Certain forms of AI are indeed becoming ubiquitous. For example， algorithms （算法） carry out huge volumes of trading on our financial markets， self﹣driving cars are appearing on city streets， and our smartphones are translating from one language into another. These systems are sometimes faster and more perceptive than we humans are. But so far that is only true for the specific tasks for which the systems have been designed. That is something that some AI developers are now eager to change.
Some of today's AI pioneers want to move on from today's world of "weak" or "narrow" AI， to create "strong" or "full" AI， or what is often called artificial general intelligence （AGI）. In some respects， today's powerful computing machines already make our brains look weak. AGI could， its advocates say， work for us around the clock， and drawing on all available data， could suggest solutions to many problems. DM， a company focused on the development of AGI， has an ambition to "solve intelligence". "If we're successful，" their mission statement reads， "we believe this will be one of the most important and widely beneficial scientific advances ever made."
Since the early days of AI， imagination has outpaced what is possible or even probable. In 1965， an imaginative mathematician called Irving Good predicted the eventual creation of an "ultra﹣intelligent machine …that can far surpass all the intellectual （智力的） activities of any man， however clever." Good went on to suggest that "the first ultra﹣intelligent machine" could be "the last invention that man need ever make."
Fears about the appearance of bad， powerful， man﹣made intelligent machines have been reinforced （强化） by many works of fiction﹣Mary Shelley's Frankenstein and the Terminator film series， for example. But if A I does eventually prove to be our downfall， it is unlikely to be at the hands of human﹣shaped forms like these， with recognisably human motivations such as aggression （敌对行为）. Instead， I agree with Oxford University philosopher Nick Bostrom， who believes that the heaviest risks from AGI do not come from a decision to turn against mankind but rather from a dogged pursuit of set objectives at the expense of everything else.
The promise and danger of true AGI are great. But all of today's excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And， having spoken to many of the world's foremost A I researchers， I believe there is good reason to doubt that we will see AGI any time soon， if ever.

Many years ago, when I was fresh out of school and working in Denver, I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register I said hello to an older couple who were also paying for gas.
I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.
I wrote him and his wife a thank-you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holiday meaningful.
Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the lights on all day, and the battery was dead. Then I noticed that the Friendly Ford dealership --- a shop selling cars --- was right next door. I walked over and found two salesmen in the show room.
“Just how friendly is Friendly Ford?” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.

For more than six million American children, coming home after school means coming home to an empty house. Some deal with the situation by watching TV. But all of them have something in common. They spend part of their time alone. They're called latchkey children, They're children who look after themselves while their parents work outside. Lynette Long was once the headmaster of an elementary school. She said, “We had a school rule against wearing jewelry. A lot of the kids bed chains around their necks with keys attached. 1 was often telling them to put them inside their shirts. There were so many keys that it never came to my mind what they meant.” Slowly , she learned they were house keys.
She and her husband began talking to the children who had them. They learned of the effect working parents had on their children. Fear is the biggest problem faced by the children at home alone. One in each three latchkey children the Longs talked to are reported to be scared. Many had nightmares and were worried about their own safety.
The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall under a bed, in a closet. The second is TV. They’ll often play it at high volume.
It ‘s hard to get numbers on latchkey children and most patents are slow to admit they leave their children alone.

One afternoon after school had finished , Peter and Jane were walking along the street. Suddenly they heard a big noise.
“Come on” shouted Peter.“That sounds like an accident. Let’ see what’s happened.”
They ran to where the noise came from. As soon as they got there, they could see what had happened. A small car had knocked into the side of a truck. The accident had happened in a quiet street with only four houses in it. Peter and Jane were the first ones to reach the site. No other people came.“We must be the only ones who saw the accident,” said Jane. They found that both the car driver and the truck driver were hurt.
“Peter,” said Jane,“ Run back down the road to Mrs Day’s house. Ask her to call the policemen and the ambulance. Hurry. I’ll stay here.”
Off went Peter as fast as he could. There was nothing Jane could do but wait. She knew that when people were hurt in an accident, they shouldn’t be moved. It wasn’t long before the police car and the ambulance arrived. The policeman got the car door open and they carried the man out. Then they got the truck driver out. The men weren’t seriously hurt, but they were both taken to the hospital. The policemen thanked Peter and Jane, “You were very good to act so quickly when you saw the accident. Thank you for all your help.”

