Scientists have found that although we are prone to snap overreactions, if we take a moment and think about how we are likely to react, we can reduce or even eliminate the negative effects of our quick, hard-wired responses.
Snap decisions can be important defense mechanisms; if we are judging whether someone is dangerous, our brains and bodies are hard-wired to react very quickly, within milliseconds. But we need more time to assess other factors. To accurately tell whether someone is sociable, studies show, we need at least a minute, preferably five. It takes a while to judge complex aspects of personality, like neuroticism or open-mindedness.
But snap decisions in reaction to rapid stimuli aren’t exclusive to the interpersonal realm. Psychologists at the University of Toronto found that viewing a fast-food logo for just a few milliseconds primes us to read 20 percent faster, even though reading has little to do with eating. We unconsciously associate fast food
A. vary according to the urgency of the situation
B. prove the complexity of our brain reaction
C. depend on the importance of the assessment
D. predetermine the accuracy of our judgment

We have a crisis on our hands. You mean global warming The world economy No, the decline of reading. People are just not doing it anymore, especially the young. Who’s responsible Actually, it’s more like, What is responsible The Internet, of course, and everything that comes with it--Facebook, Twitter(微博). You can write your own list.
There’s been a warning about the imminent death of literate civilization for a long time. In the 20th century, first it was the movies, then radio, then television that seemed to spell doom for the written world. None did. Reading survived; in fact it not only survived, it has flourished. The world is more literate than ever before--there are more and more readers, and more and more books.
The fact that we often get our reading material online today is not something we should worry over. The electronic and digital revolution of the last two decades has arguably shown the way forward for reading and for writing. Take the arrival of e-book rea
A. Paragraph One.
B. Paragraph Two.

In recent years scientists have found that the laser has a wide variety of applications, making it one of the most important inventions for improving our quality of life.
One important field in which the laser has many applications is communications. Scientists have found that the laser beam can transmit human voices; as a result, telephone companies are now using laser light signals to transmit telephone calls through extremely small cables that are capable of carrying many more transmissions than the standard telephone cables. An additional advantage is that these systems using the laser light signals are also able to transmit video telephone conversations.
Another, perhaps less-known, field in which lasers are helping improve the quality of life is metrology—the science of measurement. The extremely straight, narrow laser beam can be used to put the parts of a structure being built into the correct position to each other
A. medical treatment
B. national defense
C. space travel
D. metrology
