考研英語(yǔ)語(yǔ)法講解之名詞從句五大問(wèn)題

字號(hào):

一、名詞從句的本質(zhì)。
    1. 概念:就是把一個(gè)完整的句子當(dāng)一個(gè)名詞來(lái)使用。那么從句就具備了名詞所具備的所有性質(zhì)。主語(yǔ)、賓語(yǔ)、表語(yǔ)、同位語(yǔ)。
    2. 引導(dǎo)名詞從句常用的連詞。有三類(lèi):1)that; 2)whether,if; 3)when,where ,how等連接副詞或what,who,whose等連接代詞。
    That引導(dǎo)的名詞性從句不能做任何句子成分。what一定在從句中充當(dāng)主語(yǔ)或者賓語(yǔ)。Which 和whose 后面必須接名詞。例如:
    Concerns were raised __witness might be encouraged to exaggerate their stories in court to ensure guilty verdicts。
    A.what B.when C.which D.that
    3)多重的名詞從句現(xiàn)象。例如:
    I realized that what I said was not exactly what meant to say。
    考題:Prof. Lee’s book will show you ________ can be used in other contexts。
    [A] that you have observed
    [B] that how you have observed
    [C] how that you have observed
    [D] how what you have observed
    二、名詞從句中的主語(yǔ)從句
    主語(yǔ)從句有如下幾種表示方式:
    1。用which, that放在句首引導(dǎo)主語(yǔ)從句。例如:
    That the seas are being overfished has been known for years。
    3。用it is +ved+that…例如:
    It is believed that you are good boy。
    3. 用whether引導(dǎo)主語(yǔ)從句。例如:
    Whether the eyes are the windows of the soul is debatable。
    三、賓語(yǔ)從句
    需要掌握的幾點(diǎn):
    及物動(dòng)詞后面的賓語(yǔ)從句。2005年例句:
    Do you remember all those years when scientists argued that smoking would kill us?
    四、表語(yǔ)從句
    就是一句話(huà)做另一個(gè)句子的表語(yǔ)。就是把從句放在系動(dòng)詞的后面。1997年例句:
    A report consistently brought back by visits to the US is how friendly, cautious and hopeful most Americans were to them。
    五、同位語(yǔ)從句
    就是用來(lái)補(bǔ)充說(shuō)明同位語(yǔ)的名詞成分的句子。結(jié)構(gòu)是:名詞+that+從句。
    同位語(yǔ)從句與賓語(yǔ)從句和定語(yǔ)從句的區(qū)別:引導(dǎo)賓語(yǔ)從句和定語(yǔ)從句的的that, which可以省略,而引導(dǎo)同位語(yǔ)從句的that不能省略。定語(yǔ)從句中的that必須在從句中扮演主語(yǔ)或者賓語(yǔ)。同位語(yǔ)從句的that不扮演任何成分。例如:
    There is a popular saying that family instability causes social instability. that不做句子成分。
