10、iston moves from one limiting position to the other. The upper limit of piston movement is called TDC （top dead center）. The lower limit of piston movement is called BDC （bottom dead center）. A stroke is piston movement from TDC to BDC or from BDC to TDC. In other words, the piston completes a strok

11、e each time it changes its direction of motion. Where the entire cycle of events in the cylinder requires four strokes （or two crankshaft revolutions）, the engines is called a four-stroke-cycle engine, or a four-cycle engine. The four piston strokes are intake, compression, power, and exhaust. 1. Wh

12、at do we see from the paragraphs? （ ） A. What is stroke? B. What is engine? C. What is cylinder?2. Which one Statement is true according the above first paragraph? A. A four-stroke-cycle engine means that four strokes is required when it finish the whole cycle. B. A stroke is not piston movement fro

13、m TDC to BDC, but from BDC to TDC. C. The lower limit of piston movement is called TDC （top dead center）. 3. What is BDC in the term of automobile industry? ） （ A. Bottom dead center. B. Top dead center. C. Neither of A and B. 4. Which one Statement is TRUE according the last paragraph?3 A. The four

14、 strokes occur in two crankshaft revolutions. B. The four strokes occur in four crankshaft revolutions. C. The four strokes occur in one crankshaft revolutions. 5. Which one Statement is TURE according the article?） （ A. The four piston strokes are intake, compression, power, and exhaust. B. The four piston strokes are intake, compression, power, and inhauls. C. The four piston strokes are intake, combining, power, and exhaust. Part 2 Power stroke: As the piston reaches TDC on the compression s
