Lots of us have dreams of doing big business when we grow up. However, Moziah Bridges, {#blank#}1{#/blank#} 14-year-old boy in the US, is now the CEO of his own company. He {#blank#}2{#/blank#} (sell) $ 200,000 bow ties(领结) since 2011.

    One day about four years ago, when Moziah {#blank#}3{#/blank#}(shop) for bow ties, he found they were only in "ugly" black and red. He wanted a change. So he asked his grandma {#blank#}4{#/blank#} (teach) him how to sew (缝), and finally developed the talent of creating bow ties. However, his first bow tie {#blank#}5{#/blank#}(look) nice. The boy never gave up and kept on {#blank#}6{#/blank#}(practice). He used colourful cloth with different pictures. His parents {#blank#}7{#/blank#}friends started to like his bow ties. Then he tried to sell them online to several stores {#blank#}8{#/blank#}the south. Moziah's bow ties soon {#blank#}9{#/blank#}(become) popular. Now his business has increased quickly. Moziah's mother said, "You don't have to wait until you're older. If you have a dream, just go {#blank#}10{#/blank#} it."

    The Earth is a planet. It and seven other planets go {#blank#}1{#/blank#} the Sun. We {#blank#}2{#/blank#} (call)the eight planets and the Sun the solar system. {#blank#}3{#/blank#} first planet, next to the Sun, is Mercury(水星). It is 58 million {#blank#}4{#/blank#} (kilometer)from the Sun. Venus(金星)is the second planet from the Sun, and {#blank#}5{#/blank#} (we)planet, the Earth, is the third. It is 150 million kilometers from the Sun.

    Jupiter(木星), Saturn(土星), Neptune(海王星)and Uranus(天王星)are all {#blank#}6{#/blank#} (big)than the Earth,  {#blank#}7{#/blank#} Venus, Mars and Mercury are smaller than the Earth.

    Animals, trees and humans can only live {#blank#}8{#/blank#} the Earth-the other planets in our solar system do not have air {#blank#}9{#/blank#} water. Do any planets in other solar systems have {#blank#}10{#/blank#} (life)? We don't know about it.
