Outdoor lights can be covered so that the light shines down to the ground only where it's needed.People can be more careful about using lights only when and where they are necessary.Besides，people can choose light bulbs （灯泡）with the smallest effective amount of brightness.Most bright white lights，including LEDs，give off a large amount of shorter﹣wavelength （波长较短的）blue light，which brightens the sky more than any other color of light.Choosing light bulbs with longer﹣wavelength light in yellow or orange can help prevent harmful light pollution.（1）By studying the night sky full of stars，ancient peoples did a lot except .A.naming the constellationsB.sailing on the sea in the correct directionC.predicting the changing of the seasonsD.letting man﹣made light enter into the night sky（2）Today most people can't see the night sky full of stars because of .A.the excess light caused by humansB.the reduction of starsC.the changes in the position of starsD.the influence of weather（3）What does the last paragraph mainly tell us？A.How to save electricity in our daily lives.B.How to choose light bulbs correctly.C.Two ways of reducing light pollution.D.The advantages and disadvantages of man﹣made light.（4）Which of the following statements is NOT true according to the passage？A.Too much light at night can do harm to people's health.B.Man﹣made light hides the stars when it enters into the night sky.C.In ancient times，the night sky played an important role in human life.D.Choosing shorter﹣wavelength blue light can help prevent harmful light pollution.2．Have you ever heard of upcycling？It is a way of turning old or unnecessary things into something useful and often beautiful.Is it the same as recycling？Recycling usually takes old things，like paper and glass，and breaks them down to make a new product.When you upcycle an object，you are probably doing something different.You can simply refashion it.For example，you might make a bag out of an old T﹣shirt.Also，the upcycled object is usually in the same，or even better condition.Upcycling isn't a new idea.Some of the best examples of modern﹣day upcycling come from the old times.In those days，things were repurposed over and over until they were no longer useful.Upcycling is a way of life.Things shouldn't be just thrown away when they can be saved and turned into something useful.It's clear that upcycling is green.It is also considered to be more environmentally friendly than recycling.Upcycling can just require your own ideas and work，but recycling requires energy （能源）or water to break down things.Grace，a young woman from the UK，takes used tea bags and turns them into dresses，shoes and even hats.Every day she drinks some tea，then dries out the tea bags with the tea still in them.When they're dry，she takes the tea out and puts the bags together to make an item of clothing.This can take a long time，but Grace has made lots of artworks.In fact，no matter you create objects from old things or buy ready﹣made products from upcycled things，both ways are helpful for the environment and can bring you something that's both beautiful and useful.Get startedtoday!（1）What does the underlined word "refashion" mean in paragraph 2？A.Break down useless things.B.Collect used things.C.Create things out of old ones.e up with good ideas.（2）How is upcycling different from recycling？A.It's a completely new idea.B.It needs more energy.C.It requires more time and work.D.It's a greener way of life.（3）Why does the writer tell the story of Grace in paragraph 5？A.To list the steps of doing upcycling.B.To give a good example of upcycling.C.To express a different idea of upcycling.D.To provide basic knowledge of upcycling.（4）What is the main purpose of the passage？A.To encourage people to do upcycling.B.To introduce the history of upcycling.C.To compare upcycling with recycling.D.To explain the importance of recycling.3．The school year began.As president of the recycling club，Scott was thinking about new activities to encourage other students to become more enthusiastic（热心的）aboutrecycling.His club had helped to recycle a lot of waste for the past five years and he hoped thatthis year they would do even better.Scott went home one day and looked online，hoping to find ideas for events the club could organize at school.During his research，he learned that the amount（数量）of electronic waste，or e﹣waste，is increasing rapidly.Scott was upset with himself for not noticing this problem sooner.At that moment，he began to develop a plan."There is a special project I want us to work on this term，"Scott announced（宣布）at the recycling club meeting the next day."We have all heard about e﹣waste，but recently I learned about the bad effects it's having on our environment." He went on to tell the club members that he wanted them to organize an e﹣waste drive a day when students and their families could drop off unwanted electronics to be recycled." Now let's get to work!"For several weeks，the recycling club was busy preparing for the upcoming e﹣waste drive，or e﹣drive as it was soon called.The big day finally arrived，and Scott was nervous.He and the other members arrived at school early to make sure that everything would go smoothly.Everyone waited eagerly，hoping that students of the school would take part in the event.It wasn't long before the first cars pulled into the school parking lot.After a while，more people arrived.Phones，TV sets，computers and keyboards soon began piling up（堆积）.At the end of the event，Scott heard someone suggest that the school should have an e﹣drive event every term.Scott smiled，realizing that a simple action could truly have a lasting influence.（1）What did Scott learn during his research online？