The spectacular disintegration of a comet last year in full view of ground- and space-based telescopes provided new insights into how comets form and may thus force a rethinking of the role of comets in the delivery of organic compounds to the evolving Earth.

 

A.      The spectacular disintegration of a comet last year in full view of ground- and space-based telescopes provided new insights into how comets form and may thus force

B.      The spectacular disintegration of a comet last year in full view of ground- as well as space-based telescopes, provided new insights into how comets form and thus possibly forcing

C.      When a comet's spectacular disintegration occurred in full view of ground- and space-based telescopes last year, it provided new insights into how comets form and thus may possibly force

D.      Last year, in full view of ground- and space-based telescopes, a comet's spectacular disintegration provided new insights into how comets form and thus possibly forcing

E.       Last year, in full view of ground- as well as space-based telescopes, the spectacular disintegration of a comet has provided new insights into how comets form and may thus force

thus的用法？？thx

yuminjia

thus就是个副词 还是主要看provided...and may thus force平行吧

queenie0308

Why not D???

yuminjia

D中的provided和forcing不平行

thus我觉得就是个副词 不是特别考虑的

可为什么过去式和现在时并列呢?

mars_cheung

我也栽在这上面了，如果这里用了 forced 估计大家都懂得怎么选。ETS 就是狠啊
这里应该是 provided 和 may force 并列，may 这里不是现在时，而是表示可能性（情态动词时态性不强）

5） 情态助动词的“时”的形式并不是时间区别的主要标志。在不少场合，情态助动词的现在时和过去时形式都可以表示现在、过去或将来时间：

因此我觉得可以认为 may force 是表示过去的一种可能性，请NN指正

嗯嗯。。。不过xdf笔记里说may大多是错的。。。

不是may，是maybe一定错
