【答案解析】美国人几乎没有一个一辈子不挪动地方；他们由小镇搬到城市，又搬到郊区，从中学到另一个州的大学，由一个地区的某个工作岗位换到别的地方的更好的职位，从把孩子养大的家搬到打算退休以后安度晚年的家。每搬一次家，他们都不断地结交新朋友，这些已成为他们新生活的一部分。 [解析]
Few Americans stay put for a lifetime. They move from town to city to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where they raise their children to the home where they plan to live in retirement. With each move they are forever making new friends, who become part of their new life at that time.

【答案解析】体育赛事充满精彩时刻，但也许没有什么能比得土跑完马拉松的那一刻，那是所有赛事中最长、最艰苦的。“马拉松”一词来自希腊的一个村庄，公元前490年在那里发生一次著名的战争。希腊人战胜了波斯人，一个士兵一直从马拉松跑到了雅典 (大概有40多公里)去传递这个好消息。在1896年现代奥林匹克运动会开始时，主办者得知此事，从此便开始有了马拉松比赛。 [解析]
Sport is full of wonderful moments, but perhaps nothing is as exciting as the finish of the marathon. It is the longest, hardest race of all. The name "marathon" comes from a village in Greece. A famous baffle was fought there in the year 490B.C, When Greek had beaten the Persian, a soldier ran all the way from Marathon to Athens—more than 40 Kilometers—to tell people the good news. When the modem Olympic Games were started in 1896, the organizers knew this story. The Marathon has been a race since then.
