Do you suppose Darwin, one of the greatest scientists of all time, really did fools experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution (解決辦法) to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for (滿足于) just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight (緊的) little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientist sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.

You never see him, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潛水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the back of the plane – the area least subject to impact – from its original position in the landing wells (起落架艙). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔絕的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can resist massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
What does the author say about the black box?
A. It ensures the normal functioning of an airplane.
B. The idea for its design comes from a comic book.
C. Its ability to resist disasters is incredible.
D. It is an indispensable device on an airplane.
What information could be found from the black box on the Yemeni airliner?
A. Data for analyzing the cause of the crash.
B. The total number of passengers on board.
C. The scene of the crash and extent of the damage.
D. Homing signals sent by the pilot before the crash.
Why was the black box redesigned in 1965?
A. New materials became available by that time.
B. Too much space was needed for its installation.
C. The early models often got damaged in the crash.
D. The early models didn't provide the needed data.
Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?
A. To distinguish them from the colour of the plane.
B. To caution people to handle them with care.
C. To make them easily identifiable.
D. To conform to international standards.
What do we know about the black boxes from Air France Flight 447?
A. There is still a good chance of their being recovered.
B. There is an urgent need for them to be reconstructed.
C. They have stopped sending homing signals.
D. They were destroyed somewhere near Brazil.
You don’t expect your child to grow up to be a heroin addict．From the moment of her birth, you have hopes and dreams about the future，but they never include heroin addiction．That couldn’t happen to your child, because addiction is the result of a bad environment．bad parenting．There is most definitely someone or something to blame．
That’s what I used to believe．But after failed rehab and long periods of separation from my heroin-addicted daughter，after years of holding my breath，waiting for another relapse，I now believe there is no blame．
After Katie admitted her addiction．I struggled to understand how this could have happened to my daughter—a bright，beautiful，talented and most importantly，loved young woman．When the initial shock wore off,I analyzed and inventoried all the whys and hows of Katie’s addiction．I searched for someone or something to blame．I blamed her friends．I blamed her dad．I blamed our divorce．But mostly, I blamed myself．My desperate heart convinced me that I should have prevented Katie’s addiction．a(chǎn)nd that given another chance．I could correct my mistakes．
When Katie came home from rehab．I approached each day with the zeal of a drill sergeant. I championed the 12-step program and monitored her improvement daily as though curing heroin addiction was as simple as nursing a cold．I drove her to therapy sessions and AA meetings． I controlled everything and left nothing to chance. But in spite of my efforts，Katie didn’t get better．She left my home，lost again to the powerful grip of addiction．
In the long days，weeks and months that followed，I gathered bits and pieces of old beliefs and tried to assemble them into something whole．Sometimes I gave up．a(chǎn)nd sometimes I simply let go,Gradually, my search for blame changed to a longing for hope．I comforted myself with the only thing that still connected me to my daughter：love．
I thought about Katie every day，and I missed her．I cried．a(chǎn)nd worried about her safety and whereabouts. I wrote letters I knew she’d never see．Sometimes I woke up panicked in the middle of the night, certain that mother’s intuition(直覺)was preparing me for something bad．But through it all，I loved her.
I don’t know why or how my daughter became addicted to heroin：I do know that it doesn’t really matter．Life goes on and Katie is still my daughter．
Katie and I meet for breakfast on Friday mornings now．We drink coffee and talk．I don’t try to heal her. I just love her．Sometimes there is pain and sorrow，but there is no blame．I believe there is only love．

You heard about the sign posted on a farm fence? Inside there was a big and mean (兇的) bull. The sign read, “Don’t attempt to cross this field unless you can do it in 9.9 seconds. The bull can do it in 10!”
Don’t try to cross that field unless you are prepared! And isn’t that the way it is in life? We have to be ready when the opportunity arises or else we will have little chance of success.
Sixth-grade teacher Ms. Shelton believed in readiness. When she walked into the classroom on the first day and began writing words of an eighth-grade level on the blackboard, the students immediately said that the words were not at their level and they couldn’t learn them.
Their teacher insisted that they could and would learn these words. She said that she would never teach down to them. Ms. Shelton ended by saying that one of the students in the classroom could go on to greatness, maybe even be president someday, and she wanted them to prepare for that day.
Ms. Shelton said those words many years ago. Little did she know that someday one of her students—Jesse Jackson—would take them seriously. She believed that if they were well prepared, they could achieve high goals.
Ralph Waldo Emerson once said, “People only see what they are prepared to see.” If that’s true, then it is also true that they only become what they are prepared to become. And a lot of life is just about getting ready.
Think of today as a chance to prepare yourself for the exciting future you are looking for. Today is not wasted. If you desire more from life, you can use today as training. For you will experience only what you are prepared to experience. Something wonderful can happen. And you can use today to get ready for tomorrow.
68. What is the function of the first paragraph to the whole passage?
A. To explain the high speed is important to our lives.
B. To show we should get ready when the opportunity arises.
C. To introduce how to grasp the best way to cross this field.
D. To prove it’s right for Ms. Shelton to believe in readiness.
69. Why did Ms. Shelton insist students could and would learn the words of an eighth-grade level?
A. Because she believed one of the students in the classroom could go on to greatness.
B. Because the words of an eighth-grade level is just so so to the Sixth-grade students.
C. Because she believed that if they were well prepared, they could achieve high goals.
D. Because it is also true that they only become what they are prepared to become.
70. What can be the best title of the passage?
A. Get Ready for Tomorrow B. Don’t Waste Time
C. Challenge Yourself D. Ms. Shelton, a Famous Teacher
You get all sorts of demands, and the mark of a good hotel is to supply whatever is asked for without sounding surprise. If a guest asks for rubber gloves. You don't ask why. You say, “No problem. What colour do you want？”
There have been some demands which, much as I would have liked to fill, I couldn't. A Japanese businessman， for example， thought the manager of a hotel was like the captain of a ship so he asked me to marry him and the woman he loved. There was one time, however, we did help out. A young man thought that if he asked his girlfriend to marry him at the Ritz she would say yes. He asked us to put the ring in a cake, and she accepted.
Top hotels are used more and more to impress. They are used for doing business. If you've got something to sell, take your clients(客戶) to the best hotel where the surroundings are quite helpful. A friend of mine working at Savoy Hotel tells story about a man who gave him 5 pounds to say “Good morning, Mr. Smith” when he walked through the door with two other men. This he did， and could hear Mr. Smith saying, “I do wish they would leave me alone at this place.”
According to Julian Payne， the most powerful people in any hotel are the porters， who carry bags for hotel guests. “Porters can do almost anything. They can get you tables at the best restaurants or tickets for a popular concert. Don't ask me how they do it or what their deal is because I don't know. Most of them have been there for years. They know more about the history of the hotel and the guests than anyone else. They are invaluable. A head porter will come in even on his day off so he can say hello to someone he remembers visiting the hotel years ago.”
56．When guests ask for something strange，the manager of a good hotel would think ______.
A．how he can meet their needs
B．why they have such demands
C．what problems the hotel has
D．who is the best person to go to
57．Which of the following examples explains “we did help out？”
A．The hotel bought a ring for a young lady.
B．A Japanese married the woman he loved.
C．The manager once acted as a captain.
D．A young lady agreed to marry her boyfriend.
58．Which of the following statements is true about the porters in expensive hotels?
A．They sell tickets for concerts.
B．They know how to make a good deal.
C．They know a lot about the hotels and the guests.
D．The come to work even on their days off.
59．By saying “I do wish they would leave me alone at this place”， Mr. Smith ______.
