1 . David Willard has been checking the grounds of Chicago’s lakefront exhibition center for dead birds for 40 years. One morning this year he found something horrible; Hundreds of dead songbirds, so thick they looked like a carpet. Nearly 1,000 songbirds died during the night after crashing into the center’s windows. According to bird experts, the result was caused by a combination of migration conditions, rain, and the exhibition hall's low lights and walls with windows.

Birds don’t see clear glass and don’t understand it’s a deadly barrier. When they see plants or bushes through windows, they head for them, killing themselves in the process. Birds that migrate at night, like sparrows, rely on the stars to navigate. Bright lights from buildings both attract and confuse them, leading to window strikes or birds flying around the lights until they die from tiredness—a phenomenon known as deadly light attraction.

But even in the best of circumstances, spring and fall are dangerous times for migrating birds. When they migrate over major cities, the risks increase. Hundreds or thousands of dead birds may appear on city streets after a wave of migrants has passed through. In all, about 100 million to 1 billion birds die each year in North America from crashing buildings.

The good news is that people can greatly reduce the danger with some simple methods. Window strikes are easily preventable, said Anna Pidgeon, an expert at the University of Wisconsin-Madison. Architects can design windows with markings in the glass that birds can easily recognize, she said. People can paint their windows as well.

2 . Have you ever wondered what happens to your mobile phones and laptops after you throw them out to make way for a newer model? According to its latest Global E-Waste Monitor, India is the third top producer of e-waste in the world. E-waste in Indian landfill goes on to pollute soil and groundwater, affecting food supply systems and water sources.

Thankfully, the country has a new group of artists who are changing these thrown mechanical items-from mobile phones to old televisions- into large murals (壁画) and artworks to creatively show their concern for the waste problem.

Over the past quarter of a century, Mumbai’s Haribaabu Naatesan has transformed hundreds of tonnes of e-waste into art, integrating elements from nature and industry. “I get my waste material from friends, relatives and neighbours who know my interest in e-art and send me bags of thrown electronic appliances,” says Naatesan. Over his career, he has created huge murals for several companies. He has also showed his work at the India Art Fair, as well as several other national displays.

Another artist Vishwanath Davangere has also long worked with e-waste. He likes to take apart old laptops and reassemble (重新组装) them into birds, animals and plants. After retirement, he started pursuing this hobby more seriously and started selling his creations across the world. His most outstanding works include a robotic Egyptian statue with glowing red eyes and a Milky Way made from keyboard keys. He hopes to enable others to reconsider their own consumption habits and make more environmentally conscious choices.

“By giving e-waste a second chance, I aim to raise awareness about the environmental impact of electronic waste.” says Davangare, who today has a collection of more than 600 eco-art objects.

6 . My name is Ben. I am 13, and I live in Chantilly, VA. Just yesterday, June 24, I was at home watching my sister, who is mentally handicapped (弱智的). My father was at work while my mother and younger sister were at my mother’s office.

I had noticed the clouds growing darker and the ones to the east were turning green. At first I thought nothing of it, but then on TV, the weather reporter was announcing a big thunderstorm warning, one that usually brings hail (冰雹) and heavy rain.

After seeing that, I called my mother and told her about it. She told me I should not be worried because it was just a thunderstorm so we hung up. Then I looked outside and noticed it was almost pitch black at 4：30. I took a flashlight (手电筒) because I was sure the power was going to go out any second.   Then no sooner had I gotten back from getting the flashlight than the weather reporter announced a Tornado Warning! I had never been in an actual tornado before, but I had seen some funnel clouds before in Montana.

Suddenly I realised I had no time to lose and I had to try to get my sister down the stairs to the basement in a matter of minutes. I surprisingly got her down there with no trouble at all and I raced back up the stairs to get the cordless phone. When I got back downstairs my dad called and told me to get downstairs immediately. I told him I was already down there! He said OK and we talked for a few seconds and then we hung up. Then_through the basement windows, the only thing_I_could_see_was_lightning.

I do not recall hearing of any deaths, or too many injuries so I guess everyone got a good head start to run to their basements. Either that or we are all lucky.

7 . The earth is struck daily by 60 tons of rocks from outer space. However, finding these ancient rocks is no easy task. Most meteorites (陨石) fall directly into water. And those that hit land can be difficult to spot among other rocks.

Fortunately for researchers there is one place on Earth where meteorites find it difficult to hide: Antarctica. “There are probably fewer meteorites falling per acre of land in Antarctica than in other parts of the world,” said Ralph Harvey, a professor at Case Western Reserve University. “But if you want to find things that fell from the sky, lay out a big white sheet. And Antarctica is a 5,000-kilometer-wide sheet.”

Finding meteorites in Antarctica is so relatively “easy” compared to the rest of the world that an estimated two-thirds (around 45,000) of those ever discovered have come from the icy continent. The challenge, however, comes not only from the terrible conditions, but also from knowing where to look to make any expedition worthwhile.

In an effort to greatly improve the collection rate of Antarctic meteorites, a Belgian—Dutch team of scientists has unveiled (展示) what they’re calling a “treasure map” for the region. “We expect the treasure map to be 80% accurate,” said Veronica Tollenaar, who led the study.

After landing in the snow in Antarctica, a meteorite will either be directed into the ocean or brought back to the surface of what’s known as a “blue ice” area. As meteorites come out in these special “blue ice” areas, their color contrasts (对比) against the deep blue ice, making them easy to spot. The treasure map marks more than 600 special “blue ice” areas. They estimate that these sites may contain anywhere from 340,000 to 900,000 surface meteorites.

The researchers add that these locations also likely contain rare meteorites, such as angrites, brachinites or even Martian meteorites.

“Collecting these ancient rocks will further improve the understanding of our Solar System,” they write.

