4 NGÂN HÀNG CÂU HỎI
4.1.Câu hỏi loại 1
1 The four- stroke cycle
Induction stroke with the inlet valve open and the exhaust valve shut, the piston
moves down the cylinder create a partial vacuum This partial vacuum draws in the atomized fuel from the carburettor into the cylinder
Compression stroke with both the inlet and exhaust valve closed, the piston moves
up the cylinder, compressing the fuel mixture Just before the end of the stroke, an electric spark across the points of the sparking plug ignites the petrol and air mixture
Power stroke Both valves remain closed During the tiny interval of time required
for flame to establish itself, the piston has reached its highest position in the cylinder The gas generated by the burning fuel now expands rapidly, driving the piston down the cylinder This downward push is converted into a rotary movement by the connecting rod and crankshaft A water jacket contained within the cylinder walls helps to conduct away the heat generated during this burning and thus keeps the engine cool
Exhaust stroke The exhaust valve opens but the inlet valve remains shut The piston
moves up the cylinder, pushing the exhaust gas out through the exhaust valve With the completion of the exhaust stroke the cycle begins again
a Answer the questions:
1 Say which word in the text has the same meaning as “a flash of light”
2 Find in the text which word means “produced”
3 In the text which word has the same meaning as “closed”
4 In power stroke what causes the piston to move down the cylinder?
5 There are three differences between Induction and Exhaust stroke What are they?
b.Are these sentences True or False ? Write T (True) or F ( False) at the end of the sentence.
1 During the process of induction stroke, the inlet valve and exhaust valve open at the same time
2 The fuel mixture is compressed by the piston
3 The piston moves down the cylinder when the gas expands quickly
4 Some water is placed outside the cylinder to conduct away the heat and keep the engine cool
5 After the exhaust gas has been totally released, a new cycle begins
2 Consumption of energy resources, (e.g turning on a light) is apparently harmless However, producing that energy requires resources and contributes to air and water pollution Many electric power plants burn coal oil or natural gas in order to generate electricity for energy needs While burning these fossil fuels produces a readily available and instantaneous supply of electricity, it also generates air pollutants including carbon dioxide (CO2), sulfur dioxide and trioxide (SOx) and nitrogen oxides (NOx) Carbon dioxide is an important greenhouse gas which is thought to be responsible for some fraction
of the rapid increase in global warming
Burning fossil fuels for electricity generation also releases trace metals such as beryllium, cadmium, chromium, copper, manganese, mercury, nickel, and silver into the environment, which also act as pollutants Certain renewable energy technologies do not pollute the environment in the same ways, and therefore can help contribute to a cleaner energy future for the world Renewable energy technologies available for electricity production include biofuels, solar power, tidal power, wind turbines, hydroelectric power, etc However, serious environmental concerns have been articulated by several environmental activists regarding these modes of electricity generation According to them, some pollution is
Trang 4invariably produced during the manufacture and retirement of the materials associated with the machinery used in these technologies A central way to avoid downsides of expanding energy production is energy conservation
a Answer the questions:
1.Does consumption of energy make the air and water polluted?
2.To generate electricity what are burned by many electric power plants?
3 What air pollutant generated while burning fossil fuels has a great contribution to global warming?
4.What trace metals that pollute the environment are released while burning fossil fuels?
5.What do renewable energy technologies consist of?
b Are these sentences True or False ? Write T (True) or F ( False) at the end of the sentence.
1 The production of energy is polluting air and water
2 Sulfure dioxide is the air pollutant which partly contributes to global warming
3 Some kinds of trace metals appear in the process of burning fossil fuels for
electricity generation
4 According to several environment activists,renewable energy technologies do not pollute the environment any more
5 Energy conservation helps to avoid the problem of energy production
3 Jet engines
The three most common types of jet engines are the turbojet, turboprop, and turbofan Air entering a turbojet engine is compressed and passed into a combustion chamber to be oxidized Energy produced by the burning fuel spins the turbine that drives the compressor, creating an effective power cycle Turboprop engines are driven almost entirely by a propeller mounted in the front of the engine, deriving only 10% of their thrust from the exhaust jet Turbofans combine the hot air jet with bypassed air from a fan, also driven by the turbine The use of bypass air creates a quieter engine with greater boost at low speeds, making it a popular choice for commercial airplanes
The turbine or jet engine operates on the principle of Newton’s it all about?s third law of motion, which states that for every action, there is an opposite but equal reaction A jet sucks air into the front, squeezes the air by pulling it through a series of spinning compressors, mixes
it with fuel and ignites the mixture, which then explodes with great force rearward through the exhaust nozzle The rearward force is balanced with an equal force that pushes forward the jet engine and the airplane attached to it A rocket engine operates in the same principle except that, in order to operate in the airless vacuum of space, the rocket must carry along with its own air, in the front of solid propellant or liquid oxidizer for combustion
a Answer the questions:
1 What does “it” (paragragh 1) refer to ?
2 What happens to the air after it enters the turbojet engine?
3 What does “which” (paragragh 2, line 1) refer to ?
4 What word in paragragh 1 has the same meaning as “completely”?
5 How is a rocket engine different from a jet engine?
b Are these sentences True or False ? Write T (True) or F ( False) at the end of the sentence.
