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'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'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, 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. What part does the female sea horse play in having babies？ A．Receiving eggs. B．Laying eggs. C．Hatching eggs. D．Protecting eggs.

For some fifty million years, despite all its eccentricities, the sea cucumber has subsisted on its diet of mud. It is adaptable enough to live attached to rocks by its tubefeet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of colors, ranging from black to reddish-brown to sand-color and white. One form. even has vivid purple tentacles. Usually the creatures are cucumber-shaped hence their name and because they are typically rock inhabitants, this shape, combined with flexibility, enables them to squeeze into crevices where they are safe from predators and ocean currents. Although they have voracious appetites, eating day and night, sea cucumbers have the capacity to become motionless and live at a low metabolic rate — feeding sparingly or not at all for long periods, so that the marine organisms that provide their food have a chance to multiply. If it were not for this faculty, they would devour all the food available in short time and would probably starve themselves out of existence. But the most spectacular thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it squirts all its internal organs into the water. It also casts off attached structures such as tentacles. The sea cucumber will eviscerate and regenerate itself when it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted. The passage mainly discusses A．the reason for the sea cucumber's name. B．what makes the sea cucumber unusual. C．how to identify the sea cucumber. D．places where the sea cucumber can be.

A．that B．this C．it D．them

A．look upon life as their elders do B．are more like American that their elders in their way of thinking C．look more like Americans than their elders D．expect more from Americans than from their elders

完型填空It seems quite clearly unjust to pay two people different amounts of money for doing the same work. But it is not as easy as it appeals at first __1__ to introduce equal pay for equal work. Two people may be working side by side in a factory and doing the same work, but one may be doing it twice as fast as the __2__; or one may be making no mistakes, while the other is making a lot. In some kinds of work, one can solve the problem of speed if one pays by the amount of work to be done and not by the hour: work paid for in this __3__ is called piece-work. But it is not always possible to do this, so it is sometimes useful to pay workers at different rates, which take differences in skill into __4__. This usually means that the younger and therefore less experienced worker gets less than the __5__ and more experienced one, which seems reasonable enough. 1.A：other B：sight C：older D：way E：account 2.A：other B：sight C：older D：way E：account 3.A：other B：sight C：older D：way E：account 4.A：other B：sight C：older D：way E：account 5.A：other B：sight C：older D：way E：account
