三、阅读理解
（A）
Do you know your mobile phone number well? Your number has 11 digits（数字）. 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 include three parts. Each part has a different meaning. The first three numbers tell you the mobile phone service provider you are using. For example, 135 is for the China Mobile Communication Corporation（中国移动）and 188 is for China Unicom（中国联通）. The fourth to the seventh digits tell you where the number is from. And the last four digits are random (随机的）.
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 from 1999.
Eleven digits can 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. Also, we can use the mobile phone numbers again. Usually, the service provider will use a cancelednumber again after three to six months. If you call a number that you haven’t called for a long time, you may find 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 make 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 world’s shortest: they use seven digits.
26．What can we learn from the mobile phone number 188-4792-83437?
A．The service provider is the China Mobile Communication Corporation.
B．The digits 4792 tell you the area the mobile phone number is from.
C．There are ten digits in the mobile phone number.
D．The digits 8343 tell you the number of service providers in China.
27．Why do we use 11-digit mobile phone numbers in China?
A．There are many people in China.
B．People in China can remember numbers well.
C．11 is a lucky number for Chinese people.
D．It helps people to remember more phone numbers.
28．What does the underlined word “canceled” mean in Chinese?
A．新型的B．已撤销的C．有用的D．特殊的
29．________ can make the most mobile phone numbers.
A．10 digits starting with 1B．11 digits starting with 0
C．11 digits starting with 1D．10 digits starting with 0
30．Which countries use phone numbers with 10 digits?
A．Britain and Japan.B．Britain and China.
C．Canada and Australia.D．India and Australia.
【答案】26．B27．A28．B29．C30．D
【文章大意】本文主要介绍了中国手机号码为什么是11位，并介绍了其他国家手机号码数字。
【解析】
26．细节理解题。根据“ The fourth to the seventh digits tell you where the number is from.”可知第四到第七位数告诉你这个号码是来自哪里。故选B。
27．细节理解题。根据“The main reason for using 11 digits is that we have the largest population in the world.”可知使用 11 位数字的主要原因是我们拥有世界上最多的人口，故选A。
28．词句猜测题。根据“ Also, we can use the mobile phone numbers again. Usually, the service provider will use a canceled number again after three to six months. If you call a number that you haven’t called for a long time, you may find its owner has changed.”可知如果你拨打一个你很长时间没有拨打的号码，你可能会发现它的主人已经变了。由此推测此处是表示服务提供商会在三到六个月后重新使用被取消的号码，划线单词表示“已撤销的”。故选B。
29．推理判断题。根据“Eleven digits can make tens of billions of mobile phone numbers..”以及“Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot make as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. ”可知除了中国，英国和日本也使用11位的手机号码。但它们的数字总是以0开头。所以他们的号码不如我们的多。因此根据文中并结合常识可知以1开头的11位数字可以构成最多的电话号码，故选C。
30．细节理解题。根据“ Countries like the United States, Australia and India use phone numbers with 10 digits. ”可知美国、澳大利亚和印度的电话号码是10个数字。故选D。
