Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least conventional and generally agreed.

    Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society-than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.

    Furthermore, social change is easier if it is gradual. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and white people.

    In 2004 ,when my daughter Becky was ten , she and my husband ,Joe, were united in their desire for a dog . As for me , I shared none of their canine lust.

    But why , they pleaded. “Because I don't have time to take care of a dog.” But we'll do it. ” Really? You're going to walk the dog? Feed the dog? Bathe the dog?” Yes, yes , and yes .”I don't believe you .” We will . We promise.

   They didn't . From day two (everyone wanted to walk the cute puppy that first day ) , neither thought to walk the dog . While I was slow to accept that I would be the one to keep track of her shots , to schedule her vet appointments , to feed and clean her , Misty knew this on day one . As she looked up at the three new humans in her life (small, medium, and large) , she calculated ,”The medium one is the sucker in the pack .”

    Quickly, she and I developed something very similar to a Vulcan mind meld (心灵融合) . She'd look at me with those sad brown eyes of hers , beam her need , and then wait , trusting I would understand — which , strangely , I almost always did . In no time , she became my feet as I read , and splaying across my stomach as I watched television .

    Even so , part of me continued to resent walking duty . Joe and Becky had promised. Not fair , I'd balk (不心甘情愿地做) silently as she and I walked . “Not fair , ” I' d loudly remind anyone within earshot upon our return home .

    Then one day — January 1, 2007 , to be exact — my husband ‘ s doctor uttered an unthinkable word : leukemia ( 白血病) .With that , I spent eight to ten hours a day with Joe in the hospital , doing anything and everything I could to ease his discomfort. During those six months of hospitalizations, Becky, 12 at the time, adjusted to other adults being in the house when she returned from school. My work colleagues adjusted to my taking off at a moment's notice for medical emergencies. Every part of my life changed; no part of my old routine remained.

    Save one: Misty still needed walking. At the beginning, when friends offered to take her through her paces, I declined because I knew they had their own households to deal with.

    As the months went by，I began to realize that I actually wanted to walk Misty. The walk in the morning before I headed to the hospital was a quiet, peaceful time to gather my thoughts or to just be before the day's medical drama unfolded. The evening walk was a time to shake off the day's upsets and let the worry tracks in my head go to white noise.

    When serious illness visits your household, it's , not just your daily routine and your assumptions about the future that are no longer familiar. Pretty much everyone you acts differently.

    Not Misty. Take her for a walk, and she had no interest in Joe's blood counts or 'one marrow test results. On the street or in the park, she had only one thing on her mind: squirrels! She Was so joyous that even on the worst days, she could make me smile. On a daily basis she reminded me that life goes on.

After Joe died in 2009，Misty slept on his pillow.

    I'm grateful一to a point. The truth is, after years of balking, I've come to enjoy m' walks with Misty. As I watch her chase after a squirrel, throwing her whole being into the here-and-now of an exercise that has never once ended in victory, she reminds me, too, that no matter how harsh the present or unpredictable the future , there's almost always some measure of joy to be extracted from the moment.

    Throughout the past few years, I have tried to give myself to others. I have bounced around to find where I truly fit in. I found my place while I stayed in Guatemala, an orphanage(孤儿院), with the children living there. Through hearing many stories of their lives, I was moved to tears and started question my living ways and gave up everything that wasn't essential: makeup and any other sort of luxury(奢侈品). I lived like they did. It was the most relaxing feeling in the world.

    When at Nuestros Pequenos Hermanos, we were given the task of creating a pig pen. At first, I thought it should be easy. After arriving at the area where the pig pen should be, we saw a hill. We were told to uproot the weeds as well as level the entire area. Looking at it, we felt 'it would be impossible. On my own faith journey, I have felt this type of doubt before. The “hole”, as we referred to, is a symbol of my faith journey. It appeared to be an obstacle I could not overcome, but in the end I completed it with efforts. I feel this pig pen wasn't easy to create but was so rewarding to give.

    I've always struggled to be on a journey of faith, but I've never completely stepped foot onto the path until Guatemala. I've always tried to open my heart to everyone around me and give them my love. I feel as though I cut open my heart and share every bit of love 'I had with these orphans. There is one orphan named Ceto who will always remain very close to my heart. In Guatemala, I sponsor with thirty dollars a month, but it doesn't seem enough. I'll return there next summer and give more of my love for a whole month.

    When it was time to leave, I looked out of the window and saw not just ordinary children. Overall, the most significant accomplishment I made in Guatemala was stepping towards my own faith journey and not looking back.

    Australian electronics and homewares retailers are preparing for the invasion (涌入) of American giant Amazon, but some have decided to take the fight up to the online-based store when it comes to local shores.

    Last week, Amazon confirmed its rapid Australia expansion by announcing that it was searching for a site to build its “fulfillment center”—a large warehouse(仓库)for storing and shipping goods purchased online—but local retailer, including one of Harvey Norman's founders Gerry Harvey, have said they will make it hard for Amazon to succeed in Australia.

    Harvey Norman sells electronics, furniture and bedding—all markets in which Amazon hopes to hold a stake, but Harvey has said that he will happily go toe-to-toe with the American behemoth to hold his ground in the Australian market.

    “In America and other parts of the world, they have just demolished (彻底打败) other retailers, no question about that, and they send a lot of retailers broke,” Harvey told News Corp on Monday. “There is no question they have one ambition and like Attila the Hun, or Alexander the Great, they just want to demolish everything in front of them and then at the end of the day claim to be victorious and make their own rules. So this is a company that is extraordinary by any measure and challenges every rule that has ever been written about a business.”

    Some analysts have said that Amazon could take in as much as 3 billion U. S. dollars in sales in its first five years in Australia (around I percent of the total 225 billion U.S. dollar market), but Harvey has refuted those claims, saying that local retailers would be putting up “one hell of a fight” when Amazon launches is main retail services in Australia. “We will be over there fighting them like no American retailer has ever fought them,” he said. “Any price that they put we will beat or equal.”

    Meanwhile, Harvey's thoughts were backed up by the former CEO of supermarket chain Woolworths. Roger Corbett, who said Amazon would struggle to keep its lower wages and claims of lightning fast delivery to rural parts when it opens in Australia. “Amazon will have an impact on the market place, but they are coming into an already very competitive market,” he told News Corp.

    The Trans-Siberian Railway is a single train line that crosses nearly the complete length of Russia, from Moscow to Vladivostok. It covers a total of 5,772 miles, running from Europe to Asia. Unlike the longest flight in the world, which just began transporting passengers in 2018, the Trans-Siberian Railway started its business in 1916.

    Anyone who has taken this long journey, or even just part of it, will tell you that it travels at a rather slow speed, passing through some amazing, remote areas of Russia. You don't have to make the full journey without stopping. Instead, you're suggested to get off where there are attractive views, since it stops in some pretty fantastic places. But you certainly can take the full journey non-stop. If you do, the trip will take about 144 hours—six full days!

    You can book tickets with travel agencies. You can also make the booking online and tickets will be sent to your hotel or personal address. Children under 4 years old accompanied by adults can travel free, but cannot take up a seat. A child ticket needs to be bought if you want to get a seat for the child.

    There are longer railway services in the transportation world, but only one of them is a passenger line as some longer routes transport goods, not travelers. This railway may not be the fastest or the most modern, but it's clearly still an important player in the transportation world!
