　　(3) Children who spend large amounts of time with their fathers have higher IQs, according to a new study. Strong fatherly involvement in their early life can also improve a child’s future career prospects, the research shows. The researchers warned that it was not enough for parents to live together, (3) but that a father should be actively involved in a child’s life to benefit their development. Those children whose fathers spent more time with them had a higher IQ and were more socially mobile than those who had received little attention.
　　Jon Davies, chief executive for Families Need Fathers, said, (4) "We hope that research like this will lead the government to reconsider how poorly served separated families often are and how a child needs a father as well as a mother. "
