D 该题表示倍数的用法。表示倍数的句型：倍数+比较级+than倍数+ 同级比较（as/so+形容词/副词的原级（名词）+as倍数+the size(length, weight) of。据此应选B。句意：据报道美国所消耗的能源是欧洲所消耗总和的两倍。3.D 考查倍数的表达方式，在表达倍数时，倍数都应位于原级或比较级之前，因此D正确。4.D 该题考查数词的用法。数词one-third要放在名词前面，而名词time后面有定语从句it took me，故为特指，应当在他前面加定冠词the。因此，答案为D。题意：他做这件事用了我用时的三分之一。5C该题考查数词与主谓一致的用法。分数的表达式“基数词+序数词的复数”；land为不可数名词，故谓语动词用单数。句意：该地区五分之二的土地为草和森林所覆盖。6. D该题考查数词的用法。在几十年代，在数词复数前加定冠词，即in the 90s；在某人多少多岁时，是在数词复数前加形容词性的物主代词，即：in ones fifties。句意：九十年代人们五十多岁时上大学深造并不稀罕。7. D该题考查数词的用法。序数词前加定冠词。乔治在他一生中所发现的第一百个洞穴是在阿尔卑斯山附近。8.

eight在变为eighth时少了一个字母t；nine在变为ninth时去掉了一个字母“e”; 以“ve”结尾的基数词变序数词时，须将“ve”改为“f”，然后再加“th”。fivefifth，twelvetwelfth20,30, - 90 各十位数字变y为i后加thtwentytwentieth，thirtythirtiethsixty-ninesixty-ninth21-29313991-99只须变个位的基数词为序数词twenty-twtwenty-secondforty-fourforty-fourthsixty-ninesixty-ninth1.序数词前不用定冠词的情况1)表示顺序的语气很弱，具有“又一”、“再一”的意思时，其前要用不定冠词，不用定冠词。如:l.He cast the net a second time.2.A third bullet passed.2)序数词前己有指示代词、物主代词、名词所有格或every时，不用定冠词。如:l.He made his first set in an old box.2.Berlin in 1929 held a public celebration on Einsteins fiftieth birthday.3)在表示分数的序数词前不用定冠词。如:From then on Bashi toured three-fourths of Beijing.Two-thirds of the area is covered by trees.4)数词与名词构成复合名词时，不用定冠词。如:There is a first-class hotel over there.He went to a second-hand bookshop.5)序数词用作副词时，不用定冠词。如：Why did the captain first hesitate in letting the boy risk climbing the tree?First come，first served.6)在一些由序数词构成的固定词组里不用定冠词。如:1.at first 2.first of al1 3.from first to last三、数词的功能1表小数、分数和百分数1.小数点读作point,零读zero或nought。小数点后的数字按个位基数词依次读出。如：3.4three point four,0.2zero(nought)point two,0.03zero point zero three,3.458three point four five eight2.百分数由基数词后直接加percent(per cent)构成。如:20%2Opercent(per cent) 3.分数由基数词 (分子)和序数词 (分母)合成。分子大于l时，表分母的序数词要用复数形式。如: 1/3one/a third 2/3two thirds但1/2一般用a/one half;1/4用a/one quarter或one fourth。3.表示几分之几 (或百分之几)的人或物时，须在分数 (或百分数)和人或物间加of。若充当主语，谓语动词的数须与of后的名词的数保持一致。如:One third of the students are girls.1/3的学生是女生。Sixty percent of her income was spent on clothes.她收入的60%花在了服装上。但当表示人口的几分之几 (或百分之几)作主语时，谓语动词常用复数形式。如:The population in China is very large, and eighty percent of it are farmers.中国的人口众多，其中80%是农民。2表加减乘除1.加法的表达法如表达“几加几是多少”，可用“What/How much is+基数词and/plus+基数词？”；如表达“几加几等于几”，可用“基数词and+基数词is基数词”。如：What/How much is seven and eight?7加8是多少？Seven and eight is fifiteen. 7加8等于15。2减法的表达法如表达“几减几是多少”，可用“What/How much is+基数词minus+基数词？”；如表达“几减几等于几”，可用“基数词minus+基数词is基数词”。3.乘法的表达法如表达“几乘几是多少”，可用“What/How much is+基数词times+基数词？”；如表达“几乘几等于几”，可用“基数词times+基数词is基数词”。4.除法的表达法如表达“几除以几是多少”，可用“What/How much is+基数词divided by+基数词？”；如表达“几除以几等于几”，可用“基数词divided by+基数词is基数词”。3表时间1.用数字表达法来表示几点几分时，分钟数在后，并且不可使用quarter, half。如：8:15 eight fifteen(不能说：eight a quarter)10:30 ten thirty(不能说：ten half)2.使用介词past表示“几点过几分”，用to表示“几点差几分”时，分钟数放在介词前。11:25 twenty-five past eleven(=eleven twenty-five)6:40 twenty to seven(=six forty)3.past,to前的分钟应小于三十分钟（如果正好是三十分，应用half）。如：5:55 five to six=five fifty-five(不能说：fifty-five past five)5:30 half past five=five thirty(不能说：thirty past five或five half)4数词用于编号表示编号，可以用基数词，也可以用序数词，即:事物名词(不加冠词)+基数词;the+序数词十事物名词。如:Lesson Twelve=the Twelfth Lesson 第十二课Part Onethe First Part第一部分World War I=the First World War第一次世界大战如英语编号中数字较长，一般用基数词表示。如:Room 506 第五0六号房间 page 265 第二百六十五页Telephone NO.8297976 电话号码82979765表倍数两倍：twice 两倍以上：基数词+timesThis classroom is twice as big as that one.The house is three times bigger than that one四、数量名词的单复数形式1. hundred，thousand，million的用法当前面有数词以及many，several等词修饰时，这三个词用单数形式，后面直接跟复数名词。当这几个词前面没有数词而后面有of时，则一定要用复数形式，表示数百、 数千等笼统的数目概念。如:two hundred students 200名学生several thousand enemies 几千敌人hundreds of dollars 数百美元millions of ants 数百万蚂蚁2. score(二十)，dozen (打; 十二个)的用法1)当dozen与基数词或many,several等连用时，不加“-s”，所修饰的名词前常省去of。但是，在a dozen of these people, two dozen of them等短语中应加of。这是因为习惯上在these, those, us等词前该用dozen of的缘故。 two dozen books 两打书 two (many,several)dozen pencils 两打（几打）铅笔some dozen people是“若干打的人（几十个人，许多人）”。2) score意为“二十”。two score of people中应加of，但three score and ten people，“70人”中不加of。scores of people意为“许多人”。上述这两个词的复数形式与of连用时，表示不确切的数量，意为许多，大量的。如:for dozens of years 好几十年以来scores of years ago 许多年前scores of times 许多次第三节 巩固提高1.-Have you seen_workers pass by? -Yes，Ive seen_them.A. woman;
