Philip likes dogs. He asks his parents to1a dog for him. but his parents can't do the because Philip's grandma doesn't like dog.

    Philip says to his grandma, "I will2the dog out of your way." Grandma says yes. On Friday evening,Philip3his dog. He is so4and he calls his dog Fifi.

    One day Grandma says she will watch TV in her room and that she doesn't want Philip to disturb (打扰) her, 5Philip plays with his dog in his room. After some time, Fifi6the door (门) of Grandma's room. and begins barking (吠叫) at the door. Philip tells Fifi not to bark. But Fifi doesn't7.

    Philip's father8something is wrong (不正常的), and then he opens (打开) the door and sees Grandma on the floor (地板). They9her to the hospital (医院) quickly.

    After Grandma leaves hospital, she thanks Fifi for saving (救) her10and says that Fifi is now one member (成员) of her family.

    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.

What do pandas，tigers，whales，lions and wild camels have in common （共同的）？They are all endangered（濒临灭绝的）. Here are the reasons. 

Hunting：For centuries，people hunted elephants for their tusks，killed tigers for their fur，and caught many other animals for their meat. 

Foreign animals：In 1505，some people discovered a beautiful island named Mauritius in the Indian Ocean. People brought dogs，pigs，monkeys and rats with them，but this was bad news for dodo birds. The birds did not have natural enemies （天敌） before. They ate fruit that fell from trees and built their house on the ground. But when people came，dodo birds were in big trouble—men killed them for their meat，and the new animals broke their homes and ate their eggs. The number of dodo birds became smaller and smaller and finally extinct. The last dodo bird was killed in 1681.

Loss of living space：People cut down forests for farming and building houses. People build dams （水坝） to make sure they have enough water. While we make our lives comfortable，other animals have less and less space. 

When Chandra went into Books ‘n' More, she noticed that there was no one else in the bookstore. The last four or five times she had stopped in here, she had also been the only customer. 

That night, Chandra told her family about the situation at the bookstore. Her brother Pete said, "The bookstore needs more people. How about starting a book club? People could meet in the store to discuss a book they've all read. If they buy it at the store, they'll receive a discount. "

"That's great!" Chandra said excitedly. "How about having some writers come and do a book signing? I even have an idea for the first writer. Mr. Fletcher, my math teacher, writes children's books. I'm sure he would be willing to help. I could put up fliers about the event at my school. "

The next day, Chandra shared her thoughts with Mrs. Lee, the bookstore owner. Mrs. Lee seemed unsure at first, but by the time Chandra finished, she was smiling. "I'll try your ideas, but I need some help. Someone will have to lead the book club discussions. Also, I'll need help advertising these events because I've never been good at such things. "

Chandra promised that she would help. She asked Mr. Fletcher if he would read and sign some of his books at Books ‘n' More, and he happily agreed. A date was chosen, and Chandra threw herself into the preparations. She personally invited all her friends, the other teachers, and even the school headmaster. 

Finally, everything was ready for the big night. Mrs. Lee opened the event. "Before I introduce tonight's writer, I must thank a young lady named Chandra Phillips. This exciting evening was mostly managed by her. If she were a little older, I would have her as my advertising director, " said Mrs. Lee. The crowd laughed and clapped. As Mr. Fletcher began to read from his latest book, Mrs. Lee took a seat next to Chandra. 

"Could I really work here someday?" Chandra asked. Mrs. Lee nodded with a smile. Chandra tried to listen to Mr. Fletcher, but her mind swam with even more ways to help Books ‘n' More be successful. After all, she had to protect her future job!

The key to learning a new skill isn't necessarily how many hours you spend practising, but the way you practise. Scientists have found that by simply changing your training method, you can keep your 1 more active in the learning process and spend less time reaching the required standard. People think simply 2 a skill—for example, practising the same piece of music on the piano or playing the same level in your game over and over again—is the best way to learn it. Instead, it turns out that there might be a 3 way to level up. 

Recently, researchers got 86 volunteers to learn a new 4 —moving a cursor(光标) on a computer screen by pressing a small device, 5 using a mouse. The volunteers were divided into three groups, and 6 spent 45 minutes practising the skill. Six hours later, one of the groups was asked to repeat the same training exercise again, 7 another group to perform a different version(版本) that required a different pressing8 to move the cursor. The third group was 9 asked to complete the first training, acting as a control(对照组). 

In the end, everyone was 10 on how they could perform the new skill. As a result, the group that had repeated the original(原来的) training did 11 on the test compared to the one that had had mixed training and trained in new areas—in fact, the group that had 12 their training method did twice as well as the group that had repeated the original training. 

So how does that work? The researchers believe it's due to something called reconsolidation(重新合并), which is a process: 13 are recalled and changed with new knowledge. "Our results are important 14 little was known before about how reconsolidation works in relation to skill development. This shows simple training method changes can 15 more rapid and better skill gains, " said Celnik.
