听力原文： Scientists say sharks have lived in the world's oceans for millions of years. Scientists say there are more than 350 different kinds of sharks.
Sharks do not have bones, and a shark has an extremely good sense of smell. It can find. small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. Sharks also sense electrical and magnetic power linked to nerves and muscles of living animals. These powerful senses help them find their fond. Some sharks will eat just about anything. Many unusual things have been found in the stomachs of some large sharks. They include shoes, dogs, a cow's foot and metal protective clothing.
About forty percent of the different kinds of sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies like humans do.
Scientists are beginning to understand the importance of sharks to humans. Medical researchers want to learn more about the shark's body defense system against disease. They know that sharks recover quickly from injuries. Sharks appear never to suffer infections, cancer or heart diseases.
What is this passage mainly about？
A．The necessity of protecting sharks.
B．The living environment of sharks.
C．The dangers of sharks to human beings.
D．An introduction to sharks.

Darwin's great work, The Origin of Species, is now generally accepted as one of the most important books ever written. But when it first came out in 1859, it was both derided and bitterly condemned by scientists and laymen.
Much of opposition to The Origin of Species arose from Darwin's claim that all living creatures, including man, are somehow related. Many people were outraged by the suggestion that man shared a common ancestor with animals such as apes and monkeys. They attacked Darwin for saying that man had descended from the apes.
But Darwin never actually said this. He believed that modern men and modern apes have both descended from the same ancestor. But at some time in pre-history, millions of years ago, men and apes began to develop separately, and ever since have continued to take on different characteristics. Today, more than 90 years after Darwin's death, this is the opinion which scientists continue to hold.
In his works, Darwin described the progression of life from its earliest forms. First came the invertebrate-creatures without a backbone. Then invertebrates evolved into fish; fish into amphibians; amphibians into reptiles; and reptiles into birds and mammals.
Fossil remains found after his death show that Darwin was right. Perhaps the most amazing fact about his theory is that he managed to work it out with the aid of only a few fossil discoveries.
Fossil remains were not the only information which we now possess but which Darwin lacked. He did not know that apes have the same diseases as men; nor that they and men have the same kind of blood. Nor did he know about the modern uses of radiation which enable scientists to tell the age of fossil remains and so estimate the speed at which evolution has taken place.
Which of the following best describes the passage as a whole？
A．The Origin of Species is a very significant book.
B．Darwin's discoveries were proved to be right though the Origin of Species was severely attacked.
C．The evolution of men has gone through a very long process.
D．It was impossible for Darwin to prove his ideas only with the aid of fossils.

In the United States, men and women shake hands when they meet. Greetings are often casual such as a handshake, a smile and a “hello.” The British say
“hello” when they meet friends. They usually shake hands when they meet for the first time. Social kissing or a kiss on the cheek is common between men and
women and between women who know each other very well.
The Hebrew greeting is “shalom.” The French greeting is “bonjour.” The Spanish greeting in “hola” and the Zulu say “sawubona” when greeting friends.
In New Zealand people are often greeted by the Maori leaders with the traditional “Hongi” by rubbing noses.
When a younger person says hello to an older person in the Philippines, the younger person will bow and hold the right hand of the older person and press the
knuckles against their forehead. When the knuckles are touching the forehead they say “Mano”(means hand) and “Po”(means respect.)
In Japan the common greeting for men and women is to bow when they meet someone. The deeper the bow, the greater level of respect in shown.
In Arab countries, close male friends or colleagues hug and kiss both cheeks. They shake hands with the right hand only, longer but less firmly than in the
western world. Contact and hand shaking between men and women in public is considered rude.
Hungarians use the friendly greeting of kissing each other on the cheeks. The most common way to kiss is from your right to your left. When men meet for the
first time they give a firm handshake.
In Belgium people kiss on one cheek when they meet.
The Chinese when meeting someone for the first time usually nod their head and smile or shake hands if in a formal business situation.
In Russia a typical greeting is a very firm handshake while maintaining direct eye contact. When men shake hands with women, the handshake is less intense.
Men may also kiss a woman three times on alternating cheeks.
In Albania, men shake hands when greeting one another. Depending on how well the men know each other, a kiss on each cheek may be common as well. When a man
meets a female relative, a kiss on each cheek or two kisses per cheek is common. With friends or colleagues normally a light handshake is appropriate. Women
may shake hands or kiss each other on both cheeks.
In Armenia, a woman needs to wait for the man to offer his hand for the handshake. Between good friends and family members, a kiss on the cheek and a light
hug are also common.
Always remember you are a guest in another country. Please show respect for their customs and culture.
Decide whether the following statements are true (T) or false (F) according to the passage
1.In Britain, they usually kiss on the cheek between men and women when they first meet.
2.The Spanish greeting is “hola” and the Zulu say “sawubona” when greeting friends.
3.The common greeting for men and women is to bow to each other in both Philippines and Japan.
4.In Russia, a typical greeting is a very firm handshake without direct eye contact.
5.In Armenia, a woman needs to wait for the man to offer his hand for the handshake

