三年級英語單數(shù)句和復數(shù)句的知識點復習

  口訣:

  單數(shù)句子變,變化規(guī)則要記住。

  名詞代詞要變化,am, is要變are。

  this, that變成啥,these, those來替它。

  he, she, it要變啥,全部變they不用怕。

  I要變we莫落下,名詞后面把s/es加。

  名前冠詞去掉它,其余成分原樣加。

  具體注意下面的六要素:

  1.單數(shù)主格人稱代詞要變成相應的復數(shù)主格人稱代詞,即I→we; you→you; she, he, it→they。 如: She is a girl.→They are girls.

  2. am, is要變?yōu)閍re。 如: I'm a student. →We are students.

  3.不定冠詞a, an要去掉。如: He is a boy. →They are boys.

  4.普通單數(shù)名詞要變?yōu)閺蛿?shù)形式。如: It is a cat. →They are cats.

  5.指示代詞this, that要變?yōu)閠hese, those。如: This is a book.→These are books.

  6. man, woman作定語修飾可數(shù)名詞時,要在 "數(shù)"上與被修飾名詞保持一致。但其他名詞修飾名詞表示 "性質"時,不作變化。

  如:

  He is a man doctor.→They are men doctors. This is an apple tree.→They are apple trees. 單復數(shù)相互轉換,每空一詞(含縮寫)。

  1. The woman is a nurse.(改為復數(shù)句)

  The _________ _________ _________.

  2. There are some old cars.(改為單數(shù)句)

  There _________ _________ old _________.

  3. He has a new book.(改為復數(shù)句)

  _________ _________ new _________.

  4. Are these your chicks ?(改為單數(shù)句)

  _______ _______ your _______?

  5. Is there a sheep in the playground?(改為復數(shù)句)

  ________ there ________ ________ in the playground?
