Are you a big fan of E. T. (Extraterrestrial) or aliens? Then you should read Extraterrestrial Civilizations (《地球以外的文明世界》) by American writer Isaac Asimov (1920~1992). In his 1979 book, Asimov looked at whether there is life beyond the Earth. He also talked about how we might be able to communicate with aliens someday. Asimov even told us that there are possibly about 500, 000 civilizations (文明) in the galaxy(银河系). The book may be a little out of fashion since it came out in the 1970s. But you'll still enjoy the good reasoning (推理 ) and imagination of it. Asimov was a science fiction(科幻故事) master. His most famous works talk about the relationship between robots and humankind.

    Humans are going to the Moon for the first time since the last Apollo Mission( 飞行任务) in 1972, 45 years ago.

    SpaceX, a US space technology company, will send two people on a private trip around the moon. And they plan to make it happen in 2018, reported CBS News.

    The company didn't name the two people, how much they were paying or even their gender(性别). But they did say that the mission would use SpaceX's Falcon Heavy rocket and Dragon 2 spacecraft. Both of them are still in development(研发).

    The founder of the company Elon Musk mentioned that the trip would last about a week. "The plan is crazy." Mark Shelhamer, a former scientist from NASA said. "It's impossible to complete the mission. Getting to the moon is a lot more difficult than getting to the International Space Station." However, Musk believes that the trip will be a great success. The spacecraft will run on autopilot(自动驾驶) and the two space tourists will get hard training.

    "There is some risk there," Musk said. "But we'll do everything we can to minimize(将…减到最少) that risk."

    If you have your own Acme Rocket Launcher, you can create and send up rockets that show off your personality and creativity.

    All you need is your Acme Rocket Launcher and a few simple household materials:

    ★a 500ml plastic cola bottle     ★scissors     ★colored markers

    ★poster board     ★glue

What to do:

Step 1     Clean the cola bottle completely and allow it to dry.

Step 2     Use markers to draw three small triangles (三角形) and one large triangle on the poster board. Cut out the triangles.

Step 3     Roll (卷起) the large triangle so that two of its sides touch and it forms a rocket's nose cone. Glue the sides of the cone so that it holds its shape.

Step 4     Glue the nose cone to the bottom of the bottle to make the top of the rocket.

Step 5     Glue the smaller triangles to the other end of the cola bottle, around its opening. The triangles will be the tail fins.

    Follow the launching instructions included with your Acme Rocket Launcher and have a blast!

    Around the world, there are about 7,000 National Parks. Most of them cover huge areas of land where nobody lives. However, the National Parks in England include places where people live and work, as well as wild areas where there are few human activities.

    The National Parks in England are called "England's Breathing Spaces" because they are places where people can go to be in the open air, away from the dirt and noise of cities. They provide wonderful scenes of mountains, woods, grasslands and wetlands. And there are plenty of activities to do in all of the National Parks in England. Visitors can walk or ride bikes for fun. Many of the parks put on activities for families.

    Every year there are about 110 million visitors to the parks, bringing many benefits(益处) to the areas. At the same time, it creates problems, too.

    First, life can be difficult for local people. Car parks and roads are too crowded. Gift shops and cafes take the place of many everyday shops. Even house prices in some areas can become too high. Besides, country roads can be damaged, for too many people walk, cycle or ride horses on them. Roads can be rebuilt, but then they look less natural. Another big problem to the National Parks is litter. In the parks it is a danger to wild animals. Broken glass can also cause fires by focusing the rays of the sun. Such fires in wild places can be out of control.

    _______All National Parks in England are making more rules, which tell people how to take good care of their environment. If these rules are followed, the National Parks will be well kept and continue to give pleasure to many people for a very long time.

Close your eyes and think back to the last time'you picked up a book, a magazine or a newspaper. While it may be easy for some to think of these moments, others may find it difficult. 

I always enjoy reading the newspaper. Even was a child, I would search for the stories in Kids Post. It is hard for me to watch print journalism（新闻业） disappear as most people get news through digital platforms. 

Since the introduction of the internet, society has found other ways to spread news and information. The internet is everywhere. This helps people get news much easier, because it is at one's fingertips at all times. The spreading of news began to change. Anyone can post online easily. Digital media may make news more available to read, but it raises questions about the most important rule of journalism: accuracy（准确性）. 

Readers may hate the spread of unreal information. The attitude is good for print journalism. Every day, as the public opens their favorite books or newspapers, it is important to think about how much effort goes into creating that body of work. Behind the scenes of every publication is a team of journalists working tirelessly to keep the public informed of the events which took place recently. 

While print journalism is now facing challenges, its future is up to the public. As long as readers continue to value accuracy and journalists stick to this rule, print journalism does not have to disappear. The next time you find yourself aimlessly（漫无目的地） looking through the website, consider buying a book, a magazine, or a newspaper-the future of print journalism will thank you.
