　　Elijah McCoy（1843～1929）, a mechanical engineer, worked with locomotives and parts of locomotives. He invented a self-lubricating（自动加油）machine. The machine makes it possible for machines to lubricate themselves—to put oil on themselves, that is.

　　McCoy, a black man who was the son of slaves, called his first lubricating machine a“lubricator cup”. The cup allowed small drops of oil to drip continuously onto the moving parts, keeping the machine in good running order.

　　As slaves, McCoy’s parents lived in Kentucky. They fled from the United States and settled in Canada. Elijah was born in Colchester, Ontario, Canada, in 184(3) McCoy’s father worked hard in Canada. With pride, he sent Elijah to Edinburgh, Scotland. The boy was then fifteen years old. Elijah McCoy attended a school of engineering in Edinburgh. He studied mechanical engineering. Upon completing his studies, McCoy returned to the United States. No one wanted to hire a black man as a mechanical engineer. Finally McCoy took a job as a fireman for the Michigan Central Railroad.

　　McCoy shoveled（铲）coal and oiled the moving parts of the locomotive. This was a hard job for a mechanical engineer! But McCoy gave some thoughts to his work. Suddenly he had an idea. Why couldn’t a train oil itself? McCoy then invented the self-lubricating machine.

　　Perhaps you have heard the expression“the real McCoy”. The expression is applied（应用）to high quality tools and machines. Railroad men who used the self-lubricating machine boasted（自夸）of having“the real McCoy”.

(1) McCoy’s first invention was ________.

[　　]

A．a machine used to make other machines lubricate themselves

B．some cups which could put oil on themselves

C．a kind of cup used to drop oil to itself

D．a machine which dripped continuously and always kept in good running order

(2) McCoy ________ and returned to the US after completing his study of engineering.

[　　]

A．left the US with his parents when he was 15

B．left Canada for Scotland in 1858

C．fled from the US and came to Canada in 1843

D．with his parents came to Scotland when he was a slave in the US

(3) McCoy was a famous American ________ who invented a self-lubricating machine

[　　]

A．son of slaves

B．fireman

C．mechanical engineer

D．real McCoy

(4) It was unfair that ________.

[　　]

A．a black man took a job as a fireman

B．a train couldn’t oil itself

C．“the real McCoy”was applied to tools and machines

D．an engineer should be offered a job of shoveling coal and oiling machines

(5) McCoy not only invented a lubrication machine, he also ________.

[　　]

A．was“the real McCoy”

B．added a phrase to the English language

C．invented many other lubricating machines

D．could make trains keep in good running order
