That is just one of the newer gimmicks that make the modem car so much more comfortable to drive than those produced not so long ago. Another innovation is the self-adjusting seat. When you put the key in the car door, the front seat will automatically adjust itself to the driver's preferred driving position.
These ideas were dreamt up at General Motors' research laboratories in Detroit. The laboratory was set up in the mid-sixties, in response to consumer groups who attacked the company for its safety record. Since then, the company has set itself an impossible goal: that you'll be able to walk away from most car accidents. It spends roughly one billion US dollars every year on safety research.
The company is working on helping drivers survive crashes at higher speeds. The idea is that the driver won't fly out of the car because of his seat belt, He won't be crushed by the side door coming in because it will be strengthened by a side beam. His ribs won't be crushed, nor his organs injured by the steering wheel, because it will bend when the body hits it. His face won't be slashed by broken glass because the windscreen won't shatter.
Every year, the total world-wide bill for injuries of all types is estimated at US $ 500 billion. Transport injuries of all sorts account for one quarter of this. This gives some indication of the size of the problem the scientists working at General Motors' research laboratory have set themselves.
"Not any more." in paragraph one indicates that ______.
A．the sun is no longer as hot these days
B．the car's air-conditioner can make the interior cooler
C．the painful experience doesn't exist any longer
D．the driver doesn't need to wait before he gets in the ear now

听力原文：M: How did you like yesterday's astronomy class？
W: It was interesting. But the point she was trying to make seemed a little far-fetched.
M: Oh, that new theory that ocean water came from comets？
W: Yeah. Do you remember what it was based on'？
M: Some recent satellite photos, I think. Apparently, Space satellites recently detected thousands of small comets colliding with earth's outer atmosphere, almost 40,000 per day.
W: OK, they're collided with atmosphere. So that's what created the water？
M: It's not the collision that created water. Comets contain water. They're made up mostly of cosmic dust and water. When they collide with the atmosphere, they break up. And the water they contain rains down to earth. Ocean water came from that rain.
W: Oh well, this morning I asked my geology professor about that. He said that most geologists don't accept it.
M: Why not？
W: Special research indicates that most of the water molecules from the comet would have burned up as they fell through the atmosphere. Enough rain couldn't have reached the earth to fill up the ocean.
M: Well, did the geologists have an alternative theory to explain where ocean water came from？
W: Yeah, he said the more traditional view is that the ocean water came from volcanoes.
M: From volcanoes？
W: Right. They say volcanic fumes are mostly steam. And they claimed that it was the volcanic steam that created the oceans, not rain from comets.
(20)
A．The effect of the atmosphere on rainfall.
B．How conditions on earth support life.
C．How water originated on earth.
D．A new estimate of the age of earth.

Leeds University researchers, writing in the Psychopathology journal, said a small proportion of Internet users were classed as Internet addicts and that people in this group were more likely to be depressed than non-addicted users.
The article on the relationship between excessive Internet use and depression, a questionnaire-based study of 1,319 young people and adults, used data gathered from respondents to links placed on UK-based social networking sites.
The respondents answered questions about how much time they spent on the Internet and what they used it for; they also completed the Beck Depression Inventory--a series of questions designed to measure the severity of depression.
The six-page report, by the university's Institute of Psychological Sciences, said 18 of the people who completed the questionnaire were Internet addicts.
"Our research indicates that excessive Internet use is associated with depression, but what we don't know is which comes flint--are depressed people drawn to the Internet or does the Internet cause depression？" the article's lead author, Dr.Catriona Morrison, said. "What is clear is that, for a small part of people, excessive use of the Internet could be a warning signal for depressive tendencies."
The age range of all respondents was between 16 and 51 years, with a mean age of 21.24. The mean age of the 18 Internet addicts, 13 of whom were male and five female, was 18.3 years. By comparing the scale of depression within this group to that within a group of 18 non-addicted Internet users, researchers found the Internet addicts had a higher incidence of moderate to severe depression than non-addicts. They also discovered that addicts spent proportionately more time browsing sexually pleasing websites, online gaming sites and online communities.
"This study reinforces the public speculation (推测) that over-engaging in websites that serve to replace normal social function might be linked to psychological disorders like depression and addiction," Morrison said. "We now need to consider the wider societal implications of this relationship and establish clearly the effects of excessive Internet use on mental health."
Internet addicts are people who______.
A．use the Internet more than enough
B．feel depressed when using the Internet
C．seldom connect to the Internet
D．feel depressed without the Internet

Some brains do deteriorate with age. Alzheimer's disease, for example, strikes 13 percent of Americans 65 and older. But for most aging adults, the authors say, much of what occurs is a gradually widening focus of attention that makes it more difficult to latch onto just one fact, like a name or a telephone number. Although that can be frustrating, it is often useful. "It may be that distractibility is not, in fact, a bad thing," said Shelley H. Carson, a psychology researcher at Harvard whose work was cited in the book. "It may increase the amount of information available to the conscious mind. "
For example, in studies where subjects are asked to read passages that are interrupted with unexpected words or phrases, adults 60 and older work much more slowly than college students. Although the students plow through the texts at a consistent speed regardless of what the out-of-place words mean, older people slow down even more when the words are related to the topic at hand. That indicates that they are not just stumbling over the extra information, but are taking it in and processing it. When both groups were later asked questions for which the out-of-place words might be answers, the older adults responded much better than the students.
"For the young people, it's as if the distraction never happened," said an author of the review, Lynn Hasher, a professor of psychology at the University of Toronto and a senior scientist at the Rotman Research Institute. "But for older adults, because they've retained all this extra data, they' re now suddenly the better problem solvers. They can transfer the information they've soaked up from one situation to another. "
Such tendencies can yield big advantages in the real world, where it is not always clear what information is important, or will become important. A seemingly irrelevant point or suggestion in a memo can take on new meaning if the original plan changes. Or extra details that stole your attention, like others'yawning and fidgeting, may help you assess the speaker's real impact.
From the first two paragraphs, we learn that______.
A．aging brains tend to process more information simultaneously
B．one becomes forgetful when he gets old
C．older people don't think their brainpower is declining
D．the aged always stress long-term benefit
