when the sun is lighting on it. We also know that it can be less pretty when the weather is terrible. What other things do we know about it？

The first thing is that the sea is very big. Look at a map of the world and you'll find there is less land than sea. The sea covers 3/4 of the world. The sea is very deep in some places. Some parts of the sea are very shallow. At a place near Japan, the sea is nearly 11 kilometres deep! If the highest mountain in the world were put into the sea at the place, there would be two kilometres of water above it.

Which of the following is true according to the passage？

A．The sea always looks pretty.

B．The sea always looks terrible.

C．The sea looks neither pretty nor terrible when it is fine.

D．The sea doesn't look pretty all the time.

ut erosion and the de posit of sediment(solid matter that settles at the bottom of a liquid)on the deep sea floor, but I'm confused. For that to happen, there would have to be some kind of force down there moving the mud or sand or whatever, right？ But I thought there weren't any waves or currents that deep in the ocean.

M: That's not exactly correct. It's true that deep down on the ocean floor we won't have the same kinds of currents we find in shallower parts. But we do find what we call turbidity currents. This wasn't in the book but the term came up in class. Do you remember what it means？

W: Umh, turbidity currents？ Oh, yeah! Isn't that when sediment like sand or mud gets stirred up and mixes with water. And then this mixture flows through the water around it, right？

M: Good !

W: Uhe, but I thought that only happened in rivers.

M: Well, yes. This does occur in rivers, but we see turbidity currents deep in the ocean as well.

W: But how do they get started there？

M: Earthquakes mostly, when an earthquake occurs under water, it throws up tremendous amounts of mud or sand that becomes suspended in a layer of water near the bottom of the ocean. This layer is so much denser and heavier than other ocean water that if flows right down the slopes of the ocean floor and gains more and more speed as it moves along. Then it's just like the winds blowing across the desert picking up sand from one place and moving it along and finally dropping it somewhere else.

A．The strength of ocean currents.

B．The movement of sediment deep in the ocean.

C．A new way of measuring the depth of the ocean.

D．The best methods for studying deep ocean processes.

monly known as Megalodon, is believed to have lived between I million and 5 million years ago and thought to have been 52 feet long. It is (or was) a shark that had a jaw 7 or more feet wide. Fairly recently, there has been some speculation about whether it is extinct or just out of reach. But few people believe that Megalodon has found a home deep in the ocean.

There are many known "Living Fossils": Coelacanth, Sea Cucumbers, Sea Urchins, Lobsters, Sea Stars. The common ones like lobsters and sea urchins are not really looked on as anything amazing. They've been around for thousands of years or more, and axe easily accessible to us. What if they weren't accessible and yet still existed？ We would label them extinct. The discovery of a live Coelacanth, a fish long believed extinct, challenged some scientists' long-held beliefs on extinction. There have been recent discoveries Of incredibly large squid, and deep-sea fish never before seen by scientists.

In the 1960s the U.S. Navy set up underwater microphones around the world to track Soviet submarines. The network, known as the Sound Surveillance System, still lies deep below the ocean's surface in a layer of water known as the "deep sound channel'. The temperature and pressure of the channel allow sound waves to travel undisturbed. NOAA's Acoustic Monitoring Project has been using the Sound Surveillance System to listen for changes in ocean structure like ocean currents or volcanic activity. Most of the sounds recorded are common and of no concern. One sound, identified in 1977 by U.S. Navy "spy" sensors, was odd. It was obviously a marine animal but the call was more powerful than any of the calls made by any other reported sea creature. It was too big for a whale. Could it be a deep-sea monster？ One possibility was a giant squid, but no one is sure. It was named "Bloop". Could it be Megalodon？ If Megalodon is still alive down in the bottom of the ocean, we may some day soon discover it. Then what？ Deep sea diving will never be the same, that's for sure!

The following is commonly known EXCEPT ________.

A．Megalodon, the largest shark, is extinct

B．Megalodon is not extinct but just out of reach

C．Megalodon was 52 feet long and had a jaw 7 or more feet wide

D．Megalodnn lived between several million years ago

a picture of a mountain, know the deep satisfaction that can be found in art. It is not easy to express this satisfaction in words. But, in some partly mysterious (神秘的) way, works of art are among the things of highest value in our lives.

A fine piece of music, a masterpiece of painting, or a first-class play has the power to hold our fullest attention. We are completely lost in it, and everything works out right. The music comes to the right close at the right time and in the right way. The play ends, not necessarily on a happy note, but in a way that seems enjoyable. As we get to know more about painting, its parts seem to belong together and to be made for one another. We see harmony (和谐) in the object and feel harmony within ourselves.

When the beautiful experience has ended, we often feel uplifted and refreshed. Our eyes and ears, or our understanding of other persons and values, may be sharpened and improved. We may feel more at home with ourselves. Works of art have value for us in some such ways as these.

