Question

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 （育儿袋）．"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．

点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．
