It was probably around 3,000 years ago that people first began making things to help them measure the passage of time. Having noticed that shadows move around trees as the sun moves across the sky, someone drew a circle and put a stick in the center. As the sun passed overhead, people could tell which part of the day it was by noticing which mark on the circle the shadow fell across. These circles were called “sundial(日晷)”. Later, they were made of stone and metal to last longer. Of course, a sundial did not work at night or on cloudy days, so men kept inventing other ways to keep track of time. The hourglass(沙漏) came into use later. An hourglass is a glass container in which sand moves slowly from the top half to the bottom in exactly one hour. The hourglass is turned over every hour so the sand could flow again. One of the first clocks with a face and an hour hand was built for a king of France and placed in the tower of his palace. The clock did not show minutes or seconds. Since there were no planes or trains to catch, people were not worried about knowing the exact time. Today, scientists have invented clocks that tell the correct time to a split second. Many electric clocks are often made with built-in radios, which can sometimes be set to turn on automatically. Thus, instead of an alarm ringing in your ear, you can hear soft music playing when it is time to get up. Some clocks will even start the coffee maker!
Questions 26 to 29 are based on the passage you have just heard.
26. When did people begin to measure the passage of time?
27. How often will an hourglass be turned over?
28. Why didn’t the first clocks have second and minute hand?
29. What can a modern electric clock do besides telling the time according to the passage?
选项
A、People were not so worried about the exact time.
B、People didn’t know how to make them.
C、The king didn’t want it.
D、There was no plane or train at that time.
答案
A
解析
因果关系题。浏览选项可知,四个选项分述了不同的意思,可能考查原因。文章提到最初的钟表是为一位法国国王制造的,只有表盘和时针。钟表没有分针和秒针是因为there were no planes or trains to catch(那时没有飞机或者火车要赶),因此人们不需要知道确切的时间,故选A。
