【題目】根據短文內容,回答下列問題。

(2018·山東臨沂)Have you ever counted the number of digits (數(shù)字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. That’s because China has the longest mobile phone numbers in the world. Why is that?

The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider (提供者) you are using For example, 135 is for China Mobile Communications Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you where the number is registered (注冊). And the last four digits are random (隨機的).

The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there were not enough numbers for us to use. So we began to use 11 digits starting from 1999. Eleven digits can be used to make tens of billions of mobile phone numbers. That’s enough for each person to have seven or eight phone numbers to use in China.

And mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven’t contacted (聯(lián)系) for a long time, you may find that its owner has changed.

Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada’s mobile phone numbers are perhaps the shortest in the world: they use seven digits.

【1】Is China the only country that uses 11-digit mobile phone numbers in the world?

________________________________________________________________

【2】What can we know from the fourth to the seventh digits of a mobile phone number in China?

________________________________________________________________

【3】Why does China use 11 digits for mobile phone numbers?

________________________________________________________________

【4】When can a mobile phone number be recycled in China?

________________________________________________________________

【5】Which country perhaps has the shortest mobile phone numbers in the world?

According to the study, teenagers who eat breakfast weigh around 5 pounds less than teenagers who do not.

The breakfast does not even have to be very healthy, as eating anything is better than nothing.

The study also showed that eating breakfast keeps teenagers feeling full for longer, so they will not eat too many snacks later in the day. This is good news as most popular snacks, like sweets and potato chips are usually unhealthy and full of calories.

【題目】（題文）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 hooks, 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 Yao Ming poster on my bedroom wall will ever be replaced by a computer two metres high!

【1】（小題1）What does the writer do before he goes to sleep’?

A. He reads books. B. He reads newspapers

C. He looks through magazines D. He looks at the posters on the wall.

【2】（小題2）When was paper first created?

A. About 2.000 years ago. B. In the 19th century.

C. About 1.000 years ago. D. In the 11th century.

【3】（小題3）Why were books expensive and rare before the invention of printing?

A. People could not read.

B. People could not write words on paper.

C. People could not find silk, cotton or bamboo.

D. People could only produce books one at a time by hand
