More and more teenagers have problems in their lives. Especially when children are at home alone, they often feel (孤单的).

    At this time, children can try to travel around the world, enjoy the  (自然的) and man-made wonders of the world. Sometimes we may happen to attend the public holidays in foreign countries.

    Do you like visiting museum? I advise you to go to the Science Museum in London. The most interesting room is the Launchpad on the third floor, because there are lots of physics (实验). If you want to (装满) a bag with sand, you have to (控制) a kind of truck on wheels and move it into correct places.

    Besides, read great books if you don't want to go travelling. Have you read The  (历险)of Tom Sawyer which is (写) by Mark Twain? You can write a book (评论) and discuss with your friends.

    All these activities will make a lot (意义) to us. Remember: Life is full of fun.

    (无论什么) you do, make sure it is colorful and enjoyable.
