The answer to protecting and saving marine(海洋) wildlife can start with cutting back on something Americans use every day—plastic drinking straws. Actor Adrien Grenier, best known for playing Vincent Chase in 2015 movie Entourage, has launched a campaign to reduce the amount of single-use plastic usage in this country in order to protect and save marine wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the shocking loss of marine life, but they're a great place to start because they're something Americans are using by the hundreds of millions without any awareness that they're so damaging.

According to Ecocycle, an international environmental organization, Americans use more than 500 million straws daily, which are enough to fill 127 school buses each day, and they can't be recycled. They means plastic straws end up in landfills or oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a whale beached on the shore with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges facing marine life.

     Along with stopping the use of straws, Grenier hopes to educate consumers on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are more sustainable alternatives that can help protect the environment. Ecocycle recommends the use of straws made from stainless steel, glass, and even bamboo instead of plastic. You can buy a number of these environmentally friendly straws online and in stores.

    One May morning, 10-year-old Khadab played in the ruins of a school near his home in northern Iraq. He saw something that looked interesting. It was yellow and plastic and looked like a ball. He reached for his new toy and, BANG!

    The last thing he remembered was a big noise. When Khadab awoke, he was in hospital. His parents stood sadly by his side. They told him he had picked up an unexploded bomb. When it exploded, Khadab lost an arm.

    He was just one of hundreds of Iraqi children who have been injured or killed by stepping on and picking up explosives left over from the war.

    These landmines (地雷) and bombs have injured and killed at least 15 people a day since Saddam Hussein's government fell on April 9. And children are the most affected.

    Iraq is among the worst landmine-affected countries in the world. Many villages in the war-torn areas are surrounded by minefields (雷区). These landmines lie on the ground between rocks, up in trees and on riverbeds.

    Even though the war in Iraq is over, many children have not returned to school. They can be seen walking the streets with the natural curiosity of young kids. Their new playgrounds are places where the fighting took place. Many boys can be seen playing with unexploded bombs. A new game is to throw the bombs and run away. Some of them get away, but too many are killed. They do this for fun, and don't realize the dangers until it's too late.

    UNICEF (联合国教科文组织) has warned children, through the TV, of the dangers of landmines and unexploded bombs in Iraq. They hope to make children aware of the dangers they face.

    “I can't imagine there's going to be a classroom in the north without scared children in it. It's so widespread,” said Sean Sutton of the British-based Mines Advisory Group (MAG).

    MAG is an organization working to clear unexploded bombs and landmines in war-torn areas.

    It is difficult to report the exact number of deaths. Sutton said MAG found 320 injuries in northern Iraq in the first month after April 9. But he said the real figure was probably much higher.

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

The Peony Culture Festival of Luoyang

    Spring is time for people to go out and see blossoming flowers. Luoyang in Henan, China is famous for peonies, the city's official flower. The city's annual Peony Culture Festival begins in early April and lasts till early May. Peonies are in full bloom during the event, which was first held in 1983.

    You can go to the Luoyang National Peony Garden. The peonies there are known for their rich colors and long florescence. Don't miss the 1,600-year-old "Peony King"!

    Chinese Language Day

    Chinese is one of the six official working languages of the United Nations. The LIN has set different days for these languages to promote their uses. It holds exhibitions, shows and other activities. In 2010, the first Chinese Language Day was held on Nov. 12. But since 2011, it has been held on April 20. The date is close to Grain Rain, one of the 24 solar terms. It means "rain of millet". People celebrate Grain Rain to remember Cangjie, a mythical character. Many people believe that Cangjie was the first person to write Chinese characters. When he did this, it rained millet and saved people from hunger.

    China Astronautics Day

    On April 24, 1970, China's first man-made Earth satellite — Dongfanghong I — went into space. It was a big step for China's space program. In 2016, the government set April 24 as China Astronautics Day. Many events are held across the country to celebrate this special day. For example, astronauts and scientists will give talks to students. Some cities will hold exhibitions about space development.

    Last year, China had big plans for its space program. On December 8, it launched its second lunar rover（月球车）as part of the Chang'e 4 space mission, which landed on the far side of the moon.

    In its early history, Chicago had floods frequently, especially in the spring, making the streets so muddy that people, horses, and carts got stuck. An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."

    The city planner decided to build an underground drainage （排水） system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.

    An engineer named Ellis Chesbrough convinced the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12feet.

    This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?

    That's where George Pullman came in. He had developed some house-moving skills successfully. To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10jackscrews.At Pullman's signal each man tured his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening.

    Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.

In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's famous Sardine Run off the coast of Port Elizabeth. The migration of billions of South African sardines, is a big draw for hunters, especially seabirds and dolphins. The two species work together to herd the large group of fish into smaller shoals (浅滩), which are then eaten by not just the birds and the dolphins, but also sharks and Bryde's whales.

In an attempt to find the best scene of the amazing natural phenomenon, which has been the subject of many films, Rainer got into the middle of a swirling ball of fish. Suddenly the sea churned (翻腾), and the experienced diver and his photographer Heinz Toperczer, who was filming from the boat, instantly realized something strange was going on.

Toperczer later said, "As Rainer moved towards the shoals, suddenly the water churned widely up, dolphins shot out of the water and then a whale appeared and caught him!"

Rainer, who was swallowed in darkness inside the whale's mouth, was trying to survive. "I held my breath because I thought he was going to dive down and release me much deeper in the ocean," the diver said.

Fortunately for Rainer, the whale quickly realized he was no sardine! "I felt huge pressure around my waist (腰部) which is when I guess the whale realized his mistake," he said. "As the whale turned sideways, he opened his mouth slightly to release me, and I was washed out, together with tons of water, of his mouth." Though the entire event lasted just 1. 8 seconds, it felt like a century to Rainer.

Still holding his underwater camera, the diver swam to his boat, where he was quickly rescued by the members of the team. The terrifying adventure did not worry Rainer for too long. After checking to ensure he had no injuries, the diver returned to the water. Fortunately, the rest of the adventure went peacefully.
