        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.

        They aren't in the kitchen.

        They're not in the kitchen.

        時態(tài)中的助動詞be:

        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.

        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:

        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。
