When the phrase caused by only is used as an adverbial in the clause, the subject verb should be inv

This is simple, only when the only+ adverbial is placed at the beginning of the sentence in the form of a partial inverted sentence, this adverbial can be a word such as here there, then, now, a prepositional phrase or a sentence, an adverbial sentence guided by a subordinate conjunction such as when where how if before. Such as:

i realized that i was wrong only then.Only then did I realize I was wrong.

only then (a word, at that time, the adverb of time as an adverb) did realized that i was wrong

you can find him only in the library.You can only find him in the library.

only in the library can you find him

they will stay at home only when it is hot.They only stay home when it's hot.

only when it is hot(whenячфъфъфъШыШыШ

There are also some inverted sentences that are very simple to change, which is basically similar to changing general question sentences.

At the same time, remember only after + adverbial to invert, so:

Only you would ask this question. only you can answer this question.This sentence is not an inverted sentence because you after only is not an adverbial.

only at the beginning of the sentence to indicate the adverbial；The sentence needs to be inverted, and it is not completely inverted (i.e. the modal verb is used.

Auxiliary verbs, be verbs.

and so on, the position of the substantive verb remains the same).

For example: only in this way, can we realize our dreamOnly in this way will we be able to achieve our dreams.

only when we try our best, will we succeed.We will only succeed if we do our best. (Note the clause that follows only.)

There is no need to invert, the main clause is inverted).

Usage. Only is used as an adjective to mean "unique, only", which can modify both singular and plural nouns. It is often preceded by the definite article the or the adjective possessive pronoun.

When only with another adjective or number.

When used in conjunction only, only should be placed in front of them.

Except for being used to mean "only child", only is generally not used in the indefinite article.

After an.

In the two most common all-inverted sentences, their predicate verbs happen to be either intransitive verbs or be verbs, so there is no object, and there is no such thing as worrying about what you say. And their subjects must not be pronouns. As for the remaining components in the sentence, generally speaking, the adverbial or predicate will mention the beginning of the sentence.

Other components depend on the meaning of the sentence or the characteristics of the sentence structure.

The first is a completely inverted sentence form "predicate the subject". For example, the original sentence is: the bus you are waiting for comes here, inverted as:

here comes the bus you are waiting for.

The second is a completely inverted sentence "table bes the master". For example, the original sentence is: Our English teacher is in the classroom, and it is inverted as:

in the classroom is our english teacher.

The example you gave is a subject-verb structure with no object.

And the example happens to be a special case, or a customary expression in English. If you really put the predicate verb at the beginning of the whole sentence in all inversions, it will be bare and abrupt, so you usually add dotted words in front of it, such as here, there, prepositional phrases, etc.

First of all, let me correct your mistakes. There is not an object, just an adverb, do adverbial. One type of structure that is completely upside down is:

adv.+ verb.+ Subject.

There is not an object, it is an adverbial of place.

There is not an object, this sentence is all upside down.

Actually, this sentence is an inverted sentence.

If the predicate takes the object, in the complete inversion, the object and the predicate verb advance to the beginning of the sentence together. For example: distinguished guests and friends, welcome to our school

attending the ceremoney of 50th anniversary this morning are our alumn from home and abroad.

1. The only+ adverb is at the beginning of the sentence.

Example sentence: only by shouting was he able to make himself heard

He had to shout to make others hear him.

2. The only+ prepositional phrase is located at the beginning of the sentence.

Example sentence: only by working hard can you succeed

You can only succeed if you work hard.

3. The only+ adverbial clause is located at the beginning of the sentence.

Example sentence: It was only after her death that I realized her value.
