        學(xué)習(xí)啦:Be動(dòng)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(dòng)詞be解析》。

        Be動(dòng)詞一般現(xiàn)在時(shí)(一般現(xiàn)在時(shí)表示通常性、規(guī)律性、習(xí)慣性、真理性的狀態(tài)或者動(dòng)作發(fā)生有時(shí)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(gè)男子是一位科學(xué)教師。

        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 isn't a science teacher.

        They are not in the kitchen.

        They aren't in the kitchen.

        時(shí)態(tài)中的助動(dòng)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(dòng)語態(tài)中的助動(dòng)詞be

        一般現(xiàn)在時(shí):am/is/are+done

        一般過去時(shí):was/were+done

        一般將來時(shí):will+be+done

        現(xiàn)在進(jìn)行時(shí):am/is/are+being+done

        過去進(jìn)行時(shí):was/were+being+done

        現(xiàn)在完成時(shí):have/has+been+done

        過去完成時(shí):had+been+done

        祈使句中的系動(dòng)詞be

        Don't be silly!

        Do be obedient!

        Be careful!

        Don't be a fool!

        簡單總結(jié):

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