Dear Edward,   

    How are you doing? I just visited Machu Picchu in Peru today. I've never seen such a great place before. This place is so amazing that I want to share my feelings with you.

When I first got to Machu Picchu, I felt like I was walking in the sky. Even the clouds were just under my feet. Do you know how high Machu Picchu is? I was surprised that it was at about 2,500m. How could people build a city on such a high mountain? It must have been very difficult to move stones there.

Before the Europeans arrived, the Incas (印加人) were the last and the most modern society in the Andes (安第斯山). The Incas were afraid that the Spanish would find them, so they built Machu Picchu on an Andes plain (平地) as a secret city in the 14th or 15th century. As a result, the Spanish never found Machu Picchu.

An American explorer discovered Machu Picchu in 1911. For a long time before that, nobody even knew Machu Picchu was there. After Machu Picchu was found, it was called "The Lost City of the Incas". It is still a mystery why and how Machu Picchu was left and forgotten by everyone.

I just had a wonderful day. Especially, I will never forget the "goodbye boy" who was a local boy dressed in traditional Inca clothes. When we went down the mountain by bus, the boy waved goodbye to us until we were out of sight (视线). He shouted some words at us too, and I guess, it meant, "Goodbye, come back again soon!" Why don't you visit Machu Picchu someday? I am sure you will love this place as much as I do.

                                                                                                                                                                      Yours truly,

                                                                                                                                                                          Lynn

    Body language is the quiet, secret and most powerful language of all! It is said that our body movements communicate about 50 per cent of what we really mean while words themselves only express 7 per cent. So, while your mouth is closed, your body is just saying...

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are the monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little to one side.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture(姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't sit straight, with your shoulders inwards. This makes breathing more difficult, which in turn can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse your lips(噘起嘴唇). You might also use this position to hold back an angry comment you don't wish to show. However it will probably still be noticed, and people will know you're not pleased.

On 27th April 2022, NASA astronaut Jessica Watkins made history as she entered space on a SpaceX rocket. Dr Watkins is now the first black woman to serve on a long-term mission (任务) to the International Space Station(ISS).

Jessica is not only an astronaut, but also a geologist(地质学家). She was a member of the planning team for several of NASA's Mars missions. Her knowledge of geology helped decide rovers' paths on Mars.

In 2017, Jessica began a two-year programme to become a NASA astronaut. It helped her to prepare for her work in space. As part of that work, she took part in an underwater training mission. She lived in an underwater lab for nearly two weeks.

Jessica and the three other astronauts will spend six months on the ISS. Their job includes a number of scientific experiments. They will also help take care of the space station.

Before Jessica, only four other black women had gone on short-term missions into space. "I'm building on the foundation(基础) laid by them," said the astronaut. She hopes her work will set a good example for all children, especially black children. "You are well able to go on space missions and to achieve success!"
