单选题Daylight Saving Time begins on Monday, April 3, 2005. People in most parts of the United States will turn their clocks ahead one hour. The official(正式的) time to turn your clock ahead is early in the morning, April 3. Two a.m. becomes three am. Sunday will have only 23 hours. (Most people change their clocks before they go to sleep Saturday night.) In the fall, people turn their clock back an hour. This saying helps people remember which way to turn the clock: "Spring ahead; fall back." ( Spring and fall each have two meanings here.) We use Daylight Saving Time in order to save electricity (电). We need one less hour of light from electricity each day in the summer. Arizona, Hawaii, and parts of Indiana do not use Daylight Saving Time. Not every country uses Daylight Saving Time, either. Countries near the equator(赤道) have no reason to use Daylight Saving Time. Their hours of daylight and darkness are always nearly the same. There is no Daylight Saving Time in Japan, China, or India. Countries south of the equator have quite different seasons. They are ending their Daylight Saving Time now.
