Passage OneQuestions 21 to 25 are based on the following passage.The communication process begins with the formulation of an idea or the selection of information by its sender. The sender then encodes the idea into symbols, thereby creating a message, which is subsequently transmitted (传送) through one or more channels (e.g., speaking, writing, or electronic media). It is at this point that the receiver decodes(解码) and attaches meaning to the message. If effective communication has occurred, the receiver will understand the idea and information as the sender intended. Unfortunately, the potential for physical and perceptual noise, which can distort the intended message of the sender, is present at every stage of the process. Fortunately, noise can be overcome through effective feedback(反馈), a response from the sender that allows misunderstandings to be identified and resolved. Two way communication-communication that allows feedback-is almost always moreeffective than one way communication.Each of the steps in the communication process has potential problems that can impede(妨碍) effective communication. During encoding, the primary difficulty usually results from the nature of symbols and the semantic (语义) variation in their meanings. In addition to these distortions, the sender must also be aware of nonverbal messages that might distort the message. This awareness is important because research has shown that nonverbal messages are given greater weight by the receiver when decoding and attaching meaning to the message. The effectiveness of encoding will be increased if the sender develops empathy (感情移入) for the receiver and is aware of his or her own feelings and emotions. The key to effective transmission of the message is choosing the mostA. Communication ProcessB. CommunicationC. Effective CommunicationD. Transmission of22. Two way communication is more effective than one way communicationbecause ________.A. it allows feedbackB. it can distort the intended message of the senderC. the sender is aware of the nonverbal messages that might distort the messageD. none of the above23. Unless the receiver understand the idea and information as the senderintended, ________.A. effective communication can be achievedB. effective communication cannot be achievedC. the communication process will not endD. both B and C24. Problems that might impede effective communication are causedby________.A. the nature of symbolB. the semantic variation in their meaningsC. nonverbal messagesD. all of the above25. Which of the following is critical to effective communication?A. Creating a message.B. Developing empathy for the receiver.C. Overcoming noise through effective feedback.D. Choosing the most appropriate channel or channels of media.Passage TwoQuestions 26 to 30 are based on the following passage.Scientists claim that air pollution causes a decline in the world's average air temperature. In order to prove that theory, ecologists have turned to historical data in relation to especially huge volcanic eruptions. They suspect that volcanoes affect weather change that areOne source of information is the effect of the eruption of Tambora, a volcano in Sumbawa, the Dutch East Indias, in April 1815. The largest recorded volcanic eruption, Tambora threw 150 million tons of fine ash into the stratosphere(平流层). The ash from a volcano spreads worldwide in a few days and remains in the air for years. Its effect is to turn incoming solar radiation into space and thus cool the earth. For example, records of weather in England show that between April and November 1815, the average temperature had fallen 4.5 . During the next twenty four months, England suffered one of the coldest periods of its history. Farmers' records from April 1815 to December 1818 indicate frost throughout the spring and summer and sharp decreases in crop and livestock markets. Since there was a time lag(滞后) of several years between cause and effect, by the time the world agricultural commodity community had deteriorated, no one realized the cause.Ecologists today warn that we face a twofold menace. The ever present possibility of volcanic eruptions, such as that of Mr. St.Helens in Washington, added to man's pollution of the atmosphere with oil, gas, coal, and other polluting substances, may bring us increasinglycolder weather.26. It is believed that the earth gets colder when ________.A. volcanoes eruptB. the air is polluted by modern manC. the rays of the sun are turned into spaceD. all of the above27. The effects of Tambora's eruption were ________.A. felt mainly in the Dutch East IndiasB. of several day's duration worldwideC. evidence of pollution's cooling the earthD. immediately evident to the world's scientists28. The cause of cold weather in England from 1815 to 1818 was ________.A. decreased crop and livestock productionB. volcanic ash in the atmosphereC. pollution caused by the Industrial RevolutionD. its proximity to the North sea29. No one realized the cause of the deterioration of the world agricultural commodity market because ________.A. there was a long delay between cause and effectB. the weather is beyond our comprehensionC. weather forecasts were inaccurateD. ecologists didn't exist until modern times30. If, as some scientists predict, the world ends in ice, what might be the cause?A. Modern man's pollution of the air.B. Volcanic eruptions.C. Obliteration(破坏) of solar radiation.D. All of the above.Passage ThreeQuestions 31 to 35 are based on the following passage.The great advance in rocket theory 40 years ago showed that liquid fuel rockets were far superior in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. However, during the last decade, large solid fuel rockets with solid fuels about as powerful as liquid fuels have made their appearance, and it is a favorite layman's(外行) question to inquire which one is “better.” The question is meaningless; one might as well ask whether a gasoline or a diesel engine is “better.” It all depends on the purpose. A liquid fuel rocket is complicated, but has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited(重新点火) when desired. In addition, the thrust can be made to vary by adjusting the speed of the fuel pumps. A solid fuelrocket, on the other hand, is rather simple in construction, though hard to build when a really large size is desired. But once you have a solid fuel rocket, it is ready for action at very short notice. A liquid fuel rocket has to be fueled first and cannot be held in readiness for very long after it has been fueled. However, once a solid fuel rocket has been ignited, it will keep buming. It cannot be stopped and reignited whenever desired (it could conceivably be stopped and reignited after a pre calculated time of burning has elapsed) and its thrust cannot be varied. Because a solid fuel rocket can be kept ready for a long time, most military missiles employ solid fuels, but manned spaceflight needs the fine adjustments that can only be provided by liquid fuels. It may be added that a liquid fuel rocket is an expensive device; a large solid fuel rocket is, by comparison, cheap. But the solid fuel, pound per pound, costs about 10 times as much as the liquid fuel. So you have, on the one hand, an expensive rocket with a cheap fuel and on the other hand a comparatively31. The author feels that a comparison of liquid and solid fuel rockets shows that ________.A. neither type is very economicalB. the liquid fuel rocket is bestC. each type has certain advantagesD. the solid fuel rocket is best32. The most important consideration for manned space flight is that therocket be ________.A. inexpensive to constructB. capable of lifting heavy spacecraft into orbitC. easily controlledD. inexpensive to operate33. Solid fuel rockets are expensive to operate because of their________.A. sizeB. burning timeC. fuelD. complicated engines34. Which of the following statements is not characteristic of liquidfuel rockets?A. The fuel is cheap.B. They are cheap to build.C. They can be stopped and reignited.D. They must be used soon af35. Which of the following statements is a possible disadvantage of solidfuel rockets?A. They are complicated.B. They are uneasily adjusted.C. They are expensive to construct.D. They cannot be ready for action with little time for preparation.PART TWOⅣ. Word Spelling (10 points, 1 point for two items ) 将下列汉语单词译成英语。
