Sea Horses
Sea horses are unusual parents. The female sea horses lay the eggs, but unlike other creatures,it&39;s the males that give birth to the young.
Male sea horses have a fold of skin on their bellies that forms pocket, called a brood pouch.
During the breeding season, the sea horse&39;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 everyday to check on her mate and the eggs, but she doesn&39;t stay long, nor does she take part in the birth.
It takes from two to six weeks for the eggs in the male&39;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&39;s pouch. When the babies begin moving around, the male sea horse knows it&39;s time for them to be born. He grabs a sea grass stem with his tail and begins 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&39;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.

未知题型 根据短文的内容，回答下列题目They Say Ireland&39;s the BestIreland is the best place in the world to live in for 2005, according to a life quality ranking that appeared in Britain&39;s Economist magazine last week.The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction and well-being.The index of 111 cotmtries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family and community life".Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality,and the high cost of living. Ireland scored an impressive 8.33 points out of 10.That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity and hunger, is rated the gloomiest (最差的), picking up only 3.89 points."Although rising incomes and increased individual choices are highly valued," the report said,"some of the factors associated with modernization such as the breakdown (崩溃) in traditional institutions and family values in part take away from a positive impact.""Ireland wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family and community life."The magazine admitted measuring quality of&39;life is not a straightforward thing to do, and that its findings would have their critics.No.2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg,Sweden, Australia, Iceland, Italy, Denmark and Spain. The UK is positioned at No.29, a much lower position chiefly because of the social and family breakdown recorded in official statistics.The US, which has the second highest per capita GDP (人均国内生产总值) after Luxembourg,took the 13th place in the survey. China was in the lower half of the league at 60th.For 2，005 years， Ireland has been the best place for humans to live in. 查看材料
