2013中考英語備考:主謂一致問題(必背重點)

字號:


    1、謂語和謂語基本保持單復數(shù)的一致,即:主語是可數(shù)名詞單數(shù)或不可數(shù)名詞時,謂語動詞用單數(shù)形式:如:
    The trousers are very cheap and I want to take them.(褲子很便宜,我想買)
    6、a lot of 后跟名詞復數(shù)時謂語用復數(shù)形式,跟不可數(shù)名詞時謂語用單數(shù)形式。如:
    A lot of students are playing baseball now.(現(xiàn)在有許多學生在打壘球)
    A lot of time was wasted on that work.(大量的時間花在了那個工作上)(被動句)
    7、and 連接兩個名詞做主語時,謂語原則上用復數(shù),但是兩個名詞若構(gòu)成一個整體事物時,謂語則用單數(shù)。如:
    The teacher and his son are picking apples now.(老師和他的兒子在摘蘋果)
    Fish and chips is very famous food. (魚和薯條是一種出名的食品)
    8、 there be 句型中be的單復數(shù)一般由靠近的名詞決定。如:
    There is a table and four chairs in the room.(房間里有一張桌子和四張椅子)
    9、用both…and…連接兩個事物做主語時,謂語一般用復數(shù)。如:
    Both you and I are required to be here tomorrow.(你和我明天要求都來)
    10、主語中含有with的短語時,謂語單復數(shù)由with之前的人物決定。如:
    A woman with a 7-year-old child was standing at the side of the road. (一名婦女帶著一個七歲的孩子(當時)就站在路邊)
    11、either…or…或者 neither…nor…連接兩個人物做句子主語時,謂語采用就近原則。如:
    Either you or he is right.(要么是你對,要么是他對。/你和他有一個人是對的)
    Neither you nor I am going there.(你和我都不打算去那里)
    12、表示一段時間或長度概念的復數(shù)名詞做主語時,謂語一般用單數(shù)。如:
    Two months is not a short time.(兩個月不是個短時間)
    Two thousand kilometers is quite a long distance(距離)。(兩千千米是相當長的一段距離)
    13、主語中含有half of… / three quarters of… / all (of) the …等詞語時,謂語的單復數(shù)由名詞確定,如:
    Over three quarters of the information on the Internet is in English.(因特網(wǎng)上四分之三以上的信息是用英語寫的)
    A third of the students were playing near the lake.(學生的三分之一(當時)正在湖邊玩耍)
    All of the water in these rivers has been polluted.(這些河流中的水已經(jīng)被污染了)(被動句)
    但是,population一詞又有特殊情況:
    What's the population of China?(中國人口是多少?)(句子用單數(shù))
    Three quarters of the population in this city are Arabs(阿拉伯人)。(這個城市四分之三的人口是阿拉伯人)(句子用復數(shù))
    ?
