从题中所给的A、B、C、D四个选项中,选出最佳答案.
The idea of summer time started with an American named Benjamin Frankin(1706-1790).He explained how a lot of the money spent on candles used for light (this was before electricity)could be saved if everyone woke up earlier and went to bed earlier.
Even though Frankin's idea had a clear meaning,most people didn't want to get up earlier than they had to.Who would?
It was not until 1907 that an Englishman names William Willet came up with a way to "make"the sun set late.His idea was to turn clocks forward by 20minutes on each of the four Sundays in April,for a total of 80 minutes.
William's idea was laughed at,at first.But when World War I started in1914,many countries decided they had to save energy for the war,and they put Willet's idea into use.
Summer time has other uses.The more time you spend outside playing,the less time you are spending in front of the computer or TV.These things also use energy.
However,summer time sometimes causes problems.For example,China used it in 1986,but it was stopped in 1991.That was because the temperatures are quite different from North to South and time from East to West.
If the people from northwest part of China use summer time,sometimes they have to get up to work when it is not very bright outside.That will cause some trouble for them.
Still,most parts of the world do have summer time,and most people look forward to the extra hour of evening light.
