这里面C和E的语义是有区别的。
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 两个that限定性定语从句表示的是监测什么样的地震波呢 监测符合这两个条件的地震波 把most raidly...用that从句的话 表示值检测在cold region传的快的地震波,实际上这并不是OA的意思 OA的意思是监测所有的地震波 |
