    It’s getting warmer and the grass is greener. How fine it is to relax on the grass. But signs such as “keep off the grass(远离草坪)” in china always make me afraid. In the UK, people can relax in the open air or in the parks at any time.

If it’s a sunny day, people will just sit on the grass and feel the sun’s warmth. Families enjoy spending their weekends on the grass. There, families can bring something to eat or drink and play cards with family members or friends; children can play chess and tell each other jokes.

Also, in most schools, grass fields are like a soft study desk for students. They can enjoy reading books and learn in the green environment(环境). They also talk, laugh, listen to music and play games on the grass.

In some parks, there are many kinds of green grass for people to relax and play sports on. Be smart to find the good one, and you may feel yourself sitting in the middle of a soccer game.

However, there is one rule when you enjoy the green grass: keep it clean!
