1. A star wil1 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, 不解, B又错在哪里?

3. In terms of physics, the characteristic
feature of the roller coaster is that the cars' potential energy, gained through their
being lifted by a chain drive through the Earth's gravity to the top of the first drop, has been
converted to kinetic energy by the time the ride ends.
(A) cars' potential energy, gained through their being lifted by a chain drive
(B) cars' potential energy, a gain achieved as they are lifted by a chain drive
(C) potential energy from the cars' being lifted by a chain drive
(D) potential energy of the cars, gained as a chain drive lifts them
(E) potential energy gained by the cars, being achieved while a chain drive
lifts them 答案是D, 不解!
