　　1．Covering　grasslands与cover之间是逻辑上的主谓关系，且cover所表示的动作与谓语动作同时发生，故填Covering。

　　2．are known　由语境可知，设空处是对一般情况的描述，应用一般现在时，又因为grasslands与know之间是被动关系，故填are known。

　　3．on/upon　depend on/upon意为"取决于"。

　　4．which　设空处引导非限制性定语从句，补充说明The Great Plains，且在从句中作主语，故填which。

　　5．To make　由语境可知，当地牧场与环保小组合作是为了使他们的生意更成功，故填To make。

　　6．environmental　设空处作定语修饰groups，表示"有关环境的"，故填environmental。

7．Compared　compare与these groups之间是逻辑上的动宾关系，且compare所表示的动作已完成，故填Compared。
