第一题because。。therefore都是状语从句的内容，第二题用therefore就没有主句了

还是没有太明白，另外一题中A选项的and 和therefore 还都是连词词性么？请大侠们在详细给偶将一下。谢啦！！

明白了，是不是说第一题前面是一个原因状语从句，and therefore 都是从句的一部分，而it is being 为主句。而170题如果这样将and therefore 加到状语从句中句子就没有主句了。therefore is an adv.,刚才弄错了

谢谢二楼

个人感觉169中的Because..是整句话的大因,而Therefore是状语从句中的小因,所以可以在这里共用,并不重复.

顶，同意四楼。therefore是adv，最主要的是170中Because。。。，and。。。两个句子两个连词了

我觉得第二题是因为because 与and都是连词，所以连词多于谓语，句子不成立
