試題分析:考查倍數(shù)表達(dá)法。倍數(shù)表達(dá)法:倍數(shù)+as形容詞/副詞原級(jí)as…倍數(shù)一直放在as的前面。本題的many修飾cars。句意:在新的技術(shù)被引進(jìn)以后,2010年這家工廠(chǎng)生產(chǎn)的汽車(chē)是以前的2倍。故D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(yǔ)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(lái)表示: “A+倍數(shù)+形容詞或副詞的比較級(jí)+than+B”,表示“A比B大(長(zhǎng)、高、寬等)多少倍”。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”。 3. “A+倍數(shù)+the size /height /length /width,+of+B”,表示“A正好是B的多少倍”。4.“……times+what+從句”。
