Scientists used to explore on the surface of the ocean. Now they are exploring below the surface, too. They want to know about ocean water and the plant and animal life deep in the ocean.
In 1934 the scientist William Beebe dived 3,000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10, 330 feet. In 1960 his son Jean dived to a depth of 35,800 feet.
All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below the surface. Gradually they succeeded. Cousteau, a Frenchman, was able to keep men down to a depth of 36 feet for one month and to a depth of 90 feet for a week.
Now scientists are developing even better equipment. With this new equipment, men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then in 1964 he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate without help from the surface.
Many countries are now studying undersea living things. The former Soviet Union had an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the entire world.
64. In order to _____, scientists are exploring below the surface of the ocean.
A. know about the ocean water deep in the ocean
B. know about the plant and animal life deep in the ocean
C. stay down longer to study life of the plant and animal below the surface
D. both A and B
65. Who set up the first undersea station?
A. A Frenchman B. An American
C. A Russian D. The passage made no mention
66. Which of the following is true according to the passage?
A. Nobody can stay below the surface of the ocean.
B. The early divers could not stay below the surface of the ocean for very long.
C. The purpose of setting up the undersea laboratories is to make plans for the use of the resources in the ocean.
D. Up to now only five women scientists have stayed in the undersea laboratory.

While all my classmates seen to be crazy about a one-way ticket to Mars(火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anybody explain to me just why people would go to Mars, never to return?
Steve Minear, UK
Here are the things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements.
Donal Trollop, Canada
There are already too many people on the Earth. I think that sometime before the end of the century, there will be a human colony(殖民地)on Mars. It will happen when people finally realize that tow-way trips to the red planet Mars are unnecessary. Most of the danger of space Flight is in the launches(发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement on another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies. USA
The main purpose of Steve Minear’s writing is .
A. to report his classmates’ discussion B. to invite an answer to his question

Paul Davies points out that .
A. humans need only a one-way ticket to Mars.
B. two-way trips to Mars will be made safe soon
C. it is easy to reduce the danger and cost of flights to Mars
D. it is cheap to build an everlasting human settlement on Mars
What does Paul Davies think of human existence on Mars?

A “lost tribe” that reached America from Australia may have been the first Native Americans, according to a new theory.
If proved by DNA evidence, the theory will break long established beliefs about the southerly migration of people who entered America across the Bering Strait, found it empty and occupied it.
On this theory rests the belief of Native Americans to have been the first true Americans. They would be classified to the ranks of escapee, beaten to the New World by Aboriginals (土著人) in boats.
To a European, this may seem like an academic argument, but to Americans it is a philosophical question about identity, Silvia Gonzales, of Liverpool University said .
Her claims are based on skeletons found in the California Peninsula of Mexico that have skulls quite unlike the broad Mongolian features of Native Americans. These narrow-skulled people have more in common with southern Asians, Aboriginal Australians and people of the South Pacific Region.
The bones, stored at the National Museum of Anthropology (人类学) in Mexico City, have been carbon-dated and one is 12,700 years old, which places it several thousand years before the arrival of people from the North. “We think there were several migration waves into the Americas at different times by different human groups,” Dr. Gonzales said. “The timing, route and point of origin of the first colonization of the Americas remains a most contentious topic in human evolution.”
But comparisons based on skull shape are not considered conclusive by anthropologists, so a team of Mexican and British scientists, backed by the Natural Environment Research Council, has also attempted to take out DNA from the bones. Dr. Gonzales declined yesterday to say exactly what the results were, as they need to be checked, but indicated that they were consistent(一致) with an Australian origin.
It is generally considered that the first Native Americans came from ________.
A. North Asia B. Australia
C. South Pacific D. South Asia
The skeletons found in the California Peninsula of Mexico have ________.
A. the broad skull shape
B. the narrow skull shape
C. different features of Aboriginal Australians
D. the same features of Native Americans
The underlined “contentious” is similar in meaning to “________”.
A. likely to cause great interest B. difficult to solve
C. well-known to all D. likely to cause argument
Which of the following statements is true according to the text?
A. Research on skulls can draw an exact conclusion.
B. DNA tests have proved the fact that the first Native Americans came from Australian.
C. Scientists are still not sure about the origin of the Native Americans.
D. People began to enter America across the Bering Strait about 12,700 years ago.

Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses (感觉)—smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over and over again. These repeated（重复的） dreams are often unpleasant. They may even be nightmares—bad dreams that frighten us.
Early in the twentieth century, two famous scientists developed their personal ideas about dreams. Austrian psychiatrist(心里学家) Sigmund Freud published a book called “The Interpretation(诠释) of Dreams” in 1900. Freud believed people often dream about things they want but can’t have. These dreams often have something to do with sex and aggression(侵犯). Swiss psychiatrist Carl Jung worked closely with Freud for several years, but he believed dreams could help people grow and understand themselves. He believed dreams provide solutions(解答) to problems we face when we are awake. He didn’t believe dreams hide our feelings about sex or aggression. Today we know more about the science of dreaming because researchers can take pictures of people’s brains while they are sleeping.
Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions(感情). Robert Stickgold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stickgold says that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud that dreaming is the way we express our hidden feelings and desires(愿望).
Scientists believe it is important to keep researching dreams. Doctor Stickgold says it has been more than one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.
Dreams _________.
A. are remembered by everyone
B. express all that we think in our mind
C. include few senses and things we touch
D. are sometimes nightmares(恶梦) that repeat and frighten us
A book on dreaming was published by _________.
A. Sigmund Freud B. Robert Stickgold C. Carl Jung D. the writer
In the passage, all the psychiatrists _________.
A. believe dreams can help people understand all the problems that they face
B. think dreams always hide someone’s feelings about sex or aggression
C. study dream and dreaming and have their own ideas
D. have the same idea that people often dream about the things they want
From the passage, we know that _________.
A. Jung thought that dreams provide solutions to problems we face when we are sleeping
B. Freud developed the idea that dreams are expressions of people’s hidden feelings
C. scientists have known quite well why we dream because they can take pictures of our brains
D. other researchers have discovered how dreaming helps our bodies work with problems and very sad emotions
Which would be the best title(标题) for the passage?
A. The Explanations of Dreams B. The Ways of Dreams
C. The Solutions to Dreams D. The Mystery(奥秘) of Dreams and Dreaming

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy (银河星系), scientists find that 5% are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution (进化) of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.
However, many scientists wonder whether intelligent (智能的) life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
According to the passage, how many planets in our galaxy might be inhabitable?
A. 5 billion． B. 10 billion. C. 15 billion. D. 200 billion
The first paragraph in this passage is mainly about ________ .
A. how scientists are looking for signs of life on other planets
B. why scientists are looking for signs of life on other planets
C. where scientists are looking for signs of life on other planets
D. when scientists are looking for signs of life on other planets
Which of these statements is True based on the information in the passage?
A. The earth is one of the oldest planets in our galaxy.
B. Most scientists believe that there is intelligent life on other planets.
C. Scientists don’t believe that there might be life on other planets.
D. Scientists are trying different ways to find signs of life on other planets.
