一、考查數(shù)詞表示編號

    在通常情況下，表示年級、班、行、房間、課的編號要用基數(shù)詞，且位于詞首的字母要大寫，基數(shù)詞居后(若用英語表示，其首字母也要大寫)；若要用序數(shù)詞表示，則序數(shù)詞必須加上the。如：

    Lesson One/ The first lesson (第1課)，Room 306 (306號房間)，Row Four/ The fourth row

(第4排)，Class Three Grade Nine (九年級三班)

    二、考查基數(shù)詞的在拼寫

    對基數(shù)詞的拼寫須注意：⑴1—20應(yīng)當(dāng)逐個記憶，21—99應(yīng)是說整十加上連字符“-”然后再說幾。如：78→seventy-eight ⑵ 百位與十位或個位之間應(yīng)加and。如：675→six hundred and seventy-five。⑶若是四位和四位以上的數(shù)，則是從后面向前數(shù)，每三位為一組，用逗號分開，第一個逗號前是“千”(thousand)，第二個逗號前則是“百萬”(million)，第三個逗號前則是“ 十億”(billion)。如：7,258,369,000→seven billion，two hundred and fifty-eight million，three hundred and sixty-nine thousand。

    三、考查基數(shù)詞hundred/thousand/million/billion的單復(fù)數(shù)形式

    當(dāng)hundred/thousand/million/billion與two/three等數(shù)字連用表示確定數(shù)目時，這類數(shù)詞需用單數(shù)形式；當(dāng)此類基數(shù)詞用來表達(dá)不確定數(shù)目時，即數(shù)百、數(shù)千等意思時，要用“hundreds／thousands／millions／billions + of +復(fù)數(shù)名詞”表達(dá)，其中of不可少，此時hundred之類基數(shù)詞前面不可用具體數(shù)字修飾，但可加many/several。試比較：

      five hundred students             (√)

      five hundreds students            (×)

      ten thousands of students          (×)

many/several thousands of students  (√)

四、考查-ty結(jié)尾的基數(shù)詞的復(fù)數(shù)意義

從20至90以-ty結(jié)尾的基數(shù)詞當(dāng)用來表示年代或歲數(shù)時，此時要出復(fù)數(shù)形式出現(xiàn)。如： in the1990s/in the1990’s在二十世紀(jì)九十年代  in his/her forties在他/她四十多歲時

注意：在“基數(shù)詞-單數(shù)名詞-形容詞”所構(gòu)成的復(fù)合形容詞中，其中名詞要用單數(shù)形式。如：

一個十二歲的男孩→a twelve-year-old boy

一座800米長的橋→an 800-metre-long bridge

女子400米接力→girls’ 400-metre relay race

    五、考查序數(shù)詞的構(gòu)成與功能

    序數(shù)詞除用來表示編號外，還可用來表示事物的先后順序，此時序數(shù)詞多與定冠詞the、物主代詞或名詞所有格等連用。對序數(shù)詞的考查常見于序數(shù)詞的拼寫以及與基數(shù)詞的詞形轉(zhuǎn)換中。應(yīng)關(guān)注下列數(shù)詞的拼寫與轉(zhuǎn)換：

one→first, two→second, three→third；eight→eighth；nine→ninth；five→fifth, twelve→twelfth；twenty→twentieth, forty→fortieth；twenty-one→twenty-first, fifty-nine→fifty-ninth

    六、考查不定冠詞a/an與序數(shù)詞連用

序數(shù)詞除了與定冠詞the、物主代詞或名詞所有格等連用以表示順序外，不定冠詞a／an也能與序數(shù)詞連用，可表達(dá)一種特殊功能，意為“再一”、“又一”，相當(dāng)于another。如：

Then they had a second child—a son.后來他們又有了一個孩子---- 一個兒子。

    七、考查分?jǐn)?shù)詞的構(gòu)成以及當(dāng)其作主語時謂語動詞的單復(fù)數(shù)

1. 分?jǐn)?shù)詞的一般構(gòu)成：分子用基數(shù)詞，分母用序數(shù)詞；除分子是“1”的情況外，序數(shù)詞都用復(fù)數(shù)。如： 1／3 →a(one) third，2／3 →two-thirds， 2／5→two-fifths。

注意：1／2 →one half或a half（但不說one second），1／4 → a(one) fourth/quarter，3／4 → three-quarters/fourths

    2. 分?jǐn)?shù)詞作主語時，謂語動詞的單復(fù)數(shù)應(yīng)由of后面名詞的數(shù)確定：of后面的名詞為可數(shù)復(fù)數(shù)名詞時，謂語動詞用復(fù)數(shù)形式；of后面的名詞為不可數(shù)名詞時，謂語動詞用單數(shù)形式。試比較：

    Three-fifths of the work is hard to finish.五分之三的工作很難完成。

Three-fifths of the students in our class are League members.我們班五分之三的學(xué)生是共青團員。

注意：數(shù)詞作主語時，謂語動詞多使用單數(shù)形式。如：What’s two and/plus three?

八、考查時間的表達(dá)法

1. 整點鐘：基數(shù)詞+o’clock。

2. 非整點時間：順讀（先說點鐘，再說分鐘）或逆讀：

⑴當(dāng)分鐘數(shù)小于或等于30時，可用“分鐘+past+點鐘”表示。如：7：25 twenty-five past seven

⑵當(dāng)鐘點數(shù)大于30時，可用“（60―分鐘）+to +（點鐘+1）”表示。如：7：35 twenty-five to eight(60―35=25) (7+1=8)

注意：15 minutes = a quarter 30 minutes = half

九、考查特殊短語的表達(dá)

我們需要掌握以下短語的常見表達(dá)：半個小時→half an hour, 一天半→one and a half days或one(a) day and a half, —、二天→one or two days或one day or two, 三、五次→three or five times。

注意：后面兩個短語中的or不可用and代替。
