单选题
Shining down out of the blue sky, ______. A. the sun burnt their pale skins B. the sun burning their pale skins C. they were burnt by the fierce sun D. their pale skins were burnt by the sun
【正确答案】
A
【答案解析】[解析] shining down out of the blue sky为分词短语作状语。分词短语作状语可以置于句首或句末，表示方式、原因、目的、伴随状况等。做这样的题时仍需注意分词与句子主语的逻辑关系，现在分词表示动作是由句子主语发出的；过去分词表示主语是受动者。由于本句句首先有了现在分词短语，因此要选主语是分词施动者的句子，而B项不是完整的句子，只有A项是可选答案。
