听力材料
After printing was invented, knowledge was spread around the world by books. For many years, books were very expensive. Each one was written by hand, so very few books were produced. Today, books are produced quickly. They’re light, cheap and easy to get hold of.
But the early books are now too valuable to be picked up and held in the hand, so here in the British Library, they were copied onto a computer a few years ago. Have a look at the screen here. You can turn the pages on the screen, without touching the real books.

√
课文呈现
The Internet was invented by the US government in the 1960s, for the army to use. In the 1970s, scientists and businesspeople also wanted to use the Internet to send and receive messages. For some years, people could only send very simple texts. They could not send photos or documents by the Internet.
That changed in 1991, when a British scientist named Tim Berners-Lee invented the World Wide Web.
课文呈现
The World Wide Web allows people to send various types of files, such as texts, photos and videos by the Internet, so more and more people started to use it in the 1990s. ①
Today, the Web has hundreds of millions of users. It has changed the way people live, work and play. Through the Internet, email allows us to communicate nearly instantly with people thousands of miles away. People and businesses use e commerce and online shopping to buy and sell things across the world.

课文呈现
The Web also makes people's lives easier because now many things can be done from home, twenty- four hours a day. The Web can help you do research for your homework, so that you do not need to go to the library. You can use Internet banking, instead of going to the bank. And, of course, people just“ surf the Web” when they want to relax.
Technology changes quickly, and it is hard to imagine what the future of the Internet and the Web will be. But it seems impossible to imagine life without them.

E-books
Just as email has changed the way we write to each other, e books are changing the way we read. We can easily download new e- books from the Internet. It is much easier and quicker to search for passages now, and we can also write notes in an e- book. ② What is more, they save a lot of paper. But e book readers are still more expensive than paper books, so not all people can afford them. ③
课文呈现
However, with the rapid development of electronic technology, reading e-books will become cheaper and cheaper. A lot of people think there will be more e-books than paper books in the near future.

考点1
一般将来时的被动语态
一般将来时的被动语态结构形式如下:
(1) 表示肯定: 主语+will+be+ 动词的过去分词
e.g. A new stadium will be put up here.
一个新的体育场将在这里被建造。
考向
(2) 表示否定: 主语+ will + not + be + 动词的过去分词
e.g. A new stadium will not(won’t) be put up here.
一个新的体育场将不会在这里被建造。
(3) 表示疑问:
① Will+ 主语+be+ 动词的过去分词
简略回答: Yes, 主语+ will./No, 主语+ won’t.
e.g. —Will a new stadium be put up here
一个新的体育场会被建造在这里吗？
—Yes, it will./No, it won’t. 是的, 会。/ 不, 不会。
② 特殊疑问词+will+ 主语+be+ 动词的过去分词
e.g. —Where will a new stadium be put up

考题在线1: —Would you like to go shopping with me after lunch
—I’d love to, but I ______ to go out this afternoon. [菏泽]
A . don’t allow B. will allow
C . won’t be allowed
C
【点拨】考查动词语态。分析本空所在句子结构可知, 本句的主语I 是动作allow 的承受者, 应用被动语态。
使用一般将来时的被动语态时, 应注意以下两点:
(1) 在时间、条件状语从句中, 应使用现在时表示将来。同样, 应使用现在时的被动语态表示将来时的被动语态。例如: He says he will leave the company if he is punished for this. 他说如果他因此而受惩罚, 他将离开公司。
(2) 使用一般将来时的被动语态时, 学生易遗漏被动式中的be。
e.g. When will these books published (×)
When will these books be published (√)
将在什么时候出版这些书？
其他结构
考点2
表示将来意义的被动结构还有:
(1) be going to be done
e.g. Some old buildings are going to be pulled down.
一些老建筑将被拆除。
考向
(2) be to be done
e.g. A big water park is to be built here next year.
一个大型水上公园明年将被建造在这儿。
(3) will(shall) + get + done 等
e.g. The workers will get paid before the end of December.
工人们将在12 月底前被支付工资。
同学们也要注意这些结构的否定形式、疑问形式等。
e.g. These trees are not going to be cut down.
这些树将不被砍伐。
—Are these trees going to be cut down
这些树将被砍伐吗？
—Yes, they are. 是的, 它们将被砍伐。
考题在线2: The students _______ on everything they have learnt this year.
A. is going to be examining
B. are going to examine
C. is going to be examined
D. are going to be examined
【点拨】用语法判定法解题。“The students”为主语, 谓语动词应用复数形式, 并且主语和谓语动词之间是被动关系。

范文赏析
Mobile Payment Changes Our Life
More recently, mobile payment is liked by many people. It is becoming more and more popular in China. It has made people's daily life very convenient. Most of us are used to paying by scanning QR codes. By mobile payment, we can pay easily and quickly wherever we go. We can have dinner in a restaurant and pay by scanning QR codes with our smart phones.
In a cinema, we can buy our tickets in the same way. Mobile payment is changing our life.
However, we should spend money wisely. First of all, think twice about what we want to buy. Next, learn to save, buy what we can afford. Last but not least, spend money on what we really need, and don’t buy everything we want.

添彩点: 短语运用恰到好处: more and more, be used to, by..., first of all, spend... on 等; 多种句式的巧妙使用: It has made sth.+adj. ...; We can...; We should... 等。
