听力原文： On Feb 15th, 1989, an instant survey was carried out among 18 overseas postgraduate students. Eleven students were male and seven were female. The purpose of the survey was to discover the views of the students on a number of matters of personal concern. The survey was conducted by means of a questionnaire given to the students to complete. There were five questions. The first question concerned favorite color and the .second favorite number. The next 3 questions were all concerned with aspects of marriage. No. 3 looked at the ideal age to get married, No. 4 examined the qualities looked for in a partner and No. 5 asked about the ideal number of children. The main findings were as follows: Blue was the most popular color. This was followed by Green and Purple. There was no real significance in the choice of lucky numbers. About one third of the students said that they had none. Sixty-one percent of the students selected the age group 26 to 30 years as ideal for marriage, followed by 21 to 25 years. In looking for the most important qualities in an ideal partner, someone hoped the person to be Intelligent, others chose Natural, and still others indicated Attractive and Honest. The ideal number of children was 2, followed by 3. It is not easy to reach any definite conclusions based upon such a small sample of students from such widely different backgrounds. However, it is clear that majority favorite of 26 to 30 is the ideal age to get married with an intelligent partner, thereby producing 2 children.
