The book The Crying Sea is for children. It is written by Simon Walker. It's {#blank#}1{#/blank#}  the sea. It tells us about different {#blank#}2{#/blank#}  of water pollution and the things we can do to keep the sea {#blank#}3{#/blank#} . It also tells us the different ways we can {#blank#}4{#/blank#}  the seas. In this book, Simon Walker said: “Three quarters of the earth is water. {#blank#}5{#/blank#}  thousands of years, the seas have helped {#blank#}6{#/blank#}  by giving us food and water. Now, we are feeding them dirty water from factories and rubbish from our homes. The seas are {#blank#}7{#/blank#}  because they are very sick. Please help to save them.”
    You can {#blank#}8{#/blank#}  many wonder photos of the sea in this book. There are also beautiful photos of sea {#blank#}9{#/blank#}  like whales, and seahorse. You can see pictures of some famous dolphins. I think this is a very {#blank#}10{#/blank#} and useful bool.

It should be good enough to be used by many different computers. If{#blank#}4{#/blank#}the network was not working, information could be sent through another part, In this way the computer network system would keep on working all the time.
