Panpan’s Summer Vacation--DAY 6 It rained heavily that day. Panpan had to stay at home. He finished his homework and selected a book from the shelf. Panpan took the book on the desk and began to read. That book was called the Children’s Encyclopedia (insects volume). “It’s amzing that the spider is not an insect!” Panpan said when he read the chapter of the spiders, “I will ask Lanlan to see whether she knew.” Then Panpan called Lanlan and asked her a question. “Lanlan, I found out a question when I read the book, can you help me?” “Of course, Panpan. What’s the question?” “The question is whether the spider is an insect.” “An important feature of the insects is that they all have six legs. Panpan, can you tell me how many legs a spider has?” “Eight legs.” “So, it’s obvious that the spider is not an insect.” “If the spider is not an insect, what animal does it belong to?” “The spider is an arachnid.” “Wow, you are so knowledgeable that no question can beat you.” “Thank you! If you read many books and think more, you will be knowledgeable too.”
