9、,D）中，选出最佳选项。AThe Thomas Fire was the biggest wildfire California had ever experienced-at the time.Itpainted the sky orange and brown,ash falling over a wide area.Tanika Ladd,a graduate student at the University of California wondered how the ash mightaffect marine(海洋的)life offshore.So she collected
10、some ash and took the samples to the lab tofind out.The tests suggest that nutrients from the ash could promote phytoplankton growth,particularly during times of the year when the ocean is short of nutrients.Tiny floating organisms,called phytoplankton,rarely have the nutrients they need to grow inm
11、uch of the ocean,and they take nutrients from wherever they can find them,even fromatmospheric sources.Past studies on volcanoes have revealed how eruptions pumping iron-richash into the atmosphere could feed phytoplankton downwind,and dust from the Sahara has longbeen recognized as a“sandy fertiliz
12、er”for ocean plants.However,much less attention has beenpaid to the impact of wildfire ash.Ladd and her colleagues mixed the ash with seawater in the lab.Then the researchers enrichedtanks full of naturally occurring marine phytoplankton communities and let them grow outside innatural light conditio
13、ns.At four different times over a week,they measured biomass and nutrientsin the water.They repeated the experiment during each season.In the experiments,the phytoplankton greedily sucked up the available nitrogen coming off theash.The additional nitrogen helped phytoplankton communities grow more d
14、uring the summer,fall,and winter.Phytoplankton in the spring,on the other hand,showed less of an effect since theocean has a flood of nutrients in the spring,Ladd noted that the study is one of the first to link wildfire ash and marine systems,but manyunknowns remain,such as the amount of ash deposi
15、ted and what happens to it when it settles ontheocean.Ladd plans to analyze the phytoplanktons DNA to see whether the ash benefitscertain species more than others.In an introductory analysis,Ladd found that the ash did not seemto change the abundance of one particular type of phytoplankton,but furth
16、er analysis is needed.21.What did the researchers do in the experiments?A.Theyprovidedphytoplanktoninthetankswithasandyfertilizer.B.They kept a regular record of biomass and nutrients in the tanks,C.They exposed phytoplankton in the tanks to strong tight.D.They mixed volcanic ash and seawater in the
17、 tanks.22.What might Ladd do next?A.Fully explore the composition of wildfire ash.B.Calculate the amount of deposited wildfire ash.C.Find out what happens after the ash falls on the ocean.D.Further test whether the ash gives certain species an advantage.23.What might be the best title for the text?A
18、.Wildfire ash is choking marine life.B.Wildfire ash feeds the oceans tiny life formsC.Marine atmospheric environment fuels the wildfires.D.Marine animals are suffering from a shortage of nutrients.BIn an office building of Helsinki,Finland，a social worker is meeting six elderly people forlunch-via t
19、ablets propped on their kitchen tables.While many countries with growing elderlypopulations are building new care homes,Finland is looking after people in their own homes-bymeans of technology.The most common reason for a home visit by a social worker is to check that Grandma is takingher medicine.A
20、 pill-dispensing(配药的)robot in her home can do that.Each holds a two-weeksupply of multiple drugs,gives a reminder when it is time to take them and dispenses the rightcombination.For one in five people who try them the robots dont work,usually because Grandmais reluctant to take lots of pills.But for
21、 the rest,they have cut medication-related visits from 30 tojust four a month.The idea of old folk living alone perhaps worries Finnish people less than many others;Finnspride themselves on their rugged self-reliance.A welcome pack for foreign journalists includes abook of cartoons depicting“Finnish
22、 nightmares”,such as having to say“hello”to a neighbour.Social isolation,however,is a big problem for the elderly because it leads to faster cognitive andphysical decline.To deal with that,Helsinki runs virtual get-togethers for its homebound elderly.These should be regarded as extras,though.A degre
23、e of personal interaction,not just the virtualkind,is surely necessary even for Finns.The biggest challenge for both humans and devices is to spot problems early.Local techcompanies,including MariCare Oy and Benete,have developed systems to gather data on thingslike how often a person visits the bat
24、hroom or opens the fridge.Care workers use such data toprioritise whom to visit and what to check for.Not opening the fridge as often,for example,is ahint that memory problems may be getting worse.The biggest gain from technology may be that it makes it easier to keep old people fit enough toremain
25、in their own homes.This is much cheaper,and usually nicer,too.24.How does Finland look after its elderlyA.By building more new care homes.B.By offering them remote-care services.C.By increasing the population of social workers.D.By creating more senior-accessible public areas.25.How can a pill-dispe
26、nsing robot help?A.It comforts the elderly reluctant to take pills.B.It reminds nurses to restore an elderlys drug supply.C.It ensures the doctors give the right combination of pills.D.It saves social workers the trouble of frequent home visits.26.What might the author suggest the Finns do?A.Make so
27、me face-to-face contact.B.Stick to their tradition of self-reliance.C.Run as many virtual get-togethers as possible.D.Keep a safe social distance with their neighbours.27.What is a shared goal of MariCare Oy and Benete?A.Freeing the homebound elderly from restrictions.B.Helping the elderly suffer le
