Music is magic! Music speaks louder than words and it is a “language” that the whole world can understand. A piece of music can produce a response in the heart and mind. Like feeling an electrical current or receiving a personal radio signal, music has a spiritual effect on a person. Different kinds of music influence people in different ways.

    I have listened to music all my life. When I was twelve years old, the Beatles came to America and my whole world opened up. Maybe young people today cannot understand the influence of the Beatles when they exploded across America. Their influence changed the way we dressed, looked, acted and spoke... even our culture. The Beatles arrived in America from the UK just under three months after the assassination(暗杀) of President John Kennedy, which had put America into a great depression. And the freshness and lively spirit of the Beatles was exactly what the country needed to refresh itself.

    Music links the heart of the hearer with that of the composer. This means that it mixes the spirit of the composer with your spirit when you listen to it. And the music can take your spirit out of your body and transport you into another world. Music has a great way of touching people. Music can make you laugh, cry or shout. It's also a great source of inspiration.

    Try this one day and notice what happens: make yourself a cup of tea, sit on your sofa and play one of your favorite songs. Close your eyes, and soon you'll find yourself creating vivid mental images—matching the music that you are listening to.

    The UN refugee agency (难民署) is heaping pressure on Europe to help Italy defuse (平息) the “unfolding tragedy” of tens of thousands of migrants flooding its shores. Italy needs more international support to deal with a growing number of migrants who have braved a risky Mediterranean crossing to reach Europe this year, UN High Commissioner for Refugees Filippo Grandi said on Saturday.

     “What is happening in front of our eyes in Italy is an unfolding tragedy,” Grandi said in a statement. “In the course of last weekend, 12,600 migrants and refugees arrived on its shores, and an estimated 2,030 have lost their lives in the Mediterranean since the beginning of the year.” Italy, he said, was “playing its part” in taking in those rescued and offering protection to those in need. “These efforts must be continued and strengthened. But this cannot be an Italian problem alone.”

    Separately, a source in Paris said the interior ministers of France, Germany and Italy would meet in the French capital on Sunday to discuss an approach to help Rome.

    Violence in Calais

    Europe has been dealing with the worst migration crisis since the end of World War II with the arrival of large numbers of people fleeing the wars in Syria and Iraq while others from Africa are seeking an escape from poverty or political persecution (迫害).

    In the northern French port city of Calais, police stepped in over the past two days to break up fighting among African migrants armed with sticks and rocks. Calais has for years been a magnet (磁铁) for migrants and refugees hoping to cross the Channel to Britain.

    Last October, France broke up the disreputable tent camp known as “the Jungle” transferring thousands of migrants to centers around the country. But hundreds remain near the port, mostly Africans and Afghans, who fight sporadically with police as they make nightly attempts to stow away (偷乘) onto trucks heading across the Channel to Britain.

    You're happy to let your best friend borrow your mountain bike, but would you be willing to loan it out to a total stranger if you could make some money from the arrangement?

    That's the idea behind peer-to-peer (P2P) renting, a new model concluded by sites such as eBay and Craigslist. Instead of selling an idle (闲置) thing, you loan it to people in your town, get paid a small rental fee and gel it back when the borrower's done with it. In the past few years, almost a dozen websites have popped up promising to connect lenders and borrowers. For example, you can use GetAround to rent out your car or motorcycle, SnapGoods to rent out electronics and gadgets, ToolSpinner to rent electric drills and lawnmowers, Zaarly and Knb to rent out a little bit of everything else.

    Old as it may sound, P2P renting is more high-tech than before, with websites that avoid cash for credit cards. A user creates an online listing for the item she wants to rent out, choosing her own rental fee. When someone wants the item, he keeps it on an online calendar, and the two arrange a time and place for pickup. Each site operates a little differently, but all use technology to make renting easy, safe and relatively inexpensive.

    Why rent your idle things? You may not make a ton of money, but it is a good way to get some use out of idle things. The people who rent those goods are able to save thousands of dollars by renting instead of buying new.

    There may be other benefits. "It brings convenience, security and adventure," says Ali Hart, JustSharclt's spokesperson. “But, more importantly, we're really connecting people and building community, too."

    Get to know your neighbors and make a few dollars in the process? Sounds like a good deal.

