【推荐1】A traditional curriculum (课程) is the most widely accepted form of education. It refers to a teacher-centered style of education which requires students to passively receive information taught by teachers.     1    , based on what they think will be useful for the next generation in their academic and social lives.

Different from a traditional curriculum, a progressive curriculum presents a different approach to education.     2    . Teachers cease to be the authorities that are spreading knowledge, but rather only facilitate students’ research and development. School is no longer preparation for life, but rather a part of life, a process of learning and discovering that will last throughout the life of every student. Basically, it’s a reform of traditional education.     3    , although it is becoming increasingly popular in many schools across the world.

    4    . Usually, classes in schools supporting a progressive curriculum are smaller than in those supporting a traditional one. This is to ensure that students get as much attention from teachers as possible. Besides, a traditional system is mostly theoretical—knowledge is taught through lectures, worksheets, notes, and textbooks, without much practical involvement.     5    . It encourages direct experience, play, and social interaction. Furthermore, a traditional system supports knowledge in many areas, subjects and classes, while a progressive system focuses on the main interests of students and gives very deep and detailed information about those subjects, focusing the education on those subjects that are most interesting to the students at hand.

Scientists at the Chinese University of Hong Kong have created a magnetic (有磁性的) slime robot! It can carry out tasks like fixing broken circuits (电路) and picking up objects. They also think one day it could be put inside the human body to do things like help find items that have been swallowed by accident.

Li Zhang and his workmates mixed a range of substances together to make the slime which can be controlled by an outside magnetic field. They also added a substance that coats the magnetic parts to make them non-toxic (无毒的) for use in the human body.

The team then tested how well the soft-bodied robot functions in a range of situations, including finding and surrounding a lost battery in a model stomach and moving along while holding onto a piece of wire and also getting through tiny gaps.

There are robots in existence which can successfully find and hold onto objects and others that can go through tight spaces, however there aren’t many that can do both. The robot can also heal (治愈) itself after being cut into pieces.

“You can first pull it to a great extent so it looks like a liquid. Then afterwards, you can roll it like an octopus’ arm to carry something,” Li Zhang said.

“However, before they can use the robot inside a real person’s body, the scientists will first need to come up with a way of knowing where the robot is and how it’s performing,” Pietro Valdastri from the University of Leeds said. It would also need to be tested to make sure the magnetic parts which are toxic on their own aren’t able to separate from the slime. “They need to ensure its safety through future trials, but it’s definitely a sound approach,” Valdastri added.

Columbia University mechanical engineers have designed a 3-D printer that can produce and cook dishes at the same time with details at the millimeter scale.

The proof-of-concept design, described in Science of Food, combines a multiwavelength laser cooker, roughly the size of five smartphones put together, with a microwave-oven-sized food printer. Beyond applying complex substance and presentation designs, this type of software-controlled setup could someday scan a QR code to automatically prepare dishes adapted to individual eating habits and dietary requirements, says Blutinger, lead author of the paper and a digital-cooking researcher at Columbia.

The new technology is “astounding”, says Megan Ross, a food scientist who studies 3-D printing at Ireland’s University College Cork and was not involved in the study. Ross notes that the design is still at an early stage and that many technical challenges still remain, such as preventing cross contamination (交叉污染) between layers of uncooked and cooked meat. Still, Ross is impressed by the device’s ability to produce foods outside the kingdom of traditional cooking. “Is this going to be sold in shops everywhere in the next few years? No,” she says. “But everyone has to start somewhere.”

Compared with 3-D-printed chicken cooked in a traditional oven, the laser-cooked chicken had nearly twice as much weight and size, the researchers found. “That chicken is going to be juicy,” says Liam Macleod, a Denver-based chef (厨师) and former 3-D food printing specialist at the Culinary Institute of America who was not involved in the study. Macleod does not think such technology will ever replace chefs, but it might “add a tool to their collection” to deliver a new sensory experience. “Cooking is a skill set that has been practiced and perfected for thousands of years,” he says. “It’s very exciting to come up with something new and unique that people haven’t experienced yet.”
