2019-2020年高考英語二輪復(fù)習 分析一致性 巧妙學數(shù)詞教案 數(shù)詞屬限定詞，它與很多詞存在一致關(guān)系，分析這些一致關(guān)系，可以巧妙地學習數(shù)詞。 一、 分析數(shù)詞與名詞一致性，巧妙學習數(shù)詞 基數(shù)詞（大于1）后面應(yīng)接復(fù)數(shù)名詞，但復(fù)合形容詞中的基數(shù)詞應(yīng)修飾單數(shù)名詞，序數(shù)詞后面應(yīng)接單數(shù)名詞。表示第幾時可用the+序數(shù)詞+單數(shù)名詞，也可用單數(shù)名詞加基數(shù)詞。 例1：She has one pink pen and two grey ________. A. one B. once C. ones D. ones 析：D為正確答案。two后面應(yīng)接復(fù)數(shù)名詞。 例2：We are going to learn ________ next week. A. Lesson Twelve B. Lesson Twelfth C. Twelfth Lesson D. the Lesson Twelfth 析：A為正確答案。第十二課可表達為Lesson Twelve或the twelfth lesson。 例3：Its ________ walk from here to my school. A. two-hours B. two hours C. two-hour D. a two-hour 析：D為正確答案。該空為復(fù)合形容詞作定語，中間的名詞應(yīng)用單數(shù)。 二、 分析數(shù)詞與量詞一致性，巧妙學習數(shù)詞 數(shù)詞后面接量詞時，數(shù)詞無論有多大，量詞都要用單數(shù)形式。 例1：Two ________ died of cold last winter. A. hundreds old people B. hundred old people C. hundreds of old people D. hundred old peoples 析：B為正確答案。使用數(shù)詞+量詞+復(fù)數(shù)名詞結(jié)構(gòu)時，量詞應(yīng)用單數(shù)形式。 例2： Shortly after the accident, two________ police were sent to the spot to keep order. A. dozen of B. dozens C. dozen D. dozens of 析：C為正確答案。two后面應(yīng)接單數(shù)量詞。 三、 分析數(shù)詞與介詞一致性，巧妙學習數(shù)詞 數(shù)詞前面加介詞常表示年齡或年代，此時數(shù)詞需用復(fù)數(shù)形式。這樣的場合常見的有：in the 1990s / 1990s (在二十世紀九十年代), by twos and threes (三三兩兩地), in the eighties (在八十年代), in ones sixties (在某人六十多歲時)。 例1：The hero of the story is an artist in his________. A. thirtieth B. thirty C. thirtys D. thirties 析：D為正確答案。in his thirties意為"在他三十多歲時"。 例2：It is rare in ________ that people in ________fifties are going to university for further education. A. 90s； the B. the 90s； / C. 90s； their D. the 90s； their 析：D為正確答案。in the 90s表示在90年代；in their fifties表示在他們五十多歲時。 四、 分析數(shù)詞與動詞一致性，巧妙學習數(shù)詞 分數(shù)、百分數(shù)作主語時謂語動詞取決于of后面的名詞；one of+復(fù)數(shù)名詞表示總數(shù)超過一個，作主語時動詞用復(fù)數(shù)，the only one of+復(fù)數(shù)名詞表示總數(shù)中只有一個，作主語時動詞用單數(shù)；表示重量、長度、價值、時間等概念的復(fù)數(shù)名詞可看成一個整體，作主語時動詞用單數(shù)。 例1：Ten years ________ a very short time in history. A. is B. are C. has been D. were 析：A為正確答案。Ten years 可看成一個整體，作主語動詞用單數(shù)。 例2：As we all know, three feet________ equal to one meter. A. are B. is C. were D. was 析：B為正確答案。three feet可看成一個整體，作主語動詞應(yīng)用單數(shù)。 例3：He is the only one of the employees who________ sent abroad for further training for five years. A. is B. are C. have been D. has been 析：D為正確答案。析語境可知，該句表示他是五年來被派往國外培訓的唯一一位雇員，所以謂語動詞應(yīng)用現(xiàn)在完成時單數(shù)形式 has been。 例4：________ of the land in that district ________covered with trees and grass. A. Two fifth; is B. Two fifth; are C. Two fifths; is D. Two fifths; are 析：C為正確答案。分數(shù)的表示方法為：先講分子，再講分母，分子用基數(shù)詞，分母用序數(shù)詞，當分子大于1時，分母用序數(shù)詞復(fù)數(shù)形式。因為land為不可數(shù)名詞，動詞應(yīng)用單數(shù)形式。 五、分析數(shù)詞與冠詞一致關(guān)系，巧妙學習數(shù)詞 復(fù)合形容詞中基數(shù)詞常與不定冠詞搭配，此時基數(shù)詞若為元音發(fā)音開頭時，應(yīng)在其前面加an，若為輔音發(fā)音開頭的應(yīng)在其前面加a。 例1：Dont take ________ one-sided view of anything. A. a B. an C. the D. / 析：A為正確答案。one為輔音發(fā)音開頭，前面應(yīng)加a。 序數(shù)詞前面通常加the修飾，表示第幾次用the+序數(shù)詞+time，但表示又一次、再一次時，應(yīng)用a+序數(shù)詞+time。 例2： Ive already asked him three times, I wonder if I can ask him________time. A. four B. fourth C. a four D. a fourth 析：D為正確答案。該空語境表示又一次、再一次，應(yīng)填a fourth。 六、分析數(shù)詞與倍數(shù)搭配關(guān)系，巧妙學習數(shù)詞 數(shù)詞與倍數(shù)(times)搭配常用于A is...times as large/long as B句型 (A是B大小/長度的......倍)或A is...times larger/longer than B (A比B大/長......倍)。 例1：The house rent is expensive. Ive got about half the space I have at home and Im paying ________here. A. as three times much B. as much three times C. much as three times D. three times as much 析：D為正確答案。該空表示我所花的費用是家里的三倍，應(yīng)使用A is...times as large/long as B句型，here前面省去了as I pay at home。 例2：Americans eat ________ vegetables per person today as they did in 1910. A. more than twice B. as twice as many C. twice as many as D. more than twice as many 析：D為正確答案。as they did in 1990提示該空格處表示倍數(shù)，可使用A is...times as large / long as B句型。 例3：After the new machinery was set up, the pany produced ________ refrigerators in xx as the year before. A. as twice many B. as many twice C. twice as many D. twice many as 析：C為正確答案。as the year before暗示該空表示倍數(shù)，應(yīng)使用A is...times as large/long as B句型。
