Passage Three

Did you know that a turtle can lay twelve eggs in one minute？ A large sea turtle lays around 150 eggs at a time. She lays all these eggs in just a few minutes.

Large sea turtles live in the warm seas of the world. Except for when they lay their eggs, they spend their whole lives in water. When it is time to lay their eggs, the females swim to land. They usually return to the place where they themselves were born. How they find their way back there is a mystery.

When they reach shore, the big, heavy turtles crawl slowly up to the high water mark. Using their flippers, they pull themselves along the sand. They struggle like mountain climbers to attain their goal. When they finally reach dry sand, they rest before beginning the difficult task of laying eggs.

The turtles lay the eggs in deep holes and cover them with warm sand. The sand protects the eggs from harm. Then the females leave them. After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake in one spot. Then you would see tidy black balls coming out of the sand. The tidy heads of baby turtles!

Baby turtles have a build-in sense of direction. As soon as they are hatched, they head for the water. Once the babies swim out to sea, they don't touch shore again until it is time for them to lay their own eggs.

Sea turtles migrate across thousands of miles of ocean before returning to nest on the same stretch of coastline where they hatched, but how they do this has mystified scientists for more than fifty years. Sea turtles likely go to great lengths to find the places where they began life because successful nesting requires a combination of environmental features that are rare: soft sand, the right temperature, few predators, and an easily accessible beach. From this passage it is safe to conclude that sea turtles

A、are not easily observed by scientists.

B、cannot lay their eggs on any beach other than the one on which they hatched.

C、will not lay their eggs on beaches with pebbly sand.

D、must have the ability to precisely detect their location.

The sea lay like an unbroken mirror all around the pine - girt, lonely shores of Orr's Isl

and. Tall, kingly spruces wore their regal crowns of cones high in air, sparkling with diamonds of clear exuded gum; vast old hemlocks of primeval growth stood darkling in their forest shadows, their branches hung with long hoary moss; while feathery larches, turned to brilliant gold by autumn frosts, lighted up the darker shadows of the evergreens. It was one of those hazy, calm, dissolving days of Indian summer, when everything is so quiet that the faintest kiss of the wave on the beach can be heard, and white clouds seem to faint into the blue of the sky, and soft swathing bands of violet vapor make all earth look dreamy, and give to the sharp, clear-cut outlines of the northern landscape all those mysteries of light and shade which impart such tenderness to Italian scenery.

The funeral was over, --the tread of many feet, bearing the heavy burden of two broken lives, had been to the lonely graveyard, and had come back again, -- each footstep lighter and more unconstrained as each one went his way from the great old tragedy of Death to the common cheerful of Life.

The solemn black clock stood swaying with its eternal “tick - tock, tick -tock,” in the kitchen of the brown house on Orr's Island. There was there that sense of a stillness that can be felt, -- such as settles down on a dwelling when any of its inmates have passed through its doors for the last time, to go whence they shall not return. The best room was shut up and darkened, with only so much light as could fall through a little heart-- shaped hole in the window - shutter, -- for except on solemn visits, or prayer- meetings or weddings, or funerals, that room formed no part of the daily family scenery.

The kitchen was clean and ample, with a great open fireplace and wide stone hearth, and oven on one side, and rows of old - fashioned splint - bottomed chairs against the wall. A table scoured to snowy whiteness, and a little work - stand whereon lay the Bible, the Mixssionary Herald, and the Weekly Christian Mirror, before named, formed the principal furniture. One feature, however, must not be forgotten, -- a great sea - chest, which had been the companion of Zephaniah through all the countries of the earth. Old, and battered, and unsightly it looked, yet report said that there was good store within of that which men for the most part respect more than anything else; and, indeed, it proved often when a deed of grace was to be done -- when a woman was suddenly made a widow in a coast gale, or a fishing - smack was run down in the fogs off the banks, leaving in some neighboring cottage a family of orphans, -- in all such cases, the opening of this sea - chest was an event of good omen to the bereaved; for Zephaniah had a large heart and a large hand, and was apt to take it out full of silver dollars when once it went in. So the ark of the covenant could not have been looked on with more reverence than the neighbors usually showed to Captain Pennel's sea - chest.

The author describes Orr's Island in a(n) _______ manner.

A．emotionally appealing, imaginative

B．rational, logically precise

C．factually detailed, objective

D．vague, uncertain

根据以下材料，回答题

Sea Horses

Sea horses are unusual parents. The female sea horses lay the eggs， but unlike other creatures，it"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"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 bom 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？查看材料

A.Receiving eggs.

B.Laying eggs.

C.Hatching eggs.

D.Protecting eggs.
