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.
