Trampolining

    What's more fun than standing still? Jumping up and down on a springy piece of fabric (织物)! This activity is known as trampolining and it's sweeping the nation.

    The idea of trampolining is ancient. Eskimos have been throwing each other in the air for thousands of years. Firemen began using a life net to catch people jumping from buildings in 1887. {#blank#}1{#/blank#}

    A gymnast named George Nissan and his coach Larry Griswold made the first modern trampoline in 1936. {#blank#}2{#/blank#} They named their equipment after the Spanish word trampolín, which means diving board. The men wanted to share their idea with the whole world. In 1942 they began making trampolines to sell to the public.

    Trampolines may be fun, but they can also be dangerous. {#blank#}3{#/blank#} Clubs and gyms use large safety nets or other equipment to make it safer. Most trampoline injuries happen at home. Since trampolines are more affordable than ever, injuries are even more common.

    These injuries happen for many reasons. People may bounce too high and land out of the trampoline or onto the springs. {#blank#}4{#/blank#} Perhaps the worst injuries happen when untrained people try to do flips (快速翻转). Landing on your neck or head can cause injuries or even kill you.

    {#blank#}5{#/blank#} There are many things that you can do to practice safe trampolining. Trampolines have been around for a while now. They have brought a lot of joy to many people. They can be a good source of exercise and activity. They can help people improve their balance and moves. But they can also be deadly. It is important to follow some professional guidance. Be sure that you are practicing safety while having a good time. Happy bouncing!

    Each year the Pritzker Architecture Prize (普立兹克建筑奖) goes to a star designer with a long list of attractive buildings around the world. This year's winner is a little different.

    Shigeru Ban has designed museums, homes and concert halls. But Ban is best known for a more simple kind of work: the temporary (暂时的) buildings for people who became homeless after disasters.

    Ban may be the only designer in the world who makes buildings out of paper — cardboard paper tubes (管). Ban actually tested the strength of cardboard tubes, and said he was surprised by what he had discovered. He has used them to build temporary buildings in Japan, Haiti, China and elsewhere.

    “After a disaster, the building material is going to be more expensive,” Ban explains. “But the paper tube is actually not a building material. It is cheap and plentiful. We can get the material easily anywhere. And unlike costs for traditional building materials, the price of paper tubes doesn't jump after an earthquake or flood. The tubes are also lightweight, so you don't need heavy machines to work with them.”

    Ban started using cardboard paper tubes in the 1980s. At that time he had just graduated from the architecture school, and he was looking for a cheap substitute for wood. So he started reusing the paper cardboard tubes that were left over from rolls of paper in his office.

    Ban was born in Tokyo and studied architecture in the U.S. before moving back to Japan to start his practice. Some of Ban's temporary buildings have become permanent (永久的), like the paper church he built after the 1995 earthquake in Kobe, Japan.

    No Food or Drink: Only bottled water is permitted in the Museum

    Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion on the sidelines of the annual session of the National People's Congress that Wi-Fi should not be provided on high-speed trains, as it might disturb communication signals of trains and would also cost a lot in keeping trains in good condition. He also encouraged passengers to enjoy the views, instead of fixing their eyes on tiny screens of smart phones and laptops. However, on last Tuesday Beijing Youth Daily said it should be market demand that decides whether the Wi-Fi is offered on the trains or not.

    An increasing number of residents, especially young white-collar workers, are addicted to their smart phones rather than face-to-face interactions, thanks to the extensive Wi-Fi coverage across the country. That partly justifies Wang's opposition to the offering of Wi-Fi on high-speed trains, because they are not supposed to be dependent on high-tech devices. It is also evident that passengers on trains without free Wi-Fi will use their smart phones and other mobile devices less. However, whether the trains should provide a free Wi-Fi service fundamentally depends on customer demand.

    In other words, state-owned as it is, the China Railway Crop still has to obey relevant market rules, and provide technologically possible services to passengers if that is what they want. It cannot turn a blind eye to customers' wants "for the sake of their well-being".

    Free Wi-Fi, in fact, is already available on a lot of buses and coaches. This is a natural response to their competition with trains (especially high-speed ones), which are significantly faster and safer. The bus companies have been forced to improve their services to survive. It requires proper guidance, not a total ban on the bus, to make up for the negative effects of high-end technologies, such as people's increasing addiction to smart phones.

A huge lake of salty water appears to be buried deep in Mars, scientists reported this week. The presence of water raises the chances of finding life on the red planet. The discovery is based on observations by a European spacecraft. It has excited experts. Water is necessary for life, and scientists have long hoped to prove that it is present on Mars.

Cassie Stuurman is a geophysicist at the University of Texas. In 2016, she found evidence of a huge ice deposit(沉积)on Mars. “If these researchers are right, this is the first time we've found evidence of a large water body on Mars. ”Stuurman said. Researchers are not yet sure how deep the area of water is. So, they cannot say whether it is an underground pool, or just an area of soft and wet soil.

In order to find the water, Italian researchers examined radar signals. The signals were collected over three years by the European Space Agency's Mars Express spacecraft. The results suggest that a 20-kilometer-wide water body lies below ice that is 1.5 kilometers thick. They believe the area is close to the planet's southern pole.

    Mars is very cold, but salt in the water may have kept it from freezing. It is the same as when you put salt on a road to prevent ice from forming. The water would be extremely cold, right at the point where it's about to freeze. And it would be salty. Such conditions are not ideal for life to form. But, she said there are bacteria on the earth that have been able to survive in similar conditions.

Mars has been a popular planet for exploration, with some groups placing instruments on its surface and others examining it from space. In May, NASA launched another spacecraft, the InSight Mars lander which will dig deep into the data under the surface after it reaches a flat area of the planet in November.

Dear Coach,

    I have been out of work for almost six months now and things are starting to get very tough for me. I am practically living out of my savings. I have been looking for a job, but things are really bad and I cannot find a single person who wants to hire me. I know that the main problem is that I do not have a degree. I want to go back to school and get my degree, but I also need a job now. I owe money to some people who have been helping me. Because I am out of work, I cannot pay them back. What do you think I should do? I need to find a job as quickly as possible, and want to know what else to do to get people to give me a chance to work for them.

The Unemployed

Dear Unemployed,

    Before you get yourself in a really bad situation, you need to stop borrowing money from people. If you continue doing that, you will be deep in debts and the situation will get even worse for you. The next thing you need to do is look for a job depending on your abilities, skills, and experience. By doing that, you will be increasing your chances of finding a job that suits you best. And the last thing I will suggest is that you should stop feeling sorry for yourself and continue working hard to get a job that you need. Borrowing money, complaining, and feeling bad for your situation will do no good to you. Stay strong and get out there and start showing the world what you can offer. I promise if you work hard and never give up, you will soon find the job that you are looking for. And while you are doing it, thing about getting your degree as well because it will help you to become more challenging. Try those tips.

The Coach