8 . Suzanne Simard, a professor of forest ecology who called herself a “forest detective”, was raised in mountains in Canada. Few scientists make much impact with their PhD thesis, but, in 1997, she did just that. Her research on the “wood wide web” made the cover of Nature and transformed our understanding of forests. What was then a challenge to traditional ideas is today widely accepted.

A mushroom is the part of a fungus (真菌) that sticks up above the ground. Thin, white threads grow from its stem deep into the soil. These threads are called hyphae (菌丝). Hyphae connect themselves to tree roots. They also stretch from root system to root system, like an underground network. This network may go for miles. Hyphae pick up nutrients and water from soil. The fungus threads that connect to tree roots share their nutrients and water with the trees. In return, they sip a bit of the sugar the trees make. Sharing helps both trees and mushrooms live. It’s also how trees communicate.

When a tree is being eaten by bugs, it makes chemicals to shoo them away, sort of like bug repellent (驱虫剂). The chemicals travel through the tree, down its roots, and into the hyphae network. Other trees connected to the network taste the chemicals. That tells them a nearby tree is under attack, so they start to make their own bug repellent. Trees do more than share warnings through the hyphae. They also help each other. In the fall, paper birch trees drop their leaves and can no longer make sugar. So, a fir tree that stays green all winter uses the network to send extra sugar to the birch until spring comes again. This system of sharing information and nutrients through the hyphae is sometimes called the “wood wide web”, because it works a bit like the Internet.

Local climate sets the stage for the wood wide web, researchers say. In cool temperature and boreal forests, where wood and organic matter decay slowly, network-building EM fungi rule. By contrast, in the warmer tropics where wood and organic matter decay quickly, AM fungi dominate. These fungi form smaller webs and do less intertree swapping, meaning the tropical wood wide web is likely more localized.

Ecologist Thomas Crowther’s results suggest that as the planet warms, about 10% of EM-associated trees could be replaced by AM-associated trees. Microbes in forests dominated by AM fungi deal with carbon-containing organic matter faster, so they could liberate lots of heat-trapping carbon dioxide quickly, potentially accelerating a climate change process that is already happening at a frightening pace.

9 . Johannes Fritz, an Austrian biologist, needed to come up with a plan again if he was going to prevent his rare and beloved birds from going extinct.

To survive the European winter, the northern bald ibis needs to migrate south for the winter over the Alps. But shifting climate patterns have delayed when the birds begin to migrate and they are now reaching the mountains too late to make it over the peaks, locking them in an icy death trap. Determined to save them, he decided to teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. He was confident that he could succeed in this daring, unconventional plan.

Some 400 years ago, the Europeans hunted these birds without stopping and devoured the last in the wild, causing the birds to disappear entirely from the wild. When Mr. Fritz was born 56 years ago, the northern bald ibis could be found in Europe only in captivity (圈养).

Mr.Fritz has spent his career reintroducing the birds into the wild. Through years of trial and error, he learned to fly like a bird. He modified (改装) a lightweight aircraft so it would fly at speeds slow enough for the birds to keep up. In 2004, he led the first flock from Austria to Italy, and has since led more migrations. But the route he originally taught the ibises does not work successfully. With climate change warming the area where the birds summer, they now start their migration at the end of October instead of the end of September. The trip is expected to take about six weeks, “Still, we’re optimistic that it’ll work,” said Mr. Fritz.

His family and colleagues witnessed the risks he was taking. “But the unavoidable risks are necessary,” Mr. Fritz said. “It’s not so much a job, but my life’s purpose.”

2. What does the underlined word “devoured” in paragraph 3 mean?

A．Destroyed.

B．Abused.

C．Released.

D．Raised.

3. Why was Mr. Fritz’s initial route for the birds ineffective?

A．Owing to the long time it consumes.

B．For the slow speed of his modified aircraft.

C．Because of the toughness along the first route.

D．Due to higher temperatures in the summer habitat.

4. Which of the following can best describe Mr. Fritz?

A．Honest.

B．Innovative.

C．Straightforward.

D．Demanding.

10 . People flood into cities for understandable reasons: more job opportunities, more cultural diversity and larger communities. Yet living in a concrete-walled, green-poor, urban environment takes away from our-very essence our fundamental need to be close to nature. We can’t quite break the link with our evolutionary (进化的) past and part ways with our origins. Surrounding ourselves with walls and ‘screens, we tend to pay a price, often with our health and quality of life.

In Japan, a populous country with vast expanses of green forests, an ancient tradition, known as shinrin-yoku, or forest bathing, tries to balance out the pressure from urban living. It’s the practice of spending prolonged periods of time with trees to gain from their many health benefits. In a book hitting shelves this month, Forest Bathing: How Trees Can Help You Find Health and Happiness, Dr. Qing Li, the world’s foremost expert in forest medicine, introduces readers to the valuable practice of forest bathing. The book features more than 100 color photographs of forests around the world. One may reject this kind of book as yet less convincing, but the point is that Li has not just practiced forest bathing, but has also studied its impact on people’s health through numerous scientific studies. He has data to support his claims, collected in a long list of expert-reviewed articles at the end of the book.

The book lists studies that consistently show-a substantial, reduction of stress hormones (应激激素). Essential tree oils found in forest air increase energy levels by more than 30 percent and improve a general state of well-being, including improvement in sleep.

Scientific results apart, the, concept of forest bathing shouldn’t be so surprising. Who hasn’t felt an inner sense of well-being when walking along a quiet forest path? Stepping into a forest, away from the artificial sounds and smells of urban life, does feel like pushing a life reset button, reestablishing a connection with our deepest needs.

To celebrate this wonderful book and. what seems to be a rediscovery of forest bathing in our life, I’m going to go now—to take: my forest bath.
