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 w i both the i l t and exhaust th n e val cl ve osed , the pi ston m oves up the cyli nde r, com pr essi ng the f l m i ue xture . Just before the end of the stroke , an electric spark across the poi ts of the sparki n ng pl ug i ite s the petro l and ai m i gn r xture . 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

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.
