The Home-schooling

Sometimes,the line between private and public education can become very vague.Educators in the United States are wondering whether children who are taught at home should get some public services or how this growing practice(about 3 percent of American students are not fully registered in schools but receive education at home)should be regulated.
In many western countries,many private schools are founded by religious bodies. Approximately haff the parents who decide to teach their kids at home are motivated religiously and use lessons by Internet or mail from church schools.Probably an additional fourth have some doubts about public education.They believe that regular schools don't meet the special needs of their children.It also happens that home-school is adopted by parents to escape compulsory education,for example,some selfish parents have older children take care of his or her younger siblings（兄弟姐妹）or work in home businesses while only teaching them for a very short time.Weakness in regulations in most states of the US means that officials seldom monitor or challenge parents who say they are teaching their children at home,although children often learn well in home-schooling. With growing frequency,however,public schools offer services to the home-schooled.Local government may allow children who receive education at home to enroll local school part time.However,educators have concerns that these kids could later return full time,but their serious academic weaknesses may lead them to falling behind in their studies,and some districts wanting to qualify for state aid can benefit from kids who used to study part time to fill empty seats.
In Kent,Ohio,Mrs. Ringer taught her three children at home in the past years while operating her bakery business there in the non-teaching hours.Mrs. Ringer said to our reporter that her motive was to give her children more training in basic curriculum,such as phonics（读音法）.Her curriculum is from a church school,and relevant tests are handed in and returned via e-mail.
Three years ago her second child,Mark,wanted to join school programs regularly,and he enrolled at the local high school.Unable to keep pace with his classmates,Mark soon changed his mind and decided to continue studying at home.But he enjoyed the athletic program and chorus at school,
so he was allowed by Mr. Ringer to continue in them while taking other courses at home. What is the major concern of educators for the home-schooled kids who returned to school later?
A.They can only enroll part time.
B.They are not qualified to get the state aid.
C.They may occupy the empty seats of classrooms.
D.They may not be able to catch up with their classmates.
