三、阅读与理解（10题，每题3分，共30分）
Part 1
The engine is the source of power that makes the wheels go around and the car move. The automobile engine is an internal combustion engine because the fuel (gasoline) is burned inside it.
The burning of gasoline inside the engine produces high pressure in the engine combustion chamber .This high pressure forces piston to move, the movement is carried by connecting rods to the engine crankshaft. The crankshaft is thus made to rotate: the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves.
1. What do we see from the FIRST paragraph? ( A )
A. The engine is source of power for a car.
B. The engine can not make wheels go around.
C. The engine is resource of oil.
2. Which Statement is TRUE according to first paragraph? ( A )
A. The automobile engine is an international combustion engine.
B. The automobile engine is an external combustion engine.
C. The automobile engine is an inner combustion engine
3. What do we see from the second paragraph? ( A )
A. High pressure is source of power inside a engine.
B. Crankshaft is rotated without any force.
C. Combustion chamber is not a part of the engine.
4. Which one statement is TRUE according to the second paragraph? ( A )
A. The movement of piston is carried by connecting rods to the engine crankshaft.
B. .This lower pressure forces piston to move.
C. Both of A and B are true.
5. Which statement is TRUE according the last sentence in the article? ( C )
A. The power train is required for a car moving.
B. The rotary motion of crankshaft is enough for a car moving.
C. Both A and B are false.
Part 2
The engine also needs a cooling system; the combustion of the air-fuel .The mixture in the engine creates a very high temperature (as high as 2000℃ to 2700℃). The cooling system takes heat away from the engine by circulating a liquid coolant (water mix with antifreeze) between the engine and a radiator .The coolant gets hot as it goes through the radiator. Thus, the coolant continually takes heat away from the engine, where it could do damage, and delivers it to the radiator .Air passing through the radiator takes heat away from the radiator.
6. What do we see from above paragraph? ( A )
A. a cooling system is must for the engine .
B. The engine don’t need a cooling system
C. The engine might need a cooling system.
7. How much will be created the temperature of the mixture in the engine? ( A )
A. As high as 2000℃ to 2700℃.
B. As high as 1300℃ to 2000℃.
C. Not higher than 2000℃.
8. What is liquid coolant? ( A )
A. water mix with antifreeze
B. water used by the cooling system.
C. Any liquid used by the cooling system.
9. What do we see from above paragraph? ( B )
A. The coolant gets HOT as it goes through the radiator
B. The coolant gets COOL as it goes through the radiator
C. Both A and B are false.
10. Which Statement is TRUE in the article? ( A )
A. Air passing through the radiator takes heat away from the radiator.
B. Air passing through the radiator gets more heat.