It is this value that marks the difference between great art and simple entertainment(娱乐). A work that is fairly easy to understand takes little effort on our part. It may give us pleasure, but it does not touch our feelings or attract out attention at a deep level.

What is the main idea of the text？

A．Music has a power to catch all our attention.

B．Art of high values can improve us as human beings.

C．It's difficult to express our satisfaction from works of art.

D．Simple entertainment is easy to understand and can give us pleasure.

he path led into some very thick bushes. Rather than go through these, I decided that if we walked a- long the bottom of this valley we could climb up again and rejoin the path on the far side of the bushes.

As I climbed down into the valley a bird flew off a rock on which I had put my hand. On looking at the spot where the bird had risen I saw two eggs. They were a kind that I did not have in my collection, so I placed them carefully in my bag, wrapped in a little dry grass.

As we went further down the valley the sides became steeper and not far from where I had entered it. I came to a drop of about twelve to fourteen feet. The water that rushed down all these small valleys in the rainy season had made the rock as glass. As it was too deep to climb down, I handed my gun to one of the men and slid down it. My feet had hardly touched the sandy bottom when the two men jumped down, one on each side of me. They quickly gave me the gun and asked me if I had heard the tiger. Actually, I had heard nothing, perhaps because of the noise I made sliding down the rock. The men said they had heard a tiger growling somewhere nearby, but they did not know from which direction the noise had come.

According to the passage we know that_________.

A．the writer decided to push through the thick bushes

B．the writer decided to walk along the valley

C．the writer wanted to stop climbing

D．the writer tried to find two eggs

l disposition, he was my constant companion throughout my teenage years. We would play together in the garden, and take long walks over the hills behind the house and on the beach. Benji would hang on my every word with his head tilted to one side. Despite being a dog, he seemed to have a sympathy for my problems that went deeper than words could express. He was my best friend.

Benji left us about 15 years ago for that great kennel in the sky. But recently I've been thinking about him a lot. Was he really conscious？ Could any animal have consciousness like we do？ Does it matter whether animals are conscious or not？

For many, it is a matter of life and death. On the one hand, animal research has helped prevent some of the most pressing human diseases, including hepatitis B, hepatitis C, "mad cow" disease, malaria, cystic fibrosis and emphysema. On the other hand, this research is performed largely on chimps, our closest nonhuman relatives, with whom we share 98.4% of our genetic material, and great apes, with whom we are similarly biologically close.

Some people feel this connection is strong enough to warrant special treatment. An international group called the Great Ape Project is lobbying the United Nations to adopt a declaration on the rights of great apes modeled on the UN declaration On the Rights of Man. The group believes that apes are "conscious" and so deserve legal protection of their right to life and freedom from imprisonment and torture.

If great apes were shown to have consciousness or something like our own, I would consider it among the scientific discoveries of the century. I would then agree with the Australian philosopher and founder of the animal rights movement, Peter Singer, that performing medical experiments on chimps would be like experimenting on orphan children. That's a pretty chilling thought, and no amount of human suffering saved could justify such an action. But before we close down the laboratories and stop searching for a vaccine against AIDS, we had better take a long hard look at the evidence for ape consciousness.

Why does the author bring up the example of Benji？

A．To show that animals have consciousness.

B．To raise the question of animal consciousness.

C．Because Benji was his best friend.

D．To illustrate the differences between dogs and chimps.

听力原文： Bad as well as good moods spice life and build character. The key is balance.

We often have little control over when we are swept by emotion. But we can hove some say in how long that emotion will last. Psychologist Dianne Tice of Case Western Reserve University asked more than 400 men and women about their strategies for escaping bad moods. Her research, along with that of other psychologists, provides valuable information on how to change a bad mood.

Of all the moods that people want to escape, rage seems to be the hardest to deal with. When someone in another car cuts you off on the highway, your thought may be, That jerk ! He could have hit me ! I can't let him get away with that! The more you stew, the angrier you get. Such is the stuff of hypertension and reckless driving.

What should you do to relieve rage？ One myth is that ventilating will make you feel better. In fact, researchers have found that's one of the worst strategies. Outbursts of rage pump up the brain's arousal system, leaving you much angrier, not less.

A more effective technique is "reframing," which means consciously reinterpreting a situation in a more positive light. In the case of the driver who cuts you off, you might tell yourself: Maybe he had some emergency. This is one of the most potent ways, Tice found, to put anger to rest.

Going off alone to cool down is also an effective way to defuse anger, especially if you can not think clearly. Tice found that a large proportion of men cool down by going for a drive—a finding that inspired her to drive more defensively. A safer alternative is exercise, such as taking a long walk. Whatever you do, don't waste time pursuing your train of angry thoughts.

Your aim should be to distract yourself.

The techniques of reframing and distraction can alleviate depression and anxiety as well as anger. Add to them such relaxation techniques as deep breathing and meditation and you have a store of weapons against bad moods. "Praying, "Dianne Tice also says, "works for all moods."
