题目分析:
略
选项分析:
A选项:过去分词短语found only in the Western Hemisphere和现在分词短语 surviving through extremes of climate均做主句的伴随状语,在平行方面没有问题(详见功能平行)。但是,由于伴随状语的主语和其主句主语相同,在本选项中即,find和survive的主语均为hummingbirds’range,这在逻辑上是不正确的。被发现和存活的都是鸟,而不是鸟的范围。
B选项:Correct. 本选项在语法和逻辑上均是正确的。句末出现的their range extending from Alaska to Tierra del Fuego, from sea-level rain forests to the edges of Andean snowfields and ice fields at altitudes of 15,000 feet是独立主格结构。
C选项:本选项缺少谓语动词。
D选项:本选项主句具有两个主语,在语法上是不正确的,即:
Hummingbirds, found only in the Western Hemisphere and surviving through extremes of climate, their range extends
划线部分为插入语,extends拥有两个主语(两个黑体字)。
E选项:本选项中found和survive之间缺少连词。
老师我看不懂b项里为什么末尾是独立主格结构。
umm...这个问题有点模糊。
从结构上来看,(with) + 名词 + doing/-ed都可以算作独立主格结构。
从意思上看,本质上独立主格结构是一个状语从句。意思上这个独立主格在解释前面survive这个动作的范围。通俗说,就是在哪里“幸存”。
谢谢老师,我还是学和看都太粗浅,应该精细地学课程。您这么一说,我才会想到这些点课程和网站上都有讲过,自己很难举一反三。
哈哈,这很正常啦~只有不断的重复,才能强化嘛~
