A microscope is a useful instrument for observing small objects. By producing a bigger image, the microscope reveals details that are undetectable to the naked eye(裸眼).
Before using the microscope, please read the instructions below.
CAUTION: Microscopes are both delicate and expensive and must be handled with care.
1. Always carry the microscope with two hands — one supporting the base and the other on the arm.
2. Avoid stretching the wire of the lamp across a walkway.
3. Keep the stage clean and always use a glass slide for specimens(样本).
4. To avoid crushing the glass slide when focusing, begin with the lens close to the specimen and gradually back off to focus.
5. Keep the microscope covered to prevent the dust while it is being stored.
HOW TO USE THE MICROSCOPE:
1. Plug(接通电源) in the lamp.
2. Place a sample of what you wish to observe on a slide.
3. Adjust the mirror so it reflects light from the room up into the objective lens. When the mirror is correctly adjusted, a complete circle of light iwll appear when you look through the eyepiece.
4. Place your slide with the specimen directly over the center of the glass circle on teh stage. If it is a wet slide, be sure the bottom of the slide is dry.
5. With the LOW POWER objective leans placed over the slide, use the coarse focus knob to lower the lens to the lowest point.
6. Look through the eyepiece with one eye while closing the other eye. Slowly raise the lens until teh focus is relatively clear.
7. Use the fine focus knob to fine -tune(微调)the focus.
8. Without changing the focus knobs, switch to the HIGH POWER objective lens. Once you have switched to HIGH POWER, use only the fine focus knob to make the image sharper.Which of the following is the correct way to use a microscope according to the text?

King to a science fiction adventure set in the year 3005.“A lot of the material is really mature,” Ms. Gardner said, talking about films by the New York City branch of Global Action Project, a media arts and leadershiptraining group.“The Choice is about the history of a family and Master AntiSmoker is about the dangers of secondhand smoke.”Dream of the Invisibles describes young immigrants’（移民）feelings of both belonging and not belonging in their adopted country.

Most young architects—particularly those in big cities—can only dream about working in a building of their own. And making that dream come true often means finding a building no one else seems to want, which is exactly what happened to David Yocum and his partner, Brian Bell. Their building is a former automobile electrical-parts firm in Atlanta. From the outside, it looks too old, even something horrible, but open the door and you are in a wide, open courtyard, lined on three sides with rusting（生锈的） walls.
In 2000, Yocum and Bell found this building in the city’s West End. Built in 1947, the structure had been abandoned years earlier and the roof of the main building had fallen down. But the price was right, so Yocum bought it. He spent eight months of his offhours on demolition（拆除）,pulling rubbish out through the roof, because it was too dangerous to go inside the building. The demolition was hard work, but it gave him time to think about what he wanted to do, and “to treasure what was there—the walls, the rust, the light,” Yocum said. “Every season, more paint falls off the walls and more rust develops. It’s like an art installation（装置） in there—a slow-motion show.”
Since the back building had been constructed without windows, an allglass front was added to the building to give it a view of the courtyard, and skylights were installed in the roof. The back of the building is a working area and a living room for Yocum and his wife. A sort of buffer (缓冲) zone between the front and the back contains a bathroom, a kitchen and a mechanical room, and the walls that separate these zones have openings that allow views through to the front of the studio and the courtyard beyond.
Yocum and Bell, who have just completed an art gallery for the city, feel that the experience from the decoration of their building, focusing on the inside rather than the outside, has influenced their work. It has also given these architects a chance to show how they can make more out of less. According to the passage, it isfor most young architects in big cities to work in a building of their own.
| A．easy |
| B．unnecessary |
| C．unrealistic |
| D．common |

Most people have heard of Shakespeare and probably know something of the plays that he wrote. However，not everybody knows much about the life of this remarkable man，except perhaps that he was born in the market town of StratforduponAvon and that he married a woman called Anne Hathaway. We know nothing of his school life. We do not know，for example，how long it lasted，but we presume that he attended the local grammar school，where the principal subject taught was Latin.
Nothing certain is known for what he did between the time he left school and his departure for London. According to a local legend，he was beaten and even put in prison for stealing rabbits and deer from the estate of a neighboring landowner，Sir Tomas Lucy. It is said that because of this he was forced to run away from his native place. A different legend says that he was apprenticed to a Stratford butcher，but did not like the life and for this reason decided to leave Stratford.
Whatever caused him to leave the town of his birth，the world can be grateful that he did so. What is certain is that he set his foot on the road to fame when he arrived in London. It is said that at first he had no money or friends there，but that he earned a little by taking care of the horses of the gentlemen who attended the plays at the theatre.

Napoleon, as a character in Tolstoy’s War and Peace, is more than once described as having “fat little hands.”Nor does he “sit well or firmly on the horse.”He is said to be “undersized,” with “short legs” and a “round stomach”.The issue here is not the accuracy of Tolstoys description—it seems not that far off from historical accounts—but his choice of facts：other things that could be said of the man are not said. We are meant to understand the difference of a warring commander in the body of a fat little Frenchman. Tolstoys Napoleon could be any man wandering in the streets and putting a little of powdered tobacco up his nose-and that is the point.
It is a way the novelist uses to show the moral nature of a character. And it turns out that, as Tolstoy has it, Napoleon is a crazy man. In a scene in Book Three of War and Peace, the wars having reached the critical year of 1812, Napoleon receives a representative from the Tsar (沙皇), who has come with peace terms. Napoleon is very angry：doesn’t he have more army? He, not the Tsar, is the one to make the terms. He will destroy all of Europe if his army is stopped.“That is what you will have gained by engaging me in the war!” he shouts. And then, Tolstoy writes, Napoleon “walked silently several times up and down the room, his fat shoulders moving quickly.”
Still later, after reviewing his army amid cheering crowds, Napoleon invites the shaken Russian to dinner. “He raised his hand to the Russian’s...face,” Tolstoy writes, and “taking him by the ear pulled it gently...” To have one’s ear pulled by the Emperor was considered the greatest honor and mark of favor at the French court. “Well, well, why don’t you say anything?” said he, as if it was ridiculous in his presence to respect any one but himself, Napoleon.
Tolstoy did his research, but the composition is his own. Tolstoy’s description of Napoleon in War and Peace is.
| A．far from the historical facts |
| B．based on the Russian history |
| C．based on his selection of facts |
| D．not related to historical details |
Napoleon was angry when receiving the Russian representative because.
| A．he thought he should be the one to make the peace terms |
| B．the Tsar’s peace terms were hard to accept |
| C．the Russians stopped his military movement |
| D．he didn’t have any more army to fight with |
What did Napoleon expect the Russian representative to do?
| A．To walk out of the room in anger. |
| B．To show agreement with him. |
| C．To say something about the Tsar. |
| D．To express his admiration. |
Tolstoy intended to present Napoleon as a man who is.
| A．ill-mannered in dealing with foreign guests |
| B．fond of showing off his iron will |
| C．determined in destroying all of Europe |
| D．crazy for power and respect |
What does the last sentence of the passage imply?
| A．A writer doesn’t have to be faithful to his findings. |
| B．A writer may write about a hero in his own way. |
| C．A writer may not be responsible for what he writes. |
| D．A writer has hardly any freedom to show his feelings. |
