The term “Industry 4.0” refers to the fourth industrial revolution. The first industrial revolution was the production of goods with machines like steam engines, which was followed by the second industrial revolution that introduced mass production with the help of electric power, followed by the digital revolution —the use of electronics and IT in production.

Industry 4.0 is a high-tech project, which promotes the computerization of manufacturing (制造业). The basic principle of Industry 4.0 is that by connecting machines, work pieces and systems, we are creating intelligent networks along the entire value chain that can control each other automatically. The goal is the Smart Factory, which adapts well and uses resources efficiently as well as linking customers and business partners with great intelligence. Technological bases are the Internet systems and advanced factories. Experts believe that Industry 4.0 could be a reality in about 10 to 20 years.

So, what effects does this change have on the classic manufacturing? According to an expert, “it is highly likely that the world of production will become more and more networked until everything is connected with everything else.” Networks and processes have so far been limited to one factory. But in the time of Industry 4.0, the boundaries (界限) of individual factories will most likely no longer exist. Instead, they will be lifted in order to inter-connect multiple factories or even geographical regions.

How is an Industry 4.0 factory different from a today’s factory? In current industry environment, providing high-end quality service or product with the least cost is the key to success. Factories are trying to increase their profit as much as possible. In the time of Industry 4.0, various data sources are available to provide worthwhile information about different aspects of the factory. Using data for understanding the current condition and checking faults and failures is a natural thing. The sharing of information around the clock and around the globe will enable these connected systems to manage themselves independently, work more efficiently and identify any errors quickly.

The good news is that Europe is much better prepared for the Industry 4.0 revolution than one might think. Europe will position itself as a pioneer in the fourth revolution. Industry 4.0 is a project in the high-tech strategy of the German government. Meanwhile, in the U.S., some companies are also working hard on it. But the success of industry depends on whether business and politics can work together. It’s not only politics that needs to help open the door for Industry 4.0. Every company is advised to seize the new digital opportunities.

1.What marks the coming of Industry 4.0?

A. Steam engines.　　 B. Mass production.

C. Intelligent networks.　　 D. Use of electronics.

2.Industry 4.0 will probably result in ________ in the world of manufacturing.

A. everything connected with everything else

B. production limited to an individual factory

C. networks and processes no longer existing

D. classic factories stopping their competition

3.What’s the meaning of the underlined part in Para. 4?

A. Sharing information of the world time.

B. Global news broadcast at any time.

C. Spreading news widely on the hour.

D. Instant worldwide information exchange

4.The writer’s attitude toward Industry 4.0 can best be described as ________.

A. negative　　 B. supportive

C. doubtful　　 D. cautious

The Digital Revolution, also known as the Third Industrial Revolution, is the shift from mechanical and analogue electronic technology to digital electronics which began anywhere from the late 1950s to the late 1970s. Central to this revolution is the mass production and widespread use of digital logic circuits, and its derived technologies. These technological innovations have transformed traditional production and business techniques.

1980s

In developed nations, computers achieved ubiquity during the 1980s as they made their way into schools, homes, business, and industry. Automated teller machines, industrial robots, CGI in film and television, electronic music, bulletin board systems, and video games all fueled what became the zeitgeist of the 1980s. Millions of people purchased home computers, making household names of early personal computer manufacturers such as Apple, Commodore, and Tandy. To this day the Commodore 64 is often cited as the best selling computer of all time, having sold 17 million units (by some accounts) between 1982 and 1994.

1990s

The first public digital HDTV broadcast was of the 1990 World Cup that June; it was played in 10 theaters in Spain and Italy. However HDTV did not become a standard until the mid-2000s outside Japan.

The World Wide Web became publicly accessible in 1991, which had been available only to government and universities. In 1993 Marc Andreessen and Eric Bina introduced Mosaic, the first web browser capable of displaying inline images and the basis for later browsers such as Netscape Navigator and Internet Explorer. Stanford Federal Credit Union was the first financial institution to offer online internet banking services to all of its members in October 1994.

2000s

Cell phones became as ubiquitous as computers by the early 2000s, with movie theaters beginning to show ads telling people to silence their phones. They also became much more advanced than phones of the 1990s, most of which only took calls or at most allowed for the playing of simple games.

2010s

By 2012, over 2 billion people used the Internet, twice the number using it in 2007. Cloud computing had entered the mainstream by the early 2010s. By 2015, tablet computers and smart phones were expected to exceed personal computers in Internet usage. By 2016, half of the world's population was connected.

1.According to the passage, which one of the following statements is true?

A. The digital revolution only focuses on the mass production.

B. The World Wide Web became available to government and universities in 1991.

C. Phones of the 1990s merely made calls.

D. The number of people using the Internet in 2007 is approximately 1 billion.

2.What does the underlined word in Paragraph Two refer to?

A. Wide existence. B. Abrupt disappearance.

C. Quick movement. D. Abundant amount.

3.How does the writer develop the whole passage?

A. By presenting times. B. By making comparisons.

C. By listing data. D. By drawing conclusions.

4.What is the best title for this passage?

A. The Traditional Production B. The Digital Revolution

C. The Connected Population D. The World Wide Web

Years ago, I lived in a building in a large city. The next building was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.

After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”

One bright morning I decided to clean my flat, including washing the window on the inside.Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible. Her window was clean!

Then it dawned on me. I had been criticizing her dirty window, but all the time I was watching hers through my own dirty window.That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?

Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world about me more clearly.
