根据短文内容,选择最恰当的答案。
Elena jogged with her dad in some empty lots (空地) at the edge of town. These out-of-the-way lots
were good places to jog. But the lots were full of rocks and rubbish.
One day, Elena saw a sign on the lots. It said, "New City Park." Elena was excited. Maybe the park
would have a jogging trail (小道)!
Elena told her parents about the sign.
'I read about the park in the newspaper," said Elena's father. "The city wants volunteers to help clean
the area. Then the city will build a soccer field and a playground."
"Will they build a jogging trail?" Elena asked.
"No. the paper didn't mention a jogging trail."
"Well, perhaps if I help clean up the lots, they'll put in a jogging trail, "said Elena.
On Saturday Elena went to the lots. Many adults were working there. Some were picking up
rubbish. Some were moving rocks.
"I want to volunteer," Elena told a man. "What can I do? ",
"This is not a job for children," said the man. "You'd better go home. "
Elena looked around. She could carry rubbish. She could move rocks. A lady was pulling a bag of
rubbish. Elena saw a box of rubbish bags. She took an empty bag.
"I'll take this bag to the Dumpster." said Elena. "Here's a new bag."
"Thanks, "said the lady. "Keep those new bags coming. "
Elena dragged rubbish bags. She told everyone she was glad to help build the park. She explained that
she hoped the park would have a jogging trail.
Elena went to the area every week. Soon everyone knew her and she told everyone how wonderful a
jogging trail would be.
Soon the volunteers cleared the lots. The city could start building. The mayor (市长) gave a speech. He
showed a drawing of the new park. He told them about the soccer field and the baseball diamond. There
would be picnic tables. There would be a playground. The park would even have basketball courts.
There was no sign of a jogging trail.
The mayor thanked the volunteers. Then he asked if they had any suggestions. The volunteers said they
wanted to build a jogging trail around the park.
They told the mayor how helpful Elena had been and how she wanted a jogging trail. The mayor said,
"A jogging trail won't be hard to build. Let's do it!"
Everyone clapped and cheered. Elena cheered loudest of all.
