It is hard to predict（预言）how science is going to turn out, and whether it is really good science, it is impossible to predict．If the things to be found are actually new, they must be unknown in advance．You cannot make choices on this matter．You either have science or you don’t and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits．
The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature．Indeed, I regard this as the major discovery of the past hundred years of biology．It is, in its way, a clear piece of news．It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange the way ahead seems．In earlier times, they either pretended to understand how things worked or simply made up stories to give answers．Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered．Because of this, we are sorry．It is not so bad being ignorant（无知的）if you are totally ignorant; the hard thing is knowing in some details the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted．
But we are making a beginning, and there ought to be some satisfaction．There are probably no questions we can think up that can’t be answered, sooner or later．Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention．

A disheveled (头发凌乱的) man appeared in court Thursday on charges of murdering a Chinese woman whose fight with her attacker was seen on webcam(摄像头) by her boyfriend in China. Police refused to release any details about the crime or its possible motive.
The body of York University student Liu Qian, 23, of Beijing, was found Friday in her apartment in Toronto a few hours after her boyfriend witnessed the attack, police said.
She was found undressed from the waist down but there were no obvious signs of sexual attack or trauma (创伤) severe enough to kill her. Police say it may be weeks before the results of an autopsy (尸体解剖) are known.
Brian Dickson, 29, stood before the court in a wrinkled white shirt and blue jeans as a charge of first- degree murder was read out. He did not enter a plea. His case was held over until April 26.
Dickson was arrested Wednesday. Police only announced his name and his age and asked the media not to publish any photos of Dickson, saying it could compromise the investigation. Toronto police spokesman Tony Vella declined to respond to the request further.
Liu’s father, Liu Jianhui, who arrived from China after being informed of his daughter’s death, thanked authorities for their quick action.
“I sincerely thank the people concerned with my daughter’s case,” he told reporters after the arrest. “Our daughter was studying very hard.”
Police released no motive or details about Dickson, but one friend described the Toronto man as an aspiring actor.
Patricia Tomasi, a friend of Dickson’s, told The Associated Press that she acted in a play at a local theater in Toronto with Dickson in 2007.
“He doesn’t seem like the type but that’s what they always say,” Tomasi said. “He’s tall with boyish good looks. I don’t know much about him except that he wanted to be an actor.”
Dickson attended York University where he studied global politics, but did not earn a degree from there.
He later worked for the Atlantic Council of Canada (ACC), where he served as an assistant to the president Juilie Lindhout. According to his biography on a newsletter from the Atlantic Council of Canada, Dickson has also been a running instructor and has been involved with Developments in Literacy, a Pakistani aid organization that raises money for children in Pakistan.
A statement from the Atlantic Council of Canada on Thursday said it was not council policy to comment on staff, but it confirmed that Dickson had been an intern(实习生) with the council from September 29, 2008, until March 27, 2009.
Liu was chatting with her boyfriend, Meng Xianchao, by webcam at about 1 am. Friday when a man knocked on the door, police said.
Meng reported seeing a struggle break out between the two before Liu’s webcam was shut off. Meng contacted other friends in Toronto who in turn called police.
The victim’s father, Liu Jianhui, said his daughter studied at Beijing City University before moving to Canada, where she met Meng.
Liu Qian’s laptop computer, webcam and mobile phone were taken from the apartment the night of the attack, police said. Police said the online chat was on a live streaming camera and was not recorded, though investigators were trying to figure out if there was any way they could recover it.
York University, whose campus is located near one of Toronto’s rougher neighborhoods, is one of Canada’s largest universities with more than 53,000 undergraduate and graduate students. About 3,200 of York’s students come from more than 150 foreign countries, the university’s website says.

   The first characteristic of an educated man is the precision of the use of the native language. When one hears English well spoken, with pure diction, correct pronunciation, and an almost unconscious choice of the right word, he recognizes it at once. How much easier he finds it to imitate English of the other sort.

    When manners are artificial and forced, no matter what their form, they are bad manners. When, however, they are the natural expression of fixed habits of thought and action, and when they reveal a refined and cultivated nature, they are good manners. There are certain things that gentlemen do not do, and they do not do them simply because they are bad manners.

   Human beings for the most part live wholly on the surface or far beyond the present moment and that part of the future that is quickly to follow it. They do not read those works of prose and poetry which have become classic because they reveal power and habit of reflection and induce that power and habit in others. When one reflects long enough to ask the question how? He is on the way to knowing something about science.

    An educated man continues to grow and develop from birth to his dying day. His interests expand, his contacts multiply, his knowledge increases, and his reflection becomes deeper and wider. It would appear to be true that not many human beings, even those who have had a school and college education, continue to grow after they are twenty-four or twenty-five years of age. By that time it is usual to settle down to life on a level of more or less contented intellectual interest and activity. The whole present-day movement for adult education is a systematic and definite attempt to keep human beings growing long after they have left school and college, and therefore, to help educate them.

    The more visionary dreamer, however charming or however wise, lacks something that an education requires. The power to do may be exercised in any one of a thousand ways, but when it clearly shows itself, that is evidence that the period of discipline of study and of companionship with parents and teachers has not been in vain.