    I use tea to refer to a snack(点心)taken in the late afternoon or early evening (ie after getting home from work but before the main meal, which I call dinner) and I don't think that's rare(罕见)at all. I think the difference is when you originally had your main meal and I would agree that it's a class thing, not a north/south thing(I've heard the midday meal referred to as both lunch and dinner by different people in all areas of England).

    Dinner was always the main meal. In the past, working class men worked near(or even at)home and came home for their main meal at midday, and so that was their dinner. Middle class men worked in offices far from their homes(often working in the city centre, and living outside the city) and so couldn't go home for a meal at midday. They therefore had a light meal at midday and had their main meal with their family in the evening after they go home from work, so dinner was in the evening. Because most children at state schools were working class, we still use dinner for school meals. For middle and upper class people, tea was a light snack served in the mid-afternoon at which ladies(who didn't, of course, go out to work)could entertain their friends. For working class people, however, tea was the light snack you had before going to bed. Supper, for all classes, was the light snack you had before going to bed.

    However, because work patterns changed and many working class people started eating their main meal in the evening too, dinner, tea and supper started to become interchangeable for them. Also many working class families have since become middle class, so the terms have become less of a current class thing(if class still exists at all) and more of a system of terminology inherited(家族术语)from grandparents etc, different from family to family. When I was a child(Southern English, middle class family, but with working class forebears(祖先)) we called the midday meal dinner and the evening meal tea, but when I was in my early teens I had a new stepfather(from a family that had always been middle class for generations)who used lunch and dinner, and that's what I've used ever since.

    It's common knowledge that the woman in Leonardo da Vinci's most famous painting seems to look back at observers, following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.

    A new study finds that the woman in the painting is actually looking out at an angle that's 15.4 degrees off to the observer's right­well outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, "She's not looking at you." This is somewhat ironic, because the entire phenomenon of a person's gaze (凝视) in a photograph or painting seeming to follow the viewer is called the "Mona Lisa effect" . That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as the angle of the person's gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.

    This is important for human interaction with on-screen characters. If you want someone off to the right side of a room to feel that a person on-screen is looking at him or her, you don't cut the gaze of the character to that side­surprisingly, doing so would make an observer feel like the character isn't looking at anyone in the room at all. Instead, you keep the gaze straight ahead.

    Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars(虚拟头像) when Horstmann took a long look at the "Mona Lisa" and realized she wasn't looking at him.

    To make sure it wasn't just him, the researchers asked 24 people to view images of the "Mona Lisa" on a computer screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected Mona Lisa's gaze. To calculate the angle of Mona Lisa's gaze as she looked at the viewer, they moved the ruler farther from or closer to the screen during the study. Consistently, the researchers found, participants judged that the woman in the "Mona Lisa" portrait was not looking straight at them, but slightly off to their right.

    So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isn't sure. It's possible, he said, that people have the desire to be looked at, so they think the woman is looking straight at them. Or maybe the people who first coined the term "Mona Lisa effect" just thought it was a cool name.

In the movie, The Day After Tomorrow, many climate changes including an ice age are caused by global warming. Much of the science in the movie has been questioned by people. However, there may be some truth to the idea in the movie that global warming could cause an ice age.

The theory starts with an understanding of why Europe and Scandinavia are not colder already. After all, other places at the same latitude(纬度) are covered with ice. The ocean current called the Gulf Stream brings warm waters from the Caribbean to the UK and Europe. These waters warm the countries around their path. This is why the UK, Europe and Scandinavia have a warmer climate than Alaska. Global warming has nothing to do with this. Global warming is significant. It could slow the Gulf Stream, or even stop it. If this were to happen, the cold waters would stay in the area of Europe, the UK, Scandinavia and the Northeastern US. It could mean an ice age for those regions.

Some weaknesses in the Gulf Stream could happen for different reasons. These days, it could happen due to global warming, caused by human activities, such as the burning of fossil fuels.

If a new ice age happened, it would probably be caused by the melting of the polar ice. This will lead large quantities of cold and fresh water to come into the ocean, which would disrupt the Gulf Stream and cause the cooling of many areas that now have a mild climate.

Scientists have gathered a lot of data from the oceans and the land to try to determine whether an ice age could be caused by global warming. With all this information at hand, it appears that it is indeed possible that global warming could lead to an ice age.
