become known as Apple),then he went on to start up two other successful companies,before returning to Apple,where he created the iPhone,the product that many consider to be the most significant invention of this century.SAL KHANThen,we have the owner of one of the biggest online education providers,Khan Academy.He may not be as famous as the other two,but his contribution to education deserves as much ing his website,anyone can have unlimited access to educational videos for free,allowing people to gain in-depth knowledge about many subjects without attending a formal course.For this,he is on the list of the 100 most influential people in the world.Their stories will continue to inspire and create new leaders who aspire to attain success regardless of their wealth or circumstances.1.Who is a perfect examp le to show “Born poor,one can still succeed”?A.Sal Khan.B.Steve Jobs.C.Sundar Pichai.D.All of them.2.Why is Steve Jobs’ life like a roller coaster?A.Because he likes roller coasters.B.Because his life is full of ups and downs.C.Because he started two other successful companies.D.Because he was fired by the company that he co-founded.3.What causes Sal Khan to

people with access to various knowledge free of charge.D.His product is considered to be the most significant invention of this century.B(甘肃张掖高一期末)When she first started learning about the climate change from one of her elders,Fawn Sharp was invited on a helicopter flight over the Olympic Mountains to survey the Mount Anderson glacier.But the glacier was gone,melted by the warming climate.Sharp had a deep sense of loss when she disc overed the glacier wasn’t there anymore.Loss is a growing issue for people working and living on the front lines of climate change.And that gave Jennifer Wren Atkinson,a full-time lecturer at the University of Washington Bothell,US,an idea for a class.This term,she taught students on the Bothell campus about the emotional burdens of environmental studies.She used the eerican tribes(部落),scientists and activists,and asked her 24 students to face the reality that there is no easy fix—that “this is such anintractable problem that they’re going to be dealing with it for the rest of their lives”.Student Cody Dillon used to be a climate science skeptic(怀疑论者).Then he did his own reading and research,and changed his mind.Dillon wasn’t going into environmental wo rk—he was a computer-science major.Yet,the potential for a worldwide environmental catastrophe seemed so real to him five years ago that he quit his job and became a full-time volunteer for an environmental group that worked on restoration(恢复) projects.Si x months into the work,he decided that Atkinson’s class was just what he was looking for—a place where he could discuss his concerns about a changing climate.Atkinson said she hoped the class helped her students prepare themselves for the amount of environmental loss that would happen over their lifetimes.“We are already changing the planet—so many species are going to be lost,displaced or massively impacted,” she said.“The future isn’t going to be what they imagined.”4.Why did the author mention the case of Fawn Sharp?A.To lay a basis for Fawn Sharp’s further research.B.To prove Fawn Sharp’s work is similar to Atkinson’s.C.To lead into the issue of loss caused by climate change.D.To show scientists’

environment.C(山东德州高一期末)To solve a big environmental problem,chemists have been thinking small.Really small:a new mini robot with the purpose of helping clean up tiny plastic polluting water across the globe.The new microrobots,each of which is no bigger than the tip of a pencil,are magnetic(磁性的) and shaped like four-pointed stars.When the sunlight shines on them,they can swim in a specific direction;when the sunlight disappears,they stop moving.Finding a piece of plastic,they hold onto it,produce chemical reactions and start to break it down.The project is led by chemist Martin Pumera,a researcher who also studies ways to build microrobots at the Czech University in Prague.About ten years ago,he noticed the microplastic was everywhere,from the bottom of the ocean to the ice on the top of mountains.It even turned up in drinking water,both bottled and tap water.Just think about how much plastic you encounter every day.It doesn’t easily degrade(降解),which is a bigproblem.Therefore,Pumera chose to focus on the problem of water pollution caused by microplastic.The researchers tested the microrobots on four types of plastic in the lab.After a week,all four began degrading,losing between 0.5 and 3 percent of their weight,which indicated they were breaking down.The robots also turned the plastic’s smooth surface into rough.Finally,they could be collected for reuse along with the plastic waste without causing new pollution.In fact,Pumera says they still have a long way to go.These microrobots are unlikely to succeed in degrading all types of plas tics.They’ll also need a lot of testing to show that they’resafe in open waterways,such as at sea.But he thinks that these challenges can be overcome.Someday,the microrobots will play a big role in a worldwide cleanup effort.8.What can be learned about the new microrobot?A.It is of a round shape.B.It is as small as a pencil.C.It is driven by sunlight.D.It uses physical reaction.9.What inspired Pumera to design the microrobot?A.The ice on the mountains.B.Secrets of the ocean bottom.C.The lack of drinking water.D.The microplastic pollution.10.How does a microrobot deal with the plastic?A.Collecting it for reuse.B.Making its surface smooth.C.Absorbing it completely.D.Breaking it down to some eera’s attitude to their future research?A.Doubtful.B.Confident.C.Regretful.D.Critical.DAnne Smith teaches science at a high school.This past spring,she gave students in her 9th-grade physic class tools and a light bulb and said,“Have a go.See if you can make the bulb light up.”Smith sees value in letting her students experiment.She selects activities that may have more than one answer.Then she encourages students to try different approaches to solving a problem.“The point,” Smith says,“is to eethods tried.” In doing so,students learn to value mistakes.Thomas Edison once wanted to make a better battery.But after working for over five months,he still didn’t succeed.He told a friend,Walter S.Mallory,that he had already done more than 9,000 ealloy replied,“Isn’t it a shame that with the huge amount of wo rk you have done you haven’t been able to get any results?” Edison replied with a smile,“Results!I have gotten a lot of results!I know several thousand things that won’t work.” Eventually,the inventor got the new battery to work.He patented it,too.The means of Smith and Edison is different from the way science is carried out in most classrooms.Schools tend to focus on covering lots of topics and memorizing countless facts.Many classes rely on teuch information as possible.The problem with thosebooks,explains Stuart Firestein,who studies biological sciences at Columbia University,is that “they have no conteents but don’t tell us why people did them.Nor do they describe experiments that didn’t work.“By focusing on successful outcomes,”Firestein says,“we leave out 90 percent of science.”When we fail,we question thoughts,opinions and ideas.Through such questions,we connect ideas and challenge reasoning.Both skills are highly valued by a scientist,says Firestein.Learning about failures also makes science more approachable.Science is not just talented people making one discovery after another.Rather,the history of science is full of mistakes and wrong turns.12.What is the role of mentioning Smith’s science class?A.To tell the background knowledge.B.To introduce the topic of the teend a new teaching method.13.Why does Smith select activities with open answers?A.She wants students to learn through experiments.B.She eistakes.C.She wishes students to do many experiments.D.She likes to lead students to their own conclusion.14.What does Firestein mean by saying “we leave out 90 percent of science”?A.Textbooks should get updated regularly.B.Schools should pay attention to science education.C.Students should value the experiment process.D.Science learning should include the study of failures.15.What is the main purpose of the text?A.To introduce several experts in science.B.To encourage students to accept failures.C.To stress the importance of failures in science.D.To compare different experimental approaches.第二节(共5小题;每小题2.5分,满分12.5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。
