As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that radiation (辐射) is the greatest danger to spacemen 'in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage (危害) done by radiation won't be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really helpful medicine has been found so far.
Space rubbish is also thought a great danger to spacemen. It's reported that there are 9, 000 man-made things flying in space. About 300% of these are satellites (卫星) , 10% are spaceships, and the rest are space rubbish. An explosion (爆炸) in 1996 made a cloud of 300, 000 fragments (碎片), each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should care for space and do something to help improve the space environmentshows the man-made things in space in the correct way.

Have you ever wished to have an umbrella that makes your hands free? Alan Kaufman has come up with the “Nubrella”, which means “new” + “umbrella”. It is the first truly hands-free umbrella in the world. The inventor says that it stops rain, wind and snow and can keep your head, face and hair dry.
“I never planned to invent a product. I just noticed a problem and had a new idea,” said the inventor. The idea for the invention began on one rainy day. Mr Kaufman was standing in one of his stores. He began to look at people’s umbrellas. He found that they had to try very hard to keep their umbrellas in the right place. At that moment an idea came into his mind. He ran to his desk and drew a picture. In this way, the nubrella was born.
One cool feature of the nubrella is that you don’t hold it like a normal umbrella; you wear it. The shoulder straps (肩带) of the nubrella allow people to be fully hands-free, so when walking in the rain with the nubrella, you are able to use your cell phone or drink a hot cup of coffee. Also, the nubrella will never be inverted (颠倒) in the wind. The new umbrella is far safer than traditional ones, because it has no sharp points.
“Nubrella” is a kind of _____ umbrella.
| A．normal | B．hands-free |
| C．traditional | D．paper |

Which of the following is not right?
| A．"Nubrella" means "new" + "umbrella"． |
| B．The idea of the nubrella came from the rainy day． |
| C．Walking in the rain, you'd better take the nubrella． |

For many years, a small percentage of homeowners have fixed solar panels (太阳能板) on their rooftops. Those panels collect some of the sun’s energy and either change it into electricity or use it to heat water. Until recently, the panels were too expensive for average homeowners, and their designs were not attractive. Thanks to new advances, however, solar panels for homes are becoming cheaper and less large and heavy. Now more homeowners are considering using them.
Stores begin to sell Solar panels
Last fall furniture retailer(零售商) IKEA began selling solar panels in its U.K. stores. IKEA has brought the DIY solar choice to the public. While shopping for furniture, shoppers could not add a box or two of solar panels to their shopping cart (购物车). IKEA is partnering with a company. The company deals with fixing and servcing of the solar panels on the roofs. So it is easy for customers to change from old energy system to solar system. If all goes well, IKEA plans to begin selling the panels in other countries soon.
Stylish solar panels
SolTech, a Swedish company, offers a really great solar-power solution. Instead of flat panels, SolTech covers the panels with a special glass tile. And the shape of the glass tile fits traditional tiled roof designs. SolTech recently offers solar systems that heat the home’s air or water. And it also offers one solar system that produces electricity.
______________
New technology has turned windows into solar panels. SolarWindow technology enables see-through windows to produce electricity after the glass surface is added with a special coating. Amazingly, SolarWindow can produce electricity in low-light conditons and can even turn indoor, man-made light into electricity! Since buildings are getting taller and about 60 percent of an office building’s surface is covered with windows, solar window could become a very popular way for people to produce energy and save money.

Learning a new language
A new language learner usually uses different learning methods. Learning a language sharpens your brain and helps you prevent memory problems in later years.
Master a new subject
Each week, choose an animal, a bird or a fish, and read everything you can about it. Go on learning unitl you become an expert on the subject.
Use your non-dominant hand
If you are right-handed,use your left hand for everyday activities, or use your right hand if you are left-handed. Doing familiar things in a new way will cause your brain to create new neural networks.
Read often
As you read, take the time to look up people or places that aren’t familiar. Reading can enlarge your vocabulary if you search for words and expressions that you don’t know.
