2、 methane by breaking down the grass,Now scientists have shown that the pollution fromcows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago.But thiswork was done in a laboratory,there were many quest
3、ions about whether the idea could work in real life.In the lab studies,the cows were given quite a bit of seaweed,and they would cause losing weight.Thatwasnt helpful,since cows are often sold by weight.It also wasnt clear if the seaweed would stop working if it wasused for a longer period of time.N
4、ow,scientists from the University of California,Davis have answered several of these questions.The researchers studied 21 cows on a farm for about five months.Theytaught the cows to get their foodfrom inside a special hood,which allowed the scientists to measure the methane that the cows were giving
5、 off.This time,they used a much smaller amount of seaweed,which they mixed with the cows food.The results were surprisingly good.In some cases,the cows produced 82%less methane.The improvementdepended on the kind of food the cows were given,but even the worst-polluting cows produced 33%lessmethane.O
6、ver the five months,the scientists didnt see any signs that the cows stomachs were getting used to theseaweed and starting to produce more methane again.Another surprise came when they looked at the weight of the cows.The cows that were fed seaweed gainedjust as much weight as the other cows,but the
7、y didnt need as much food.But there are still some big problems with the idea of feeding cows seaweed.For one thing,theresnotadequateseaweed to feed all of the cows in the world.So farmers would have to figure out a way to grow lotsof seaweed.A bigger problem is that for most of their lives,cows liv
8、e in fields,where they eat the grass.That meanstheres no chance to feed them seaweed every day.These problems need to be taken seriously if the world isgoing to avoid the worst effects of the climate crisis.Still,its true that something as simple as feeding cows seaweed can help reduce some of the p
9、ollutioncausing the climate crisis.1.Why did the scientists do the experiment on the farm?A.To control the amount of seaweed.B.To record the weight cows gained.C.To confirm the effect of seaweed in real life.D.To measure the amount of seaweed cows ale.2.The underlined word“adequate”means _.A.commonB
10、.specialC.lackingD.enough3.The passage is written to _.A.appeal to people not to raise the cowsB.encourage people to plant the seaweedC.remind people of controlling cows weightD.call on people to take actions to reduce thepollutionBIs renting clothes greener than buying them?Sustainable(可持续的)fashion
11、 expert Elizabeth Cline isnt sure.Clothing renting is a hot new industry and businessmen are trying to attract shoppers who care about theenvironment.Last summer alone,Urban Outfitters,Macys,Bloomingdales American EagleandBanana Republicallannounced renting services a sure sign of changing times.But
12、 is renting fashion actually more environmentally-friendly than buying it?And if so,how much more?Journalist and author Elizabeth Cline researched this question in a feature article for Elle,and she concluded thatits not as sustainable as it seems.Take shipping for example,which has to go two ways i
13、f an item is rented receiving and returning.Clinewrites that consumer transportation has the second largest carbon footprint of our collective fashion habit aftermanufacturing.Then theres the burden of washing,which has to happen for every item when its returned,regardless ofwhether or not it was wo
14、rn.For most renting services,this usually means dry-cleaning,which is a pollutingprocess.All the renting services that Cline looked into have replaced perchloroethylene,a carcinogenic(致癌的)air pollutants thats still used by 70 percent of US dry cleaners,with hydrocarbon(碳氢化合物)alternatives,although th
15、ese arent great either.They can produce harmful waste and air pollution if not handled correctly.Lastly,Cline fears that renting services will increase our appetite for fast fashion,simply because its so easilyaccessible.Theres something called“share-washing”that makes people have more wasteful beha
16、viors because aproduct or service is shared and thus is considered more eco-friendly.Uber is one example of this:advertised as away to share rides and reduce car ownership,and yet it has been proven to discourage walking,bicycling andpublic transportation use.Renting clothes is still preferable to b
17、uying them cheap and throwing them into the bin after wearing them afew times,but we shouldnt let the availability of these services make us self-satisfied.Theres an even better step and thats wearing what we already have.4.What do we know about Elizabeth Cline from the passage?A.She is trying to at
18、tract shoppers.B.She is an expert and journalist.C.She has created“share-washing”.D.She never rents clothes.5.Why does renting services increase peoples appetite for fast fashion?A.Because it is handled correctly.B.Because it is transported easily.C.Because it is fairly eco-friendly.D.Because it is

20、obably come from?A.Environment.B.Technology.C.Travel.D.Medicine.CWolves have a certain undeserved reputation:fierce,dangerous,good forhuntingdown deer and farmerslivestock.However,wolves have a softer,more social side,one that has been embraced by a heart-warming newinitiative.In a bid to save some
21、of Europes last wolves,scientists have explored the willingness of these supposedlyfierce creatures to help others of their kind.Female wolves,the scientists have discovered,make excellent fosterparents to wolf cubs that are not their own.The study,published in Zoo Biology,suggests that captive-bred
22、wolfcubs(幼兽)could be placed with wild wolf families,boosting the wild population.The gray wolf was once the worlds most widely distributed mammal,but it became extinct as a result ofwidespread habitat destruction and the deliberate killing of wolves suspectedof preying on livestock.Fear andhatred of
23、 the wolf have since become culturally rooted,fuelled by myths,fables and stories.In Scandinavia,the gray wolf is endangered,the remaining population found by just five animals.As aresult,European wolves are severely inbred and have little geneticvariability（变异性）,making them vulnerable tothreats,suc
24、h as outbreaks of disease that they cant adapt to quickly.So Inger Scharis and Mats Amundin ofLinkoping University,in Sweden,started Europes first gray wolf-fostering program.They worked with wolveskeptat seven zoos across Scandinavia.Eight wolf cubs between four and six days old were removed from t
25、heirnatural parents and placed with other wolf packs in other zoos.The foster mothers accepted the new cubs placedin their midst.The welfare of the foster cubs and the wolves natural behavior were monitored using a system ofsurveillance cameras.The foster cubs had a similar growth rate as their step
26、 siblings in the recipient litter,as wellas their biological siblings in the source litter.The foster cubs had a better overall survival rate,with 73%survivinguntil 33 weeks,than their biological siblings left behind,of which 63%survived.That rate of survival is similar tothat seen in wild wolf cubs
27、.Scientists believe that wolves can recognize their young,but this study suggests theycan only do so once cubs are somewhere between three to seven weeks of age.If captive-bred cubs can be placed with wild-living families,which already have cubs of a similar age,not onlywill they have a good chance
28、of survival,but they could help dramatically increase the diversity of the wildpopulation,say the researchers.Just like the wild wolves they would join,these foster cubs would need protectionfrom hunting.Their arrival could help preserve the future of one of natures most iconic and polarizing animal
