Although man has known asbestos for many hundreds of years, it was not until 160 years ago that it was mined for the first time on the North American continent. H. W. Johns, owner of a New York City Supply Shop for roofers, was responsible for he opening of that first mine.
Mr. Johns was given a piece of asbestos which had been found in Italy. He experimented with the material and then showed its surprising powers to his customers. After putting on a pair of asbestos gloves, which looked much like ordinary work gloves, he took red-hot coals from the fireplace and played with them in his hands. How astonished the customers were to discover that he was not burned at all. You can well imagine that he had increasing business in asbestos roofing materials. However, because it was very expensive to transport them from Italy to the United States, Mr. Johns sent out a young scientist to seek a source nearer home. This young man found great vein in the province of Quebec in Canada.
Ever since 1881 Quebec has led the world in the production of this unusual mineral, which is made up of magnesium, silicon, iron, and oxygen. When it is mined, the asbestos is heavy, just as you would expect a mineral to be. When it is separated, a strange thing happens; the rock breaks down into fine, soft, soapy fibers .
Scientists do not know why the rock can be separated easily into threads,but they have found thousands of uses of this fireproof material, of the so-called “cloth of stone”.

Researchers at San Diego Zoo have been studying what has been described as the “secret language” of elephants. They have been monitoring(监测) communications between animals that cannot be heard by human ears.
The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.Why some elephants’ call is called “secret language”?
A.Because it can’t be heard by human ears. |
B.Because it can only be heard by female elephants. |
C.Because people don’t know its meanings. |
D.Because people haven’t studied it completely. |
By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out .
A.where the elephants usually go |

A.The elephants can speak like people. |
B.The wild elephants’ ways to fight against enemies. |
C.The “secret language” between elephants. |
D.The special life of female elephants. |
Kataria is the founder of the worldwide laughter movement. The celebration of world Laughter Day is a positive activity for world peace and is intended to build up a global sense of brotherhood and friendship through laughter. The first “World Laughter Day” gathering took place in Mumbai, India, on 11th January 1998. 12,000 members from India and international Laughter Clubs attended it. Now there are over 5,000 Laughter Clubs worldwide on all 5 continents.
“HAPPY-DEMIC” was the first World Laughter Day gathering outside India. It took place on 9th January 2000. In Copenhagen, Denmark , more than 10,000 people gathered at Town Hall Square. The event went into Guinness Book of World records. “World Laughter Day” is now organized on the first Sunday of May every year. Hundreds of people gather worldwide on that day to laugh together.
Today, many people fear widespread international terrorism(恐怖主义). The world has never faced so much unrest before. People are at war within themselves. Laughter is a universal language, which has the ability to unite humanity without religion(宗教). Laughter can build a common connection between various religions and create a new world order. The idea may sound over-ambitious (野心太大的), and maybe it is. But maybe it is not. It is our deep belief that laughter and only laughter can unite the world, building up a global sense of brotherhood and friendship.
Studies also say that laughter helps your body do the following: lower blood pressure; lighten depression; reduce stress; work out the heart, especially for those who are unable to perform physical exercise. So in life, when you can laugh, you should laugh loudly and with your entire body—because it’s good for you.The purpose of celebrating World Laughter Day is ____.

