31. 细节理解D。开始的时候作者与Linda总是一起去上钢琴课、看电影、游泳、骑马等，但后来在作者13岁的时候，作者一家搬走了，两人只能通过书信联系。比较四个选项，显然只能选D。
32. 细节理解B。根据文章第2段中的Soon we were busy with children and moving to new homes, and we wrote less often 根据文可知，她们之所以没经常写信，是因为她们要忙于照顾孩子，又要搬新家，也就是说，她们没有时间写信。
33. 细节理解D。根据文章第3段内容可知答案。
34. 推理判断B。真正让作者感到高兴的是当她在电话上听到老朋友Linda的声音的时候。而读到报纸的时候和写信的时候都还只是在猜测，那时还谈不上高兴。
35. 细节理解A。根据文章最后一段中的Minutes later I heard a voice that I knew very much, even after 40 years…可知，答案选A。
