4 . The periodic table of elements is a common sight in classrooms, campus hallways and libraries. The mode periodic table arranges the elements by their atomic numbers and periodic properties (周期性). Several scientists worked over a century to assemble the elements into this format.
In 1789, French chemist Antoine Lavoisiertried grouping the elements as metals and nonmetals. Forty years later, German physicist Johann Wolfgang Dobereiner observed similarities in physical and chemical properties of certain elements. He arranged them in groups of three in increasing order of atomic weight and called them triads, observing that some properties of the middle element, such as atomic weight and density, approximated the average value of these properties in the other two in each triad.
A breakthrough came with the publication of a revised list of elements and their atomic masses at the first international conference of chemistry in Karlsruhe, Germany, in 1860. They concluded hydrogen would be assigned the atomic weight of 1 and that the atomic weight of other elements would be decided by comparison with hydrogen. For example, carbon, being 12 times heavier than hydrogen, would have an atomic weight of 12.
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the moder periodic table, leaving gaps for elements that were yet to be discovered. Mendeleev predicted the properties of some undiscovered elements and gave them names such as “eka-aluminum” for an element with properties similar to aluminum. Later “eka-aluminum” was discovered as gallium.
German chemist Lothar Meyer produced a version of the periodic table similar to Mendeleev’s in 1870. He left gaps for undiscovered elements but never predicted their properties. The Royal Society of London awarded the Davy Medal in 1882 to both Mendeleev and Meyer. The later discovery of elements predicted by Mendeleev verified (证实) his predictions and his periodic table won universal recognition. In 1955 the 101st element was named mendelevium in his honor.
On UNESCO website, it wrote, “The Periodic Table of Chemical Elements is more than just a guide or catalogue of the entire known atoms in the universe; it is essentially a window on the universe, helping to expand our understanding of the world around us.”

Most people think that procrastination (拖延症) is a negative habit. But people like me who routinely put off doing assignments, are likely to defend our “slower” approach to getting tasks done.
I'm the only procrastination in my family. My parents and sister were all born with the “do it right now” gift. They are always in a rush, as if closely rushed by an invisible deadline. Personally, I prefer a more relaxed pace. When my parents voiced their concern about my tendencies, saying “Don’t put off until tomorrow what you can do today,” “No way!” I responded, confidently presenting my research as a defense. It said people procrastinated when they need to solve a problem or commit to a topic or project. In these cases, delaying a decision can be beneficial. This was because our minds continue to reflect on problems even when we were not actively thinking about them, which could lead to more creative solutions. My findings filled me with satisfaction and pride. My method of getting things done was just as good as my sister’s…or so I thought.
At school we’d been talking about architecture and design. As part of the final assessment my teacher Mr. Smith announced an exciting project that each student would have a month to complete. We were expected to choose our materials, construct a small building and make use of things we had learned in class. Not only would the winners receive extra credit, but the winning constructions would be proudly displayed in the cafeteria. “I have no clue how I could get it done,” my friend Nate sighed in despair. I didn’t say anything. Not because I shared his anxiety-but because I was not nervous at all. I loved hands-on projects! Picturing my brilliant work exhibited in the cafeteria, I was fully convinced that I would definitely produce something that could impress everyone. So relaxed was I that I didn’t give it a second thought for weeks.

8 . A program at Virginia Commonwealth University (VCU) is hoping to fight against loneliness brought on by the pandemic by forming friendships between students and seniors in the community. They’re making it possible through weekly calls.
“It’s been a thing I look forward to every week,” Miranda Savioli, a VCU medical student said.
The program is run by students involved with the American Geriatrics Society and pairs medical and health science students with seniors in the community.
VCU education administrator for the School of Medicine, Chuck Alexander, says it was formed to fight against loneliness and give students valuable interaction with that age group — something that’s been missing since training programs stopped earlier this year. “It’s mostly just social — just chatting,” Alexander said. “A lot of times they just need someone to talk to. A lot of times they feel that they have a connection with someone younger who is just entering a new phase in their career and that they have some wisdom to impart to them — medically and socially as a friend.”
So far, the volunteer program has paired around 40 students with seniors.
Every week, Savioli video calls retiree Joan Kerby, who lives in a retirement community in Henrico.
“It’s a really good connection because in lockdown you really don’t have long conversations with anybody,” Kerby said. Those long conversations soon turned into a visit. The two participants decided to meet in person back in November and Kerby said it was a special moment. “We talked for two hours. We probably could have gone on longer but we had to stop,” Kerby said.
Savioli says they plan to keep the program going, and encourages others to pick up the phone and call a loved one who may be isolated. “It was developed to help seniors with isolation, but mean, we all got isolated during this pandemic,” Savioli said. “It’s been nice to talk to someone every week.” The group has no plans to stop the program. “We’re going to keep the program going and as for Joan and I, we’ve established ourselves as lifelong friends,” Savioli said.

10 . You probably consider calorie (卡路里) burning with training. You can get great calorie burning effects with the following exercises.
RunningRunning is one of the best calorie burners out there. An average person can burn anywhere from 500 to 1,000 calories in one hour of running. Speed and pace are all factors that can affect calorie burning. But running uses every muscle group in the body, allowing you to burn more calories.
High Intensity Interval (高强度间歇运动) Training (HIIT)If you want intensity, HIIT is right for you. This physical exercise involves working hard in intervals, then resting. Because your heart rate will stay at a high level, you’ll burn more calories in less time. On average, a person will burn 400 to 600 calories in 30 minutes.
Jumping ropeThis childhood activity can actually do wonders for your health. Jumping rope is great for strengthening the lower and upper body while training your balance and coordination (协调能力), because your mind has to work while you jump. Jumping rope can burn 600 to 1,000 calories in an hour.
SwimmingSwimming is a low-intensity form of exercise that also uses muscle groups of your body. In just 30 minutes of swimming, an average person can burn 200 to 300 calories. Swimming also helps to shape body, control blood pressure, and increase strength—all great reasons for you to jump into the water.
1. Which kind of exercise burns the most calories in an hour?A.Running. | B.Swimming. |
C.Jumping rope. | D.High Intensity Interval Training. |
A.Those who want to train their mind. | B.Those who want to have good balance. |
C.Those who want to control blood pressure. | D.Those who want to do low-intensity activities. |
A.To encourage people to compete in sports. | B.To teach people how to do exercise. |
C.To provide ways to burn calories. | D.To promote a healthy lifestyle. |
