句子分析，认识句子成分

原句1：I always try to take notes when I'm reading and so sometimes I find that I'm almost copying out the whole article because I can't decide what the really important points are.

（因为连接词and连接了两套主谓结构，所以说并列复合句。

而在and连接的两个句子中又包含了两个从句。

when I'm reading是I always try to take notes的时间状语从句。

that I'm almost copying out the whole article是so sometimes I find的宾语从句。

what the really important points are是I can't decide的主语从句，解释说明了主句。

而because I can't decide what the really important points are是so sometimes I find that I'm almost copying out the whole article原因状语从句，解释说明了主句。）

原句2 ：has clearly been moved since the storm ended.

（he pointed out是The cover of the manhole的定语从句，修饰the manhole。

The cover of the manhole he pointed out是主语从句

since the storm ended是The cover of the manhole he pointed out has clearly been moved状语从句。

所以说复杂句。
