1、杭 州 师 范 大 学 硕 士 研 究 生 入 学 考 试 命 题 纸杭 州 师 范 大 学 2018 年招收攻读硕士研究生入学考试题 考试科目代码: 243 考试科目名称: 二外英语 说明:考生答题时一律写在答题纸上,否则漏批责任自负。Part I Reading Comprehension (Skimming and Scanning) (210=20 points)Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on the
2、 Answer Sheet.For questions 1 - 7, markY (for YES) if the statement agrees with the information given in the passage;N (for NO) if the statement contradicts the information given in the passage;NG (for NOT GIVEN) if the information is not given in the passage.For questions 8 - 10, complete the sente
3、nces with the information given in the passage.AirplaneAirplane InstrumentsModern airplanes are complicated machines. Pilots need many gauges(量表) and electronic aids to help fly them. The flight deck of a large passenger plane contains many indicator dials and warning lights. One of the most importa
4、nt instruments is the altimeter, which tells the pilot how high the plane is off the ground. The air speed indicator measures the planes speed. The artificial horizon shows the position of the plane relative to the horizon. The turn and back indicator shows how much, if at all, the plane is turning
5、and tilting. In dense clouds and fog, a pilot would not always know which way the plane is heading if it werent for this instrument. A gyrocompass(旋转罗盘)and various radio devices are necessary for navigation.Most large planes also have an automatic pilot. This is a device operated by a computer. It w
6、ill fly the plane without the pilots touching the controls. These autopilots can even control takeoffs and landings. The flight deck also contains many gauges and meters that tell the pilot whether the many pieces of equipment on the plane are operating properly. They measure fuel level, temperature
7、s, cabin pressure, electric current, etc. Indicators show whether the landing gear is up or down. The radio equipment allows the pilot to talk to ground controllers and to receive navigation signals.Airplane ConstructionEarly airplanes were made of wood frames covered by fabric and held in shape by
8、wire. After World War I, airplane designers started to use lightweight metals like aluminum, titanium, and magnesium alloys. A thin skin of metal was riveted(固定住) into place over metal ribs. Strong epoxy(环氧的) glues are now used for some joints, instead of rivets. As planes grew in size, they became
9、heavier. More powerful engines were developed in order to fly the heavier planes.The use of metals brings with it a problem called metal fatigue. Stress and vibration in flight can cause metal parts eventually to break up. Airplanes must be constantly checked for signs of this trouble. Defective par
10、ts must be renewed by aircraft maintenance people.Designers test scale models in wind tunnels before the full sized planes are built. Reactions of the models to high speed air streams give good indications how full sized planes will react in flight. This approach helps save a lot of money. It also h
11、elps to make airplanes safe.AirportAn airport is a place where airplanes arrive and depart. Passengers leave and arrive on the airplanes and cargo is loaded and unloaded. Large, jet powered airplanes require long runways for takeoffs and landings. Big terminal buildings are necessary to handle thous
12、ands of passengers and their baggage. Very large airports usually serve several large cities and cover thousands of acres. Hundreds of planes arrive and depart daily. All this traffic must be carefully controlled to avoid delays and accidents. This is done from a control tower. The tower stands high
13、 above the ground. Air traffic controllers, inside the tower, must be able to guide airplanes through their takeoffs and landings.Large airports are often like small cities. Many have post offices, banks, hotels, restaurants, and many kinds of shops. Airports have their own fire and police departmen
14、ts, fuel storage tanks, and repair work shops. Some companies even have their shipping warehouses located at airports.One of the largest airports in the world is in Grapevine, Texas, midway between the cities of Dallas and Fort Worth. This airport covers 7,200 hectares (18,000 acres). Its five termi
15、nals can handle the arrivals and departures of 90 jumbo jets at the same time. OHare International Airport, in Chicago, is the busiest airport in the world. It handles more than 37 million passengers a year.Small airports that are used only by private airplanes usually cover 20 to 40 hectares (50 to
16、 100 acres). They do not need all the buildings and services of a large airport. The control tower may be just a small room in a building at ground level.RunwaysEarly planes were light. Early runways were sometimes just level grass fields. Paved runways became necessary when airplanes became heavier
17、 and faster. Todays big jet planes weigh hundreds of tons. They move along runways at speeds of 160 kph (100 mph). When they land, the runways take a lot of pounding and must be made of concrete or asphalt(沥青). They must have solid foundations and a surface that prevents skidding.Airplanes take off
18、into the wind in order to get better lift. They also land into the wind to have better control as they slow down. Most airports have runways pointing in different directions. This means that there are always runways on which airplanes can go into the wind as they take off and land.Heavily loaded pas
19、senger jets need long runways to gather enough speed to leave the ground. Runways at some large airports are longer than 3,000 m (10,000 ft).At night, bright lights line the runways so that pilots can find them without trouble. A system of flashing guide lights is set up beyond the runway to help pi
20、lots land safely.Control TowersPeople who work in control towers are called air traffic controllers. They direct the movements of all planes on the ground and in the air by keeping track of them on large radar screens. Air traffic controllers tell a pilot, by radio, when and where to taxi or pilot t
21、he plane down the runway.Electronic equipment is used to guide airplanes. Long range radar is used to keep track of planes far away from the airport. This radar is called Ground Control Approach (GCA). When the airplane gets within a few miles of the runway, the air traffic controller begins to use
22、Precision Approach Radar (PAR). This allows the controller to guide the airplane to within 0.4 km (0.25mi) of the runway. At that point, the pilot completes the landing. Another electronic aid used in bad weather is the Instrument Landing System (ILS). In this system, radio transmitters located near
