  c) 不以s 結(jié)尾的復(fù)數(shù)后加 ’s children’s shoes

  ? 并列名詞中,如果把 ’s加在最后一個名詞后,表示共有, 如:

  五 數(shù)詞:基數(shù)詞,序數(shù)詞一、基數(shù)詞

  (1)1-20

  twenty-first,two hundred and forty-fifth

  基數(shù)詞轉(zhuǎn)為序數(shù)詞的口訣:

  基變序,有規(guī)律,詞尾加上-th.

  一,二,三,特殊記,詞尾字母t,d,d.

  八去t,九去e, ve要用f替。

  詞的那個名詞決定。

  3、there be 句型的否定句在be 動詞后加not , 一般疑問句把be 動詞調(diào)到句首。
