2 . Two weeks ago, a 5-year-old girl named Sunshine Oelfke emptied out her piggy bank (存钱罐) onto the living room floor and started counting. Her grandmother, Jackie Oelfke, thought she was playing as she carefully lined up the coins. But then she saw the girl put the coins in her backpack.

“What are you doing with that money?” Jackie asked her granddaughter.

“I’m taking it to school,” Sunshine replied. “I’m going to take it for milk money. My friend Layla doesn’t get milk—her mom doesn’t have milk money and I do.”

Jackie’s heart melted at Sunshine’s words. Choked (哽咽) with strong feelings, Jackie held her sweet granddaughter tightly in her arms.

Last week, Jackie and Sunshine met with her teacher, Rita Hausher, and handed her the $30 the girl had saved. There are 20 kids in Sunshine’s class and about half don’t get milk. It costs $ 0.45 a carton (纸盒). The total adds up to about $180 a month for every child in the class to have milk every day.

After dropping Sunshine off at school, Jackie posted a video on Facebook to explain her granddaughter’s plan. To her surprise, many people offered to donate toward the cause. Within a week, Jackie raised more than $1,000. Now every student in Sunshine`s class can get free milk for the rest of the year.

Jackie said Sunshine doesn’t see her kind act as a big deal. She was just trying to look out for her friends. “She doesn’t understand the influence she’s brought about,” Jackie said. “But now she knows she can do whatever she puts her heart to.”

3 . The first time you start to read a poem, you must relax and read through it without concentrating on its meaning. Imagine you are meeting a person for the first time. You will just observe him and listen to his voice, as well as watch his shapes or movements, but you have not yet known what he is all about. Likewise, you may enjoy the sound, rhythms, or wording, and form some first impressions about a poem.

On your second reading, you should concentrate more on the general meaning of the poem. This time, you will want to compare your feelings about the poem by now with how you felt before. Are they the same? What is different and why?

Your third reading will focus more on details: the words, phrases, or images. Looking up any unfamiliar words in a dictionary so that you can gain a more accurate understanding. Using the example given above about meeting someone, his image will change gradually and slightly as you meet and learn more about him. Therefore, in your additional readings, it is a good idea to compare your understanding each time with the understanding before.

A helpful approach to further understanding a poem is to summarize it in your own words. Compare your version of understanding with those of others reading the same poem, and listen to how they form such opinions. Remember, however, that there is no exact or right meaning for a poem, as most poets have admitted they themselves are not exactly sure what they meant when writing certain lines or phrases; they have even been heard to say on occasion that sometimes words just seem to “drop from heaven” and land on the page. That is what awakening the imagination is all about. If you are lucky, and if you practice enough, magical things may happen when you write and you may be able to produce a beautiful poem or other work of art yourself.

4 . I am sitting at the table in my favorite Boston bookstore-café, laptop open, writing. Ten minutes ago I ordered coffee. The server—a young, dark-haired woman with a broad smile and glasses—stopped and quietly said, “I just want to tell you how much your TED talk meant to me, you helped me find out what I really wanted to do with my life—go to medical school—and then you helped me do what I needed to do to get there. Thank you.”

Tears in my eyes, I asked, “What’s your name?”

“Fetaine,” she said. Then we talked for the next ten minutes about Fetaine’s challenges in the past and new-found excitement about her future.

Everyone who communicates with me is special and memorable, but this kind of communication happens far more often than I’d ever have expected: a stranger warmly greets me, shares a personal story about how they successfully dealt with difficulties, and then simply thanks me for my part in it. They are women and men, old and young, poor and wealthy. But something connects them: all have felt powerless in the face of great pressure and anxiety(焦虑), and all discovered a quite simple way to free themselves from that feeling of powerlessness.

For most writers, the book comes first, then the responses. For me, it was the other way around. First, I performed experiments that led to a talk I gave at the TEDGlobal conference in 2012. In that talk, I discussed some interesting findings about how we can quickly increase our confidence and decrease(减轻) our anxiety in challenging situations. I also shared my own troubles and how I learned to become more confident. Soon after the twenty-one-minute video of the talk was posted on the Internet, I began hearing from people who had seen it.

Of course, watching my talk didn’t magically give Fetaine the knowledge she needed to do well on Medical College Admission Test. But it may have helped her get out of the fear that could have prevented her from expressing the things she knew.

