On paper, hydrogen (H2) looks like a dream fuel. Coal, oil, and natural gas produce carbon dioxide, which warms the earth when burned, Hydrogen produces pure water. Hydrogen packs more energy into less space than a battery (but certainly less than petrol) . Also, empty tanks (燃料箱) can be refilled with hydrogen much faster than refilling empty batteries with electricity.

While in practice, things are trickier. Storing a meaningful amount of hydrogen gas requires pressing it several hundred-fold. Changing it into the liquid form is another option, but it should be cooled to-253C. Both processes require a heavy and strong tank. While a 700 bar tank is acceptable for a city bus or a truck, adapting it for use in small vehicles is very difficult because the pressure during refilling would be too great.

The solution? Powerpaste.

A German team of researchers, led by Marcus Vogt, have come up with an interesting "powerpaste", which can store hydrogen energy at atmospheric pressure, ready for release when needed. It is so named because it comes in tubes and looks like toothpaste (牙膏) , not in its traditional form of gas.

The main ingredient (原料) of the paste is magnesium hydride, a substance that reacts with water to form hydrogen. The escaped hydrogen can then be directed into a fuel cell, where it reacts with oxygen from the air to produce electric power.

Refueling is very simple, as instead of going to a filling station, drivers and riders can simply replace an empty tube with a new one and refill the water tank.

Given that powerpaste only begins to break down at temperatures of around 250℃ it remains safe even when a vehicle stands in the baking sun for hours.

However, we will have to be patient. Just because researchers have succeeded in developing a new fueling way does not mean that we can expect to see such vehicles on the road anytime soon. It will indeed be several years before this concept is turned into reality.

(1)、As a fuel, what is the advantage of hydrogen over oil?
A、Refilling empty tanks will be more convenient. B、It is less likely to worsen global warming C、More energy can be packed in the same space. D、It will produce pure water for people to drink.
(2)、What is Paragraph 2 mainly about?
A、The practical difficulties to use hydrogen as fuel in small vehicles. B、The detailed processes of adapting a strong tank in small vehicles. C、The differences in fueling between large vehicles and small ones. D、The tricks of building strong tanks in small vehicles.
(3)、The author mentions the refueling process to show that powerpaste is______________.
A、inexpensive B、powerful C、convenient D、environment-friendly
(4)、Why does the author call on the readers to be patient?
A、Powerpaste-driven vehicles sometimes move very slowly on the road. B、Practical use of powerpaste-driven vehicles will not come very soon. C、Powerpaste-driven vehicles can only work after being in the sun for hours D、It will be years before the researchers work out the concept of powerpaste.

    A few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations(语调)of the driver's accent washed over me in a familiar way.

    I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That's how he found out I go to Harvard. An approving eye glinted at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up — the product of his sacrifice.

And then came the fateful question: "What do you study?" I answered "history and literature" and the pride in his voice faded, as I knew it might. I didn't even get to add "and African-American studies" before he cut in, his voice thick with disappointment, "All that work to get into Harvard, and you study history?"

    Here I was, his daughter, squandering the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous) — to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative(故事)of upward mobility so your children can do the same.

I used to feel anxious and backed into a corner by the questioning, but now as a junior in college, I'm grateful for their support more than anything. This holiday season, I've promised myself I won't huff and get annoyed at their inquiries. I won't defensively respond with "but I plan to go to law school!" when I get unrequested advice. I'll just smile and nod, and enjoy the warmth of the occasion.

    I decided to ski to the North Pole. It was after I saw an advertisement in a newspaper looking for people to join a team to ski 350 miles to the North Pole. Back in 1996, there had never been a woman from the UK who had accomplished this challenge. I wondered what it would be like to survive in temperatures cold enough to freeze your flesh in seconds, so I sent off for the application form.

    The application form full of pictures of male explores arrived. The words "Are you man enough for the ultimate(极限的)challenge?" made me angry and even more determined to get on the team.

    Over 500 individuals applied for a place in the team, and the selection process included physical and psychological tests designed to pick the best group. In one test, there was a huge rope ladder we had to climb, and I froze at the top because I have a fear of heights. I thought my hopes were fading as most other applicants sailed past, leaving me behind. But two others helped me over, and later I found out that the organizers were not looking for amazing individuals, but great team players, and this moment had shown them who would take care of others in the team.

    I had revealed(显示)my weakness, and in a place like the Arctic, you have to be yourself, as there is nowhere to hide. These personalities of asking for help and showing weakness are necessary for women to master.

