Are you interested in travelling? Here are famous national parks where travellers mostly like to go in America.

    ⒈Great Smoky Mountains National Park

    Visitors: 11,388,893

    The name "Great Smoky Mountains" comes from the fog over this mountain range situated along the North Carolina-Tennessee border. Established in 1934, it is not just home to a diverse ecosystem of plants and animals, but also home to rich Appalachian cultures. Visitors there can see over 100 waterfalls, go boating on Fontana Lake and hike the Appalachian Trail. It's also an excellent vantage point to see the leaves change in the fall.

    ⒉Grand Canyon National Park

    Visitors: 6,254,238

    The Grand Canyon is the result of over 70 million years of geological events creating the Colorado Plateau, glaciers and valleys, while the Colorado River carved its way through the valleys. It is truly a natural splendor!

    When President Roosevelt first visited it in 1903, he said, "The Grand Canyon fills me with awe. It is beyond comparison – beyond description."16 years later, it was signed by President Woodrow Wilson, officially viewing the Grand Canyon a national park.

    ⒊Yosemite National Park

    Visitors: 4,336,890

    In addition to being a national park, Yosemite is designated as a World Heritage Site. Yosemite National Park is in Central California in the western Sierra Nevada. Though it covers around 1,168 square miles of area, visitors spend most of their time in the 5.9 square-mile area of the Yosemite Valley where there are some most famous sites like Yosemite Falls, and Cook's Meadow Loop.

    ⒋Zion National Park

    Visitors: 4,504,812

    Settled in Southwestern Utah is Zion National Park. It has some of the most unique landscapes packed with mountains, valleys, rivers, desert and forests.

    Zion National Park is also an important place to study ancient humans who made the area their home about 8,000 years ago. Some of the park's most notable attractions include Angel's Landing, Kolob Arch, the Narrows, etc.

    I remember little of the journey which started so early in the morning. I only know that the day seemed extremely long, and that we appeared to travel over hundreds of miles. Calmed by the sound of the coach wheels, I fell asleep. But I had not slept long when the coach stopped, the door was opened, and I saw a servant standing there.

    "Is there a little girl called Jane Eyre here?" she asked. I answered "Yes," and was then lifted out. My trunk handed down, the coach instantly drove away. I looked about me. I could see a house with many windows. There were lights burning in some of them. We went up a wide pebbly path, splashing wet, and were admitted at a door. Then the servant led me through a passage into a room where she left me. I stood and warmed my frozen fingers at the fire and looked around. There was no candle, but the light from the fire showed papered walls, a carpet, curtains and gleaming furniture. Then the door opened, and a tall lady with dark hair, dark eyes entered followed by another who looked younger. "The child is very young to be sent alone," said she, putting her candle down on the table. She looked at me for a minute or two and then added, "She had better go to bed soon; she looks tired."

    Led by the younger lady, Miss Miller, through passage after passage, we came, at last, to a long, wide room filled with the hum of many voices. There were many tables, and seated all round on benches were a large number of girls aged from nine to twenty. Seen in the dim light of the candles, their number appeared above eighty. Each was dressed in a brown old-fashioned dress of cheap material. It was their hour of study.

    Miss Miller signed to me to sit on a bench near the door, then walking up to the top of the long room she cried out "Monitors, collect the lesson-books and put them away!"

    Four tall girls arose and went round, gathered the books and removed them. Miss Miller again ordered, "Monitors, fetch the supper-trays!" The tall girls went out and returned presently, each bearing a tray. Some food and water was in the middle of each tray. The food was handed round and everyone drank from the same mug. When it came to my turn, I drank too, for I was thirsty, but I did not touch the food. From there I was taken to my hard bed where I thankfully fell asleep immediately.

When we meet someone for the first time, we usually get a vague sense of what kind of person they are by the way they shake hands, talk, or walk. In the age of social networking, however, first impressions are sometimes made even before we actually meet someone in person—that is, by looking at their profile photo.

    According to a recent study, these social images say a lot about our personality. In the study, presented in a paper at the International AAAI Conference on Web and Social Media, a group of researchers from the University of Pennsylvania in the US used software to analyze the profile pictures of 66,000 users of US social platform Twitter and 3,200 of their tweets. At the same time, about 434 participants were asked to complete a survey about their personality type. The researchers wanted to find out if there was a connection between personality traits—like openness, extroversion, and neuroticism(神经质)—and a person's profile picture.

    According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences. Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；Instead, they use an image of something like a pet, a car or a building.

    Apart from the objects in profile pictures, the colors used in them also give us some hints about the photo's owner. For example, extraverts were found to have the most colorful profile images, as they want to emphasize their personality and show themselves off, the researchers wrote.

    Although social media photos "usually represent an extension of one's self, they also allow a user to shape his or her own personality and idealized view," according to the researchers. So, when choosing a profile photo, maybe we should ask ourselves first what kind of image we'd like to convey. After all, first impressions always last.

    Janus, the Roman god, has two faces looking in opposite directions. So does artificial intelligence (AI). On one side are the positive changes, enabling people to achieve more, far more quickly, by using technology to improve their existing skills. Look the other way, though, and there are plenty of potential pitfalls.

    Like Janus, technological change may also cause disruption(混乱), but AI is likely to have a bigger impact than anything since the appearance of computers, and its consequences could be far more disruptive.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although CEOs publicly praise the broad benefits AI will bring, their main interest lies in cutting costs. One European bank asked Infosys to find a way of reducing the staff in its operations department from 50,000 to 500. The McKinsey Global Institute estimates that by 2030 up to 375m people, or 14% of the global workforce, could have their jobs replaced by AI.

