1 . Having worked in the space station core module Tianhe for three months-the longest-ever human space mission in the Chinese history, three “taikonauts” of the Shenzhou-12 crew returned to Earth on Friday, hitting a new milestone in China's space exploration.
China's first self-developed space station, Tiangong, is independently constructed and operated by the country, demonstrating the country's breakthroughs in technologies concerning the astronauts' long-term stay and health care, recycling and life support system, supply of space materials and operations, as well as in-orbit maintenance.
As scheduled, the Tianzhou-3 cargo craft and the Shenzhou-13 manned spaceship will also be launched later this year todockwith the Tianhe module, and another trio of astronauts will stay in orbit for six months. For 2022, China is considering over a blitz of space missions, including the launch of the Wentian and Mengtian lab modules, two cargo spacecraft and two crewed spaceships, for the building of Tiangong, which is planned to be completed next year.
The two decades saw China launch seven manned spacecraft, two cargo spacecraft, Tiangong-1 experimental space lab and Tiangong-2 space lab, and send 12 astronauts into space, with the first “two steps” achieved, and the construction of Tiangong will mark a new peak of China's space technology.
The China Manned Space Agency has worked with the United Nations Office for Outer Space Affairs to invite UN members for scientific experiments aboard the Tiangong station. As the U.S. National Aeronautics and Space Administration(NASA)chief scientist for human exploration and operations Julie Robinson put it, “Increased scientific access to space is of scientific benefit globally, no matter who builds and operates platforms.”
There is no limit for the vast universe, nor for humanity's exploration endeavors. Tiangong, as a new outpost(前哨)in space and a platform for cooperation, will be China's gift and contribution to all humankind.

2 . China is determined to land its astronauts on the moon and set up a scientific station there,according to a project leader.
Zhou Yanfei,deputy chief designer of China's manned space program,said on Friday that China wishes to use the manned lunar missions to carry out scientific surveys and technology demonstrations,explore ways to develop lunar resources and strengthen the nation's space capabilities.
＂A new wave of lunar explorations has been emerging in the world,with participants aiming to make sustainable missions to deepen knowledge of the moon and exploit resources there,"he said in a report delivered at the 2020 China Space Conference in Fuzhou,Fujian province."Unlike other nations,China must depend on its own science and technology to realize our goals."
The country is independently able to land its astronauts on the moon because it has the technologies,a group of well-trained,innovative professionals and high-efficiency research and management systems,Zhou said."However,our existing carrier rockets can't perform landing missions to the moon because they are not powerful enough.The Shenzhou- series manned spaceships are not suitable for lunar expeditions.We don't have a lunar landing capsule,"he said."Our ground support system was designed for operations in low-Earth orbit rather than on the lunar surface.
To solve the problem, we set out to produce a powerful launch vehicle. Zhou said researchers thought about two approaches-making a new heavy-lift rocket,or adjusting the next-generation rocket designed to carry astronauts,which is under development.Researchers prefer the latter approach because it would be easier to design and make and would become operational earlier.
The new rocket is being designed at the China Academy of Launch Vehicle Technology.Its main body will be 87 meters tall,with a diameter of 5 meters,which would make it almost twice as tall as the Long March 5,currently the biggest of China's rockets.

My husband Fred and I moved to a new place. We bought a small house in a reasonably good neighborhood close to Fred’s office. It was a one-and-a-half-floor brick house built for soldiers returning from World War II. That house impressed nobody except me. We had to decorate it first because it was so old. Fred and I started to paint the walls and the doors. I also worked outside the house, helping Fred break the ugly fence between us and the neighbors and grow some flowers.
After I finished painting walls in the bedroom upstairs, I brought up some water and old towels to wash the window. I washed the inside, then opened the window and stepped out on the kitchen roof to wash the outside. The window was the kind that you couldn’t open from the outside.
I was so devoted to my housework that I didn’t realize the window gradually closed. After finishing cleaning, I stood back to admire the clean glass. And then, I tried to open the window, but I failed. Standing on my kitchen roof, I looked around the neighborhood. That was a lovely afternoon. Where were the neighbor kids riding their bikes? They often rode back from the park. No young voices shouted to one another. The neighbor on the left was at work. Carroll and Julie, an elderly couple, lived in the house at the corner and were our nextdoor neighbors. They were likely to be at home, but our kitchen was on the wrong side of our house for me to call them.
I sat down and thought about my situation. Even if someone came along, he couldn’t walk in the house and open the window. The doors were locked. That was my husband’s doing. “When you’re working on an indoor project, anyone could just open the door and come in. So, just keep the doors closed,” he would say. I just needed a rope to get down. I sat there, thinking how stupid I was and wishing a rope would magically appear.

