Unit 1 Living with technology單元復習學案

a.as much twice as　b.twice as much as
c.much as twice as    d.as twice much as
解析：選b。考查倍數表達法。b項為固定的倍數表達法，即“倍數＋as＋adj./adv.＋as＋比較對象”結構。
21.(XX年高考四川卷)my uncle’s house in the downtown area is much smaller than ours，but it is twice________expensive.
a.as   b.so
c.too   d.very
解析：選a。考查倍數句型及其省略。這里是倍數句型：倍數＋as＋adj./adv.＋as。這里省略了as ours。
22.ten years ago the population of our village was________that of theirs.
a.as twice large as   b.twice as large as
c.twice as much as  d.as twice much as
解析：選b。考查倍數表達法。倍數句型主要有以下三種：
(1)a is...times as＋adj.＋as b；
(2)a is...times the size/length/width/height/depth，etc.＋of b；
(3)a is...times＋adj.比較級＋than b；
由題干可知本題是第一種句型，又由于population應用large修飾，而不能用much修飾。
23.i collected________he did for the hope project the day before yesterday.
a.three times as many money as
b.three times much money than
c.three times more money than
d.three times much more money
解析：選c。考查倍數的用法。語意：前天我給希望工程募集的錢比他的多三倍。這里用倍數＋more＋名詞＋than句型，這里more是much的比較級，修飾不可數名詞money。
24.a study of more than 18,000 chinese men suggests that green tea drinkers are________to develop stomach cancer as those who drink little or no tea.
a.half as likely      b.likely half as
c.likely as half      d.as half likely
解析：選a。考查倍數表達法。表示事物對比時，可用“倍數＋as＋形容詞/副詞原級＋as＋比較對象”。只有a項正確。
