    When thinking about placing a human being in space, one of the most important questions was how to design special clothing needed to protect a person from the dangers of the space environment. The cold of space will freeze skin in a short time. The fierce heat of the sun can cause serious burns. The lack of atmosphere can cause gases in the body to expand(扩大) and even burst. With no oxygen to breathe, a human being will die in only a few moments. Radiation from the sun is another risk in space. So is damage from small pieces of rock and objects like meteoroids (陨石).

    In 1933, an American flyer, Wiley Post, designed one of the first successful devices to protect a pilot at extreme heights. It was a large device that looked like a can surrounded the pilot's head. Astronauts in the American space agency (NASA) flew the first American space flights in the early 1960s. The clothing was similar to that invented by Wiley Post.

    Today, astronauts wear very different protective clothing. It lets them move, do useful tasks, and stay outside their spacecraft in comfort and safety for several hours. The spacesuit is called the shuttle extravehicular mobility unit or EMU. It was designed to endure longer and to permit more movement than earlier spacesuits.

    The EMU has a number of parts that an astronaut can link together by using only one hand, which makes it possible for each astronaut to select the parts that fit correctly.

    Nowadays, NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.

    Thanksgiving is an important festival in North America. We interviewed several students from the US and Canada. Here is what they have told us about their Thanksgiving experiences.

    Josie from New York, USA

    “In America, Thanksgiving is celebrated every year at the end of November. It is to remember the first group of people from Europe to live in America. When they first arrived, they found the environment strange. But they learned to survive after some native American friends showed them how to grow and find food. Thanksgiving is meant to be a traditional celebration.”

Todd from California, USA

    “Thanksgiving is the first day of Christmas shopping. That means we have four weeks to buy Christmas presents for our families and friends. For me and my friends, the most important part of the festival is the big football game on TV. The match is watched by millions of people all over America. Thanksgiving is seen as an exciting day for football!”

    Ian from Saskatoon, Canada

    “In Canada, Thanksgiving is held on the second Monday in October. On the Sunday before Thanksgiving Day, many people go to church. Thanks is given for all the good things that happened to them during the year. I always give thanks for the nice big turkey I'm going to have at the family dinner! Like all festivals, Thanksgiving is about food!”

    Katie from Maritimes, Canada

    “On Thanksgiving Day, we have dinner with all our cousins, aunts and uncles. It is always very busy. Sometimes we have two Thanksgiving dinners because we go to both our grandparents' houses. The dinner is usually attended by more than twenty people at each house! My mother and my aunts do all the cooking but the washing-up is done by me and my cousins. And that's not an easy job! But I don't mind because Thanksgiving is meant to be a time to give thanks.”

    Emoji might not be your first choice of communication in a disaster, but researchers feel they could make a difference during emergencies, where every second counts. Now, the Emoji-quake campaign is lobbying for an earthquake emoji to be added to the Unicode set — the standard group of icons available on digital devices worldwide. The campaign aims to find an earthquake-appropriate design to be submitted to Unicode.

    "Approximately up to one third of the world's population are exposed to earthquakes," explains University of Southampton seismologist (地震学家) Dr. Stephen Hicks, a founder of the campaign. "So we really want to be able to communicate to all of those regions, all of those different languages, and an emoji is an amazing way of doing that."

    Unlike many other weather and climate related events, where longer warning times or visible signs are available, earthquakes move incredibly quickly and are difficult  to measure while they are still occurring. Populations in areas like Japan and Mexico are dependent on earthquake early warning technology, which issues an alert on digital devices and broadcast media. "You may have seconds to get under a table or to protect yourself," explains Dr. Hicks. "That can be life saving in many cases. Naturally you don't want too much wording in the warning message."

    Pictographs (象形文字) and other visuals like emoji have a track record of being faster and easier to understand than written information. Dr. Sara McBride, a communications specialist, who is also part of the campaign, told BBC News, "Emoji can cross the boundaries of written languages, helping communicate valuable information to people who may struggle to read a certain language."

    The potential usefulness of emoji in emergencies could extend well beyond earthquakes. A team of designers also came up with emerji—an entire set of emoji dedicated to climate and environmental events.

    Stephen Hawking was a famous physicist. He was born in 1942. He died at his home on March 14h, 2018 in Cambridge, Britain.
    As one of the well-known physicists on space and time in the world, Hawking devoted his whole life to discovering the secrets of the universe, and he is called the King of the Universe. Since he was 21 years old, Hawking had been badly ill, but he didn't give up his hope of living. He went on to study at Cambridge University after graduating from Oxford University. In 1965, he got a doctor's degree. Then he worked as a professor at Cambridge University.

    Hawking was known for his work with black holes. He also wrote several popular science books. Although he didn't live as freely as others, he still felt he was happy and he was thankful to life. When Hawking was invited to China, he made speeches in some famous universities.

    From Stephen Hawking's whole life, we learn that no matter how bad life is, we should not lose hope. As he once said," Life is not fair, you just have to do the best you can in your own situation."

    Annette Larkins is an incredible woman who looks like a healthy 40-year-old, although she just turned 70. She follows a special raw diet and only drinks rainwater.

    She looks so young that people mistake her to be the daughter, when she's out with her husband of 54 years, but I suppose he isn't complaining.

    Mrs. Larkins says the secret to her beauty lies in her special diet, consisting of organic vegetables, fruits, seeds and nuts grown in her own garden; she calls it the "fountain of youth". The woman doesn't touch anything that has been cooked.

    And another strange thing she does is to collect rainwater, to keep her garden blossoming, but also to drink. But the residents of Miami-Dade County, Florida, didn't always have such a healthy lifestyle. In fact, she consumed meat regularly, as her husband used to own a meat factory way back in the 1960s. It was then that she decided to change her eating habits forever. And what a great decision that was. I mean, just look at her!

    When she started off, Mrs. Larkins was just looking for a few health benefits and never anticipated that she would look like a 40-year-old at the age of 70. Over the 27 years that she has been eating raw, Mrs. Larkins has written two booklets railed Journey to Health and also produced a DVD containing all her healthy secrets.

    Her husband, Mr. Larkins, wishes he had followed her example, because now he looks much, much older and also suffers from diabetes (糖尿病) and high blood pressure. He takes prescription medicine every day, but Annette doesn't even take an aspirin.
