7、 on a budget, you will probably choose to _Alisten to symphonic and choral musicBappreciate dramatic plays with your childrenCwatch Antonio Salieris Europa RiconosciutaDenjoy classical dramas at Italy s first public playhouse3What is attractive about Teatro Manzoni?AIts unique design style.BIts easy

8、 access to performers.CIts wide range of shows.DIts requirements for the actors lines.BI remember a basketball game on our homecourt at Senn High School in Chicago.The kids from my school began booing (向喝倒彩) the visiting team.After a minute or two, Senns coach, Cap Leighton instructed us that booing

9、 the other team was impolite and therefore unacceptable, and it needed to stop immediately.Such was Coach Leightons authority that it did stop straightaway.For the rest of the game we restricted ourselves to cheering on our own team.How many people remember sportsmanship? I remember it and now think

10、 of it chiefly as something missing from contemporary sports.Sportsmanship was once central to tennis.The famous players, such as the great Australian generation of Rod Laver, Ken Rosewall, and John Newcombe, set an example for us.Harry Hopman, the Australian Davis Cup coach between 1939 and 1967, m

11、ight send a player home for saying dirty words on the court.However, some players dealt a blow to sportsmanship with their bad behavior on the court in the name of heightened competitiveness.And its rude of me perhaps to point this out on the weekend of the Super Bowl, but no sport has become more b

12、ereft (失去的) of sportsmanship than football generally and professional football in particular.There is what is sometimes referred to as the 12th man in football.This 12th man is the home crowd who begin a burst of uninterrupted screaming when the visiting team has the ball, so that its quarterback ca

13、nt hear instructions from the sidelines and his teammates cant hear his signal calling at the line of mixed fight.Sportsmanship matters because without it sports are an empty proposition (命题).Sportsmanship implies respect for the game, for your opponent and for yourself.A great part of the justifica

14、tion (理由) for sports is that its a forcinghouse for building character.Accepting defeat with grace is one of sportsmanships characterbuilding components.Without sportsmanship, sports are little more than grown men playing childrens games.4How does the author introduce the topic in the text?ABy listi

15、ng some evidence.BBy presenting an argument.CBy comparing different views.DBy recalling his past experience.5The players and the coach are mentioned in Paragraph 2 to show _Athey fully practiced sportsmanshipBthey advertised Australian Davis CupCtennis players had to obey strict rulesDtennis was an

16、influential sport in Australia 6Which sport valued sportsmanship the least according to the author?ABasketball.BTennis.CFootball. DBaseball.7What does the author intend to do in the last paragraph? ATo encourage us to accept defeat bravely.BTo appeal to us to live up to sportsmanship.CTo call on us

17、to seek ways to encourage sportsmanship.DTo advise us to explore the components of sportsmanship.CPolyurethanes durability (耐久性) has made it a desirable material in many industries that rely on its flexibility and light weight to massproduce things.But its long length of service also makes it extrem

18、ely difficult to break down or be recycled into new products.Therefore, many tons of polyurethane plastics end up in waste fields, where they pile up for decades, harming the health of wild animals and humans alike.For most creatures, the buildup of polyurethane plastics means only bad news.But at l

19、east one of Earths organisms sees them as a favor: a kind of bacterium called Pseudomonas sp.TDAl that appears to love eating some parts of this kind of plastics.This organism seems to grow well in waste fields.Other plasticchewing bacteria have been discovered before, but each seems to have their o

20、wn taste in types of chemicals they prefer to break down.Pseudomonas sp.TDAl is one of only a few organisms known to be tolerant to the plastics typically poisonous characters.Whats more, the bacterium doesnt just survive the plastics unpleasant ingredients (成分)：It uses some of them as a food source

21、.“While there is still much work to be done, this is exciting and necessary research that shows the power of valuable biocatalysts (生物催化剂) found in nature，” John McGeehan, the director of the Centre for Enzyme Innovation said.“Understanding and using such natural processes will open the door for new

