听力原文： The water clock was an ancient clock. It could be used on cloudy days, at night, and indoors. Such clocks were probably first used in Egypt about 2000 BC. They were also used for many years in Arabia, India, China, and all of Europe.
The simplest water clock needed just two parts—a small bowl and a large bowl. The small bowl had a tiny hole in the bottom; the large bowl was divided into equal parts and marked by lines. Water was poured into the small bowl, and it fell slowly down into the large bowl in tiny drops. Usually it took an hour for the water to rise from one line to the next in the large bowl.
A beautiful water clock was made in Persia over a thousand years ago. It was presented as a gift to the Emperor of France.This water clock could be heard as well as seen. The dial of the clock could heard as well as seen. The dial of the clock was made up of twelve doors, each representing an hour. At twelve o'clock, twelve tiny horsemen came out and shut all the doors.This was probably one of the first striking clocks.

听力原文： I'm sure almost every one of you looked at your watch or at least a clock before you came to class today. Watches and clocks seem as much a part of our life as breathing or eating. And yet did you know that watches and clocks were scarce in the United States until the 1850s？ In the late 1700s, people didn't know the exact time unless they were near a clock. Those delightful clocks in the squares of European towns were built for the public. Alter all, mast citizens simply couldn't afford a personal timepiece. In the 1800s in Europe and the United States, the main purpose of a watch, which by the way was attached to a gold chain, was to show others how wealthy you were. The word "wristwatch" didn't even enter the English language until nearly 1900. By then the rapid pace of the industrialization in the United States meant that measuring time had become essential. How could the factory worker get to work on time unless he or she knew exactly what time it was？ Since efficiency was now measured by how fast the job was done, everyone was interested in time. And since industrialization made possible the manufacture of larger quantities of goods, watches became fairly inexpensive. Furthermore, electric light kept factories going around the clock. Being "on time" had entered the language and life of every citizen.

A．The development of individual time pieces.
B．Reasons for increased productivity.
C．How wristwatches are manufactured.
D．The industrialization of the United States.
听力原文： Twice a year, all the clocks in the United States are changed by one hour. In the spring, clocks are moved ahead an hour. This is called daylight savings time. In the fall, clocks are set back an hour to standard time. People remember how to change their clocks by remembering this saying: Spring forward, fall back. It seems Benjamin Franklin was the first person to propose the idea of daylight savings time back in the 1790s. At the time, people thought he was joking. They couldn't believe he was serious. Many years later, during World War I, people realized what an innovative idea he'd had. In the spring and summer, the sun rises earlier. By moving the clock ahead, people can take advantage of the extra daylight and save energy. Energy is an important resource, of course, especially during wartime. The United States operated on daylight savings time during World War I and again during World War II. After that some parts of the country observed daylight savings time and some didn't. Beginning and ending dates varied from place to place. This confusion ended in 1966, when the Congress passed the Uniform. Time Act, standardizing the process and making daylight savings time a federal law. Since then, some lawmakers have proposed that the United States go to year-round daylight savings time.

A．The Uniform. Time Act.
B．The role of daylight savings time in wartime.
C．Ways to save energy.
D．The history of daylight savings time.
