Part One托福写作素材模板:智慧城市的兴起
素材段落
With the widespread application of sophisticated information and communication technologies, the concept of creating a ‘smart city’ has been proposed as the ultimate goal that large cities would seek in their future development. A ‘smart city’ could largely improve the quality of life and the performance of urban services. For example, it has brought local residents a more efficacious and user-friendly public transportation system. In Barcelona, a new bus network has been designed to utilize vertical, horizontal and diagonal routes with a number of interchanges, based on the analysis of the most common traffic flows. Also, when smart traffic lights are set up and traffic management software is installed, the number of green lights on each street has been optimized to avoid traffic congestion as well as to allow ambulances to reach incidents without any delay.

Part Two托福写作素材模板:有机食品和健康
素材段落
Organic food is much healthier than conventional food due to its higher levels of antioxidants and lower levels of pesticides. Antioxidants have been linked to a lower risk of cancer and other diseases in humans. Scientists have discovered that organic food contains an average of 17% more antioxidants than conventional food. The reason for this is because plants naturally produce antioxidants to defend themselves against pests and diseases. When pesticides are applied to plants, they lose their need to generateantioxidants for their own defenses. It is also important to note that pesticide residues are found to be three to four times more likely on conventional food as compared to organic food. This data is based on a recent study conducted by Dr. Benbrook from the Center for Sustaining Agriculture and Natural Resources at Washington State University. Pesticide residues can cause dizziness and headaches (as their acute effects) and neurological problems and birth defects (as their long-term effects).
