  Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in this world?A small group of emgineers and robotics experts picture a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.

  One of the first mining robots was developed five years ago at Carnegie-Mdllon University’s Robotics Institute.It was called Groundhog and it looked like a golf cart,.It used lasers(激光)to“see”in the dark and map given up mines-some of the most dangerous work in the business.

  The latest model is called Cave Crawler, It’s a bit smaller than grouondhog.and even more Advanced.It can take photos and videos and has sensors that can discover the presence of dangerrous gasses.Amazingly.the robot has a real sense of logic(逻辑性).If it comes acorss something difficult, it gets monentarily punded.It has to think about what to do and where to go next.Sometimes it throws a fit just like a real person.

  Myles and his colleagues hope that robots like Cove Crawler will one day be used in rescue(营救)operations“A robot could speed up the rescue process by doing discovery(侦察),”says Chuck Whittaker, a roboties engineer at Carnegie-Mellon.“The robot can go ahead and, with its sensors, report what it has found and whether jit is safe for humans to proceed.”

  Using robots in rescue operations, though, is probliematic, The lasers that guide the robots don’t work in smoky environments so the engineers at Carnegie Mellon have experimnted with sonar(声纳)and radar guidance systems, and with some success.

  Some experts predict that robots do the most repetitive and dangerous jobs, but won't get rid fo the need for human workers.

(1)

The underlined phrase“throws a fit”in Paragraph 3 probably means ________

[  ]

A.

gets angry

(2)

The latest robot is more advanced than Groundhog mainly because ________

[  ]

A.

C.

it’s smaller than Groundhog

D.

it has a real sense of logic

(3)

(4)

We can infer from the last paragraph that ________

[  ]

A.

the mine robots will have a very bright future

B.

robots in the sutomotive industry must be improved

C.

  Visitors to Switzerland usually include Basel in their list of cities to visit. It has a population of over350 000, the majority of whom speak German. However, it is considered a kind of international city, because it stands at the point where three countries meet. Many visitors go to the place in the city where a small three side marker stays?   France on one side, Germany on another, and Switzerland on the third. The Rhine, which divides the city, becomes wide and deep enough just at this point for ships to sail all the way up to the North Sea. Basel is quite an old city, too, having risen five centuries ago. The University Basel was founded in 1860, and it is well-known today.

  The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said good-bye to each other forever. He sent his camera crew(摄制组)out one evening to film the sunset for him.

  The next morning he said to the men,“Have you provided me with that sunset?”

  “No, sir,”the men answered.

  The director was angry.“Why not?”he asked.

  “Well, sir.”one of the men answered, “we're on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”

  “But I want a sunset!”the director shouted.“Go to the airport, take the next flight to the west coast, and get one.”

  But then a young secretary had an idea.“Why don't you photograph a sunrise,”she suggested,“and then play it backwards. It'll look like a sunset.”

  “That's a very good idea!”the director said. Then he turned to the camera crew and said,“Tomorrow morning I want you to get me a beautiful sunrise over the sea.”

  The camera crew went out early the next morning end filmed a bright sunrise over the beach in the middle of a beautiful bay (海湾). Then at nine o'clock they took it to the director.“Here it is, sir.”they said, and gave it to him. He was very pleased.

  They all went into the studio (摄影棚).“All right.”the director explained.“Now our hero and heroine are going to say good-bye. Run the film backwards so that we can see the‘sunset’behind them.”

  The“sunset”began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.

  The birds in the film were flying backwards, and the waves on the sea were going away from the beach.

1.Which of the following statements is NOT true?

[  ]

A.The crew had to follow the secretary's advice.

B.If you want to see a sunrise, the east coast is the place to go to.

  A few days ago I asked my son's governess(女家庭教师)Julia to come into my study.“Be seated, Julia,”I said, “Let's settle our accounts.I guess you most likely need some money, but maybe you're too polite to mention it.Now then, we agreed on thirty dollars a month…”

  “Forty.”

  “No, thirty.I made a note of it.I always pay our governess thirty.Well, um, you've been here two months, so…”

  “Two months and five days.”

  “Exactly two months.I made a special note of it.That means you have sixty dollars coming to you.Take off nine Sundays…you know you didn't work with Tom on Sundays, you only took walks.And three holidays…”Julia was biting her finger nail nervously, her face red, but-not a word.

  “Three holidays, therefore take off twelve dollars.Four days Tom was sick and there were no lessons, as you were occupied(从事)only with Dick.Three days you had a toothache and my wife gave you permission not to work after lunch.Twelve and seven-nineteen.Take nineteen off…that leaves…hmm…forty one dollars.Correct?”

  Julia's left eye reddened with tears welling up.Her chin trembled; she coughed nervously and blew her nose, but-still not a word.

  “Around New Year's Day you broke a teacup and a saucer; take off two dollars.The cup cost more, it was a treasure of the family, but - forget it.When didn't I take a loss! Then, due to your neglect(疏忽), Tom climbed a tree and tore his jacket; take away ten.Also due to your carelessness the maid stole Dick's shoes.You ought to watch everything! You get paid for it.So, that means five more dollars off.The tenth of January I gave ten dollars.”

  “You didn't.” sobbed Julia.

  “But I made a note of it.”

  “Well…if you say so.”

  “Take twenty seven from forty one-that leaves fourteen.”

  Both her eyes were filled with tears.Beads of sweat stood on the thin pretty little nose.Poor girl!

  “Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife.Three dollars, nothing more.”

  “Really? You see now, and I didn't know that! Take three from fourteen-that leaves eleven.Here's your money, my dear.Three, three, three, one and one.Here it is!”

  I handed her eleven dollars.She took them and pocketed them.

  “Merci(法语:谢谢),”she whispered.

  I jumped to my feet and started pacing the room.I was overcome with anger.“For what, this ‘merci'?” I asked.

  “For the money.”

  “But you know I've cheated you-robbed you! I have actually stolen from you! Why this ‘merci'?”

  “In my other places they didn't give me anything at all.”

  “They didn't give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you...I m going to give you all the eighty dollars! Here they are in the envelope all ready for you...Is it really possible to be so spineless(懦弱)?Why didn't you protest? Why were you silent? Is it possible in this world to be without teeth and claws(爪)-to be such a fool?”

  Embarrassed, she smiled.And I could read her expression, “It is possible.”

  I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars.She murmured her little “merci” several times and went out.I looked after her and thought, “How easy it is to crush(压榨)the weak in this world !”

     CBC is a famous air company which has over twenty planes carrying passengers and goods, flying
along 12 fixed lines all over the world. Its service is very good but some passengers are still not satisfied

table. This division is called Category. Problems that appear when the plane is flying are Flight problems.
Those about passengers' things carried by the plane are Baggage problems. Customer service refers to
service work which passengers are not satisfied with. Over sales of seats are about the fact that more seats
are sold and as a result the plane is too crowded to be safe. Refund problems appear when passengers fail
to receive the money paid to them because of what they have lost. Fares are problems about the price of
tickets. Reservations are problems that appear when passengers could not get the tickets they have already
booked. Tours are problems about the passengers'traveling by air or hotel problems. Advertising is what the
passengers think about advertisement on the plane. Credit problems are about the use of credit cards.
