    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association(APEX) spoke to around 1,500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia and Brazil.

The results found Chinese travelers are most likely to nod off once the seat-belt sign switches off. They are also the first to take out their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively—- when not drinking—- choosing to work while flying at 35,000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers—-spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via email, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection of in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey. ” he added. 

    Last week I was riding my special motorbike and then stopped at a convenience store. As I was getting my wheelchair off the back, a man watched me from his car and I noticed a wheelchair in his back seat. We spoke for a moment and I asked him about the wheelchair. He answered that it was for his daughter. "Well, do you think she would like to go for a ride on my motorbike with me?" I asked. He seemed shocked that a total stranger would ask him this. He thought about it for a second and said, "OK, as long as I can follow you."

    He introduced me to Amy and he sat her on my back seat. Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas. As we came back to the convenience store, she said, "This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn't know I could do this." I told her about some of the other things I do (ski, travel the world by myself, etc.). As her father was taking her off my bike, she turned to him and said, "Oh Daddy, I'm going to be OK. Mr. Bryant does all kinds of things, and I will too." Her father turned away as a tear of joy rolled down his cheek. He hugged me and said, "I was sitting here praying for a gift for Amy that would encourage her. She often felt that her life was dull compared to other children. God answered my prayer just now. Now I pray that God will bless you for your gift to Amy today." I believed what he said. Being kind and thoughtful to others, we can be an answer to prayer.

Fishy Weather Conditions

    Laj amanu, Australia, is a dry little town, sitting right on the edge of the Tanami desert. Can you imagines how surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado, only it forms above oceans, lakes, or rivers. Like a tornado, a waterspout moves in a circle at high speeds. When it moves above the water, it tends to carry the fish with it, as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still, the fish in Honduras were very much alive when they rained down to the ground, but they were all blind. In England and Australia, it rained fish and snakes, and none were blind. It was difficult to puzzle out, but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep, underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras, scientists began to connect some dots. Clearly, these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent, and each time, people have tried in various ways to explain this strange phenomenon. Historically, villagers thought the “fishes from the heavens” might be answers to prayers for food.  Others suggested that floods overran river banks and oceans, leaving the fish on the city streets. No scientist had actually seen the rain as it occurred, only the fish left on the ground. But in 1990, a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.

    It is increasingly popular for Chinese young people to share their experiences on Social media, such as the “moments” (朋友圈) on popular instant messaging service WeChat.

    “I have been reading 'Jane Eyre' for 40 days with 48,000 words finished,” Li Anqi said. Li has been sharing her reading experience on WeChat moments every day since January. Working in Yinchuan, capital of Northwest China's Ningxia, Li wants to learn English very much, but cannot bare (摆脱) the daily grind (日常工作) of school lessons.

    “I found many of my WeChat friends had been reading books or learning English on mobile reading apps, and I did not want to fall behind,” Li said.

    In January, she spent more than 100 yuan purchasing an online reading class at the Bohe Reading app, which tells customers they can: “Finish reading your first English book here.” At the reading class, teachers assign reading homework and give instructions to 430 class members every day.

    A survey report released (发布) on Thursday said 70.9 percent of primary and middle students in China use the Wechat instant messaging App. At the same time, 75.9 percent of Chinese children have their own mobile phones, according to China National Children's Center.

    The figures were based on a survey of nearly 9,000 children across China. However, 28.8 percent of them never read news online and 43.2 percent have never touched newspapers.

    The Center called for efforts to address the digital divide between urban and rural education and protect children's privacy as Internet users.

The outbreak of locusts, an insect that mainly lives in Africa and Asia, is the worst experienced by Kenya in 70 years. The crowds are some three times the size of New York City, eating their way through thousands of acres of crops and animal grassland and destroying livelihoods in the process.

"These hungry things are alarming," says Keith Cressman, the UN Food and Agriculture Organization's senior locust forecasting officer. "A crowd the size of Manhattan can, in a single day, eat the same amount of food as everyone in New York and California combined."

Desert locusts are infamous for their ability to breed(繁育)rapidly in large numbers every three months. And with some help from the wind, they can travel as much as 80 miles a day. Most years, the insects stay in African deserts. However, under the right environmental conditions, they can multiply quickly, spread as much as 400 times every six months and cause extensive destruction if left unchecked.

"The insect has the ability to take advantage of good conditions." Cressman says.

The "good conditions" the scientist is referring to began in mid-2018 when a rainstorm from the Indian Ocean struck a remote area of the Arabian Peninsula known as the "Empty Quarter". Normally, it would dry out within a short period, killing most of the locust population, which depends on green plants for food. However, in late 2018, a second rainstorm struck the same region. The huge sandy area got wet, which is exactly what desert locusts need to lay their eggs and breed. The extra food supply caused the population to explode for the second time in six months.

Luckily, the locusts, experts say, are easy to control with chemicals. Kenya badly needs equipment and a steady supply of chemicals to effectively wipe out the massive insects. Hopefully, leaders worldwide will recognize the tough situation and contribute generously to control the locust outbreak.
