52. They started work when the Sun came up in the east. At noon, when the Sun was very high, they ate and rested. When the Sun disappeared in the west, they went to bed.
Today, we know that the Earth turns on an imaginary line called an axis (地轴). The time it takes for the Earth to make one complete turn is called a day. 53. There are 24 hours in a day. There are 60 minutes in an hour. And there are 1,440 minutes in one day!
54. The Earth travels around the Sun. The time it takes for the Earth to go around the Sun once is called a year. There are 12 months in one year.
Thanks to clocks and calendars(日历), we can measure(测量) time very easily. 55.
A. We measure time by other movements, too.
B. Before clocks, people told the time by watching the Sun move across the sky.
C. From morning until night, clocks help us to plan our day.
D. A day is divided into hours, minutes, and seconds.
E. However, it is the movement of the Earth that really allows us to measure time.

解析
【分析】本题为英语七选五阅读题，需梳理文章围绕“时间的测量”的逻辑脉络，结合上下文的指代关系、语义衔接及语境匹配来选择答案：51空后“they”指代填空内容，需找能对应“告知事件起止”的事物；52空后描述古代人靠太阳作息，对应无时钟时的计时方式；53空前后围绕“一天”的定义及时长，需衔接时长单位的划分；54空前后涉及地球自转（一天）和公转（一年），需找涉及其他运动的表述；55空总结测量时间的本质，对应核心逻辑。
【解析】51. 后文“they”指代填空处的事物，选项C中“clocks”符合指代，且“help us to plan our day”与“when things begin and when they end”语义衔接，故选C；52. 后文讲述古代人随太阳位置作息，对应选项B“Before clocks, people told the time by watching the Sun”，符合语境；53. 前文定义“一天”为地球自转一周的时间，后文说明一天的时长单位，选项D“A day is divided into hours, minutes, and seconds”衔接前后内容，故选D；54. 前文讲地球自转形成“一天”，后文讲公转形成“一年”，选项A“measure time by other movements”对应不同的地球运动，符合逻辑；55. 前文提到时钟和日历方便测量时间，选项E“it is the movement of the Earth that really allows us to measure time”总结测量时间的本质，故选E。
【答案】51.C 52.B 53.D 54.A 55.E
【知识点】英语阅读理解（七选五）、语篇逻辑衔接
【点评】本题为七选五阅读题型，重点考查学生对文章语义连贯性、上下文逻辑关系的理解，需结合指代、语境匹配等技巧解题，属于中等难度的阅读题型。
