Suppose that we lined up our roughly 14 million United States businesses in order of size, starting with the smallest, along an imaginary road from San Francisco to New York. There will be 4,500 businesses to the mile, or a little less than one per foot. Suppose further that we planted a flag each business. The height of the flag pole represents the yearly volume of sales (销量) , each $ 10, 000 in sales in shown by one foot of pole.
The line of flagpoles is a very interesting sight. From San Francisco to about Reno, it is almost unnoticeable, a row of poles about a foot high. From Reno eastward the poles increase in height until, near Columbus, Ohio - about four - fifths of the way across the nation - flags fly about 10 feet in the air.
But as we approach the eastern terminus (终点) , the poles suddenly begin to mount (升高) . There are about 300, 000 firms in the country with sales over $ 500, 000. These firms take up the last 75 miles of the 3,000 - mile road. There are 200, 000 firms with sales over $ 1 million. They take up the last 50 miles. Then there are 1, 000 firms with sales of $ 50, 000, 000 or more. They take up the last quarter of a mile before the city limits, flags flying at cloud height, 5 , 000 feet up .
At the very gate of New York, on the last 100 feet of the last mile , we find the 100 largest industrial firms . They have sales of at least $ 1.5 billion, so that their flags are already miles high. Along the last 10 feet of road , there are 10 largest companies . Their sales are roughly $ 10 billion and up : their flags fly 190 miles in the air , almost in the stratosphere (平流层) .
1.What is the author’s main purpose in this passage?
A.To tell the reason why the largest firms are in New York.
B.To show the geographical distribution (分布) of the United States businesses.
C.To provide a general idea of the size of businesses in the United States.

高二英语单项填空简单题查看答案及解析
I’ve been teaching college for many years, long enough to note the gradual relaxation of attention in matters of student dress. And I’ve long been used to the worn jeans, flip-flops and shorts. Still, I took note recently when one of my students showed up in pajama bottoms. I couldn’t help asking, “Did you just roll out of bed?” “Five minutes ago.” he responded.
I’m familiar with the school of thought that says that how students dress is not important, so long as they’re learning. This is much the same when they say “Grammar and spelling don’t matter, so long as they’re expressing themselves.” Perhaps. But I also wonder about the wisdom of blurring(模糊)the line between bed and desk. I should think that a careful consideration of clothes before entering a formal environment is a sort of visible reminder to oneself (and one’s teachers) that impressions are important and that we have come together to get down to business.
I suppose that I come from a time when there were “school clothes” and “play clothes,” and never did the two sorts meet. I grew up in a working-class family, to whom “looking sharp” was important. Personal appearance might have made the difference between getting and losing a job. So yes, I’m all for freedom of choice in matters of dress, and yes, I do want my students to be comfortable. But I also want to pay my respects to those students who believe that appearances matter.
I think of this lady I had in class a few years back. She was someone to whom science was never easy: She worked hard for respectable grades on every task. But I was impressed by how tastefully she dressed, day after day. When the course ended, I mentioned this to her. “You always looked so nice,” I remarked,“as if you were ready to take on the world.”
1.Which of the following statements is Not True?
A.“Looking sharp” is helpful in getting a job.
B.It is wise to blur the line between bed and desk.
C.Students are being more and more casually dressed.
D.The author believes we should pay some respects to our appearances.
2.What does the “school of thought” mean in paragraph 2?
A.a college that teaches thoughts B.a group of students and teachers
C.a way of thinking D.a branch of learning
3.What do we know about the lady in the last paragraph?
A.She had a talent for science.
B.The author was impressed by her casual dressing.
C.Her grades were not decent though she studied hard.
D.She was one of the students who believed that appearances matter.

