All too often, a choice that seems sustainable(可持续的)turns out on closer examination to be problematic. Probably the best example is the rush to produce ethanol(乙醇) for fuel from corn. Corn is a renewable resource —you can harvest it and grow more, almost limitlessly. So replacing gas with corn ethanol seems like a great idea. 

    One might get a bit more energy out of the ethanol than that used to make it, which could still make ethanol more sustainable than gas generally, but that's not the end of the problem. Using corn to make ethanol means less corn is left to feed animals and people, which drives up the cost of food. That result leads to turning the fallow land –including, in some cases, rain forest in places such as Brazil—into farmland, which in turn gives off lots of carbon dioxide (CO) into the air. Finally, over many years, the energy benefit from burning ethanol would make up for the forest loss. But by then, climate change would have progressed so far that it might not help.

    You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental(环境的) costs. Even then, technology and public keep developing, and that development can lead to unforeseen and undesired results. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.

    A spaceship is flying to the sun in summer 2018! It will be the first-ever to a star and will be one of the biggest achievements space exploration (探险) in human history. The purpose is to study the sun's outer atmosphere and better understand how stars work.

The spaceship, with no man inside, will fly within 4 million miles of the sun's surface - right into the solar atmosphere, where the temperature is over 4,500℃. To protect the spaceship, it is covered with a 12cm-thick coating.

    The spaceship is called Parker Solar Probe and it is named after Eugene Parker, a professor from the University of Chicago. It's the first NASA spaceship to be named after a researcher who is still alive. In 1958, Eugene Parker first created the term “solar wind”-the sun sending out a flow of particles (颗粒) and energy.

    “The spaceship is going where it has never been before. It's very exciting that we'll finally get to know more about the solar wind. I'm sure there will be some surprises. There always are,” said Professor Parker.

    Parker calls it a heroic scientific space adventure, and he means that the spaceship will have to experience high temperatures and sun radiation (辐射). “The spaceship is going to do the hottest and fastest work. I love to call it the coolest hottest work under the sun,” said Scientist Fox Nasa.

    Lovell Camps Kids' Club in Switzerland

    Lovell Camps Kids' Club is an English language Montessori（蒙台梭利）style club. Children will enjoy a wonderful and safe learning experience which includes language activities, cooking, arts and crafts, singing, dancing, etc.

    Learning outside the classroom plays a necessary role at Lovell Camps, making children experience the outdoors. During the summer months this can include visits to local playgrounds, farms and indoor or outdoor swimming pools. Winter time gives children the chance to go skiing and play outside in the snow.

    The Lovell Camps Kids' Club is for pre-school children aged between 2 and 5.

    What's included:

    Fees include: Healthy snacks and school equipment. If you choose the skiing activity, fees include transportation to and from the ski hill and professional ski instructions.

    Throughout history, music spread among people of different cultures. In today's technological advanced society, however, people spread music online, sometimes without an artist's permission. This can lead to many problems, and music companies are now cracking down on this practice. Sharing music online without permission is theft (盗窃).

    Sharing music online prevents recording companies from making money from their efforts. They say that sharing music online has resulted in a huge drop in profits and sales over the past 10 years. People who find music for free online are not paying for CDs or every MP3 downloaded. To truly understand the influence of music piracy (盗版) on creators, one must understand how many people are involved in the recording process. For the sale of each album, profits must be shared between musicians, sound engineers, music producers, managers, advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved.

    There are many people who don't see the harm in sharing music online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he should be able to do with the material whatever he wants. While he may have legally paid for the music, he does not have the right to provide permission, which means people like the blogger are thieves.

    Although we don't spread today's music the same way we did before, there's no doubt that people around the world love to share music. However, internet piracy would prevent musicians from continuing producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profit to continue their music careers.

    The spine (脊柱) stands at the center of your health, providing your body with structure and support. It also contains a major collection of nerves that deliver electric signals from the rest of the body to your brain. So it's important to take care of it.

    Staying in a good position is one of the most important things to keep your spine healthy. A proper position means standing or sitting while keeping your spins straight, except for its natural bending. Positions play a vital part even when you're asleep. Stomach sleeping is far from a good idea. Many people prefer sleeping on their side, which is in the interests of their spine. Sleeping on your back has lots of benefits yet can cause lower back pain and put some pressure on your spine.

    Staying still for too long — even if your position is good — can be hard on your back. Especially if you work at a task most of the day, it's important to get up and stretch (伸展) periodically. Strength exercises with light weights like push-ups can also help by strengthening the muscles. However, don't overdo the exercise, as repeated movements can hurt the muscles around the spine, as trying to lift heavy weights with poor technique.

    Vitamins also affect the health of your spine. In particular, vitamin B and omega-3 fatty acids help keep nerves healthy. Another important part is vitamin D, which is required for strong bones. Vitamin D can come from some foods, but it's also absorbed from sunlight, so it may help to do some exercises outside. At last, many of the actions necessary to keep a spine healthy are similar to those used to protect your health in other ways. So protect your back, and the rest of the body will benefit.
