【单选题】
A car is made up of more than 30,000parts. Each part in a new car is as weak as a baby. So a new car requires proper care and servicing. If you’re unfamiliar with the parts, you have to read through the owner’s instructions carefully. First of all, the brakes (刹车) of your car are important for safety (安全) reasons. Having them checked regularly can reduce the risks of accidents. Another important thing to consider is engine care. Always remember that the life and performance of your car engine depend on the engine oil. Replace the engine oil when recommended. If you feel the engine is very hot especially during summer it is probably because the cooling system doesn’t work well. You’d better get the cooling system serviced before the start of summer. In a word, timely and proper servicing is an important task for car owners. Good servicing can not only extent the life of your newborn baby, but also ensure your safety, and the safety of those who share the road with you.
A.
The last paragraph tells us that the purpose of carefully servicing a car is ______. to let you sell your car at a good price
B.
to extend its life and ensure safety
C.
to reduce the cost of car servicing
D.
to make the car run faster
