One day,while walking in the street,Bi Sheng noticed two children were making little toys like people and pigs out of the mud and putting them in different orders.This gave Bi Sheng a great idea.He thought that he could make the characters first and then put them in orders like the mud toys. After much thought and experiments,Bi Sheng decided to use clay.He pressed the clay into small pieces and cut one character on each piece.Then,he put these clay pieces into a fire to make them hard.Then he put the clay characters in an iron frame to form a page.After that,ink was put on the clay characters.A piece of paper was placed on the top and the inked characters appeared on it with a gentle press.After printing,the clay characters can be kept and reused. This movable type printing(活字印刷术)made making books much quicker and easier.However,some people didn't believe in this new invention.But Bi Sheng didn't give up and worked hard to make it better.Today,his invention still has a big influence in China.It shows us that with creativity and hard work,we can also do great things and make the world a better place.

You can have wild and crazy thoughts.Remem- ber that no idea is too silly().Many people laughed at the Wright brothers and said they would never fly.But they weren't discouraged by what people said.That's why now we have planes. Careful planning is important in the invention process.This is the time to brainstorm for ideas and to evalu- ate(评估)them. Make a detailed(详细的)drawing of your in- vention so others will understand how your invention works. Make a model of your invention. See if your invention works as it is planned.If not,do more research,redesign it and test it again. Every invention needs a name.

D The Chinese abacus (is known as suanpan.This ancient calculating device,with its origins dating back thou- sands of years,is a cultural artifact(文化产物).It is usually 15 cm wide and comes in different lengths.It usually has more than seven rods(杆子).There are two beads(算珠)on each rod in the upper deck and five beads each in the bottom deck. The beads are usually round and made of wood.The beads are counted by moving them up or down towards the beam 梁).①If you move them toward the beam,you count their value.If you move away,you don't count their value. Skilled operators can quickly perform addition,subtraction, multiplication,and even division.Suanpan can be reset to the starting position quickly,so you can start to count again easily with it.② In conclusion,the abacus has played a significant role in the development of human civilization.In Japan,the abacus is called soroban.3 It was brought from China to Japan in the 14th century.The use of soroban is still taught in Japanese primary schools as part of maths. Today,many children in China also learn to use suanpan in after-school classes.Although we now have calculators and computers,suanpan is still a fun and useful tool for learning maths.It shows the wisdom(智，慧)of ancient people and re- minds us that learning can be hands-on and interesting.4 ()66.What is the writer's main purpose in writing this pas- sage? A.To explain how the suanpan works and show its educational value. B.To prove that suanpan is faster than any modern computer. C.To ask schools to stop teaching students calcula- tors. D.To describe the differences between wood and plastic beads. ()67.What can we learn about the size of a common su- anpan? A.It is always 15cm long. B.It becomes shorter when more rods are added. C.Both length and width are exactly 15cm. D.Its width is the same,but its length is different. )68.If a suanpan has 9 rods,how many beads are there in the upper deck altogether? A.9. B.18. C.27. D.45. )69.Where should the sentence "This quick reset'func- tion makes the suanpan better than doing sums( 计)on paper.”best be placed? A.(D B.② C.③ D.④ )70.Why is suanpan still used today? A.Because it is faster than computers. B.Because it is required in all schools. C.Because it is fun and helps children learn maths. D.Because it is cheaper than calculators. 第二节阅读表达（共5小题；每小题2分，满分10分） 阅读下面短文，简略回答问题。 Men always wanted to fly in the sky.They watched birds flying and wished they could fly too.Men made wings and tied (them on their bodies to help them fly.But they failed again and again.Men knew how to make kites.They made dif- ferent kinds of kites and tried to fly with the help of them.But unluckily,many of them were badly hurt.So they had to stop trying to fly with wings.
