Coal, oil, natural gas, and all other fuels are stored energy from the sun. Some was collected by this season's plants as carbon compounds. Some was stored by plants and trees ages ago. Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power. Light transmits only the energy that comes from the sun's outer layer, and much of this energy that is directed towards the earth never arrives. About nine tenths of it is absorbed by the atmosphere of the earth. In fact, the earth itself gets only one half millionth of the sun's entire output of radiant energy.
The sun is the source of all of the following EXCEPT______.
A.gasoline
B.natural gas
C.atomic power
D.animal fat
Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.
If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.
The best title for this passage is______.
A.The Earth Weight
B.Weight in Space
C.Changing Weight on the Earth
D.Weight on and off the Earth

Lilian Hanson, a college students, expects to graduate in about two years. What makes Mrs. Hanson different from her classmates is her age—73 years. She has been studying at college, a few courses at a time, for 27 years.

Jim had a twin brother who died when he was nine years old. By the time he was 16, his mother and father were also dead. Jim then went to a special school in Pennsylvania for Native American children. There, he learned to read and write and also began to play sports. Jim was poor, so he left school for two years to earn some money. During this time, he played on a baseball team. The team paid him only $ 15 a week.
