試題分析:考查倍數(shù)表達(dá)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”。所有四種方法中都把倍數(shù)放在了最前面,本題中的half就是倍數(shù)。考查了2種倍數(shù)的表達(dá)形式。經(jīng)驗(yàn):信不信由你,我們加還沒有上個(gè)月他們買的新房子的一半大。故A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)+形容詞或副詞比較級(jí)+than+B”,表示“A比B大(長、高、寬等)多少倍”
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。
