题目内容

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

In the summer holiday，we travelled to Qingdao and paid visit to my uncle there. It's a long and bored journey. But the moment I arrived, I fall in love with the city. It's such beautiful a city that I can hardly find any word to describe it. The streets are cleaning and the sky is blue. If you walk along the coast，you can feel the wind to blowing on your face. The sea is vast and sometimes you can find a boat or a ship. You may also do some fishing as far as it is permitted. Moreover，I think the driver there drive too fast in the street. You should be careless when crossing the street.

Olympic gold medalist Morolake Akinosun walked through the halls of her high school in Illinois in the US, surprised at how little had changed at her old high school other than the green color on the walls.

Akinosun won her medal with the 400-meter relay team at the Olympic Games in Rio de Janeiro this summer. Her return to her high school recently included a chance for the young woman to tell what she’s learned since running track for Wsubonsie more than fours year ago.

Her first piece of advice to the crowd of students was asking them to listen to their parents. “ They see things you can't see,” she said. “ In high school I thought I was on the top of the world.”

In Akinosun’s case, her parents encouraged her to consider going to the University of Illinois, which at the time had a team that was coached by Olympic medal winner Tonja Buford-Bailey. “ I wouldn’t be where I am today without my parents,” she said.

Her parents saw Buford-Bailey as a good fit to coach their daughter, something Akinosun said she didn’t understand at the time. It didn’t take long, however, for her to see they were right and she ended up following Buford-Bailey to the University of Texas at Austin when the coach took a job there. Akinosun admitted it was three years before she told her parents they were right.

Becoming an excellent athlete who can take part in the Olympics needs serious dedication. She says her success came from viewing herself as an athlete-student instead of a student-athlete.

“I always put track and field first, and then comes school,” Akinosun said. A social life comes last.“It’s about sacrifices(牺牲). You can’t be on the track team unless you’re chosen,” she added.

Making athletics the most important thing in her life meant devoting her time and energy fully, no matter how she might feel on a given day. “ I never missed a training session (环节) in my four years in college,” she said. “It’s my job; it’s what I do. Think about that when you want to sleep in.”

1.Which of the following statements is TRUE about Akinosun according to the article?

A. She was a big fan of Buford-Bailey in high school.

B. She make up her mind to win Olympic gold medals in high school.

C. She still doesn’t want to admit that her parents helped her a lot.

D. She is thankful to her parents for finding her the right coach.

2.According to Akinosun, she became a successful athlete because ______.

A. she had great confidence in herself.

B. she always put training before anything else.

C. she was pushed by her coach to train hard.

D. she could keep a good balance between school and training.

3.The underlined word “dedication” in Paragraph 6 is closest in meaning to ______.

A. a strong desire B. knowing oneself

C. a clear purpose D. devoting her time and energy fully

4.What’s the best title of the passage?

A. How Akinosun spent her high school years.

B. The story of Akinosun’s success.

C. Being an athlete is not easy.

D. Akinosun’s advice to her schoolmates.
