There are some differences between American English and British English. Some differences are quite interesting.

    When my friend Lily from London used the word “larder”, I didn't know what it meant. Realizing I didn't follow her, she used another word. I finally knew she wanted to find something to keep some food. The next word came up when we were planning a lunch date. She jotted down the date and time in her diary, while I marked my calendar. If she called me on the phone, she would ring me up. But if the line was busy, she would say the line was engaged.

    Most times, I can know what Lily means. Last week, she regretted sending her boys to watch an early morning tennis game without their fleeces. I thought that she meant without their jackets or something like those. Other times, we have to ask each other. She recently told me a funny tale about a woman who was pissed. I wondered what had made the lady angry. It turns out that pissed means drunk.

    Here is one more example. My British friend Jane was filling out a ticket at the grocery store recently. She asked the young man if he had a rubber. When she noticed he didn't follow her, she quickly asked for an eraser, which, in England, is often called a rubber.

    In order to communicate well with the British, we Americans should learn some words that the British use differently. And I think people who learn English as a second language should also realize that there are differences between American English and British English.

    Have you ever spent an afternoon in the backyard, maybe grilling or enjoying a basketball game, when suddenly you notice that everything goes quiet? There is an old phrase "calm before the storm"， often used in a situation—a quiet period just before a great activity or excitement. According to our own experience, we know there is actually calm before the storm. But what causes this calm? And is it always calm before the storm? Let's hear what scientists have to say.

    A period of calm happens in a particular kind of storm, the simplest kind of storm—a single－cell thunderstorm. In this type of thunderstorm, there is usually only one main updraft, which is warm, damp air and drawn from places near the ground. Storms need warm and damp air as fuel, so they typically draw that air in from surrounding environment. Storms can draw in the air that fit their need from all directions—even from the direction in which the storm is traveling.

    As the warm, damp air is pulled into a storm system, it leaves a low－pressure vacuum(真空) coming after. The rising air meets the cold dry air that has already existed in the storm clouds, thus the temperature of the warm, damp air drops, and the water vapour (水蒸汽) in it changes into tiny drops that are a precondition of rain. These drops accumulate and build on larger particles like dust, until they grow large enough to form raindrops.

    This warm, damp air keeps moving upwards, but it becomes cooler and drier during its trip through cloud. When it reaches the top of the cloud, the air gets spit out(被挤出) at the top. This air is sent rolling out over the big thunderclouds. From there, the air goes down. Warm and dry air is relatively stable, and once it covers a region, that air, in turn, causes the calm before a storm.

    Most thunderstorms, though, don't start with calm. That's because most are actually groups of storms with complex wind patterns. There's so much air moving up and down storm groups that the calm before the storm never happens. Instead, before the storm, it might be really windy!

    Brazil, the largest country in South America, is famous for the Amazon rainforest and soccer. But on the hottest days, people travel there for another reason – the Carnival. Full of excitement and fun, the Carnival is held annually in February or March. This year, the celebration runs from March 2^nd to 9^th.

    It is a wild festival of food, music and dance. The word "Carnival" comes from the Portuguese "Carne Vale", which means "farewell to meat". In the early 1600s, the Portuguese brought European traditions to Brazil. Then they started their own carnival with dances and music, which were inspired by black people brought there by the slave trade.

    With its beautiful floats (花车), attractive clothes and happy people, the Samba Parade is the most fantastic event of the Carnival. The Sambadrome is a special stadium for the Carnival in Rio de Janeiro with 80,000 seats where people can sit and enjoy the festival. Samba is said to be the soul of Rio. "This is where the passion for samba lies – the atmosphere is electric as even the oldest men and women sing and dance to the music," travel guidebook Lonely Planet noted.

    Top samba schools stand out in the main parade, with fantastic parades of floats and thousands of dancers. The parade goes on until dawn. The schools base their performances on certain themes from Brazilian history or on social and environmental problems, such as that of the Amazon rainforest.

    Besides fun street parties, colorful costumes and energetic music, Carnival also offers plenty of tasty street food, such as Quindim – a dessert made of egg yolks and sugar.

Overall, it is traditionally a time to go a bit crazy with eating, dancing and dressing up.