Forty May Be the New 30 As Scientists Redefine Age Is 40 really the new 30？ In many ways people today act younger than their parents did at the same age.
Scientists have defined a new age concept and believe it could explain why populations are aging, but at the same time seem to be getting younger.
Instead of measuring aging by how long people have lived, the scientists have factored in how many more years people can probably still look forward to.
"Using that measure, the average person can get younger in the sense that he or she can have even more years to live as time goes on," said Warren Sanderson of the University of New York in Stony Brook.
He and Sergei Scherbov of the Vienna lnstitute of Demography (人口统计学) at the Austrian (奥地利的) Academy of Sciences, have used their method to estimate how the proportion of elderly people in Germany, Japan and the United States will change in the future.
The average German was 39.9 years old in 2000 and could plan to live for another 39.2 years, according to research reported in the journal Nature on Wednesday.
However, by 2050 the average German will be 51.9 years old and will be expected to live another 37.1 years. So middle age in 2050 would occur at around 52 years instead of 40 years as in 2000.
"As people have more and more years to live they have to save more and plan more and they effectively are behaving as if they were younger," said Sanderson.
Five years ago, the average American was 35.3 years old and could plan for 43.5 more years of life. By 2050, the researchers estimate it will increase to 41.7 years and 45.8 future years.
"A lot of our ski/Is, our education, our savings and the way we dear with our health care depend a great deal on how many years we have to live," said Sanderson.
This dimension of how many years people have to live has been completely ignored in the discussion of aging so far.
第36题：People 40 years of age today seem to be as young as
A．their parents were at the same age.
B．their parents were at the age of 30.
C．their children will be at the same age.
D．their children will be at the age of 30.

Oceanography has been defined as "The application of all sciences to the study of the sea". Before the nineteenth century, scientists with an interest in the sea were few and far between.
Certainly Newton considered some theoretical aspects of it in his writings, but he was reluctant to go to sea to further his work.
For most people the sea was remote, and with the exception of early intercontinental travelers or others who earned a living from the sea, there was little reason to ask many questions about it, let alone to ask what lay beneath the surface. The first time that the question "what is at the bottom of the oceans？" Had to be answered with any commercial consequence was when the laying of a telegraph cable from Europe to America was proposed. The engineers had to know the depth profile of the route to estimate the length of cable that had to be manufactured.
It was to Maury of the US Navy that the Atlantic Telegraph Company turned, in 1853, for information on this matter. In the 1840s, Maury had been responsible for encouraging voyages during which soundings were taken to investigate the depths of the North Atlantic and Pacific Oceans. Later, some of his findings aroused much popular interest in his book The Physical Geography of the Sea.
The cable was laid, but not until 1866 was the connection made permanent and reliable. At the early attempts, the cable failed and when it was taken out for repairs it was found to be covered in living growths, a fact which defied contemporary scientific opinion that there was no life in the deeper parts of the sea.
Within a few years oceanography was under way. In 1872 Thomson led a scientific expedition, which lasted four years and brought home thousands of samples from the sea.
Their classification and analysis occupied scientists for years and led to a fivevolume report, the last volume being published in 1895.
The proposal to lay a telegraph cable from Europe to America made oceanographic studies take on ______.
A．an academic aspect
B．a military aspect
C．a business aspect
D．an international aspect

Too much metal in the soil is considered pollution. Yet too little metal in a person's diet can cause health problems. An American scientist says the answer to both problems may be plants that take up large amounts of metal in their tissues.
David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals.
In recent years, scientists have shown interest in using such plants to clean up harmful waste materials. Professor Salt says such plants also could be used to improve people's diets or even to create foods that fight cancer.
Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is blamed for health problems in many developing countries. Children and pregnant women are mostly affected.
Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that contain minerals needed for good health.
For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants.
Locoweed, which is a common plant in the western U.S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil.
Many people take pills to add important minerals or vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form.
The scientist says his team would like to develop a vegetable crop high in selenium. He wants to create an anti-cancer product in the foods we already eat.
According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______.
A．clean polluted soil and cure disease like cancer
B．clean up harmful waste materials in soil and improve people's diet
C．produce large number of micronutrients such as iron and zinc
D．create food with important minerals or vitamins
