She had been worrying ever since the letter arrived. 从句的动作在前,语言逻辑决定了主从句的动作先后顺序,所以从句的过去完成时简化为一般过去时了。所以,当since从句谓语为一般过去时的时候,主句可以是现在完成时,也可以是过去完成时,由句子的语境决定。你的其它理解正确。

严格讲,动词句型应该是七种,而不是五种。因为有的状语是动词语义完整所不可或缺的。例如:The old man died last week. 在这句话中时间状语是可有可无的,不影响动词die的语义完整。因此这个句子虽然有状语,我们仍然说它的动词句型是SV。但在He lives in China.一句中,如果没有时间状语,live(居住)的意义是不完整的...
