In 1914 a total of 469,000 cars and trucks were produced in the United States, but in 1929 almost twice the numbers of tucks alone came off the assembly lines.
According to surveys by the National Institute on Drug Abuse, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey.
(A) doubling those reported in the 1977 survey
(B) to double the number the 1977 survey reported
(C) twice those the 1977 survey reported
(D) twice as much as those reported in the 1977 survey
twice作为副词只能修饰动词或形容词,如果你注意的话会发现,在我们看到的绝大多数twice + n. 的结构中,这个短语本身都不是一个完整的句子,其实,这个短语绝大多数都是句子的简略;而twice作为标准句子的表达通常如下:Interest rates of our company are twice as high as those of our competitiors. 我们可以把这个句子改为:Interest rate of our company is 5%, twice as high as that of our competitors. 当然句子改的很不爽,但是可以区别出彼此的关系。
从语法上讲,twice不能修饰名词,而从逻辑上讲,我觉得twice只能修饰名词the number呢.例如:Twice two is four.这里,twice修饰谁呢?修饰is吗?
再如GWD:
In 1914 a total of 469,000 cars and trucks were produced in the United States, but in 1929 almost twice the numbers of tucks alone came off the assembly lines.
the numbers of tucks alone
that number of trucks alone
the number of trucks by themselves
as many trucks themselves
as many trucks by themselves
答案选B. but后是个完整句子, in 1929 almost twice that number of trucks alone came off the assembly lines. 这里twice又修饰谁呢? that number不是吗? 可是twice是副词,怎么能修饰that number 呢? 可是要理解成twice理解后面的came off好象很难呀......
还有就是这题大全51, twice the number reported in the 1977 survey.这里twice不是修饰the number吗?
