The Mysteries of Nazca
In the desert of Peru, 300 kilometers from Lima, one of the most unusual artworks in the world has mystified (迷惑) people for decades. (46) But from high above, these marks are huge images of birds, fish, seashells, all beautifully carved into the earth.
The Nazca lines are so difficult to see from the ground that they weren’t discovered until the 1930s, when pilots spotted them while flying over the area. In all, there are about 70 different human and animal figures on the plain, along with 900 triangles, circles, and lines.
Researchers have figured out that the lines are at least 1,500 years old, but their purpose is still a mystery. (47) However, it would probably be very tricky to land a spaceship in the middle of pictures of dogs and monkeys.
In the 1940s, an American explorer named Paul Kosok suggested that the drawings are a chronicle (记录) of the movement of the stars and planets. (48) later, an astronomer tested his theory with a computer, but he couldn’t find any relation between the lines and movements in space.
Another explanation is that the lines may have been made for religious reasons. British researcher Tony Morrison investigated the customs of people in the Andes Mountain and learned that they sometimes pray by the side of the road. It’s possible that in the past, the lines of Nazca were created for a similar purpose. (49) But the local people have never constructed anything this big.
Recently, two other scientists, David Johnson and Steve Mabee, have speculated that lines could have been related to water. Nazca is one of the driest places in the world and receives only 2cm of rain every year. While Johnson was searching for ancient water sources in the area, he noticed that some waterways built ancient people were connected with the lines. Johnson believes that the Nazca lines are a giant map of the underground water in the area. (50)
A. Other scientists are now searching for evidence to prove this.
B. A Swiss writer named Erich Von Daniken wrote that the Nazca lines were designed as a landing place for UFOs.
C. Scholars differ in interpreting the purpose of the designs.
D. The largest pictures may have been the sites for special ceremonies.
E. Seen from the ground, it looks like lines scratched into the earth.
F. He called Nazca “the largest astronomy book in the world”.

My Life at Renda
I learned very quickly that being a teaching assistant (TA) at the University of Iowa would be different from being a teacher at Renmin University.
(1) Eyes staring, mouths open, students examined my big nose, while I was writing my name on the blackboard.
At Iowa, when my first classes began, half of my students still hadn't arrived. When everyone finally found a seat, ringing cellphones and loud yawns (哈欠) interrupted my opening remarks. It is not that American students were disrespectful.
(2) They were, however, far more skeptical than the students I had at Renda. The truth is I couldn't fault them for their skepticism. Undergraduates at large US universities - especially freshmen and sophomores - often have several classes a semester handled by TAs. In some cases, the TA sets the course content.
(3) Most have good intentions, but very few are as effective as professors.
Every teacher has to confront obstacles to learning - no matter what the culture. Students who talk during lectures, students who cheat, students who question the grade they get for a paper or project - dealing with these is all part of the job.
(4)
The difference, I think, is that in the US I had to swallow more of my pride.
(5)
I had a responsibility to teach them, of course, but I had to do so indirectly -as a guide who himself had a few things to learn from the students.
A Back at Renda, I had walked into my first classes feeling like a celebrity
B In my students' minds, I had little to offer them, except perhaps some sample questions for the mid-term exam.
C In others, the TA works as a grader and discussion leader
D I encountered these in China, and I faced them in the US.
E On the other hand, being taught by a graduate student is not necessarily bad
F Most were polite, or at least, indifferent.

