Plants growing and changing
新考法 人与自然:动物与植物 难度:★★★ 建议用时:6分钟
春天来了,万物复苏,植物也变得生机勃勃。你知道植物是如何变得生机勃勃的吗？它们的生长又需要怎样的环境呢？我们来一探究竟吧！
Plants need things to grow healthy and strong. They need water, air and sunlight. Plants get nutrients from the soil. They use them to help make the “food” that they need to grow. The soil holds the plant in place. Seeds form inside the plant's flowers. These seeds can grow into new plants.
Plants and the environment A change in the environment can change how a plant grows. Plants grow well with the right amount of sunlight. Plants that do not get the right amount of water and sunlight may not grow well.
More ways plants change Wind can change how a plant grows. The beach morning glory plant's flowers lie close to the ground. They stay safe from the wind.
