I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签 ) everything. I always looked for everything. Over time, Kate got nearer and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

    War broke out one evening. Kate came into the room. Soon, I heard her screaming, "Take your shoes away! Why under my bed!" Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

    The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬) under her covers, sobbing.

    Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me. "Thanks."

    Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to living together: giving in cleaning up and holding on.

       Although I started learning English during my college years, when I entered the States, I only understood two English words “Yes” and “No”. We learned many grammar rules but we could not make the language connections to the real English world. Language frustration worries almost all first generation immigrants. For example, I got a letter from a Chinese-American who has lived in the States for a long time and has a good IT job saying “My 11-year-old girl writes quite well, but as her parents, we could not even read her article.”In addition, my Chinese-American professor friend has difficulty reading a novel. Improving our English skills has become a long journey for all of us. Honestly, if I have a chance, I really want to reach out to everyone in the world who has had a similar experience: learning a second language in adulthood. I wish I could encourage them to speak out about the culture shock, frustration they felt about the differences between West and East.

     I have mainly focused on my English writing since 2008 after I found “Literacy Volunteers”, an organization that specially focuses on helping immigrants improve their English. I decided to challenge myself, writing a story like an American. I saw many wonderful Americans there. As soon as I met my teacher Alice, I asked her to be my private language tutor and have taken Tims English class. Every week Alice and I have worked on my English essays sentence by sentence.

     To observe the culture differences between West and East, occasionally, I posted a few of my English essays online. I mentioned previously about American culture; when people read the same article or even face the same situation, American and Chinese act very differently. In my viewpoint, these differences make America the strongest country in the world. I know you have the right to express your own opinions, but accusing others without proof is not acceptable.

    The associates I hired in my bicycle and lawn mower shop like myself were never perfect; however, they were excellent. Working with them as they improved taught me new ways to show forgiveness, understanding, and patience.

    One day the placement officer asked me to interview a young man who was having trouble finding a job. He told me that David was a little shy, did not talk much and was afraid to go on with interviews. He requested that I give David an interview just for practice. He plainly told David that I had no positions open at the time and the interview was just for practice.

    When David came in for the interview, he hardly said a word. I told him what we did at the bicycle shop and showed him around. I told David to keep showing up because the number one thing an employer wanted in an associate was dependability. David was very quiet (he was evaluated as a slow learner in school).Every ten days or so, for weeks after the interview, David walked into the bicycle shop and stood by the front door. He never said a word, just stood by the door.

    One day, shortly before Christmas, a large truck came to the shop, packed with 250 new bicycles. It had to be unloaded right away or the driver would leave. It was raining. Some of my workers (without physical limitations) chose not to brave the weather to get into work, so I was short-handed. It seemed everything was going wrong and on top of it, David came in the front door and just stood there. I looked at him and shouted,“Well, all right! Fill out a time card and help me unload this truck!”

    David worked for my bicycle shop for eighteen years. He came to work every day thirty minutes early. He could talk; however, he rarely chose to. He drove my truck and made deliveries. The customers would praise David, saying,“He doesn't talk, but he really shows you how to operate a lawn mower!”

    My first term at MIT（麻省理工学院）was awesome—I got all A's, and I declared math as my major. My parents were expecting me to become a doctor like them so I was trying to satisfy them. But I was desperately running away from them. I had no idea what I wanted to do with my life. My third term, I ended up with a D in math. I didn't do that well in my other classes, either. It seemed like all my friends were doing so well, getting opportunities over the summers.

    My fifth term, I realized that I was awful at higher-level math. I had lost all confidence in myself. I went to a few classes at the beginning of the term, but after by midterm, I had totally stopped. My only relief was the dance team I was on. I would sleep all day, and then go to dance practice, and then go back to sleep. As expected, I failed in all of my classes and had to withdraw from MIT.

    I had no choice but to tell my parents. Instead of yelling or hitting me, though, they just held me and cried. The next day, my dad took a day off from work and took me to a nearby, small arts college.

    I had lost all confidence in myself. Before my first biology test, I didn't think I could pass. I did pass. Since I had so much free time, I decided to join a biology lab. I realized that was what I wanted to do! I wanted to be a scientist!

    This past May, I graduated with the highest honors, and now I have my PhD in biology. Though it ended up taking me 5 years to graduate from college, I can say now that dropping out of MIT was one of the best things that ever happened to me. I've realized that a person is not their grades. I've realized how much my parents loved me. I've finally discovered my passion（热情）in life!

    Did you know that Albert Einstein could not speak until he was four years old, and could not read until he was seven? His parents and teachers worried about his mental ability.

    Beethoven's music teacher said about him, "As a composer (作曲家) he is hopeless." What if this young boy had believed it?

    When Thomas Edison was a young boy, his teachers said he was so stupid that he could never learn anything. He once said, "I remember I used to never be able to get along at school. I was always at the foot of my class ... My father thought I was stupid, and I almost decided that I was a stupid person." What if young Thomas had believed what they said about him?

    When the sculptor (雕刻家) Auguste Rodin was young, he had difficulty learning to read and write. Today, we may say he had a learning disability. His father said of him, "I have an idiot (白痴) for a son." His uncle agreed. "He's uneducable," he said. What if Rodin had doubted his ability?

    Walt Disney was once fired by a newspaper editor because he was thought to have no "good ideas". Enrico Caruso was told by one music teacher, "You can't sing. You have no voice at all." And an editor told Louisa May Alcott that she was unable to write anything that would have popular appeal.

    What if these people had listened and become discouraged? Where would our world be without the music of Beethoven, the art of Rodin or the ideas of Albert Einstein and Walt Disney? As Oscar Levant once said, "It's not what you are but what you don't become that hurts."

    You have great potential. When you believe in all you can be, rather than all you cannot become, you will find your place on earth.

It's 1:30 am in Kenya's populated north, and 50 people are lying on their backs on the shore of a dried-up river, staring up at the night sky. These stargazers have travelled 250 miles to Samburu to witness the Perseid meteor shower(英仙座流星雨). They are not disappointed: Every few minutes, arrows of light shoot across the sky like silent fireworks.

The Star Safari is organised by a Kenyan astronomer, Susan Murabana, who has brought a 50 kg,170 cm-long telescope to allow the group to view Mars and deep-sky objects. But here in Samburu, where light pollution is minimal, the Perseid meteors—visible with the naked eye (裸眼)—steal the show.

Every two months, Murabana and her husband load their telescope on to the roof of their 4×4 and set off to rural communities, where they give up to 300 children a chance to view the planets and learn about constellations (星座) and the basics of astrophysics. They primarily targets schools in remote areas because of her mission to give girls an opportunity that she wishes had been available to her.

"When I started this work, I didn't see people who looked like me. I was a lone ranger and I wanted to change that." says Murabana.

"There is a common misconception in Kenya that astronomy in general is hard, boring, and only for boys," she adds. "I'd like to teach young girls that astronomy is neither of these things and that they, too, can become astronomers," says Murabana.

Murabana's passion for astronomy began in her early 20s when her uncle invited her to join a similar outreach session organized by the Cosmos Education. "That was a gamechanger. If an outreach group had come to me when I was a young teenager, my attitude towards a career in astronomy would have been positive. I ended up studying sociology and economics, but maybe I would have desired to be an astronomer," she says.

Inspired by the Cosmos Education, Murabana completed an online master's degree in astronomy with the James Cook University in 201l and set up her own outreach programme. She looked to Dr Mae Jemison, the first black woman in space, as a role model. "I hope that one day, through this work, I will spark a chain reaction that leads to the first African woman in space."
