本剧中COVERED WITH 出现两次,为什莫第一次出现前没有BE动词,第二次却有?

the contry,covered with cherry tree flowers,looks as though it is covered with pink snow本剧中COVERED WITH 出现两次,为什莫第一次出现前没有BE动词,第二次却有?
本句中的句子成分的主语是“the contry”,谓语是“looks”,而第一个,covered with 是非谓语,它与本句的主语是被动关系,所以用covered with (非谓语的形式就是 动词后加ING ,动词后加ED,也就是过去分词.前面不可能有be出现,这是不符合固定搭配的.)
而第2个是though引导的从句,covered with 是从句的谓语.由于是被动关系,所以用is covered with pink snow

第一个 covered 是从句,第二个is covered是叫什么来着?语法我很差的。

第一次出现时,其实是省略了which is,直接用过去分词作状语
第二次出现时,是as though的从句,当然得要用上be动词,否则从句就没有谓语了啊