A.Students are enthusiastic about recycling.B.There is a lot of waste recycled every year.C.The amount of e﹣waste is increasing rapidly.D.There are many recycling clubs in the country.（2）How did Scott feel at first on that big day？A.Proud.B.Upset.C.Excited.D.Nervous.（3）What did Scott realize at the end of the e﹣drive event？A.Environmental problems could be solved.B.A simple action could bring a long﹣term effect.C.Teamwork is valuable for the success of events.D.Family members are interested in school activities.4．How can we stop climate change？How can we stop air pollution？How can we live on a green planet？One way is to use clean energy.Cleanenergy does not harm the Earth.It never runs out.Energy from the Sun is clean.We just need to learn how to get and store more of it.Plants use energy from the Sun.They use it to turn water and air into sugar.The sugar can be used as food.Scientists know a lot about how plants make food.Some scientists want to get energy from the Sun like plants do.They want to make a machine that can use sunlight to make fuel（燃料）from water.Water is made up of two different parts.Breaking water into its parts is hard.Plants do it all the time，though.It is part of how they make food.With energy from the Sun，the new machine will break water into its parts.One of the parts will be used as fuel.Then the fuel is used to make electricity （电）.The electricity can power cars，houses，and so on.This fuel is better for the Earth than gasoline（汽油）.It does not pollute the air.Plants can help us learn how to make clean energy!（1）How does the writer start this article？A.By telling stories.B.By asking questions.C.By comparing facts.D.By giving examples.（2）What will the new machine do？A.Break water into its parts.B.Make some food from plants.C.Turn water and air into sugar.D.Produce sugar as new energy.（3）In which part of a magazine can we read the article？A.Health.B.Society.C.Science.D.History.5．Recycling is good for the environment.It can also do good to a community in surprising ways.Brian，a 15﹣year﹣old boy，knows this well.In 2020，he started a communityrecycling program to offer help to football clubs in his hometown，Wyre.It now has 3，000 participants（参与者）.When Brian was 11，he played football with Fleetwood Town F.C.The club was newand needed money to travel to Premier League （英超联赛）.Brian came up with a plan."There were bottles always thrown around the road，"he said."In Wyre，these can be collected for money."With his father's help，Brian started a bottle drive.Since then，Brian's recycling effort has raised £35，000 and helped at least 20 local youth groups.It has also stopped more than 200，000 bottles from littering the roadside and polluting Wyre'slakes and rivers."It's kept our community a lot cleaner，"he says.In 2023，Brian won The Duke of Edinburgh's Prize for young heroes.The prize goes to kids and teenagers working to help others and protecting Planet Earth."I'm happy to know that all these clubs and kids around the community are benefiting（受益）."Brian says，when asked about all he's finished with his cleanup effort.Brian believes everyone can—and should—be of service."Just do a little bit to help make the world a little bit of a better place，"he says."Be creative，"he adds."Have an idea and build on it."（1）What does the underlined word"It"in Paragraph I refer to（指）？A.The environment.B.Brian's hometown.C.The

Teenagers6．Yushu，Qinghai is one of the habitats for black﹣necked cranes （黑颈鹤）.Cranes have very long necks and their necks are black.That's why they are called black﹣necked cranes.Cranes travel very far every year.Cranes spend about 5 months in Qinghai﹣Tibet Plateau.Starting in March，black﹣necked cranes will fly back to Qinghai.There are lakes and marshes （沼泽），perfect for them to live in.Year after year，black﹣necked cranes may fly to other places，but they always come back to the plateau areas.Their life is harsh，because they have no enough food and the weather changes very often.Black﹣necked cranes have a very small population.They are under first﹣class state protection in China.Local people treat the birds with love.In local tradition，they are a symbol of good luck，so

第15课:Earth and Sky科普英语：Aqua Technology 水资源监测科技
A new weather-monitoring satellite has been 30 years in the making, and some researchers think it's worth the wait. We'll speak with a scientist about the Aqua satellite -- on today's Earth and Sky.
DB: This is Earth and Sky. In May of 2002, NASA launched a state-of-the-art weather satellite called Aqua. It measures temperature and moisture in the atmosphere with highly sensitive infrared and microwave sensors, called sounders.
JB: Aqua circles the globe each day, and along the way it gives scientists a wealth of information about weather and climate cycles. The sounders aboard Aqua require a cooling system to keep temperatures way below freezing, close to minus 270 Celsius, or minus 450 degrees Fahrenheit.
DB: We spoke with Moustafa Chahine, a member of Aqua's science team at the Jet Propulsion Laboratory in Pasadena, California. He said the satellite is working in ways that weren't anticipated.
Moustafa Chahine: We have developed the infrared microwave sounding system to give us the best temperature, the best moisture. Now in looking at it we are finding out that we can determine the amount of carbon dioxide in our own atmosphere and how it is changing. That was never a part of what we were contemplating doing. We can measure the amount of carbon monoxide. We can
measure the amount of methane in our own atmosphere. All of it is coming because of the richness of the data and because of the accuracy with which we are getting it.
JB: For more about the Aqua satellite, come to . Special thanks today to NASA's Earth Science Enterprise. We're Block and Byrd for Earth and Sky.。
