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.

    Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.

    Two months ago Sue, 69, who has never suffered from asthma or any other breathing problem in the past, suddenly found herself hard for breath.

    “I felt as if my throat and oesophagus (食道) were closing up,” says Sue.

    Sue is convinced the problem is related to the indoor swimming baths. “I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,” she says.

    She may be right, because although a trip to the pool is the perfect exercise for many, the chlorine (氯气) used to keep the water free from germs can lead to problems.

    But in most cases it's not the chlorine that causes problems, but the by-products formed when chlorine interacts with other substances — and this is mostly due to people not showering before they enter the pool.

    “This then poisons the water for them and for others,” says Dr. Hull. “The chlorine interacts with sweat and urine(尿素) on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in.”

    Chloramines are heavier than air so hang over the water where they are easily breathed in. Some believe they may cause lung disorders. A Swedish study in 2013 examining the health of 146 workers at 46 indoor pools found that 17 per cent had airway trouble at work — but no problems at home.

    As Dr. Hull says: ‘People need to remember that showering isn't just for them. It is for the greater good.'

    The popular TV program Readers has prompted more people in China to practice reading aloud in booths(亭) set up in big cities across the country．

    As the latest TV show to help people's love for literature recover, CCTV program Readers invites people from all walks of life to read aloud their favorite poems，essays and books，or even personal letters they wrote to their loved ones．Just as the weekly show has been well-received，its reading booths, equipped with professional recording devices and cameras，have become instant hits．

    A crowd of more than 200 people were pictured lining up outside the Shanghai Library at 11 a.m. on March 4 — the first day of the booth's opening to the public in Shanghai. The deadline for registrations was brought forward to 2 p.m. instead of the scheduled 5:30 p.m., as the number of waiting readers continued to grow. Some waited more than nine hours for a try-out in the booth, according to library management．

     “There is an old photo in the late 1970s capturing people lining up outside the Shanghai Library before it opens. If that was a spring of reading in Shanghai, now I think another spring has arrived again.” library manager Zhou Deming, told the Shanghai-based The Paper．

    The reading booth is the only one of its kind in the city of economic center at the moment, but more are expected to be put into use in the coming months, according to the library's website．

    The Readers program has also led to booths in other cities including Beijing, Hangzhou, Guangzhou and Xi'an to appeal to more people to read and share their life stories．

    With the recent boom of culture-themed TV shows such as Readers and Chinese Poetry Competition，some are optimistic that this will help the country love literature and reading again in general．

    It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad!

    The male giant water bug (雄性负子蝽) doesn't seem to mind a heavy load (负荷物) on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch (孵化). The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back.

    Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young — as many as 100 — until they can live on their own.

A similar example can be found in emperor penguins (帝企鹅) living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39℃. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born!

    Some people dream about becoming engineers. Luckily, the new IMAX film Dream Big shows how engineering can improve people's lives. It teaches viewers how engineers use high-tech to help the world. The film hits IMAX theaters nationwide on February 17 to celebrate Engineers Week.

    The film, taking place in locations like China, Dubai and Africa, tells the stories of engineers who try to come up with creative ideas to save energy and help people.

    Dream Big was directed by Greg MacGillivray who has 38 films under his belt, including some of the most successful films ever shown in IMAX theaters.

    How did MacGillivray get into the moviemaking business? “I grew up at the beach. My first movies were about surfing and the ocean. As time went on, I saw the changes in the ocean including polluting and overfishing. So I started making films about conservation of nature.” He told TFK. Now, his films cover a variety of topics, from the natural world to human creation.

    One of the engineers in Dream Big is Angelica Hernandez. In high school, she was on a team that best MIT, a university, in an underwater robotics competition. Today, the engineering work she does focuses on helping people use less energy and save money and resources. “I work with companies to promote energy efficiency with their commercial customers, so it's really trying to push forward all the measures that customers and high-energy users can apply, she explains.

    Engineering is such a good job-you make good money, travel around the world, solve amazing problems and help people.” She says.

    The mission of Dream Big is to show people the good that engineers can do to the world. “That was the impulse of making this movie”, MacGillivray explains, “We want to explain engineering in a way that will get the kids very excited about it.” “Whoever and wherever you are, you can become an engineer,” he adds, “All you need is the creative spirit.”

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.
