“猪——沼气——作物”是常见的生态农业模式，由种植（作物）、养殖（猪）、农户（人）和沼气生产（分解者）四部分组成。有关该生态农业模式的叙述正确的是（    ）

    A man was traveling abroad in a small red car. One day he left the car and went shopping. When he came back, its roof was badly damaged.

    Some boys told him that an elephant had damaged it. The man did not believe them, but they took him to a circus(马戏团) which was near there. The owner of the elephant said, “I am very sorry! My elephant has a big, round, red chair. He thought that your car was his chair, and he sat on it!"

    Then he gave the man a letter, in which he said that he was sorry and that he would pay for all the damage.

    When the man got back to his own country, the customs（海关） officers wouldn't believe his story. They said, “You sold your new car while you were abroad（国外） and bought this old one!"

    It was only when the man showed them the letter from the circus man that believed him.

（甲）富贵不能淫

    居天下之广居，立天下之正位，行天下之大道；得志，与民由之；不得志，独行其道。富贵不能淫，贫贱不能移，威武不能屈，此之谓大丈夫。

（选自《孟子译注》）

（乙）从容就义

    天祥将出狱，即为绝笔自赞^①，系之衣带间。其词曰：“孔曰成仁，孟云取义；惟其义尽，所以仁至。读圣贤书，所学何事！而今而后，庶几^②无愧！”过市，意气扬扬自若，观者如堵^③。临刑，从容谓吏曰：“吾事毕矣。”问市人孰为南北，南面再拜就死。俄有使使止之，至则死矣。见闻者无不流涕。

【注】①自赞：自我总结。②庶几：差不多。③观者如堵：围观人的多得像一道墙。
