单项选择题Two major findings have emerged from these researches. Firstly, 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 aspects of the parent-child relationship. Much of the difference in measured intelligence between "privileged" and "disadvantaged" children may be due to the latter’s lack of appropriate verbal stimulation and the poverty of their perceptual experiences.

1.单项选择题In addition to his theory of color, Newton 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 theory 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 continued 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 followed 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 Newton’s ideas had delayed scientific progress for a hundred years.

2.单项选择题For years, U. S. automakers have fought tougher regulations by arguing that Americans tend to prefer larger, gas-guzzling SUVs and trucks. That’s not always true: when gas prices were at an all-time high last summer, sales of SUVs were down considerably, while hybrids flew off dealer lots. Since then, prices at the pump have dropped-and so has the appetite for small cars. As long as the price of gas remains volatile(易变的, 动荡不定的), it’s far from certain that Americans will buy the more efficient cars and trucks the new standards will require automakers to produce. In the long run, though, a gas tax that puts a floor on fuel prices may be the only way to break America’s SUV addiction. But Obama has said he’s not interested. "You need a price signal. Regulations alone won’t do it," says Lester Lave, director of the Carnegie Mellon Green Design Initiative.

A. gas prices hit new high last summer.
B. hybrids were out of stock last summer.
C. the government set limits on fuel price last summer.
D. the gas price remained fluctuing last summer.
