1 . Your child is unique, but what all children have in common is natural curiosity and an innate(天生的) ability to learn. Our brains are active all the time, and a baby’s brain is the busiest of all. Research has shown that babies begin to understand language about twice as fast as they actually speak it. By exposing children to other languages at an early age, you are giving them the opportunity to make use of their natural ability to hear and recognize the sounds of other languages, and their ability to make sense of what they are hearing.
Communication is something that children do to help them achieve something else, and they are unaware of the large amount of learning taking place. They take everything in through their senses, making connections between what they hear, see, smell, taste and touch. As long as we provide the right conditions, their learning and development will take place in a natural way.
In your child’s early years, the emotional environment is just as important as the physical environment. Children learn when they feel secure, happy, valued and listened to. This is central to any learning experience in a child’s early years, including learning an additional language. Your child has a trial-and-error approach to their development, and making mistakes is a valuable part of the learning process. Their progress isn’t held up by a fear of getting something wrong, and very young children are simply working their way towards getting it right.
The long-term benefits of learning another language go beyond being able to communicate with others. Studies suggest that children learning an additional language tend to score better on standardized tests because learning languages develops listening, observation, problem-solving and critical thinking skills. These are skills that are of lifelong benefit, both personally and professionally. Encouraging children in a love of language at an early age prepares them well for school and for life.

2 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.
