Air pollution is the world's top killer, a new global air quality index revealed last year. According to the World Health Organization(WHO), 4. 2 million people die each year from outdoor air pollution, and 91 percent of the world's population lives in a place that exceeds the WHO's guideline limits. With that in mind, Imperial College London has teamed up with biochemical tech startup Arborea to test out its biosolar leaf technology, while also demonstrating how sustainable solutions can address the vital environmental and social issues of today in real-world conditions.
So, what is a biosolar leaf and how does it work? The secret is algae(海藻). Arborea researchers developed a cultivation(培养)system that allows microscopic plants like microalgae to grow on large solar panel-like structures that can be installed on land, buildings, and anywhere with a roof in a built-up city to improve the surrounding air quality. Inspired by the natural process of photosynthesis(光合作用)，the biosolar panels allow the microorganisms to absorb CO2 from the surrounding area and generate breathable oxygen back out again. And they help produce a nutritious, sustainable plant protein with tiny environmental impact—— Arborea's other focus——at the same time. "When I founded Arborea? my goal was to cope with climate change while addressing the critical issues related to the food system," Arborea founder and CEO Julian Melchiorri said. "This pilot plant will produce sustainable healthy food additives while purifying the air, producing oxygen and removing carbon dioxide from the surrounding environment.”
Melchiorri has already had some success with his astonishing project, the world's first living bionic chandelier(仿生吊灯)，which uses the same technology. The light of the chandelier stimulates photosynthesis of the microorganisms on the leaf-shaped modules, absorbing the CO2 inside and releasing oxygen back into the room. The chandelier currently holds pride of place in London's Victoria and Albert Museum's permanent collection.

For the first time, a generation of children is going through adolescence with smartphones ever-present. Jean Twenge , a professor of psychology at San Diego State University, has a name for these young people born between 1995 and 2012："iGen". She says, “Members of this generation are physically safer than those who came before them. They drink less they learn to drive later. " "But psychologically," she argues, "they far more easily get hurt. It's not an overstatement to describe iGen as being on the edge of the worst mental health crisis in decades.''
Today's teens are just not spending as much time with their friends face-to-face where they can really read each others' emotions and get that social support. And we know from lots of research that spending time with other people in person is one of the best predictors for psychological well-being and one of the best protections against having mental health issues. They're more likely than young people just 5 or 10 years ago to say that they're anxious, and that they have symptoms of depression.
How much of a factor is parenting? “Parenting is playing a role. Many parents are worried about their teens driving, and going out with their friends and drinking. Yet parents are often not worrying about their teens who stay at home on their phones all the time. But they should be worried about that. I think parents are worried about the wrong thing," Professor Twenge remarked.
She proposes several helpful solutions, "The first is just awareness that spending a lot of time on the phone is not harmless and that if you're spending a lot of time on the phone, then it may take away time from activities that might be more beneficial for psychological well being, like spending time with people in person. And then for parents, I think it is a good idea to defer giving your child a smartphone as long as you can.”

A.Generation with high intelligence.
B.Generation in information age.
C.Physically strong generation.
D.Psychologically healthy generation.
2.How can today's teens avoid mental health crisis?
A.By making more friends online.
B.By seeing psychologists frequently.

D.By communicating with friends face to face.
3.What should parents concern according to Professor Twenge?
A.Their teens' chatting with classmates.
B.Their teens' poor school performance.
C.Their teens' addiction to smart phones.

4.Which can best replace the underlined word “defer" in the last paragraph?

A woman from the United Arab Emirates has regained consciousness after spending 27 years in a vegetative state (植物人状态). Munira Abdulla was aged 32 when she suffered a brain injury after the car she was riding in was hit by a bus in 1991. Her son Omar revealed her fantastic recovery in an interview with The National.
He described how the accident occurred when he was four years old and needed to be brought home from kindergarten. Ms Abdulla's brother-in-law drove her to school to collect Omar and the family were driving home, with mother and child in the back seat, when they were hit by the bus. As the bus hit, Ms Abdulla threw herself around her son to protect him from the impact. While she suffered a severe head injury, he escaped with just a bruise. Omar described how his mother was left untreated for hours because the family were unable to call for help and there was little traffic, before she was transferred to a clinic in London.
There, doctors diagnosed a vegetative state, meaning she was completely unresponsive but able to feel pain. She was transferred back to the UAE and put on a breathing machine and a feeding tube to keep her alive, spending the next few decades hooked up to machines. But in April 2017, Sheikh Mohamed bin Zayed, the Crown Prince of Abu Dhabi, heard of her case and gave her family a fund for treatment. Ms Abdula was flown to Germany where she underwent surgeries to repair her muscles while being given medication to improve her sleep patterns.
Around a year later she began making strange sounds, and within three days she called out to Omar using his name, "It was her! She was calling my name, I was flying with joy；for years I have dreamed of this moment, and my name was the first word she said," he said.
1.How old was Ms Abdulla when she came to life?
A.27. B.28
C.32. D.59.

A.People there lacked skills of first aid.
B.Omar’s uncle suffered a slight injury.
C.The traffic accident happened at a quiet place.
D.Ms Abdulla forgot the emergency phone number.
3.Why was Ms Abdulla sent to Germany?
A.To receive free treatment.
B.To recognize her son's voice.
C.To meet Sheikh Mohamed bin Zayed.
D.To have operations and improve her condition.
4.What's the text mainly about？

A Special Appointment
Years ago I moved to Woodland Hills to take a job in a small hospital’s emergency department. No one wanted to work on Christmas Eve, so the shift（轮班）went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.
At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.
The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don’t remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.
The following year a new doctor had joined the group, but I wanted to see if Mr. And Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild.
Mr. Lee, his family and I spent 13 Christmas Eves together. In the later years the staff all knew about the story and would work to give me time with him in the break room, where we spent a half-hour each Christmas Eve.
