Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight?

    In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love.

    Passionate love is rooted in the reward circuitry of the brain—the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner.

    What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what their overall weight is. (This ratio may indicate a woman's reproductive health.)

    Another piece of evidence comes from work by a psychologist at Ben-Gurion University, who found in a survey that a small percentage (11%) of people in long-term relationships said that they began with love at first sight. In other words, in some couples the initial favorable impressions of attractiveness triggered love which sustained a lengthy bond. It is also clear that some couples need to form their bonds over a longer period, and popular culture tells many tales of friends who become lovers.

    One might also assume that if a person is looking for a partner with traits that cannot be quantified instantly, such as compassion, intellect or a good sense of humor, then it would be hard to form a relationship on the basis of love at first sight. Those more concerned with visual appearances, though, might find this easier. So it appears that love at first sight exists, but is not a very common basis for long-term relationships.

    After finishing my teaching for a school year, I thought that I should go back to Montreal, Quebec, my hometown for a visit. My main goal was to relax in preparation for the challenges of my retirement in the coming year.

    Through my stay in Montreal, I met lots of Chinese who are struggling to succeed and then lead a better life in Canada.

    Some travelled thousands of miles to get knowledge. When I spoke with some of them about the major barrier they had to face after they arrived in Canada, they all talked about the two official languages of Canada. But I was impressed by their ability to express their ideas while switching between English and French.

    Almost all of those people said they often felt homesick. They miss their families and friends. Though Montreal has lots of Chinese restaurants, they long for a home-cooked meal.

    I met some tourists who were trying to realize their childhood dreams of experiencing the life in a developed country. When I asked them if Montreal had lived up to their expectations, they hesitated. They said that reality never agrees with fantasies. However, they were glad to have the opportunity to visit Montreal and didn't regret taking the trip.

    Not all the Chinese people I met were happy. I once met a young lady who met with a gentleman through the Internet. However, to her disappointment, he disappeared after he promised to marry her in Montreal.

    I was served by another Chinese person who could not handle the challenges of studying in an English environment and ended up working in a restaurant with minimum pay.

    Exploring different parts of the world, without any doubt, is an amazing experience. However, one should be realistic when it comes to leaving his hometown to set up a new life in a foreign country. One should take the time to examine the advantages and the shortcomings of the venture before they decide to chase an uncertain dream of achieving success or leading a better life.

    Do you often lose things? Don't worry. Now a new tool that can be connected to any object you might lose may be the way to solve your problem. The Tile, a small square connected to your iPhone or iPad by means of Bluetooth, allows you to see how close you are to your missing item, within a 50-to-150-foot range (范围). If the item goes out of your phone's 150-foot range, it can still be found on other smart phones with the same app.

    When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can connect your phone with up to ten Tiles. And if your lost object—a dog, for example, or a stolen bike—go out of your own phone's 150-foot Bluetooth range, you can set it as a “lost item”. If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the ability to remember where it last saw your Tile, so that you can easily find where you left it.

    Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn't to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads.

    "Do you like my dress?" She asked of a passing stranger. "My mommy made it just for me." She said with a tear in her eye.

    "Well, I think it's very pretty, so, why are you crying?"

    With a tremble in her voice the little girl answered. "After mommy made me this dress, she had to go away."

    "Well, now," said the lady, "with a little girl like you waiting for her, I'm sure she'll be right back."

    "No Ma'am, you don't understand," said the child through her tears, "my daddy said she's up in heaven now with Grandfather."

    The woman realized what the child meant, and why she was crying. Kneeling down she gently gathered the child into her arms and together they cried for the mommy that was gone. As the woman intended to go, the little girl grabbed her sleeve, pointing to a spot on her dress, saying, "Here is where my mommy kissed my dress, and here," pointing to another spot, "and here is another kiss, and here, and here. Mommy said that she put all those kisses on my dress so that I would have her kisses whenever I cry."

    Then the lady realized that she wasn't just looking at a dress, she was looking at a mother who knew that she was going away and would not be there to kiss away the hurts that she knew her daughter would get. So she took all the love she had for her little girl and put them into this dress. She no longer saw a little girl in a simple dress. She saw a child wrapped in her mother's love.

    Last Sunday, my whole family went to the amusement park near our hometown. As we planned the day before, on my brother's 13th birthday. David was two years older than I.

The weather was perfect and everyone was happy. The park was not too crowded. "Fioda," said my brother, "do you want to go on that ride with me?" "Of course," I said. The ride was brand new. I saw commercials(广告) for this huge roller coaster(过山车） on television. I was so excited to ride it. As we got in line, we talked excitedly about what we might experience. We decided that we would both try to keep our hands in the air the whole time. We believed that would make it even more enjoyable. I was so busy talking to my brother that I missed the most important sign—-Empty your pockets before going on the ride. Something bad happened!

    The ride started. It was a really fast roller! Before I knew it, we were upside down. I felt my phone slipping（滑落） from my pocket. My hands were in the air, just as we had promised, and I didn't catch my phone in time. It hit me on the head, fell down to the ground and broke. My parents said I wouldn't have a new phone until I had enough money to pay for it. I need to be more careful. Next time, I'll pay better attention the warning signs as we wait in line for the ride.
