Paraphrasing Recognition Strategies

1. Scientific and Technical Paraphrasing

Common Paraphrasing Patterns:

• Process synonyms: "produces" → "generates," "creates," "yields"
• Component terms: "parts" → "elements," "components," "sections"
• Movement vocabulary: "flows" → "moves," "travels," "circulates"
• Structural descriptions: "attached to" → "connected with," "linked to," "joined by"

Advanced Paraphrasing Examples:

• Diagram: "Input chamber" | Text: "Initial reception area"
• Diagram: "Filtration system" | Text: "Purification mechanism"
• Diagram: "Output valve" | Text: "Release mechanism"
• Diagram: "Control panel" | Text: "Monitoring interface"

2. Process Description Paraphrasing

Sequential Indicators:

• Diagram: "Stage 1" | Text: "Initial phase," "First step," "Primary stage"
• Diagram: "Final product" | Text: "End result," "Ultimate outcome," "Finished item"
• Diagram: "Intermediate step" | Text: "Middle phase," "Transitional stage," "Secondary process"

Functional Descriptions:

Practice Exercise: Solar Panel System

Sample Diagram Description:

"The diagram shows a residential solar energy system with labeled components requiring completion. The system includes solar panels, an inverter, a battery storage unit, and connections to both the electrical grid and household appliances."

Passage Extract:

"Modern photovoltaic systems convert sunlight into electrical energy through sophisticated semiconductor technology. The solar cells mounted on rooftops capture photons and generate direct current electricity. This DC power must be transformed by a power conversion device into alternating current suitable for household use. Excess energy is stored in rechargeable units that provide electricity during periods of low sunlight. The system connects to the municipal power network to sell surplus energy and draw additional power when needed. Household electrical devices receive clean energy through this integrated system, reducing dependence on traditional fossil fuel sources."

Practice Exercise: Water Treatment Plant

Complex Diagram Scenario:

"A municipal water treatment facility processes raw water through multiple purification stages before distribution to residential areas."

Advanced Passage Extract:

"Municipal water purification facilities employ sophisticated multi-stage treatment processes to ensure safe drinking water delivery. Raw water enters through intake pipes from natural sources such as rivers or reservoirs. The preliminary screening apparatus removes large debris, leaves, and floating materials that could damage downstream equipment. Water then flows into sedimentation basins where gravity allows heavier particles to settle to the bottom, forming sludge layers that are periodically removed. Chemical treatment tanks introduce coagulation agents that bind smaller particles together, improving removal efficiency. The rapid filtration system passes water through layers of sand, gravel, and activated carbon to remove remaining suspended materials and organic compounds. Disinfection chambers use chlorine or ultraviolet light to eliminate harmful bacteria and viruses, ensuring microbiological safety. Finally, distribution pipelines carry treated water through underground networks to homes and businesses throughout the municipal area."

Advanced Practice Questions:

1. Raw water entry point: _______
2. Large debris removal system: _______
