Summary. Because if the word why is used to explain why it leads to the reason adverbial clause, and this sentence is not followed by the reason adverbial clause.

What is the grammatical problem?

the reason is—-i missed the bus. a. that.

b when c why d what this question chooses athat to guide the predicative clause and does not make the component, but the choice c is not okay, I feel that the choice of c also makes sense, this reason is why I missed the bus and c can also be a loss to guide the predicative clause to disturb filial piety, why can't you choose c.

Is it okay to choose C?

C cannot be selected, because if the word "why" is used to indicate that what leads to the adverbial clause of reason, and this sentence is not followed by an adverbial clause of reason.

Why can also lead to predicative clauses.

If you change it to this is the reason, use why

reason as the subject of the table can never be used as why, right?

It is also possible to use why in the predicative clause.

Use this way: this is why can be followed by it.

That's why we missed the bus.

reason is the subject in the main clause, and the conjunction of the predicative clause should use that, and not the reason is the only thing that is the sensitive. Because such a sentence is stating the content of reason, there is no shortage of other meanings.

I don't know if I explained it to you.

The basic grammar knowledge of English is as follows:

Bootstrap Comparative Grade:

1) "as + adjective or adverb primary + as + object being compared" structure. Example sentence: He studies as hard as youHe learns as hard as you do.

2) In a negative or interrogative sentence, you can use not so....as….Example sentence: He can notrun so as fast as youHe can't run as fast as you.

Guided inverted sentence pattern: only + adverbial (or adverbial clause) is at the beginning of the sentence, and the sentence is partially inverted.

Example sentence: Only by diligence and honesty can one succeed inlifeOnly with diligence and integrity can a person succeed in life.

Note: But only when modifying the subject, it is not inverted. Example sentence:

onlythat girl knew how to work out the problem.Only the girl knew how to solve that problem.

Bootstrapping subjunctive mood: The subordinate clause after wish, when indicating a situation contrary to the facts, or a wish that is unlikely to be fulfilled in the future, has the verb form of its object clause is:

Indicates the subjunctiveness of the present situation: the clause verb is expressed in the past tense or the past continuous tense, and the past tense of be is expressed in were

i wish i knew the answer to the question.I would like to know the answer to this question. (Unfortunately I don't know.) )

Indicates the subjunctiveness of the past situation: the clause verb uses had + past participle.

i wish (that) i hadn’t wastedso much time.I regret not wasting so much time. (It's actually wasted.) )

Expresses a subjective desire for the future: The predicate verb form is "would should could might + verb form". In this case, the subject of the main clause cannot be the same as the subject of the clause because of the subject clause.

Whether the expected action of the clause can be achieved depends on the attitude or willingness of the subject of the clause (except for non-action nouns).
