请勿抽烟 No Smoking
禁止通行 No Passing
勿折花木 Don't Pick The Flowers
请勿践踏草坪 Don't Step On The Grass.

No Smoking
No Passing
Don't Pick The Flowers
Don't Step On The Grass
由于是标语,所以各个单词首字母要大写

楼上的错了，不要吸烟是"No smoking"或者"Don't smoke"

Do not smoke
Do not discount flowers
No thoroughfare
Do not trample on the lawn

希望能帮的上你!
