考點(diǎn)3 考查用英語(yǔ)表示分?jǐn)?shù)的用法 用英語(yǔ)表示分?jǐn)?shù)的方法是:先說(shuō)分子,后說(shuō)分母;分子用基數(shù)詞,分母用序數(shù)詞;當(dāng)分子超過(guò)“一”時(shí),分母用復(fù)數(shù)形式。如“三分之二”可表示為 two thirds (可理解為“兩個(gè)三分之一”)。但是有些分?jǐn)?shù)的表示比較其特別,如“二分之一”通常說(shuō)成a (one) half,“四分之一”通常說(shuō)成 a quarter。 【考例】________ of the students in our class ________ money to the disabled people these days. (貴州安順中考題) A. Two third, have raised B. Two thirds, has raised C. Two three, have raised D. Two thirds, have raised 【分析】答案選D。“三分之二”的分子是“二”,用基數(shù)詞two表示;分母是“三”,用序數(shù)詞third表示,由于分子大于一,故表示分母的third要用復(fù)數(shù),即可排除A和C;又因?yàn)橐粋(gè)班三分之二的學(xué)生肯定不只一個(gè),故謂語(yǔ)動(dòng)詞要用復(fù)數(shù),即選D不選B。 考點(diǎn)4 考查hundred, thousand, million單復(fù)數(shù)用法 當(dāng)hundred, thousand, million與數(shù)詞連用表示具體數(shù)量時(shí),它們既不用復(fù)數(shù)形式,后接名詞時(shí)也不用介詞of。如: Can you lend me a hundred dollars? 你可否借給我一百美金? This theatre holds a thousand persons. 這家劇院能容納一千人。 The sun is 92 million miles away. 太陽(yáng)離這里有九千二百萬(wàn)英里。 但是,若泛指數(shù)百、數(shù)千、數(shù)百萬(wàn)等,則用 hundreds of, thousands of, millions of 等這樣的結(jié)構(gòu)。如: Hundreds of people attended the meeting. 有幾百人參加了會(huì)議。 They received millions of letters asking for information. 他們收到了無(wú)數(shù)的咨詢信件。 Men have been making music for thousands of years. 人類創(chuàng)作音樂(lè)已有數(shù)千年歷史。 【考例1】More than two ________ years ago, people knew little about the universe. (遼寧錦州中考題) A. thousands B. thousand C. thousand of D. thousands of 【分析】答案選B。與具體數(shù)字連用時(shí),thousand不用加詞尾-s,其后也不用介詞of。 【考例2】Enshi is becoming a tourist city. ________ people come here during the holidays every year. (湖北恩施中考題) A. Thousand of B. Thousands of C. Five thousands of D. Five thousands 【分析】答案選B。與具體數(shù)字連用時(shí),thousand不用加詞尾-s,其后也不用介詞of,故可排除C和D。但表示不確定的“數(shù)千”“數(shù)以千計(jì)”時(shí),則不僅要加詞尾-s,而且要后接介詞of,故只能選B,不能選A。 考點(diǎn)5 考查帶有數(shù)詞的復(fù)合形容詞中名詞的數(shù) 根據(jù)英語(yǔ)習(xí)慣,在“數(shù)詞+名詞”“數(shù)詞+名詞+名詞”“數(shù)詞+名詞+形容詞”這類復(fù)合形容詞中,其中的名詞只用單數(shù)形式,不用復(fù)數(shù)形式。如: a two-mile walk兩英里的步行 a six-inch ruler六英寸長(zhǎng)的尺子 a two-hour exam. 一次兩小時(shí)的考試 a five-day week 一周五個(gè)工作日 a five-year-old boy 一個(gè)五歲的男孩 an eighteen-month-old baby 一個(gè)18個(gè)月大的嬰兒 a five-hundred-meter rope 一根 【考例1】Each of us has to write a ________ report every two weeks. (廣州中考題) A. two-hundred-word B. two-hundreds-word C. two-hundreds-words D. two-hundred-words 【分析】答案選A。帶有數(shù)詞的復(fù)合形容詞中,數(shù)詞后的名詞要用單數(shù)。又如:She has a ten-year-old son. 她有個(gè)10歲的兒子。He wrote a five-hundred-word letter to me. 他給寫了一封500字的信給我。 【考例2】A new study proves a ________ walk every day is enough to keep people away from becoming fat. (哈爾濱中考題) A. 30-minute B. 30 minute’s C. 30-minutes D. 30 minute 【分析】答案選A。按英語(yǔ)習(xí)慣,在帶有數(shù)詞的復(fù)合形容詞中,數(shù)詞后的名詞要用單數(shù),所以不能選C;另外,這類結(jié)構(gòu)中的連字符原則上不能省略。 |
