Many schoolteachers say that as difficult as their students can be to deal with, parents c

an be even worse. Some parents are quick to【C1】______and protest when their son or daughter gets in trouble or performs poorly on a test.

And she has had parents say they are paying a lot of money for their child s education and【C4】______that anything but an A is an unacceptable【C5】______on their investment." Such parents are doing their children no favors. In fact,【C6】______" rescuing" their children, they are preventing them from " having real experiences of decision making, failing, and【C7】______their own messes," writes the report. The author adds: " If parents run too much interference【C8】______problem solving for their children while the children sit back and do【C9】______the parents will get stronger,【C10】______the children get weaker and fall over when they try to run on their own."
