[单项选择]New forms of media have always caused moral panics: the printing press, newspapers, and television were all once denounced as threats to their consumers’ brainpower and moral fiber. So too with electronic technologies. PowerPoint, we’re told, is reducing speech to bullet points. Search engines lower our intelligence, encouraging us to skim on the surface of knowledge rather than dive to its depths. Twitter is shrinking our attention spans.
But such panics often fail basic reality checks. When comic books were accused of turning juveniles (少年) into delinquents (有违法倾向) in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline. The decades of television, radios and rock videos were also decades in which I. Q. scores rose continuously.
For a reality check today, take the state of science, which demands high levels of brainwork and is measured by clear standards of discovery. These days sci
A. drive people insane
B. make people impatient
C. threaten people’s brainpower
D. improve people’s attention span
[填空题]When a new vent forms, tube worms congregate around it voluntarily.
[单项选择]Technological development has historically been a powerful driver of globalization, especially over the past two centuries. In agriculture, in particular, technical change underpinned the industrial revolution, improvements in nutrition, and a surge in world population. Interactions between population increases and technical changes in agriculture and industry, mostly since the nineteenth century, converged to expand trade and flows of finance and labor. These have been the essence of globalization.
The integration of the world economy would have been impossible without the technological developments in agriculture that proved wrong predictions of the inevitability of world famine. Technology further supported significant improvements in world food production and food security. Although substantial numbers of people are still food insecure, this is due not to lack of overall production but is related to the location of production, income levels, and access to food by countries, ho
A. the world’s overall food demand still exceeds food supply.
B. technical changes have not produced enough food.
C. many of the people do not have the money to buy it.
D. population increases have outpaced food production.

Historically, the European Union has not bothered with funding much basic scientific research. Such activities have mainly remained the preserve of national governments, not least because giving scientists free rein can lead to discoveries that not only make money but ultimately enhance military might.
That attitude is now changing. The European Commission proposes to establish a European Research Council (ERC) that would spend a maximum of 12 billion ( $14 billion) over seven years on" blue skies" research. While the plans are being generally welcomed by Europe’s member states, their details are problematic. The proposed ERC is intended to make Europe more competitive. Europe has some first-class universities, scientific institutions and research organisations. But, the ERC’s proponents argue, their activities are fragmented, so they are not reaching their full potential.
In America, teams from acros
A. the European Union is not as competitive as the U. S
B. member states cannot cooperate as should have
C. Europe does not have enough top research institutions
D. research activities in Europe lack enough competition

Historically, humans get serious about avoiding disasters only after one has just struck them. (21) that logic, 2006 should have been a breakthrough year for rational behavior. With the memory of 9/11 still (22) in their minds, Americans watched hurricane Katrina, the most expensive disaster in U.S. history, on (23) TV. Anyone who didn’t know it before should have learned that bad things can happen. And they are made (24) worse by our willful blindness to risk as much as our (25) to work together before everything goes to hell.
Granted, some amount of delusion (错觉) is probably part of the (26) condition. In A.D. 63, Pompeii was seriously damaged by an earthquake, and the locals immediately went to work (27) , in the same spot—until they were buried altogether by a volcano eruption 16 years later. But a (28) of the past year in disaster history suggests that modern Americans are particularly
