Works meant that there was no S in the work. And how to determine its singular and plurals and predicates?

It was a complicated process to determine the authenticity of a piece of work. Many factors needed to be considered. Here are some ways that might help determine the authenticity of a work: 1. Confirm the prototype or foundation of the work: If the plot, characters, locations, or elements in the work are constructed on the basis of other works or archetypes, then the work may be original. For example, if the characters in the work were adapted from other works or the background of the work was borrowed from other works, then the work might be original. 2. Confirm the original creation of the work: If the plot, characters, locations, or elements in the work are independently created by the author, then the work may be original. For example, if the character's personality, behavior, appearance, etc. in the work were independently created by the author, then the work might be original. 3. Confirm the creativity of the work: If the plot, characters, locations, or elements in the work are unique and innovative, then the work may be original. For example, if the novel's creativity lies in plot design, character creation, or story structure, then the novel may be original. 4. Confirm the cultural background of the work: If the plot, characters, locations, or elements in the work reflect a specific cultural background, then the work may be original. For example, if the character behavior, plot design, or dialogue in a work reflects the values and way of thinking of a particular culture, then the work may be original. 5. Confirm the intellectual property rights of the work: If the work has been registered or obtained intellectual property rights by others, then the work may not be original. In this case, the copyright or intellectual property of the work belongs to others and cannot be freely created or adapted. There were many factors that needed to be considered to determine the original quality of a work. It is recommended to seek the help of professionals or refer to relevant legal documents when determining the authenticity of the work.

One way to tell is by the author's intent. If they aim to present real information or experiences, it's nonfiction. If they're creating an imaginative world or story, it's fiction. Also, the style of writing can give clues. Nonfiction often uses more factual language and references, while fiction may have more creative and descriptive language.

Mix up your characters. Have characters from different cultures, backgrounds, and time periods interact in a way that is not typical. And don't be afraid to play with language. Use new words, or use old words in new and creative ways. For example, create new idioms or play with the rhythm of sentences. All these can contribute to creating a work that is meant to be novel.

It often depends on factors like the significance of the event, public interest, and the potential impact on society.

Fiction is uncountable and is considered singular. For example, 'This fiction is very interesting.'

The plural of 'life story' is 'life stories'.

The English rule for plurals is that when a verb ends with "-s", it is not prefixed with "-s" in the plurals. For example, apples → apples. Noun ending in "-es" is prefixed with "-es" in the plurals, for example:pears(pear)→pears(pear fruit). Noun ending in "-ness" is prefixed with "-ness" in the plurals, for example: city → cities. It should be noted that some terms end with "-s" or "-es" in the plurals, and they need to be prefixed with "-s" or "-es" for example: dog → dogs. In addition, some terms can also end in other forms, such as-ness(possessive)-s(singular)-es(plurals). These forms need to be judged according to the context.

Can you add s to the English plurals of novels? Under normal circumstances, the English plurals in novels did not add an 's'. This is because novels are usually published in the singular form. For example, a novel might be called The Catcher in the Rye, and its singular form would also be The Catcher in the Rye rather than The Catcher with the Rye. However, there were also some special circumstances that could occur. For example, if a novel has more than one author or is published by more than one publishing house, it may appear in the plurals. In this case, the author or the publishing house may give their work a different name, such as The Catcher in the Rye by J.D. Salinger or The Catcher with the Rye by J.D. Salinger. In this case, the form of the multiple number might need to be determined according to the specific situation.

The English plurals of novels could not be added with s because novels usually existed in singular form, including novels, collections of novels, single volumes of novels, etc. In English, the plurals usually refer to multiple novels with the same theme or style rather than the plurals of multiple novels. If there was a need to express multiple novels, they would usually use the plurals of "novels" or "novellas".

It's 'life stories'.
