单选题Petroleum products, such as gasoline, kerosine, home heating oil, residual fuel oil, and lubricating oil, all come from one source ― crude oil found below the earth'' s surface, as well as under large bodies of water, from a few hundred feet below the surface to as deep as 25 000 feet into the earth''s interior. Sometimes crude oil is secured by drilling a hole through the earth, but more dry holes are drilled than those generating oil. Pressure at the source or pumping forces crude oil to the surface. 　　Crude oil wells flow at varying rates, from ten to thousands of barrels per. hour. Petroleum products are always measured in 42-gallon barrels. 　　Petroleum products are different in physical appearance: thin, thick, transparent or opaque, but their chemical composition is made up of only two elements: carbon and hydrogen, 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 thousands of compounds which are possible because of the various 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 light oils, such as gasoline, kerosine, and distillate oil. The residue remaining after the light oils are distilled is named 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 are used to upgrade and increase the octane rating of various kinds of gasoline.

单选题{{B}}Text 1{{/B}} I don't know how I became a writer, but I think it was because of a certain force in me that had to write and that finally burst through and found a channel. My people were of the working class of people. My father, a stone-cutter, was a man with a great respect and veneration for literature. He had a tremendous memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such a man would like. Nevertheless it was good poetry, Hamlet's Soliloquy, Macbeth, Mark Antony's Funeral Oration, Grey's Elegy, and all the rest of it. I heard it all as a child; I memorized and learned it all He sent me to college to the state university. The desire to write, which had been strong during all my days in high school, grow stronger still. I was editor of the college paper, the college magazine, etc, and in my last year or two I was a member of a course in playwriting which had just been established there. I wrote several little one-act plays, still thinking I would become a lawyer or a newspaper man, never daring to believe I could seriously become a writer. Then I went to Harvard, wrote some more plays there, became obsessed with the idea that I had to be a playwright, left Harvard, had my plays rejected, and finally in the autumn of 1926, how, why, or in what manner I have never exactly been able to determine. But probably because the force in me that had to write at length sought out its channel, I began to write my first book in London. I was living all alone at that time. I had two rooms -- a bedroom and a sitting room -- in a little square in Chelsea in which all the houses had that familiar, smoked brick and cream-yellow-plaster look.

单选题Space is a dangerous place, not only because of meteors(流星)but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation(辐射) from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage. Radiation is die greatest known danger to explorers in space. The unit of radiation is called" rem". Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage--a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的)children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation during the outward and return journeys. So far, no dangerous amounts of radiation have been reported, but the Apollo mission have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in space laboratory. Rugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.
