Were it not for the fusion-powered heat and radiation that rush from its core, instead its own weight would cause a star to collapse.

A    instead its own weight would cause a star to collapse
B     instead a star would have collapsed under its own weight
C     a star would have to be collapsing under its own weight
D    a star would collapse under its own weight

E    its own weight would have caused a star’s collapse

哪位好心人士，帮忙解释下，我选的是E，答案是D。 这道题一点头绪都没有

虚拟语气
if +过去时， 主句用would、could

请教NN，B中的instead是怎么个错法？

Were it not （原语序：if it were not）for the fusion-powered heat and radiation that rush from its core, instead its own weight would cause a star to collapse.



A.instead its own weight would cause a star to collapse

B.instead a star would have collapsed under its own weight

C.a star would have to be collapsing under its own weight

D.a starwould collapse under its own weight（would对应if it were的虚拟语气的过去和过去将来时态；star collapse主动优于被动）

E.its own weight would have caused a star’s collapse（it指代不明，逻辑上就是a star自己，但是语法上翻译出来就是：它自己的重量可能会导致一个星体爆炸。could have的虚拟语气对应于if it had been，错；cause a star’s collapse不好，cause a star to collapse更好）

这道题我之前看到一个大牛的解释就顿悟了：Were it not for不是一般的倒装，而是If it were not for的意思。

好像有点道理

E似乎意思不大对……感觉像是把别的star collapse掉一样……
