A healthy lifestyle is very important for everyone. It includes good eating habits, enough sleep, and regular exercise.
Good eating habits are the basis of a healthy lifestyle. We should eat a balanced diet, which includes plenty of fruits, vegetables, whole grains, and lean proteins. We should also limit our intake of junk food, such as hamburgers, fries, and soda. These foods are high in calories, fat, and sugar, which can lead to health problems like obesity and diabetes.
Getting enough sleep is also crucial. Most adults need 7 - 9 hours of sleep per night. During sleep, our bodies repair and rejuvenate themselves. Lack of sleep can affect our mood, memory, and physical health.
Regular exercise is another key part of a healthy lifestyle. It can help us maintain a healthy weight, reduce the risk of chronic diseases, and improve our mental health. We can choose the exercise that we enjoy, such as walking, jogging, yoga, or cycling.

六、阅读理解（三）
阅读下面短文，根据短文内容回答问题。
Morning exercise is a great way to start your day. It has many benefits for both your physical and mental health.
First, morning exercise can boost your energy levels. When you exercise in the morning, your body releases endorphins, which are natural mood - boosters. These endorphins can make you feel more energetic and positive throughout the day.
Second, morning exercise can improve your metabolism. By getting your body moving early in the day, you can increase your metabolic rate, which helps you burn more calories throughout the day. This can be especially helpful if you are trying to lose weight or maintain a healthy weight.
Third, morning exercise can improve your sleep quality. Exercising in the morning can help regulate your body's internal clock, making it easier for you to fall asleep at night and get a better night's rest.
Fourth, morning exercise can reduce stress. When you exercise, your body releases stress - reducing hormones, which can help you feel more relaxed and less anxious.
In conclusion, if you want to improve your health and well - being, try starting your day with some morning exercise. It doesn't have to be a long or intense workout. Even a short walk or a few minutes of stretching can make a big difference.
