The Chinese language differs from Western languages in that, instead of an alphabet, it uses characters which stand for ideas, objects or deeds. Chinese words are formed by putting together different characters. In many cases, a single character can also make up a word. The history of the Chinese language can be examined by looking at how these characters developed.
Chinese writing began thousands of years ago. According to an ancient story, a man named Cang Jie invented Chinese writing. One winter day while he was hunting, he saw the tracks of animals in the snow and observed that the appearance of each one was different. Then he had the idea that he could use different shapes to represent different objects. The first Chinese characters were drawings of physical objects. Some characters have been simplified and others have been made more difficult over time. However, as a whole the characters have developed from drawings into standard forms.
Not all characters were developed from drawings of objects. Sometimes to express ideas, some characters were made by combining two or more characters together. Other characters were developed for directions and numbers. It is easy to distinguish their meanings by looking at them.
Though these kinds of characters indicate meanings, one of their shortcomings is that they do not show how they should be pronounced. Therefore, a method was developed to have one part of a character indicate the meaning and the other suggest the pronunciation. Many Chinese characters used today were made this way.
In the 1950s the Chinese government introduced simplified Chinese characters and now they have widespread use in China’s mainland.

In 1929, a peasant in Sichuan Province uncovered jade (玉器) and stone artifacts(手工艺品) while repairing a ditch(沟渠) located about 24 miles from Chengdu. But their significance wasn’t understood until 1986, when archaeologists unearthed two pits(大坑) of Bronze Age treasures. The discovery suggests an impressive technicality(手工技艺), said Peter Keller, a geologist and president of the Bowers Museum in California, which is currently hosting an exhibit of some of these treasures.
The treasures came from a lost civilization, now known as the Sanxingdui, a city on the banks of the Minjiang River.
“It’s a big mystery,” said Keller, who is not involved in the current study.
“Archaeologists now believe that the culture disappeared sometime between 3,000 and 2,800 years ago,” Niannian fan, a river science researcher at Tsinghua University in Chengdu, China, said.
“The current explanations for why it disappeared are war and flood, but both are not very convincing,” Fan told Live Science.
But about 14 years ago, archaeologists found the remains of another ancient city called Jinsha near Chengdu. The Jinsha site, though it contained none of the bronzes of Sanxingdui, did have a gold crown covered with fish, arrows and birds similar to golden objects found at Sanxingdui. That has led some scholars to believe that the people from Sanxingdui may have relocated to Jinsha.
Fan wondered whether an earthquake may have caused landslides that dammed the river high up in the mountains and rerouted it to Jinsha. That catastrophe may have reduced Sanxingdui’s water supply, spurring its people to move.
And some historical records support their assumptions. In 1099 B.C., ancient writers recorded an earthquake in the capital of the Zhou Dynasty, in Shanxi Province, Fan said. Though that spot is roughly 250 miles from the historic site of Sanxingdui, the latter culture didn’t have writing at the time. So it’s possible the earthquake epicenter(震中) was actually close to Sanxingdui－but it just wasn’t recorded there.
Around the same time, geological sediment(沉积物) suggest massive flooding occurred, and the later-han Dynasty document The Chronicles of the Kings of Shu records ancient floods pouring from a mountain in a spot that suggests the flow being rerouted, Fan said.
Together, the findings hint that major earthquake triggered a landslide that dammed the river, rerouting its flow and reducing water flow to Sanxingdui, Fan said.

