15．How did the sea horse get its name？It's not hard to guess．The top half of this fish looks like a small horse．But looking at the sea horse's tail，you might think"sea monkey"is a better name．Then there's the sea horse's pouch （育兒袋）．"Sea kangaroo"might also be a good name for this fish．
Sea horses live in warm ocean waters all over the world．They keep safe from other fish by hiding in plants and grasses that grow under the sea．They can also change colors to match their surroundings．A sea horse remains in one place for hours at a time by winding its tail around a plant．It feeds on live food，such as small shrimp．For a fish that doesn't move around much，the sea horse eats a lot-in just one day，a sea horse can eat 3，000 shrimp!
A sea horse keeps the same mate for its whole life，and it's the male sea horse that gives birth to baby sea horses．How does this happen？Baby sea horses start out as eggs，which come from the female's body．The male carries the eggs in its pouch for about three weeks until they hatch．Soon after the babies are born，the female gives her mate a new set of eggs．
Sadly，the number of sea horses is becoming smaller．Why is this happening？Some places where sea horses once lived have been filled in to make new land．Also，many sea horses are caught and sold as aquarium fish．This really is not a good idea because most sea horses don't live long in aquariums．The best place for a sea horse is the ocean．

分析 本文主要講解了有關海馬的知識，講到了海馬名字的來歷，生活習性，如何繁殖及數量越來越少的原因．
解答 60．B 細節題，根據第一段It's not hard to guess．The top half of this fish looks like a small horse．可知，是因為海馬的頭部像馬而得名，故選B．
61．C 細節題，根據第二段It feeds on live food，such as small shrimps．可知它們以小蝦為食，故選C．
62．D 細節理解題．文章第三段介紹了海馬的繁殖過程．根據"Baby sea horses start out as eggs…the female gives her mate a new set of eggs．"可知答案為D．
63．B 細節理解題．最后一段提到海馬數量減少的兩個原因：一是人們填海造田，破壞了它們的生存環境；一是人們捕捉海馬來賣，故答案為B
點評 1、要想做好科普英語閱讀理解題，同學們就要注意平時多讀科普知識類文章，學習科普知識，積累常見的科普詞匯，從根本上提高科普英語的閱讀能力．
2、要熟悉科普類文章的結構特點．科普類文章一般由標題（Head line），導語（Introduction），背景（Back ground），主體（Main body）和結尾（End）五部分構成．標題是文章中心思想高度而又精辟的概括，但根據歷年的高考情況來看，這類閱讀理解材料一般不給標題，而要同學們選擇標題．導語一般位于整篇文章的首段．背景交待一個事實的起因．主體則對導語概括的事實進行詳細敘述，這一部分命題往往最多，因此，閱讀時，同學們要把這部分作為重點．結尾往往也是中心思想的概括，并與導語相呼應，命題者常在此要設計一道推理判斷題．
3、在進行推理判斷時，同學們一定要以閱讀材料所提供的科學事實為依據，同時所得出的結論還應符合基本的科普常識．
