In a partnership with the 5 Gyres Institute, Trash Free Maryland took to the Chesapeake Bay in November to study the presence of micropiastics in the water. Setting out from Deale, Md., the research team collected seven samples by dragging a trawl (拖网) for an hour at a time. The trawl was fitted with a cone-shaped (锥形的) net, whose holes measure 330 microns (微米) wide, about the width of two to three strands of human hair. Water flows through the main opening and the fine mesh (网眼) of net ensures anything suspended in the water is trapped behind.
In seven samples, the net picked up algae (海藻) trash, foam and plastic. According to the 5 Gyres Institute representative, the first sample collected contained almost 10 times the amount of plastic than would be collected in a typical ocean sample. The plastic found in the Chesapeake Bay samples included bits of bags, sheeting, fishing line and microbeads, which are small plastic scrubbers found in face wash, toothpaste and cleaning products. Microbeads in particular are a major source of microplastics pollution worldwide. They are small enough to bypass water treatment systems’ filters (过滤器) and end up in waterways. Scientists warn that chemicals and toxins (毒素) absorbed by microbeads and other microplastics could be passed on to organisms who mistake them for food and eat them, and could then be passed up higher and higher on the food chain, eventually reaching humans.
1.What is the second paragraph mainly about?
A. The description of the trawl.
B. The basic data of the water samples.
C. The process of collecting water samples.
D. The introduction of Trash Free Maryland.
2.What does the underlined word “They” in the last paragraph refer to?
A. Bits of bags. B. Chemicals.
C. Microbeads. D. Micropiastics.
3.How does the author prove plastics pollution can be harmful to people’s health?
A. By analyzing the data. B. By making comparisons.
C. By giving some examples. D. By referring to scientists views.
4.What’s the author’s purpose in writing this passage?
A. To explain some new scientific terms to people.
B. To let people learn more about plastics pollution.
C. To urge governments to make environmental laws.
D. To tell people some new findings in scientific research.

A conflict at work is common. If you can avoid conflict, it means you will win what you want regardless of what the other person wants. Since the potential issue has not been removed, it will simply reappear later. Here are the necessary steps to effectively get rid of conflicts at work.
★Be aware of the fact that some conflicts are unavoidable at work. On numerous occasions, conflict and disagreement are likely to happen. But when a conflict happens it's not the end of the world. On the contrary, it can be the beginning of an interesting learning process. Conflicts mean that people care enough to disagree strongly. The trick is not to allow the conflict to go on forever.
★ Deal with conflicts sooner rather than later. Solve a conflict when it starts, as it only gets worse with time going by. Conflicts at work arise not from something that was said, but from something that wasn't said! Everyone's waiting for the other to admit he's wrong and gets more unpleasant after the conflict has lasted a while. It's essential to interrupt the "waiting game" before it gets to that point.
★ Ask nicely. If somebody has done something that made you angry, or if you don't understand their viewpoint or actions, simply asking nicely about it can make a world of difference. Never assume that people do what they do to annoy or hurt you. Sometimes there's a good reason why that person does what he or she does, and a potential conflict disappear right there. Do remember to make an inquiry, not an accusation of any sort.
★ Appreciate. Praise the other part in the conflict. Tell them why it's worth it to you to solve the conflict. This can be difficult as few people find it easy to praise and appreciate a person they disagree strongly with, but it's a great way to move forward.
Topic | How to 1. conflicts at work |
Reason | Conflicts won't 2. if not dealt with |
3. on handling conflicts | ● Don't be afraid of conflicts which can happen in many 4. and try to resolve a conflict soon or it will get 5. ●Interrupt the "waiting game" and try to admit your 6. actively. ● Don’t imagine people do something to make you 7. on purpose. ● Remember not to 8. others, but ask them nicely about what they do, which may make a difference. ● Try to appreciate the other part in the conflict although it is 9. to do so. |
10. | If you learn to do with conflicts, you'll work in joy. |

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
