<strong>答案解析
<strong>1．C
<strong>【解析】
<strong>試題分析：句意為：九月是一年的第九個月。通常，序數詞是在基數詞的基礎上加th構成。但是有些詞也例外。如：one-first,two-second,three-third,five-fifth,eight-eighth,nine-ninth等，故選C。
<strong>2．D
<strong>【解析】
<strong>試題分析：句意為：一年中有12個月，九月是第九個月。基數詞表示數量，序數詞表示順序。結合語境，第一個空應應基數詞，第二個空應用序數詞，“第九”應該是ninth。故選D。
<strong>3．B
<strong>【解析】
<strong>試題分析：句意：中國人已經使用紙兩千多年了。thousand表示確切數字時，不用複數形式，也不與of連用；但表示概數時，必須使用複數形式，而且要與of連用。所以選B。
<strong>4．D
<strong>【解析】
<strong>試題分析：句意：我看到教室裡有十二個孩子，五個男孩，七個女孩。nine九，thirteen 十三，eleven十一，twelve十二。根據題意，故選D。
<strong>5．B
<strong>【解析】
<strong>試題分析：句意：建設科學實驗室花費多少錢？五百萬元。Million百萬；在具體的數字裡不用複數形式，如three million；但在短語millions of數百萬，要用複數形式；故選B。
<strong>6．B
<strong>【解析】
<strong>試題分析：句意：這個國家的三分之二被雪所覆蓋。在英語中分子用基數詞表達，分母用序數詞表達如果分子大於1，分母變複數。分數作主語時，根據其後接的詞而定，如果為不可數名詞或名詞的單數，則相當於單數，如果其後接的為可數名詞複數形式，則相當於複數，故選B
<strong>7．A
<strong>【解析】試題分析：句意:上個月三分之二還要多的孩子參加了活動。本題考查分數的表達，分子應該用基數詞，分母用序數詞。分子大於一的時候，分母用複數。two thirds 三分之二，是分數的正確的表達方式；B、C和D形式都不對。故選A。
<strong>8．B
<strong>【解析】
<strong>試題分析：句意幾乎地球表面的四分之三被海洋覆蓋。分數的表達方式：分子用基數詞，分母用序數詞，當分子超過一了，分母變複數，本題中把地球看做整體，所以謂語動詞用單數，故選B。
<strong>9．A
<strong>【解析】此題重點考查定語從句的引導詞和序數詞的用法。先行詞The boy 在從句中充當主語，引導詞可以用who也可用that。某人的第幾生日要用序數詞。
<strong>10．C
<strong>【解析】
<strong>試題分析：句意：成千上萬棵樹被砍伐。許多鳥類失去了他們的家。在表示確切數字時，thousand不用複數，也不與of連用，但表示概數時，thousand必須使用複數形式，並且與of連用。所以選C。
<strong>11．A
<strong>【解析】試題分析：句意:網絡上三分之二的新聞報道是用英語寫的。英語中分數的構成，分子用基數詞，分母用序數詞，當分子大於一的時候，分母加s，故排除C和D；當分數修飾名詞做主語的時候，謂語動詞的單複數形式應該跟分數所修飾的名詞保持一致。在這個句子中news reports是複數的形式，故動詞也用複數，所以選A。
<strong>12．A
<strong>【解析】分數在英語中通常是藉助於基數詞和序數詞來共同表達的。其中基數詞表示分子，序數詞表示分母。分子超過1，分母要加s.分數修飾名詞時，若該名詞是不可數名詞只能用單數；若是可數名詞，用單數或複數均可。但是，若它們在句子中作主語，則謂語動詞是用單數還是複數取決於名詞，即與分數所修飾的名詞保持一致。
<strong>13．C
<strong>【解析】
<strong>試題分析：句意：米歇爾和她的朋友在三月二十一日到達了北京。她開始了七天的中國觀光。分析：七天的，有兩種表示方法1.名詞所有格形式，seven days’. 2. 數字與單位加連字符的形式，seven—day.結合選項只能選擇第三項。故選C
<strong>14．C
<strong>【解析】
<strong>試題分析：句意為：他們學校學生的數量大約2000人。其中2/3是男孩。the number of+名詞複數，指“……的數量”，a number of+名詞複數，表示“許多的”“大量的”。分數的表達：分子用基數詞，分母用序數詞，當分子大於1時，序數詞加“s”。結合選項可知應選C。
<strong>15．D
<strong>【解析】
<strong>試題分析：句意：三分之二的水被汙染了。我們必須保護我們的環境。在英語中分子用基數詞表達，分母用序數詞表達如果分子大於1，分母變複數。分數作主語時，根據其後接的詞而定，如果為不可數名詞，則相當於單數，如果其後接的為可數名詞複數形式，則相當於複數。根據句意，故選D。
<strong>16．D
<strong>【解析】
<strong>試題分析：句意：學生的五分之三將參加運動會。在英語中分子用基數詞表達，分母用序數詞表達如果分子大於1，分母變複數。根據句意，故選D
<strong>17．A
<strong>【解析】試題分析：在英語中 姓和名、年級、班級、序號等的首字母要大寫。故排除BD.C選項序數詞前應加the，序數詞第三的縮寫為the 3rd。故選A.Year 3="the" 3rd Year三年級。
<strong>考點：考查數詞及名詞的用法。
<strong>18．C
<strong>【解析】hundred前無論是數字多少，hundred後都不加s，而hundreds of表示成千上萬，前面一般不加數詞，但是數詞+hundred of +the n（C）複數形式，故選答案為C
