Singular: a pen, an apple, this book, that phone, my bag, it is ...
Plural: pens, apples, these books, those phones, my bags, they are ...

✅ It is a box.
✅ They are boxes.

Singular and Plural Nouns 规则

  • 单数可数名词前通常需要有一个词。这通常是a/an，但也可以是the、this、that、my以及类似的词。我们通常在辅音音素前用a，在元音音素前用an。
    ✅ a pen
    ✅ a river
    ✅ an apple
    ✅ an elephant
    ✅ this book
    ✅ my phone
  • 要把名词变成复数，我们通常加上-s。
    ✅ book → books
    ✅ dog → dogs
    ✅ phone → phones
  • 如果名词以 -ch、-sh、-s、-ss、-x 结尾，我们通常加上 -es。
    ✅ watch → watches
    ✅ dish → dishes
    ✅ bus → buses
    ✅ box → boxes
  • 如果名词以辅音字母 + y结尾，y通常变为ies。如果y前面是元音字母，我们通常只需加上-s。

  • 一些以 -f 或 -fe 结尾的名词，其复数形式变为 -ves。

    ✅ This is a pen.
    ✅ That is a phone.
    ✅ These are pens.
    ✅ Those are phones.
