Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

    Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

    Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

Current Culture: Is Common Culture Alive?

    The digitizing and globalizing world is changing the working of culture. As some see it, cities and nations are losing their common culture and their general spirit: people can no longer count on those around them valuing any of the same music or films. Others argue that a common culture is not dying so much as changing forms: it is less and less attached to a particular area and ever more linked to global networks.

    The facts lead to the change that anyone can become a cultural producer today, that the culture is increasingly available everywhere you want it, and whenever you want it, not just in the two months after the movie or book came out. Cultural possibilities have multiplied as a result, but the change also means fewer cultural moments. It is easy to find the change in terms of loss of diversity of society. So what will it mean if globalization turns us into one wide world culture?

    For the enthusiasts of these changes, culture is not about popular artists or books, but centers on platforms like Google and Wikipedia, where every variety of culture brings about the exchange of knowledge and ideas, and makes connections across boundaries. It is perhaps debatable whether two people who have participated in such websites, but in totally different corners of them, have had a cultural experience in common. In fact, these platforms become very successful with a large crowd of people, who build things together, share information, and forward articles back and forth. Here are still more questions. What does it mean for the future of countries that culture now goes beyond the limits of the nation? Is there anything to defend and preserve in the passing cultural world, or is that merely to favor pen over printing press, horse over automobile?

    Up to now a growing quantity of culture has been globally spreading and developing. More individuals (个人) than ever have the chances to be makers of culture, even if that means more to choose from and fewer standards to be reached in common. What it means is this strange feeling: that of being more connected than ever, with one-click access to so much of the cultural harvest around the world, and yet, of being starved for having similar interests and opinions with others, concerned only with ourselves.

    On a recent visit to the Museum of Modem Art with a friend and her daughter,wandering through the museum's exhibits,I was struck by how often my friend's 13-year-old daughter asked us to take photos of her with her smart phone in front of the artwork.Then,she gazed at the photos which she would then post on Instagram,Snapchat and all the rest.She was not the only person who was doing this; it seemed everyone was busy taking photos of themselves "experiencing" the museum.

    This is by no means a criticism of my friend's daughter or anyone else.What was concerning,at least to me,was that in between being photographed and posting,my friend's daughter had no interest in the artwork,a fact which didn't seem to matter or have anything to do with wanting to post herself as someone enjoying the experience.

    When I was her age,I had no interest in going to museums either.Having no interest in art at her age (and any age) is completely normal.But what is disturbing is how much of a young person's energy these days goes into creating an image of the life they're living and the character they "are" in that life.While creating a self-image has always been a big part of growing up and figuring out our identity,social media seems to have changed the rules of the game.Social media has not just increased the pressure and possibility of creating a self-generated（自我创造的）  self-image,but also distorted（歪曲）the process through which we become who we are.Young people now seem to be creating an image of who they are in place of becoming who they are,posting their life rather than living it.

    Social media has turned life and its experiences into an exercise in narcissism（自恋，自我陶醉）.No matter what the experience is actually about,it becomes about you,the person who is living it.A concert is not about the music,a restaurant not about the food and a sport event not about the sport;it's all about you,the doer,and what the event says about you.As a result the more we use life create an identity,the more distant from life we feel.Instead of being part of it,we feel as if we have to keep generating new life material.

    I hope the next time you post your story,pause for a moment and experience where you are,feel what it feels like to live what you're living without using life for your benefit,or for anything at all.Just live,without the narrative（叙述）.While you may feel this practice is a threat to your identity,causing you to miss a chance to prove your value,in fact,the benefit will far outweigh any loss it brings.

Yawning（哈欠）sends out certain messages—either “Oh, this movie is boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is so overheated?

    A new study, led by a research team of Princeton University, has indicated（表明）that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily.com.

    The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.

    When people yawn, their jaw is also stretched, which increases blood flow and may also help cool the brain.

    The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawn. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.

    However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.

    According to Gallup, this is the first report to show that yawning frequencies(频率) change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.

    2.26-meter-tall Yao Ming made his NBA debut (初次登台) on October 23, 2002 and got 6 points for the Houston Rockets in the game. The next day, he got 13 points in another game.

    Most people think that Yao Ming is a born basketball player. But Yao said, "When you watch it on TV, it looks very easy. But when you are playing in the NBA, it is really not so easy." He said that joining the Houston Rockets was a new start and a new challenge. "I hope that through very hard work I can make everyone happy and help the Rockets win more games," he said. Yao Ming speaks some English. Both he and his teammates can understand each other. They don't think there is a language problem. While Yao Ming faces this new challenge, the people of Houston have shown great interest in him and they hope Yao Ming will bring new energy to the Rockets. The team has started having lessons to learn more about China, and many people who work for the Rockets have learned to speak some Chinese.
