科技论文讲求简明扼要,用词尽量避免生涩但要使用专业术语,我写论文时总是做不到简明,叙述是总会用复杂句,所以你就仅当参考吧
Acid rain refers to atmospheric precipitation like rain ,snow and other forms of precipitation that has a pH of less than 5.6, and it is a manifestation of air pollution.Acid rain can impact upon human environment in various ways.As it falls in the river or the lake,it can prevent the aquatic organism from growing,worse still,some even die out. what's more,acid rain is also the prime criminal of soil acidification,which will lead to poor soil and a reduction in production.In addition,acid rain can also erode building materials.
