Analysis of the composition of quicksand shows that there are four key ingredients—sand, obviously water, clay and salt. Together these materials form a structure resembling a house of cards, with large water-filled gaps between the sand particles, which are loosely glued in place by the clay. As long as it’s left alone, the structure remains stable. But as soon as it’s disturbed, by stepping on it, the clay changes from a jelly-like consistency to a runny liquid. The effect is the same as stirring a pot of yoghurt. Liquefying(溶解)the clay makes the quicksand about one million times runnier, and the whole house of cards comes tumbling down, with you inside it.
Very quickly, the sand sinks to the bottom and the water floats to the top. This is where the salt comes in. When there’s enough salt present, as soon as the clay particles liquefy, electrical charges make them begin to stick together to form bigger particles and these also settle with the sand. Quicksand is a mixture which looks like solid, but behaves more like a liquid.
Despite its murderous reputation, quicksand does not such people under and swallow them, although it can hold a person in firm grip. The human body is more buoyant(有浮力) in quicksand than in water, and sooner or later anyone trapped in it will float.
Unlike most liquids, quicksand’s viscosity, or “runniness” can suddenly change if it comes under pressure, for example under a human foot. The surface gives way and the victim quickly sinks in up to the knees, surrounded by an area of dirty things that turns semi-solid around its victim. Escaping from the quicksand’s grip(紧握) requires a large amount of force. Without something solid to pull at, people often find they are stuck fast. Pulling at one leg simply makes the other one sink further.
So how do you escape from quicksand’s control? Stay still and call for help. Staying still stops you sinking any further, until--with luck--help arrives on the scene. If no one appears and you need to draw yourself out, gently lie down on your back until your body is floating on the sand. Next, roll over onto your stomach and pull yourself forwards with your hands, so that you gradually “swim” towards firmer ground. It is a slow and dirty business, but it works.
This technique has one barrier: it goes against a very powerful human nature. Faced with danger in the open, nine out of ten stay on their feet so that they can run away, in which case it can worsen the situation.Which ingredient of the quicksand make someone trapped in it stuck and stuck fast?

CARDIFF, Wales Poets, singers and musicians from across the globe gathered in Wales to celebrate the tradition(传统) of storytelling.
“It might seem strange that people still want to listen in age of watching television, but this is an unusual art form whose time has come again,” said David Ambrose, director of Beyond the Border, an international storytelling festival(节) in Wales.
“Some of the tales, like those the Inuit from Canada, are thousands years old. So our storytellers have come from distant lands to connect us with the distance of time,” he said early this month.
Two Inuit women, both in their mid 60s, are among the few remaining who can do Kntadjait, or throat singing, which has few words and much sound. Their art is governed by the cold of their surroundings, forcing them to say little but listen attentively.
Ambrose started the festival in 1993, after several years of working with those reviving (coming back into use or existence) storytelling in Wales.
“It came out of a group of people who wanted to reconnect with traditions. and as all the Welsh are storytellers, it was in good hands here.” Ambrose said.Ambrose believes that the art of storytelling _______.

Lucky is the man who has no “skeleton in his closet”. When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a “skeleton in his closet”. Some people may have more than one skeleton.
As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England.
Before 1932, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse(尸体) of an executed(处决) criminal.
But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices.
We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor would keep his skeleton in some dark corner where it could not be seen, or hide it in a closet.
After a time, people began to suspect(怀疑) every doctor of hiding a skeleton in the closet. From this suspicion, the phrase “a skeleton in the closet” took on a broader, more general meaning to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory.
One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man’s guess is as good as another. But this sounds like a story by the great French novelist, Balzac.
Baizac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly hides her lover in the closet of her bedroom. He enters her room and asks her if she is hiding her lover. He says he will not open the door to the closet if she promises him there is no one there; He will believe her. She answers firmly that she is not hiding anyone in the closet.
The husband then begins to build a solid brick wall against the closet. His wife watches, knowing that her lover will never come out alive. But she will not change her story and admit her guilt.Which of the following situations is suitable for using the phrase “skeleton in the closet” ?
| A．You have stolen something precious and don’t want it discovered. |
| B．You are a doctor and have to keep a skeleton for research. |
| C．If you have cut open a dead human body for scientific examination you should keep the skeleton secret. |
| D．You have done a crime or done something foolish, but you want to keep other from discovering it. |
From the text we know that there are _______ theories about how the phrase “skeleton in the closet” came into being.
| A．one | B．two | C．three | D．four |
In Chinese the world “skeleton” means _______.
| A．尸体 | B．标本 | C．收藏 | D．骷髅 |

| D．It was legal that corpses of anybody were cut open for scientific examination in history. |

