and many other factors must be considered.
196. Mathematics is very important in all branches of engineering so A . A. it is greatly stressed B. it is nearly stressed C. it is not stressed
197. Statistics deals with B . A. listening and speaking
B. gathering, classifying and using pieces of information
C. reading and writing
198. An important aspect of statistical mathematics is A . A. probability B. different factors C. variables
199. Which is the main meaning of the passage? B A. physics is very important in all branches of engineering B. mathematics is very important in all branches of engineering C. chemistry is very important in all branches of engineering
Passage Seven
Civil engineering projects are almost unique; that is, each has its own problems and design features. Therefore, careful study is given to each project even before design work begins. The study includes a survey both of topography and subsoil features of the proposed site. It also includes a consideration of possible alternatives, such as a concrete gravity dam or an earth-fill embankment dam. The economic factors involved in each of the possible alternatives must also be weighed. Today, a study usually includes a consideration of the environmental impact of the project. Many engineers, usually working as a team that includes surveyors, specialists in soil mechanics, and experts in design and construction, are involved in making these feasibility
23
studies.
200. Civil engineering projects are A A. almost always distinctive B. the similar C. alike
201. Each project __C_____ before design work begins A. may not be considered B. can?t be studied C. must be studied carefully
202. The study, which must consider not only structural features but also economic factors and possible alternatives or other choices, is called B . A. system engineering B. feasibility study C. structural design
203. Which of the following is true? A
A. today civil engineering project need consider the environmental impact of the project B. today the study about civil engineering project needn?t consider the environmental impact
of the project
C. today the study about civil engineering project needn?t consider the resource impact of the
project
Passage Eight
Clearing the site precedes all grading and most other construction operations. Site clearing in rural areas may sometimes merely require that glass, shrubs, and other plants or crops be removed. However, it sometimes can involve removing trees and tree stumps and disposing of the debris. The accepted procedure is to remove practically all vegetable matter from the original ground and from fill material, since, if allowed to remain; it may decay and leave voids that result in
24
settlement. Selective clearing in adjoining areas may at times be required. 204. According to the passage, which is the main topic? B A. excavation B. site clearing C. embankment
205. According to the passage, ____B___ is NOT be removed in rural areas. A. shrubs B. crops C. earth
206. If all vegetable remained, C . A. it may cause shortage of vegetable in the market B. the vegetable grow fast C. it may decay and leave voids
207. Sometimes it is required clearing A . A. adjacent areas B. far areas C. rural areas
Passage Nine
Vehicular safety design usually centers on protecting the driver and his passengers in case an accident occurs due to some other failure in the highway system. Examples of this type of design are safety belts and shoulder harnesses, safer door latches, non-shattering windshields, and energy absorbing steering columns. Improvements are made constantly in the parts of a vehicle which are obvious to the driver. These parts include windshield wipers, headlamps, brakes, steering suspension, and the exhaust system. The introduction of front and rear directional signals contributes greatly to motor vehicle safety. Stop lights, backup lights, and four-way emergency flashers also aid in vehicle safety. Four-way emergency flashers have
25
become standard equipment for vehicles.
208. According to the passage, which is NOT mentioned? C A. safety belts B. safer door latches C. brake pedal
209. According to the passage, which becomes standard equipment for vehicles? A A. four-way emergency flashers B. guard rail C. ventilating system
210. Which of the following is true? B
A. Vehicular safety design usually centers on protecting the passengers and the vehicles B. Vehicular safety design usually centers on protecting the passengers and the persons who
drives the vehicles
C. Vehicular safety design usually centers on protecting the passengers and the pedestrians 211. According to the passage, which design is described? A A. vehicular safety B. vehicular structure C. vehicular power
Passage Ten
In the 1930s engineers found that superior embankments could be constructed by spreading the material in relatively thin layers and compacting it at moisture content close to optimum. The improvement resulted largely because greater density was obtained, which resulted in higher “strength” in the soil mass and in decreased settlement and rutting. Layered construction also produced greater uniformity in the material itself and in its density and moisture content. This was beneficial since any subsequent consolidation or swelling would be relatively uniform. 212. In the 1930s engineers found embankments could be constructed by B
