People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.

    Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person's breathing muscles. Smokers usually take in small amounts that the body can quickly break down.

    Nicotine can make new smokers feel dizzy(头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers' risk of heart disease and stroke.

    Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.

    A new library in Tianjin—Tianjin Binhai Public Library—recently became an online hit. The Daily Mail described it as the “world's ultimate (终极的) library”, while the word “breathtaking” was the choice of Newsweek magazine. One look at the library and you'll see why. With its futuristic (未来主义) design and walls loaded with books, it's the dream library of every book lover.

    But as the surprise continues, there's a burning question lying in the back of our minds: When physical bookstores are closing down one by one, what makes libraries safe from the wave of digitalization (数码化)? And do we really still need libraries now that we've got the Internet in our hands?

    Reporter Ian Clark has the answer. “Libraries are not declining in importance—people are simply changing the way they use them,” he wrote on the Guardian website.

    What Clark means is that libraries have shifted from simply being storehouses of books to a medium to help “bridge the gap between the haves and the have-nots” according to website Libraries Are Essential. Since not everyone can afford a smartphone, a tablet or an Internet connection, and not everyone has the know-how to search the Internet correctly and efficiently, it's public libraries that make sure that these resources and technologies are available to a larger group of people.

    "Nobody is trying to sell you anything in the library. There is no pressure to buy and there is no judgment of your choices/' Anne Goulding, a professor at Victoria University in New Zealand, wrote on the Newsroom website. “There are few other spaces that you can just 'be' without somebody questioning your presence or your motivation."

    In the middle of the 19th century，a fever dream of riches beyond measure drew countless explorers west to the mountains of central California. Although the gold rush ended up being a bust for many who sought a fortune，some of those explorers discovered a natural treasure that would draw permanent settlers to Yosemite Valley in the following decade.

    Vast wilderness，beautiful mountains，countless waterfalls，and abundant wildlife drew Native Americans to Yosemite roughly 10，000 years ago. The first non-native tourists arrived in the mid-1850s after reports from gold seekers told of an area of breathtaking beauty that no words were able to describe.

    Fortunately，some of Yosemite's earliest settlers recognized that Yosemite's natural beauty and resources needed to be preserved for future generations. In the midst of the Civil War，President Abraham Lincoln signed a grant to protect Yosemite permanently，thus making it the nation's first land to be dedicated to recreation and setting the stage for what would become the national park system.

    One of Yosemite's earliest ambassadors was Scottish-American naturalist and writer John Muir. After living in Yosemite for a few years，he helped define its proposed boundaries. He also wrote articles that helped lead to its official title as a National Park in 1890.He later co-founded the Sierra Club in 1892 to advocate for its continued preservation and protection.

    Located on the western slope of the Sierra Nevada mountain range in central California，Yosemite National Park runs across nearly 748，000 acres，almost 95％of which is wilderness. Around four million visitors come to Yosemite each year to camp，hike its miles of trails，climb its rock formations，and photograph its impressive sights. Are you ready to visit Yosemite National Park? Which of Yosemite's sights would you most like to experience?

    Unlike most other holidays, the history of April Fools' Day, sometimes called All Fools' Day, is not totally clear. The only point in time that can be agreed on as the beginning of this tradition was 1582, in France. Before that year, the New Year was celebrated for eight days, beginning on March 25th. The celebration reached the highest point on April 1st. With the reform of the calendar under Charles IX，the Gregorian calendar(公历，阳历) was introduced, and New Year's Day was moved to January 1st.

    However, because in those days communications were not as developed as they are today, many people did not receive the news for several years. Some people refused to accept the new calendar and continued to celebrate the New Year on April 1st. These backward people were considered "fools" by other people. They  were often sent on "fools" errands(徒劳无益的工作)  or were made the targets of jokes.

    This developed, over time, into a tradition of playing a trick on someone on the first day of April. The tradition eventually spread to England and Scotland in the eighteenth century. It was later introduced to the American colonies of both the Britain and France. April Fools' Day thus developed into an international fun feast, so to speak, with different nationalities specializing in their own kind of humor at the expense of their friends and families.

    In a career that lasted more than half a century, Tom Wolfe wrote fiction and nonfiction best-sellers including The Electric Kool-Aid Acid Test and The Bonfire of the Vanities. Along the way, he created a new type of journalism and coined phrases that became part of the American vocabulary.

    Wolfe began working as a newspaper reporter, first for The Washington Post, then the New York Herald Tribune. He developed a literary style in nonfiction that became known as the "New Journalism." "I've always agreed on a theoretical level that the techniques for fiction and nonfiction are interchangeable," he said. "The things that work in nonfiction would work in fiction, and vice versa."

    "When Tom Wolfe's voice broke into the world of nonfiction, it was a time when a lot of writers, and a lot of artists in general, were turning inwards," says Lev Grossman, book critic for Time magazine. "Wolfe didn't do that. Wolfe turned outwards. He was a guy who was interested in other people." Wolfe was interested in how they thought, how they did things and how the things they did affected the world around them.

    In 1979, Wolfe published The Right Stuff, an account of the military test pilots who became America's first astronauts. Four years later, the book was adapted as a feature film. "The Right Stuff was the book for me," says Grossman. "It reminded me, in case I'd forgotten, that the world is an incredible place."

    In The Right Stuff, Wolfe popularized the phrase "pushing the envelope." In a New York magazine article, Wolfe described the 1970s as "The 'Me' Decade." Grossman says these phrases became part of the American idiom because they were accurate.

    "He was an enormously forceful observer, and he was not afraid of making strong claims about what was happening in reality," Grossman says. "He did it well and people heard him. And they repeated what he said because he was right." All those words started a revolution in nonfiction that is still going on.
