题目分析:
本题将多个小句进行了主从句的变换,着重考查考生对于主从句的把握。

选项分析:

A选项:被命名为a mythological nymph(having been named for a mythological nymph who cared for the infant Jupiter)在本选项中是伴随状语,“Ida被发现(the asteroid named Ida was discovered in 1884)”是主句。这是不正确的。依据图形背景原则,“被命名为a mythological nymph”不能是“Ida先被发现”的背景。因为,在逻辑上,应是Ida先被发现,然后才是被命名,两者不具有时间轴上谁大于谁的问题。

B选项:Correct. 本选项在语法和逻辑上均是正确的。

C选项:本选项没有谓语动词(discovered和named在本选项中均是过去分词,身前需要加be动词(系动词)才能成为谓语动词(被动语态))。

D选项:句末的to do不定式(to orbit the Sun between Mars and Jupiter)在本选项中是asteroids的后置定语。其考查了“不定式和从句的区别”。用之于本题,主句“Ida是在小行星带中的”事件的发生对“小行星带环绕太阳”这个事件发生与否没有直接影响(你不能说,ida在小行星带后,触发了这些小行星带环绕太阳吧?这两个事件均是客观事实,不存在谁触发谁)。因此,只能用that orbit the Sun between Mars and Jupiter这个从句的形式。

E选项:to orbit不能做asteriods的定语错误同(D)。另外,本选项中的an asteroid discovered in 1884 和which was named for a mythological nymph who cared for the infant Jupiter不平行。这是因为,前者是同位语,后者是定语,两者的功能不同(如果两者都是定语,则可以平行),所以不能用and连接。

如果你有什么疑问,后者想要交流讨论的,可以留言!
