Crying and waking up in the middle of night are routine during any newborns first few mont

hs. But if those crying episodes continue on a regular【C1】______past the first year, then they may signal possible behavioral problems【C2】______. Thats what researchers in Europe found when they【C3】______nearly two dozen studies on something developmental experts call regulatory problems—which include trouble sleeping, continuous crying and difficulty feeding. The researchers【C4】______in the journal Archives of Disease in Childhood that infants who consistently cry and wake up at night past their third month are nearly twice as likely to【C5】______problems such as attention deficit hyperactivity disorder (ADHD), depression, anxiety, aggressive behavior. or【C6】______disorders by the time they begin school. The most【C7】______behavioral difficulties these children had involved【C8】______of self-control, and an inability to calm themselves down or act【C9】______in different social situations. How exactly are【C10】______crying jags and picky eating during infancy【C11】______later behavioral problems？ Dieter Wolke, one of the study co-authors and a professor of developmental psychology at University of Warwick in England, says the data dont support any【C12】______link, but there are several possibilities. One, the crying and waking up at night are simply the first signs of behavioral problems that the babies can not【C13】______themselves very well. Every baby wakes up several times a night and may start crying, but most will eventually learn to calm themselves down and【C14】______back to sleep. They learn that enough is e-nough and inevitably【C15】______that Mom and Dad wont come running every time they cry. If babies are already【C16】______to contracting a behavioral disorder, 【C17】______, they may not be able to learn such self-control, and their crying episodes may continue well past their first year. 【C18】______, says Wolke, some infants may be genetically susceptible to problems regulating their behavior; specifically, scientists have recently identified a version of a【C19】______concerning dopamine function, which governs mood and emotions as well as motor function, that may make some infants more【C20】______to behavioral problems.

第4题

Material culture refers to the touchable, material "things"—physical objects that can be s

een, held, fell, used — that a culture produces. Examining a culture's tools and technology can tell us about the group's history and way of life. Similarly, research into the material culture of music: can help us to understand the music culture. The most vivid body of "things" in it, of course, are musical instruments. We cannot bear for ourselves the actual sound of any musical performance before the 1870s when phonograph was invented, so we rely on instruments for important information about music-cultures in the remote past and their develop ment. Here we have two kinds of evidence: instruments well preserved and instruments pictured in art. Through the study of instruments, as well as paintings, written documents, and so on, we can explore the movement of music from the Near East to China over a thousand years ago, or we can outline the spread of Near Eastern influence to Europe that resulted in the development of most of the instruments in the symphony orchestra.

Sheet music or printed music, too, is material culture. Scholars once defined folk music-cultures as those in which people learn and sing music by ear rather than from print, but research shows mutusl influence

among oral and written sources during the past few centuries in Europe, Britain, and America. Printed versions limit variety because they tend to standardize any song, yet they stimulate people to create new and different songs. Besides, the ability to read music notation has a far-reaching effect on musicians and, when it becomes widespread, on the music cul Lure as a whole.

One more important part of music's material culture should be singled out: the influence of the electronic media—radio, record player, tape recorder, television, and videocassette, with the future promising talking and singing computers and other developments. This is all part of the "information revolution", a twentieth-century phenomenon as important as the industrial revolution was in the nineteenth. These electronic media are not just limited to modern nations; the)' have affected music cultures all over the globe.

Research into the material culture of a nation is of great importance bucause ______.

A．it helps produce new cultural tools and technology

B．it can reflect the development of the nation

C．it helps understand the nation's past and present

D．it can demonstrate the nations civilization

第6题

Scattered around the globe are more than 100 small regions of isolated volcanic activity k

nown to geologists as hot spots, unlike most of the world's volcanoes, they are not always found at the boundaries of the great drifting plates that make up the earth's surface; on the contrary, many of them lie deep in the interior of a plate. Most of the hot spots move only slowly, and in some cases the movement of the plates past them has left trails of dead volcanoes. The hot spots and their volcanic trails are milestones that mark the passage of the plates.

That the plates are moving is now beyond dispute. Africa and South America, for example, are moving away from each other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth's interior. It is not possible to determine whether both continents are moving in opposite directions or whether one continent is stationary and the other is drifting away from it. Hot spots, anchored in the deeper layers of the earth, provide the measuring instruments needed to resolve the question. From an analysis of the hot spot population it appears that the African plate is stationary and that it has not moved during the past 30 mil lion years.

The significance of hot spots is not confined to their role as a frame. of reference. It now appears that they also have an important influence on the geophysical processes that propel the plates across the globe. When a continental plate comes to rest over a hot spot, the material rising from deeper layer creates a broad dome. As the dome grows, it develops deed fissures (cracks); in at least a few cases the continent may break entirely along some of these fissures, so that the hot spot initiates the formation of a new ocean. Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability (inconstancy).

The author believes that ______.

A．the motion of the plates corresponds to that of the earth's interior

B．the geological theory about drifting plates has been proved to be truse

C．the hot spots and the plates move slowly in opposite directions

D．the movement of hot spots proves the continents are moving apart

1：第一篇Reading Comprehension: When global warming finally came, it stuck with a vengeanc

e. In some regions, temperatures rose several degrees in less than a century. Sea levels shot up nearly 400 feet, flooding coastal settlements and forcing people to migrate inland. Deserts spread throughout the world as vegetation shifted drastically in North America, Europe and Asia. After driving many of the animals around them to near extinction, people were forced to abandon their old way of life for a radically new survival strategy that resulted in widespread starvation and disease. The adaptation was farming: the global-warming crisis that gave rise to it happened more than 10,000 years ago. As environmentalists convene in Rio de Janeiro this week to ponder the global climate of the future, earth scientists are in the midst of a revolution in understanding how climate has changed in the past—and how those changes have transformed human existence. Researchers have begun to piece together an illuminating picture of the powerful geological and astronomical forces that have combined to change the planet's environment from hot to cold, wet to dry and back again over a time period stretching back hundreds of millions of years. Most important, scientists are beginning to realize that the climatic changes have had a major impact on the evolution of the human species. New research now suggests that climate shifts have played a key role in nearly every significant turning point in human evolution: from the dawn of primates some 65 million years ago to human ancestors rising up to walk on two legs, from the huge expansion of the human brain to the rise of agriculture. Indeed, the human history has not been merely touched by global climate change, some scientists argue, it has in some instances been driven by it. The new research has profound implications for the environmental summit in Rio. Among other things, the findings demonstrate that dramatic climate change is nothing new for planet Earth. The benign global environment that has existed over the past 10,000 years—during which agriculture, writing, cities and most other features of civilization appeared—is a mere bright spot in a much larger pattern of widely varying climate over the ages. In fact, the pattern of climate change in the past reveals that Earth's climate will almost certainly go through dramatic changes in the future—even without the influence of human activity, 1.The message the author wishes to convey in the passage is that ______.

A.human civilization remains gorious though it is affected by climatic changes

B.mankind is virtually helpless in the face of the dramatic changes of climate

C.man has to limit his activities to slow down the global warming process

D.human civilization will continue to develop in spite of the changes of nature
