A new scheme for getting children to and from school is being started by the education authorities in part of Eastern England． This could end the worries of many parents fearful for their children's safety on the roads．
Until now the Country Council has only been prepared to provide bus services for children living more than three miles from their school, or sometimes less if special reasons existed． Now it has been decided that if a group of parents ask for help in organizing transport they will be prepared to go ahead, provided the arrangement will not lose money and that children taking part will be attending their nearest school．
The new scheme is to be tried out this term for children living at Milton who attend Impington school． The children live just within the three-mile limit and the Council has said in the past it will not undertake to provide free transport to the school． But now they have agreed to organize a bus service from Milton to Impington and back, a plan which has the support of the school's headmaster．
Between 50 and 60 parents have said they would like their children to take part in． Final calculations have still to be carried out, but a council official has said the cost of parents should be less than $6．50 a tenn．
They have been able to arrange the service at a low cost because there is already an agreement with the bus company for a bus to take children who live further away to Impington． The same bus would now just make an extra journey to pick up the Milton children． The official said they would get in touch with other groups of parents who in the past had asked if transport could be provided for their children, to see if they would like to take part in the new scheme．
The children the Council ran buses for in the past were those__________．A.whose parents were worried about them
B.who would have had to walk otherwise
C.who could not walk
D.who had to travel a long way

The Bilingual BrainWhen Karl Kim immigrated to the United States from Korea as a teenager,he had a hard time learning English.Now he speaks it fluently, and he had a unique opportunity to see how our brains adapt to a second language.As a graduate student, Kim worked in the lab of Joy Hirsch, a neuroscientist in New York Their work led to an important discovery.They found evidence that children and adults don't use the same parts ofthe brain when they learn a second language.The researchers used an instrument called an MRI(magnetic resonance imaging)scanner to study the brains of two groups of bilingual people.One group consisted of those who had learned a second language as children.The other consisted of people who,like Kim,learned their second language later in lite.Peoplefrom both groups were placed inside the MRI scanner ,This allowed Kim and Hirsch to see which parts of thebrain were getting more blood and were more active.They asked people from both groups to think about whatthey had done the day before ,first in one language and then the other.They couldn't speak out loudbecause any movement would disrupt（干扰）the scanning.Kim and Hirsch looked specifically at two language centers in the brain-Broca' s area, which isbelieved to control speech production,and Wernicke's area,which is thought to process meaning.Kim andHirsch found that both groups of people used the same part of Wernicke's area no matter what language theywere speaking.But their use of Broca's area was different.People who learned a second language as children used the same region in Broca's area for both tneir first and second languages.People who learned a second language later in life used a different part of Broca's area for their second language.How does Hirsch explain this difference?Hirsch believes that when language is first being programmed in young children,their brains may mix the sounds and structures of all languages in the same area.Once that programming is complete,the processing of a new language must be taken over by adifferent part of the brain.A second possibility is simply that we may acquire languages differently as children than we do asadults.Hirsch thinks that mothers teach a baby to speak by using different methods involving touch,sound and sight.And that is very different from learning a language in a high school or college class.Kim and Hirsch find that children______.A: use the same region in Broca's area to learn their first and second languageB:learn a second language slower than adultsC:are better at acquiring the sound system of a second language than adultsD:use special parts of the brain to program the structures of their first language
