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.

    In 1901, Karl Landsteiner, an Austrian scientist, discovered that there are four types of blood. These four blood types were named A, B, AB and O. People have one of these four types. Blood type O is the most common around the world. Blood type A is the second most common, and type AB is the least common. If people with type A blood are given type B blood, or people with type B blood are given type A blood, they will probably die.

    In 1927, a Japanese doctor, Furukawa Takeji, carried out research and came up with the idea that people with different blood types also had different personalities(性格). He said that people with type A blood are usually calm and serious; people with type B blood are curious, cheerful and outgoing; people with type O blood are generous and trustworthy; while those with type AB blood are often caring, original and careful.

    More recently, a doctor in the United States wrote a book that links blood types and what people eat. For example, his book suggests people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book, Eat Right for Your Type, has been a hit with people who want to lose weight. However, Dr. Peter D' Adamo believes that eating food that matches a person's blood type can help them lose weight. He thinks it will make the person healthier in other ways, too.

On May 15, 2023, the Activity of Choosing People Who Moved Liangshan（凉山） in 2022 was held in Xichang. Ten people  {#blank#}1{#/blank#}  the proud prize. Among them was Lou Se'er whose four children got into the famous universities in China. Two of them are studying in Tsinghua University. He was given a special prize by the government on October 31st, 2022. It's impossible for him to get such special prizes  {#blank#}2{#/blank#} the great effort.

Luo and his wife live in a small mountain village in Butuo. They have a common and hard life as most other  {#blank#}3{#/blank#} in their neighborhood. They have little education, but how can they bring up four excellent children? Luo told reporters about his "secrets of  {#blank#}4{#/blank#}  education." "I hope my children can get more education and have a better future." said Luo. "My wife and I faced lots of challenges and difficulties. We don't know  {#blank#}5{#/blank#} to read or write. We can hardly count."

They  {#blank#}6{#/blank#}  realized the importance of education for their children. They made up their minds  {#blank#}7{#/blank#}  them to good schools. They can't help their children with studying at home during weekends, summer and winter vacations. The children have to learn by  {#blank#}8{#/blank#}  and sometimes the elder brothers helped their younger brother and sister. They studied very hard and made great progress in examinations. "My all children are in good universities. In fact, there is no  {#blank#}9{#/blank#} . It's just a wholehearted decision, I together with my wife will support them all the time as long as they need. We think hard work plays a very  {#blank#}10{#/blank#} role towards success." added Luo.

Many people are touched by the story about the poor family—parents with little education and four  {#blank#}11{#/blank#}  children. They believe that the Luos' life must become better and better.

Two years ago, Tom was 14 years old. He often played computer games after school. On weekends, he watched TV all day and he never 1 any exercise. What's more, he ate lots of junk food, such as hamburgers, French fries, cola. 2 that time, he often had a fever and couldn't sleep 3 . One year ago, There was something wrong with his heart. His parents worried about 4 . And they wanted 5 him to see a doctor. After 6 doctor examined (检查) carefully, he said, "If you go on like this, you will have to stay in hospital. You 7 eat more vegetables and less junk food. You also need to do exercise regularly (有规律地), 8 it is good for your health." From then on, Tom changed his habits. Now He often spends some time 9 sports with his classmates after school. And he also eats 10 food. He is becoming healthier and healthier. How happy his parents are!

Do you know what is the smallest bird in the world? The answer is" The hummingbird (蜂鸟)". How small is it ? Even the largest one in western South America is only about 20cm long. Its body weigh about 20g. The smallest hummingbird is the bee hummingbird. It lives in Cuba. It is about 

5.5cm long and weighs about 2g. They are the smallest living birds. The funny thing is that people often mistake them for bees.

Although hummingbirds are small, they have strong bodies. They are good at flying as well. One more interesting thing fact is that the humming bird is the world's smallest dinosaur(恐龙)." Birds are just one lineage(家系) of dinosaurs that happened to live to present. Julia Clark, a scientist at North Carolina State University, told Live Science.
