At first I couldn't believe it! There were no 1 in rows; no bells rang; no one had to go to 2 . Although we all lived “in”, 3 made us go to bed at a certain time; there was no “lights out”.
The 4 thing was that practically all the students went to class, and very few people stayed up late at night. Only the new people stayed up or 5 class. The new ones always went wild at first, but this never lasted long.
The 6 took some getting used to. Our teachers treated us like 7 ; never did we have to 8 “stand up”, “speak out”. I don't 9 one student who didn't try his best.
The subjects were the same as those in 10 school, but what a difference in the approach (方式)! For example, in botany (植物学) we had no classes in spring or fall, but instead we 11 two gardens, a vegetable garden and a flower garden. Then in winter we each studied a few 12 things about what we had grown. In math the students built three different kinds of storerooms-small ones 13 , but unusual. They did this instead of having lessons in the classroom. They really had a 14 time too, designing everything, drawing the blueprints, 15 the angles (角度) and so on. I didn't take math. I can't stand it! Besides, I could do the things with numbers. That's 16 ! 17 , I think I am a 18 person for having gone to the school. I can read and write as well as anyone else of my age, and I can think better. That's probably a real big 19 between the free school and regular school—the amount of 20 .

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
Michel is a young girl who works for the police 36 a handwriting expert. She has helped 37 many criminals (罪犯) by using her special talents.
When she was fourteen, Michel was already 38 interested in the differences in her friends' 39 that she would spend hours 40 them. After 41 college she went to France for a 42 two-year class in handwriting at the School of Police Science.
Michel says that it is 43 for people to hide their handwriting. She can discover _44 of what she needs to know simply 45 looking at the writing with her own eyes, 46 she also has machines 47 help her make 48 different kinds of paper and ink. This knowledge is often 49 great help to the police.
Michel believes that handwriting is a good 50 of what kind of person the 51 is. "I wouldn't go out with a fellow 52 I didn't like his handwriting." She says. But she 53 she fell in love with her future husband, a young policeman 54 she studied his handwriting. It is later proved to be 55 , however.

Everyone has heard of the San Andreas fault （断层）, which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri?
Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, releasing some strong smell chemicals.
The Mississippi River itself completely changed character, developing sudden rapids and whirlpools (激流和漩涡). Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Marid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C.
Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the two masses make a sudden move.
The New Madrid fault, on the other hand, is a vertical fault; at some points, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions cause earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois.
Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the area since 1811; these smaller quakes indicate that larger ones are probably coming, but the scientists say they have no method of predicting when a large earthquake will occur.
1.This passage is mainly about ___________.
A. current scientific knowledge about faults
B. the San Andreas and the New Madrid faults
C. the causes of faults
D. the New Madrid fault in Missouri
2.The New Madrid fault is __________.
A. a vertical fault
B. a horizontal fault
C. a more serious fault than the San Andreas fault
D. responsible for forming the Mississippi River
3.This passage implies that _________. .
A. horizontal faults are more dangerous than vertical faults
B. Vertical faults are more dangerous than horizontal faults
C. The volcanoes that caused the New Madrid fault are still alive
D. A lot of people would die if the 1811 New Madrid earthquakes happened today
