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．

Answer 1

分析 本文主要講解了有關(guān)海馬的知識(shí)，講到了海馬名字的來歷，生活習(xí)性，如何繁殖及數(shù)量越來越少的原因．

解答 60．B 細(xì)節(jié)題，根據(jù)第一段It's not hard to guess．The top half of this fish looks like a small horse．可知，是因?yàn)楹ｑR的頭部像馬而得名，故選B．
61．C 細(xì)節(jié)題，根據(jù)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(xì)節(jié)理解題．文章第三段介紹了海馬的繁殖過程．根據(jù)"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(xì)節(jié)理解題．最后一段提到海馬數(shù)量減少的兩個(gè)原因：一是人們填海造田，破壞了它們的生存環(huán)境；一是人們捕捉海馬來賣，故答案為B

點(diǎn)評(píng) 1、要想做好科普英語(yǔ)閱讀理解題，同學(xué)們就要注意平時(shí)多讀科普知識(shí)類文章，學(xué)習(xí)科普知識(shí)，積累常見的科普詞匯，從根本上提高科普英語(yǔ)的閱讀能力．
2、要熟悉科普類文章的結(jié)構(gòu)特點(diǎn)．科普類文章一般由標(biāo)題（Head line），導(dǎo)語(yǔ)（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來看，這類閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語(yǔ)一般位于整篇文章的首段．背景交待一個(gè)事實(shí)的起因．主體則對(duì)導(dǎo)語(yǔ)概括的事實(shí)進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時(shí)，同學(xué)們要把這部分作為重點(diǎn)．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語(yǔ)相呼應(yīng)，命題者常在此要設(shè)計(jì)一道推理判斷題．　　
3、在進(jìn)行推理判斷時(shí)，同學(xué)們一定要以閱讀材料所提供的科學(xué)事實(shí)為依據(jù)，同時(shí)所得出的結(jié)論還應(yīng)符合基本的科普常識(shí)．
