Answer 1

分析 将2月2日写入你的日记！它是世界湿地日！它是1971年签署"湿地公约"的日期的标志．这个特别的日子从1997年首次庆祝，以后每年都庆祝．
   庆祝活动是一个行动呼吁．它是一种向人们展示湿地对人们有多重要和有用的方式．在世界湿地日，世界各地的人们参加许多湿地活动．人们参观当地湿地．有一些关于湿地的重要的演讲．人们聚在一起清理他们当地的湿地，儿童画一些图片来宣传这一天．人们还进行船赛．
   世界湿地日是很重要的！如果没有湿地，未来任何人都不会有水喝．湿地帮助保护自然和资源，比如淡水．在世界上已经有超过1亿人没有淡水．
   许多人不知道湿地是多么重要．他们可以理解为什么大象或老虎是重要的，因为他们是很大，很美丽的动物．他们很难了解湿地中的动物是多么重要．这些小动物，如青蛙和蜗牛，在保持自然的平衡发挥非常重要的作用．
   所有的植物和动物是食物链的一部分．如果小的湿地动物死亡，食物链中的一些动物将没有什么可吃了．它们也将会死亡．在世界，人们需要湿地来保持自然的平衡．如果我们今天不保护自然，明天它就会消失．

解答 46．B．细节理解题．根据第一段中的"Put 2 February in your diary!It is World Wetlands Day!"可知．应该是将"2月2日"写进日记中．所以本题选B．

49．A．细节理解题．根据第四段中的最后一句话"These small animals，such as frogs and snails，play a very important part in keeping the balance of nature．"可知，小动物在维持自然界平衡中起着重要的作用，所以本题选A． 
50．A．主旨大意题．通读全文可知，本文主要通过世界湿地日向我们说明了湿地在人们生活中的重要作用，所以本题选A．

点评 本文主要向我们介绍了世界湿地日的有关信息，向我们展示了人们在世界湿地日所做的宣传和活动，以此来告诉人们湿地在人们生活中的作用．在题目中细节题比较多，在做题时需要将题目中的关键信息与根据短文中的信息相对照，从而得出正确的答案．
