   I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

    I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.

    I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.

    The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

    Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

    A nervous night to be sure,but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH！The parents had done their duty and would probably continue to do so.

    As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input (输入) Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital, said, "Chinese characters enjoy both practical and aesthetic（审美的）value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    Researchers at the University of Chicago have trained an artificial intelligence system, to write fake reviews on Yelp, a website showing customers reviews on shopping or something else, and it's pretty hard to tell them apart from a human review.

    Their study, which will be presented at the ACM Conference on Computer and Communications Security in October, aimed to throw attention onto how easily these systems can write reviews like humans and how damaging they can become if they're not monitored properly.

    Since many small businesses rely on online reviews to help grow and keep their reputation, a future where someone—like a rival or angry customer—could crazily fill their page with negative reviews written by a machine is pretty worrying.

    And, according to the research team, the threat goes far beyond a bunch of fake reviews on Yelp. "In general the threat is bigger," Ben Y. Zhao, one of the authors of the study, said. "I think the threat towards society is large and it really misleads users and shakes our belief in what is real and what is not. I think that's going to be even unimaginable."

    To test how believable these reviews came across, the researchers invited 40 volunteers and had AI generate five fake reviews for 40 actual restaurants. The volunteers were asked how useful they thought the review was and whether or not they thought it was fake. The AI reviews ranked as "effectively indistinguishable" from real reviews，according to the study. Further, the fake reviews were given a 3.15 "usefulness" rating, compared to a 3.28 rating for human reviews.

Sharks have been swimming in the ocean for millions of years. They were on Earth even before dinosaurs! At the top of the world's ocean's food chain, sharks help keep the population of other ocean animals in balance. A large drop in the number of sharks can cause serious problems for all ocean animals. Saving sharks makes sense!

Many people are afraid of sharks. But most sharks are harmless. Only a small percentage of sharks are known to attack humans. It adapt (适应) well to new habitats and eat whatever is available. However, today, sharks are in trouble. Nearly one－third of the 400 shark species are in danger of extinction, largely due to over－fishing. Each year, tens of millions of sharks are caught and killed just for their fins. The fins are used to make shark fin soup.

Humane Society International (HSI) joined with the Jane Goodall Institute's Roots and Shoots program and Beijing Zoo to protect sharks. An exhibit at the zoo, "the Price Behind the Taste—Protect Sharks. Don't Eat Shark Fins", was designed to tell people that shark finning is cruel and unnecessary. It's hoped that the activity will help put an end to the practice.

Shark fin soup is also eaten in the United States. In fact, the numbers of some shark species in US waters have dropped 90 percent in the last 30 years. To slow the fall, laws against the sale of shark fins have been passed in several states, including Hawaii, Oregon, Washington, and California.

When we hold our breath and go underwater, we'll soon be unable to stand it. {#blank#}1{#/blank#} However, there's little chance of catching up with the Sama-Bajau, who can stay underwater with a single breath for quite a long time. 

Sama-Bajau is a collective term（集合术语）that refers to several closely related native peoples. The Bajau live on long houseboats or small wooden houses that are built on the sea, close to the shore in Southeast Asia. {#blank#}2{#/blank#}

 As they make their living primarily from fishing, they have become exper t free divers（自由潜水者）. Bajau divers have the longest daily diving time without breathing among allhumans. {#blank#}3{#/blank#} In their free time, the kids help around the house or play on the beach. 

It appears that centuries of free diving have scientifically distinguished the Sama-Bajau. According to research, the Bajau's spleens（脾脏）are much larger than the average people's on land. {#blank#}4{#/blank#} Besides, the Bajau have also developed excellent underwater vision. 

{#blank#}5{#/blank#} The main cause is massive fishing, which has made it increasingly difficult for the Bajau to make a living and rely on fishing alone. As a consequence, more and more people are leaving the seas, and apparently, it's only a matter of time before the Bajau and their amazing qualities disappear. 

A. Larger spleens can have some weaknesses. 

B. Therefore, many older divers are hard of hearing. 

C. The difference makes the Bajau quite able to dive underwater. 

D. They only go ashore to trade or seek shelter during sea storms. 

E. Bajau children master swimming and diving skills at an early age. 

F. The existence of this special group of people is threatened nowadays. 

G. With free diving training, we can increase the time underwater by a few minutes. 

It's Wednesday at Lismore South Public School, in northern New South Wales, Australia. A group of eight-year-olds practice1 with four-legged friend Maggie. Sandy-haired Charlie says he likes her "because she's so calm."

Maggie, too, is eight human-years old and2 enjoys Story Dogs, which is now in 239 Australian schools. Owner, Anne Meagher, says Maggie was rather 3 good at escaping when she first adopted her. Now Maggie can stay still and patiently allows readers to 4 hbooks on her stomach.
    "It's a simple enough idea, reading to a dog, but somehow the children5 and find reading easier," Anne says. "Maggie6 listens to the children read. She doesn't 7 them or correct them. She's non-judgmental. But the facts show she helps children 8 the process. I haven't had one student in two years who hasn't improved. I think we create a space where they can feel 9 to make mistakes and have a 10 .
    "Story Dogs is, 11 ," says Janine Sigley who, with Leah Sheldon, came up with the program, to make reading12 for children, so they become confident lifelong readers.
    "Schools have reported not only improved reading but also 13 self-confidence among readers who become more prepared to join in classroom activities," Janine says. "Story Dogs is helping to build up kids' interest in reading, and once a child14 to read, they can have a better 15 at school."
