Passage Two
| Although the American civilization took over and replaced the frontier over a century ago, the heritage of the frontier is still evident in the United States today. Many people are still fascinated by the frontier because it has been particularly important in shaping American values. For many years, the frontier experience was romanticized in popular movies and television shows that featured cowboy heroes fighting Indian villains. Little attention was given to the tragic story of what really happened to Native Americans. Today, most Americans are more aware of the darker side of the settling of the continent, when thousands of Native American Indians were killed, their lands were taken, and much of their culture was destroyed. The American frontier consists of the relatively unsettled regions of the United States, usually found in the western part of the country. Here, both land and life were more rugged and primitive than in the more settled eastern part. As one frontier area was settled, people began moving farther west into the next unsettled area, sweeping aside the Native Americans as they went. By settling one frontier area after another, Americans moved across an entire continent, 2 700 miles wide. They came to believe that it was their destiny to control all the land, and eventually they did. The Native Americans were given small portions of land called reservations to control, but the United States government broke many promises and created much misery for the Indian nations. Recently, Americans have come to a more balanced view of the settling of the West. However, many Americans still see many aspects of the frontier, its people and their beliefs, as good, inspiring examples of traditional American values in their original and purest form. How did the frontier movement, which lasted more than two centuries, help to shape these basic American values To be sure, the frontier provided many inspiring examples of hard work as forests were turned into towns, and towns into large cities. The competitive race for success was rarely more colorful or adventurous than on the western frontier. Individualism, self-reliance, and equality of opportunity have perhaps been the values most closely associated with the frontier heritage of America. Throughout their history, Americans have tended to view the frontier settler as the model of the free individual. In the United States, where freedom from outside social controls has traditionally been valued, the frontier has been idealized, and it still serves as a basis for a nostalgic view of the early United States, a simpler time that was lost when the country became urbanized and more complex. |
By saying "Recently, Americans have come to a more balanced view of the settling of the West. " (Para. 3) the author means ______ .
A．Americans have recognized both the significance and the darker side of the settling of the West
B．Americans have realized the settling of the West provided both good and bad examples of traditional American values
C．Americans have realized that some of the traditional basic values should be reconsidered
D．Americans are more aware that the shaping of American values was influenced by both the frontier experience and many other factors

背景资料：
某施工单位承接了两栋住宅楼，总建筑面积65000m2，均为筏板基础（上反梁结构），地下2层，地上30层，地下结构连通，上部为两个独立单体，呈“一”字形设置。设计形式一致，地下室外墙南北向距离40m，东西向距离120m。
施工过程中发生以下事件：
事件一：项目经理部首先安排了测量人员进行平面控制测量定位，很快提交了测量成果，为工程施工奠定了基础。
事件二：项目经理部编制防火设施平面图后，立即交由施工人员按此进行施工。在基坑上口周边四个转角处分别设置了临时消火栓，在60m2的木工棚内配备了2只灭火器及相关消防辅助工具。消防检查时对此提出了整改意见。
事件三：基坑及土方施工时设置有降水井。项目经理部针对本工程具体情况制订了《***工程绿色施工方案》，对“四节一环保”提出了具体技术措施，实施中取得了良好效果。
事件四：结构施工至12层后，项目经理部按计划设置了外用电梯，相关部门根据《建筑施工安全检查标准》JGJ59—2011中《施工升降机检查评分表》的内容逐项进行检查，通过验收准许使用。
事件五：回填土施工时正值雨季，土源紧缺，工期较紧，项目经理部在回填后立即浇筑地面混凝土面层。在工程竣工初验时，该部位地面局部出现下沉，影响使用功能，监理工程师要求项目经理部整改。
事件五中，导致地面局部下沉的原因有哪些？在利用原填方土料的前提下，给出处理方案中的主要施工步骤。
