不认同解析中 promoting 表伴随,应该是做结果状语,因为 bird 不能 promoting,fell 和 promote也不能同时发生
关于D选项的疑问,RON大神的解释是说,D选项中的which修饰前面的highlands,第一个是meaning不对,第二是highlands是复数,动词的单复数也错了。但是RON有一期课讲“which”的用法时好像说过,which是可以修饰the NOUN + PRE PHRASE that immediately precedes the comma。那D选项中为什么不能理解成which是修饰strategic position(noun)+ at the foot of the highland (pre phrase)呢?
为什么是HAD不是DID?就算是时态变换不也应该是DO换成DID吗?真的实在搞不懂GMAT的套路。。。
主谓一致,杀ABC
果因
Next we might consider which form of the verb "create" is appropriate, the verb "create," the present participle "creating," or the infinitive "to create." A verb-form split usually signals either an idiom problem or a problem with parallelism, but not in this case. Rather, neither C nor D captures the original meaning. Answer C: A present participle (-ing word) immediately preceded by a noun (no comma separating them) attributes action to that noun. So C means that "an individual" creates responses. Answer D: Here, "to create" suggests that the goal of producing emotional reactions is to create physiological responses.
