To map Earth's interior, geologists use a network of seismometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.
之前有同学发个这个问题了,不过讨论的点不太一样,我又重新发一下,复制了原来那个同学的题(http://forum.chasedream.com/foru ... &highlight=OG16)
我的问题是正确选项C中的COMMA+VING修饰的ricochet是不是从句动词??如果是的话就说明句尾的Ving可以修饰从句动词,或给从句做伴随?这个纠结好久了 求助各位大神
86. To map Earth's interior, geologists use a network of seismometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.
(A) interior, most rapidly traveling through cold, dense regions and slower
(B) interior, which travel most rapidly through cold, dense regions, and more slowly
(C) interior, traveling most rapidly through cold, dense regions and more slowly
(D) interior and most rapidly travel through cold, dense regions, and slower
(E) interior and that travel most rapidly through cold, dense regions and slower
OG解释
This sentence explains in detail an activity of geologists (using seismometers to chart waves), focusing primarily on the object, seismic waves. A description of these waves is developed in a relative clause (that originate ... hotter rocks) that contains a compound verb phrase (originate ... ricochet . .). The action, ricochet, is further described in a participial phrase in which traveling ... is then further described in a comparison of travel speeds in cold and hot regions of Earth's crust.
C Correct. The modifiers are parallel and correctly positioned in relation to the verb.
