考研英语09text2英文句子结构分析
DNA testing is also the latest rage among passionate genealogists--and supports businesses that offer to search for a family's geographic roots.
从-AND后开始分析.businesses that .这里面的that是什么用法?如果是DNA testing is also the latest rage among that offer to search for a family's geographic roots.那么offer为什么不加s?
答
is 和 supports 并列,that引导的是定语从句,解释businesses那请问offer to do在这里是什么意思呢？offer后面的都是解释businesses的。基因检测也是最近引起*的系谱专家兴奋的一个方面，它为家族的地理寻根提供了更多有力的依据。businesses在这里不能直译。Businesses offer genealogists to search ...楼主现在明白offer to do 是什么意思了 吗》
