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
我选的D ,答案是 E, 我问的问题是:a 15-year effort 和 an effort for 15 years 有什么区别?另外想听听 大家对D 和E 的想法。 谢谢~
我觉得是 an effort for 15 years that has subjected the interactions 这个有指代不清的嫌疑,15 years放在that前面会使得that has subjected the interactions修饰对象模糊,不知道是effort 还是 years。 而a 15-year effort to subject the interactions就没有这个问题,所以选E。
