答案:B
解析:考查倍數(shù)被動(dòng)法,。倍數(shù)表達(dá)有四種:1.“A+倍數(shù)+形容詞或副詞的比較級(jí)+than+B”,2.“A+倍數(shù)+as+形容詞或副詞的原級(jí)+as+B”,,3.“A+倍數(shù)+the size/height/length/width,,etc+of+B”,4.“……times+what+從句”,。本題使用的是第3種,。句意:新的電腦要花的錢是二手電腦的三倍。故B正確,。
點(diǎn)評(píng):倍數(shù)表達(dá)要牢記,,倍數(shù)表達(dá)法是高中英語教學(xué)的重點(diǎn),也是歷屆高考的熱點(diǎn),。當(dāng)我們要表達(dá)甲是乙的幾倍時(shí),,通常用句型來表示:
1.“A+倍數(shù)+形容詞或副詞的比較級(jí)+than+B”,表示“A比B大(長,、高,、寬等)多少倍”。如:
This rope is twice longer than that one.這根繩子是那根繩子的兩倍長(比那根繩子長一倍),。
2.“A+倍數(shù)+as+形容詞或副詞的原級(jí)+as+B”,,表示“A正好是B的多少倍”。如:
Asia is four times as large as Europe.亞洲的面積是歐洲的四倍,。
3.“A+倍數(shù)+the size/height/length/width,,etc+of+B”,,表示“A正好是B的多少倍”。如:
This street is four times the length of that one.這條街是那條街的四倍長,。
4.“……times+what+從句”,。如:
The production is now three times what it was ten years ago.現(xiàn)在的產(chǎn)量比十年前增加了兩倍。
