1、精選優質文檔-傾情為你奉上中考英語數詞考點歸納與例析【重點講解】數詞分為基數詞和序數詞兩種，表示事物數目的詞稱為基數詞如one, two, three, forty等；表示事物順序的數詞稱為序數詞。如first, second, third, fortieth等。數詞的用法要注意一下幾點： 1、基數詞和序數詞的拼寫形式。主要掌握1-12及20、21等的序數詞的形式，其它序數詞都是在基數詞末尾加-th，是有規律可循的。onefirstsixsixtheleveneleventhtwosecondsevenseventhtwelvetwelfththreethirdeighteighththirt

2、eenthirteenthfourfourthnineninthtwentytwentiethfivefifthtententhtwenty-onetwenty-first另外，序數詞的縮略形式是由阿拉伯數字加序數詞的最后兩個字母構成。例如：1st, 25th。2. 時刻表達法。表示時刻有兩種說法： 1) 先說分鐘，后說鐘點。幾點過幾分，分鐘不超過三十分鐘時用past。例如：Its five past eight now. 現在是八點（過）五分。幾點差幾分或差幾分幾點，差的分鐘數不超過二十九分鐘時,用to。例如：Its twenty-nine to eight. 八點差二十九分。Its a q

3、uarter to eight. 差一刻八點。2)先說鐘點，后說分鐘。在日常生活中，為了簡便，常用這種說法。例如：Its eight thirty. 八點三十分。3年、月、日表達法。 1）年份用基數詞表示，一般寫為阿拉伯數字，讀時可以以hundred為單位，也可以以世紀、年代為單位分別來讀。如：1949 讀作 nineteen hundred and forty-nine 或 nineteen forty-nine；2000讀作twenty hundred，或two thousand。表示在哪一年，一般在年份前加介詞in，使用year時，year放在數詞之前。如：in the year two

4、 fifty-three B.C. 在公元前253年。但是，通常采用in加表示年份的阿拉伯數字。2）在哪個月用介詞in加月份詞表示。例如：in May在五月。3）日期用定冠詞the加序數詞表示。在哪一天要用介詞on。例如：National Day is on Oct. 1. (=National Day is on the 1st of October) 國慶節是十月一日。 4）美國英語的月份在日期前面, 如：2008年8月3日表達為August 3, 2008；英國英語的習慣是日在月前, 如：3 August 2008或3rd August 2008.4電話號碼及編號。編號既可以用序數詞，也

5、可用基數詞。例如： the first lesson - Lesson One 第一課the fiftieth page - page 50第五十頁 有的編號習慣上常用基數詞。例如： Room 829 (讀作eight two nine) 829號房間 Tel. No. (讀作Telephone number two seven nine three five eight six) 5分數的表達法。分數由基數詞和序數詞合成。分子用基數詞，分母用序數詞。分子是1 時，分母用單數形式；分子大于1時，分母用復數形式。例如：1/3 one third；2/3 two thirds6小數的表達

6、法。整數與小數之間用小數點隔開。讀小數時，每位數字(特別是小數點后面的)要單獨讀出。小數點讀作point (點)，零讀作zero (或naught)。如果整數是零，往往不讀出。例如： 0.5讀作zero(naught)point five, 或point five 7. 百分數的表達法。5% 5 per cent讀作：five percent8. 加減乘除表示法。1） “加”用plus，and或add表示；“等于”用is，make，equal等詞表示。1+2=? 可表示為：How much is one plus two?If we add one to/and two, we ge

7、t three一加二等于三。2）“減”用 minus表示。106? How much is ten minus six?Take six from ten and the remainder is four. 十減去六等于四。3） “乘”用time（動詞）或multiply表示。3X7? How much is three times seven?Three multiplied by seven makes twenty-one三乘以七等于二十一。4） “除”用divide的過去分詞形式表示。12 ÷ 4=? How much is twelve divided by four?T

8、welve divided by four equals/gives/makes three十二除以四等于三。【中考鏈接】1. - Do you still remember the snow storm last winter？- Sure! _ people _ from going home during that time.A. One hundred, stopped B. Ten hundreds of, were stopped C. Hundreds, stopped D. Hundreds of, were stopped 答案：D。【解析】基數詞表示具體數目時，hundre

9、d, thousand, million用單數形式。但在表示“數百”、“數千”、“數百萬”等不確切數目時，hundred, thousand, million要用復數形式，且后接“of +名詞復數”，所以第一空填Hundreds of；人們是受到暴風雪的阻擋而回不了家，people與stop是被動關系，所以第二空填were stopped。2. - Peter, how old is your father this year?- _. And we just had a party for his _ birthday last weekend.A. Fortieth, forty B. F

10、orty, forty C. Forty, fortieth D. Fortieth, fortieth 答案：C。【解析】該題考查的是基數詞與序數詞的用法。回答年齡，要用基數詞；說“第幾個”生日要用序數詞。3.

11、re there in your class?- Fifty. Two-thirds of us _ from Guangdong.A. isB. comesC. arewD. coming 答案：C。【解析】本題考點是數詞作主語時的主謂一致問題。句中Two thirds of us指“我們當中三分之二的人 ”至少也有幾個人，顯然是復數，因此選C。 5. - How old is the baby? - He is _. A. six-months-old B. six-month-old C. six-months old D. six months old 答案：D。【解析】選項A和C本身

12、是錯誤的，其中的month不可以用復數形式。選項B是“基數詞 + 名詞 + 形容詞”構成的復合形容詞，只能用作定語。6. _ is said that _ tourists visit Geyuan Garden every day.A. That, thousands of B. It, five thousand of C. It , thousands of D. This, three thousand 答案：C。【解析】 “it is said that”，表示“據說”，是一個固定句型。thousand與of連用要用復數形式，所以排除B而選C。7. Time is not enoug

13、h for so much work. _ people are needed, I think. A. Other two B. Only two C. Two more D. Two others 答案：C。【解析】基數詞與more連用，并放在more前，表示“另外有”、“還有”的意思。8. Both of the two rulers are broken.
