“As a scientific term, free radicals are essentially unstable atoms, “says Arizona-based doctor, Natasha Bhuyan, M. D. “In medicine, they cause cells to break down over time and are linked to aging.”

A super simple chemistry review for you: Atoms from different elements are the building blocks that make up water, nitrogen and more. Electrons (电子) are the negatively charged atoms, and they like to be in pairs. When an electron loses its partner, it creates a free radical, which is usually unstable and highly reactive. Free radicals typically go through the body to seek out a replacement for their missing electron, and that can result in damage to cells,proteins and DNA.

So how do free radicals form and why do they happen? Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with. The theory behind free radicals is that they can lead to the imbalance between free radicals and antioxidants (抗氧化剂).” Another mini-science lesson for you: Antioxidants are natural or man made matters that can help delay or prevent some types of cell damage. They’re often found in fruits and vegetables.

A lot of the aspects of modern life — our diet, lifestyle and environmental factors like pollution, can cause oxidative stress.

Do your work

【2】 But especially in times where businesses and organizations are having to make hard decisions about who to keep, doing your work — and doing your work well — is necessary.

Tell others

I don’t recommend that you give yourself a shout out at every single meeting. But if you have accomplished something important, share it. That could look like covering a few highlights of your work with your boss each week, either in your one-on-one or through email. 【3】 And this gives you increased visibility across the organization as people understand the role that you fill and the value you add.

【4】

Although you don’t want to overload yourself with extra work, look for ways to make your boss’s life easier. For instance, turn in your work early so your manager has extra time to review it before a meeting. These little things can help reduce the pressure on your boss.

Much of what happens with the job market and your particular job will be out of your hands. You can’t control what businesses are considered necessary or not. And there are many factors in place that determine the market demand for your work. However, if you follow pieces of advice above, 【5】

A.Set your goal

B.Help your boss

C.I can appreciate your concern.

D.you’ll share your work with others.

E.Focus on what you did for your organization.

He has got up at 5:30 a.m. to head to the outdoor court and play basketball since he was 9 years old. Zion's hard work began to pay off when he entered high school, where he became a YouTube hit for his high-flying dunks （灌篮）and powerful moves. But Sampson wanted her son to not only work hard at being great but study how the legends of the game went about their skills.

“When I started playing, my mom said there were three players she wanted me to watch — Magic Johnson, Larry Bird and Michael Jordan,” Williamson said. “Even though I wasn't alive when he （Jordan） was doing those things, it just attracted me. Everything he did was just incredible.”

The national spotlight shined on Zion during his one year of collegiate basketball at Duke University, where he was coached by five-time national champion Mike Krzyzewski. The most storied rivalry in the collegiate game is between Duke and North Carolina, where Jordan won a national championship back in the 1980s.

Shortly after his freshman season, Zion declared for the NBA Draft. Sampson was by her son's side when he was chosen by the Pelicans as the top player. “I wouldn't be here without my mom” said Zion with tears streaming down his face after his selection.

Zion was brilliant in the first 19 games of his regular-season NBA career, averaging over 23 points and six rebounds per game, before the coronavirus （冠状病毒）crisis forced the league to shut down. The 19-year-old Zion says he's been staying fit and will be ready to go when the league resumes.

American English began in the 17th century. At the beginning of the 17th century, the English language was brought to North America by colonists (殖民者) from England. They used the language spoken in England, that is, Elizabethan English, the language used by Shakespeare.

In order to find new resources in America, British colonists settled down there and from 1607 to 1732 set up thirteen colonies, including Virginia, North Carolina, New York, and New Jersey. In these thirteen areas, English was a common language used by all people. The first colonists established the English form in America.

As time went by, the English language gradually changed on both sides of the Atlantic. Foreigners longing for wealth set foot on the coastal area to trade. Americans borrowed many words from foreign languages and invented numerous new words to meet their commercial needs.

Following American Independence, famous people like Thomas Jefferson, the President, began to consider that the country should have a language of its own. Noah Webster compiled (编撰) three elementary books on English. Later, he expressed the idea that as an independent nation, America should have a system of its own in language as well as in government.

Since the rise of the United States to a position of world importance, American English has been developing and changing. There is no doubt that American English will enrich the English language greatly. With the rapid development of modem mass media and the common needs of economic, cultural and political exchanges, American English is more widely used in the world than British English.
