Q29:

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

the answer is e

d为什么不对呢？

an effort for 15 years that has subjected the .... that 阴有单复数的关系，可以跳跃修饰。

15年表持续时间，用现在完成时，不对吗？

Like LES mentioned, E is better than D.

In addition, effort to subject 表明了目的， 而 D 不存在这一层意思。

a 15-year effort 中，15-year 是复合名词作adj. 用，中心词是 effort

15 years effort 中，强调 15 years 表明时间之久，并非突出 effort

ocean 在 E 中应该是笔误。

a 15-year effort 和 15 years effort 到底有没有区别，另外E中 ocean莫名其妙的改成了单数

我也想选D

偶觉得E比D简洁，

另D改变原句时态，在美语中for + 时间段既可以用于一般过去时，又可以用于现在完成时。

effort to do sth. 是固定用法。
