Adorable baby giant pandas are always curious about the world and love to play around. Recently, in southwest China’s Chengdu Research Base of Giant Panda Breeding, a baby panda was caught on camera getting his head stuck behind a log.
The panda tried to pull his head through the gap at first but couldn't manage to pass through it. Later, the breeder came to rescue him by pushing his bottom instead and nagged this little cutie constantly like a mother, but the baby panda continued to act cute, melting all panda lovers’ heart!
Click on this video to see the warm and sweet interaction between the breeder and the naughty baby panda!

6 . I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that something was wrong, and ran down to the edge of the near bank. There I saw Ma Shwe with her three-month-old calf (幼崽) struggling in the fast-rising water, and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body against the rushing water, and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort, she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment she fell back into the river. If she were carried down, it would be certain death. I knew, as well as she did, that there was one spot where she could get up the bank, but it was on the other side from where she had put her calf.
While I was wondering what I could do next, I heard the sound of a mother’s love. Ma Shwe had crossed the river and got up the bank and was making her way back as fast as she could, roaring (吼叫) all the time, but to her calf it was music.

7 . There are many beautiful places in Europe worth visiting. Among them Greece is right at the top. A vacation to Greece will give you everything you ever want in a holiday. The attractive hot springs, beautiful villages, rich history, delicious seafood and beautiful beaches are all here. The streets are always alive with music, fireworks and celebrations. Winter is the time to enjoy some great skiing, with so many mountains around here that offer this sport.
Spain is the second largest tourist destination (目的地) in the world. It’s one of the first countries in the world to develop summer beach vacations. Spain, along with Italy, officially has the most world heritage sites, 42 to be exact. With so many mountainous regions, Spain is big when it comes to the winter vacation. Lastly, for great nightlife, you’d love to be in Barcelona or Madrid.
Switzerland is the most popular winter destination in the world. It has 15,000 miles running through mountainous regions. The Swiss Alps attract people from all over the world. If you think Switzerland is only a winter holiday destination, you，re mistaken. The same places are popular in summer too. Hiking is popular in summer. Switzerland is also proud of Jungfraujoch — the highest train station in Europe. Switzerland has developed an amazing transport network, and each and every mountain village can be got to by some kind of public transport.
Venice of Italy is another great destination. It has an amazing history and is famous for its beautiful architecture. There are many old churches worth visiting. Venice is also filled with many art galleries. The Grand Canal is a long canal that runs right through the city. This is referred to as the most beautiful street in the whole of Venice. The city, made up of 117 small islands, is amazingly linked by 400 bridges over 150 canals.

8 . Friendship is an important part of human life. Friends can share our joys and sadnesses. We aren't alone. Many different animals also make friends.
Recently, a British research team finished an eight-year study of Indo-Pacific dolphins off the coast of Western Australia. These dolphins can use different tools to search for food. The researchers found that these dolphins are more willing to hang out with partners that like the same tool. Other factors, like family closeness or sex, have no impact on this relationship. It suggests that dolphins form social bonds based on shared interests.
Apart from dolphins, elephants and horses are also known to form friendships. Are friendships only limited to the same species?
Of course not, The Atlantic reported. In 2015,Timur, a goat, was left in the enclosure（围场） of a tiger, Amur, as a meal. But instead of eating Timur, Amur liked to play with him and got angry when others were close to his friend. That's because in captivity(圈养）, animals don't need to spend much time and energy marking their land or looking for mates the way they would in the wild. They are actually more likely to feel bored.
More interestingly, animals not only make friends but also try to keep lasting friendships. Take bats for example. In 2011, scientists found bats often hang out with a few particular friends, keeping loose ties to the rest of their group. Humans are different. "We do not work, play and live together with the same friends all the time," Swiss zoologist Gerald Kerth explained. "But nevertheless, we are able to maintain long-term despite our often highly dynamic（充满活力的）social lives."

9 . Commercial airlines alone contribute around 3% of total global carbon emissions. But the industry is actively looking for green solutions in the form of sustainable jet fuel, and in one case, that fuel may have had a previous life as your household food waste. In a study released this week in the Proceedings of the National Academy of Sciences, researchers detail a method of transforming food waste into sustainable jet fuel that can be used in existing engines.
Biomass (生物质), such as manure (粪便) and food waste, can be transformed into bio-fuels, which are renewable liquid fuels made from organic matter. Derek Vardon, a senior research engineer at the National Renewable Energy Laboratory (NREL), says that their fuel worked as a mixture of 90% conventional petrol jet fuel and 10% alternative jet fuel required by the industry currently. They also show they could push it to a 70/30 mixture, which will be possible in real world with more time and testing.
Major airline companies are eager to get involved in sustainable aviation fuel because some sustainable solutions, such as battery-operated commercial planes, just aren’t possible yet with current battery technology. A battery-powered plane would be too heavy to fly long distances, so fuel that works in the same way as the fuel we have is a simpler way to trade out emission-heavy fossil fuels.
Vardon says that because the wet waste used in the process would normally go to a landfill (垃圾填埋场) and break down to release greenhouse gases, the process of making and using sustainable aviation fuel could actually have a negative carbon footprint when scaled up.
Commercial airlines are on board to find an affordable and sustainable solution to the carbon-intensive process of air travel. Airlines are looking to hit aggressive sustainability goals by 2050, including decreasing net carbon dioxide emissions by 50%.
