Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print
Paper was first created about 2，000 years ago，and has been made from silk，cotton，bamboo, and since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren't many books, few people learned to read.
Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.
Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD ROMs or machines such as MP3 players.
Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day No, I don't think the poster of Yao Ming on my bedroom wall will ever be replaced by a computer two meters high!

A．Because people could not read.
B．Because people could not write words on paper.
C．Because people could not find silk, cotton or bamboo.
D．Because people could only produce books one at a time by hand.
39．What happened after books became cheaper

Can plants talk Modern research has found something amazing: they do communicate with each other.
It has been known for some time that plants use chemicals to communicate with each other. This happens when a plant gets attacked by insects. The plant gives out chemicals from the leaves that are being eaten. This is like a warning, or a call for help: “I’m being attacked!’’ When another plant gets the chemicals, it starts to give out its own, different chemicals. Some of these chemicals drive insects away. Others attract the wasps （黄蜂; 蜜蜂）! The wasps kill the insects that are eating the plants. Scientists hope to learn more about this plant warning system, so that we can use it to grow more crops.
More surprisingly, plants also use sound to communicate. People can't hear these sounds; but plants are making them. Some plants make noises with their and chili plants do this. Some trees make clicking noises when there is not enough water.
Most surprisingly of all, plants have an amazing system of communication that can link nearly every plant in a forest. Scientists call this system the "wood wide web". The wood wide web is linked underground by fungi（霉菌）. It links the roots of different plants to each other. It is in some ways similar to the Internet we use. Using the wood wide web, plants can share information and even food with each other. However, it may lead to bad effects. Plants may use it to steal food from each other, or spread chemicals to attack other plants. Perhaps one day scientists will learn how to create a "firewall" to help prevent these attacks within the wood wide web.
Scientists are learning more every day about the secret ways in which plants talk to each other. Maybe one day we will know enough about plant communication to be able to "talk" with them ourselves.
66. What will plants do when they are attacked by insects
A. They will kill the insects by themselves.
B. They will control the wasps to kill the insects.
C. They will send out signals to ask for help.
D. They will produce chemicals as a warning or a call for help.
67. How are the wood wide web linked by fungi
A. By making noises with their roots.
B. By connecting the roots of different plants to each other.
C. By sharing food and information with each other.
D. By spreading chemicals to each other.
68. What is the writer's intention of the last paragraph
A. To give people hope for further studies. B. To praise scientists for their great achievements.
C. To call on people to protect the plants on Earth. D. To inspire people to communicate with plants
The passage is most probably from _______.
a science book B. a travel guide C. a story book D. a health magazine
