As long as the sun shines, the earth will not run out of energy. The sun pours more energy on earth than we can ever use. Most of that energy comes to us as heat and light. Energy from the sun is called solar energy.' n6 c7 D8 _+ H, K
Anything to do with the sun is called "solar". The word began with the Roman word for the sun and their god of the sun, who was called Sol. Solar energy is a safe kind of energy. It doesn't make pollution or have dangerous leftovers. That is why scientists and investors are experimenting with ways of harnessing（治理利用）the sun to do some of the jobs fossil fuels have been doing.5 v) F1 n% C6 A9 \4 P
But to make the sun do work like that, they have to solve some problems. They have to collect the sun's energy. Collecting sunshine is not easy, unless you are a plant. Sunshine is not easy to store, either. You can't fill a tank with it or put it in the wood box. You can not move it through a pipe or a wire. You can not just turn it on.

) C- p1 c5 V" p3 O1 `& EThe word "horsepower" was first used two hundred years ago. James Watt had made the world's first widely used steam engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring power.6 `5 I9 ?- c8 h- G) d8 @ i9 Y
Watt decided to find out how much work one strong horse could do in one minute. He called that unit one horsepower. With this unit he could measure the work his steam engine could do.0 N) N0 G' [! e/ i. c+ g; I
He discovered that a horse could lift a 3300-pound weight 10 feet into the air on one minute. His engine could lift a 33-pound weight 100 feet in one minute.
/ e; j, e, k& t Because his engine did ten times as much work as the horse, Watt called it a ten horsepower engine.

Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why? Because that is what they have been told all their life. But a new report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking.
/ t$ X9 S0 L& y! ^8 dThe report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, part of the National Academies. This organization provides scientific and technical advice to the government and the public.
' l; w* I) D; v, S; ~) F5 gThe report contains some general suggestions. The experts say women should get about two-point-seven liters of water daily. Men should get about three-point-seven liters. But wait － in each case, that is more than eight glasses.
2 R# s7 S- w" F8 r4 vThere is an important difference. The report does not tell people how many glasses of water to drink. In fact, the experts say it may be impossible to know how many glasses are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods. People do not get water only by forcing themselves to drink a set number of glasses per day. People also drink fruit juices and sodas and milk. They drink coffee and tea. These all contain water. 1 c7 j) \7 f$ v5 n S3 i
As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need two times as much water as others do.
