15.How could we tell time if there were no watches or clocks anywhere in the world?The sun was probably the world's first"clock",except in the far north,where the Eskimos (爱斯基摩人) live.There,it's dark most of the winter,and light most of the summer.But in most of the world,people have used the sun for a clock.Even today,if you don't have a clock,you still know that when the sun shines,it's day,and when it's dark,it's night.The sun can also tell you if it's morning,noon,or afternoon.
People who live near the sea can tell time from the tides.In the daytime,for about six hours,the water rises higher and higher on the beach.And then it goes down and down for about six hours.The same thing happens again at night.There are two high tides and two low tides every 24hours.
Seamen on a ship learn how to tell time by looking at the moon and the stars.The whole sky is their clock.
In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing.In these places the wind can be the clock.
A sand clock is an even better clock.If you had fine dry sand in a glass shaped like the one in the picture,you would have what is called an hourglass.The sand in the hourglass goes from the top part to the bottom part in exactly one hour.When the hourglass is turned over,the sand will take another hour to go back again.

分析 在没有手表的情况下,我们如何才能知道具体的时间?
太阳是地球上最早的钟表.太阳不仅可以告诉你黑天白夜,还能告诉你是早晨、中午还是傍晚.
住在海边的人可以根据潮汐来判断时间.在白天,大约6个小时,会涨潮,海面会越来越高,随后会退潮,大约也是六个小时,在夜间也会发生这样的循环,也就是在24小时之内,会出现两次涨潮、两次退潮;
渔民通过观看星星和月亮来获取时间.
某些地区的人们可以通过风来确定时间.
沙漏也可以告诉我们时间.
解答 51.C.细节理解题.根据文中的内容,文中介绍了五种判断时间的方法,依次是太阳(The sun was probably the world's first"clock",)、潮汐(People who live near the sea can tell time from the tides.)、星星和月亮(Seamen on a ship learn how to tell time by looking at the moon and the stars.)、风(In these places the wind can be the clock.)和沙漏(A sand clock is an even better clock.)
52.D.细节理解题.根据The sun was probably the world's first"clock",except in the far north,where the Eskimos (爱斯基摩人) live.可知,太阳对于我们是首先用到的钟表,但是除了爱斯基摩人所住的地方,原因就是There,it's dark most of the winter,and light most of the summer.,这个地方的冬天是黑暗的,夏天是有太阳的,也就是存在极昼和极夜,这种情况太阳是派不上用场的,因此答案为D.it has long dark winters and long light summers
53.B.词义猜测题.根据划线词所在的段落,讲述的主要是用海中发生的tide来判断时间,根据段落的描述以及我们生活中的观察,海洋中的涨潮和退潮是有规律的,因此这里的tide是潮汐;
54.B.细节理解题.根据文章中的内容,主要讲述的就是判断时间的方法,因此这篇文章最有可能出现在报纸中的科学板块,因此答案为B.Science.
55.A.文章主旨题.文章讲述了五种判断时间的方法,因此文章的主旨就是A.Different Ways to Tell Time,判断时间的不同方法.
