根据以下资料，回答5~8题。 Children for whom school has no point Many children do not go

to school either because their parents want them at home as carers for siblings, or simply because their parents cannot be bothered to send them．Thousands more are not registered at any school at all, because of their families' unstable lives. Underlying this dreadful situation there are two central truths．First of all, the problem of children not going to school often has more to do with their parents than with the children themselves．Secondly, once children go to school, we need to make sure that the experience is a positive one so that they want to keep on going. In Britain, the Ministry of Education has introduced a complex package of sticks and carrots to persuade Schools to bring truants' and excluded children back into the classroom．It is paying grants so that a thousand schools can set up special units to help these children．Schools receive the grant if they bring a target number of children back to school; if they do not meet the target, the grant is withdrawn. Parents are the subject of this campaign, too: the Home Office has introduced fines for parents who fail to send their children to school, and has given the police power to pick up truants on the streets. Truant=a child who does not go to school when he or she should. According to the text, there are thousands of children who __. A．run away from school B．live in stable families C．are not registered at any school D．stay at home doing the housework
