In the past hundred years, the world’s attitude toward whales has changed a lot. The animals are no longer seen as frightening creatures and worldwide protection efforts have reduced whale hunting. Through careful observation, scientists have shown that whales are generally peaceful, playful creatures, and that they have a high level of intelligence.
But even now, some behaviour of whales is still a mystery. A lot of information gathered by whale researchers has raised new puzzles about the animals. Whales’ communication is particularly difficult to understand. Male humpbacks (also known as bulls) give off a sequence (一连串) of low moans（呻吟）, high screams and clicking noises. These noises are sometimes combined in songs that last as long as 30 minutes. And in a particular region, every male will sing the same song, making small changes every once in a while so that it evolves (逐渐形成) into a completely different song over time.
This behavior seems to be related to reproduction. During the mating (交配) season, a male humpback starts the long song sequence, stopping only to join a passing female whale (also known as a cow). Eventually, the bull and the cow may dive deep into the ocean, probably to mate. Male humpbacks’ songs are similar to what birds display to attract mates (配偶), except that the sound carries over many miles, attracting some other male humpbacks in the area. It’s very odd that a male would call his own competition to him, unless he actually wanted to test his strength against others. Some whale researchers believe that the songs are actually acoustic (听觉的) contests of strength.What can we infer from the first paragraph?

What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?
We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop.The second is the application of the special methods of thought and actionthat scientists use in their work.
What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious — he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, andlooks for relationships even if the data available seem to be unconnected. Moreover,he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.
He is a good observer, accurate, patient and objective (客观的) and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum (光谱).
He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.
Furthermore,he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
Lastly,he is full of imaginationsince he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore,he needs imaginationif he wants to guess how processes work and how events take place.
These seem to be some of the ways in which a successful scientist or technologist thinks and acts.Which of the following statements about a curious scientist is TRUE?
| A．He doesn’t find confidence and pleasure in work. |
| B．He is interested in problems that are explained. |
| C．He makes efforts to investigate potential connections. |
| D．He looks for new ways of acting. |
Which word can be used to describe the data that a good scientist uses?
| A．Complete | B．Objective | C．Complicated | D．Accurate |
What does the passage mainly discuss?
| A．Application of technology. |
| B．Progress in modern society. |
| C．Scientists' ways of thinking and acting. |
| D．How to become a successful scientist. |
Where is it possible to drive from Rome to Moscow, Madrid, Paris, Vienna, and Stockholm without going to Europe? The answer is in the state of Maine!
Throughout the United States there are many towns and cities that have been named after not only European cities but other countries as well, such as China, Poland, Norway, Sweden, and Denmark. Just how many New World place names are recycled from the Old World names has never been tallied, but one researcher found forty-one Londons, fifty-six Berlins, twenty-four Dublins, thirty-two Athenses, and twenty-seven Moscows, among others!
Reasons for European place names differ. Some were in memory of settlers’ former homes, others in honor of historic events. Founded in 1818 by John Coffee, Robert Beaty, John D. Carroll, and John Read, Athens is one of the oldest incorporated cities in the State of Alabama. The town was first called Athenson, and the name was then shortened to Athens, after the ancient city in Greece. More interestingly, some names were given by mistake. For instance, the people of Moscow, Kansas, wanted their city to follow the name of the explorer Moscoso. They shortened his name to Mosco, and an official in Washington, thinking the Kansans couldn't spell, added a ‘W’.Which of the following is true according to the passage?
| A．In the state of Maine there are many different European cities. |
| B．You can drive to many European cities from the state of Maine. |
| C．All the settlers in the state of Maine came from Europe. |
| D．The state of Maine has many cities named after European cities. |
The word “tallied” (Line 4, Paragraph 2) is closest in meaning to ________.
| A．built | B．believed | C．added | D．visited |
What might have made the official in Washington change Mosco into Moscow?
| A．Moscow was a world-famous city name. |
| B．He thought Moscoso would prefer Moscow. |
| C．He believed Moscow was a far better name. |
| D．He thought Kansans couldn't spell very well and made a mistake. |
The best title for the passage is ________.
| A．The Story of Moscow, Kansas |
| B．American Cities and Their Names |
| C．Interesting Names |
| D．Old World Place Names in America |
Crystal Ear
One day a friend asked my wife Jill if I wanted a hearing aid. “He certainly does,”replied Jill. After hearing about a remarkable new product, Jill finally got up the nerve to ask me if I’d ever thought about getting a hearing aid. “No way,”I said. “It would make me look 20 years older.”“No, no”she replied. “This is entirely different. It’s Crystal Ear!”

