Here are some undiscovered places around the world, which will surely impress you.

Byblos, Lebanon

    This quiet settlement north of Beirut in Lebanon has been around a really long lime. Today, its rich history is well-represented in its ruins, which include ancient temples and tombs and Neolithic houses. Three sites in particular steal the show: the restored Roman amphitheatre (圆形剧场）, the grand 12^th century Crusader castle, and the beautiful]y restored medieval open market.

Carreg Cennen, Carmarthenshire, Wales

    The ruins of Carreg Cennen must be among the most noticeable sites in Wales. Carreg Cennen is defended by two drawbridges and three gate towers, although it hasn't seen much action since it was partly damaged in 1462, during the Wars of the Roses. However, one rare feature of the castle is unchanged. Ifs the stone passage that leads down to a natural cave underneath.

Providence, Rhode Island, US

    Rhode Island is the smallest state in the US. Its capital, Providence, has many of the attractions. Ivy League member Brown University and the famous Rhode Island School of Design (RISD) give the city a strong student influence. Up on College Hill, east of the Providence River, are streets lined with 18^th century wood framed houses.

Sequoia National Park, California, US

    Not content with having the worlds tallest (coast redwoods) and oldest (bristlecone pines), California is also home to the largest tree—the giant sequoia (红杉树). It grows only to its lull size in the Sierra Nevada mountains. Many of these trees are found in the Yosemite National Park, but for more quality time with the trees, it's best to head south to the far less known Sequoia National Park, which gets a quarter of Yosemite's visitor numbers.

    Peter Huszcz once taught in an agricultural (农业的)college. In the 1990s, he moved to Canada. Peter started out washing dishes in a restaurant in downtown Ottawa. When the manager asked him to help out rolling meatballs in the kitchen, he soon 1earned how to do the job very well. But it was boring and Peter suggested that the manager should buy a meatball-making machine. When the manager told him there was no such thing as a meatball maker, Peter was quick to notice that something was missing in the market. Putting his engineering knowledge to good use, he quickly came up with a simple method—the Magic Meatball Maker.

    He was sure there was a market for his machine. but it took him ten years of hard work to find it. He had to take risks, but he believed in his idea, and he managed to persuade other people to believe in him too. A local manufacturer (制造商) offered to produce the first 1,000 units in return for a share in the profits (收益), local shops offered to keep his meatball makers and a friend's daughter helped him out with his first sales.

    But his lucky break came when he managed to persuade a TV shopping channel to help sell the Magic Meatball Maker. The channel broadcast a program about how the invention worked in the studio kitchen. Within minutes, they had sold more than 4,000 units.

    This was just the start. Peter had been right. He had said his meatball maker would bring him great wealth, and it has: more than two million dollars so far and it's till selling to thousands of American housewives all across the USA.

    The following is a timetable in Guangzhou Baiyun International Airport.

    The key to effective cross-cultural communication is knowledge. First, it is essential that people understand the potential problems of cross-cultural communication, and make a conscious effort to overcome these problems. Second, it is important to assume（假定）that one's efforts will not always be successful, and adjust one's behavior appropriately.

    For example, one should always assume that there is a great possibility that cultural differences are causing communication problems. One should respond slowly and carefully in cross-cultural exchanges, not jumping to the conclusion that you know what is being thought and said.

    William Ury's suggestion for heated conflicts is to stop, listen, and think, or as he puts it "go to the balcony" when the situation gets tense（紧张的）. This helps in cross-cultural communication as well. When things seem to be going badly, stop or slow down and think. What could be going on here? Is it possible that I misinterpreted what they said?

    Active listening can sometimes be used to check this out—by repeating what one thinks he/she heard, one can confirm that he/she understands the communication accurately.

    Often intermediaries（调解人）can be helpful in cross-cultural communication situations. They can translate both the essential meaning and the manner of what is said. For example, they can tone down strong statements that would be considered appropriate in one culture but not in another, before they are given to people from a culture that does not talk together in such a strong way. They can also adjust the timing of what is said and done. Some cultures move quickly to the point; others talk about other things long enough to establish a relationship with the other person. If discussion on the primary topic begins too soon, the group that needs a "warm up" first will feel uncomfortable. An intermediary who understands this can explain the problem, and make appropriate adjustments.

    Over the past 10 years, developments in technology have moved the dream of personal fling vehicles closer to reality. The British company Malloy Aeronautics has developed a model of its flying bicycle. The company says its Hoverbike will be a truly personal flying vehicle.

    The company's marketing sales director Grant Stapleton says the Hoverbike is able to get in and out of small spaces very quickly and can be moved across continents very quickly because it can be folded and packed.

    Safety was the company's main concern when developing the Hoverbike. The designers solved this problem by using overlapping rotors(重叠旋翼) to power the vehicle. With adducted rotors(内转旋翼) the rider immediately not only protects people and belongings if he were to hit them, but if the rider ever were to crash into somebody or something, it's going to bring the flying vehicle out of the air. The company is testing two models of the Hoverbike.

    In New Zealand, the Martin Aircraft Company is also testing a full-size model of its personal flying device, called Jetpack. It can fly for more than 30 minutes, up to 1,000 meters high and reach a speed of 74 kilometers per hour.

    Peter Coker, one officer from the company said Jetpack “is built around safety from the start.” In his words, “Reliability(可靠性) is the most important part of it. We have safety built into the actual structure itself, very similar to a Formula One racing car.”

    Jetpack uses a petrol-powered engine. It also has a parachute(降落伞) that can be used if there should be an emergency(突发事件). It opens at very low altitude(纬度) and actually saves both the flying vehicle and the pilot in an emergency.

    Mr. Coker says Jetpack will be ready for sale to the public by the end of 2019. He adds it'll have a price of about $200,000.

    Life in the summertime is often full of pests. Like most Long Island homeowners, I want to ensure my suburban life with pest-free living. So it was with wide-eyed wonder that I greeted the smiling exterminator (灭虫者) who rang my bell.

    “We'll be serving your neighbors, Mike and Sarah (I'm not familiar with either one by name),” he waved in the other direction. “Since we'll have a team here tomorrow, we're offering a discount.” He came out with numbers beginning from $299 then in seconds to $89.

    “You've probably been seeing the ant hills around.” he moved toward my front walkway and lawn. “And have you seen the bees that dig nests in the ground?” he continued with his head shaking up and down pushing me to do the same.

    “What we do is spray three feet out from your foundation and three feet up.” As he was talking, and without breaking eye contact, he opened his iPad cover and began operating at the screen to show me frightening images. “It also kills other pests, like spiders. It is the best pesticide (杀虫剂),” he said, pausing for effect.

    He then went into soft talk to close the deal, correctly foreseeing that I would be concerned about safety and the environmental impact on my vegetable garden, plants and our little patch of planet here on Long Island. “The products are environmentally responsible, safe with children and pets,” he said.

    I'm unkind when it comes to unwanted visitors entering on my out-of-doors moments. Any insect found in my house or on my deck is bound to be poisoned or pancaked.

    Unfortunately for the exterminator, just as I was considering making an appointment, Billy, my fearless husband, pulled into our driveway, which made me ask for a business card out of politeness instead.