Given Australia’s size and the fact that early settlements were far apart, Australian society is remarkably homogeneous (同种的). Its citizens are fundamentally prosperous and the way of life in the major cities and towns is much the same however many miles divide them. It takes a sharp ear to identify regional accents. However, there is some difference in lifestyle between city dwellers and the country people. Almost 90 per cent of the population lives in the fast-paced cities along the coast and has little more than a passing familiarity with the desert. The major cities preserve pockets of colonial heritage, but the overall impression is modern, with new buildings reflecting the country’s youth. In contrast, the rural communities tend to be slow-moving and conservative. For many years, Australia was said to have “ridden on the sheep’s back”, a reference to wool being the country’s main money earner. However, the wool industry is no longer dominant. Much of Australia’s relatively sound economy is now achieved from natural coal and wheat, and by being the largest diamond producer in the world. Newer industries such as tourism and wine making are also increasingly important. Australians are generally friendly and relaxed, with a self-deprecating sense of humor. On the whole, Australia is a society without hierarchies (等级制度), an attitude generally held to stem from its prisoner beginnings.
Yet, contrary to widespread belief, very few Australians have true prisoner origins. Within only one generation of the arrival of the First Fleet in 1788, Australia had become a nation of immigrants. Originally coming almost entirely from the British Isles, today one in three Australians comes from elsewhere. Australia’s liberal postwar immigration policies led to an influx of survivors from war-torn Europe, most notably Greeks, Italians, Poles and Germans.
The emphasis has shifted in recent years and today the majority of new immigrants are from Southeast Asia. Today Australia is a ‘blend of nations’ and although some racism exists, it has generally been a successful experiment and the country is justifiably proud to have one of the most harmonious multicultural communities in the world.What does the writer mean by saying “It takes a sharp ear to identify regional accents.” in the first paragraph?
A.Australians speak Standard English with no local accents whatsoever. |
B.You have to practice a lot to learn to understand the different accents. |
C.The Australian regional accents are very difficult to understand indeed. |
D.There is not much difference between the accents in different areas of Australia. |
Which of the following statements is TRUE according to the passage?
A.Most Australians have ancestors who were prisoners. |
B.The Australian economy is dependent on sheep exports. |
C.The majority of people living in Australia come from Europe. |
D.The pace of life is different in the city and in the country. |
The underlined pronoun ‘it’ in the final paragraph refers to “_______”.
A.Community | B.racism | C.blend of Nations | D.Southeast Asia |
We can infer from the passage that _____.
A.there are no signs of Australia’s colonial past in its modern cities |
B.Australia’s recent immigration policy encourages immigrants from Southeast Asia |
C.immigrants from Southeast Asia have brought racial problems |
D.“riding on sheep’s back” resulted in slow development in rural communities |
Why do people drink too much, eat too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip (啜饮) of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette — it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.What do most people think causes bad behavior?
A.Being forced by others. |
B.Not having enough will power. |
C.Enjoying their first experiences. |
D.Following the examples of their friends. |
The author mentions his experience in the third paragraph to prove ____.
A.will power helps develop bad habits sometimes |
B.drinking beer is harmful to the health of teenagers |
C.self-control should be developed when one is young |
D.everyone can be challenged by different temptations |
In the last paragraph, the author stresses that ____.
A.without self-control, no one can succeed |
B.bad habits don’t always lead to bad results |
C.applying self-control correctly is important |
D.people can develop wisdom from bad behavior |
What would be the best title for the passage?
A.My First Sip of Beer | B.Do You Have Will Power ? |
C.Does Will Power Benefit Us? | D.Dark Side of Self-control |
It’s really true what people say about English politeness: it’s everywhere. When squeezing (挤过去) past someone in a narrow passage, people say “sorry”. When getting off a bus, English passengers say “thank you” rather than the driver. In Germany, people would never dream of doing these things. After all, squeezing past others is sometimes unavoidable, and the bus driver is only doing his job. I used to think the same way, without questioning it, until I started traveling to the British Isles, and here are some more polite ways of interacting (交往) with people in UK.
People thank each other everywhere in England, all the time. When people buy something in a shop, customer and shop assistant in most cases thank each other twice or more. In Germany, it would be exceptional to hear more than one thank you in such a conversation. British students thank their lecturers when leaving the room. English employers thank their employees for doing their jobs, as opposite to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize (批评) others. Even when I was working and mistakes were pointed out to me, my employers emphasized several times but none of their explanations were intended as criticism. It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable. This also is showed in other ways. British men still open doors for women, and British men are more likely to treat women to a meal than German men. However, I do need to point out here that this applies to English men a bit more than it would to Scottish men! Yes, the latter are a bit tightfisted.What is the author’s attitude towards English politeness?
A.He thinks it is unnecessary. | B.He thinks little of it. |
C.He appreciates it very much. | D.He thinks it goes too far. |
What can be inferred from the passage?
A.German men never treat a woman to dinner. |
B.The author think it’s unnecessary to say “thank you” to the bus driver. |
C.In Germany, employers often say “thank you” to employees for their job. |
D.Germans think it is unnecessary to thank workers because payment is enough. |
We can learn from the last paragraph that Scottish men ______.
A.like to fight with each other |
B.treat women in a polite way |
C.are as generous as English men |
D.are unwilling to spend money for women |
The author develops the text through the method of ______.
A.making comparisons | B.telling stories |
C.giving reasons | D.giving examples |
