First, plants can make their own food. They use sunlight, water from their roots, and carbon dioxide from the air. This is called photosynthesis (光合作用). No other living things can do this—how cool is that? Second, seeds are like magic "little packages". A small sunflower seed can grow into a tall plant with big yellow flowers. When a seed gets enough water and warmth, it sprouts and grows roots first. The roots go deep into the soil to get water and nutrients. Third, plants give us many useful things. We eat fruits, vegetables and grains from plants. We also get oil from oil-bearing plants like peanuts and soybeans. This cooking oil helps us make delicious food. Some plants even help clean the air and keep the soil from washing away. Finally, you might see a row of trees along the street. They not only look beautiful but also give us shade. Plants are our good friends—we should love and protect them. 问答题： 1、What do plants need to make their own food? They need sunlight, water and carbon dioxide. 2、What does a seed need to sprout? It needs enough water and warmth. 3、Name two useful things we get from plants. Fruits, vegetables, grains, cooking oil (任选两种即可). 判断题（对的打 “√”，错的打 “×”） 1、Only plants can make their own food.