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have travelled to the places. Or you can go and see a colour film. Or you can read travel books.
It would seem that there are three kinds of travel books. The first are those that give a personal, subjective(主观的) account of travels which the author has actually made himself. if they are informative and have a good index(索引), then they can be useful to you when you are planning your travels. The second kind are those books whose purpose is to give a purely objective(客观的) description of things to be done and seen. If a well-read, cultured person has written such a book, then it is even more useful. It can be sorted as a selected guide book. The third kind are those books which are called “a guide” to some place or other. If they are good, they will, in addition to their factual information, give an analysis or an explanation. Like the first kind they can be inspiring and interesting. But their basic purpose is to help the reader who wishes to plan in the most practical way.
Whatever kind of travel book you choose you must make sure that it does not describe everything as “wonderful”, “excellent” or “magical”. You must also note its date of publication because travel is a very practical affair and many things change quickly in the twenty-first century. Finally, you should make sure that the contents are well presented and easy to find.This passage is about _______.

To face the music
Like every language, American English is full of special expressions, phrases that come from the day-to-day life of the people and develop in their own way. Our expression today is “to face the music”.
When someone says, “well, I guess I’ll have to face the music,” it does not mean he’s planning to go to the concert. It is something far less pleasant, like being called in by your boss to explain why you did this and did that, and why you didn’t do this or that. Sour music indeed, but it has to be faced. At sometime or another, every one of us has had to face the music, especially as children. We can all remember father’s angry voice, “I want to talk to you.” and only because we did not obey him. What an unpleasant business it was!
The phrase “to face the music” is familiar to every American, young and old. It is at least 100 years old. And where did this expression come from? The first explanation comes from the American novelist, James Fenimore Looper. He said, in 1851, that the expression was first used by actors while waiting in the wings to go on the stage. When they got their cue to go on, they often said, “Well, it’s time to face the music.” And that was exactly what they did — facing the orchestra which was just below them. And an actor might be frightened or nervous as he moved on to the stage in front of an audience that might be friendly or perhaps hostile, especially if he forgot his lines. But he had to go out. If he did not, there would be no play. So the expression “to face the music” come to mean “having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice.”
Other explanations about the expression go back to the army. When the men faced an inspection by their leader, the soldiers would be worried about how well they looked. Was their equipment clean, shinny enough to pass the inspection? Still the men had to go out and face the music of the band as well as the inspection. What else could they do?
Another army explanation is more closely related to the idea of facing the results and accepting the responsibility for something that should not have been done. As, for example when a man is forced out of the army because he did something terrible, he is dishonored. The band does not play. Only the drums tap a sad, slow beat. The soldier is forced to leave, facing such music as it is and facing the back of his horse. How many ways does the phrase “to face the music” comes from?
| A．1 | B．2 | C．3 | D．4 |
What’s the meaning of “to face the music?”
| A．To face something far less pleasant. |
| B．To face the stage. |
| C．To face the back of one’s horse. |
| D．To face one’s leader. |
Which of the following is a situation of facing the music?
| A．When we are playing basketball. |
| B．When we are making a speech. |
| C．When we are having a party. |
| D．When we are talking with somebody. |
The underlined word “hostile” means _______.
| A．unfriendly | B．dislike | C．unkind | D．unnecessary |
Informal conversation is an important part of any business relationship. Before you start a discussion, however, make sure you understand which topics are suitable and which are considered taboos(禁忌) in a particular culture. Latin Americans enjoy sharing information about their local history, art, and customs. They expect questions about their family and are sure to show pictures of their children. Yon may feel free to ask similar questions of your Latin American friends. The French think of conversation as an art form, and they enjoy the value of lively discussions as well as disagreements. For them, arguments can be interesting — and they can cover pretty much or any topic — as long as they occur in a respectful and intelligent(智慧的) manner.
In the United States, business people like to discuss a wide range of topics, including opinions about work, family, hobbies, and politics. In Japan, China, and Korea, however, people are much more private. They do not share much about their thoughts, feelings, or emotions because they feel that doing so might take away from the harmonious(和谐的) business relationship they’re trying to build. Middle Easterners are also private about their personal lives and family matters. It is considered rude, for example, to ask a businessman from Saudi Arabia about his wife or children.
As general rule, it’s best not to talk about politics or religion(宗教) with your business friends. This can get you into trouble, even in the United States, where people hold different views. In addition, discussing one’s salary is usually considered unsuitable. Sports is typically a friendly subject in most parts of the world, although be careful not to criticize a national sport. Instead, be friendly and praise your host’s team.The author considers politics and religion ________.
| A．cheerful topics | B．taboos |
| C．rude topics | D．topics that can never be talked about |
Which is typically a friendly topic in most places according to the author?
| A．Sports. | B．Children. |
| C．Personal feelings. | D．Families. |
