bonus, enormous, boast, give rise to, integration, ideal, real time, put … to good use
Vertical farming uses urban spaces for the highest possible crop yields. It promotes soil-free systems, which require no pesticides, so the farming method is eco-friendly. As an added (3) __________, farmers can grow crops all year round in this artificial farming environment without worrying about abnormal weather, which often leads to crop losses. (4) __________for urban areas, vertical farming has taken off in many countries, where the view of buildings “growing” green leaves provides a refreshing contrast to a concrete jungle of offices and flats.

For instance, Singapore, with a population of about six million and an area of only about 720 square kilometres, (5) _________________ many vertical farming zones.
However, there are some obstacles to overcome if vertical farming is to have a greater impact. A major one is meeting the electricity demands of such projects. Vertical farms are highly controlled environments, which are monitored in (6) _________________ and require large amounts of energy.

n. 障碍，阻碍；障碍物，绊脚石
bonus, enormous, boast, give rise to, integration, ideal, real time, put … to good use
Consequently, there has been the push for renewable energy sources, as they would not increase the high levels of pollution normally found in urban areas.
As the benefits of vertical farming appear to be (7) _________________, it may enjoy greater popularity in countries where agricultural land is scarce. Hopefully, the (8) _________________ of technology and innovation may be one way of overcoming the practical problems of crop farming.
