The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid—we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ''

    But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

Song Chunfang still remembers his teacher Yuan Longping, known as the "father of hybrid rice," telling them to speed up the promotion of hybrid rice in Madagascar before their trip to the country in October 2020.

Yuan Longping, famous for developing the first high-yield hybrid rice strain capable of eliminating (消灭) hunger for large numbers of people, died of organ failure at 91 on May 22, 2021.

In April 1979, Yuan presented his paper to an international academic conference on hybrid rice in Manila, sharing China's experience in hybrid rice research with the rest of the world. Over four decades, research teams working on hybrid rice have been promoting the technology overseas. So far, Yuan's hybrid rice has been grown in more than 60 countries, with a total growing area of 8 million hectares (公顷) outside China, according to the China National Hybrid Rice R&D Center where Yuan worked.

Established in Madagascar in 2019, the African sub-center is the only overseas sub-center of China's national hybrid rice engineering technology research center, and it is functioning well. Chinese experts in the sub-center set up a service chain including providing seeds, relevant training and technical guidance. More than 100 skilled local trainees were given online courses to become hybrid rice experts who can better serve the needs of local farmers. So far, the sub-center has approved three hybrid rice varieties in Madagascar, with two other varieties suitable for growing in most regions of the country expected to gain approval this year.

Many parents happily paid a lot of money, only       the tours were not rewarding enough for their children.

    NASA has big plans for returning astronauts to the moon in 2024, a stepping stone on the path to sending humans to Mars. But where should the first people on the Red Planet land? While there are lots of places on Mars scientists would like to visit, few would make practical landing sites for astronauts. Thanks to the researchers, their newly-published paper in Geophysical Research Letters will help by providing a map of water ice believed to be as little as an inch (2.5 centimeters) below the surface.

    Water ice will be a key consideration for any potential landing site. With little room to spare aboard a spacecraft, any human missions to Mars will have to harvest what's already available for drinking water. Liquid water can't last in the thin air of Mars. With so little air pressure, it turns from a solid to a gas when exposed to the atmosphere. On this planet, water ice is locked away underground. Buried water ice changes the temperature of the Martian surface, so the study's authors relied on heat-sensitive instruments to find ice that astronauts could easily dig up. The authors of the new paper make use of data from spacecrafts to locate water ice that could potentially be within reach of astronauts on the Red Planet.

    The paper's lead author, Sylvain Piqueux of NASA's Jet Propulsion Laboratory in Pasadena, California said, ' 'We're continuing to collect data on buried ice on Mars, aiming to find the best places for astronauts to land.” Piqueux is planning a comprehensive campaign to continue studying buried ice across different seasons, watching how the abundance of this resource changes over time.

    The story happened in ancient times. A king was so clever that he thought of a good way to test  his men were reliable.

    One day, he had a huge rock  (place) on a roadway at night. Then he hid  (him) nearby and watched carefully to see if anyone would remove the big rock. Some  (wealth) businessmen and high officials came by, but they simply walked around it. Many of them even loudly blamed the king for not keeping the roads clear, but none of them would bother  (get) the big stone out of the way.

    Then a villager came along carrying a load of vegetables. On  (approach) the big rock, he stopped and laid down his burden, trying hard to move the stone to the side of the road. After much pushing, he  (final) succeeded. As the villager picked up his load of vegetables, he noticed a purse lying in the road where the rock  (be). The purse contained many gold coins and a note from the king, saying that the gold was for the person  removed the huge rock from the road.

    The villager learned a valuable lesson that many others would never understand: Every obstacle presents  opportunity to improve one's condition.

As the oldest of three children, I never had any hand-me-downs to wear like other poor kids. Instead, Mom got my wardrobe (行头) from neighborhood mothers. Imagine the fun other kids had when they saw me wearing their used clothing.

Perhaps my biggest challenge came from Charlie. As far as I was concerned, Charlie's main fun was to make fun of me. During those years, I slowly learned to hate. I hated Charlie, but I also hated myself for not being able to change my situation.

But situations do change. That chance came after high school when I joined the Navy. The Navy made me a social equal for the first time in my life, and the GI Bill gave me a college education. Hard work and a few lucky career (职业) choices finally lifted me into the middle class. I found myself living the American Dream.

One beautiful summer afternoon, my friend and I celebrated Friday in Jackson's Steak House. For the first time in almost twenty years, I saw Charlie. Not only did I see him, but he spoke to me. I could tell he didn't recognize me, but I surely recognized my childhood tormentor (摧残者). His words were short, but I'll never forget them. He said, "Sir, what kind of dressing would you like with your salad?"

The tables had turned. Charlie was calling me "Sir." While hundreds of improper ideas raced through my mind, I could only give a two-word reply: "Blue cheese." As much as I wanted to taste the sweet taste of revenge (复仇), I refused to do it. I wouldn't put another person through what I had gone through as a child. It was time to put childish things behind me and make use of the new opportunity that life had given me. I left him a good tip and I didn't say one word about recognizing him.
