People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we"re looking at science fiction becoming tomorrow"s reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are" making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don"t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer．
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

In college, music education is one of the largest programs．Teachers have to learn general education materials and techniques． They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more．At the same time, much of our culture and tradition is absorbed in music．
Music plays a very important role in our education．
Music helps with math and science． Students learn to count, and how to multiply and divide．Students also use science to help them discover what sounds good together and what doesn"t．Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（颤动）and why．
Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones．Students must learn to translate these works to understand what they are singing about． A song is likely to be a famous short work set to music; so students are exposed to that very often while singing．
Students learn a huge amount of cooperation （协作）of body parts through music, so parts of the body can work better together．Students must use motor（肌肉运动的）skills in order to play an instrument．Singers and wind（管乐器）players must learn breath control and be in good shape to play．
Students learn about art． Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they"re playing the music．
Music education also brings higher thinking to our children．It allows them to think about complex patterns．Students have to be aware of what every other musician does at every time．In that way, it develops cooperation, as well．They tend to develop more ability for learning．
As one can see, music is very important to education．

Researchers at Harvard University, however, have found that there’s one thing musical training does not do. Samuel Mehr, the leading researcher of the new study, said it is wrong to think that learning to play a musical instrument improves a child’s intellectual development. The evidence comes from studies that measured the mental ability of two groups of 4-year-olds and their parents. One group attended music class; the comparison group went to a class that places importance on the optical arts-arts that can be seen.
“We found no evidence for any advantage on any of these tests for the kids participating in these music classes,” said Mehr.
Samuel Mehr says researchers have carried out many studies in an effort to learn whether musical training can make children smarter. Only one study seems to show a small percentage increase in IQ, intellectual scores among students after one year of music lessons.
He does not believe that IQ is a good measure of a child’s intelligence. Therefore, the researchers in his study compared how well children in the musical training group did on mental processing tasks, then the results were compared to those of children who did not take lessons.
Music lessons may not offer children a fast easy way to gain entry to the best schools later of their life, but the training is still important.
Mr Mehr notes that the works of writer William Shakespeare are not taught , so the children will do better in physics. He says Shakespeare is taught because it is important for cultural reasons.“And I don’t think music needs to be any different than that.”
小题1:What attitude do most American grown-ups have towards music lessons? _________
| A．Uninterested | B．Approving | C．Doubtful | D．Uncertain |
| A．visual | B．colorful | C．traditional | D．serious |
| A．many studies show that music training can improve IQ |
| B．IQ is a good measure of a child’s intelligence |
| C．music can enable a child to go to a better school |
| D．music should be taught for cultural reasons |
| A．early music training has negative effects |
| B．musical lessons should be stopped at school |
| C．musical training doesn’t improve kids’ intelligence |
| D．playing musical instrument makes kids more creative |
Norwegian researchers now report that it’s a matter of what they call social rank in the family that gives the first born the highest scores or, if the first born had died young, the next oldest.
Kristensen and Bjerkedal studied the IQ test results of 241,310 Norwegian men drafted(征兵) into the armed forces between 1967 and 1976. All were aged 18 or 19 at the time.
The average IQ of first-born men was 103.2, they found second-born men averaged 101.2, but second-born men whose older brother died young scored 102.9. And for third-borns, the average was 100.0. But if both older brothers died young，the third-born score rose to 102.6.
The findings provide “evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such.” they concluded.
It’s an issue that has been hotly discussed since at least 1874,when Sir Francis Galton reported that men in noticeable positions tended to be firstborns more often than would have been statistically (统计) expected.
Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports.
“These two researchers prove that how study participants(参与者) were raised, not how they were born, is what actually influences their IQs,” said Sulloway, an American professor, who was not part of the research team.
“The elder child pulls ahead,” he said, “perhaps as a result of learning gained through the process of tutoring younger brothers and sisters”.
“The older child benefits by having to organize and express its thoughts to tutor youngsters”, he said, “while the later born children may have no one to tutor.”
小题1:According to Norwegain researchers’ finding, which of the following is linked to boys’ IQ?
| A．Birth order | B．Position in the family |
| C．Parents’ social rank | D．Educational experience |
| A．Many people take interest in IQ study. |
| B．IQ study has gone further and further. |
| C．Many people do research on boys’ IQ. |
| D．Opinions are divided on the conclusion. |
| A．treating them as the oldest child |
| B．teaching them as the oldest child |
| C．talking to them as much as possible |
| D．encouraging them to express thoughts |
