答案:B
解析:考查倍數(shù)被動法,。倍數(shù)表達有四種:1.“A+倍數(shù)+形容詞或副詞的比較級+than+B”,2.“A+倍數(shù)+as+形容詞或副詞的原級+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。
點評:倍數(shù)表達要牢記,,倍數(shù)表達法是高中英語教學(xué)的重點,,也是歷屆高考的熱點。當我們要表達甲是乙的幾倍時,,通常用句型來表示:
1.“A+倍數(shù)+形容詞或副詞的比較級+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+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。