What is a Profit
Gross profit is the difference between what a business firm sells its product for and what it costs to produce that product. The merchant buys $200，000 worth of merchandise during the year and sells it for $270，000. His gross profit is $70，000. The percentage difference between his cost and the selling price is 35 percent，and he calls this markup.
Entrepreneurship is directly responsible for production. The business person (entrepreneur) takes a cue from consumers in deciding what they want - or， in the case of a new product， __1__.
Profit means different things to different people. According to some public opinion polls， many people are not sure what it is， but they are sure __2__. Workers may look at profit as an unfairly large payment to the entrepreneur that deprives them of a higher wage. The business person thinks of profit __3__. During negotiations before the settlement of the second baseball strike in August， 1985，the Players‘ Association claimed the owners had made profits of $91 million， an accounting firm said owner profits were $43 million， and the owners insisted they had lost $9 million. The truth was that all three were correct. The disparity in the figures was due to the fact that each group was defining profit differently. Let us now see if we can develop a more exact definition of what profit is.
Net profit is __4__——rent，wages，and interest-and setting aside money to allow for the loss due to depreciation (wearing out) of capital. Our merchant has to subtract from his gross profit his payments for rent ($6，000)， wages ($20，000)，interest on money borrowed ($1，000)， repairs and upkeep ($1，000)， taxes ($1，000)， electricity and other expenses $1，000. Expenses for operating the business come to $30，000. Gross profit is $70，000， and net profit is $40，000.
Economists have a narrower definition of what constitutes profit. They are concerned with payment for all the resources that have gone into production， __5__，like those listed above， or from inside the business.
Exercise：
A what profit really means
B it is too large and represents too much of the consumer‘s dollar
C whether they come from outside the business
D as the difference between total revenue and total cost
E what the business person has left after paying expenses
F what they might want

Price Planning
A price represents the value of a goods or service for both the seller and the buyer. Price planning is systematic decision making by an organization regarding all aspects of pricing.
The value of a goods or service can involve both tangible and intangible marketing factors. An example of a tangible marketing factor is the cost savings__1__. An example of an intangible marketing factor is a consumer‘s pride in the ownership of a Lamborghini rather than another brand of automobile. For an example to take place，both the buyer and seller must feel that the price of a goods or service provides an equitable value. To the buyer，the payment of a price reduces purchasing power __2__. To the seller，receipt of a price is a source of revenue and an important determinant of sales and profit levels.

No matter what it is called，__3__：monetary and non-monetary charges，discounts，handling and shipping fees，credit charges and other forms of interest，and late-payment penalties.

Monetary and non-monetary exchange may be combined. This is common with automobiles，__4__. This combination allows a reduction in the monetary price.
From a broader perspective，price is the mechanism for allocating goods and services among potential purchasers and for ensuring competition among sellers in an open market economy. If there is an excess of demand over supply，prices are usually bid up by consumers. If there is an excess of supply over demand，__5__.
Exercise：
A a price contains all the terms of purchase
B obtained by the purchase of a new bottling machine by a soda manufacturer
C where the consumer gives the seller money plus a trade-in
D available for other items
E prices are usually reduced by sellers
F price means what one pays for what he wants

2016职称英语教材-卫生类C级完形填空及参考译文1 第一篇Better Control of TB Seen If a Faster Cure Is Found The World Health Organization1 estimates that about one-third of all people are infected with bacteria that cause tuberculosis . Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis. Current treatments take at least six months. People have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University2 led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve. The World Health Organization reductions the DOTS3 program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development4 says its long-term goal is a treatment that could work in as few as ten doses. 1.找到速效治疗剂可以更好控制结核病 世界卫生组织估计全球有大约三分之一的人感染了导致结核病的病菌。大多数时候，这种感染是不活跃的。但是每年大约有八百万结核病病例，通常是在肺部。两百万人因此丧命。结核病发病率由于艾滋病的传播和抗药型结核病的出现而增加。目前的治疗至少需要六个月。患病者不得不每日服用多种抗生素药品。许多人在稍感舒适后就停止使用药品，这么做可能导致抗药性感染。公共卫生专家一致认为针对结核病的速效治疗剂将会更加有效果。现在有一项研究评估这种速效治疗剂究竟效力有多大。这项研究由美国哈佛大学国际卫生方面的教授率领。Joshua Salomon说，疗程较短的治疗计划可能不仅仅意味着更多病人被治好，也意味着将感染传给别人的病人会更少。 研究者们设计了一个数学模型来检测两个月治疗计划的效果。他们以东南亚目前的结核病情况来检验这个模型。科学家们发现两个月的治疗可以防止大约20％的新病例，也可能防止大约5％因结核病引起的死亡。这个模型表明，如果速效治疗剂可以在2012年前研发出来并大规模使用的话，减少结核病例在2012年到2030年间就可以实现。 世界卫生组织在1990年制定了DOTS计划，DOTS意指短期直接观察治疗。卫生工作者监督结核病人每天服药，以确信他们继续治疗。今年年初，一个国际组织同盟宣布了一项扩大DOTS的计划。这个十年计划也旨在资助新结核药品的研究。现在四种最常用的药品也有四十多年的历史了。全球结核病药物开发联盟宣称它的长期目标是找到一种治疗方法，可以通过十次剂量就效果。