5 . A Great Way to Teach Children to Take Responsibility
As parents, one of the most important things to teach children to take responsibility is to include chores as a part of their daily routine. In order to make a family function smoothly, every member must contribute. Teaching your children to take responsibility at an early age makes it easier for them to shoulder greater responsibilities as they grow older.
Make rewards and punishments a part of the lesson. Together decide whether they will be rewarded or not.
Children need to be taught that there are punishments for their actions in case of not doing their assigned chores. Decide and agree from the start what the punishment will be.
Teaching your children the importance of contributing to the family is of great importance.
| A．A chore is a specific task a child has been assigned which helps improve the life of the entire family. |
| B．And what punishment they will receive if a chore isn’t done. |
| C．Actually you are taking a critical step in empowering them for their future. |
| D．Start by teaching children the difference between a chore and cleaning up after themselves. |
| E．Teach children the importance of each assignment, and why it matters. |
| F．Children will not be rewarded at all for merely cleaning up. |
| G．And if so, what the reward will be for a job well done. |

7 . Why do people undertake volunteer work and what keeps their interest in the work?
Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.
People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people’s wish of participation from an internal factor to an external factor. When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.
Once people begin to volunteer, what leads them-to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.
Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in hospital is an important part of who I am.” Consistent with the researchers’ expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, result in concrete advice: “Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity... Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity.”

8 . Have you ever had a burger without meat? You might think that a vegetable burger will take away the real meaning of a burger as it will not have the juicy taste of meat. Despite these concerns, the company, Beyond Meat, has managed to successfully make plant-based meat.
On May 2, the company became the first vegan company to become public. Beyond Meat’s initial share price was expected to range from $19 to $21. Impressively, just hours later, Beyond Meat’s stocks rose to $73!
Instead of killing animals, Beyond Meat obtains these components from different plants and combines them to make vegan meat. It contains pea protein that gives the chewy, meaty texture along with canola oil, coconut fat and other binding agents. In addition, the company uses beet juice to simulate the bloody look of beef! The plant proteins are subjected to intense heating, cooling and pressure so that their structure becomes fibrous and copies that of animal meat.
For people who have changed their diet but miss the taste of meat, Beyond Meat satisfies their taste buds. It also has all the nutrients and elements that meat has, but does not come from an animal.
Plant-based meat is also beneficial as fewer animals are killed. As our world’s population continues to grow beyond 7 billion, so does the demand for meat. Livestock farming is not sustainable as it requires more land, consumes more energy and is one of the largest producers of greenhouse gases. Beyond Meat uses 99 percent less water and 93 percent less land. It also has 90 percent fewer greenhouse gas emissions, and it uses 46 percent less energy.
However, there are some people who do not like the smell of a Beyond Meat patty. Others question that processed foods are unhealthy and it is safer to choose whole vegetables instead. Regardless, with another company, Impossible Burger, looking to go public soon, as well as companies such as Tyson Foods and Nestle looking to enter the market, plant-based meat is here to stay. These companies hope to convince many people to switch from meat to plant-based alternatives.

9 . One day, gardeners might not just hear the buzz of bees among their flowers, but the whirr of robots, too. Scientists have managed to turn an unassuming drone (无人机) into a remote-controlled pollinator (授粉媒介) by attaching horsehairs coated with a special, sticky gel to its underbelly.
Animal pollinators are needed for the reproduction of 90% of flowering plants and one third of human food crops. Chief among those are bees — but many bee populations in the United States have been in steep decline in recent decades. Thus, the decline of bees isn't just worrisome because it could disrupt ecosystems, but also because it could disrupt agriculture and economy. People have been trying to come up with replacement techniques, but none of them are especially effective yet.
Scientists have thought about using drones, but they haven't figured out how to make free-flying robot insects that can rely on their own power source without being attached to a wire. “It’s very tough work,” said senior author Eijiro Miyako, a chemist at the National Institute of Advanced Industrial Science and Technology. His particular contribution to the field involves a gel, one he’d considered a mistake 10 years before and stuck in a storage cabinet. When it was rediscovered a decade later, it hadn’t dried up or degraded at all. “I was so surprised because it still had high viscosity,” Miyako said.
The chemist noticed that when dropped, the gel absorbed an impressive amount of dust from the floor. Miyako realized this material could be very useful for picking up pollen (花粉). He and his colleagues chose a drone and attached horsehairs to its smooth surface to mimic a bee’s fuzzy body. They coated those horsehairs in the gel, and then controlled the drones over lilies, where they would pick up the pollen from one flower and then deposit the pollen at another one, thus fertilizing it.
The scientists looked at the hairs under a scanning electron microscope and counted up the pollen grains attached to the surface and found that the drones whose horsehairs had been coated with the gel had about 10 times more pollen than those that had not been coated with the gel.
Miyako does not think such drones would replace bees altogether, but could simply help bees with their pollinating duties. There’s a lot of work to be done before that's a reality, however. Small drones will need to become more controllable and energy efficient, as well as smarter, with better GPS and artificial intelligence.

10 . “Birds” and “airports” are two words that, paired together，don’t normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that is for birds.
Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区）in the northern coastal city of Tianjin is, of course,not an actual airport. Rather，it's a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway. Over 50 species of migratory (迁徙的）water birds，some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.
Located on a former landfill site，the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However，instead of duty-free shopping，the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles.
“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city---China’s fourth most populous----that would certainly benefit from a new pair of healthy green lungs•
