The inventor was Lu Ban. He was born in the state of Lu in ancient China more than 2,500 years ago. That is where Qufu lies in the east of Jining. Lu Ban was the greatest carpenter(木匠) in his time. Once the king ordered him and his team to build a palace in a very short time. They would be punished if they missed the deadline(最后期限). They had only axes, or fuzi in Chinese, to cut the trees and prepare the wood for the palace, so the work went very slowly. One day Lu Ban rushed up the hill to see how things were going. Suddenly the sharp teeth of a leaf cut his hand. Then a bright idea came into his head. Soon he made a tool with teeth along the side of a long iron bar(条状物). With this tool, work became much faster, and they completed the work before the deadline. That is how the saw was invented. Lu Ban invented many other useful tools for carpenters and interesting toys for children. The Wooden Bird, for example, could stay in the air for three days! 1. In which picture can you see a saw? 2. What did the king order Lu Ban and his team to do? A. Use only axes. B. Build a palace quickly.  C. Cut the trees. D. Prepare the wood. 3. What does Paragraph 4 mainly tell us? A.

A ship. D. A car. 5. Which is the right order of the events according to this passage? a. Lu Ban invented the saw. b. Lu Ban had a bright idea. c. Lu Ban was ordered to build a palace. d. Lu Ban’s team finished the work. e. Lu Ban’s hand was cut. A. a‑e‑b‑c‑d B. e‑b‑a‑c‑d  C. c‑b‑a‑d‑e D. c‑e‑b‑a‑d 参考答案： 1. B 表示“一副眼镜”要用 a pair of glasses。故选B。 2.
