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.

When I was a child, I was never really very interested in nature. Then one day my aunt bought me a {#blank#}1{#/blank#} for my birthday. It was called Birding on Borrowed Time. When she gave it to me, I was a little {#blank#}2{#/blank#}. It didn't seem very interesting, and I wanted new games for my phone. My aunt made me promise {#blank#}3{#/blank#} it. So I did, and I loved it. I found it was so interesting that I {#blank#}4{#/blank#} forgot about time. In fact, I didn't do anything else {#blank#}5{#/blank#} I finished it-- no TV, no games, nothing. As soon as I finished the book,I went out and bought a pair of binoculars(望远镜).

After that, I {#blank#}6{#/blank#} watching birds was one of the most interesting things in the world. To watch the birds, I needed to read books to learn about birds. Now I know more birds' {#blank#}7{#/blank#} than before. I can tell what they look like, how they fly and where to find {#blank#}8{#/blank#}.

Watching birds is interesting but not {#blank#}9{#/blank#}. Sometimes I have to stay in one place for a long time, and I have to take heavy binoculars and cameras with me. But when you find a beautiful bird and {#blank#}10{#/blank#} photos of it, it is really exciting.

My pen friend is Lily. She lives in New Zealand. It's next to Australia. She is a smart girl. She likes football. She wants to be a football coach( 教 练 ). She goes to school on foot. She has a brother. His name is Jill. He is only five. He likes singing. Her father is a baseball player. Her mother is a reporter(记者). She works in a TV station(电视台). She is 40 years old She likes using computers. They both go to work by car. They are very happy. 

Last weekend, the four members of my family spent an excellent holiday at the Disneyland. And one thing made our visit seem 1 . 

We got to the front of the line at Space Mountain, only to find out that our little daughter Gloria couldn't take her 2 on the ride. It was our first time to be there, so we were too 3 to remember that ice cream was not allowed on the ride. 

Gloria started 4 and we all didn't know what to do. Then Tony, one of the staff(员工) members, came over. He bent down and told Gloria that he would 5 the ice cream for her and give it back to her when she finished the ride. Gloria said, " Really?" Then she gave Tony her ice cream, and enjoyed 6 on the ride. 

Half an hour later, we 7 . And sure enough, there was Gloria's new friend 8 " her" ice cream. And we knew what had happened, 9 we knew that an ice cream couldn't last for thirty 10 without melting on a summer afternoon in Florida. Tony knew clearly 11 we would get off the ride. He went to the nearest shop and 12 a new ice cream half a minute before we walked out of the exit(出口). Gloria said, "13 . " But I was sure she didn't know it was a 14 ice cream. 

Thanks so much for giving us 15 and making our visit pleasant!
