—Yes. Not only I but also my mother __________ it.

    American Thomas Edison (1847-1931) was one of the greatest {#blank#}1{#/blank#} (inventor) in the world He made over 2,000 {#blank#}2{#/blank#} (invention)in his life. The most famous one was the light bulb!

    Thomas Edison spent a long time {#blank#}3{#/blank#}(make) the light bulb. He tried over 1,600 different kinds of materials to get the right filament(灯丝)for the light bulb. He used things like the hair from a man's beard! Some people {#blank#}4{#/blank#} (not think) he could make it finally he did.

    {#blank#}5{#/blank#} Edison went to school for only three months. His teacher told him that he was so stupid that he couldn't learn {#blank#}6{#/blank#} (something). But he kept {#blank#}7{#/blank#} (study) with his mother's help. He learned everything he needed {#blank#}8{#/blank#} (know).

    When Edison worked on {#blank#}9{#/blank#} new kind of battery(电池), he tried out 8,000 ways to make it. Then he said, "Well, at least we have found 8,000 things that don't work!

    This is the longest lasting light bulb {#blank#}10{#/blank#} the world. The light burns for 108 years in California(加利福尼亚), the USA. The light is still working today.

    In 1990, when I {#blank#}1{#/blank#} (be) nine years old, I wanted very much to find {#blank#}2{#/blank#} penfriend. I found Ashley's address in a magazine, and decided {#blank#}3{#/blank#} (write) to her.

    I sent off my letter with a little hope. Very quickly, I received her letter.{#blank#}4{#/blank#} my surprises Ashley was only one month {#blank#}5{#/blank#} (old) than me. I learned some new expressions from her. I {#blank#}6{#/blank#} (real) liked this new friend

    Letter after letter, year after year, Ashley and I continued to write to one another. A letter would be received and I'd write back right away. We would send each other birthday and Christmas {#blank#}7{#/blank#} (gift).

    Eight years later, my parents decided it was time {#blank#}8{#/blank#} me to meet this friend. They drove me down to Mississippi for a few days. We {#blank#}9{#/blank#} (have) a good time together. We did the things that teenage girls loved to do.

    Twenty—five years after the {#blank#}10{#/blank#} (one) letter, Ashley and I still have an amazing friendship. Although we don't write letters now, we communicate through mobile phones and the Internet.
