Помогите пожалуйста решить задание по тексту:
XXI century parents
The reason for writing this book was my dissatisfaction with parenting- advice literature. I found it to be riddled with oversimplified messages, and often unrelated to or at odds with current scientific knowledge. My persuasion, therefore, was that parents needed a consistent way of thinking about their role to facilitate children in making effective decisions.
It's little wonder that parents are perplexed about what approach to take to upbringing of their off-springs. Today's world is the one that makes parenting extremely difficult. In many highly developed countries, the majority of mothers of preschool children are in the workforce. Not always this is their choice to start working. Many parents simultaneously complain that they're busier than ever and that due to the growing demands of their jobs, they have little time for their children.
In many countries there exists a phenomenon of "youth alienation" and parents' fear for their own children's futures is quite understandable. But agreement on what parents can and should do to shield children from underachievement and demoralisation eludes those who seek it on the shelves of libraries or bookstores. Parenting advice has always been in a state of continuous motion. While the fundamental goal of parenting - to instil character and moral development - has stood firm among the various passing fashions in child care over the years, the approach to accomplishing this has varied considerably.

Some authors, convinced that parents are in control of what their children become, advise a "get tough" approach. The educational parallel to this "parent-power" example is to train and start education as early as possible, and this has been justified by claims of maximising brain growth or securing high achievement by starting sooner. Other authors, however, attribute many of today's social problems to the excessive pressure put on children by parents. According to these "child-power" proponents, children have their own built-in timetables for maturing and learning. Waiting for cues that children are ready, these experts say, will relieve the stress that fuels youth discontent and rebellion. The reality, however, is that there are no hard-and-fast rules.
Current thinking on child upbringing advice mirrors historical shifts in theories of development and education. The most disturbing trend in the literature has been a move to deny that parents make any notable contribution to their children's development. This public declaration of parental weakness comes at a time when many busy parents retreat from family obligations, and, indeed, it grants them licence to do so.
