托??荚囕o導(dǎo):語(yǔ)法講解(46)

字號(hào):

第二節(jié) 狀語(yǔ)
    句子中除了主謂結(jié)構(gòu)外,還可能包含表示時(shí)間、地點(diǎn)、方式等內(nèi)容的狀語(yǔ),通常由副詞、介賓短語(yǔ)來(lái)承當(dāng)。
    如:At night, I don’t go out very often., 此句中at night, very often都是狀語(yǔ)
    介賓短語(yǔ)作狀語(yǔ)是填空題的重要考點(diǎn),若空格處或空格所在部分之后是完整的主謂句,且兩部分之間多以逗號(hào)隔開(kāi),若選項(xiàng)中無(wú)從句結(jié)構(gòu)或分詞,此時(shí)空格處需填入介賓短語(yǔ)作狀語(yǔ)。
    例題:
    (1)
    ----irritating effect on humans, the use of phenol as a general antiseptic has been largely discontinued.
    (A) Its
    (B) Where its
    (C) Since its
    (D) Because of its
    答案:D
    解釋:此句主干完整, 主語(yǔ)是the use of phenol as a general antiseptic, 謂語(yǔ)是has been largely discontinued, 逗號(hào)之前應(yīng)是狀語(yǔ). A構(gòu)成名詞短語(yǔ), 與該句主語(yǔ)發(fā)生沖突; B、C欲構(gòu)成從句, 但缺少?gòu)木涞闹^語(yǔ)動(dòng)詞; D恰好構(gòu)成表示原因的狀語(yǔ), 短語(yǔ)because of 之后常接名詞或動(dòng)名詞表原因, 如: He failed the exam because of his carelessness.
    (2)
    ----a child, sculptor Anne Whitney showed an eager intellect and artistic talent that her parents recognized and encouraged.
    (A) Has been
    (B) It was while
    (C) She was
    (D) As
    答案:D
    解釋:此句主干完整, 主語(yǔ)是sculptor, 謂語(yǔ)動(dòng)詞是showed, 之后是帶有定語(yǔ)從句的賓語(yǔ), 需填入狀語(yǔ). A、B、C 中的has been、was與showed相沖突, 違背謂語(yǔ)原則. 介詞詞組As a child 相當(dāng)于When she was a child.
    (3)
    .----, snakes frequently subdue their prey without injecting poison.
    (A) Contrary to general belief
    (B) General belief contrary to
    (C) Belief contrary to general
    (D) Contrary belief general to
    答案:A
    解釋:給出部分是完整的句子, 從選項(xiàng)中可見(jiàn)此處缺少狀語(yǔ), be contrary to是固定詞組, 表示“與……相反”, 介詞to后需接賓語(yǔ), 只有A符合上述條件
