NASA’s Mars detector (探测器), Opportunity, succeeded in finding signs that water once existed on the planet. Opportunity landed on Mars in January. Scientists now believe that the planet could once have supported life.
This discovery was chosen by Science, one of the world’s leading magazines, as the most important scientific achievement of 2004 last Friday.
“This little, wheeled, one-armed box went around another planet and has done something no human has ever managed,” according to Science. “It has discovered another place in the universe where life could once have existed.”
“Although we still can’t say that life could have existed in this environment, it is now certain that there was water on Mars,” said Steve Squyres, one of the scientists working on the Mars mission. The evidence comes from pictures and chemical readings taken by Opportunity. It includes marks on rocks like those caused by flowing water on Earth and salty chemicals like those found in dried-out sea-beds. Scientists said the new evidence proved beyond doubt that water has existed on Mars. But it is still unknown whether the water on Mars was like an ocean or justice.
While Opportunity has not found any signs of life, the presence of water means life is possible. “In everything we know about life on Earth, there is no example without liquid water,” Squyres said. “So water is important for the search for life on Mars.”
Researchers agree that a future mission (任务) should bring back physical samples (样品). But some scientists worry about the risk that this could introduce dangerous foreign creatures to Earth. “The problem here is how to get the samples back,” Squyres replied. “I think it is our responsibility to limit any risk.”

An idea that started in Seattle's public library has spread throughout America and beyond. The concept is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.
In addition to encouraging reading as a pursuit(追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched(发起) the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.
In Chicago, the mayor(市长) appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity can be achieved. Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.
Ultimately, as Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process, or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
What is the purpose of the project launched by Nancy?

A．To invite authors to guide readers.

B．To encourage people to read and share.

C．To involve people in community service.

D．To promote the friendship between cities.

According to the passage, where would the project be more easily carried out?

A．In large communities with little sense of unity.

B．In large cities where libraries are far from home.

C．In medium-sized cities with a diverse population.

D．In large towns where agreement can be quickly reached.

The underlined words “shared a word” in Paragraph 5 probably mean .

A．exchanged ideas with each other

B．discussed the meaning of a word

C．gained life experience

D．used the same language

According to Nancy, the degree of success of the project is judged by.

A．the careful selection of a proper book

B．the growing popularity of the writers

C．the number of people who benefit from reading

D．the number of books that each person reads

It was graduation day at the university where I work and a beautiful day quite unlike the first graduation I attended as a young professor．On that cold day years ago, as we watched the students walking into the hall, one of my colleagues turned to me and said, "Graduation will be one of the happiest and one of the saddest time of your life．" At my inquiry, he answered, "Because the students you have gotten to know have to leave．"
As years went by, my previous confusion about my colleague's words no longer existed．When I came across naughty students, I have had to rethink why I chose to be a teacher．It obviously isn't the money．Once a former computer science student of mine called me, asking me if I wanted to have a change．He was working at Nintendo Corporation．His salary was higher than my current one, though I have more education and have worked for over a decade．With my programming skills, he said he could get me hired．I thanked him, but declined his kind offer．
A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework．She thanked me for being her teacher and said the things she had learned in my class—not about math, but about life—would be things she would remember long after the math skills had faded away．As I finished reading, I remembered why I had become a teacher．
Now, on this sunny graduation day, as I again observed the sea of blue hats and gowns, I did so with renewed dedication （奉献） and a deeper sense of satisfaction—I will always be grateful that I am a teacher．
Hearing his colleague's description of graduation for the first time, the author __________．

A．quite agreed with his colleague

B．was very puzzled

C．thought it very funny

D．was very sad

The computer science student called up the author because he___________．

A．wanted to inform the author of his present job

B．tried to persuade the author to work with him

C．wanted the author to share his joy and satisfaction

D．thought the author wasn't fit to be a teacher

The underlined part “blue hats and gowns” refers to___________．

A．university colleagues	B．graduates' clothes
C．life memories	D．decorations in the hall

The author wrote this passage to __________．

A．express his devotion to being a teacher

B．compare two different graduation ceremonies

C．talk about the meaning of graduation

D．give advice on how to be a good teacher

People from East Asia tend to have more difficulty than those from Europe in distinguishing facial expressions--and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly across a face as Westerners do, Easterners fix their attention on the eyes.
"We show that Easterners and Westerners look at different face features to read facial expressions," Jack said. "Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and neglect the mouth."
According to Jack and her colleagues, the discovery shows that human communication of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to reliably convey emotion in cross-cultural situations.
The researchers studied cultural differences in the recognition of facial expressions by recording the eye movements of 13 Western Whites and 13 East Asian people while they observed pictures of expressive faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral. They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made significantly more errors than Westerners did. "The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions," Jack said. "Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less."
In short, the data show that facial expressions are not universal signals of human emotion. From here on, examining how cultural factors have diversified these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.
