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 引进新技术以后,这家工厂在2010年生产的汽车是前一年的两倍.

解答 答案:D.根据the factory produced __cars in 2010as the year before,可知工厂在2010年生产的汽车是前一年的两倍,这里考查了倍数表达法:倍数+as形容词/副词原级as…,倍数要放在as的前面.本题的many修饰cars.选项ABC都不符合.故选D.

点评 本题考查了量词中倍数表达法.当我们要表达甲是乙的几倍时,通常用句型来表示:1."A+倍数+形容词或副词的比较级+than+B",表示"A比B大(长、高、宽等)多少倍".2."A+倍数+as+形容词或副词的原级+as+B",表示"A正好是B的多少倍". 3."A+倍数+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(卡车)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 built from green building materials.They are quite suitable for a single person or couple who have a strong wish to live simply.Some tiny houses are designed more like Victorian(维多利亚女王时代的)country houses with very simple small windows and halls.Others are simpler structures-comfortable but cute structures with folding furniture The small houses need fewer materials to build and they use less energy.But many tiny house builders create a separate bath house nearby to leave more living space and create private space for bathing and personal care.
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.
