For a long time, researchers have tried to nail down just what shapes us--or what, at least, shapes us most. And over the years, they’ve had a lot of finding moments. First it was our parents, particularly our mothers. Then it was our genes. Next it was our peers, who show up last but hold great sway. And all those ideas were good ones--but only as far as they went.
The fact is once investigators had exposed all the data from those theories, they still came away with as many questions as answers. Somewhere, there was a sort of temperamental dark matter exerting an invisible gravitational pull of its own. More and more, scientists are concluding that this un explained force is our siblings.
From the time they are born, our brothers and sisters are our collaborators and coconspirators, our role models and cautionary tales. They are our scolds, protectors, goads, tormentors, playmates, counselors, sources of envy, objects of pride. They te
A. Previous findings revealed what shapes us.
B. Previous findings were accurate and trustworthy.
C. Previous findings contributed in a limited way.
D. Previous findings went too far in explanation.

We have known for a long time that the organization of any particular society is influenced by the definition of the sexes and the distinction drawn between them. But we have realized only recently that the identity of each sex is not so easy to pin down, and that definitions evolve in accordance with different types of culture known to us, that is, scientific discoveries and ideological revolutions. Our nature is not considered as immutable, either socially or biologically. As we approach the beginning of the 21st century, the substantial progress made in biology and genetics is radically challenging the roles, responsibilities and specific characteristics attributed to each sex, and yet, scarcely twenty years ago, these were thought to be "beyond dispute".
We can safely say, with a few minor exceptions, that the definition of the sexes and their respective functions remained unchanged in the West from the beginning of the 19th century to
A. there is almost no clue to the identity of both sexes.
B. the role distinction between different sexes is conspicuous.
C. the different definitions of sexes bears on the development of culture.
D. the progress of civilization greatly influences the role definitions of sexes.

Scientists have long warned that some level of global warming is a done deal—due in large part to heat-trapping greenhouse gases humans already have pumped skyward. Now, however, researchers are fleshing out how much future warming and sea-level rise the world has triggered. The implicit message: "We can’t stop this, so how do we live with it" says Thomas Wigley, a climate researcher at NCAR.
One group, led by Gerald Meehl at NCAR, used two state-of-the-art climate models to explore what could happen if the world had held atmospheric concentrations of greenhouse gases steady since 2000. The results: Even if the world had slammed on the brakes five years ago, global average temperatures would rise by about 1 degree Fahrenheit by the end of the 21st century. Sea levels would rise by another 4 inches over 20th-century increases. Rising sea-levels would continue well beyond 2100, even without adding water from melting glaciers and i
A. call on people to prevent global warming.
B. present the results from two research models.
C. appeal to people to take adaptation as priority.
D. forecast the future trends of global warming.
