Read the passage and match the main ideas with the paragraphs. a) The world before printed books b) The world after the invention of printing c) Life with paper and printing d) Technology and books e) The future of books1234Will books be replaced by the Internet? Every morning, my father buys a newspaper on his way to work. Every day, I open my books in class and start my lessons. Every evening, my mother looks through magazines athome. And very night, I look at the photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or printing? Paper was first created about 2,000 years ago in China. After its invention, people started to write on paper to make a book. In those days, books were only produced one at a time by hand. As a result, there were not many books, and they were expensive. So, few people had the chance to learn to read. Printing was invented in China during the Sui and Tang Dynasties. Later, developments in printing made it possible to produce books more quickly and cheaply. A trade in books resulted, and more peoplelearnt to read. Knowledge and ideas spread faster than ever before. In a way, we can compare the invention of paper and printing to the introduction of the Internet in the twentieth century. Although the Internet is still young, it is growing very fast, and may become more powerful than printing. A much larger amount of information can be stored on the Internet than in books. Someone with an Internet connection can find information much more easily than they can find in printed forms. And the machines we use to read it are now small and light, often smaller and lighter than a single book. Computers and the Internet are used in classrooms now, and newspapers and magazines are already read online. So what direction will traditional printing take in the future? Will books be replaced by the Internet? Lets wait and see.To find information in a passage quickly, you can read the heading and the first sentence in each paragraph.

A much larger amount of information can be stored in more varied forms on the Internet than in books. As a result, in the future, the Internet will probably be more important than printing.語法聚焦語法聚焦(參照(參照巴蜀英才巴蜀英才p76內(nèi)容。)內(nèi)容。) 一般將來時(shí)的被動(dòng)語態(tài)一般將來時(shí)的被動(dòng)語態(tài)(1)基本結(jié)構(gòu):基本結(jié)構(gòu):will be+及物動(dòng)詞的及物動(dòng)詞的過去分詞;過去分詞;be going to be+及物動(dòng)及物動(dòng)詞的過去分詞。詞的過去分詞。The painting exhibition will be held on Monday.這個(gè)油畫展將在周一舉辦。這個(gè)油畫展將在周一舉辦。The book review is going to be written by Li Lei.這個(gè)書評將由李磊來寫。這個(gè)書評將由李磊來寫。(2)否定句及一般疑問句結(jié)構(gòu):上述否定句及一般疑問句結(jié)構(gòu):上述兩個(gè)結(jié)構(gòu)變否定句分別是在兩個(gè)結(jié)構(gòu)變否定句分別是在will后后加加not或者在第一個(gè)或者在第一個(gè)be后加后加not;一般疑問句則分別是把一般疑問句則分別是把will或或be動(dòng)動(dòng)詞提到句首。詞提到句首。The painting exhibition wont be held on Monday.這個(gè)油畫展不在周一舉辦。這個(gè)油畫展不在周一舉辦。Will the painting exhibition be held on Monday?這個(gè)油畫展將在周一舉辦嗎這個(gè)油畫展將在周一舉辦嗎?語法聚焦語法聚焦(參照(參照巴蜀英才巴蜀英才p76內(nèi)容。)內(nèi)容。)Is the 2016 Olympic Games going to be held in Russia? 2016年奧運(yùn)會(huì)是將在俄羅斯舉辦嗎?年奧運(yùn)會(huì)是將在俄羅斯舉辦嗎?(3)特殊疑問句結(jié)構(gòu):)特殊疑問句結(jié)構(gòu):特殊疑問特殊疑問詞詞+will +主語主語+be+動(dòng)詞的過去分詞?動(dòng)詞的過去分詞? 特殊疑問詞特殊疑問詞+be +主語主語+going to be+動(dòng)詞的過去分詞?動(dòng)詞的過去分詞?Where are the trees going to be planted, on the hill or in the park? 這些樹要種在哪里,山上還是公這些樹要種在哪里,山上還是公園里?園里?請同學(xué)們完成請同學(xué)們完成巴蜀英才巴蜀英才英語英語九年級上,九年級上,P73-P76 Unit 2 的相應(yīng)練習(xí)。的相應(yīng)練習(xí)。請同學(xué)們在課后參照巴蜀英才英語P75/76的內(nèi)容進(jìn)行復(fù)習(xí)。Later, developments in printing made it possible to produce books more quickly and cheaply.后來,印刷術(shù)的發(fā)展使更快更后來,印刷術(shù)的發(fā)展使更快更便宜地制作書籍成為了可能。便宜地制作書籍成為了可能。make it possible to do sth.意意為為“使某事成為可能使某事成為可能”。其。其中中it是形式賓語,真正的賓是形式賓語,真正的賓語是后面的動(dòng)詞不定式語是后面的動(dòng)詞不定式to do sth.,形容詞,形容詞possible作賓語作賓語補(bǔ)足語。補(bǔ)足語。Spaceships make it possible to travel to the moon.宇宙飛船使去月球旅行成為宇宙飛船使去月球旅行成為可能??赡??!就卣埂俊就卣埂縨ake it+形容詞形容詞+不不定式或從句,意為定式或從句,意為“使得做使得做某事變得某事變得”,其中的形容,其中的形容詞通常是表示事物性質(zhì)的詞通常是表示事物性質(zhì)的easy,difficult,interesting等。等。His lessons make it easy to learn English. 他的課使得學(xué)英語很容易。他的課使得學(xué)英語很容易。back
