标题: prep 43

Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar

radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing

over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons

(CFC's).

(A) acting as a global thermostat and thus keeping Earth from either burning up or freezing over,

they also accelerate

(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over,

while also accelerating

also accelerating

(D) they act as a global thermostat that thus keeps Earth either from burning up or freezing over,

even though it also accelerates

(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but

they also accelerate
ans:a
當時排除a 是認為acting as a global thermostat and thus keeping Earth from either burning up or freezing over 會往前修飾 radiation
Q:是否是因為ving結構優先做定語修飾前面的n 但不合邏輯時即作狀語修是整個句子
所以此處修飾整句阿?
