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 com
pany 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.

In Japan, Christmas just isn’t Christmas without butter. That’s because the Japanese love to celebrate Christmas Eve with "Christmas cakes," which are filled with whipped cream (生奶油) and topped with strawberries. Making this tasty treat requires some serious amounts of butter. But this year, the creamy golden spread is in short supply on the island nation.
In fact, many Japanese supermarkets are fresh out of dairy (milk) products entirely. Those that do still have butter often limit shoppers to one box apiece, and the price for that box is much higher than normal.
Northern Japan has been suffering unusually old winters in recent years, and all of Japan has had to endure (忍受) hotter summers. This extreme weather has stressed out the nation’s dairy cows. They have not been able to produce their expected amount of milk.
However, even before the bad weather, Japan’s butter supply was in trouble. The number of dairy farms in the country has been steadily shrinking. Not many young people in Japan want to become dairy farmers anymore.
The demand for dairy products in Japan has also been falling. The Japanese diet consists mainly of rice and seafood, and it often doesn’t require many milk products. So the government decided to cut back the number of the country’s dairy cows in 2007. This led to a butter shortage in 2008 as well as the current shortage.
The Japanese government has tried to increase the stock of butter by importing (进口) about 10,000 tons from overseas. But even this emergency supply has done little to end the shortage this Christmas season.
Blogger Audrey Akcasu says Japanese people are using substitutes in their cooking or paying more money for real butter.
"Some bakeries are choosing to replace butter with margarine (人造黄油) this year, claiming the slight change in taste will be less noticeable than the potential higher price we would see if they used imported butter," she writes in Nikkan Gendai, a Japanese newspaper. "But for many shoppers, it’11 have to be margarine or nothing this Christmas."
1.What does the underlined part in Paragraph 1 refer to?
A. The milk. B. The butter.
C. The strawberry. D. The Christmas cake.
2.Which of the following is probably very popular in Japan?
A. Being dairy farmers.
B. Enjoying various dairy products.
C. Eating cakes at Christmas.
D. Tasting margarine rather than real butter.
3.Which of the following is Japan actually facing now?
A. A cow crisis. B. Much milder winter.
C. A shrinking population. D. Continually falling food prices.
4.What does Audrey Akcasu think of the government’ s importing butter from overseas?
A. It’ s wise. B. It’ s unnecessary.
C. It’ s ineffective. D. It’ s unreasonable.
