7.After the new technology was introduced,the factory produced ________ cars in 2010 as the year before.( 。
A.as many twiceB.as twice manyC.twice many asD.twice as many

分析 引進(jìn)新技術(shù)以后,這家工廠在2010年生產(chǎn)的汽車是前一年的兩倍.

解答 答案:D.根據(jù)the factory produced __cars in 2010as the year before,可知工廠在2010年生產(chǎn)的汽車是前一年的兩倍,這里考查了倍數(shù)表達(dá)法:倍數(shù)+as形容詞/副詞原級(jí)as…,倍數(shù)要放在as的前面.本題的many修飾cars.選項(xiàng)ABC都不符合.故選D.

點(diǎn)評(píng) 本題考查了量詞中倍數(shù)表達(dá)法.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: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(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".

2.When you travel around the European countryside,you can be lucky to find an unusual house-a tiny house.
Tiny houses are hand built home structures that are generally from 100to 300square feet(平方英尺),often on wheels.A tiny house is small enough to pull,so you can use a truck(卡車)to haul it around the countryside.If you decide to move to a new place,or just feel it necessary to change your living environment,you can take your house with you because it is easily moveable and convenient.

Tiny houses are for people who don't ask for too much.Besides,tiny houses are for people who are interested in a green lifestyle.
