S. automakers have fought tougher regulations by arguing that Americans tend to prefer larger, gas-guzzling SUVs and truc

13、y, the greater part of the development of observed intelligence occurs in the earliest years of life. It is estimated that 50 percent of measurable intelligence at age 17 is already predictable by the age of four. Secondly, the most important factors in the environment are language and psychological

14、 aspects of the parent-child relationship. Much of the difference in measured intelligence between “privileged“ and “disadvantaged“ children may be due to the latters lack of appropriate verbal stimulation and the poverty of their perceptual experiences.The paragraph mainly talks about A. observed i

This is. the process that underlies learning: every change in the junctions be

17、tween brain cells signifies a new fact or skill thats been picked up and stowed away for future use. BDNF makes that process possible. Brains with more of it have a greater capacity for knowledge. On the other hand, says UCLA neuroscientist Fernando Gmez-Pinilla, a brain thats low on BDNF shuts itse

21、developed a theory of how light travels. This is known as the corpuscular theory of light, meaning that light travels as a series of tiny bits rather than in continuing waves. Newton sent his writings to the Royal Society where they were given to a committee led by Hooke. Since the corpuscular theor

22、y was different from his own theory, Hooke attacked the paper. Soon others started to argue, and Hooke was supported by a scientist from Holland, Chritain Huygens. At one time, Newton was so unhappy with the whole affair that he decided never again to publish any of his work.The bitter argument cont

23、inued over the years that followed. At first, Hooke and Huygens received most of the support. Later, after Newton had changed his mind and let his work on gravity be published, he became so famous that things changed. Now people believed Newton could do nothing wrong, and for a hundred years they fo

24、llowed his theory. Then, in the early part of the 19th century, the experiments of a French scientist, Augustin Fresnel, showed that light could be explained best by a wave theory. So the scientists changed sides again, saying that Newtons ideas had delayed scientific progress for a hundred years.Ne

Therefore, they are continually discontented. By their remarks, they sour the pleasure of the society, offend

30、 many people, and make themselves disagreeable everywhere. If this turn of mind were founded in nature, such unhappy persons would be the more to be pities.

Rink is hoping that his merchandise appeals to budget-strapped municipalities. “Co

34、mpared with building new storm-water treatment plants or upgrading already existing facilities to handle runoff pollution, which would cost in the millions of dollars, our products are very affordable,“ he says.

A recent study from the University of Lbeck, in Germany, offers one clue. Subjects were given a list of 46 word

36、 pairs to memorize, just before sleep. Then when they reached the deepest stages of sleep, electrical currents were sent through electrodes on their heads to induce very slow brain waves. Such slow waves were induced at random in the brains of one group of subjects, but not another.The next morning,

37、 the slow-wave group had better recall of the words. Other types of memory were not improved, and inducing the slow waves later in the night did not have the same effect. Why and how the slow waves improved memory is not yet understood, but they are thought to alter the strengths of chemical connect

38、ions, or synapses, between specific pairs of nerve cells in the brain. Memories are “stored“ in these synapses: changing the strength of the synapses increases the strength of the memories they store.Slow waves functioned in the subjects brains in the experiment when A. they were given a list of wor

The model preferred by

43、the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers.The researchers argue that the level of radiation-induced cancers is “not very significant“ compared to the far larger number of cancers that are discovered and treated. The Valencia programme, they sa
