请教: 大全 #31

为什么是D? 这道题如果一定要用depending on its mass应该怎么改?

多谢!

大全31.        A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.

(A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.

(B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole.

(C) After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole.

(D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.

(E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.

答案是D

E：中后面的IT有歧义，是指MASS还是STAR不清晰。

C。不可以用IF，而应用whether,同时a star’s mass也不对，应用OF结构，After passing through a red giant stage也不可以修mass

B。逻辑主语有问题，不应是STAR而是MASScompress，同时 After passing through a red giant stage, depending on its mass的结构也不对

A。同时都有上面的问题!

所以选D
