1.Face covered in sweat, he might be walkingthrough the field, carefully checking hiscrops before deciding what needs to be done.（P16, line 2）
翻译：他满脸大汗，可能正在田间走动，仔细检查他的作物，然后决定需要做什么。
（1）句中Face covered in sweat为独立主格结构作状语。独立主格结构的逻辑主语Face与主句的主语he不一致，它独立存在。
（2）该结构在句中一般作状语，表示时间、条件、原因、伴随状况等。常见的独立主格结构：
Eg: There being no people,we should go home.
