There is no doubt that to study abroad gives you an excellent opportunity to learn things which are very helpful in your career building. Today Canada has earned a good name in providing quality education and safe healthy environment for its students. That is why more than 130,000 international students enroll (登记入学) every year in famous Canadian universities. It is an ideal education destination and gives students a unique experience education and its versatile (多样的) arts and culture. Canada spends a lot on education and is ranked the highest in G-8 countries.

    To study in Canada is very cheap．These universities are affordable compared to other universities in the world such as in the US, New Zealand and UK where cost of education and living is very high．According to a survey in 2006, “Canada offered the lowest tuition fees (学费) for foreign students compared to UK and Australia.”

    The low rate of crimes and the peaceful safe environment of the country also attract a lot of international students to Canadian universities. Canada has 92 universities and 175 community colleges and university degrees have three levels—Bachelor's, Master's and Doctoral.

    A Bachelor's degree in Canada is for three or four years' full-time study depending on the nature of the program you are doing. On the other hand, a Master's degree consists of two years of study. For a Doctoral program in Canadian universities, you require a minimum (最低/小的) of three to four or sometimes five years of research and study.

    You can also find many diploma (文凭) and certification (认证) programs in Canadian universities where the time is generally one year．Some of the Canadian universities are well-regarded worldwide and the degree and diploma obtained from these Canadian universities are recognized globally and promise bright future. After the completion of studies, a person could also find great job offers in Canada itself. International students require a work permit to work on campus.

    If you find yourself checking your phone first thing in the morning, if you find you're text-messaging while driving, checking your phone instead of working on an important assignment—you are addicted.

    Don't worry. The new NoPhone might be just the thing you need. It looks and feels exactly like a smartphone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

    NoPhone is currently a prototype(手机模型) that will cost only $12 once it hits the market. Its makers are trying to raise $30,000 in order to cover the production and marketing costs.

    Dutch designer Ingmar Larsen, who helped create the NoPhone, said that he had the idea as a joke along with his friends Van Gould and Ben Langveld. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhone of their own, so that's when the three friends decided to raise money for mass production.

David H said," I used to sleep with my phone in my hand, but my night errors would cause me to throw it across the room in an unconscious panic. With the NoPhone, I can still enjoy the comfort of holding a phone in my sleep, without waking up to a shattered screen, thanks, NoPhone."

If you're interested in NoPhone, but concerned about not being able to takeselfies anymore, don't worry. The makers do have an update at no extra charge—the mirror sticker. That way, they say, you can enjoy "real-time" selfies with your friends when they're standing right behind you.

    Social media is our new travel agent, and it's changing the places we go. In some cases, the places we go. In some cases, the newfound fame brought about by social media platforms has helped to boost local economies and bring tourists to places they might never have discovered otherwise. In other cases, it's creating problems for countries and cities that are simply not equipped to deal with the influx(涌入) of tourists. Check out two of the incredible locations around the world that have gone viral on social media.

    Iceland

    This northern island nation has seen a dramatic surge(激增) in visitors over the past few years. One reason for that is the so-called "Game of Thrones effect,". This, combined with the availability of cheap flights and some very effective marketing campaigns, has made Iceland a popular travel destination. The number of tourists almost doubled from 566,000 to over 1 million between 2011 and 2015, according to Iceland's tourism board.

    While this influx of visitors has brought a much-needed boost to the economy post-recession(经济衰退), it's also pushed up prices for residents and put pressure on the infrastructure. Locals complain of tourists destroying the fragile ecosystem and leaving a mess behind them as they trample over the formerly untouched natural sites.

    Cuba

    According to Cuba's ministry of tourism, four million visitors went to Cuba in 2016, an increase of 13 percent from the year before. The tourism boom has had some consequences for the country's residents, The New York Times reported in December 2016.

    The surge in visitors has led to a food shortage, and basic food items have become completely unaffordable for locals. Local hotels and restaurants are buying up supplies in bulk for guests, pushing up prices and leaving limited amounts for locals.

    The situation has been acknowledged by the Cuban government, who put caps on prices to make them more affordable for residents. This has only encouraged sellers to put products on the black market, according to The New York Times.

    Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.

    Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

    At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.

    This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(辐射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.

    Radiation can hurt us. We must know the truth.

Scientists have long thought about whether each animal species has a different language, much like different human languages that we cannot understand. Language experts agree on the fact that the way animals communicate through various calls does not fit the definition of human languages.

Animal calls are not considered a language because the calls are limited to signals related to food activities, warning about the presence of enemies and so on. They lack the characteristic of productivity that all human languages share. That is — humans create new expressions every day by combining different words to express meanings. Animal calls are fixed in their meanings, while human language goes further and includes expressions of complex ideas that do not have a limit.

However, animals do communicate. People who study humans believe that people speak with their entire bodies. To express a message, one does not always need words. Have you ever shared a private joke with your friends across the table? All you did was to give them a self-satisfied smile, Animals can communicate in much the same way as humans do. Although animals do not have the ability to speak words, they can use other methods, such as gestures, movements, calls and their sense of smell. In short, most of their communication is not related with speech.

If animals can make noises, why can't they talk? Humans and animals both have the necessary organs that produce sounds, such as lungs, throat, voice box, lips and tongue. But the differences lie in the movement and relative position of these organs that make it possible for us to speak.

When humans developed from apes, a lot of our features were improved to better shape sounds along the way. The mouth started getting smaller and the neck grew longer. All other animals, including our closest animal relatives — chimpanzees, have little similarity, which determines humans' ability to speak.

As the pandemic makes clear, cities are possibly humanity's greatest invention, but cities with huge populations also make us easily suffer from the rapid spread of disease. Yet humans aren't the only species that face this problem. Honeybees have lived social lives for tens of millions of years, making them some of the most experienced in the battle against infection. And over time, natural selection has given them quite a few impressive strategies for reducing transmission within bee groups.

However, these strategies are not enough to prevent every threat. Honeybees are battling their own global disease, for which they were totally not prepared. A parasitic mite (寄生螨) originally existed only in the groups of Asian honeybees, but later jumped to infect Western honey bees. Today, it has spread to every region where honeybees are kept except Australia and a handful of remote islands, quickly becoming a global disease of the bees.

If left untreated, a group of bees will typically die from the mites within two years. These infections, plus farm chemicals and poor nutrition, have forced beekeepers to struggle to keep their bees alive. Of the 2.6 million honeybee groups in the US, over half of them have parasitic mite.

And that's only the count of those bees that are tested and reported; the actual numbers are likely much higher. Beekeepers have still managed to slowly increase the number of groups they keep, on average, but at a much higher cost.

Western honeybees did not grow with parasitic mite, and the Western bees lack the behavioral features those Asian honeybees have, like permanently burying the members infested by parasitic mite and, perhaps the most extreme strategy, where the bees are so sensitive to parasitic mite that they completely die as soon as infected, sacrificing themselves to prevent the mite from reproducing.
