Jane Eyre

    Jane Eyre, a novel written by Charlotte Bronte, was published in 1847 in England. It is Charlotte Bronte's most famous book. Jane Eyre is a love story. It tells about a young and independent woman called Jane Eyre, who is brave enough to pursue her own love.

Uncle Tom's Cabin

    Uncle Tom's Cabin is an anti-slavery novel by American author Harriet Beecher Stowe. Published in 1852, the novel “helped lay the base for the Civil War”, according to Will Kaufman. When Abraham Lincoln met Stowe at the start of the Civil War, Lincoln declared, “So it is the little lady who started this great war.” The character of Uncle Tom in the novel is a longsuffering black slave. The sad novel exposes the reality of slavery.

Gone with the Wind

    Gone with the Wind is a novel by Margaret Mitchell in 1936. It tells the story of Scarlett O'Hara, and her adventures in the American South during the Civil War. She falls in love with Rhett Butler, a city gentleman. It is one of the most famous books of its time, and was made into a movie with the same name. The title took its name from the lines an Ernest Dowson poem: “I have forgotten much, Cynara! Gone with the wind.” (This line also appears in the book.) The book won the Pulitzer Prize on May 3,1937.

Rich Dad Poor Dad

    Rich Dad Poor Dad is a book by Robert Kiyosaki and Sharon Lechter. In the story, Robert's own father was the superintendent (厅长) of education in Hawaii and end up dying penniless. His best friend's father dropped out of school at age 13 and went on to become one of the wealthiest men in Hawaii. It advocates financial independence through investing, real estate (地产), owning businesses, and the use of finance protection tactics.

    Freedom and Responsibility

    Freedom's challenge in the Digital Age is a serious topic. We are facing today a strange new world and we are all wondering what we are going to do with it.

    Some 2,500 years ago Greece discovered freedom. Before that there was no freedom. There were great civilizations, splendid empires, but no freedom anywhere. Egypt and Babylon were both  tyrannies, one very powerful man ruling over helpless masses.

    In Greece, in Athens (雅典), a little city in a little country, there were no helpless masses. And Athenians willingly obeyed the written laws which they themselves passed, and the unwritten, which must be obeyed if free men live together. They must show each other kindness and pity and the many qualities without which life would be very painful unless one chose to live alone in the desert.The Athenians never thought that a man was free if he could do what he wanted. A man was free if he was self-controlled. To make yourself obey what you approved was freedom. They were saved from looking at their lives as their own private affair. Each one felt responsible for the welfare of Athens, not because it was forced on him from the outside, but because the city was his pride and his safety. The essential belief of the first free government in the world was liberty for all men who could control themselves and would take responsibility for the state.

    But discovering freedom is not like discovering computers. It cannot be discovered once for all. If people do not prize it, and work for it, it will go. Constant watch is its price. Athens changed. It was a change that took place without being noticed though it was of the extreme importance, a spiritual change which affected the whole state. It had been the Athenian' s pride and joy to give to their city. That they could get material benefits from her never entered their minds. There had to be a complete change of attitude before they could look at the city as an employer who paid her citizens for doing her work. Now instead of men giving to the state, the state was to give to them. What the people wanted was a government which would provide a comfortable life for them; and with this as the primary object, ideas of freedom and self-reliance and responsibility were neglected to the point of disappearing. Athens was more and more looked on as a cooperative business possessed of great wealth in which all citizens had a right to share.

    Athens reached the point when the freedom she really wanted was freedom from responsibility. There could be only one result. If men insisted on being free from the burden of self-dependence and responsibility for the common good, they would cease to be free. Responsibility is the price every man must pay for freedom. It is to be had on no other terms. Athens, the Athens of Ancient Greece, refused responsibility; she reached the end of freedom and was never to have it again.

    But, “the excellent becomes the permanent”, Aristotle said. Athens lost freedom forever, but freedom was not lost forever for the world. A great American, James Madison, referred to: “The capacity (能力) of mankind for self-government.” No doubt he had not an idea that he was speaking Greek. Athens was not in the farthest background of his mind, but once man has a great and good idea, it is never completely lost. The Digital Age cannot destroy it. Somehow in this or that man's thought such an idea lives though unconsidered by the world of action. One can never be sure that it is not on the point of breaking out into action only sure that it will do so sometime.

