阅读下面短文,并按照题目要求用英语回答问题(请注意问题后的词数要求)。

My name is Clara. I still remember that chilly December day, sitting in science class. I had finished a worksheet early and picked up a TIME for Kids magazine. A piece of news caught my eye: NASA (美国宇航局) was holding an essay contest to name its Mars rover (火星探测器). Before I even knew anything else about it, a single word flooded my 11-year-old mind, Curiosity.

I couldn’t wait for the bell to ring so I could get started on my essay. That afternoon, I raced home, sat down at the computer, and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone’s mind…”

Five months later, my mom received a phone call, and immediately, a wide smile spread across her face.

On August 5, 2012, at 10: 31pm, the rover named Curiosity touched down safely on the surface of Mars, and I was honored to have a front-row seat in NASA.

Curiosity is such an important part of who I am. I have always been fascinated by the stars, the planets, the sky and the universe. I remember as a little girl, my grandmother and I would sit together in the backyard for hours. She would tell me stories and point out the stars. Grandma lived in China, thousands of miles away from my home in Kansas, but the stars kept us together even when we were apart. They were always there, yet there was so much I didn’t know about them. That’s what I love so much about space.

People often ask me why we go to faraway places like Mars. My answer is simple because we’re curious. We human beings do not just hole up in one place. We are constantly wondering and trying to find out what’s over the hill and beyond the horizon.
