Taking part in colourful activities is an important part of school life! Which activity has impressed you most during the past three years? What will students in Mount Rose Middle School do? Please read the following article!

(Science and technology makes our school life easier and better than before! When your teacher gives lessons with his phone or iPad, Bluetooth does help a lot. What is Bluetooth? Read the article and find it out!)

If you look around the room you are in right now, you’ll probably notice a number of electronics. But can you imagine if they all had to be joined together by wires (电线)? Picture the wire snaking along the floor, for example, from your smartphone to your speaker, or connecting your game controller to the computer screen, meaning you could never sit more than a couple of meters away from it. A world of electronics connected by wires wouldn’t just be untidy, but a possible danger, too. That’s where Bluetooth comes in. We’ve all heard of it—but what exactly is it?    

Bluetooth is a method of short-distance（短距离）wireless communication between electronics that makes use of the power of radio waves. The idea was first thought of by Dr. Janp Haartsen at Swedish mobile company Ericsson in 1994. Things really stepped up in September 1998 when the Bluetooth Special Interest Group(SIG) was set up to develop and spread the technology. Bluetooth 1.0 came out in 1999, and a year later it began to be used in mobile phones and desktop computers. Now Bluetooth has become an increasingly popular way of solving the problem of more and more electronics needing to be connected without having to connect everything together with wires.

But if you look at the remote control（遥控器）you use to choose the program on TV, you might rightly ask yourself why Bluetooth was such a big deal. After all, connecting objects with infrared signals（红外信号）which can’t be seen had been done before. The problem with remote controls is that they need to keep what is called “line of sight”. If something is standing between the remote control and receiver, it won’t work. Because Bluetooth uses radio waves, the things standing in the way are no longer a problem.

Since its creation in the late 1990s, the technology has become more and more improved and widely used, with the 4 billionth Bluetooth objects shipped in 2020.

You must have attended many different courses at school.Do you still remember the space lesson hosted by Wang Yaping?

On the afternoon of March 23, 2022, Chinese astronauts on board China’s Tiangong space station gave a science lesson 400 kilometers above Earth. It was a great success. Do you still remember the first space lesson hosted by Wang Yaping in 2013? Helped by the other two astronauts, she gave the lesson to more than 60 million school children all over the country.

While watching the science lesson from theTiangong-1 on the morning of June 20, 2013, Wang Lutian, a 10-year-old disabled student at a special school in downtown Beijing, was drawing a colorful rocket with crayons in his classroom. “Moon...stars...a rocket to the sky,” Wang explained his work in a cheerful voice. At that time, he and more than 100 other disabled students were enjoying the lesson given by Wang Yaping, who talked about movements in micro-gravity（微重力）environments. “Zerogravity!” Qian Shaohong, another student at the school, shouted when he saw astronaut Nie Haisheng making a show of crossing his legs in mid-air. “Scientific knowledge has helped open a window for the children to know about the world,” said Zhang Yini, a teacher at the school.

The lesson also increased interest in space science among teenagers living on the “roof（屋脊）of the world”. “I was most interested in the presentation of the ‘water ball’ in a gravity-free environment. It’s really amazing,” said Rigzin Jigme Doje, a high school student in Lhasa, Tibet. Describing himself as a lover of physics, Doje said the lesson helped him stay true to his dream of becoming a physicist.

The lesson also encouraged other Tibetan school children to relate the mysterious world of outer space to their hometown.

As we all know, too much rubbish is a big problem for our environment. A woman in Indonesia’s Java island has     61     a great idea—lending books to children in exchange for rubbish.

Raden Roro Hendarti     62     a “trash library”, hoping to make children read more as well as make them realize the importance of environmental protection. Each weekday, Raden puts all kinds of books on the back of her three-wheeler（三轮车）and rides to Muntang village. There, children queue to exchange plastic cups, bags and other rubbish for books from Raden’s mobile library. In the library where Raden works, there are     63    books. Every time she shows up, children run to her “trash library”. They all carry trash bags, and Raden’s three-wheeler is quickly     64     rubbish. It is then sorted out and sent for recycling or sale. She says, “We all should take care of our trash in order to fight climate change and     65     the earth.”

Growth, in some ways, is a process in which we know ourselves better. Do you know yourself? Maybe your handwriting shows who you are.

Have you ever compared your handwriting with your friends’ to see how different it is? Like fingerprints, no two people share the same handwriting. Your handwriting can actually say a lot about what kind of person you are. Try writing out a sentence: The quick brown fox jumps over the lazy dog. Then see what your handwriting says about you.

Size of your handwriting

Did you know that the size of your handwriting can represent the level of your self-respect and self-awareness (自我意识)? Large handwriting may show that you’re easy to get along with and you want to be noticed by others. On the other hand, small handwriting may mean that you’re shy and careful, and always pay attention to-details. Medium-sized handwriting shows that it is not hard for you to get used to a new environment.

Spacing between words

Do you leave a large space between your words when you write? According to a study, the distance between two words can show how close or how far you feel towards others. If you write with wide spacing between your words, it may mean that you enjoy your freedom. On the other hand, people leaving narrow spacing between words may like staying with others.

Slant (倾斜) of the words

Did you know that the slant in your handwriting can tell how you treat people and things around you? Slanting to the right means you welcome or accept new ideas easily. And you think of your friends and family are more important than anything else. While slanting to the left may show that you think deeply about your own thoughts, feelings or behaviors. And you are likely to work behind the scenes better. If you write without slanting at all, you may be practical.

Although the handwriting analyses (分析) are not always true, we can read them for fun. What matters most is you should write carefully.

Every student has a hero who has a great influence on his or her life. Have a guess who my hero is? Hou Yifan. Read the article and find out who she is!

In 2020, people around the world were impressed by the chess prodigy (天才) Beth Harmon in The Queen’s Gambit (《后翼弃兵》). However, there’s a s    76     “queen of chess” in real life—28-year-old Hou Yifan.

Hou started playing chess at 5 years old in 1999. At that time, her parents took Hou to try different brain games at a training center. “With the interesting shapes, I was attracted by the c    77     and decided to take it up,” said Hou.

After playing for two years as a hobby, Hou met her c    78    —grandmaster Tong Yuanming—and took up professional training.

“Chess is a mind game full of u    79     possibilities. Even when there are only five or six pieces l    80     on the board, you have to think it over and cannot calculate (计算) all the variations,” said Hou. “So instead of too much focus on theories, we should rely more on practice and strategy (策略).”

Learning strategies from previous competitions and practising chess quickly became her daily life. Luckily, her e    81     were soon rewarded. At 13, she became China’s youngest ever National Women’s Champion and then became the youngest chess champion in the world at 16.

A    82     the famous chess star was known all over the world, Hou always stayed modest. “I’m happy to win these titles, but I know this is a coin w    83     two sides,” Hou added. “As you attract public a    84    , your faults are amplified (放大). So I should shrug (抛开) the honors off and stay motivated to keep improving.”

“I have to know more,” she said. “I have to open my eyes to see the whole world.” Now, the 28-year-old has become a teacher at Shenzhen University. She wants to “bring the method she learned in China and the West together and a    85     international chess to reach more young Chinese people”.
