For many people, life is a lot {#blank#}1{#/blank#} (easy) today. Medicine and diet are improving, and people are getting {#blank#}2{#/blank#} (healthy) and living {#blank#}3{#/blank#}(long). But communication is changing {#blank#}4{#/blank#} (fast) of all. Today, with the Internet, people can communicate {#blank#}5{#/blank#}(easily) than ever before with friends all over the world.

    Not all the changes are {#blank#}6{#/blank#}(good) ones. More people drive cars instead of riding bikes, so they are not as {#blank#}7{#/blank#}(fit) as they were. Increasing traffic makes the roads {#blank#}8{#/blank#}(crowded) than ever, and it also makes pollution {#blank#}9{#/blank#}(bad). We must all work harder to reduce pollution.
