Since the Endangered Species Act （ESA） was passed in 1973，it has helped hundreds of species avoid extinction in the United States.The strong conservation policy has been used as a model in other countries.But it's not as successful as it could be，a new study finds.
Researchers have discovered most species are not being protected until their numbers have become so low that their chance of recovery is slim.
"The ESA is an incredibly powerful law for protecting our endangered wildlife.Yet，for decades，the agency primarily responsible for operationalizing the ESA- the US Fish and Wildlife Service （USFWS）一has been starved of resources，" lead author Erich Eberhard says.
"As a result，we are very slow 10 give species the protection that they deserve.We typically wait until species are extremely rare and thus at extreme risk of extinction，and then，when a species is finally listed，the USFWS starts trying to recover it."
In 1993，a study found that few species received protection under the ESA until their populations became very small.For the new study，researchers repeated the methods used in the earlier research to see whether protections have become better since the problem was first noted.They also looked at trends in "wait times"一the amount of time between when a species is identified as potentially needing protection and when it actually receives protection under the ESA.
"Our analysis suggests that，in the nearly 30 years since attention was first brought to this problem，we have not become more active in protecting endangered species，" says Eberhard.
The researchers found that the population sizes of species when they first became protected under the ESA are not statistically different from those in the 1993 study.They also discovered that there are long wait limes between when a species is identified as likely needing protection and when they actually receive them.
I can say that our study paints the current state of the ESA as a bit of cautionary （告誡的tale for the strong conservation policy，" says Eberhard.

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

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）.
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.

（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
