One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter Island, which was almost uninhabited when it was discovered on Easter Day in 1722 by a Dutch captain, is the most distant island in the world covered with hundreds of giant statues, each weighing several tons and some standing more than 30 feet tall.

Who built these statues and why and how did they get there? Nobody knows the answer for sure.

One theory suggests that Easter Island was first inhabited by Polynesians, who traveled thousands of miles in their canoes（独木舟）in 400 A.D. However, the ocean currents（洋流）which carried them there would not take them back, so that they could not leave.

The statues appear to have been made out of the top edge of the walls of a volcano on the island. Then, it may have been rolled or dragged down to the foot of the volcano(火山). Then, it was stood upright（直立）and ropes were tied around it, which was made to act as a pulley（滑轮）. Over a period of months, a statue could be walked for miles down to the ocean. Finally, it was placed in line with other statues, all of them looking towards the center of the island.

This process was difficult. If a statue fell over, it was too heavy to be pulled upright again, so the islanders went back and carved another statue.

The population of Easter Island must have reached 11,000. Later, the resources of the island were used up and people began fighting and eating each other. Work on the statues stopped and the statues were knocked over. When the first Europeans finally arrived on the island, most of these people had died out.

(四) 承包人承担某堤防工程，工程项目的内容为堤段I(土石结构)和堤段Ⅱ(混凝土结构)，合同双方依据(堤防和疏漏工程施工合同范本)签订了合同，签约合同价为600万元，合同工期为120d。合同约定：(1)工程预付款为签约合同的10%；当工程进度款累计达到签约合同价的60%时，从当月开始，在2个月内平均扣回；(2)工程进度款按月支付，保留金(质量保证金)在工程进度款中按5%预留。经监理机构批准的施工进度计划如下图所示。

由于发包人未及时提供施工图纸，导致“堤段Ⅱ混凝土浇筑”推迟5天完成，增加费用5万元。承包人在事件发生后向发包人提交了延长工期5天，补偿费用5万元的索赔申请报告。 根据工程量统计表绘制的工程进度曲线如下。

监理机构确诊的1-4月份的工程进度款见下表。
