be動詞后不一定加動詞ing,也可以加動詞ed(過去分詞)。be+動詞ing表示進行時態(tài),be+動詞ed表示被動。

擴展資料

  “Be+現(xiàn)在分詞”以組成進行式時態(tài)(Continuous Tenses),如:

  Tony's maid is washing his new car.

  The children are playing in the field.

  Samuel was eating when I came in.

  We have been living here since 1959.

  形式:

  有不同的be動詞,基本上為:

  am,is,are,was,were,been,being,be。

  被動語態(tài):

  被動語態(tài)的基本結(jié)構(gòu)為be+done(Be動詞+動詞過去分詞)

  一般現(xiàn)在時:am/is/are+done

  一般過去時:was/were+done

  一般將來時:will+be+done

  現(xiàn)在進行時:am/is/are+being+done

  過去進行時:was/were+being+done

  現(xiàn)在完成時:have/has+been+done

  過去完成時:had+been+done

  一般構(gòu)句:

  代詞/專有名詞+be+普通名詞(如我們是親兄弟)

  代詞+be+專有名詞(如我是愛麗絲)

  代詞/專有名詞+be+物主代詞+普通名詞(如我是你的親姐妹)

  當(dāng)“be”要在祈使句中出現(xiàn)時,陳述句可借助助動詞“do”,否定句必須在前加上助動詞“don't”,如:

  Don't be silly!

  Do be obedient!

  Be careful!

  Don'tbe a fool!
