答案是D中的each contributing是什么意思 修饰的是哪个词 拜托GGMM们了 很急!!!
我来试着解答一下。
each contributing 是独立主格结构。
each是指 each planet, 这里还原回来就是each ( is ) contributing.
独立主格结构做伴随状语:
独立主格结构是由一个名词或代词(作为该短语结构的逻辑主语),
加上一个分词、形容词、副词、
动词不定式或介词短语(作为该短语结构的逻辑谓语)构成.
独立主格结构放在句首或句尾,起状
语作用,表伴随原因﹑条件﹑状态等
1)一般独立主格,与主句形成松散的逻辑关系,形式为:
n.+ n.; n. + -ed/ing 形式; n. + 介词短语;n. +形容词短语
2)with 型独立主格,与主句形成紧密的逻辑联系,形式为:
由“with
+宾语+宾补”构成的复合结构,在句中可作状语,表示伴随。这一结构中的宾语补足语
可由现在分词、过去分词、形容词、副词或介词短语等来充当
Visitors to the park have often looked into the leafy canopy and seen monkeys sleeping on the
branches, with arms and legs hanging like socks on a clothesline.
3)each 型独立主格,强调句尾名词,形式为:
句子 + 复数名词结尾, each + 介词短语/形容词短语/-ed 形式/-ing 形式。piggyuu 发表于 2009-10-3 06:09
