Ways to Deal with the Problem of Energy
There are different ways in which people try to deal with the problem of energy.One way is the greater production of common energy sources,such as coal,oil and gas.The trouble with these sources,however,is that they are not renewable.
Another way is energy conservation(节能),which means using energy more efficiently.In some very cold countries people build special houses to save energy.They place materials between the inside and the outside of the walls of the house to keep the cold out and warmth in.The house is heated by the lights,the body heat of the people and the other equipment in it.
Finally,renewable energy sources are used even though they are often expensive to develop.One form of these is geothermal energy.In certain parts of the world the temperature of the earth increases thirty degrees centigrate with each kilometer down.At six kilometers,therefore,it rises to nearly 200degrees.To get the heat,water is pumped down into the rocks and back up to the surface.Heat from the earth is already used in certain countries.
73.The writer tells about “the special houses”because they______.
A.show the excellent skills of the builders
B.serve as an example of the energy conservation
C.are heated by different sources of energy
D.are warmer than other types of energy
74.The underlaned words”geothermal energy”in the third paragraph mean____.
A.renewable source B.underground source
C.heat inside the earth D.temperature of the earth
75.At a place where the surface temperature is 15degrees centigrade,how deep do you have to dig so as to get a temperature of 75 degrees centigrade?
A.One km. B.Two km. C.Three km. D.Four km.

Many reasons can explain why football is so popular. All around the world, millions play the sport and many more like to watch it. Some would say that the simplicity of the game is the main reason for its popularity, but that can’t be true as, this way, marathons or races would be the most popular sports in the world. In fact, the most popular sport in the world is football.
The main reason for the popularity of any sport is the room for creativity inside the sport. Football has plenty of room for creativity as it enables players to use their bodies in unique ways to get hold of the ball and score while at the same time keeping the other team from scoring. In addition to this, the rules ensure that the game is clean and fair, thus encouraging new players to play it.
Another reason is that this game doesn’t require expensive equipment. All the kids in poor developing countries like playing it as all they need to play it is a ball and an empty playground, and that would ensure a quality time for a group of kids who want to enjoy their time. The Federation International de Football Association (FTFA) knows this fact and is always trying to keep the rules and regulations applicable for poorer countries.
For fans of the sport, it is very entertaining to watch the skills and talents of the players in professional matches. The outcome of a match can easily change in the dying moments of a game. Some matches are even better than watching a thriller, because you really have no idea what the result of the match will be.
