一道SAT 语法IS题.The price of gold has been influenced

本句中The price of gold has been influenced（黄金价格已经受到影响）是结果,后面的by continued inflation 和从句because people have lost faith in the dollar 都是受影响的原因.如果用两个简单句把它们单列出来,无疑是可以成立的： The price of gold has been influenced by continued inflation. The price of gold has been influenced because people have lost faith in the dollar. 或者把两个句子用 and 连接成平行结构的并列句,即“主谓结构 + 原因状语”,也是正确的： The price of gold has been influenced by continued inflation and it has been influenced because people have lost faith in the dollar. 但是本句却把by表示原因的介词短语和because 引导的原因状语从句并列,显然不是平行结构.要使其成为平行结构,可以有如下的两种改法： … by continued inflation and because of people’s having lost faith in the dollar 【“by + 名词”和“because of + 动名词的复合结构”都是介词短语,属于平行构成】…by continued inflation and by lost of faith in the dollar 【两个平行的by 短语,】 第二种情况中,后一个by 与上文重复,可以省略,变成by continued inflation and lost of faith.答案所说的括号中部分需要改成 "loss of faith" 就是这个道理.======以下答案可供参考======供参考答案1:The price of gold has been influenced by continued inflation and loss of faith in the dollar.这句话的意思是：由于持续的通货膨胀（inflation）和（人们）对美元信心的缺失（loss of faith），黄金的价格受到影响。之所以要换成loss of faith，是因为“and”要连接两个或多个“对等”的成分（词与词，短语与短语，句子与句子）。continued inflation是短语，而because people have lost faith in the dollar却是一个句子。如果您对这个答案满意，请采纳。谢谢！：）供参考答案2:这个应该这么想：influenced by 和 because 其实是一回事儿这句话可以写成：Because of continued inflation and loss of faith in the dollar, the price of gold increased(or has been influenced). 也可以写成：Because people have lost faith in the dollar and the dollar continued inflating, the price of gold has been influenced. 如果我要把上一句的两个the dollar 省略写在一起：continued inflation(of the dollar) and loss of faith in the dollar influenced the price of gold.再反过来写就是一样的了。要知道英语里面because 和influenced by 其实经常可以表述相同的意思，原则是不管用哪个，表意一定要简洁。供参考答案3:因为连词and可连接2个同状态的名词

谢谢了
