30。For members of the seventeenth-century Ashanti nation in Africa, animal-hide shields with wooden frames were essential items of military equipment, a method to protect warriors against enemy arrows and spears.

(A) a method to protect

(B) as a method protecting

(C) protecting

(D) as a protection of

(E) to protect

答案是c,og的解释；protecting properly introduces a modifying phrase revealing the purpose of the items. 就是做定语从句吧。

1. The Glass House Mountains in Queensland, Australia
, were sighted in 1770 by the English navigator Captain James Cook, by whom they were named supposedly because its sheer wet rocks glistened like glass.

(A) by whom they were named supposedly because its

(B) by whom they were named supposedly and their

(C) naming them supposedly since their

(D) who so named them supposedly because their

(E) who so named it since supposedly their

c 是错误的除了since的问题以外，分词naming不能做定语从句了，og的解释: as the object of a preposition and not the subject of the clause,james Cookdoes not work as the noun that the verbal phrase beginning with naming can describe.

请问，为什么30题分词短语可以做定语从句，1题的分词短语为什么不能做定语从句呢？

谢谢答复

30题，分词在句尾表功能结果，其逻辑主语是主句的主语。
1题，如果选分词的话，同理不能修饰前面的介词短语，所以逻辑主语出问题了。

30题主句主语不是item of military啊？这样的话，为什么og说是修饰item呢？
1题为什么不能做定语从句使用呢？

谢谢，万分感谢。

、

引用一段PREP笔记里的话，我也跟着学习了。

V-ing结构在句子中可以做状语。
如果前面是主系表结构，由于系动词是一个状态不存在“被伴随”，但是V-ing结构依然修饰的是整个主系表结构，所以后面的V-ing结构也可以被解读为修饰前面的名词成分—主语（如果宾语是名词，也一同修饰，因为主系表结构中主语和宾语所指是同一事物

21。Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.
(A) Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are
(B) Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
(C) Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
(D) Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,
(E) Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,
答案是A
OG对D项的解释: The final descriptor in present tense,now drawing conclusions....does not fit the opening clause, which is in present-prefect tense(have amassed a wealth)and seems to midify adulthood.

那还想请问，既然这里没有主系表结构，分词短语为什么也会有做定语修饰adulthood的嫌疑？因为og第一题的c项，就是我第一个问题里面，og的解释是分词短语不能做定语修饰前面这个名词的啊，这里怎么又可以做定语修饰前面的名词了呢?og解释岂不是矛盾？

求高人指点。。。

现在分词在句尾用逗号隔开，必须要注意的一点是这个结构从来都没有失去过“做定语”的功能，只是优先做状语而已，或者也可以说是优先修饰到前面主句的主语和谓语头上去。
而如果前面主句的谓语是完成时态，那么既然已经完成了，drawing就无法再做其的伴随，所以只剩下做定语的功能。So OG says that.