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part -drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any; reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.
1.Watchers doubted if any of the vehicles could finish the race because .
A.they did not have any human guidance
B.the road was not familiar to the drivers
C.the distance was too long for the vehicles
D.the prize money was unattractive to the drivers
2.DARPA organized the race in order to .
A.raise money for producing more robotic vehicles
B.push the development of vehicle industry
C.train more people to drive in the desert
D.improve the vehicles for future wars
3.From the passage we know “robotic vehicles” are a kind of machines that .
A.can do effortlessly whatever tasks living thing can
B.can take part in a race across 142 miles with a time limit
C.can show off their ability to turn themselves upside down
D.can move from place to place without being driven by human beings
4.In the race, the greatest distance one robotic vehicle covered was .
A.about eight miles B.six miles
C.almost two miles D.about one mile
5.In the last paragraph, the writer implies that there is a long way to go .
A.for a robotic vehicle to finish a 142-mile race without any difficulties
B.for a little child who has just learned to walk to reach the cookie on the table
C.for a robotic vehicle to deal with a simple problem that a little child can solve
D.for a little child to understand the importance of wiping apple juice off its face

Try this: For an entire day, forget about the clock. Eat when you’re hungry and sleep when you’re tired. What do you think will happen?
You may be surprised to find that your day is much like most other days. You’ll probably get hungry when you normally eat and tired when you normally sleep. Even though you don’t know what time it is, your body does. These patterns of daily life are called circadian rhythms(生理节奏), and they are more than just habits. Inside our bodies are several clocklike systems that follow a roughly 24-hour cycle. Throughout the day and night, our inner clocks direct changes in temperature, body chemicals, hunger, sleepiness and more.
Everyone’s rhythms are different, which is why you might like to stay up late while your sister always wants to go to bed early. But on the whole, everyone is programmed to feel tired at night and energetic during the day. Learning about our body clocks may help scientists understand why problems arise when we act out of step with our circadian rhythms. For example, traveling across time zones can make people wake up in the middle of the night. Regularly staying up late can make kids do worse in tests.
“There is a growing sense that when we eat and when we sleep are important parts of how healthy we are,” says Steven Shea, director of the Sleep Disorders Program at Brigham and Women’s Hospital in Boston.
One way to learn about how our body clocks tick is to mess them up and see what happens. That’s what neurologist(神经病学家)Frank Scheer and his workmates did in a recent study. Staying up night after night, their studies suggest, could make kids extra hungry and more likely to gain weight. And regularly sleeping too little, Scheer says, may be one cause of the recent increase in childhood obesity.
1.What will happen if you forget about the clock according to the passage?
A.You will feel upset.
B.You will behave normally.
C.Your body will not know what time it is.
D.You will probably get hungry more easily.
2.Mike feels energetic at 12 midnight while Tom feels sleepy. What advice would be given by the writer?
A.Both should see a doctor. B.Tom should see a doctor.
C.Both should take it easy. D.Mike should have a watch.
3.How do Frank Scheer and his workmates study body clocks?
A.By seeing what happens when they are messed up.
B.By asking questions and collecting answers.
C.By studying people traveling across time zones.
D.By programming people with man-made clocks.
4.What will the writer most probably talk about next?
A.Other examples of what people will do when their body clocks go wrong.
B.Some effective medicines that can keep people from putting on weight.
C.The importance of eating healthy food.
D.What circadian rhythms are and how they work.

This summer, I was part of something that I have carried with me every day since. That was an experience that changed my life. The Kentucky YMCA has a program called Y-Corps, which are service trips of around 20 students. This summer, two trips were made across Kentucky, one down south and another trip up north.
I was on the Y-Corps service to the North in the Indianapolis, Indiana, and our trip began at the end of July. I had butterflies flying around me as my parents drove me to Louisville, where the Service to the North team would set off on a nine-day journey in a school bus. I knew some of the team members from previous Y-Conferences, but there were many that I had never met, and I had never participated in a service trip like this before. Thought I was nervous, I was also ready to try something completely out of my comfort zone. Once we loaded the bus with our lightly packed suitcases and sleeping bags, we said our goodbyes to our parents and departed for an adventure that changed all of our lives.
With the Kentucky Y’s motto: “Participate, don’t anticipate, we had no idea where we headed. Road signs were our only clue of where we would be stopping. We did service work at a Middle Way House in Indiana, a Detroit Market Garden, a Pennsylvania YMCA for an invasive species clean-up, the Upper Main Line Y in Pennsylvania to spend time with children at a summer camp, a Hurricane Sandy clean-up in Jersey Shore and the National Mall in Washington D.C. We slept on floors of local YMCAs that would take us in for a night, and some nights we didn’t have the opportunity to shower. We had late nights on the road driving from city to city, and early mornings to start the day journaling and reflecting on the day before.
Though we were physically exhausted from the hard work, we still enjoyed the time to experience the culture of the areas we were in.
1.For the author the Service Trip to the North is .
A.meaningful B.expensive C.valueless D.fruitless
2.The Service Trip to the North started off from .
A.Kentucky B.Indiana C.Louisville D.Indianapolis

