9、 ever to be elected president of the AMA.Harris grew up in a small town,and becoming a doctor felt like a dream for her.“Even though I knew I wanted to be a physician,” she said,“I had no idea how to get there.” Harris worked extremely hard to achieve her dream.She said,“In life,none of us get throu
10、gh without any setback.Whats important is to learn from these challenges.” Harris completed her undergraduate and graduate studies at West Virginia University.When Harris was in her third year of medical school,she decided to specialize in psychiatry(精神病学),the study and treatment of mental illnesses
11、.“Some of my patients had what I thought were very interesting disorders,” she said.“And there was something new every day.”In 2007,Harris won the Psychiatrist of the Year Award and widely recognized as a top doctor.But it is not awards,she said,but rather treating and caring for her patients that h
12、as motivated her throughout her career.“That interaction with my patients is very fulfilling,because every opportunity that I have to help a patient in need is so meaningful,and it shows me why I originally wanted to go into the profession of medicine,” Harris said.As president,Harris hopes to make
13、sure that people across the country have access to the resources they need to ensure good health and that everyone is on a path.She said,“Everyone should have the same opportunities to live a healthy life.”4.What can we learn about Patrice Harris from Paragraph 1?A.She is talented as a physician.B.S

16、February 18,2021,with a picture-perfect landing inside the Jezero Crater.The car-sized,six-wheeled rover,nicknamed Percy,is the US space agencys biggest and most advanced explorer to date.Its primary mission is to search for signs of ancient microbial(微生物的) life on Mars.Landing on Mars is extremely
17、tricky.The Red Planets gravitational(引力的) pull causes approaching spacecraft to go faster to high speeds,while its thin atmospherejust 1 percent that of Earthsdoes little to help slow it down as it approaches the surface.The scientists had to reduce Percys 12,000 mph speed to a safe landing speed of
18、 less than five mphin just six and a half minutes.The target entry angle also had to be a precise 12 degreesany steeper,and the spacecraft would burn up;any flatter,and it would get lost in space.It is no wonder that the final approach is often referred to as the “seven minutes of terror”.Upon attai
19、ning a manageable speed,Percy briefly flew over the Martian surface to seek out the perfect landing spot.Its complex map-reading system rapidly scanned the area and matched it with maps in its database to find the best location.The NASA scientists will spend the next two months testing Percys scient
20、ific instruments.Once ready,the rover will begin to carry out its mission.“Perseverance is the smartest robot ever made,but confirming that microbial life once existed carries an unusually large burden of proof,” said Lori Glaze,director of NASAs Planetary Science Division.“While well learn a lot wi
21、th the great instruments we have aboard the rover,it may very well require the far more well-equipped laboratories and delicate instruments back here on Earth to tell us whether our samples (样本) carry evidence that Mars once harbored life.”8.What is the extraordinary challenge for the rover to land
22、on Mars?A.The speed reduction.B.The atmosphere analysis.C.The location search.D.The time management.9.What is Paragraph 3 mainly about?A.Ways to find the precise entry angle.B.Consequences of wrong entry degree.C.Factors to survive “the seven minutes”.D.Reasons for the necessity of speed reducing.10
23、.What does “it” refer to in Paragraph 4?A.The spot.B.The area.C.The system.D.The surface.11.What can be inferred from Lori Glazes words?A.Instruments aboard the rover are not quite reliable.B.Perseverance is able to collect enough evidence needed.C.Man still has a long way to go to prove life was on
24、 Mars.D.Samples of Mars will be returned soon to our labs on Earth.DAnyone who commutes(通勤) by car knows that traffic jams are an unavoidable part of life.But humans are not alone in facing potential jams.Ants also commutebetween their nests and sources of food.The survival of their colonies depends
25、 on doing this efficiently.When humans commute,theres a point at which cars become dense (稠密的) enough to slow down the flow of traffic,causing a jam.Researchers wanted to know if ants on the move could also get stuck.So they regulated traffic density by constructing bridges of various widths between
26、 a colony of Argentine ants and a source of food.Then they waited and watched,trying to find out at what point they were going to have a traffic jam.But it appeared that that never happened.They always managed to avoid a traffic jam.The flow of ants did increase in the beginning as ants started to f
27、ill the bridge and then leveled off at high density.But it never slowed down or stopped,even when the bridge was nearly filled with ants.The researchers then took a closer look at how the behaviour of individual ants impacted traffic as a whole.And they found that when ants sense overcrowding,they a
28、djust their speeds and avoid entering high-density areas,which prevents jams.Their behaviour may be promoted by pheromones,chemicals that can tell other ants where a trail is.The ants also manage to avoid colliding(碰撞) with each other at high density,which could really slow them down.Can ants help u
29、s solve our own traffic problems?Not likely.Thats because when it comes to getting from point A to point B as fast as possible,human drivers put their own goals first.Individual ants have to be more cooperative in order to feed the colony.But the research could be useful in improving traffic flow fo
30、r self-driving cars,which can be designed to be less like selfish humansand more like ants.12.What does the underlined word“this” in Paragraph 2 refer to?A.Surviving.B.Commuting.C.Finding food.D.Avoiding jams.13.How did the researchers control the traffic density of the commuting ants?A.Through clos
31、er observation.B.By regulating their numbers.C.By finding out the dense points.D.By controlling the widths of their path.14.How can ants avoid traffic jams according to the research?A.They follow a special route.B.They make their flow steady at high density.C.They never stop or slow down on the way.
32、D.They depend on their natural chemicals to make adjustment.15.Which of the following can be the best title for the text?A.Traffic JamsB.Survival of an Ant ColonyC.Unavoidable?Not for Ants!D.Differences Between Humans and Ants.七选五In the workplace,one of the most important skills to possess is good c

43、dextremelyhardtoachieveherdream.Shesaid,Inlife,noneofusgetthroughwithoutanysetback.Whatsimportantistolearnfromthesechallenges.”可知,人的生活中都会有挫折,最重要的是要从这些挑战中去学习,而历经这些挫折加上勤奋才能成功。由此可知,她要把自己的成功归功于从挫折中学习。故选C项。6.B解析推理判断题。根据第三段中“Butitisnotawards,shesaid,butrathertreatingandcaringforherpatientsthathasmotivated
44、herthroughouthercareer.”和“.everyopportunity.professionofmedicine”可知,作为一名医生,是治疗和照顾病人这件事成为她职业生涯的动力,可知她对工作是全心全意的。故选B项。7.D解析词义猜测题。根据第三段中“.becauseeveryopportunitythatIhavetohelpapatientinneedissomeaningful,anditshowsmewhyIoriginallywantedtogointotheprofessionofmedicine”可知,她认为每次有机会帮助病人是很有意义的,由此可见,她认为和病人的互
45、动是值得的,fulfilling与下文meaningful相呼应,故选D项。【语篇导读】本文是一篇说明文。主要介绍了“毅力号”探测器的主要任务,及其登陆火星过程中的情况。8.A解析细节理解题。根据第二段可知,火星引力会使得接近火星的航天器更快速行进,并且火星稀薄的大气层对减缓航天器的速度几乎没有帮助,故减速是“毅力号”探测器登陆火星的特别挑战。故选A项。9.C解析主旨大意题。通读第三段内容可知,该段尾句“Itisnowonderthatthefinalapproachisoftenreferredtoasthesevenminutesofterror.”为本段总结句,再结合该段上文可知,该段主
