典型例题
1)The weather in China is different from____.
A. in America B. one in America C. America
D. that in America
答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C不能选。A没有名词，后句成分不全，排除。B和D中，B中的one常用来代替可数名词，而that可车以代替不可数或抽象名词，所以选D.
2)After the new technique was introduced，the factory produced ___ tractors in 1988 as the year before.
A. as twice many B. as many twice C. twice as many D. twice many as
答案C. 此句意为"这个厂1988能生产的拖拉机是往年的两倍".表示倍数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为C.
