Since the 1920s,the sci-fi(科幻小說(shuō))writers have promised us that a self-driving car can go fast and take us to work while we read the news.But this vision has proved to be more challenging to perform in practice than in theory.
The so-called advanced driver assistance system has been equipped in some electric cars.But it is not what would be considered self-driving.The present automatic pilot tool can help you stay in your lane on the highway.However,according to a driving standards organization,it's just graded to be Level 2 on the five-stage system of automation.Level 5 would be a full self-driving experience with hands off the steering wheel(方向盤(pán)).We aren't there yet.
But that's in the United States.Look farther and the future is closer. "If you look at China,the big cities like Shanghai and Shenzhen are testing self-driving cars in passengers transportation," says George Simpson,director of the Center for Automotive Research in Duisburg,Germany.The self-driving taxis,which are run by Chinese auto and tech giants,are part of a countrywide plan to increase the sales of Level 4 vehicles to about 20 percent by 2030.They allow drivers to switch off mentally while still requiring them to keep their hands on or near the wheel.
What works in China might not work elsewhere,because of differing attitudes towards how data should be used,admits Simpson.Chinese citizens might accept that the journeys of their vehicles are tracked and analyzed to improve traffic flows.But Americans are concerned about their privacy,so they are unwilling to agree with that tracking.
Privacy concerns may delay the promise in the sci-fi that frees you from driving on your way home or to work.Self driving cars must constantly generate data from their sensors and software to make driving decisions,or they would crash.

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

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)).

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.