A Letter that Changed My Life

    I was about 30 years old and was working as a firefighter in the South Bronx's Engine Co. 82. It was a restful Sunday and between alarms I rushed to the office to read a copy of the New York Times. I read an article on the Book Review section which openly stated what I took to be a calumny – that William Butler Yeats had gone beyond his Irishness and was forever to be known as a universal poet. As I read it, my blood began to boil.

    There were few things I was more proud of than my Irish heritage, and ever since I first picked up a book of his poems from a shelf when I was in the military, Yeats had been my favorite Irish writer, followed by Sean O'Casey and James Joyce.

    I grabbed a piece of paper and wrote out a letter of anger to the editor. Throughout Yeats' poetry, his view of the world and the people in it was basically Irish. He had lived his life and written his poetry through the very essence of his Irish sensibility. It was offensive to think Irishness was something to be transcended(超越).

    I don't know why I felt it my duty to safeguard the reputation of the world's greatest poet. I just knew that I had to write that letter.

    After my letter got published, I received a letter from The New Yorker, asking for an interview. When my article Fireman Smith appeared in that magazine, the editor of a large publishing firm called me, asking if I was interested in writing a book about my life. I had little confidence to write a whole book, though the subject was worthy. I wrote Report From Engine Co. 82 in six months, and it sold really well. In the years that followed, I wrote three more best-sellers.

    Being a writer had been far from my expectations. How had it happened? I often found myself thinking about it, and my thoughts always came back to that letter to the New York Times. For me, the writing was a natural consequence of the passion I felt and the subjects represented the great values burning within me as I wrote.

    Over the years, my five children have come to me with one dilemma or another. My answer is always the same. Think about what you're feeling and measure the heat of the fire in your heart, for that is your passion. Your education and your experience will guide you toward making a right decision, but your passion will enable you to make a difference in whatever you do. That's what I learned the day I stood up for Ireland's greatest poet.

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. He and his wife had just parked around the corner from their own house in Allentown, Pennsylvania, when they got a call from one of his daughters, "The house next door is on fire!" He went to investigate. That's when he saw two women and a girl hysterical (歇斯底里的)on their porch.

    "The baby's in there!" one of the women cried. Though the fire department had been called, Surrell, then 64, instinctively ran inside. "The baby" was 8-year-old Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids, then 8, 10, and 12. The other two on the porch were Tiara's aunt and cousin.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been hazardous for anyone, but for Surrell, who has chronic obstructive pulmonary disease (慢性阻塞性肺疾病), they were life-threatening. He was the last person who should have run into a burning building— he has lung disease. But that didn't stop him.

    After a few minutes in the smoke filled house, he retreated outside to catch his breath. "Where is Tiara?" he asked desperately." The second floor." her aunt shouted back.

    Surrell knew he couldn't hold his breath for long. So he uttered a little prayer, "Well, Lord, this is it. You gotta help me, because I'm not coming out without that little girl." Taking a deep breath, he went in a second time.

    The darkness was overwhelming. Yet because the house had a similar layout to his, he found the stairs and made it to the second floor. He turned to the right and was met by intense heat. He was already out of breath.

    "Baby girl, where are you?" His throat and lungs burned as if he'd inhaled fire instead of the smoke and soot in the air. Every blink stung his eyes. All he could hear was the crackling and popping of burning wood. ①.Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. An ominous thought crossed his mind: I'm probably gonna die up here.

    Finally he touched something. A shoe, then an ankle. He pulled Tiara toward him. ②Her body was limp and she wasn't breathing. He scooped her into his arms and stood. He felt the heat of the flames on his cheeks. Turning, he fought through the smoke and ran blindly into the blackness. The next thing he knew, he was at the front door, then outside. Surrell put Tiara down on the porch.

    ③. A voice told him, "You have to breathe for her." He started CPR -the first time he'd ever done so. The women stood behind him, praying silently. Soon a soot-filled cough came from Tiara's throat. Surrell gave five more breaths. She coughed again. Her eyes flickered. He gave one final breath. She opened her eyes and took a breath on her own.

    ④.Their eyes met. Surrell hugged her tight and said, "Uncle's got you.^" Soon after, his throat closed off.

    Surrell woke up in the hospital a couple of days later, having suffered severe burns to his windpipe and the upper portion of his lungs. He spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire exacerbated Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. Wouldn't give it a second thought."
