Individual entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing from commercial resources. 杨鹏解释说这个是双重否定+倒装，正常语序是: ....do not necessarily because ....rely on their kin. 我觉得他的解释没问题，但是怎样才可以看出这个句子是否定在because上，而不是否定在rely上呢？我觉得在考场上看到这句句子，第一反应就是理解为否定在rely上，毕竟非常靠近rely，而不是because. 难道又是从句意上推测验证吗？ 另外一种办法，就是把这句句子看成：Individual entrepreneurs do not necessarily (rely on their kin because they cannot obtain financial backing from commercial resources). 看成对后面整个短语的一个否定，好像语意上也正确。但是还是很困惑与怎样第一反应就直接知道是do not because, 而不是do not rely? |