1 The air entering a turborjet engine is compressed in the combustion chamber
2 A propeller mounted in the front of the engine drives turboprop
3 The use of bypass air helps to provide more choices for commercial air planes
4 The Newton’s it all about?s second law of motion is about an equal reaction in every action
5 The principle for a rocket engine to operate is totally the same as that for a jet engine
4 Today engines can produce enough power to lift the heaviest weights and drive the largest machines The most powerful engine is the rocket engine, it can blast a spacecraft away from the pull of the Earth's gravity and out into space
The engine that powers almost the world's cars is the internal-combustion engine It uses the power of gases created by exploding fuel to produce movement A mixture of air and tiny droplets of gasoline enters the engine's cylinders, each of which contains a piston
An electrical spark ignites the fuel mixture, producing gases which thrust each piston down
Trang 5Many trains and trucks have been powered by diesel engine, which are internal-combustion engines that burn diesel fuel instead of gasoline The engine works in the same way as a gasoline-fueled engine, but does not have spark plugs Instead, each cylinder has
an injector that squirts diesel fuel into the cylinder The piston compresses the air, making
it very hot The hot air makes the diesel fuel explode
If we use only gasoline and diesel engines today, there would be many problems with the environment These kinds of engines produce waste gases that pollute the air and contribute to the greenhouse effect which causes the Earth's temperature to rise Fortunately, electric motors, which are clean, quiet, and produce no pollution, have been used as an alternative In fact, several car manufacturers are developing cars powered by electric motors However, most electric cars are still experimental If efficient batteries are successfully developed, electric cars will be an ideal solution for transportation
a Answer the questions:
1 Which engine is the most powerful?
2 What kind of engine powers almost all the world's cars?
3 Do diesel engines have spark plugs?
4 How does the diesel engine operate?
5 What happens if we use diesel engines today ?
b Are these sentences True or False ? Write T (True) or F ( False) at the end of the sentence.
1 There are three kinds of engine mentioned in the passage: rocket engine, gasoline engine, and diesel engine
2 Cars can move due to the power of gases created by exploding fuel
3 Only trains have been powered by diesel engine
4 The piston compresses the air and makes the diesel fuel explode
5 Electric cars do not pollute the environment as they are clean and quiet
1 The mechanical valve is one of the oldest pieces of technology known to mankind If
we define a valve as a device to regulate a flow, then the earliest recorded use of a valve was by Egyptian farmers in pre-Pyramid days to control the flow of Nile flood water in specially dug irrigation channels The earliest valve was a simple piece of wood slotted down into a stream Despite the engineering skills of the Romans, a similar device was still being used two thousand years later by Lancashire to cut off the mill stream or raceway, when repairs to the wheel were called for
2 Whatever was happening on the open stream, it was within pipes that valves were developing The Romans had piped water coming in from nearby stream to water towers above the city Basic on/off valves regulated the flow into smaller distribution ducts and thence into private homes Roman valves were cast in bronze and sealed with wood and animal hair against leaks, and some examples in museums show remarkable similarities to modern domestic taps!
3 The development of modern multi-position valves began in this country with the industrial revolution The arrival of steam power and bulk material handling required more than simple on/off regulation of flow With the development of rubber and rubber based materials, valves became more efficient, although 100% shut-off under pressure was still fairly uncommon
a Answer the questions
1 What was the purpose of the earliest valve?
2 What do you know about the earliest valve?
3 Were Lancashire millers still using a valve of Roman design 2000 years after its invention?
4 What were Roman valves made of in order to avoid leaks?
5 When did the development of modern multi-position valves begin?
b Are these sentences True or False ? Write T (True) or F ( False) at the end of the sentence.
1 The earliest valve was invented by the Egyptian farmer in Pre-pyramid days
2 The Lancashire used a new type of valve to cut off the mill stream or raceway
3 In the Romans’s it all about? city, the flow of water was controlled by basic on/off valves
Trang 64 At that time some valves were not remarkably similar to modern domestic taps.
5 The development of rubber and rubber based materials made valves become more efficient
