Petroleum products, such as gasoline, kerosene, home heating oil, residual fuel oil, and lubricating oils, come from one source - crude oil found below the earths surface, as well as under large bodies of water, from a few hu
6、ndred feet below the surface to as deep as 25,000 feet into the earths interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those producing oil. Pressure at the source or pumping forces crude oil to the surface. Crude oil wells flow at va
7、rying rates, from ten to thousands of barrels per hour. Petroleum products are always measured in 42-gallon barrels. Petroleum products vary greatly in physical appearance: thin, thick, transparent or opaque, but regardless, their chemical composition is made up of two elements: carbon and hydrogen,
8、 which form compounds called hydrocarbons. Other chemical elements found in union with the hydrocarbons are few and are classified as impurities. Trace elements are also found, but these are of such minute quantities that they are disregarded. The combination of carbon and hydrogen forms many thousa
9、nds of compounds which are possible because of the carious positions and joinings of these two atoms in the hydrocarbon molecule.The various petroleum products are refined from the crude oil by heating and condensing the vapors. These products are the so-called light oils, such as gasoline, kerosene
10、, and distillate oil. The residue remaining after the light oils are distilled is known as heavy or residual fuel oil and is used mostly for burning under boilers. Additional complicated refining processes rearrange the chemical structure of the hydrocarbons to produce other products, some of which

Heating and condensation produce the various products.C. Chemical separation is used to produce the various prod
14、ucts.D. Mechanical means such as the centrifuge are used to produce the various products.正确答案：B 4). Mechanical means such as the centrifuge are used to produce the various A. Expansion of the hydrocarbons.B. Pressure and pumping.C. Vacuum created in the drilling pipe.D. Expansion and contraction of
15、the earths surface.正确答案：B 5). Which of the following is NOT listed as a light oil?A. Distillate oil.B. Gasoline.C. Gasoline.D. Kerosene. 正确答案：C 2. People became quite illogical when they try to decide what can be eaten and what cannot be. If you lived in the Mediterranean, for instance, you would consider octopus a great delicacy. You would not be able to understand why some people find it repulsive. On the other hand, your stomach would turn at the idea of frying potatoes in animal fatthe nor
