2 . It was Mother’s Day and I was shopping at the local supermarket with my five-year-old son, Tenyson. As we were _______, we realized that only minutes earlier an _______ woman had fallen over at the entrance and hit her head on the ground. _______ was with her, but there was blood everywhere and the woman was embarrassed and clearly in shock. _______ a lot of people stopped to help out.

While we were walking towards the scene, Tenyson became very _______ about what had happened to the elderly couple. He _______ to me, “Mom, it’s not much fun falling over in front of _______.” Seeing that there was a flower stall (摊位) at the front of the supermarket, he added, “Why shouldn’t we _______ the lady a flower? It will make her feel better.” I was _______ that he’d come up with this wise idea. So we went over and told the flower seller ________ we wanted. “Just take it,” she replied. “I can’t take your money for such a wonderful ________.”

By now medical staff (医疗团队) had arrived, and were ________ the injured woman. We gave the flower to the woman’s husband and I told him it was ________ my son. At that, the old man started crying and said, “Thank you very much.” He then turned to me, “You have a ________ son. Happy Mother’s Day to you.”

The man bent down and gave his wife the flower, the old lady looked up at Tenyson with love in her eyes and gave him a little ________.

3 . In 2020, Nancy Ballard, a 60-year-old retired entrepreneur, went for a routine checkup at her doctor’s office that turned into something extraordinary. In fact, she was carrying a painting of a plant she’d done when she arrived there. “It would be great if we had _________ like that for our chemotherapy rooms (化疗室),” the nurse said. Ballard asked to see one.

She was shocked by _________ she found. The walls were grey and bare, and the paint was chipping. “_________, the patients here have nothing to look at while taking chemo drips,” she said, “I couldn’t imagine how anyone could even get healthy in such _________rooms like that.” She made it her mission to _________ the place.

She started by e-mailing 20 local interior _________. She wrote, “You don’t know me. But my heart _________ after seeing these rooms.” She then asked whether they would _________ their time and money to transform just one of chemotherapy rooms each.

Six of them leapt into _________ action and each designer chose a theme: The dragonfly room, for example, __________ bright artworks and dragonfly wall ornaments. Most rooms got new __________, lights, artworks, and furniture. When the transformation was done __________, Dr. Hufford was delighted. “All the patients feel __________ by it,” he said. He even noted that his own tone of voice was __________ in the rooms and that he was better able to connect with his patients. Ballard was so encouraged by the patients’ reactions, but when praised, she said, “What I did paled __________ the patients’ courage to fight cancer”.

5 . The bad health effects of sleep loss during the week can’t be repaid by longer weekend sleep, according to a new study.

Researchers have long known that sleep deprivation (剥夺) can cause weight gain and increase other health risks. But for those who force themselves out of bed every weekday after too few hours of shut eye, they hope turning off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.

The research, published in Current Biology, crushes those hopes. Despite complete freedom to sleep during a weekend recovery period, people in a sleep lab who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced disorders that would increase their risk for diabetes (糖尿病) over the long term. While weekend recovery sleep had some benefits after a single week of sleep loss, those gains were wiped out when people fell right back into their same sleep deprived schedule the next Monday.

“If there are benefits of catch-up sleep, they’re gone when you go back to your daily schedule. It’s very short lived”, said Kenneth Wright, director of the sleep and chronobiology lab at the University of Colorado at Boulder. “These health effects are long term. It’s kind of like smoking once was-people would smoke and wouldn’t see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think that sleep is in the early stage of where smoking used to be.”

Wright said that the study suggests people should put sleep in the first place cutting out the “sleep stealers” such as watching television shows or spending time on their phones. Even when people don’t have a choice about losing sleep because of child-care responsibilities or job schedules, they should think about getting sleep in the same way they would get a healthy diet or exercise.

7 . Final examinations were over, and some of my classmates and I got good grades. As a result, my classmates and I went to a fast food restaurant to celebrate it. We _________ hamburgers and Coca Cola at the counter. When our_________ came, I started walking towards an empty table. By bad luck, my purse strap (带子) got_________on a chair and the tray (托盘) that I was holding slipped_________my hands and went flying in the air. The tray, and its contents, _________ on a man who was just about to _________ a bite of his sandwich. I stared, greatly_________, as the drinks soaked (浸湿) his white shirt.

Then I_________ my eyes and prepared myself for his burst of _________. Instead, he said “It’s OK” to __________ me before he disappeared into washroom.

Still shaky and unsure __________to do next, my friends and I went to a table and sat there, trying our best to look__________. A moment later, the man came out of the washroom and__________ our table. My heart almost stopped__________. I though he was going to ask for my father’s__________ and call him.

To my surprise, he merely smiled at us, handed us some cash and said, “__________ yourself new hamburgers.” He then walked __________ without even finishing his food.

He could have made what was already an uncomfortable situation worse, __________ he chose a different way and gave us a reason to believe that there is still__________in this world. I’ll never__________ his actions.

