Exercise 11. Match each item on the left with an item on the right to develop the idea and describe the possible future uses of drones.
| 1. delivering food 2. expanding Internet access 3. humanitarian work 4. archaeology 5. farming 6. drone journalism 7. medicine 8. education 9. military purposes 10. space exploration | a. drones will be reducing labor and operational costs, radio-controlled drones can be used to spray crops with fertilizers and pesticides; b. drones equipped with heat-sensing cameras will provide thermal images of remote areas, such as desert, and will enable the researchers to see beneath the ground and locate the buried ancient structures; c. supplying remote villages with food or water, probably with gas or other important things; d. usage of high-altitude ultra-lightweight solar-powered drones as part of a network of linked satellites, drones and lasers to beam Internet to remote communities from the sky; these will fly high above commercial air traffic and will remain aloft for up to five years; e. delivering vaccines and other critical medical supplies to remote locations inaccessible by roads in the developing world; f. serving as weapons platforms for combat operations; g. sending unmanned spaceships with different equipment on board; h. collecting information in the form of capturing real-time footage and broadcasting it on the radio or the television; i. enabling scientific studies of areas difficult to access; serving as models for flying in safe environment as preparation for real research in the open field; j. an innovative service to deliver food from restaurants avoiding traffic jams. |

EXPLORING GRAMMAR
Exercise 14. Find Participles 2 in these examples:
- A drone, in a technological context, is an unmanned aircraft.
- The aircrafts may fly autonomously through software-controlled flight plans in their embedded systems working in conjunction with onboard sensors and GPS.
- Drones now used for civilian purposes range from search and rescue, surveillance, traffic monitoring, weather monitoring and firefighting to personal drones.
- During a research trip to Guatemala, a team of volcanologists and engineers used customized drones (also known as unmanned aerial vehicles, or UAVs).
- Researchers used drones equipped with a range of sensors.
|
|
|
- The drones also had thermal and visual cameras attached to observe the volcanic activity.
- The drone has a motor in the center surrounded by a flexible geodesic sphere.
- It's designed to work in dangerous or disaster-stricken areas.
Remember the forms of Participles:
| Active | Passive | |
| Present | controlling | being controlled |
| Past | - | controlled |
| Perfect | having controlled | having been controlled |
