英语复数单数总结

English nouns often add "s" to form the plural.

• "is" becomes "are" after singular nouns like "she" or "book".
• Exceptions like "man" to "men" or "child" to "children" are common.
• Watch out for irregular plurals like "mouse" to "mice" or "goose" to "geese".
• Use "was" with plural nouns in past tense, not "were".
• Practice with common irregular nouns to avoid mistakes.
