時間: 家志1175 分享

  學習啦:Be動詞雜英語里有著十分重要的地位,需要牢牢掌握,下面我們一起看看這篇《動詞be解析》。

  Be動詞一般現(xiàn)在時(一般現(xiàn)在時表示通常性、規(guī)律性、習慣性、真理性的狀態(tài)或者動作發(fā)生有時間規(guī)律的一種狀態(tài))有三種形式,記住哦,只有三種形式。它們分別是:am,is,are.

  陳述句:

  The man is a science teacher.

  這個男子是一位科學教師。

  Mary's new dresses are colourful.

  瑪麗的新衣服色彩鮮艷。

  I have been there before.

  我以前去過那里。

  My mother is in the kitchen now.

  我媽媽現(xiàn)在在廚房里。

  疑問句:

  Is the man a science teacher?

  Are Mary's new dresses colourful?

  Have I been there before?

  Is mother in the kitchen now?

  否定句:

  The man is not a science teacher.

  The man isn't a science teacher.

  They are not in the kitchen.

  時態(tài)中的助動詞be:

  We have been living here since 1959.

  被動語態(tài)中的助動詞be

  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

  祈使句中的系動詞be

  Don't be silly!

  Do be obedient!

  Be careful!

  Don't be a fool!

  簡單總結(jié):

  動詞be分為系動詞be和助動詞be兩種,系動詞be是謂語的重要組成部分,助動詞be則只起到形式的作用,由于主語和時態(tài)的要求,動詞be要變成相應的形式。
