Answer 1

分析 將2月2日寫(xiě)入你的日記！它是世界濕地日！它是1971年簽署"濕地公約"的日期的標(biāo)志．這個(gè)特別的日子從1997年首次慶祝，以后每年都慶祝．
   慶�；顒�(dòng)是一個(gè)行動(dòng)呼吁．它是一種向人們展示濕地對(duì)人們有多重要和有用的方式．在世界濕地日，世界各地的人們參加許多濕地活動(dòng)．人們參觀當(dāng)?shù)貪竦兀�有一些關(guān)于濕地的重要的演講．人們聚在一起清理他們當(dāng)?shù)氐臐竦�，兒童�?huà)一些圖片來(lái)宣傳這一天．人們還進(jìn)行船賽．
   世界濕地日是很重要的！如果沒(méi)有濕地，未來(lái)任何人都不會(huì)有水喝．濕地幫助保護(hù)自然和資源，比如淡水．在世界上已經(jīng)有超過(guò)1億人沒(méi)有淡水．
   許多人不知道濕地是多么重要．他們可以理解為什么大象或老虎是重要的，因?yàn)樗麄兪呛艽�，很美麗的�?dòng)物．他們很難了解濕地中的動(dòng)物是多么重要．這些小動(dòng)物，如青蛙和蝸牛，在保持自然的平衡發(fā)揮非常重要的作用．
   所有的植物和動(dòng)物是食物鏈的一部分．如果小的濕地動(dòng)物死亡，食物鏈中的一些動(dòng)物將沒(méi)有什么可吃了．它們也將會(huì)死亡．在世界，人們需要濕地來(lái)保持自然的平衡．如果我們今天不保護(hù)自然，明天它就會(huì)消失．

解答 46．B．細(xì)節(jié)理解題．根據(jù)第一段中的"Put 2 February in your diary!It is World Wetlands Day!"可知．應(yīng)該是將"2月2日"寫(xiě)進(jìn)日記中．所以本題選B． 
47．A．細(xì)節(jié)理解題．根據(jù)第二段中的"On World Wetlands Day，people around the world takepart in many wetlands activities．"可知全世界的人們都在慶祝這個(gè)節(jié)日，所以本題選A． 
48．D．推理判斷題．根據(jù)第二段中的"On World Wetlands Day，people around the world take part in many wetlands activities．People take trips to the local wetlands．There are talks about how important the wetlands are．"可知A、B、C三個(gè)選項(xiàng)是正確的，而D選項(xiàng)中說(shuō)人們通過(guò)談?wù)撎鞖鈦?lái)慶祝世界濕地日，在文中并沒(méi)有涉及．所以本題選D． 
49．A．細(xì)節(jié)理解題．根據(jù)第四段中的最后一句話"These small animals，such as frogs and snails，play a very important part in keeping the balance of nature．"可知，小動(dòng)物在維持自然界平衡中起著重要的作用，所以本題選A． 
50．A．主旨大意題．通讀全文可知，本文主要通過(guò)世界濕地日向我們說(shuō)明了濕地在人們生活中的重要作用，所以本題選A．

點(diǎn)評(píng) 本文主要向我們介紹了世界濕地日的有關(guān)信息，向我們展示了人們?cè)谑澜鐫竦厝账�做的宣傳和活�?dòng)，以此來(lái)告訴人們濕地在人們生活中的作用．在題目中細(xì)節(jié)題比較多，在做題時(shí)需要將題目中的關(guān)鍵信息與根據(jù)短文中的信息相對(duì)照，從而得出正確的答案．
