分析 困难比他们预料的要多,他们不可能提前完成这个项目.
解答 答案:B
题干中前后句子用逗号分隔,没有连接词,说明不是复合句;前面的句子中要用非谓语动词,构成独立主格结构.独立主格结构是由:名词(代词)+现在分词(过去分词;形容词;副词;不定式;名词;介词短语等)来构成.本题是比较特殊的there be结构的独立主格形式,这里面的there充当了名词的功能.故选B
点评 独立主格结构是由名词或代词加上分词等构成的一种独立结构,用于修饰整个句子.独立主格结构中的名词或代词与其后的分词等构成逻辑上的主谓关系.这种结构与主句不发生句法上的联系,它的位置相当灵活,可置于主句前、主句末或主句中,常由逗号将其与主句分开.需特别注意的是,独立主格结构与主句之间不能使用任何连接词.
