902 1 sentence grammar, very confused

The first question: the adverbial, that is, the sentence is meant to indicate the accompanying state of "he stood up *."

The second question: his head is not yet awake There is no mistake in the sentence. I guess you mean that you should add an is after his head, right?

No. If you add is, then his head is not yet awake becomes a complete separate sentence, and if it becomes a separate sentence, then how can it be used as an adverbial in this complete big sentence?

The third question: the weather admitted, not a sentence, is a conditional adverbial, which is used as a conditional adverbial for "we can go out for picnic". There is no conjunction between two sentences because the grammar of the conditional adverbial clause is so prescribed.

If you still want to ask why, go for a grammar book about conditional adverbial clauses. Because it's too cumbersome to explain here......

Fourth question: admitted is a non-predicate verb used to indicate an active relationship with weather. If you don't understand, you can look for a grammar book to read ......Because it's too cumbersome to explain here......

I also give you a suggestion: ask so many questions in the future, give more points, you give 5 points, don't say sorry for the person who helped you, even the brain cells of others you are sorry, it is simply an insult to the person who helped you......

If separated by a comma, it is impossible to be a complete sentence before and after. If the sentence is preceded and followed by a complete sentence, it is separated by a semicolon.

It's not clear, it should be counted as an adverbial.

It can't be a verb, so it's an adjective.

admitted, key: both sides of the comma can't be sentences!

we is the subject and trust is the predicate, followed by the object clause that is omitted as the object. where you will see to is the subject-verb from which it is the formal object from which the object replaces the that clause that follows, that the order is shipped within the stipulated time is the object clause in the object-from, and the true object in the object-from. as any delay would cause us no little financial loss.

is an adverbial clause.

Meaning of this sentence: We believe that you will deliver the goods on time, and the delay will cause us great economic losses.

You're not a grammar problem, you're not good at words, you can't understand the meaning of the whole sentence, so you don't know which word is more appropriate.
