Male sea horse have a fold of skin on their bellies that forms a pocket, called a brood pouch. During the breeding season, the sea horse’s pouch swells to receive eggs. A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses. The female will return every day to check on her mate and the eggs, but she doesn’t stay long, nor does she take part in the birth.
It takes from two to six weeks for the eggs in the male’s pouch to develop. During this time the male avoids open water and hides in sea grass. His big pouch makes it difficult for him to swim, so the male often uses his tail to grasp a piece of sea grass. Firmly, gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change his color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs.
The eggs hatch inside the male’s pouch. When the babies begin moving around, the male sea horse knows it’s time for them to be born. He grabs a sea grass stem with his tail and begins rocking, bending his body back and forth. This causes the opening to enlarge until it is wide enough for the first baby sea horse to shoot out. The father sea horse continues rocking, bending, and stretching his baby sea horse to shoot out. The father sea horse continues rocking, bending, and stretching his body so that the rest of the babies can be born. Sometimes he has to press his pouch against a rock or some stiff seaweed to force the young out.
Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tired when it’s over.
Soon after giving birth to one brood, the male will approach his mate and show her his empty pouch. This tells her he is ready to receive eggs again.

【选项释义】
What part does the female sea horse play in having babies? 雌海马在生孩子的过程中扮演什么角色？
A. Receive eggs. A. 接收卵子。
B. Laying eggs. B. 产卵。
C. Hatching eggs. C. 孵卵。
D. Protecting eggs. D. 保护卵子。
【考查点】事实细节题
【解题思路】根据题干关键词female sea horse和having babies定位到第一段第三、四句A female sea horse lays up to 200 eggs at a time in the pouch. Then she swims off, leaving her male partner to care for the developing eggs and give birth to young sea horses.（一只雌海马在育儿袋里一次能产200个卵。然后她游走了，留下她的雄性伴侣来照顾正在发育的卵和生下小海马。）据此可知，B选项属于正确答案。
【干扰项排除】
A选项根据第一段第一、二句Male sea horse have a fold of skin on their bellies that forms a pocket, called a brood pouch. During the breeding season, the sea horse’s pouch swells to receive eggs.（雄性海马的腹部有一层褶皱的皮肤，形成一个口袋，称为育儿袋。在繁殖季节，海马的育儿袋膨胀以接收卵子。）可知，接收卵子的是雄性海马，所以该选项属于张冠李戴；
C选项根据第三段第一句话The eggs hatch inside the male’s pouch.（卵在雄性的育儿袋里孵化。）可知该选项属于张冠李戴；
D选项根据第一段最后一句The female will return every day to check on her mate and the eggs, but she doesn’t stay long, nor does she take part in the birth.（雌海马每天都会回来看看她的配偶和卵，但她不会待太久，也不会参与生产。）可知雌海马不会保护卵子，该选项属于曲解原文。
第2题:
【选项释义】
What can be learned from the passage about giving birth to baby sea horses? 从这篇文章中我们可以了解到关于生小海马的什么信息？
A. It is dangerous for the female. A. 这对雌性来说很危险。
B. It happens once a year. B. 一年一次。
C. It is hard work for the male. C. 这对雄性来说是一项艰苦的工作。
D. It occurs in the deep sea. D. 它发生在深海中。
【考查点】推理判断题
【解题思路】这道题的定位放在全篇，除了产卵，生小海马工作是雄性海马完成的，可以做出初步判断C选项是对的，并且C项可以很明确的从倒数第二段得到信息Sea horse babies are born in groups of five or more. Sometimes it takes two days for the father sea horse to give birth to all his young. He is very tired when it’s over.（海马宝宝是五只或五只以上成群出生的。有时，海马爸爸要花两天时间才能产下所有的孩子。当它结束时，他很累。）根据其中的tired表明生小海马对雄性海马是一个艰苦的事情，故C项正确。
【干扰项排除】
A选项，雌海马除了产卵不参与生育过程，并且文中没有提到产卵是不是具有危险性，因此该选项属于无中生有；
C、D选项在文中没有提及，属于无中生有。
第3题:
【选项释义】
To protect himself and his eggs, the male sea horse does all the following EXCEPT ____. 为了保护自己和他的蛋，雄海马做了以下所有的事情，除了____。
A. changing his color A. 改变自己的颜色
B. gripping a piece of grass B. 抓一根草
C. staying motionless C. 静止不动
D. enlarging his pouch D. 扩大他的孵化袋
【考查点】事实细节题
【解题思路】D选项的信息在第三段的第三、四句，He grabs a sea grass stem with his tail and begins rocking, bending his body back and forth. This causes the opening to enlarge until it is wide enough for the first baby sea horse to shoot out.（他用尾巴抓住一根海草茎，开始摇晃，前后弯曲身体。这导致开口扩大，直到它足够宽，让第一个小海马射出来。）据此可知，扩大孵化袋是为了生育，而不是保护自己和宝宝。
【干扰项排除】
A、B、C选项可以在第二段找到相关信息，His big pouch makes it difficult for him to swim, so the male often uses his tail to grasp a piece of sea grass. Firmly, gripping the grass, he will stay perfectly still for hours or even days. The male sea horse will change his color to blend with his surroundings and avoid being seen by predators who will try to eat him or poke holes in his pouch to get the eggs.（他的大育儿袋使他很难游泳，所以雄性经常用他的尾巴抓一片海草。牢牢地抓住草，他会一动不动地待上几个小时，甚至几天。雄性海马会改变自己的颜色以融入周围环境，避免被捕食者发现，因为这些捕食者会试图吃掉他或在他的育儿袋上戳洞来获取卵。），所以不符合题意，属于反向干扰，排除。
第4题:
【选项释义】
The author suggests when sea horse babies are ready to be born ____. 作者提到当海马宝宝准备出生时____。
A. the male sea horse seems very happy A. 雄海马似乎很高兴
B. it is difficult for them to come out B. 他们很难出来
C. the female sea horse joins the male C. 雌海马加入了雄海马
D. they need large space in the pouch D. 他们的袋子需要更大的空间
【考查点】推理判断题
【解题思路】根据题干关键词born定位到第三段第二句，When the babies begin moving around, the male sea horse knows it’s time for them to be born.（当小海马开始四处走动时，雄海马就知道他们该出生了。）接着往后文阅读，He grabs a sea grass stem with his tail and begins rocking, bending his body back and forth. This causes the opening to enlarge until it is wide enough for the first baby sea horse to shoot out. （他用尾巴抓住一根海草茎，开始摇晃，前后弯曲身体。这导致开口扩大，直到它足够宽，让第一个小海马射出来。）可知在海马宝宝出生时，孵化袋需要扩大，所以D选项符合题意。
【干扰项排除】
A选项，在最后一段提到生育宝宝是累的，推断雄海马并不开心，而且文中没有明确的相关信息表明海马的心情，该项属于无中生有；
B选项在文中没有提及，属于无中生有；
C选项，在第一段的最后一句明确提出雌海马不会参与生产，该项属于反向干扰。
第5题:
【选项释义】
Which fact does the author want the reader to remember most? 作者最希望读者记住的事实是什么？

C. Baby sea horse are born in groups of five or more. C. 海马宝宝是五只或五只以上成群出生的。
D. The female will return every day to check on the eggs. D. 雌海马每天都会回来看蛋。
【考查点】观点态度题
【解题思路】全篇文章都在讲述雄海马生育后代，故作者最想让读者记住的就是这个事实，A项正确。
【干扰项排除】B、C、D选项在文章中都被提及，但都是细节，都被作者一笔带过，因此不符合题意。
