【题目】 The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger that other women by fighting free radicals. It made me curious about what free radicals ares.Is the anti-aging cream the only way I need to protect myself?

“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. Over time, oxidative stress weakens cell and tissues and can leave you more easily to certain health issues including cancer. And, as beauty marketers are keenly aware,oxidative stress can also speed up the aging process. Now that your know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.

【1】What does the author intend to do in paragraph 1?

这是一篇说明文。文章主要介绍了自由基是怎样形成的和自由基是怎样影响人的身体的。

【1】推理判断题。根据第一段The other day, I bought an expensive anti-aging cream that promised to make my face look several years younger that other women by fighting free radicals. It made me curious about what free radicals ares. Is the anti-aging cream the only way I need to protect myself?可知，前几天，我买了一款昂贵的抗衰老面霜，据说它能对抗自由基，让我的脸看起来比其他女性年轻好几岁。这让我好奇什么是自由基。抗衰老面霜是我唯一需要保护自己的方法吗？由此可推知，作者第一段讲述了她买了一个抗衰老的面霜来抵抗自由基给脸部留下岁月的痕迹的事，从而引出自由基的话题。故选C。

【2】细节理解题。根据第三段中Electrons (电子) are the negatively charged atoms, and they like to be in pairs.可知，电子是带负电荷的原子，它们喜欢成对出现。以及第四段中Bhuyan says, “Scientifically, free radicals are unpaired electrons that are seeking a mate to bond with.可知Bhuyan说：“从科学上讲，自由基是寻找配偶的未配对电子。”由此可知，自由基指的是不成对的电子。故选A。

【3】细节理解题。根据第四段中Another mini-science lesson for you: Antioxidants are natural or man made matters that can help delay or prevent some types of cell damage.可知，另一个小科学课：抗氧化剂是天然或人造物质，可以帮助延缓或防止某些类型的细胞损伤。由此可知，抗氧化剂可以减缓一些细胞的损伤。故选C。

【4】推理判断题。根据最后一段中Now that your know free radicals can weak on your health, you’re probably wondering if there are any ways to prevent them from forming or at least to minimize their negative effects.可知，既然你知道了自由基会损害你的健康，你可能想知道是否有办法阻止它们的形成，或者至少把它们的负面影响降到最低。由此可推知，作者接下来可能会围绕“自由基的形成是否能被阻止”展开。故选D。

【题目】 Ever since Zion Williamson was 5 years old, he wanted to be a basketball star. But to get there, he needed a lot of encouragement and coaching along the way, and there was no one that better than his mother, Sharonda Sampson. She coached Zion in every youth basketball league he ever played. Sampson was a collegiate track star and later became a middle school health and physical education teacher.

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.

【1】What do we know about Zion from the first two paragraphs?

【2】Why did Zion's mother ask him to watch three players?

A.She wanted to make Zion beat them one day.

B.She expected Zion to learn much from them.

C.She required Zion to join their basketball teams.

D.She wished Zion to like the same players as she.

【3】What did Zion mean by “I wouldn't be here without my mom”?

A.He would join the NBA with his mom

B.He would stand beside his mother firmly.

C.His success related to what his mom did.

D.He followed her wherever his mother went.

【4】What is the writer's purpose in writing the text?

【题目】 Some psychologists say that community art — art made to be displayed free of charge in a particular community — can make a big difference.

Unlike the random graffiti （涂鸦）that many people consider an eyesore, community art can bring people together and encourage respect. In the U.S. city of Philadelphia, for example, psychologists are doing a citywide project where mental health patients work with average people to paint murals（壁画）. The aim of this project is to reduce the mental illness and promote a new dialogue about people who struggle with these issues.

Art also makes neighborhoods more attractive and has a unique ability to open people up. Neighbors can share comments with one another about a recently painted mural, which can challenge their prejudices and open their eyes to the world.

Businesses can also be promoted by community art. In Fort Smith, a town in the U.S. state of Arkansas, artists from around the globe came together to paint murals. One of the goals of the project was to expand the town's cultural offerings in order to attract more visitors. Not only locals but also tourists were drawn to see the murals. The money they spent while visiting the town benefited local businesses.

Generous financial support is provided for community art projects in many cities and towns. In the UK, the Arts Council England has invested nearly half a million dollars in community art. Some of it, for example, has paid for a new exhibition space created inside an old mill in the town of Brierfield. In the U.S., an organization called the Knight Foundation has invested millions of dollars in community projects, including many that focus on art.

【1】What is the purpose of the community art project in Philadelphia?

A.To replace random graffiti.

B.To deal with the issues about mental illnesses.

C.To promote dialogues about art issues.

D.To encourage respect for psychologists and fine arts.

【2】How does community art open people up?

A.By changing people' s views on prejudices.

B.By giving new life to traditional murals.

C.By providing a subject for conversation.

D.By making neighborhoods more attractive.

【3】What does the text indicate about towns like Fort Smith?

A.They can profit from art economically.

B.They provide inexpensive courses in art.

C.They've placed some restrictions on art.

D.They borrow art from other communities.

【4】What do we know about the community art in the UK?

A.It is limited to rich communities.

B.It has the support of the government.

C.It started from a mill in Brierfield.

D.It is paid for by the Knight Foundation.
