    Many of the problems we face today are not so new as we think they are．And some of our modern solutions are not so new, either．The problem of energy shortages and the solution of using solar energy go back at least to early Greek cultures．The climate in the coastal areas of Greece 2,500 years ago was characterized by cool winters, much as it is today．At that time, the Greeks heated their homes with small, charcoal-burning heaters．In other words, wood (which is used to make charcoal) was their primary source of energy．However, by the fifth century BC fuel shortages had become common because, in many parts of Greece, the firewood in the forests had been depleted．Once the supply of firewood from the local forests ran out, people began to use the wood from olive groves as fuel．But this solution had its own problem．It reduced the olive crop, a valuable resource to the Greeks．By the fourth century BC, the city of Athens banned the use of olive wood for fuel．Wood had to be imported from farther and farther away, making it more difficult to obtain and more expensive to use．About this time the Greeks began to build their houses facing south, so that the low sun in winter could penetrate and help heat the interiors．Excavations of ancient Greek cities suggest that large areas were planned so that individual homes could take maximum advantage of passive solar energy．

C．used up
D．discovered

5、 回答题
Never laugh at a snow covered mountain! Laughter and yelling, during the avalanche season, can cause a deadly pile of snow．Huge snow slides are most common in mountains where there are steep slopes that are well buried in snow and ice．The snow builds up slowly and lands very softly．This can create a very touchy, unstable situation．Tons of snow may be held up by only the friction between snowflakes．The deep snow is like a house of cards．The slightest movement can cause it to fall．As soon as something slips, this great mass of snow will come crashing down the mountainside．Slides may be started by sound vibrations．They may also be started by the weight of wet, melting snow．Once an avalanche has been triggered, the cause no longer matters．Moving down a steep slope, it picks up great speed and added snow．Some avalanches travel as fast as two hundred miles per hour．The force of an avalanche will mow down anything in its path．Whole houses have been swallowed up by these fast-paced piles of snow．The wind that is caused by an avalanche is almost as destructive as the snow itself．Winds from an avalanche have been known to travel as fast as those of a tornado．So, when approaching a thickly snow covered mountain, speak softly!

Avalanches can be started by________
A．falling snow
B．the wind
C．loud sounds
D．friction between snowflakes
