根据短文内容,回答下列问题。
(2018·山东临沂)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. 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 (注册). 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 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 (联系) 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.

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. 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 pare has a different meaning. The first three numbers tell you which mobile phone service provider you are using. For example,135 is for the China Mobile Communications Corporation ( 中 国 移 动 ) and 188 is for China Unicom ( 中 国 联 通 ). The fourth to the seventh digits tell you which region the number is registered (注册) in. 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 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.
Plus, 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 for a long time, you may find that its owner has changed.

Creator of e-mail makes use of ‘@’ sign
Does your class use e-mail? Have you ever tried to write a story for our newspaper and send it in by e-mail? E-mail is used for everything, and it makes life easier. But do you know where e-mail came from?
The man who invented it was Ray Tomlinson, a US engineer. He died early last month at the age of 74.
Back in 1971, Tomlinson was working on something that could send messages from one computer to another. Tomlinson tried to find a way to separate users’ name from the names of their computers. He needed some kind of symbol (符号). However, it couldn’t be a popular one, and it couldn’t be one that computers might know in a different context (语境). It also needed to be on keyboard at the same time. The “@” sign was there, and pretty much no one used it. It was perfect.
“The ‘@’ sign made the most sense,” he told Wired in 2012. “It said where the user was…at.” For example, by writing “Alex at 21st Century Teens” you can send a message to somebody named Alex who works at 21st Century Teens. This was the early form of email.
The interesting thing is that Tomlinson didn’t remember what the very first test message he sent was. “Probably the first message was QWERTYUIOP or something like that,” Yahoo reported, guessing the first row of letters on the keyboard.
Tomlinson, the father of e-mail, changed the way the world communicates and more importantly saved the symbol “@”.
Today, the “@” symbol is finding new life outside of our inboxes (收件箱). Most famously, social media like Weibo and Wechat use it at the beginning of user names. So even if we don’t use e-mail some day, Tomlinson’s contribution (贡献) will certainly live on.
1.Who invented the e-mail?
_____________________________________________________________________
2.When did he invent the e-mail?
_____________________________________________________________________
3.Why did he choose the symbol “@”?
_____________________________________________________________________
4.What does “@” sign tell us?
_____________________________________________________________________
5.What’s the passage mainly about?

Have you ever heard of e-books? E-books are electronic books. They are no larger than an ordinary(普通的)book, with a screen on which you can read.
How does the e-book work?
First, you call up websites on your computer and choose books that you want. There are thousands of books provided by different websites on the Internet. Then download the books you like on to your e-book. You can download about 10 books at a time. Now you can just sit back and enjoy yourself reading.
Compared with ordinary books, e-books have many advantages. First of all, e-books save space. You can put as many as 10 books into a thing no bigger than a pocket radio and then carry it everywhere. You can renew(更新) reading materials in your e-book as many times as you like. With the development of e-book technology, probably an e-library will appear. Then you just take your e-books there and download what you want to read. You no longer need to worry about whether your books are over-due( 逾期 )or not.

Rooftop Gardens
Have you ever seen a rooftop garden—
a garden on the top of a roof? Many people are
finding it good for the environment and good for
themselves.
Cities can be as much as 4—10 degrees
warmer than the countryside. Green rooftops
can actually help cool the air in cities. A single green roof will not do much to change the temperature of a city. However, when more buildings begin to change their rooftops into green spaces, it makes a real difference. Buildings that are cooler also use air conditioning less often. This reduces the amount of energy a building uses, which is good for the environment. Cities are usually more polluted than other areas. Plants on rooftops can even help clean the air. Gardens in the city can also provide a place for birds and bugs to live in.
One unusual rooftop garden is located above Children’s Hospital in St. Louis, Missouri. The garden covers an area of 7, 500 square feet. The garden has flowers, fountains (喷泉),even a goldfish pond, and also paths that children can walk on in slippers or with bare feet. It is used as a place for the children and their parents to relax and be close to nature without leaving the hospital. Another interesting garden is on the rooftop of the Royal York Hotel in Toronto, Canada. A large vegetable garden has been planted on the roof. The hotel’s chefs (厨师)can pick fresh vegetables from the roof.
Now not all buildings have rooftop gardens. One reason is that rooftop gardens can be more expensive than traditional rooftops. However, they may save on heating and cooling bills in the future. Also, a roof needs to be flat and strong enough to support the weight of the garden.
Some people may not know about rooftop gardens and how good they can be for the environment. But word is starting to get out. You may want to keep your eyes on the skies when you walk in your town or city. You never know when you might find a secret garden many feet above the ground.
1.What is a rooftop garden?
2.What is the second paragraph mainly about?
3.What is the rooftop garden in Children’s Hospital in St. Louis used as?
4.Why is the rooftop garden of the Royal York Hotel interesting?
5.Why don’t all buildings have rooftop gardens?

Have you ever wondered what an American high school is really like? This article will describe a typical (典型的) high school and its students.
A typical American high school has several large buildings and enough space for about 1,500 students. Every student is given a locker. When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather borrow than buy them. Students must pay back if they lose any of them.
American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. Sometimes their parents drive them to school. When they turn 16 years of age, most take a free driving class at school for one term. If students get passing grades in the class and also pass their state driver’s exam, they can begin driving themselves to school.
Each day, students take six or seven classes. They must take science, maths, English and social studies. They can choose art, homemaking, clothes making and other classes. In some schools students are asked to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.
The school day usually ends early in the afternoon. After school more than half of the students take part in after-school activities. These activities include sports --- especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, and photography and student government.
1.How many students are there in the typical American school?
2.What do they do first when they arrive at school?
3.What subjects must they study?
4.What do they do after school?
5.What can you learn about the American school life from the passage?
