    Hello. We are students from Thailand, and we want to save the elephants. The elephant is one of Thailand's {#blank#}1{#/blank#}. Our first flag had a white elephant on it. This is symbol of good luck.

    Elephants are {#blank#}2{#/blank#} animals. They can play soccer or music. They can also draw very well. People say that "an elephant never {#blank#}3{#/blank#}." Elephants can walk for a long time and {#blank#}4{#/blank#} get lost. They can also remember places {#blank#}5{#/blank#} food and water. This {#blank#}6{#/blank#} them to live.

{#blank#}7{#/blank#}elephants are in great danger. People cut down many trees {#blank#}8{#/blank#} elephants are losing their homes. People also kill elephants {#blank#}9{#/blank#} their ivory. Today there are only about 3,000 elephants (over 100,000 before). We must save the trees and not buy things {#blank#}10{#/blank#} of ivory. Remember that March 13th is Thai Elephant Day.

    Life in the 2lst century is different from that in the 20th century because many changes have taken place. There are more and more people in the world and most of the lives are longer than before. Computers are much smaller, more {#blank#}1{#/blank#}and more popular. And Computer Science is one of the most important subjects {#blank#}2{#/blank#} . People work fewer hours than they did in the 20th century, and they have more free time for sports, watching TV and travelling. {#blank#}3{#/blank#} is much more convenient and easier. And more people go to {#blank#}4{#/blank#}countries for holidays. There are changes in our food, too. More land is used for building new towns and houses. Then there is less room for cows and sheep, so meat becomes more expensive. People have to eat more vegetables and fruit. {#blank#}5{#/blank#} it's good for people's health.
