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 OG解释中说D中“beginning the phrase with as is incorrect”,我不理解由as开始的短语错是什么意思。是特指这道题,还是普遍真理啊? 还有说E“to protect cannot act as an adjective modifying items”,为啥就不能修饰呢? 这题实在想不通,请各位帮忙。 |