I was born at Blunderstone, in Suffolk, in the east of England, and was given my poor father’s name, David Copperfield. Sadly, he never saw me and died six months before I was born. My early childhood was extremely happy, as my beautiful mother and kind Peggotty took care of me. But when I was about eight, a shadow passed over my happiness. My mother often went out walking, in her best clothes, with a gentleman called Mr Murdstone. He seemed to be very fond of my mother. But I knew that Peggotty did not like him.
A few months later Peggotty told me that my mother was going to have a short holiday with some friends. Meanwhile Peggotty and I would go to stay with her brother Daniel in Yarmouth，on the east coast, for two weeks. I spent a wonderfully happy two weeks there, playing all day on the beach with Emily, and sleeping in my own little bed on the ship. I am sure I was in love with little Emily in my childish way, and I cried bitterly when we had to say goodbye at the end of the holiday.
But on the way home to Blunderstone, Peggotty looked at me very worriedly. ‘she said suddenly in a trembling voice.‘I must tell you—While we’ve been away, your dear mother—has married Mr Murdstone！He’s your stepfather now!’
I was deeply shocked. I could not understand how my mother could have married that man. And when we arrived home, I went straight to my room and lay sobbing on my bed, which made my poor mother very unhappy too. As she sat beside me, holding my hand, Mr Murdstone suddenly came in.
What’s this, Chara, my love?’ he asked sternly. ‘Remember, you must be firm with the boy！I’ve told you before, you’re too weak with him!’ And when mother left the room, Mr Murdstone whispered angrily to me, ‘David, do you know what I’ll do if you don’t obey me？I’ll beat you like a dog!’ I was still very young, and I was very frightened of him. If he had said one kind word to me, perhaps I would have liked and trusted him, and my life would have been different. Instead, I hated him for the influence he had over my dear mother, who wanted to be kind to me, but also wanted to please her new husband．

From self-driving cars to deep sea explorers, more and more of humans’ tasks are being taken over by robots. But technology doesn’t stop there. In mid-August, reported the BBC, scientists from Cambridge University developed a robotic system that meant a robot could “build other robots, each one better than the previous(以前的) generation”.
The BBC noted that “those concerned about machines taking over the world shouldn’t worry”.
However, over 1,000 scientists and numerous artificial intelligence (AI, 人工智能) researchers－including UK astrophysicist Stephen Hawking and Apple cofounder Steve Wozniak of the US-brought the danger of fully autonomous weapons(自主武器), known as “killer robots”, to our attention earlier this summer.
“If any major military(军事的) power pushes ahead with AI weapon development, a global arms race is inevitable(不可避免的),” warned an open letter released at the International Joint Conference on Artificial Intelligence held in Buenos Aires, Argentina.
Unlike drones(无人机), which need a human hand, this kind of robot would have some decision-making abilities and the ability to act by itself. While what the BBC called these “solders that never sleep” could help reduce battlefield deaths, they might also make countries more likely to go into battle, which would lead to more deaths overall, noted the scientists. The risks, they said, could be far greater than those posed by nuclear weapons.
Scientists called for a “ban on offensive(攻击性的) autonomous weapons beyond meaningful human control”, reported The Huffington Post.
In fact, in an interview with the BBC in 2014, Hawking warned that the “development of full artificial intelligence could spell the end of the human race”.
And according to the BBC, many leading thinkers have been thinking about the AI-powered killing machine of the not-too-distant future. “Killer robots could be here within years, not decades,” as Stuart Russell, professor of computer science at UC Berkeley, US, put it.
Authorities are gradually waking up to the risk of robot wars. Last May, for the first time, the United Nations brought governments together to begin talks on so-called killer robots in a hope of stopping such weapons while there is still time.
Meanwhile, there are scientists who are less worried. They believe all technologies have potential(潜力) for being used for good and evil ends, and argue that the ban called for by the open letter could close the door to developing AI technology that could save lives. “Technology can clearly do better than human beings in many cases,” Ronald Arkin, dean at the Georgia Institute of Technology in Atlanta, US, told The Christian Science Monitor. “If we are willing to turn over some of our decision making to these machines, we may actually get better outcomes.”
1.What does Steve Wozniak think the future robot technology might produce?
A. Artificial Intelligence. B. Autonomous weapons.
C. Soldiers that never sleep. D. Killing machines.
2.The underlined word “spell” in Paragraph 7 is closest in meaning to “______”.
A. cause B. prevent
C. reach D. change
3.What does Stuart Russell mean by saying “killer robots could be here within years, not decades.”?
A. Killer robots will visit UC Berkeley, US sooner than expected.
B. Killer robots will be produced and used sooner than expected.
C. Killer robots will speed up the development of AI in the near future.
D. Killer robots will kill these scientists in the near future.
4.What is the main idea of the text?
A. More and more of humans’ tasks are being taken over by robots.
B. Robots have decision-making abilities and the ability to act by itself.
C. Scientists called for a ban on the development of robot technology.
D. All technologies have potential for being used for good and evil ends.
