A boy was sitting on the steps of a door one day. He had a stick in one hand,1in the other hand a large piece of bread and butter, which somebody had kindly given him. While he was eating it and singing a song happily, he saw a poor little dog quietly2not far from him. He called out to it, “Come here, poor dog!”

    Hearing this, the dog woke up, rose with its ears3and wagged its tail. Seeing the boy eating, it came near him. The boy held out to it a piece of his bread and butter. As the dog stretched out its head to take the4, the boy quickly drew back his hand and hit it5on the nose. The poor dog ran away,6loudly, while the cruel boy sat, laughing at the trick he had done.

    A gentleman, who was looking from a window on the other side of street, saw what the7boy had done. Opening the street door, he called him to8over, at the same time9up one dollar between the finger and thumb.

    “Would you like this?” said the gentleman.

    “Yes, if you10, sir,” said the boy, smiling, and he quickly ran over to seize the11.

    Just as the boy stretched out his hand, the gentleman hit12on the knee with an umbrella. “Why did you do that?” shouted the boy angrily. He made a very13face and cried, “I didn't hurt you, nor ask you for money.”

    “14did you hurt that poor dog just now?” said the gentleman. “It didn't hurt you, nor ask you for bread and butter. As you served it I have served you. Now, remember it can feel as well as you, and learn to behave15towards animals in future.”

    Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech" software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface(界面) — one with all the speed and flexibility(灵活) of voice. "

Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD(高清) movies every second. The problem is that the best way we have to get information out into the world-speech can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

Technology is going to have to get a lot more advanced before we can share a pure thought or feeling, but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish," Ms Dugan said.
