My parents
told me we were going camping during winter vacation. Camping! They are always
trying to get me outside more. It seems like my mom is always saying, "Brian,
turn off the computer!" or "Brian, put down your phone and talk to
us!" They don't understand that I'm in the zone when I'm using a
keyboard, so of course I don't want to stop.
We drove
for an hour to Everglades National Park. As soon as we got there, I couldn't
get a signal(信号)
for my phone. Suddenly, I was facing three days of no contact with the outside
world. My mom tried to tell me I'd like it, "You'll be able to look around
more when you're not staring at a screen."
We took a
hike with a ranger(护林者) in the afternoon. He explained a lot to us about the Everglades.
At first, I couldn't care less, but after a while I started listening. By the
end of the hike, I realized there was more action going on in the park than in
most video games.
We did a
lot of walking and that night I was really tired. Even so, I woke up in the
midnight, and I was scared at first because of some strange sounds. But then I
realized it was the barred owl that the ranger had described. It sounded like
it was calling out "Who cooks for you? Who cooks for you?" Then I was
not afraid anymore and went back to sleep.
The next
two days we did a lot more exploring. I saw that all the land and water and
animals were connected in the Everglades. Small fish eat mosquito eggs; large
fish eat those smaller fish; and alligators eat the large fish. If you got rid
of(除掉) the
mosquitoes, you might lose some of the other animals higher up the food chain
too.
After we
left, we talked in the car about the Everglades. Right in the middle of our
discussion, I heard a familiar
sound from my phone. My friend Jeff was sending me a message. I reached for my
phone, then put it back down. "Aren't you going to reply?" asked Mom.
"I
will in a little while," I said. My dad and mom looked at each other and
just smiled.
