More and more teenagers have problems in their lives. Especially when children are at home alone, they often feel {#blank#}1{#/blank#}(孤单的).

    At this time, children can try to travel around the world, enjoy the  {#blank#}2{#/blank#}(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 {#blank#}3{#/blank#}(实验). If you want to {#blank#}4{#/blank#}(装满) a bag with sand, you have to {#blank#}5{#/blank#}(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  {#blank#}6{#/blank#}(历险)of Tom Sawyer which is {#blank#}7{#/blank#}(写) by Mark Twain? You can write a book {#blank#}8{#/blank#}(评论) and discuss with your friends.

    All these activities will make a lot {#blank#}9{#/blank#}(意义) to us. Remember: Life is full of fun.

    {#blank#}10{#/blank#}(无论什么) you do, make sure it is colorful and enjoyable.