8 . “I couldn’t move. I’ll have to wait here until you return.” I said to my friends. Both my feet ached so much and my______gave out under me. But at the last moment I______ with great strength and walked on with my friends till we climbed over the peak. This was what I had experienced 12 years before ________ I was climbing the Kirraki Mountain，and this______cheered me up. Compared to the journey to the Kirraki Mountain, climbing up the Wongsung Mountain seemed much easier. The only_____ was the snow.

On the 27th of January 2008, I went out alone, with the purpose of_____ the Wong sung Mountain. On my way I saw children playing merrily on the road, making snowmen and driving toy wooden trucks on the snow. Soon I ________ myself at the foot of the mountain. Looking up at the snow­covered giant mountain and seeing the steep slippery (滑) road with thick ice and snow, I suddenly felt a little_____, but the_____ of the footprints in the snow made me feel_____ that the top of the mountain was accessible. “You are not alone!” I tried to encourage myself._____ by a stick, I began moving forward slowly. In several places the road was so steep and slippery that I was on all fours and I almost____halfway. It was about 50 minutes before I got to the edge of of the mountain. But for the icy road, it would have been _______easy reach.

Seeing the white­covered pine trees, I couldn’t help entering the_______ In spite of the heavy_____, many trees were still standing straight, but some were bent down with snow and ice, some even fell and broke. Walking on the path in the forest, I could see no more footprints. Suddenly I sensed that it was_____ to walk in the woods in such dirty weather. In my childhood, I had witnessed thousands of trees, big or small, falling down one after another in a flash. ____that the falling of dominoes(多米诺骨牌) might happen, I hurried ____.

Now I’m sitting beside a warm stove, writing about my trip while my memory is still ____. This experience, though tiring and scary, is recognized as one of the most exciting moments in my life,_____ that I’ll value forever. It has again told me that nothing is impossible for a willing heart.

9 . As scientists around the world race to find a treatment for the coronavirus, a young girl among them stands out.

Anika Chebrolu, a 14­year­old from Frisco, Texas, has just won the 2020 3M Young Scientist Challenge ­­ and a $25,000 prize ­­ for a discovery that could provide a potential therapy to Covid­19 (or SARS­CoV­2 virus).

Anika's winning invention uses in­silico methodology to discover a lead molecule that can selectively bind to the spike protein of the SARS­CoV­2 virus.

"The last two days, I saw that there is a lot of media hype about my project since it involves the SARS­CoV­2 virus and it reflects our collective hopes to end this pandemic as I, like everyone else, wish that we go back to our normal lives soon," Anika told CNN.

The coronavirus has killed more than 1.1 million people globally since China reported its first case to the World Health Organization (WHO) in December. The United States has more than 219,000 deaths, according to data from the Johns Hopkins University Center for Systems Science and Engineering.

Anika, who is Indian American, submitted her project when she was in 8th grade ­­ but it wasn't always going to be focused on finding a cure for Covid­19. Initially, her goal was to use in­silico methods to identify a lead compound that could bind to a protein of the influenza virus.

"After spending so much time researching about pandemics, viruses and drug discovery, it was crazy to think that I was actually living through something like this," Anika said.

"Because of the immense severity of the Covid­19 pandemic and the drastic impact it had made on the world in such a short time, I, with the help of my mentor, changed directions to target the SARS­CoV­2 virus." Anika said she was inspired to find potential cures to viruses after learning about the 1918 flu pandemic and finding out how many people die every year in the United States despite annual vaccinations and anti­influenza drugs on the market.

10 . Basketball star Lebron James made ＄33 million last year. And that probably doesn’t surprise anyone. We’re used to watching professional athletes(运动员) make and spend millions of dollars.

But there was a time when professional athletes could barely buy a car. For most sports teams in 1950, there were main ways to make money. They sold tickets to games and popcorn in the stadium. For fans, it was a good deal(交易). You could see a Brooklyn Dodgers baseball game for 60 cents. For players, the deal wasn’t so great. There wasn't much money to go around. So salaries(薪水) stayed low. In some professional sports, players couldn’t spend the off-season working out. They had to get second jobs so they could pay the rent.

In the 1960s, television changed everything. In 1950, only 1 in 10 American homes had TVs. By 1960, 9 in 10 homes had TVs. And people loved watching sports. At first, team owners were worried about TV. They thought fans wouldn't pay to come to the stadium anymore. But the TV networks paid millions of dollars for the right to show games. That’s when sports teams started to get rich. Finally, the teams shared their wealth with players. In 1974, several baseball teams wanted a player named Catfish Hunter, who chose to play for the New York Yankees. They paid him ＄1 million just for picking their team. Since then, athletes have only gotten richer. In 2018, the highest-paid player in baseball will make ＄33 million. In basketball, the average salary is about ＄7 million a year.

Are sports stars worth the money? Many fans seem to think so. They will pay crazy prices to cheer for their favorite players.
