一项新的研究表明，成年人学习新语言时，先听语音的旋律和节奏，比先学习文字更有效。研究人员让捷克成年人听毛利语，然后测试他们区分毛利语和马来语的能力。结果显示，单纯聆听的参与者表现更好，而阅读字幕反而降低了他们的识别能力。这表明，成年人学习语言时，应该像婴儿一样，先注重语音的整体感，再学习文字，这或许能更好地激发大脑的语言学习机制。

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
