E-book is short for electronic( 電子的) book. It is usually read on personal computers. Some
mobile phones can also be used to read e-books.
Earlier e-books were written for a specific group of readers and were about only a few subjects. With the development of the internet, knowledge and answers to a lot of questions mainly come from e-books. This is why the e-book business is increasing quickly
E-books have many advantages. First, they save time. We don’t need to go to a bookstore to buy books, besides, we can find the topic we want to know about on the Internet, and then we can quickly get many e-books on similar topics. Second, e-books save money. Some e-books cost a little money, and there are millions of e-books on the Internet that we can get for free. Third, more trees are saved because e-books don’t need to be printed(印刷) on paper. Fourth, e-books make reading more convenient. You can carry a whole library of hundreds of books with you in a small computer or any e-book reader (電子閱讀器) without worrying about their weight.
But e-books have certain disadvantages. They need a personal computer or an e-book reader and the information can be lost if its file format (文件格式) is not supported or changed in the reader’s computer.
However, e-books provide us with a new way of reading. That is good.

Who do you admire(崇拜)?Different people may have different ideas.
If you’re a sports fan, perhaps the person you admire most is a great basketball player, and Yao Ming is probably the one in your mind. If you study music or play an instrument, perhaps the person you admire most is gifted musician like Mozart, who began to write beautiful music at a very young age. Or maybe you admire great scientists, for example, Yuan Longping.
We have many reasons to admire famous people and we often give much of our respect to them. However, we shouldn’t neglect those who are common, such as nurses, train drivers, firemen, cleaners and so on. They may be working in a corner of the world without being noticed, but all these people spend their working days serving the public. They show great dedication(奉獻).However, what they do is often unnoticed by us. Have you ever thought of what our life will be like if they stop working?
So next time when you appreciate famous people, don’t forget those who are common around you.

We’ve talked about snails (蝸牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (殼) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (觸角), are very weak. But its sense (感覺) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大頭針). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.

Most children don’t enjoy doing housework. They like playing computer games rather than cleaning the rooms. But in Australia, Jim and Robert’s mother, Mrs Black, has good and proper methods to get their children to do housework.
Here is an example.
“Mum, have you worked out next week’s housework? Let Jim and me choose the cards I can’t wait. It’s fun!”
When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “sweep the floor, clean your bedroom, help mum cook, wash vegetables, make beds, feed the fish, cut the wood, clean the bathroom” and many others, Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the week day task board. Jim likes to clean the bathroom, so he picked up the card “clean the bathroom”. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards
To help the children do housework, their mother thought hard and came up with this idea. Of    course, the parents did the housework on the weekends and left Jim and Robert two days free.

科目：初中英語 來源：不詳 題型：閱讀理解

My class will put on a short play in English at the end of the year. Yesterday our English teacher gave us copies of the play.
“Choose a character in the play whom you’d like to be, ”she told us. “This afternoon learn a few lines of this part for homework. Then tomorrow you can say those lines in front of the class. Ill decide who play each part.”
I wanted to have one of the bigger parts in the play, so I choose the part of the king. He has a lot of lines to say. I learned them by heart.
This morning in our English lesson we had to say our lines. I acted the part of the king. When I said my lines, I put a lot of expression into my acting. I thought I acted really well.
Everyone in the class read a part and then the teacher who would play each part.
Many of the students in my class couldn’t act at all. They couldn’t even read without making lots of mistakes. I was sure that I would get a big part in the play.
However, the teacher gave me the part of a soldier. He has only one line. It is, “Yes, sir!”
I was very disappointed. At the end of the lesson I went up to her and asked her why I had such a small part.
“You put too much expression in your acting,” she said. “Good acting is not big acting. It is acting the audience can believe in.”
I think I know what she means.
小題1: What did the boy want to do in the play?
A．To get a morning eating part
B．To organize the play
C．To get a large acting part.D．To work the lights.
小題2:How did the boy feel when the teacher told the class they would put on a play?
A．Bored. B．Sad. C．Excited. D．Unhappy.
小題3:Why didn’t the teacher give him the part of the kings?
A．He did not act correctly. B．He did not know the lines.
C．He was not handsome. D．He was too short.
小題4: What does the underlined word “expression” in the passage mean?
A．表情B．建議C．模仿D．服飾