About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn’t help overhearing parts of their conversation. At one point the woman asked, “So, how have you been?” And the boy who could not have been more than seven or eight years old replied, “Frankly, I’ve been feeling a little depressed lately.”
This incident stuck in my mind because it strengthened my growing belief that children are changing. As far as I can remember, my friends and I didn’t find out we were “depressed” until we were in high school.
The evidence of a change in children has increased steadily in recent years. Children don’t seem childlike any more. Children speak more like adults, dress more like adults and behave more like adults than they used to.
Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists. Why?
Human development is based not only on born biological states, but also on patterns of access to social knowledge. Movement from one social role to another usually involves learning the secrets of the new situation. Children have always been taught adult secrets, but slowly and in stages: traditionally, we tell sixth graders things we keep hidden from fifth graders.
In the last 30 years, however, a secret-revelation machine has been fixed in 98 percent of American homes. It is called television. Television passes information, indiscriminately, to all viewers alike, whether they are children or adults. Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures.
Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbols that must be memorized and practised. Children must read simple books before they can read complex materials.Traditionally, a child is supposed to learn about the adult world _________ .
| A．through touch with society |
| B．gradually and under guidance |
| C．naturally and by biological instinct |
| D．through exposure to social information |
In the author’s opinion, the phenomenon that today’s children seem adult like is caused by _____.
| A．the widespread influence of television |
| B．the poor arrangement of teaching content |
| C．the fast step of human intellectual development |
| D．the constantly rising standard of living |
Why is the author in favor of communication through print for children?
| A．It enables children to gain more social information. |
| B．It develops children’s interest in reading and writing. |
| C．It helps children to memorize and practise more. |
| D．It can control what children are to learn. |
What does the author think of the change in today’s children?
| A．He feels amused by the children’s adultlike behavior. |
| B．He thinks it is a phenomenon worthy of note. |
| C．He considers it a positive development. |
| D．He seems to be upset about it. |
As the new semester begins，millions of college students across the country are trying hard to remember how best to write a paper-or，more likely，how best to delay that paper．
Procrastination is the thief of time and a lot of students suffer from it．They can spend whole days in the library doing nothing but staring into space，eating snacks，surfing the Internet，watching videos and looking at their pretty peers sitting around them，who，most likely，are doing nothing either．
Paralyzed by their habit to procrastinate，they write micro blogs about their fears，asking their online friends if they sometimes have the same issue．But this does nothing to solve their problems．
According to a recent report by the BBC，95 percent of us procrastinate at some point and 20 percent of the world’s population are procrastinators，complicating their lives with their continual delaying of tasks．
Procrastinators like to find excuses to justify their behavior，but BBC columnist Rowan Pelling says they are all wrong．Many procrastinators tell themselves they are perfectionists who work best under pressure．Pelling says this is nonsense，as work done at the last minute is more likely to have mistakes than work done on time．
She says the behavior of procrastinators often makes them feel flustered and ashamed，inconveniences others，and annoys loved ones．
Fortunately，social scientists have made tireless efforts to understand this behavioral shortcoming and offer strategies to control it．Piers Steel，a Canadian social scientist and author of The Procrastination Equation，believes humankind is“designed”to procrastinate．Nevertheless，he suggests a couple of good ways to get through the task at hand．
The first one is obvious：Break the task down into small pieces and work your way through them methodically．
The second is clever：Give a trusted friend a sum of money and tell them that if you don’t complete the task you have undertaken by a specific time，they can keep it or donate it to a cause you hate.What does the underlined word“Procrastination” in the second paragraph refer to?
| A．A bad habit of putting work or tasks off． |
| B．A thief who steals time and money in college. |
| C．A college student who learns nothing． |
| D．A study way of doing nothing in the library. |
According to Rowan Pelling，we can learn that procrastinators .
| A．can find reasonable excuses for their behavior |
| B．are able to work best under pressure |
| C．are more likely to avoid mistakes at work[] |
| D．may upset themselves and their loved ones more frequently |
Which of the following may Piers Steel support?
| A．Human beings are not born to be procrastinators． |
| B．Complete your tasks or work step by step． |
| C．Give your trusted friend money and ask him to help you finish your tasks． |
| D．You can’t control procrastination but you can avoid it． |
What’she best title of the text?
| A．Who steals my time? |
| B．The solutions to procrastination |
| C．I’ll do it tomorrow，I swear! |
| D．Don’t do nothing! |
