    中考英語被動語態(tài)全解
    被動語態(tài)全解
    語態(tài)是動詞的一種形式,表示句子中主語和謂語動詞的關(guān)系,主動語態(tài)表示主語是動作的執(zhí)行者,被動語態(tài)表示主語是動作的承受者。只有及物動詞才能用于被動語態(tài)。
    本冊書我們將學(xué)習(xí)被動語態(tài)的三種時態(tài):
    (1) 一般現(xiàn)在時的被動語態(tài)
    (2) 一般過去時的被動語態(tài)
    (3) 含情態(tài)動詞的被動語態(tài)
    一般現(xiàn)在時的被動語態(tài)
    一般現(xiàn)在時的被動語態(tài)由"助動詞be 的現(xiàn)在式am / is / are + 及物動詞的過去分詞 + (by)"構(gòu)成。
    基本句式
    肯定式:主語調(diào) + am /is /are +過去分詞+( by)
    Bicycles are sold in that shop .
    Football is played all over the world by people.
    否定式:主語+am/ is /are + not + 過去分詞+(by)
    Bicycles are not sold in that shop .
    Football is not played all over the world by people.
    一般疑問句: Am /Is /Are + 主語+過去分詞+(by)…?
    Is this kind of TV sets made in Guangzhou ?
    Is football played all over the world by people ?
    被動語態(tài)的基本用法:
    (1) 需要強(qiáng)調(diào)動作的承受者時
    The Great Wall is enjoyed by millions of people all over the world
    English is widely spoken in the world now.
    Water is needed badly by the crops here .
    (2) 不知道或沒必要指出動作的執(zhí)行者時
    Mr. Wang is invited to the meeting today .
    The problem is dealt with now .
    (3) 當(dāng)說話人需要強(qiáng)調(diào)客觀時
    It is said that she was a beauty when she was young .
    主動語態(tài)轉(zhuǎn)換不被動語態(tài)的步驟
    1, 把原主動句中的賓語轉(zhuǎn)換為被動語態(tài)的主語
    2, 把動詞改為被動語態(tài)形式即"be+過去分詞"。
    3, 原來主動語態(tài)句子中的主語,如果需要就放在by的后面以它的賓格形式出現(xiàn)(因為by是介詞,后面需跟賓格作介詞的賓語。)以指明做事的人或物,如果沒有必要,可以省略。
    4, 其它成分不變
    5, 被動語態(tài)中"by+賓語"的省略
    被動語態(tài)句式中的"by+賓語"表示及物動詞所表示動作的執(zhí)行者,但是在遇到以下情況時,表示動作執(zhí)行者"by +賓語"常常被省略。
    (1) 動作執(zhí)行者不確定時
    Paper is made from wood .
    Many people are killed in traffic accidents every year .
    (2) 不必表明動作執(zhí)行者時
    English is also spoken as the second language as well as one of the official languages
    Football is played in most schools。
    (3 ) 動作執(zhí)行者為一般大眾時
    Both English and Spanish are spoken in this area.
    一般過去時的被動語態(tài)的基本句式
    (1) 肯定式:主語+ was /were +過去分詞+by
    It was made in Beijing Ren'ai Education Institute .
    These computers were made in the USA ?
    (2) 否定式:主語+was /were + not + 過去分詞+ by

    This question was not discussed at the meeting yesterday .
    (3) 一般疑問句:Was /Were + 主語+過去分詞+by ?

    When was it invented
    教你一招

    如果句子為一般過去時,主動語態(tài)用did ,被動語態(tài)用was /were .
