It has been several weeks since we tookour daughter to college and she seems to be adjusting  well after a short period of homesickness.For us, though, it's another story. Like most parents, I love checking in on mychildren at night. But now she's gone, and I find nighttimes the hardest. Imiss her most at night.

    In my neighborhood, most of the parentswhose kids are off to college are dealing with similar melancholy. Myhusband is filled with anxiety. One friend talked about getting this sickfeeling in her stomach as she prepared for the college drop-off. We complainedthat many of us were too busy to truly enjoy being with our children while wehad them.

    For us moms, seeing Toy Story 3 onlymade the sadness worse as we watched the character Andy, who is the same age asour kids, say goodbye to his childhood as he prepares to leave for college. Andit's not just “first-time” parents like me. Two moms who have kids already wellinto college said the separation didn't get any easier. “You feel likesomething has been taken away from inside you,” said one of them.

    I imagine things will get easier withtime, especially as I see my daughter adjust to college life. Meanwhile, as Ikeep my cell phone close to me in bed and text my daughter goodnight and sweetdreams every night, I like to think at messages serve as a night light thatkeeps her safe.

    It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.

    In recent years, many writers have begun to speak of the 'decline of class ' and 'classless society ' in Britain. And in modern day consumer society everyone is considered to be middle class.

    But pronouncing the death of class is too early. A recent wide-ranging study of pubic opinion found 90 percent of people still placing themselves in a particular class; 73 percent agreeed that class was still a vital part of British society.; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an imprtant part of British society. Britain seems to have a love of stratification.

    One unchanging aspect of a British person's class position is accent. The words a person speaks tell her or his class. A study of British accents during the 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounds 'educated ' and 'soft '. The accents placed at the bottom in this study, on the other hand, were regional(地区的) city accents. These accents were seen as 'common ' and 'ugly '. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

    In recent years, however, young upper midder-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ' Common People ' puts forward the view that though a middle-class person may ' want to live like common people ' they can never appreciate the reality of a working class life.

    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes. To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.

    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random (随机地) from the population, it is likely that their degrees of intelligence will be completely different. I f on the other hand we take two identical (完全相同的) twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.

    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.

I am asked repeatedly why anyone would want to keep an "'ugly" building or a building that is dirty and clearly in need of work, I guess you could say we preservationists (文物保护者)look at buildings through a different angle - an angle that can see the swan in the ugly duck the story in the simple lines, and the book behind the cover.

The Queen Emma Building is remembered by many as one of the ugliest buildings in town. Yet the angle from which a preservationist views the building is that it is uniquely constructed with an artistical sun shield to block the sunlight, a decorative wall designers used concrete bricks to form. Unfortunately, it was removed in 20il, making the building one of many contemporary buildings in town.

Other times, when a beautiful site is replaced by a "horrible" building, people hate it and can't get over their anger, even when that: "horrible" building becomes an important part of our story. This is particularly true in San Francisco with many Victorian buildings, which are many preservationists' favorite. Yes, it was a tragedy, that many Victorian buildings got torn down several decades ago, but those losses also tell another important story. It tells the story of the1950s and 1960s when there was hope for a more equal society with in expensive housing for the working class. Should that history be wiped from our memories? 

Preservation is not just about keeping pretty, well-kept buildings, but about holding on to parts of our history - not just the history of huge events, but the story of how everyone used to go to a certain corner market. Our history cannot be told only in buildings that meet someone's criteria of beauty, sometimes our history is, painful, but no less important.

Max Du emerged victorious at the Canada-Wide Science Fair with an innovative project that could revolutionize emergency response: a drone designed to assist individuals experiencing cardiac arrest. His creative spark was ignited during the Christmas break of the previous year when he received a toy drone from his parents. Due to the snowy conditions, Max was unable to fly his new gadget outdoors, prompting him to explore its potential as an indoor robot that could be of service to people in need.

In Canada, approximately 35,000 individuals suffer from cardiac arrests annually, with the majority of these incidents occurring outside of hospital settings. Sadly, less than 10 percent of these individuals survive. Max was convinced that a drone could provide more rapid assistance and deliver life-saving medication, but he knew he had to construct one himself to validate his hypothesis.

The process of testing his drone spanned six months, during which Max's parents had to tolerate their son's persistent drone flights and mishaps within their home. Each innovative feature Max developed, such as a deployable arm, added weight to the drone, causing it to disintegrate. This necessitated the purchase of new components. Through experimentation, Max eventually discovered a more lightweight material, leading to a better-balanced design.

After a series of trials and adjustments, the 14-year-old successfully perfected his drone. It is now capable of opening door handles, navigating through the air, and landing gently on the ground. The drone features a new extendable arm designed to administer injections or deliver crucial medication to a patient. Additionally, an integrated camera allows for direct communication with an emergency response team, enabling remote monitoring of the patient.

Max is looking forward to filing for a patent to establish connections within the healthcare sector and bring his invention to fruition. He spent his summer acquiring knowledge in artificial intelligence at Stanford University in California, where he was one of only 32 students chosen globally. Following this, he will attend the University of Pennsylvania to enroll in a college-level robotics course before resuming his high school studies in September.
