Dutch designer Daan Roosegaarde has spent much of his time seeking artistic solutions(解决方案)to solve our environmental problems. His past projects include "Bioluminescent(生物发光)Trees" to light streets, a "Smog-Free Tower" to clean Beijing's polluted air. and "Gates of Light". which uses the headlamps of passing cars to light up the 60 floodgates of the Afsluitdijk, a major dam in the Netherlands. Now, he is hoping to use his skills to solve a pressing global problem-space junk!
Scientists guess that there are over 500，000 bits of large rubbish. To deal with the problem, Roosegaarde intends to achieve his goal by educating the public about the need of the situation and coming up with possible solutions. The plan. called the Space Waste Lab. started in October 2018 with a laser(激光)show in the Netherlands. The unique outdoor artwork of LEDs used real-time tracking information to point at pieces of space junk floating at altitudes of 200 to 20,000 kilometers. The experience was designed to make the public know more about how much space junk there are.
To find a solution, the designer has been thinking with experts. One of the projects being considered is "Shooting Stars"，which attempts to reintroduce the trash to the atmosphere in a controlled way. Upon reentry. the waste would burn in the atmosphere like a shooting star. Roosegaarde envisages that if successful .burning space trash could someday replace fireworks at large public events!
In September 2018。the RemoveDEBRIS satellite successfully sent a net to catch a target while orbiting at an altitude of about 300 kilometers(190 miles). Sometime this year. the capsule will set free a harpoon that has been designed to remove space trash. At the end of its task，RemoveDEBRIS will let go a sail to bring the satellite itself and hopefully some trash, back into the atmosphere where it will burn up.

In 1992, Teen Talk Barbie was released with the controversial voice fragment, “Math class is hard.” While the toy's release met with strong public reaction, this underlying assumption persists, spreading the myth that women do not thrive in science, technology, engineering and mathematic (STEM) fields due to biological inadequacies in math aptitude. However, in 2019 Jessica Cantlon at Carnegie Mellon University led a research team that comprehensively examined the brain development of young boys and girls and found no gender difference in brain function or math ability.
Cantlon and her team conducted the first neuroimaging study to evaluate biological gender differences in math aptitude of young children. Her team used functional MRI（核磁共振）to measure the brain activity in 104 young children (3-to-10-year-old; 55 girls) while watching an educational video covering early math topics, like counting and addition. The researchers compared scans from the boys and girls to evaluate brain similarity. In addition, the team examined brain maturity by comparing the children's scans to those taken from a group of adults (63 adults; 25 women) who watched the same math videos.
After numerous statistical comparisons, Cantlon and her team found no difference in the brain development of girls and boys. In addition, the researchers found no difference in how boys and girls processed math skills and were equally engaged while watching the educational videos. Finally, boys' and girls' brain maturity were statistically equivalent when compared to either men or women in the adult group.
Cantlon said she thinks society and culture are likely steering girls and young women away from math and STEM fields, as previous studies show that families spend more time with young boys in play that involves spatial cognition（空间认知）. “Typical socialization can make worse small differences between boys and girls that can snowball into how we treat them in science and math,” Cantlon said. “We need to be aware of these origins to ensure we aren't the ones causing the gender inequities.”
However, this project is focused on early childhood development using a limited set of math tasks. Cantlon wants to continue this work using a broader scope of math skills, such as spatial processing and memory, and follow the children over many years.

It is with mixed emotions that I went to the young criminal center every few months to give vaccinations (接种疫苗). On the one hand, I feel lucky to be able to provide a service that may have a positive health effect on the residents. But, on the other hand, I feel a sense of sadness and disappointment as I see the prisoners being escorted (押送) by guards to the nursing unit.
My last visit was very memorable. For some reason, there was a lightness in the air. More than ever before, I felt a lightness as I spoke with each person. We shared stories and smiles and fears. Even the toughest prisoners seemed to be surrounded by light. As a mother, I saw them as not only youth, being punished for crimes, but also as children who have the potential to change for the better. Most of them wanted to talk longer! They were reaching out to us! It felt right.
There was one more prisoner. He was limited to a different unit in a lonely cell. We were asked if we were okay going down there. We said that we were. Two guards escorted us down and when we entered the area, instant tears welled up in my eyes. The area was sad. These guards didn’t smile. We entered the cell and had to make do with what was there.
We were done but I didn’t want to leave. I gave the 17 year old a gentle touch and smile as I explained what to do regarding the side effects. At first, there was no response, so I just looked down at his bare feet and then to my supplies. I thought that I had better pack up. Suddenly, he looked up at me and smiled before he said “Thanks” and then he gave me a thumbs-up. I smiled back and said, “You’re welcome. Take care of yourself.”
It was wonderful to receive a kind response from someone who was in such a harsh place. As we walked back to the main entrance, we didn’t speak. Where there can be a smile, there is hope. Sometimes smiles can be very powerful.

One day I happened to find chatting room on my QQ, that people were chatting in English. I tried to chat with some of them. To my surprised, I found the oral English of some junior students were better than mine. I asked them for advices and they told me to practise more on QQ. But every day after that I would spend one hour practise my oral English on QQ. Day by day I learned from many useful words and expressions. With time going by, I found that I could even communication with some college students free.