22、 recycling solutions.”Mass microbial (微生物的) cleanups of plastics arent necessarily possible in our future, however.The bacterium doesnt seem able to break down these products completely.But the study author Hermann JHeipieper hopes that indepth studies of Pseudomonas sp.TDAl will uncover the genes c

23、rucial to these plasticattacking abilities.Understanding how these genes and their products work could help scientists engineer environmentallyfriendly approaches to handling plastics in the future.In the meantime, Heipieper stresses the importance of not worsening the plastic issue.As he tells The

24、Guardian, “The main message should be to avoid using plastics which are later thrown into the environment in the first place.”8What do we learn about polyurethane from Paragraph 1?AIts recycling takes decades.BIt is not commonly seen in life.CIt is not massproduced in many industries.DIts durability

25、 makes it a doubleedged sword.9Why did Pseudomonas sp.TDAl draw scientists attention?ABecause it makes plastics less poisonous.BBecause it feeds on polyurethane plastics.CBecause it has a special taste for chemicals.DBecause it removes plastics unpleasant ingredients.10What do John McGeehans words i

26、n Paragraph 4 mainly reflect?AThe breakthrough in plastic recycling.BThe process of developing biocatalysts.CThe reliability of new recycling solutions.DThe significance of recycling used things.11Whats Heipiepers recommended way of handling plastic pollution?ARecycling plastics in a green way.BFind

27、ing more valuable biocatalysts.CUsing fewer plastics in our daily life.DSetting up strict standards for producing plastics.DCities across America have set up bikeshare programs as sustainable(可持续的) transportation alternatives to ease traffic jams.Yet despite these programs advantages and popularity,

28、 significant operational challenges remain.Residential neighborhoods face shortages of bicycles in the morning rush hour, while business districts have a lack of bikes in the evening.Whats more, parking docks can be full at certain hours when riders have reached their destinations.Currently, many sy

29、stems rebalance their bike supply using box trucks that reallocate dozens of bikes at a given time.This is a costly, timeconsuming attempt that enlarges the systems carbon footprint.Thus, it is vital that rebalancing be as efficient as possible.With that in mind, my colleagues and I set out to devel

30、op advanced algorithms (算法) to deal with the novel challenges of bikeshare operations.One area to which our methods were applied was the Bike Angels program that our collaborators run in cities across the country.Initially, riders of Bike Angels earn points by renting or returning bikes at certain h

31、ighneed stations.In a study, we found that these fixed patterns cause inefficiencies when returns are incentivized(激励) in locations where they do not actually help with rebalancing.The changes to operational patterns we made based on our algorithms can increase the efficiency of the incentives by ar

32、ound 15 percent.And importantly, this form of rebalancing comes with a much better carbon footprint than box trucks!Our algorithms are applied for other purposes, too.For instance, by analyzing usage information, we were able to help operators make accurate determinations about whether they need to

33、send out crews to fix a broken bike or dock as well as dealing with maintenance (维修) issues in a timely manner.To be sure, algorithms cant fix every new transportation problem and they have many limitations.But what is clear is that many challenges that come with new options, including ebikes and fr

34、eefloating bikeshare systems, require the realtime datadriven approaches.12What can we learn about bikeshare programs in Paragraph 1?AThey have many drawbacks.BThey add a burden to city traffic.CThey work much better in business districts.DThey increase the popularity of sharing economy.13What does

35、the underlined word “that” in Paragraph 2 probably refer to?AHow to reduce box trucks carbon footprint.BHow to use box trucks to reallocate bike.CHow to rebalance bike supply efficiently.DHow to help riders earn more points.14Which of the following shows the advantages of the authors algorithms?Incr

36、easing boxtruck compames profit.Improving the effectiveness of incentives.Providing more incentives for regular cyclists.Making bike reallocation more environmentally friendly.Making the maintenance of bikes more timely and accurate.ABC D15What can be the suitable title for the text?ACreative approa

37、ches to easing traffic jamsBAdvantages of developing advanced algorithmsCAn introduction of Bike Angels incentive systemDAn effective solution to bikeshare operational problems.阅读七选五Alexander Miles is an AfricanAmerican inventor who is largely known for his contribution to the elevator industry.He w