    I realized that by being myself, I could succeed. I was selected for the team. I realized that I could achieve more than I ever imagined — more importantly, by sharing my story with others, I could inspire them to take a step into the new world and reveal more of their abilities.

    While many Chinese watched movies at cinemas during the weeklong Spring Festival holiday, Zheng Wei explained the film The Spring Festival to an audience of visually impaired(受损伤的) people at cinema in Northern China's Tianjin.

    "Fireworks light up the dark on New Year's Eve, and children are playing in an open place covered with white snow, said Zheng to the audience, describing the visual elements of the movie while holding a micro-phone and a script.

    As the founder of "cinema for the blind" in Tianjin, the 55-year--old has insisted on brightening the dark world of the visually impaired in his own way for 11 years.

    Shao Yuxiang and her husband, who are both blind, are regular visitors of the cinema. She wore an elegant yellow sweater to attend the couple's significant "movie day".

    Since October 2007, the free movies, which are described through audio, start at 9: 30 am on the third Saturday of each month. More than 150 movies have been screened to more than 20,000 visually impaired.

    "The theater is equipped with lights a sound system, projector, and a big screen to give the blind a people so far complete and equal movie experience," Zheng said.

    In 2007, after having learned that a "cinema for the blind" established by Wang Weili had benefited many visually impaired people in Beijing, Zheng rushed to Wang's establishment for advice. Under Wang's guidance, Zheng built a new cinema in Tianjin and screened The Dream Factory by Chinese director Feng Xi-aogang. It attracted more than 50 visually impaired people from different districts and even suburban areas in Tianjin.

    Zheng always treats movie selections with seriousness He usually chooses Mandarin language movies with positive themes that reflect modern society. Special movies for certain Chinese festivals are also part of Zheng's selection criteria. "For example, The Founding of Republic is specially for National Day. Now, films for Spring Festival are on my agenda," Zheng said.

    I particularly enjoy the works of Greenwich Village poet Edward Field, whose interest in cinema led to a number of poems based on old monster movies (including many about Frankenstein and my favorite, Curse of the Cat Woman).

    There are so many to choose from! I love Robert Frost, especially "Mending Wall", mostly because he is my dad's favorite poet. However, personally I love Lnagston Hughes's poem "Dreams" because it always brings happiness to me. I am also a big fan of the older poems, such as Spenser's "One Day I Wrote Her Name Upon the Strand" because it is so simple, and "The Tyger" and "The Lamb" by William Blake because I love the language.

    My favorite poet is Suji Kwock Kim. Ever since I read her book of poetry "Notes from the Divided Country", I have been a big fan of her clear and thoughtful writing. My favorite poem of hers is "Borderlands", which she wrote in memory of her grandmother. It is a poem about her grandmother's experiences during the war.

    Hard to decide! But if I have to, I'd say Emily Dickinson. Her life was so wonderful and her opinions about life are also interesting. Her understanding of nature speaks to the heart of anyone who loves the outdoors! Dickinson also understood human nature very well. Her poems speak of love, loneliness, ect. Finally, my favorite poem by her is "I Never Saw a Moor". I love her thoughts!

15 years ago, Erin Merryn met a kitten who needed a home when she was a college student.

He jumped into her arms and refused to let her go.

"I was attached immediately and decided that I would take a risk and try hiding a kitten in my college dorm where animals are obviously not allowed," Erin recalled.

A week later she was caught and given 48 hours to remove the cat. After several phone calls, Erin was able to find an old lady to take Bailey, the kitten. But Bailey did not get along with his new housemate. As soon as Erin learned that he would be sent away, she immediately offered to take him back. "I plotted for a month to convince my parents to let me keep him." said Erin.

Six years ago, Erin had Abby, her beautiful daughter. She didn't know what Bailey would think about the new addition when she brought her home from the hospital.

"But it was love at first sight." Erin said. Bailey stayed by Abby's side, guarding and showering her with love and purrs. As Abby grew, he became her protective brother, watching over her every step of the way. Abby picked up a book one day and tried to read it with Bailey by her side. He became her perfect audience, and the sweet boy was completely attracted by Abby as she told him stories of wonder.

A video showing Abby reading to Bailey went viral on the Internet in 2018. Numerous people followed Erin on social media platforms.

Unfortunately, on December 8, 2018, just months after becoming famous, the 14-year old cat passed away from kidney failure.

A full month after Bailey's passing, Erin still got cards and gifts from caring individuals. It is this love that Erin hopes Bailey's fans hold on to. She wants her furry "first-born" to be remembered as a symbol of compassion that inspires others to treat the world with love.
