Question 25 is based on the passage you have just heard.

    (22) When children start school for the very first time, parents often feel a sense of excitement coupled with a touch of sadness at the end of an era. This is the start of a new adventure for children, playing and interacting with new friends, sharing, taking turns and settling into a new routine.

    (23) But of course, this is not the start of your child’s education which in fact began at birth. Back then, you would have been your child’s most influential teachers. During this time at home, your child would have learnt more than at any other period in their life. During your child’s first year in school, much time will be spent in learning to read and they need to know that this is fun and worthwhile. (24) Your child will naturally copy you so it is important that you are seen reading and enjoying books, newspapers and magazines rather than just absorbed in screens. Ultimately an excellent education should be a close partnership between parents and teachers. A child’s year splits fairly neatly into thirds: a third at school, a third asleep and a third awake at home or on holiday.

    (25) Irrespective of the quality of a school, a child’s home life is of key importance. It is the determining factor of their academic success. Your child may have started on a new journey but your work is far from finished.

25. What does the passage say is the key factor of children’s academic success?

解析：B。根据录音可知，不管学校的教学质量如何，孩子的家庭生活是至关重要的。这是他们取得学术成就的决定性因素。故正确答案为B。
