求哪位英语语法大神能帮我分清下面每句话的不同成分，比如主语是哪个，表语是哪个……

1. When you still have a reasonable amount of control over your circumstances状语从句作状语,

you是主语 should do 是谓语what really matters是宾语从句作宾语.
2.During early adulthood是介词短语作状语 your worldview是主语 is still being formed是谓语.
3.It是形式主语 is是系动词 important是表语

 to steward this time –to give yourself opportunities to grow是真主语.
4.Soon是状语 came是谓语 the order是主语 to start the general attack是不定式短语作定语修饰 the order.

1. When引导的时间状语从句，you是主语，should助动词，do谓语，what really matters宾语从句。

2. During early adulthood 时间状语，your worldview主语，is系动词，being formed表语。

3. it主语，is系动词，important to ... 表语。

4. Soon时间状语，came谓语，order 主语。

   主语好区分，应该不成问题。能做表语的只有be在不同情况下的不同形态、look、appear、seem等等。
