The Impact of Seasonal Droughts
Droughts are prolonged periods of water scarcity, often linked to seasonal climate patterns. In Mediterranean regions, summer droughts have become more intense due to climate change, affecting both natural ecosystems and human activities.
Natural ecosystems respond to droughts by altering plant growth and animal behavior. Trees in drought-prone areas may reduce leaf size to conserve water, while animals like deer may migrate in search of water. These adaptations help species survive, but prolonged droughts can lead to ecosystem collapse.
Agriculture is severely impacted by droughts. Crops fail, leading to food shortages and economic losses. In California, the 2012-2016 drought cost the agriculture industry over $3 billion. Rural communities dependent on farming suffer most, as water restrictions force farmers to abandon fields.
Water management is crucial during droughts. Governments implement water rationing and promote drought-resistant crops. Individuals can conserve water by reducing usage at home. However, addressing climate change remains the key to preventing future drought crises.
(1)、What is a drought?A、A period of heavy rain. B、A long period of water scarcity. C、A type of storm. D、A seasonal wind.(2)、How do trees adapt to droughts?A、By growing larger leaves. B、By reducing leaf size. C、By producing more fruit. D、By dying quickly.(3)、What was the economic impact of California's drought?A、3 million loss. B、30 billion loss. C、3 billion loss. D、300 million loss.(4)、What is the key to preventing droughts?A、Water rationing. B、Drought-resistant crops. C、Addressing climate change. D、Building dams.(5)、What's the main idea of the passage?A、The causes of droughts. B、The impact of droughts and solutions. C、Animal migration during droughts. D、Water management in cities. -
