Twenty-two feet long and 10 feet in diameter, the AM-1 is one of the many 【new satellites that is a part of 15 years effort of subjecting the interactions of Earth’s atmosphere, oceans, and land surfaces】 to detailed scrutiny from space.
A. satellites that is a part of 15 years effort of subjecting the interactions of Earth’s atmosphere, oceans, and land surfaces
B. satellites, which is a part of a 15-year effort to subject how Earth’s atmosphere, oceans, and land surfaces interact
C. satellites, part of 15 years effort of subjecting how Earth’s atmosphere, oceans, and land surfaces are interacting
D. satellites that are part of an effort for 15 years that has subjected the interactions of Earth’s atmosphere, oceans, and land surfaces
E. satellites that are part of a 15-year effort to subject the interactions of Earth’s atmosphere, ocean, and land surfaces
应该是选E吧？D中：
1、“for 15years”的修饰对象有歧义，可以理解为 “ an effort for 15 years”也可以理解为satellite是effort的一部分有15年了。
2、剧中没有什么标志表明应该用现在完成时呢~
3、effort to do sth是固定搭配。
4、连着出现两个that的表达有点诡异，not idiomatic。作者: trtwarrior 时间: 2011-4-27 21:44
