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.

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

根据以下材料，回答题。

What We Take From and Give to the Sea

As long as we have been on earth， we have used the sea around us. We take things from the ocean， and we give to it.

We take fishes from the ocean——millions of kilograms of fish， every year， to feed millions of people. （46） We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates. （47） Much gold and silver drift dissolved in the waters of the sea， too. But the sea does not give them up by simple evaporation.

Other gifts from the sea are pearls， sponges and seaweed. Pearls become jewelry. （48）Seaweed becomes food of many kinds——even candy， and ice cream——as well as medicine. Believe it or not， fresh water is another gift from the sea. We cannot drink ocean water. （49）But ocean water becomes fresh water when the salts are removed. In the future， we will find ourselves depending more and more on fresh water from the sea.

The sea gives us food， fertilizer， minerals， water， and other gifts. What do we give the sea？ Garbage. （50） Huge as it is， the ocean cannot hold all the water we pour into it Dumping garbage into the ocean is killing off sea life. Yet as the world population grows， we may

need the sea and its gifts more than ever.

We are finally learning that if we destroy our sea， we might also destroy ourselves. Hopefully， it is not too late.

A.Natural sponges become cleaning aids.

B.We pollute the ocean when we use it as a garbage dump.

C.The area of the sea is becoming smaller anal smaller.

D.Along with salt， other minerals are left after evaporation.

根据以下材料，回答题

What Is Anthrax （炭疽）？

There"s been a lot of talk about anthrax on the news lately. Some people are worried that anthrax may be connected to terrorist attacks or that terrorists may spread the germ that 51_______ the disease.

Federal officials and police are investigating this and taking 52_______ to protect us.

In the meantime， it"s important not to panic over anthrax. The chances that you and your family 53_______ at risk are very tiny. One of the ways you can feel better is to learn about anthrax.

When you know what it is and 54_______ you can get it， it doesn"t seem quite as scary.

So， what 55_______ is anthrax？

Here are the facts on anthrax:

根据以下材料，回答题EarthquakeEarthquake may rightly be ranked as one of the most destructi

根据以下材料，回答题

Earthquake

Earthquake may rightly be ranked as one of the most destructive forces known to man: since records began to be written down， it has been estimated that earthquake-related fatalities have numbered in the million， and that earthquake-related destruction has been beyond calculation. The greater part of such damage and loss of life has been due to collapse of buildings and the effects of rockslides， floods， fire， disease， tsunamis （gigantic sea waves）， and other observable events resulting from earthquake， rather than from the quakes themselves.

The great majority of all earthquakes occur in two specific geographic areas. One such area covers the Pacific Ocean and its bordering landmasses. The other extends from the East Indians to the Atlas Mountains， including the Himalayas， Iran， Turkey， and the Alpine regions. It is in there two great belts or zones that ninety percent of all earthquakes take place; they say， however， happen anywhere at any time.

This element of the unknown has for centuries added greatly to the dread and horror surrounding earthquakes， but in recent times there have been indications that earthquake forecast may be possible. By analyzing changes in animal behavior， pattems of movements in the earth"s shell，variations in the earth"s force of attraction， and the frequency with which minor earth shakes are observed， scientists have shown increasing success in expecting when and where earthquakes will strike. As a result， a worldwide earthquake warning network is already in operation and has helped to prepare for （and thus lessen） the vast destruction that might otherwise have been totally unexpected.

It is doubtful that man will ever be able to control earthquakes and get rid of their destructiveness altogether， but as how and why earthquakes happen become better understood， man will become more and more able to deal with their possible damage before they occur.

Which of the following statements is true according to the passage？查看材料

A.Earthquake destruction is declining.

B.Earthquake forecast is improving.

C.Man is no longer fearful of earthquakes.

D.Man is capable of conquering earthquakes.

根据材料，回答题。

A Ride in a Cable-car

A ride in a cable-car is one of the exciting and enjoyable experiences a child can have. In Switzerland， which is the home of the cabie-car， it is used mostly to take tourists up the slope of a mountain， to a restaurant from which one can have a bird-eye view of the surrounding country， or to a top of a ski-run， from which， in winter， skiers glide down the snow covered the slope on skis. In Singapore， however， the cable-car takes one from the summit of a hill on the main island to a low hill on Sentosa， a resort island just off the southern coast.

The cable-car is really a carriage which hangs from a strong steel cable suspended in the air. It moves along the cable with other cars on pulleys， the wheels of which are turned by electric motors. The cars are painted in eye-~catching colours and spaced at regular intervals. Each car can seat up six persons. After the passengers have entered a car， they are locked in from outside by an attendant， they have no control over the movement of the car.

Before long， the passengers get a breath-taking view through the glass windows of the modern city， the bustling harbour， and the several islands off the coast. The car is suspended so high in the air that slips on the sea look like small boats， and boats like toys. On a clear day， both the sky above and the sea below look beautifully blue.

In contrast to the fast-moving traffic on the ground， the cars in the air move in a leisurely manner， allowing passengers more than enough time to take in the scenery during the brief trip to the island of Sentosa. After a few hours on Sentosa， it will be time again to take a cable-car back to Mount Faber. The return journey is no less exciting than the outward trip.
