范文：

Linda plays sports outside every day. It's good for her eyes. She never plays on a phone. She doesn't watch TV for a long time. They have healthy habits.

【分析】首先明确写作任务：介绍Linda家人的健康习惯，需运用题目给出的“积木式写句子”方法（在中心词基础上逐层丰富句子含义），结合范文的“总起-分述-总结”结构展开。第一步总起说明Linda有幸福家庭；第二步分别介绍爸爸、妈妈、Linda的健康习惯，用逐层丰富的句子补充细节；第三步总结家人都有健康习惯，确保内容具体符合要求。

She doesn't watch TV for a long time.；最后总结：They have healthy habits.
【答案】Linda has a happy family. Her father has a healthy habit. He runs every day. He likes exercising. It makes him strong. Her mother drinks enough water every day. It's good for her.
