Scientists near San Francisco work to identify a type of endangered fish using a tool that was originally made for treating cancer.
Currently，CRISPR is used to change the genetic material in specific cells.By changing the structure of immune cells，it helps recognize and fight cancer.The same technology is now used in a special machine called Sherlock，which，of course，is named after the famous investigator Sherlock Holmes.They do not，however，use Sherlock to change fish cells.Instead，the ocean researchers catch the fish，collect a small amount of mucus（黏液） and then test the cells to find the genetic makeup of the fish.It can be done in about 30 minutes.
In the past，the researchers would have to wait weeks or months to get test results.
The researchers have found that the technology is extremely helpful when looking at different species of Chinook salmons（奇努克鮭），because they look nearly the same.However，some of them are endangered，and the scientists need to keep track of them.
In the past，the scientists would catch the Chinook salmon and measure them to tell them apart. "It's not very accurate，" said Andrea Schreier，an associate professor at the University of California in Davis.Now she is working on the salmon.Schreier said when they catch the fish，the Sherlock machine can quickly tell them if they have one of the special sal mons.It's important because it allows the scientists to do things that will help the endangered salmon live longer.For example，they can catch them in lakes far away from the coast and take them by truck to the San Francisco Bay，In the past，the fish might have tried to make it to the Bay by swimming in rivers.However，due to climate change，the river water is sometimes too warm for the fish to make the trip safely.
Schreier said she feels good about the project because she likes being able to assist with conservation. "I really want to work to maintain our ecosystems and our native populations，given the pressures humans place on them through our different activities."

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）and hydrometallurgy（濕法冶金術）.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．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 -
3．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.