28、ss from memory loss.C.Identifying potential health problems of the elderly.D.Developing household systems suitable for the elderly.CSince apps like Uber and Lyft came on the scene,ridesharing services have dramatically changedthe way people get around.A new study out of Columbia University reveals a
29、 downside of theseservices.It turns out that ridesharing trips cause an increase in the number of accidents involvingmotorists and pedestrians at pick-up and drop-off locations.Previous studies on the relationship between ridesharing services and vehicle crashes comparecities where ridesharing servi
30、ces are available with cities where they are not,and this makesresults somewhat ambiguous.In this study researchers analyze individual trips to make the picturea little clearer.Researchers analyzed data from 372 million ridesharing trips in New York City between 2017and 2018.Whenever a crash occurre
31、d in the city,they calculated the number of ridesharing tripsthat began or ended in the area at the time of the accident.They compared this with the number oftrips that took place in the same location one week before and one week after the crash.Researchers did the same calculations for regular taxi
32、 rides as part of their analyses.Also,separateanalyses were performed based on the type of people injured in the crash:pedestrians,motorists orcyclists.The results of the analyses show that the rise in ridesharing trips is associated with an increasein the number of accidents involving pedestrians a
33、nd motorists,but not cyclists.Furthermore,theydid not find this same association between taxi trips and accidents.“Ridesharing is changing the way we move around cities.”says first author ChristopherMorrison.“It is becoming clear that the technology reduces alcohol-related crashes，but thesebenefits
34、do not seem to extend to the overall number of crashes.These findings help explain whythat might be because the reductions in alcohol-related crashes are offset by increases inother types of crashes.”Researchers hope that cities and ridesharing services will use the results of this study to rakemeas
35、ures that might reduce the number of crashes.“In crowded areas with large numbers ofrideshare pick-ups and drop-offs,cities could consider building taxi-rank style infrastructure(基础设施)to protect pedestrians and prevent crashes.”concludes Morrison.28.What do we know about previous studies on rideshar
36、ing services?A.Their analysis is hardly reliable.B.Their findings are rather ridiculous,C.Their research method is out-of-date.D.Their research sample is not wide enough.29.What can be said about the number of ridesharing trips a week before a vehicle-pedestriancrash?A.It was uncertain.B.It was rela
37、tively low.C.It was unexpectedly high.D.It was the same as a week later.30.What fact does the underlined word“that”in Paragraph 5 refer to?A.Ridesharing reduces alcohol-related crashes.B.Ridesharing doesnt increase accidents involving cyclists.C.Various types of crashes increase with ridesharing ser
38、vices,D.Overall crashes dont decrease along with alcohol-related crashes.31.What does Morrison suggest in the last paragraph?A.Improving infrastructure to expand taxi services.B.Banning ridesharing services in crowded places.C.Constructing some stops for ridesharing vehicles.D.Reducing the number of
39、 pick-ups and drop-offs.DIn the good old days,gold miners could seek out visible spots of bling at the surface in order tofind deeper,richer veins(矿脉).These days,prospectors must examine samples of dirt for moreminute traces suggestive of a hidden mine below.Analysing water from boreholes(钻孔)can als
40、oprovide clues,but boreholes are scarce and new ones are costly and time-consuming to drill.Trees offer an alternative that has come off in Australia.The idea has been around since the1940s but,until now,never practical.Some trees have roots that reach deep underground,drawingup water and,along with
41、 it,tiny quantities of minerals that end up distributed throughout the tree.In this way,even lofty leaves bear traces of what lies far beneath.In areas where there is no gold.leaves may have a background level of 0.15 parts per billion(ppb)of gold;on gold-rich sites thatcan rise to 4ppb.In proof-of-
42、principle studies over the last few years,Nathan Reid and his team at CSIRO,Australia s national science agency.have shown that biogeochemical prospecting closely agreeswith the surface and groundwater analyses.Inspired by these results.Marmota,an explorationfirm,put the method to the test at its Au
43、rora Tank site,50km from the highly-productiveChallenger mine in South Australia.Leaves collected immediately around a known deposit that lies beneath ten metres of rockcontained traces of gold.Further samples were taken 40 metres apart around known deposits.andat wider spaces farther out.This turne
44、d up several anomalies,where gold seemed to be present butother tests had shown nothing.“usual surface sample testing was saying Dont drill here,”saysColin Rose,Marmotas executive chairman.“but the tree sampling was saying Drill here.”Thencame the pay-off.Drilling revealed a five-metre-thick vein wi
45、th 27g of gold per tonne,more than30 metres below the surface.Ametre-thick inner layer held an impressive 105g per tonne.Marmota is keen to explore further.Prospecting with trees is starting to look less like ascientific curiosity and more like a golden opportunity.32.What is Paragraph l mainly abou
46、t?.A.Challenges facing previous gold miners.B.Important clues about richer gold veins.C.Conventional ways of gold prospecting.D.Problems brought by drilling boreholes.33.What does the underlined part“come off”in Paragraph 2 mean?A.Produced an unexpected outcomeB.Obtained a successful resultC.Reached
