Life today is much{#blank#}1{#/blank#} . However, there are new problems. One of the biggest ones is pollution. Water {#blank#}2{#/blank#} has made rivers dirty. It kills fish and {#blank#}3{#/blank#}  our drinking water. Noise pollution makes us speak {#blank#}4{#/blank#}  and become angry more {#blank#}5{#/blank#} . Air pollution is the {#blank#}6{#/blank#} serious kind of pollution. It's bad for all {#blank#}7{#/blank#}  things in the world.

    It's not necessary to be the same. My best friend Larry is quite different from me .He is {#blank#}1{#/blank#}and more outgoing than me .He always makes me {#blank#}2{#/blank#}We both like sports ,but he plays tennis better, so he always wins. However, Larry often helps to {#blank#}3{#/blank#}（bring）out the best in me. Larry is much less hard-working .I always get better grades than he does, so maybe I should help him more. And then we both enjoy {#blank#}4{#/blank#} together. I'm shy so it's not easy for me to make friends. My favorite {#blank#}5{#/blank#} is "A true friend reaches for your hand and touches for your heart."