Philo Farnsworth was a man who made it possible for one of the most important communication devices (设备)- television to be created. Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family's farm. He did very well in school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand.
One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world's best scientists were using special machines to try to make a kind of device to send pictures.
14-year-old Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons(电子)could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work.
Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it "light in a bottle".
Several days later, Philo told his teacher about a device that could capture (捕捉)pictures. He drew a plan for it, which he gave his teacher. Philo's drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo's early idea.
Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. In fact, experts say that probably only ten scientists in the world at that time could have understood his idea.
On September 7th, 1927, Philo turned on a device that was the first working television receiver. The image produced on the receiver was not very clear, but the device worked. In 1930, the United States government gave Philo patent documents. These would protect his invention from being copied by others.
1.How did Philo get the idea of inventing a television?
A.By learning from his science teacher.
B.By reading a story in a magazine.
C.By thinking hard on his own.
D.By using his knowledge about electrons.
2.The underlined word "it" in the fourth paragraph refers to .
A.a container sending pictures and sound through the air
B.a receiver that holds light and sends it on a line of electrons
C.a light box with a line of electrons in a bottle
D.a way to make electrons send pictures quickly
3.What can we learn about Philo?
A.His interest in science was raised by his teacher.
B.He made the first television receiver himself.
C.He received patent documents at the age of 24.
D.He found the famous scientists wrong after showing his teacher a plan.
4.We can infer from the text that Philo's idea .
A.was not recognized at first
B.was only understood by his teacher
C.was turned into a television receiver immediately
D.was widely used in all television equipment in 1927

I’m about to begin my fifth season of tree planting. Each year, around this time, I have mixed feelings about the job. Never have I loved a job so much while hating it with equal measure. I mainly plant trees on the coast of British Columbia and get paid about 35 cents a tree. The job can be profitable. It gives planters the opportunity to lead a roaming (漫游的) lifestyle, with a temporary duty to spend a few months filling their bank accounts. But there are many challenges.
In the early hours of the morning, we join our teams and travel along rough roads deep into the woodlands. When stepping out of the trucks, often in the pouring rain, we’re faced with a steep chunk of land that’s just been logged (砍伐). I step into the rain and fill my bags with hundreds of tiny trees. Experienced tree-planters treat this more like a sport than a job, thus lighting up the mood.
Once our bags are full, we immediately charge up that hillside before feeling reluctant to go. We jump from log to log, and if they roll out from under our feet, we grab onto whatever within reach and swing around like monkeys. We push through stinging bushes. We stumble and fall constantly, always pushing ourselves to go faster among groups of insects that we often breathe in.
While tree planting, I come across someone else, a self I thought I knew. It is a person I try to come to peace with on those hillsides, during those strange days of isolation (隔绝) and deep thinking.
Tree planting is a lab of self-examination and growth, where you face the worst and the best in your nature and push yourself as hard as you can. And, a new version of yourself awaits at the end of the experience.

2.What challenges will they meet when planting trees?
A.They feel reluctant to collect tiny trees.
B.Workers’ mood needs to be lighted up on the truck.
C.They will have to help each other when planting trees.
D.The conditions are really tough on the hillside.
3.In what way has the writer benefited most by planting trees?
A.He has smoothed away many difficulties.
B.He has discovered a whole new himself.