5 . Endangered polar bears are breeding (繁殖) with grizzly bears (灰熊), creating “pizzly” bears, which is being driven by climate change, scientists say.

As the world warms and Arctic sea ice thins, starving polar bears are being forced ever further south, where they meet grizzlies, whose ranges are expanding northwards. And with that growing contact between the two come increasing hybrids (杂交种).

With characteristics that could give the hybrids an advantage in warming northern habitats, some scientists guess that they could be here to stay. “Usually, hybrids aren’t better suited to their environments than their parents, but these hybrids are able to search for a broader range of food sources,” Larisa DeSantis, an associate professor of biological sciences at Vanderbilt University, told Live Science.

The rise of “pizzly” bears appears with polar bears’ decline: their numbers are estimated to decrease by more than 30% in the next 30 years. This sudden fall is linked partly to “pizzly” bears taking up polar bears’ ranges, where they outcompete them, but also to polar bears’ highly specialized diets.

“Polar bears mainly consumed soft foods even during the Medieval Warm Period, a previous period of rapid warming,” DeSantis said, referring to fat meals such as seals. “Although all of these starving polar bears are trying to find alternative food sources, like seabird eggs, it could be a tipping point for their survival.” Actually, the calories they gain from these sources do not balance out those they burn from searching for them. This could result in a habitat ready for the hybrids to move in and take over, leading to a loss in biodiversity if polar bears are replaced.

“We’re having massive impacts with climate change on species,” DeSantis said. “The polar bear is telling us how bad things are. In some sense, “pizzly” bears could be a sad but necessary compromise given current warming trends.”

6 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.

For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.

Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”

Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

9 . Was it probable that Tang Dynasty poet Li Bai and Western hero King Arthur meet and fight against each other? Yes. In a game called King of Glory, created by Chinese company Tencent, King of Glory has been one of the most popular MOBA games in China since 2017.

About one in every seven Chinese people plays the game, and 55 million of them play it every day. The game is easy for beginners. Social media like QQ and WeChat have also helped the game’s community grow. New players can be invited to play the game by their WeChat contacts, with some seeing it as a good way to keep in touch with old friends and make new ones.

The game has more than 60 characters to unlock and play as you progress, each with their own special styles and abilities. The characters cover different times and countries. Some are real historical characters, like Li Bai. Some are not. Players use them to fight against each other or team up to fight. The winners can reach higher ranks.

However, some people think King of Glory gives the students incorrect information about events and people in history. For example, the poet Li Bai is described as a killer; Jing Ke, the man who tried to kill the first emperor of China, is a girl in the game. But more people worry about children playing the game too much and spending too much money on it. Most of the players are below the age of 19. It’s reported that a 17-year-old boy had a stroke (中风) after playing the game for 40 hours.

To change the situation, Tencent added a time limit feature to the game to prevent kids from playing too much. From 4 July 2017, children under 12 years old can play the game for only one hour a day, while users between 12 and 18 get two hours. Those who try to play beyond the time limit will be locked out of the game.

10 . Jonathan Jones, 12, was overcome with emotion after his principal, who is also color-blind, let him _______ his unique glasses during science class last week.

As soon as Jones put the glasses on, he appeared to be immediately _______ . He initially smiled and laughed, _______ he broke down moments later. He then walked around the classroom excitedly, _______ the now-vivid colors around him.

“I was feeling joy that I could _______ see all this color, and a little bit of _______ that I couldn’t see color my whole life,” Jonathan told ABC news.

The boy’s mother posted a(n) _______ of Jonathan seeing color for the first time online and started a GoFundMe campaign to buy a pair of the unique glasses for Jonathan, which reportedly cost $350. However, so many people were _______ by Jonathan’s story, and the campaign actually ended up _______ more than $25,000.

She wrote: “After posting the video we’ve been touched by how many ________ people have wanted to help him. We’ve had multiple pairs donated to Jonathan and will use 100% of ________ funds to purchase color-blind glasses for those who can’t ________ them.” “The glasses company will match every pair we purchase with a free pair, which ________ the number of people we can ________ ,” she continued.

For Jonathan, with the new glasses comes a new ________ of the world. He said his favorite color is blue and he’s excited to visit the Caribbean this winter so he can see the ocean in all its glory.
