I was searching for just the right word to describe this book; a word that describes something that is perhaps somewhat sad， but in a good way. I couldn't find quite the right word， but I do know the feeling.
This book does make me feel a bit sad. Sad for the way that childhood passes so quickly， sad for days that go by， faster than we‘d like them to. But it also makes me feel the sweetness of these things and helps me remember that childhood imagination， freedom and joy are things that we can carry with us still， long after our days as children have passed.
Which of the following is true about the author‘s feeling of the book?
makes him feel sad for his childhood is sad.
makes him feel sad because he didn‘t remember his happy childhood.
couldn‘t describe the book， for he doesn’t know the feeling.
realizes that childhood imagination， freedom and joy are things that he can carry even when he is an adult.
正確答案：D
答案解析：答案選D。細節理解題。 通過本段第二句I couldn't find quite the right word, but I do know the feeling...可排除C。通過第四句Sad for the way that childhood passes so quickly可以知道他感覺悲傷是因爲童年時光匆匆而過，而不是因爲他的童年是悲傷的，文中並未提及。所以A不對。同理文中也並未提及他感到悲傷是以爲他沒有了童年的回憶，故B也不對。而可以通過最後一句話得出D是對的。
