Highest Mountains in the World
Mount Kilimanjaro
Mount Kilimanjaro, a dormant (休眠的) volcano, is the highest mountain in Africa. Its summit is 5,895 meters above sea level. Located in Tanzania, it is the largest free-standing mountain rise in the world, meaning it is not part of a mountain range. Kilimanjaro is made up of three volcanoes: Kibo, Mawenzi, and Shira. Kibo is the summit of the mountain and the tallest of the three volcanic formations. While Mawenzi and Shira are extinct, Kibo is dormant and could possibly erupt again.
Mount Everest
Mount Everest is the highest mountain in Asia and the highest mountain in the world. Its summit is 8,848.86 meters above sea level. It is located in the Himalaya Mountain Range on the border of Nepal and China. The Chinese name is Chomolungma, which means "Mother Goddess of the World". The Nepali name is Sagarmatha, which has various meanings.
Denali
Denali is the highest mountain in North America. Its summit is 6,193 meters above sea level. It is located in the USA, in the state of Alaska. "Denali" comes from Koyukon, a traditional native Alaskan language, and means "the tall one". This name had been used for many generations and was used by early non-native researchers and naturalists. But in 1896, William A. Dickey, a prospector (探矿者), began calling Denali "Mount McKinley", in honor of William McKinley, a presidential candidate at the time.
Mount Vinson
Mount Vinson is the highest mountain on Antarctica. Its summit is 5,140 meters above sea level. It is located in the summit plateau of Vinson Massif, near the base of the Palmer Peninsula in western Antarctica. Mount Vinson is part of the Sentinel Range of the Ellsworth Mountains. It was spotted from the air by U.S. pilot Lincoln Ellsworth in 1935.
As a senior school graduate, during COVID-19 outbreak, I've had many concerns, the greatest one of which was being unable to help my community, except for wearing my mask, following the health officials' guidelines, and assisting seniors to get their groceries.
Then it struck me. Solving COVID-19 relied only on individual steps and the goodwill of human consciousness. But the next challenge we have to deal with ahead is climate change, known as the silent pandemic without a vaccine (疫苗). So, all I could think of was: Why don't we do the same, and deal with it through our everyday activities?
I've created an App, EnRoute, to help reduce carbon emissions (排放) from shopping and transport activities. Even though I've never coded (编码) before, my will was greater than any excuse I could think of. The first version was just a one-screen App. Through the quarantines (隔离), I've had only 70 people to test the concept with and created little impact. Plus, leading a social organization seemed like a small boat in a rough sea to me. But instead of giving up, I chose to fill the gap.
And the coolest thing is that the more I was learning, the more people got interested in the idea. Through every leadership program, I built a stronger EnRoute Community where each person was equally passionate and brave to make a change. Their enthusiasm was my greatest fuel. At least I traveled across the world without a single carbon emission.
Fast forward to today, through EnRoute, over 4,000 people reduced more than 150,000 kg carbon emissions. The App turned into an international movement. And I even had the pleasure to be the first-ever Macedonian Global Teen Leader+Princess Diana Award Winner.
It turns out that except for being a good time to reflect and relax, bridge years can be a powerful tool to change the world as well!
Octopuses (章鱼) in the wild have often been observed changing their skin color to catch their food or avoid being caught. Now, for the first time, a researcher has shot an attractive video of an octopus called Heidi rapidly changing into a quantity of colors while dreaming.
The video, part of Octopus: Making Contact, a documentary first shown on PBS on
October 2, 2019, was shot by a fish lover David Scheel, who has raised Heidi in a fish tank since she was young. The professor at Alaska Pacific University in Anchorage believes that the octopus — whose skin went from pale gray to ghostly white to deep, dark violet, before changing into a greenish-brown camouflage (伪装) pattern — was dreaming of catching her next meal.
" She's asleep; she sees a crab (螃蟹), and her color starts to change a little bit, " Scheel says in the video. " Then she turns all dark. Octopuses will do that when they leave the bottom. " He adds. " This is a camouflage like she's just caught a crab, and now she's going to sit there and eat it, and she doesn't want anyone to notice her. If she's dreaming, that's the dream. " Scheel's theory about Heidi's pleasant dream originates from the fact that animals with the ability to camouflage have never been observed changing colors so abruptly while sleeping.
The hour-long documentary, which tracks Scheel's developing relationship with the octopus, also shows Heidi's other skills. She enjoys playing with small toys, watching television — particularly The Big Bang Theory — and solving puzzles. The talented octopus can also escape from small spaces, use tools, and even press a button on a remote control. Like any smart family pet, Heidi recognizes Scheel and his teenage daughter Laura and excitedly rushes to her tank's side in greeting every time either comes close.
Buying furniture is easier than ever. You can even order a new table and chairs online without ever leaving home. But did you ever think about how furniture is made? The process begins with trees but now researchers have found a better way: growing it in a lab instead of a forest. Instead of cutting down trees and adding to deforestation (砍伐森林), Velásquez-García said, " If you want a table, then you should just grow a table. "
The research group found a way to actually grow plant tissue (组织) — wood and fiber — in a lab that is similar to the way cultured meat is grown. While there is still a long way to actually grow a table, the team was able to grow structures from cells from zinnia leaves.
