Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. While the limits of a person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随机地) from population, it is likely that their degrees of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degrees of intelligence.

   A start-up company in California, called Zume, is testing machines that make pizza. The robot takes and shapes dough to create the base of the pizza. It then adds tomato sauce, cheese, meat or other toppings. Next, the robot places the uncooked pizza into a hot oven. A few minutes later, the pizza is ready. The pizza comes out the same each time. Zume says the robots work quickly and do not get sick. The robots do not get paid either.

Julia Collins is the company’s founder and chief executive officer (CEO) . Her business can spend money on better food products because it does not have to pay the robots. Zume is using robots to make pizza.

Charity Suzuki has bought the robot-made pizza. She likes its taste. “It’s delicious. It’s always hot and fresh when it comes. I mean it’s great that they’re making it, but I can’t tell the difference that it’s made by a robot versus a human.”

Other companies say they are developing robots so people can get higher quality food faster. But what about the jobs the robots are taking from humans?

Ken Goldberg is a professor at the University of California in Berkeley. He also directs the school’s automation laboratory. Goldberg says researchers have been working with robots for 50 years. He says that, while there has been progress, the jobs are not going to disappear right away. “I want to reassure (使放心) restaurant workers that the skills that they have are still going to be of value,” Goldberg said.

“We’re going to get rid of boring, repetitive, dangerous jobs and we’re going to free up people to do things that have higher value. There’s going to be amazing new ways of working that don’t exist yet but are going to be created.”

【小题1】Why can Zume devote more money to better food products?

A．It earns a lot by selling pizza.	B．It wants to create more robots.
C．It can save a lot by using robots.	D．It hopes to attract more customers.

【小题2】What can we know about the robot-made pizza according to Suzuki?

A．It really agrees with her.	B．It is hot and fresh all the time.
C．It is tastier than the man-made.	D．It is delicious and free of charge.

【小题3】What’s the benefit of robots’ making pizza?

A．They work efficiently.	B．They help sick people.
C．They need few payments.	D．They produce more food.

【小题4】What does Goldberg think of the jobs of restaurant workers?

A．Interesting.	B．Boring.
C．Dangerous.	D．Necessary.

   It is a familiar scene these days: employees taking newly laid-off co-workers out for a drink for comfort. But which side deserves more sympathy，the jobless or the still employed？On March 6，researchers at a conference at the University of Cambridge suggested it was the latter.

Brendan Burchell，a Cambridge sociologist，presented his analysis based on various surveys conducted across Europe. The data suggest that employed people who feel insecure in their jobs show similar levels of anxiety and depression as those who are unemployed. Although a newly jobless person's mental health may“bottom out”after about six months，and then may even begin to improve，the mental state of people who are continuously worried about losing their own job“just continues to get worse and worse”, Burchell says.

Psychologists support this theory by arguing that human beings feel more stressed during times of insecurity because they sense an immediate but invisible threat. Patients have been known to experience higher levels of anxiety, for example, while waiting for examination results than knowing what they are suffering from—even if the results are cancer. It's better to get the bad news and start doing something about it rather than wait with anxiety.  When the uncertainty continues, people stay in a nonstop“fight or flight”response, which leads to damaging stress.

But not every employee in insecure industries has such a discouraging view, Burchell says. In general, women get on better. While reporting higher levels of anxiety than men when directly questioned, women score lower in stress on the 12-item General Health Questionnaire, even when they have a job they feel insecure about losing.  As Burchell explains,“For women, most studies show that any job—it doesn't matter whether it is secure or insecure—gives psychological improvement over unemployment.”He supposes that the difference in men is that they tend to feel pressure not only to be employed, but also to be the primary breadwinners, and that more of a man's self-worth depends on his job.

【小题1】Why do researchers think the still employed deserve more sympathy?

A．They have to do more work since then.

B．They have no chance to find better jobs.

C．They have to work with inexperienced workers.

D．They constantly worry about losing their jobs.

【小题2】What is most likely to cause a“fight or flight”response?

A．Not having a paid job.

D．Pressure to work longer hours.

【小题3】What will the writer talk about following the last paragraph?

A．Advice on preparing for a job interview.

B．Advice on handling pressure from insecure industries.

D．Difference in men and women.

【小题4】What is the main idea of the passage?

A．Is it less stressful to get laid off than staying on?

B．Should more sympathy be given to the jobless?

C．Do employees bear more stress than ever before?

D．Do men or women show higher levels of anxiety?

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”
【小题1】The difficulty the team of engineers met with while making the robotic fly was that __________.

A．they had no model in their mind

B．they did not have sufficient time

   A new study says that the faces on Lego minifigures have become less happy and more often mad or sad. The study was designed to find out if the Lego characters have become grumpier over the years.

Christoph Bartneck works at the University of Canterbury in New Zealand. He loves Lego and even worked for the company in the 1990s. He worked with another researcher on the project. They looked at all of the 6,000 figures made between 1975 and 2010. They made a note of each figure’s facial expression: happy, grumpy, afraid, surprised or satL They discovered that while in 1980, all of the figures were described as “smiley”, and that by 1990, only about 80 per cent of them had been “smiley” . And by 2010, just 50 per cent of the figures had had a smile on their little plastic faces.

The researchers are wondering how the increasingly sad, angry and unhappy faces on the Lego figures will affect the children who play with them. “Children’s toys can have an important influence on children,” said Bartneck on the university’s website. While Lego hasn’t issued an official response to the study, Bartneck said he thought the reason why Lego was producing angrier-faced characters was that children wanted them. He said it was likely that people wanted Lego characters to have different expressions, rather than just being sunny all the time. He said most of the unhappy faces were on characters based on a specific theme such as Harry Potter or pirates (海盗).

Bartneck will present his findings at the International Conference on Human-Agent Interaction in Sapporo.
