As part of his role in the Air Force Volunteer Reserve, John Lewis often visited military schools. But it was at a London school in 2014 that an accident happened. He had 11 operations in total and it was two years before he could walk again.
Although John improved physically, he couldn’t recover from what had happened. John was diagnosed with post -traumatic (创伤后) stress disorder (PTSD), but none of the treatment seemed to help. Then last year, at a hospital, a doctor told him a puppy (小狗) could manage stress and might help with his anxiety.
In May 2019, they adopted a black puppy called Gibson. He says, “I'd never thought of it as a comfort. After just a few weeks, I could feel myself improving. If I was feeling anxious, he would jump up on the sofa and sit on my chest and I found that really relaxing and comforting. Wherever I go, he will follow me and it’s really helpful to my anxiety. We go out and play Frisbee (飞盘) and I now look forward to going out for walks while I would always make excuses to stay in the house before.”
His wife Anna has also noticed a difference. She says, “Gibson is an incredible dog that adores John. He is a fantastic companion. It has given him a focus and a lease on life.”
John is now. taking part in Generation Pup, a groundbreaking study that tracks puppies through adulthood to learn how their early experiences and environment affect their development. John says, “I really enjoy tracking this through the study, watching his personality begin to grow and support me on my road back to mental health, which he is playing a big part in.” “Gibson has done so much for me in a short space of time. I want to do something for him.”
1.What can we learn about John Lewis after the accident?

C.How to get on with a puppy. D.How Gibson comforted him.
3.What does the underlined part “a lease on life” in paragraph 4 mean?
A.More wisdom. B.Better life.
C.Great wealth. D.Lifelong ambition.

Ecology is a complicated thing. c Given the facts that elephant damage often kills trees and bush fires often kill trees, a combination of the two will make things worse. However, as research shows just published in Biotropica, by Benjamin Wigley of Nelson Mandela University, if a tree has already been damaged, fire can actually help to make things better.
Since 1954，the Kruger National Park has been the site of experiments. Dr Wigley carried out these experiments by looking at trees in three different zones. In one of these zones, the vegetation (植被) was burned every year. In the second it was burned every other year. The third zone, by contrast, was actively protected from fire. To keep things consistent, he only looked at the fate of a single tree species, the marula (玛鲁拉树), whose bark is often eaten by elephants. In July 2016, he and his colleagues identified 20 marulas in every zone and used a hammer and a knife to remove a 5 cm circular section of bark from each of them.
To their surprise, damaged trees in the annual burnt zone regrew 98% of their lost bark during the two years of the study. Those living in the second burnt zone regrew 92% of it. But those in the zone where fires were banned regrew only 72%.
The researchers also found something else around the trees' wounds: ants. Ten of the 20 trees in the fire-banned zone developed ant colonies in their wounds. The ants were known to damage tissue healing. By contrast, only five trees in the second zone and three in the annual zone developed ants' nests in their wounds.
It looks, therefore, as if bush fires are burning trees'。wounds to kill the ants. Though such fires are surely harmful to healthy trees, it seems, in an example of two negatives making a positive, as if they are actually helpful to sick ones.
1.What is the finding of the research?
A.More fire does good to trees. B.Fire makes damaged trees. grow better.
C.Ants always help trees gr8w well. D.Elephants often damage tree barks.
2.What do we know about the experiments?
A.They were finished in one year.
B.They were carried out in different parks.
C.The damaged trees grew well as other trees.
D.The trees chosen had been damaged by the researchers.
3.Why did the author mention ants in the last two paragraphs?
A.To prove that ants are bad animals.
B.To show the benefit fire brings to damaged trees.
C.To express how ants influence trees' growth.
D.To introduce the role ants play in ecology.
4.What is the best title for the text?
A.Is Fire Totally Bad for Trees2 B.How does Fire Destroy the Trees?
C.The Balance of Trees and Ants D.Trees, Animals and Disasters

While studying at Jadavpur University, Banerjee wanted to find a creative and socially beneficial alternative to bricks. Along with his classmates, Banerjee created, a social enterprise called Qube in 2017. Its product is the Plastiqube-an alternative brick made from waste plastic.
Banerjee and his team work with waste collectors to gather garbage, including water bottles and abandoned bags. The garbage is then cleaned, cut up and pressed into blocks by hand. “Each Plastiqube brick costs 5 to 6 rupees （about 8 cents） to make，while the average clay brick sells for about 10 rupees (14 cents),” Banerjee says. What 's more, unlike traditional bricks, Plastiqubes don' t use any mortar (砂浆). “They are basically like Lego bricks,” explains Banerjee, now aged 22. He adds，“There are interlocking designs on the bottom and the top, and they lock between each other.
India is estimated to throw away over 25, 000 tons of plastic waste every day. Around 40% of it is left uncollected. “We’re building something sustainable (可持续的) out of garbage,” Banerjee says. By taking coal and mortar out of the brick making process, Banerjee claims Plastiqubes can reduce energy use by 70 percent, generating a much lower carbon foot-print than traditional bricks.
Each Plastiqube brick contains 1.6 kilograms of waste plastic. They haven't yet been tried out for practical purpose but tests on their fire resistance and long- term steadiness are now in progress. Banerjee believes they will last even longer than traditional clay bricks, while removing waste plastic from the environment for centuries.
Banerjee's innovation has, already won him recognition. He was a regional finalist for the United Nation's 2018 Young Champions of the Earth awards. He is also part of the Yunus and Yunus Global Fellowship. Banerjee will not only encourage young engineers to dream big, but also to think carefully about the environmental impact. “My advice is to start something while keeping a goal that it has to be sustainable in the long term,” he says.
1.Why did Banerjee invent Plastiqube ?
A.To reduce the cost of bricks. B.To protect the environment.
C.To control the usage of mortar. D.To raise his company 's reputation.
2.Which of the following makes the new bricks join together?
A.Mortar. B.Lego bricks.
C.Average clay. D.Interlocking design.
3.How does the text describe the characters of Plastiqube?
A.By explaining the process. B.By analyzing some cases.
C.By listing some data. D.By giving examples.
4.What can we learn from the text?
A.Banerjee has won lots of national awards.
B.Producing Plastiqube needs little labor force.
C.Plastiqube hasn't been used to build houses.
D.Banerjee likes inspiring teenagers to go for dreams.