Making furniture and other items from biomaterials could eliminate cutting down trees in forests. " The way we get these materials hasn't changed in centuries and is very inefficient, " said Velásquez-García. " This is a real chance to avoid all that inefficiency. "
There are other benefits to using lab wood too. Lab grown wood can be handled to take on any shape — like 3D printing — so it may be possible to build a table without glue or screwing parts together.
Beckwith, a mechanical engineering PhD student, was inspired by a visit to a farm to try to make land-use more efficient and environmentally sound. " That got me thinking: Can we be more strategic about what we're getting out of our process? Can we get more outputs for our inputs? " she told MIT News. " I wanted to find a more efficient way to use land and resources so that we could let more farmlands remain wild, or to remain lower production but allow for greater biodiversity. "
Today, the two largest uses of trees are to make wood products and paper. When new biomaterials become readily available, forests will lose their economic value and will be preserved for their environmental, health, and recreational value. These researchers, like Velásquez-García, are speaking for the trees.
Unusual weather this summer has hurt many gardens in the United States. For many, the problem is too much rain. Do you still want to grow tomatoes, roses in that sunny place? It can be done. We will look at three ways you can use to correct the problem of too much water.
One way is to drain (排水) the water away to some lower location. The simplest way is with a ditch (沟), or, if your garden is large, a few ditches. Ditches crossing your garden need not be unpleasant to look at or troublesome. Picture a garden in which flat stones line ditches and form bridges across ditches that cross paths. These waterways may look like a classic Persian garden.
Dig a ditch, as described above, then lay in black pipe that is about 10 centimeters across its width. Available at home and building stores, the pipe is made to bend easily, and the holes in it let in water. Cover the pipe with a piece of cloth that water can pass through to keep out dirt and a layer of small stones.
A third way to give your plants more air is to raise them above the water. Trees and bushes can be planted on raised piles of soil, often called " beds " . The beds need to be wide enough to allow roots to spread. If you want a bigger plant, give its roots more room to grow. To make a raised bed, build a box at least 15 centimeters high of wood or stone.
A. Then place the soil.
B. You have a variety of plants to choose from.
C. Do you want to keep your garden where it is?
D. Do you know how to shelter your garden in the sun?
E. The whole system can be a beautiful water " feature " .
F. How wide depends on the eventual size of the plant.
G. Another way is to bury pipes with small holes underground.
The epilepsy (癫痫) changed Parker's life completely. The Fresno boy was having seizures (突然发作) almost 1 . He no longer could attend public school, and his time with friends was 2 . Then, Parker met " Toby the Great " .
Toby, the yellow dog didn't look 3 enough at first. Labrador Retriever Rescue of Fresno had brought him from a local 4 . Parker's mother, Mandy, recalls a thin, hyper (亢奋的), dirty dog. She was 5 this was not to be their dog. But Parker 6 Toby. And so Toby joined the family.
Shortly Toby taught himself how to 7 his boy's seizures before they happened. It slightly 8 Mandy the first time Toby tried to help. He was jumping on Parker, and biting lightly his mother's hands. Mandy called a 9 for advice, worried about this strange, irregular 10 . Then Parker had a seizure. It turned out Toby was trying not to let Parker get up because he could 11 a seizure coming and was trying to 12 Mandy.
Since then, Toby has learned how to fetch emergency seizure 13 for Parker. He'll also run to get Parker's mom when a seizure is 14 . If Parker is sitting down when a seizure is about to happen, Toby 15 on the boy and doesn't let him 16 .
Parker says Toby helps him feel safe and 17 . Along with being a friend, the dog has given him the 18 to be more independent.
" I could 19 sleep in my room alone, just me and Toby, " Parker said. " I can go out and ride my bike, just me and Toby. Toby's 20 changed, too. He went from being a homeless dog, to rescue, to the most important part of my medical team. "
" Our family rescued Toby, " Parker says, " but he really rescued me. "
In the 1940s, China (report) 30 million cases of malaria (疟疾) each year. In the 1950s, Chinese health authorities began introducing measures to treat and prevent the disease. Now, after a 70-year campaign and more than four years of zero new cases, China is officially malaria free, (recognize) by the World Health Organization (WHO).
The WHO gives malaria-free certificates (证明) to countries when they have presented that they've stopped nationwide spread at least three continuous years. Countries also need to have monitoring and reacting systems in place can prevent indigenous cases of the disease from coming back — indigenous in this case meaning infected (感染) (local) from a native mosquito. Forty countries and regions (give) the certificate so far, according to the WHO.
In the 1970s, through a government project, Chinese scientist Tu Youyou discovered artemisinin, the most (power) anti-malaria drug. breakthrough, based on traditional Chinese medicine, led to a Nobel Prize for Tu in 2015. " Over many decades, China's ability (think) outside the box served the country well in its own (respond) to malaria, and also had a significant effect globally, " notes Dr. Pedro Alonso, Director of the WHO Global Malaria Programme.
