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.

    Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention to class.

    Opposite to what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.

    It's a real case of fish out of water. Blennies (鲇鱼) in the South Pacific Ocean are gradually relocating to land to escape their predators (捕食者), in an example of evolution in action.

    Fish first began crawling onto dry land about 400 million years ago, kicking off an evolutionary chain of events that led to humans. But their reasons for exiting the sea have been uncertain.

    To look for clues, Terry Ord at the University of New South Wales in Australia has been studying several species of blennies at Rarotonga, the largest of the Cook Islands.

    At low tide, blennies are commonly found swimming in rock pools around the edges of the island. But when high tide moves in, they climb up to dry land and move around the rocks until the tide retreats.

    The researchers found that this is most likely to avoid predators that swim in with the rising tide – mainly bigger fish like lionfish.

    To test what would happen if blennies did not have an escape plan, they made blenny models and sank them in the sea. The mimics ended up with wounds, bite marks and chunks-missing.

    Of course, there are still dangers for blennies on land, like the occasional bird attack, but the predation risk on land is a third that of underwater.

    What's more, moving onto land has additional benefits for blennies. Holes in the rocks provide sheltered nests for laying eggs, and they can maintain their diet of bacteria.

    In fact, several species of blenny fish at Rarotonga have already made the full transition to land-dwelling (陆生的) species. They continue to breathe with their gills, but have developed stronger tail fins and jump from rock to rock.

    Ord believes that many evolutionary processes have been driven by the need to escape predators. “It is often assumed that animals move homes to find new sources of food, but in many cases, escaping predators is a stronger motivation.” he says.

    I prefer Lynne Truss's phraseology: I am a grammar "sticker". And, like Truss—author of Eats, shoots & Leaves – I have a "zero tolerance" approach to grammar mistakes that make people look stupid.

    Now, Truss and I disagree on what it means to have "zero tolerance". She thinks that people who mix up basic grammar "deserve to be struck by lightning, hacked (砍) up on the spot and buried in an unmarked grave", while I just think they deserve to be passed over for a job—even if they are otherwise qualified for the position.

    Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a compulsory grammar test. If job hopefuls can't distinguish between "to" and "too", their applications go into the bin.

    Of course, we write for a living. iFixit.com is the world's largest online repair manual (指南), and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a strong strike against grammar errors.

    But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the Internet. And, for better or worse, people judge you if you can't tell the difference between "their" "there" and "they're".

    Good grammar makes good business sense—and not just when it comes to hiring writers. Writing isn't in the official job description of most people in our office. Still, we give our grammar test to everybody, including our salespeople, our operations staff, and our programmers.

    Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing—like stocking shelves or labeling parts. It is the same with programmers. Applicants who don't think writing is important are likely to think lots of other things also aren't important.

    A recent documentary produced by the British Broadcasting Corporation (BBC) has caused a stir in China and in the UK.

    The documentary, titled Are Our Kids Tough Enough? focuses on five Chinese teachers who are sent to teach 50 UK teens at a school in Hampshire.

    The teachers instruct the students for a month. The pupils are then tested, and the results are compared to the ones of those who have continued in the regular UK education system. The idea is to see if the Chinese method improves academic performance.

    The Chinese teachers use their own teaching methods but receive strong resistance from the students. A clip from the documentary online shows some problems, with Chinese teachers calling their students lazy and lacking in discipline, while the students say the high pressure and harsh teachers are driving them crazy.

    This has aroused a new debate in both China and the UK, with some arguing the teenagers need more regulation and discipline. Others say Chinese methods encourage rote learning (死记硬背) instead of independent thinking. For instance, Chinese language teachers should do more than pass on knowledge about words and characters. They should inspire students, helping them feel the sentiment from Chinese literature. This is a higher level of teaching.

    Yang Dongping, dean of the 21st Century Education Research Institute, says, "The Chinese teaching methods are designed to strictly train the majority. Foreign teaching methods, however, are more natural and relaxing, and designed to inspire students' interest in learning. Education methods are based on culture. That is why a successful education method in one place may not work that well when simply 'transplanted' into another place."

    Yang Dongping says, "The documentary does reflect some problems rooted in traditional Chinese teaching methods. Nobel prize winner, Yang Zhenning, gave a very fair comment on this issue. He said the Chinese-style education method works for most ordinary qualified students effectively, helping them reach high standards. However, it may weaken the training for high-potential outstanding students."