The First Four Minutes最初四分钟 When do people decide whether or not they want to become friends?人们什么时候决定他们是否愿意成为朋友？During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, “Contact：The first four minutes" he offers this advice to anyone interested in starting new friendships：“Every time you meet someone in a social situation, give him your undivided attention for four minutes. (1) A lot of people's whole lives would change if they did just that. ”按列奥纳多?祖尼博士的书中所说是在他们相处的最初四分钟。在他的书《接触：最初四分钟》里，他向所有对开始新的友谊感兴趣的人们提出了这样的建议：“每次你在社交场合遇到什么人时，全神贯注地注意他四分钟。如果这样做了的话，他们的生活就会完全不同。”； You may have noticed that the average person does not give his undivided attention to someone he has just met. 你可能已经注意到了，一般人都不会全神贯注地注意一个他刚认识的人。(2) He keeps looking over the other person's shoulder, as if hoping to find someone more.他不停地往其他人身后看，好像要在屋里其他地方找到更趣的人似的。If anyone has ever done this to you, you probably did not like him very much.如果有人对你这样，你大概不会很喜欢他。

When something creates a sound wave in a room or anauditorium, listeners hear the sound wave directly from the source. They alsohear the reflections as the sound bounces off thewalls. floor, and ceiling. These are called the reflected wave or reverberant(反射)sound, which can be heard evenafter the sound is no longer coming from the source. The reverberation time of an auditorium isdetermined by the volume or interior size of the auditorium. It is alsodetermined by how well or how poorly the walls, ceiling, floor, and contents ofthe room (including the people) absorb sound. There is no ideal reverberation time,because each use of an auditorium calls for different reverberation. Speechneeds to be understood clearly; therefore rooms used for talking must have ashort reverberation time. The full-sound performance of music such ad Wagneroperas or Mahler symphonies should have a long reverberation time. The light,rapid musical passages of Bach or Mozart need a reverberation time somewherebetween. Acoustic problems often are caused by poorauditorium design. Smooth, curved reflecting surfaces create large reflections.Parallel (平行的）wallsreflect sound back and forth, creating a rapid, repetitive pulsing https://www.doczj.com/doc/7610827026.html,rge pillars (柱）and comerscan cause acoustic shadows as the sound waves try to pass around the object.Some of these

Similar to your bedside alarm clock，your internal clock2 runs on a 24-hour cycle. This cycle，called a circadian rhythm，helps control when you wake，when you eat and when you sleep. Somewhere around puberty，something happens in the timing of the biological clock. The clock pushes forward，so adolescents and teenagers are unable to fall asleep as early as they used to. When your mother tells you it's time for bed，your body may be pushing you to stay up3 for several hours more. And the light coming from your computer screen or TV could be pushing you to stay up even later. This shift4 is natural for teenagers. But staying up very late and sleeping late can get your body's clock out of sync with the cycle of light and dark5. It can also make it hard to get out of bed in the morning and may bring other problems，too. Teenagers are put in a kind of a gray cloud6when they don't get enough sleep，says Mary Carskadon，a sleep researcher at Brown University in Providence，RI7 .It affects their mood and their ability to think and learn. But just like your alarm clock，your internal clock can be reset. In fact，it automatically resets itself every day. How? By using the light it gets through your eyes.
