A man named Randy liked to look for big trees and old trees. He made maps to show where these trees were. He did not want to cut them down. He wanted people to take care of them.
Randy was told that there was a very tall tree on Vancouver Island. The tree was said to be 314 feet tall. That would make it the tallest tree in Canada. Randy started to find the tree.
But someone else found it first. It was found by a logger (伐木工). Loggers wanted to cut down Canada’s tallest tree and all the trees around it.
Randy made a path in the forest so people could see the tallest tree. The tree was so big and beautiful that it would bring them enjoyment. More and more people wanted to save that forest. Thanks to these people, that forest is now a park. Canada’s tallest tree is still there.

3 . I finally climbed into bed at 1: 20 in the morning. My friends had helped me celebrate my 31st birthday in the basement apartment, where I lived.
Earlier in the day I had prepared for the unlikely event of a flood. We are about a third of a mile from the banks of the Ahr River. It had been raining buckets that week and the government had sent out a flood warning, though not for where I was. Still, I’d placed sandbags on the floor outside my garden door and put electronics on tables. “Silly bro!” My friends laughed at me for doing that, but I thought, why take a chance?
As I drifted off to sleep, I was awakened by the sound of rushing water, as if I were lying beside a waterfall. When I got off the bed, I was shocked that cold water was rising fast. In darkness, I grabbed my cellphone and turned on the flashlight. When I stepped out of the bedroom, I saw water shooting through the gaps of the door.
I began to panic. I knew I had to get out—fast! In bare feet, I started to make my way to the only escape: the door that led upstairs to the main floor. Finally I made it to the door and tried several times to-pull it open even just a little bit, but the rushing water shut it again. I looked around for anything I could use to keep it open. There in the corner was a coat rack (架子). I took it and, once again, opened the door, throwing the coat rack between the door and the frame (门框) to keep the door from shutting. Finally, I managed to make a gap just wide enough to squeeze (挤) through and make it into the hallway.
I leaped on to the stairs and ran outside. I stood there in the darkness, wet through. What was once a lovely street was now a waterscape, with floating ruins instead of people and cars. The river had drowned (淹没) the neighborhood!

4 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.
In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.
The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.
They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.
So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

6 . While Ellard Hunting and fellow researchers were out studying the weather at a field station in England, they noticed something unexpected on their instruments. Though there was no storm coming, the scientists’ electric field monitors recorded a strange increase in atmospheric electric charge(电荷) .
Nearby, honeybees that lived in on-site hives were swarming (蜂拥) as they tried to find a new home. When the team took a closer look at their data, they discovered that the swarming honeybees had created an atmospheric electric charge. The researchers shared more details about their findings in the journal Science.
“This is the first report of biology as a source of space charge.” says Hunting, a biophysicist at the University of Bristol in England. Scientists had known that individual bees carry a small charge while flying through the air, caused by the friction of their body parts against the air and each other. It’s similar to how rubbing a balloon on a piece of cloth creates static electricity (静电). Scientists believe a bee’s charge helps pollen (花粉) stick to it and signals to other bees which flowers have already been visited. But until now, researchers had never recorded such a high voltage (电压) among swarming honeybees.
In terms of electricity generation, a bees warm’s charge isn’t so impressive:It would take about 50 billion bees to power an LED light. But compared to the charges produced by common weather events, the bees’ charge density was six times greater than an electrified dust storm and eight times greater than a thunderstorm cloud.
Scientists hope to continue exploring how biology influences physics and are curious to know if something similar is happening with other wildlife, such as birds and bats.

8 . Here are some fantastic parks in San Antonio.
Brackenridge Park
The park was first established in 1899 and has been popular with both locals and visitors ever since. Towering trees and peaceful riverbanks will greet guests along the park’s paths, and the facilities include playgrounds, museums, a miniature train, a Japanese tea garden, and one of the oldest golf courses in the city.
Friedrich Wilderness Park
In the park, you’ll find about 10 miles of paved(铺过的)and unpaved trails(路线), with a little something for everyone. From rocky climbs to deep canyons, and enchanting forests to open views, there’s no shortage of natural beauty. The area is nationally famous for birdwatching.
San Antonio Missions National Historical Park
The park is the state’s only one on the list of UNESCO World Heritage Site. It covers quite a large area, so it’s best to make it a full-day or at least a half-day trip so you can be sure to cover everything. While the Alamo is a separate attraction, you will get to enjoy the architectural wonders of Mission Concepcion, Mission San Jose, Mission San Juan, and Mission Espada. They’re all connected by a hike and bike trail, with plenty of stops along the way to picnic, climb trees, and refill water. Admission is free!
Eisenhower Park
Just a 20-to 30-minute drive from the city center, the park puts the best landscapes in the Texas Hill Country on full display, holding 6 miles of hiking trails, both paved and unpaved.

10 . Chimps live in a male-dominated society, where most of their valuable partners are other males. However, as young male chimps become adults, they continue to maintain tight bonds with their mothers, a new study finds.
“The dramatic changes of adolescence are difficult for chimps, just like they are for humans,” says Elizabeth Lonsdorf, an expert on primates (灵长动物) at Franklin&Marshall College who was not involved in the study. “Sure enough,” she adds, “their moms remain a key social partner during this time.”
Previous research has shown chimp mothers provide their sons with support that goes far beyond nursing. Young male chimps that are close with their moms grow bigger and have a greater chance of survival. What’s more, losing their mothers after weaning (断奶), but before age 12,gets in the way of the ability of young chimps to win other males and reproduce.
To see whether this bond extends later into life, researchers followed 29 adolescent (9 to 15 years old) and young adult (16 to 20 years old) male chimps at a research site in Kibale National Park in Uganda and observed them from a distance for 3 years. The team found that the young adult males spent less time with their mothers than the adolescents did—26% vs. 76%. As the male chimps grew older and more independent, they began to travel over wider ranges and spent more time away from their moms.
However, when these young adult males happened to be in the company of their mothers, they acted just like the adolescents. They groomed (梳理) their moms just as often and kept track of them. “Many mothers remained the males’ ‘best friends’ or ‘social partners’ they associated with most frequently,” says study co-leader Rachna Reddy from Harvard University.
Such persistent ties are also common in humans after sons leave their mothers and live on their own—especially in tough times, Reddy says. “We really feel what it’s like to not be able to see our mothers when we want to in tough times. The importance of those bonds in our lives and the comfort we get from them have deep evolutionary roots.”
