三、专题巧练
(一)
When I was nine years old, I wanted to keep a pet fish. After months of ,
I finally had enough money to get one. I named it Bob. I put beautiful toy
house with windows in the tank so that Bob could swim through. Sometimes,
I would draw pictures of fish and sea plants and tape them to the side of the
tank, so Bob wouldn't get lonely while I at school.
However, a month, I noticed that the tank was getting dirty. My dad
asked me it into the kitchen. He wanted to make sure I knew to do so
that Bob wouldn't get hurt.
First, my dad told me to reach into the tank and take the house away.
I took my hand out of the water, I noticed that the water was a lot than
I thought.
"That's smelly!" I said. "Let's hurry up and the fish out of the
water, Dad!"
"Not so fast, Ben," Dad said. "We need to save some of the old water,
Bob needs a place to stay while we clean the tank."
"Why?" I asked.
"Running water from the tap can be harmful to fish," Dad explained. "That
we can't put Bob into fresh water right away. Instead, we need to put him in
a cup with of the dirty water for a while."...
All seemed so easy. I hoped the next time I would be able to clean the tank all
by .
