The Wilsons decided to go overseas for vacation. They had a family
meeting to plan the vacation. "First," Mr. Wilson said, "we should decide
where we are going."
     "I don't agree," Mrs. Wilson said, "I think we should decide when we are
going first. We don't want to go to places when they are cold."
     Mr. Wilson agreed, so the family's first decision was when to go on
vacation. They decided to go in July. "Now we can decide where to go," said Mr. Wilson. "But, Dad," Ben said, "don't you think that where we go depends on(依赖,取决于)how we go? If we plan to fly, we can go a long way. If we
plan to drive, we can't go far."
     Again, Mr. Wilson agreed, and they discussed this. At last they agreed to
travel by plane. And so the planning meeting went on. The next day, one of
Mr. Wilson's friends at work asked, "Where are you going for vacation?"
     "Well," Mr. Wilson told him, "we are going in summer by plane, but I
don't know where we are going!
