9 . The first time my parents watched me compete in a mountain bike race, they tried to get me to quit. While I was riding down a hill, I hit a huge rock, flew through the air and crashed to the ground. However, this kind of thing happens all the time. I just got up as fast as I could, got back on my bike and kept going. And I won that race, despite taking quite a spill!

My earliest bike memories are of my father taking me out for rides in the child seat on the back of his ten-speed. A couple years later, I got my first bike. But my parents wouldn’t let me ride more than a few blocks from the house until I was ten. The morning of my tenth birthday, I got my older sister to take me on a long ride. We ended up at my aunt’s house. I was totally exhausted and every muscle in my body ached. But I didn’t care. I knew that this was only the beginning, and all I could think about was where my next trip would take me.

When I was in the eighth grade, our gym teacher, Mr. Raines, sent out a flyer about starting a mountain bike club. I ran to his office between classes and signed up. Over the next few months, the ten of us who joined the club worked on our biking skills. Besides taking us out riding, Mr. Raines taught us about bike safety, and showed us how to properly maintain and repair our bikes. He also helped us form a mountain bike team. At first, we competed against each other. Later, we went up against other schools. We continued to train and compete all through high school.

Biking has been the major focus of my life. Those early trips on the back of my father’s bike got me started. The long rides with my sister increased my enthusiasm. Then, the training and competitions in the bike club guaranteed that I would turn into a lifelong bike fan. I think everyone should have a hobby like this－something that is good for them and makes them happy.

10 . Train Floating On Air

A train that floats on air? It's not magic—it's magnets (磁). And it's close to reality. In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus. In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power. And in China, a magnet train line linked Shanghai with nearby Pudong Airport.

These trains use magnetic levitation (悬浮) technology, “maglev” for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles repel each other.

How does it work?

Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past.

When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down.

Maglev doesn't rely on the friction (摩擦力) of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop.

1. This passage is about ________.

A．maglev

B．magnets

C．levitation

D．electricity

2. Which of the following is a repelling action?

A． 

B． 

C． 

D． 

3. What can we learn from the text?

A．A magnet filled guiding way is formed inside a maglev train.

B．Instead of electricity magnets are used as the power of n maglev.

C．Maglev trains can climb hills with the help of magnet wheels.

D．Electric currents decide the movements of a maglev train.

4. What is the difference between a maglev train and an ordinary train?

A．A maglev train can climb mountains without power while an ordinary one can't.

B．A maglev train can travel in college campus while an ordinary train is not allowed.

C．Travelling without a track, a maglev train is safer and smoother than an ordinary one.

D．Floating on a track, a maglev train is faster, quieter than an ordinary railway train.