When it comes to success in business and success in life, there are few qualities as important as confidence.
People naturally have different levels of confidence. Some have a higher level of confidence than others do, but even those whose confidence is lacking can learn to build their level of confidence and reach their most important goals. Increasing self confidence is one of the most common reasons people give for seeking the help of psychologists and other professionals.
One of the many places where a greater level of confidence is useful is in the workplace. We all know how difficult it can be, for instance, to ask the boss for a raise. This process can be extremely difficult for those who lack confidence in their own abilities. After all, if you are unsure about your own abilities, how will you ever convince your boss that you deserve more money for the work you do?
Even if you are not asking for that big raise, having plenty of confidence in your abilities is important to success. If you are certain of your abilities, chances are that those around you, whether they are your coworkers, your colleagues or your superiors, will see that confidence, and that will help to assure them that you are the best at what you do.
Being thought of as the person to go to, and being seen as an expert in your chosen field, is naturally very important to success on the job. If you can make yourself the person people go to for guidance and advice, you will help to protect yourself from the ever present danger of downsizing. After all, if you are a recognized expert at the office, you will be regarded as an indispensable member of the team.
Having a high level of confidence, after all, does not mean overlooking the places where you could improve. Knowing what you do well and where you need help will help you enjoy increased success and confidence.What is the passage mainly about?
| A．The influence of confidence on one’s life. |
| B．The importance of confidence to success. |
| C．The difference of people’s confidence. |
| D．The judgment on one’s confidence. |
Psychologists and other professionals can offer help to those _____.
| A．who think their goals are hard to reach |
| B．who expect to give guidance to others |
| C．who want to ask the boss for a raise |
| D．who dream to be recognized experts |
What does the underlined word indispensable in Paragraph 5 probably mean?
| A．important | B．attractive | C．outgoing | D．energetic |
What message does the author want to convey in the last paragraph?
| A．To overlook one’s disadvantages. |
| B．To make full use of one’s advantages. |
| C．To have great confidence in one’s abilities. |
| D．To make objective evaluations of one’s abilities. |
“Migrant workers”(外来务工人员) is a familiar term for 17-year-old Shi Jian. Her father and uncle often talk about the problems surrounding this group of people. However, Shi cares more about the children of these migrant workers.
Last year Shi’s housekeeper’s daughter had to give up her schooling in Beijing because she would not be allowed to sit the national college entrance exam. She was forced to continue her high school education in her hometown in Sichuan Province.
Shi thinks the current law is unfair for migrant workers’ children, as it prevents them from studying at public schools, unless their parents pay huge sums. So, Shi decided to do a survey of migrant workers so that she could find some solutions to help solve the problem.
In the last six months Shi spoke to 186 migrant workers in Beijing. Her interviewees include babysitters, guards, keepers, supermarket clerks, house cleaners and construction site workers. Shi found out that 55 of them were parents. Among this group, only eight have children who attend schools in Beijing. The other 47 had to leave children with relatives in the countryside. However, 40 of the 47 would like to enroll(使入学) their children in city schools.
From her interviews, Shi found that the workers’ lowest income was 400 yuan each month. Over one-third earn a monthly wage of or below 1000 yuan. “Even schools for migrant workers’ children charge more than public schools. Morever, parents constantly worry about these schools closing or relocating,” she explained.
Shi has recently completed a report about her survey, in which she makes a series of recommendations. “The government can set up public schools for migrants’ children equal to schools for city children. Second, to offset(弥补) migrant workers’ very low pay, public schools should offer them special rates so they can afford their children’s tuition(学费).What drove Shi to do the survey of migrant workers?
| A．Her curiosity about migrant workers’ lives |
| B．She was asked to do a survey of migrant workers as part of a school project. |
| C．Her housekeeper’s daughter was forced to move to her hometown to continue studying. |
| D．She wanted to draw people’s attention and become famous |
According to Shi’s survey, most migrant workers’ kids _____.
| A．don’t live together with their parents |
| B．attend schools near their parents’ working places |
| C．have to help their parents support the family |
| D．always do better in schools than children from the city. |
All of the following prevent migrant worker’s kids from attending schools in cities EXCEPT___
| A．their parents’ low income |
| B．their lack of confidence to face the fierce competitions in city schools |
| C．school’s high tuitions |
| D．that schools for migrant workers’ children may close or relocate |
Shi suggested in her survey that ____
| A．more private schools for migrants’ children should be built |
| B．more money should be collected for migrants’ children |
| C．children’s tuition should be reduced |
| D．students from the city and the countryside should be encouraged to communicate more |