    We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    The concept of good manners varies a lot when we compare different cultures, values and ways of living. However, when we talk about the western part of the world, the differences are not so big. In my opinion, going to a restaurant in Brazil will rarely be an embarrassing situation. But there are some basic and necessary rules of etiquette(礼节)that Brazilians usually respect every day. They are:

    ●Being on time is polite, but it is not a strict rule in Brazil. Being late for up to 15 minutes probably will not make a Brazilian angry.

    ●When you go to a restaurant, be careful to greet the people who work at the place, and don't forget to greet the people who are already waiting for you at the table. It's not necessary to hug or kiss everybody if they are already seated.

    ●You can ask somebody about how the food is prepared and also about prices or tips if you are not sure about them.

    ●Before they start eating, Brazilians usually say “born appetite” to their friend.

    ●You should never talk to another person while you still have some food in your mouth.

    ●Making noise while eating is also considered really rude. Avoid doing it.

    ●Be careful not to put your elbows on the table while eating. It is not terrible, but it can be considered a little bit rude by some people.

    ●Don't worry about the time. Usually people in Brazil stay seated for a long time, especially when they have interesting things to talk about.

    ●It's not necessary to talk in a really low voice because people there usually talk in a little loud voice. But please, don't exaggerate.

    ●Finally, saying “thank you” and “bye” are always seen in Brazil.

Urban Transportation in Canada

    Public transportation & Transit passes

    All cities and most major towns in Canada have a public transportation system with one or more modes of transportation (bus, subway, train, etc.). The bus is the most common form of urban transportation in Canada. To use public transportation, you must purchase a ticket or a transit pass. Transit passes allow you unlimited use of public transportation for a specific period (one month or more). They are usually cheaper than buying many tickets if you plan to use public transportation often.

    Transportation for people with disabilities

    Public transportation often has features to assist people with disabilities. In many cities and towns, there are also transportation services available specifically for people with limited mobility, such as specially equipped buses. You can find out about these services in the same way you would learn more about other public transportation options.

    Etiquette on public transportation

When taking public transportation such as a bus or train, it is important to understand the unspoken rules of conduct in the shared space. Here are a few things to note:

    Be polite and respectful to others around you. For example, maintain an appropriate noise level when talking or making a phone call.

    If you are carrying a backpack or a large shoulder bag in a crowded public transit vehicle, keep it close to you, preferably at your feet to avoid hitting people with it as you walk by.

    Avoid pushing or touching others in order to make more room for yourself. Sometimes public transit can become very crowded, but it is important to keep calm and give others appropriate personal space.

    Have your proof of payment accessible in case you are asked to show it.

As the world deals with the rising temperatures brought by climate change, the demand for cooling solutions in hot, dry regions becomes increasingly pressing. However, traditional air conditioning systems produce massive greenhouse gases and use lots of energy.

Facing these challenges, a research team from McGill University, UCLA, and Princeton have found an inexpensive, sustainable cooling method. Their approach not only offers a solution for cooling but also promises to address the problem of heat waves during electricity blackouts.

The researchers set out to achieve a new standard in passive cooling (无动力制冷) within naturally conditioned buildings in hot climates such as Southern California. They aimed to address an important question: how can passive cooling techniques outperform traditional air conditioning units and improve indoor comfort?

The key to this breakthrough lies in harnessing the potential of radiative (辐射的) cooling materials, specifically in the context of housing design. Traditionally, such materials have been employed to prevent roofs(屋顶) from overheating and improve heat rejection from cooling systems. However, the research team recognised that there is under-explored potential in integrating these materials into building design — they can not only remove waste indoor heat but also drive regular and healthy air changes.

Lead author Remy Fortin stated, "We found we could maintain air temperatures several degrees below the surrounding temperature."Remarkably, they achieved this success without giving up a healthy airing. This was never a piece of cake, considering air exchange can unintendedly introduce heat into the building when the goal is to keep the inside cooler than the outside.

The researchers are hopeful that their findings will be used to positively impact communities suffering from climatic heating and heat waves. Salmaan Craig, the principal researcher expressed their expectations: "We hope that materials scientists, designers, and engineers will be interested in these results and that our work will inspire more broader thinking for how to integrate breakthroughs in radiative cooling materials with simple but effective solutions."
