Fear is the driver's constant companion, and tragedy can be just a step behind.Scarcely a man in the 500 does not carry the scars of ancient crashes.The mark of the plastic surgeon is everywhere, and burned skin is common.Sometimes a driver's scars are invisible, part of his heritage.Two young drivers, Billy Vukovich and Gary Bettenhausen, raced in their first 500 in 1968.Less than 20 years before, their fathers also competed against one another on the Indy track-and died there.All this the drivers accept.Over the years, they have learned to trust their own techniques, reflexes, and courage.They depend, too, on a trusted servant-scientific engineering.Though they may not have had a great deal of schooling(an exception is New Zealand's Bruce McLaren, who has an engineering degree), many drivers are gifted mechanics, with a feeling for their engines that amount to kinship.A few top drivers have become extremely wealthy, with six-figure incomes from prize money, endorsements, and jobs with auto-product manufacturers.Some have businesses of their own.McLaren designs racing chassis(底盘).Dan Gurney's California factory manufactured the chassis of three of the first four ears in the 1968 Indy 500, including his own second place car.Yet money is not the only reason why men race cars.Perhaps it isn't even the major reason.Three-time Indy winner(1961,1964,1967)A.J.Foyt, for example, can frequently be found competing on dirty tracks in minor-league races, where money, crowds and safety features are limited, and only the danger is not.Why does he do it？ Sometimes Foyt answers, "It's in my blood." Other times he says, "It's good practice." Now and then he replies, "Don't ask dumb questions." 1.The statement "it is usually their nerves that go first" means ________. A.at first they all have a nervous look B.they often find they can't bear the tension even if they are in good condition C.someday they find they can't make responses to any risk D.they can continue their career at most until the middle 40s 2.It can be inferred that a car accident is often coupled with ________.

A.he himself designs chassis B.he has an engineering degree C.he manufactures chassis D.he is a gifted mechanic 5.A.J.Foyt often takes part in minor-league races for ________.
