Questions 36—40 are based on the following passage:

Passage 4

   However important we may regard school life to be, there is no gainsaying(否认)the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong helpers of the school personnel or they can consciously or unconsciously hinder and oppose curricular objectives.

   Administrators have been aware of the need to keep parents informed of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics.

   Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’ progress, can significantly aid in achieving a harmonious interplay between school and home.

   To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent convert his natural paternal (父亲的)interest into productive channels. He might be persuaded to let Junior participate in discussion the family budget, buying the food, using a yardstick or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.

   If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.

   Too often, however, teachers’ conferences with parents are devoted to petty accounts of children’s unlawful acts, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home.

   What is needed is a more creative approach in which the teacher, as a professional advised, plants ideas in parents’ minds for the best utilization of the many hours that the child spends out of the classroom.

   In this way, the school and the home join forces in fostering the fullest development of youngsters’ capacities.

36. The author directly discusses the fact that         .

  A. parents drill their children too much in arithmetic

  B. a parent’s misguided efforts can be properly directed

  C. a father can have his son help him construct articles at home
