The day after news broke of a possible revolution in physics ——particles （粒子） moving faster than light ?a scientist leading the European experiment that made the discovery calmly explained it to a standing-room- only crowd at CERN．
The physicist, Dario Auterio, did not try to explain what the results might mean for the laws of physics, let alone the broader world．After an hour of technical talk, he simply said, "Therefore, we present to you today this difference, this unusualness．"
But what unusualness it may be．From 2009 through 2011, the massive OPERA detector （探测器）buried in a mountain in Gran Sasso, Italy, recorded subatomic particles called neutrinos （ 中微子） arriving faster than light can move in an empty space．The neutrinos generated at CERN are hardly detectably early．If confirmed, the finding would throw more than a century of physics into disorder．
"If it's correct, it's phenomenal．" said Rob Plunkett, a scientist at Fermilab, the Department of Energy physics laboratory in Illinois．"We'd be looking at a whole new set of rules" for how the universe works．Those rules would bend, or possibly break, Albert Einstein's special theory of relativity, published in 1905．Basical at the time, the theory tied together space and time, matter and energy, and set a hard limit for the speed of light, later measured to be about 186, 000 miles per second．
No experiment in 106 years had broken that speed limit．Physicists expect strict study to follow, which OPERA and CERN scientists welcomed．
Fermilab operates a similar experiment, called MINOS, that shoots neutrinos from Illinois to an underground detector in Minnesota．In 2007, MINOS discovered a just detectable amount of faster than-light neutrinos, but the permissible difference of error was too big to "mention" , Plunkett said．
Fermilab scientists will reanalyze their data, which will take six to eight months．In 2013, the MINOS detector, now offline, will restart after an upgrade．It could then offer confirmation of the results．
72．Why are the European scientists not sure about the results of the experiment?
A．Because they are so unexpected．
B．Because the scientists do not believe them．
C．Because the scientists are careful and calm．
D．Because they are against the present law of physics．
73．The underlined word " phenomenal" in the fourth paragraph has the closest meaning to .
A．amazing B．attractive C．embarrassing D．sensitive
74．The best title for the passage may be _____．
A．Are the laws of physics in disorder?
B．Particles faster than light; Revolution or mistake?
C．Faster than light measurement: right or wrong?
D．Is Einstein's theory still right today?
75．What may be discussed in the paragraphs to follow?
A．Different opinions about the experiment．
B．How Albert Einstein's theory developed．
C．The new rules for how the universe works．
D．How Fermilab scientists will reanalyze their data．

The cowboys who lived in the United States of America，before there were good roads or big modern cities，used to live on the huge spaces of grassland called ranges，because that was where the cows that they looked after could find plenty of grass and water． 1
In the early days it was a hard job getting the cows to the markets where they were killed．It was no good killing them on the range because there were no lorries or railways to carry the meat． 2
On the trail the leader was the trail boss，who told the men which jobs to do．He decided where they should camp at night．
Hundreds or maybe thousands of cattle were taken on the trail． 3
Of course，the chuck wagon went too．“ Chuck was a cowboy name for food，and so the chuck wagon was where the cook did his work and carried his stores of food．The tail board of the wagon made a good shelf，as the back part of the wagon could open outwards so it served very well as a shelf．The cook was able to feed the cowboys，but the cattle had to find their own food on the trail．They ate as they moved along．
4 The cowboys worked very hard and had little time to play When they were resting on the trail they would play cards，tell stories，sing cowboy songs and mend their equipment．
5 The cattle will also arrive fresh and fat when they arrive at the place whereas they would have become tired and thin if they had been taken on the trail．
A．The cattle had to be driven along in a large herd to the towns where they were needed．The places with lots of people who needed meat were often hundreds or thousands of miles away from the ranges．The cattle were rounded up，and those to be sent away were kept together．
B．It was a long，slow job，and the herd covered only about fifteen or twenty miles each day．This meant that the journey to market took many weeks．All this time the cowboy worked in the saddle and slept on the hard ground．They began work the sun rose and they were on their horses for many hours day after day．
C．Because of the danger of the stampede（惊跑），the trail boss and his men did everything they could to keep the cattle quiet．During the day the herd was moved along at a slow，steady pace．At night when most of the men were asleep，a gang of cowboys would ride round and round the herd，singing and whistling softly．This was to let the cows know that everything was all right．
D．But when the time came to sell the cows，there were no buyers on the range-they had to be taken into market．
E．The herd was not made to move too quickly-if they rushed along they would get thin and not be worth much at the market．Some cowboys rode beside them，some in front and others at the back．Cows which moved too slowly were hurried along．Cows which tried to get away were made to go back to the herd．
F．When railways were built there were no need to take cattle on the trail．Instead they were put into railway cars and taken quickly to the markets．Today a fast cattle train will take only a few hours to do a journey which once took the cowboys and their herds many days or weeks．

Bill Javis took over our village’s news-agency at a time of life when most of us only wanted to relax. He just thought he would like something but not too much to do, and the news-a??gency was ready-made. The business produced little enough for him, but Bill was a man who only wanted the simplicity and order and regularity of the job. He had been a long-serving sailor, and all his life had done everything by the clock.
Every day he opened his shop at 6:00 a. m. to catch the early trade; the papers arrived on his doorstep before that. Many of Bill’s customers were city workers, and the shop was convenient for the station. Business was tailing off by 10 o’clock, so at eleven sharp Bill closed for lunch. It was hard luck on anybody who wanted a paper or magazine in the after??noon, for most likely Bill would be down on the river bank, fishing, and his neatest competitor was five kilometers away. Sometimes in the afternoon-, the evening paper landed on the doorway, and at 4 o’ clock Bill reopened his shop. The evening rush lasted till seven, and it was worthwhile.
He lived in a flat above the ship, alone. Except in the very bad weather, you always knew where to find him in the af??ternoon, as I have said. Once, on a sunny afternoon, I walked home along the river bank from a shopping trip to the village. By my watch it was three minutes past four, so I was aston??ished to see Bill sitting there on his little chair with a line in the, water. He had no luck, I could, see, but he was making no effort to move. “What’s wrong, Bill?” I called out from the path.
For answer, he put a hand in his jacket and took out a big, golden object. For a moment I had no idea what it could be, and then it suddenly went off with a noise like a fire en??gine. Stopping the bell, Bill held the thing up and called back, "Ten to four, you see, and this is dead right. "
I had never known anyone carrying a brass alarm clock round with him before.
5. Bill Javis became a news-agent when ________.
A. he need the money. B. he decided to take things easy
C. he was quite an old man D. he gave up clock-repairing
6. Bill opened the shop so early in the day because ________.
A. he liked to do as much as possible before he went to work
B. the shop had to be open when the morning papers came
C. he was never sure of time
D. it was then that he did a lot of business
7. On that sunny afternoon, the writer was surprised when he saw Bill because ________.
A. he thought it was late for Bill to be still fishing
B. he thought Bill was ill, since he was not moving at all
C. Bill had not caught anything, and that seemed strange
D. Bill stayed in his flat
8. From the information given in the passage, who or what do you think was wrong?
A. The bell was; it must have gone off at the wrong time.
B. Bill was; he had dropped off to sleep.
C. The writer’s watch was fast.
