有没有一种简单的方法可以在每个句子之间添加四个空行。
例如这一段：
This combination of vitamins and selected minerals is used to prevent or treat vitamin
deficiency due to poor eating habits, problems that affect the body's ability to absorb nutrition from food, or increased need for vitamins and minerals due to stress
or illness. Vitamins are needed for the body to function well.
This vitamin/mineral combination contains high levels of B vitamins (e.g., folic acid,
niacin, B-1, B-2, B-6, and B-12) and vitamin C. It also contains other vitamins (A, D, and E) and minerals such as zinc. This medication does not contain iron and has only a
small amount of calcium. Therefore, it should not be used to treat "iron-poor" blood
(anemia) or to prevent osteoporosis.
