og上的语法疑问

星月多多

（1）The peaks of a mountain range,acting like rocks in a streamed,produce ripples in the air flowing over them;the resulting flow pattern,with (stationary creats and troughs although they are formed by rapidly moving air,is) know as "standing waves".
Choice E uses the correct verb form,(is) ,but it incorrectly introduces a dependent adverbial (although) clause into a predicates of full clauses.
Such dependent clauses can only occur in the predicates of full clauses.
能帮忙解释一下这个语言点，是什么意思呢？

（2）Despite protects from some waste-disposal companies,state health officials have ordered (that the levels of bacteria in seawater at popular beaches be measured and the results) published.
这里是不是少了一个be，难道不是应该the results be published？

谢谢：）[em15]

这种非独立短语只能存在于有明确谓语动词的句子中。

Such dependent clauses can only occur in the predicates of full clauses是指？

第二题补充一下：
（lzm）在and,but和or的并列句中，后面分句中与前面分句相同的部分通常被省去。

(1)我给你搞糊涂了，原来OG上是这样说的：Choice E uses the correct verb form,(is) ,but it incorrectly introduces a dependent adverbial (although) clause into a  prepositinal phrase (with crests....) 而不是你说的into a predicates of full clauses
意思是说在with介词短语后面不能引导一个独立的ALTHOUGH状语从句。
（2）平行结构中后面助动词可以省略
