四川省眉山市仁寿县华兴联谊学校2019年九年级英语“二诊考试”试卷(含听力音频)

根据短文内容,从下面方框中选择适当的选项补全短文。

A. Each part has a different meaning.

B. So they cannot create as many numbers as we can.

C. That's because China has the longest mobile phone numbers in the world.

D. Also, mobile phone numbers can be recycled.

E. The main reason for using 11 digits is that we have the largest population in the world.

    Have you ever counted the number of digits (数字) in your mobile phone number? Your number has 11 digits. You may sometimes find it hard to remember your number. Why is that?

    The 11 digits can be divided into three parts. The first three numbers tell you which mobile phone service provider you are using. For example, 135 is for the China Mobile Communication Corporation and 188 is for China Unicom. The fourth to the seventh digits tell you which area the number is recorded in. And the last four digits are random (随机的).

    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, according to the Xinhua News Agency. That's enough for each person to have seven or eight phone numbers to use in China. Usually, the service provider will reuse a canceled number after three to six months. If you call a number that you haven't contacted (联络) 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. 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.

举一反三
Answer the questions.

    Car Free Day encourages drivers to give up their cars for a day to protect the environment. People from around the world get together in the streets to remind the world that we don't have to; accept the society full of cars. It started from France in 1998. Because of the air and noise pollution, some French young people wanted a day without cars. On September 22nd, people in 35 cities in France didn't use their cars. They went to work or school by bike, bus or on foot. After that, September 22nd became Car Free Day. The first Car Free Day in China was in Chengdu in 2001. The slogan(口号) for the day is "If we, drive for one less day, we can have one more nice day."

    Organized activities are held in many cities on Car Free Day. In Brussels, Car Free Day shall be valid(有效的) for everybody except persons with a special permit(许可证),but they have to slow down to the speed of 30 kilometres per hour. The public transportations are encouraged. The streets are open only to walkers, bicycles and buses from 7:00 a.m. to 7:00 p.m. In Beijing, it asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. More and more people are taking part in the activity. In the first quarter of this year, Beijing only had 52 blue sky days, and you may see haze almost every day! We must do more for Car Free Day as a Beijing driver said, "We may not change the weather, but we can choose not to drive."

    But we do not want just one day and then a return to "normal" life. We should go on with Car Free Day.
