Earth is experiencing its sixth mass extinction：somewhere between 30 and 159 species（物種） disappear every day，and more than 300 types of animals have died out since 1500.This is not good for the future of life on our planet，but what if we could make some of the extinct species come back to life？Thanks to ongoing advances in DNA recovery and cloning technology，de-extinction may soon be realized，and we may see Tasmanian Tigers，or Dodo Birds back into existence in the near future.
Some scientists are confident and optimistic about de-extinction.They think that the best reasons for de-extinction have more to do with ecology than tourism. "If this is always going to be a zoo animal，then stop，" says Ben Novak，the lead researcherat Revive & Restore—a foundation devoted to rescuing endangered and extinct species in San Francisco，California. "The goals have to be about ecological restoration and function."
Take passenger pigeons for example.Their numbers reached nearly 5 billion at the start of the 19th century，and they played an important role in shaping the forests they inhabited（居住）.After their extinction，the forests have never been the same. "The passenger pigeon is a very important ecological species if we want their original habitat back." Novak says.
However，we need to think twice about Novak's idea.Any new scientific initiative is bound to have risks，so is de-extinction.Although some assume that de-extinction may help the environment，we can't be so sure.The de-extinct animals would now be strangers to their habitats.As the habitat is no longer what it was，the species role within the ecosystem may have also changed.This could be actually a threat to the other species within the environment as the de-extinct animals enter the area and compete for food sources.Once again we're trying to force nature to act in a certain way，rather than letting it remain natural.
Many scientists also believe that priorities（優(yōu)先權(quán)） would change within the conservation of currently endangered species.Would we still put in the effort to preserve living animals if we knew we could just magically bring them back from the dead？Douglas McCauley，an ecologist at University of California，Santa Barbara，stresses this worry. "Honestly，the thing that scares me most is that the public absorbs the misimpression that extinction is no longer scary.The general attitude becomes：Deforest，no worry，we can reforest.If we drive something extinct，no worry，we can de-extinct it." said McCauley.
It seems that with the subject of de-extinction，we must look at our reasons for doing such a thing.Yes，we may，in the near future，be able to de-extinct the extinct species.But does that mean we should？Are the risks really worth it？Does it make sense to focus on the dead than the living？And who are we truly benefiting in the end？

1．In 2019，the world generated 54.6 million tons of e-waste.However，just 17.4 percent of it was formally collected and recycled.Since 2014，the amount of e-waste recycled has grown by 1.8 million tons -a relatively small amount，considering that the amount of e-waste generated increased by 9.2 million tons in the same period.
Global reserves of some elements，such as platinum，are supposed to be fully used up within 15 years if the proportion of recycled stocks entering production doesn't increase.E-waste and EV batteries are currently recycled through processes called pyrometallurgy（火法冶金術(shù)）and hydrometallurgy（濕法冶金術(shù)）.However，they involve burning temperatures with a high energy demand and deep carbon footprint，and poisonous chemicals which are harmful to the environment.Alternatives are therefore being sought.
A team of scientists from the University of Coventry are extending one such alternative.They have been using non-poisonous bacteria to oxidize and recover the precious metals-a process known as "bioleaching".They have shown that copper is widely recoverable from e-waste，and that all metals present in EV batteries can be recovered by using microbes（微生物）.If extended，bioleaching facilities would mean that manufacturers of EV batteries and other electronic goods would be able to recover metals locally，relying less on costly exports to recycling centers abroad.
"At present，a key limitation for e-waste recycling is the lack of certification detailing the types and amounts of metals contained in electronic goods.But with an efficient recycling process appearing，manufacturers have the motivation to use more recycled material in their products，which will change the very design of electronics goods.It's about closing the loop of a product's life cycle，" said the leader of the Bioleaching Research Group，Sebastien Farnaud.
Ultimately，bioleaching technology is born out of the idea of creating a truly circular process for the things that we consume.We need to shift from a mindset and economy where we see waste as an end product，to one where there isn't even a start or an end at all.
（1）What do the statistics in Paragraph 1 indicate？
A．People pay no attention to e-waste recycling.
B．The recycling rate of e-waste is comparatively low.
C．E-waste has caused serious environmental problems.
D．The amount of e-waste is sharply increasing every year.
