文法問題 grammar

She is not coming home tonight.

is---verb
come---verb

一句sentence不可有2v同時存在.所以將come轉做gerund動名詞

Gerund=V+ing

gerund(動名詞)都是Noun的一種

e.g.pronoun都是Noun的一種

Pronoun
e.g. He.She.It.I.You.We.They

" She is not coming home tonight." 是不應該有"tonight(adv)"才合理.

" She is still working, not coming home yet." 我覺得 "yet(adv)較妥當.

She is not come home tonight.......OK.

She is not coming home tonight = She will not come home tonight.

Whenever there is verb to be ( am , are, is , was , were ), all verbs need to add ING.

"coming" is used instead of "come" because the "present continuous tense" (is coming) is used in this sentence to replace the "simple future tense" (will come), to describe an action in the future.

Therefore, "She is not coming home tonight." = "She will not come home tonight".

The usage of "present continuous tense" instead of "simple future tense" for a future action is becoming more popular, especially in informal or conversational English.

However, "She does not come home tonight." does not describe a future action, so "come" is not used.

If we want to describe a fact or usual event, we will use "come". For example: "She does not come home on Monday nights".
"She does not come home any more."

She is not coming home tonight.
coming is a participle.
participle n,(grammar) in English is a word formed from a verb, ending in ---ing(= the present participle of come.)
Hence:-Present Infinitive--come
Past Tense---came
Past Pasticiple---come.
Irregular verb=verbs conjugated irregularly.
One cannot find here when
--ed, --en, etc. (=the past participle)
where participial is the adjective.