    A second important question is how to protect privacy as AI spreads. The internet has already made it possible to track people's digital behavior in minute detail. AI will offer even better tools for businesses to monitor consumers and employees, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised service or promotions. But AI is bound to bring invasion of privacy that is seen as unacceptable. For example, law-enforcement officials around the world will use AI to spot criminals, but may also monitor ordinary citizens.

    The third question is about the effect of AI on competition in business. A technology company that achieves a major breakthrough in artificial intelligence could race ahead of rivals, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

    It is too early to tell whether the positive changes brought by AI will outweigh the risk. But it will put an end to traditional ways of doing things and start a new era for business and for the world at large.

Some Myths You Strongly Keep Believing Are Untrue

    There are varieties of false myths we spread from day to day.. Otherwise, people will continue to believe such ridiculous myths undoubtedly. You will realize some of the most acceptable facts are completely untrue.

    Men get beer bellies from beer.

    We blame the beer for the belly. It is widely believed that men who constantly drink beer end up with a beer belly. However, it is not the beer that's to blame, but the abundance of unhealthy snacks that often accompany the drink. Alcohol in beer irritates the stomach, therefore causing an increased appetite. Dr. Michael Jensen, an obesity specialist in Minnesota USA says that drinking beer makes liver burn alcohol instead of fat, leaving the latter to accumulate in the waist., while the one of women's accumulates in the hips and  bottoms, as a result of different sexual characteristics.

    .

    We are told that dogs see the world in black and white. But the truth is that they can distinguish colors just not in the same way we do. Jay Needs from the University of Washington in Seattle proves that our furry friends are able to receive a limited range of colors, which means they can distinguish objects of the same shape. In general, a dog's vision is very similar to that of a person with red-green color blindness.

    Carrots improve eyesight.

    . This myth came into existence during the Second World War. The British Army claimed that fighter pilots had excellent night vision as a result of their consumption of large quantities of carrots. Actually, they had radars onboard which made it faster and easier to detect the enemies. The myth about the amazing power of carrots was invented and spread by the media so that enemies would not learn about the fact..

A. Dogs can distinguish colors

B. Men's fat is stored in their bellies

C. Dogs see the world in black and white

D. Men's fat is not mostly accumulated in these parts

E. Eventually, it spread all over the world and people are still convinced of it

F. We agree with the view that eating carrots plays an essential part in good vision

G. It is high time that scientists created a separate department dedicated to exposing the truth

    I am an amateur radio operator. A few weeks ago, I was heading towards the basement with a steaming cup of coffee in my hand. What began as a1 Saturday morning,2 one of those lessons that life seems to hand you occasionally.

    When I turned up my radio for a Saturday morning swap net, I 3  an older man with a4signal and golden voice. He was telling5 he was talking with something about "a thousand marbles"

    "It sounds like you are busy with your job. Surely they pay you well but it's a6 you have to be away from home. You missed your daughter's dance recital. You see, the7 person lives about seven-five years. Now I8 75 times 52 and I came up with 3,900, which is the number of9 that the average person has in their entire lifetime. It took me until I was fifty-five years old to think about this10", he went on "and by that time I have 11 2,800 Saturdays. If I lived to be seventy-five, I only had about a thousand left to enjoy. So I went to stores to round up 1000 marbles. I put them inside a12container. Every Saturday since then, I have taken one marble out and thrown it away."

    "I found by watching the marbles13, I focused more on the really important things in life. There is nothing like watching your time run out to help get your14 straight. This morning, I took the very last marble, I think if I 15 it until next Saturday then I have been given a little extra time by life. Time is the only thing we can use in life. Bye, and I hope you can spend more time with your16" and then he17.

    I guess he gave us all a lot to think about. I had planned to work that morning, and then I was going to 18 a few friends to work on the next club newsletter.19 , I20 and woke my wife up and decided to take her and the kids to breakfast.

    When it comes to climate change, language does count. In March, the Guardian changed(it) wording – using "global heating" instead of "global warming" , after scientists found that Earth's temperature is set (rise) from between 2.5C and 4.5C. And on May 1, the UK parliament declared a "climate emergency", (become)the first parliament to do so.

    If with "global warming", we're still inside our comfort zone of handling the situation, entering the state of "global heating" is like heading to a point the delicate balance of nature is disturbed so much that there is no turning back. Everything will be changing: Coral will die, polar bears will lose their habitats completely, and extreme (weather) like droughts and heavy storms will happen at a higher (frequent). There is no denying that we're entering a climate emergency.

    Decades ago when the science on the climate issue was first increasing, the impacts could be seen as an issue for future generations," but now it's (definite) our issue, shift we all are living together.

    However, getting these messages is far from enough. It depends on each to find a solution – if there are any solutions left to find. The UK's Labor leader Jeremy urged that "we (take) rapid and dramatic action now".

    Indeed, language matters. But action matters even more.

Dear Tom,

    How have you been recently？Though everything is going good here, but I still want to get some help from you.

    I'm going to participate the Chinese Character Hero competition, which is aimed at giving teenagers a opportunity to show their level of Chinese characters. I attached great importance to this competition, but I'm quite nervously. I know you have won in many competitions ago and have much experiences in how to adjust the state of mind. I hope what you can give me some advice to reduce my nervousness. Looking forward to receive your reply.

Yours sincerely,

Li Hua