（2）What is the disadvantage of current ways of recycling e-waste？
A．They are not environmentally friendly.
B．They only apply to certain e-waste.
C．They generate metals with a complex process.
D．They cause a sharp rise in local temperatures.
（3）What do we know about the bioleaching technology？
A．It has been applied abroad.
B．It releases no poisonous gas.
C．It recovers metals by microbes.
D．It promotes the local export trade.
（4）The text is most probably a part of.
A．a(chǎn) travel guide
B．a(chǎn) fiction novel
C．a(chǎn) health magazine
D．a(chǎn) scientific journal發(fā)布：2025/1/1 17:30:2組卷：1引用：2難度：0.6 -
2．The history of Azerbaijani cinema dates back to the end of the 19th century，during which，many excellent movies have been filmed，which are still watched and admired by everyone.
These movies were filmed in many beautiful places：from the comfortable and winding streets of the Icharishahar（Old City）—UNESCO World Heritage Site in Baku—to the beautiful fruit gardens and forests of beautiful areas of Azerbaijan.
Here，on these streets，one of the most famous Azerbaijani films，Arshin Mal Alan，directed by Rza Tahmasib，was filmed.
Filmed in 1945 and characterized by its amazing plot，beautiful music，great singing and acting，Arshin Mal Alan quickly became a box office sensation （轟動(dòng)）.
It remains an important cultural touchstone across Eurasia and has been translated into 86 languages and shown in 136 countries.
The film is about pure love，women's rights，and a young couple's dreams for a modern way of life.
The plot tells us about a rich young man named Asker.One day，he decides to get married.However，according to the Eastern rule，a bride （新娘） needs to cover her face before the wedding.But soon he finds a solution to this problem.On the advice of his friend Suleyman，Asker dresses up as a street seller of cloth.By selling goods，these sellers can enter houses where the women and girls choosing their cloth don't cover their faces.Now Asker can go into any yard and choose a bride.
The film has a lot of entertaining moments，songs and humour.The black-and-white version of this film has also been restored and can now be viewed in colour.

3．When we see a person in trouble，the first idea that comes to our mind is to lend a hand.But what if we see an animal in trouble，does the same rule apply？
This question was raised after a group of penguins were saved from an icy gully（峽谷） in Antarctica.It was filmed for the BBC wildlife series Dynasties.The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young.They built a slope（斜坡） so that a few of the penguins could save themselves.
The case has taken the international media by storm.Viewers watching this film sighed in relief. "I'm so glad.I understand not taking action directly，but a helping hand isn't bothering，right？" viewer Kathryn Shaw said on her Facebook.
However，others think human interference（干涉）is unnatural. "You can't have sunshine throughout your life.To have done anything else would only make matters worse." said the show's creator David Attenborough，according to The Times.
In this case，however，Mike Gunton，the executive producer of the series，said that this was a one-off situation. "There were no animals going to suffer by interfering.You weren't touching the animals and it was just felt by doing this…They had the chance not to have to keep slipping down the slope." he told the BBC.
Such cases are familiar to Paul Nicklen，wildlife photographer for National Geographic.He told Metro，"If it's ever a predator（捕食者） situation，no matter how gut wrenching，you stay out of the way.Even when you're watching a male polar bear eat a baby bear."
"There's no rule book in those situations.You can only respond to the facts that are right there in front of you." Will Lawson，the show's director，told Daily Mail.
（1）What has led to a heated media discussion？
A．The rescue of penguins from a gully.
B．People's various remarks on penguins.
C．Some penguins' sufferings in a gully.
D．Ways of filming the series Dynasties.
（2）Who holds a positive attitude towards human interference？
A．David Attenborough.
B．Will Lawson.
C．Paul Nicklen.
D．Kathryn Shaw.
（3）Which of the following best explains the word "gutwrenching" underlined in Paragraph 6？
A．Making one confused.
B．Making one heartbroken.
C．Putting one in danger.
D．Putting one in place.
（4）What can be the best title for the text？
A．Necessity of Lending a Hand to Animals
B．Protect Animals From Dying Out
C．Human Interference on Dangerous Animals
D．Help Animals in Trouble or Not發(fā)布：2025/1/1 17:30:2組卷：2引用：3難度：0.5
