请阅读Passage 1。完成第小题。Passage 1Social 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 customary and undisputed.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. For example, it comes more readily in human relations on a continuous scale rather than one with sharp difference. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities,becauseof thesharpdifferencein appearance between them and their white counterparts.The passage is mainly discussing__________.查看材料

But what should I do to celebrate my 60th birthday? What else, but a journey at the opposite end of the world, Antarctica. I began my almost 400-mile journey on November 1st, 1997. I walked and skied alone. My dog team were not with me to pull my sled. Another journey of challenge and danger was about to begin.The first days the weather was very good. The wind was icy but not very strong and there was bright sunshine 24 hours a day. But changes were just around the comer. On the third day I was struggling through stormy weather and during the next week the wind grew stronger and I found myself spending a whole day in my tent.I had travelled only two hours one day when the winds increased so much that I had to put my tent up before the winds became too strong. Within a few minutes the winds increased to a howling storm that threatened to blow me and my tent away, but none of that happened.On November 12th the storm died down. It was my birthday and I wanted to make that day special. I thawed a frozen cake over my fire, placed a candle on the top, lit it and sang "happy birthday" to me, at the top of my voice.A few days later, I was moving forward over a slope that seemed safe when suddenly without warning my worht dropped out from under my skis. I had fallen into a hole and was hanging on the ropes tied to the sled. A piece of ice fell down and I never heard it land. The bottom was a few hundred feet below. I used to practice self rescue many times in the mountains where I live and carefully began climbing out. It took a long time but I finally got out. I was thankful for all the training I had had.I was in good health and all of my equipment was working well. I was so optimistic that I decided that the next day, the 22nd day of. the expedition, I would increase my workday to 12 hours.The next morning I had a bad accident with the sled and hurt my leg. I couldn't stand on my left leg and my head was woozy from hitting the ground. But I knew that I had to get up. Lying on the ice, I would soon die. I struggled to my knees knowing that somehow i had to put my tent up for shelter. On hands and knees I got the tent up and dragged my sleeping bag into the tent and lay down out of the cold wind.I had to make a decision. Wait to get better or give up? I had to think of my family, which is very important to me, and do the right thing. I did so without regret. I had met the challenges of solo travel in an extreme climate. It is an experience I shall never forget and shall value for the rest of my life.
