我觉得这里ratio是42 times的同位语,是逗号加同位语跳跃修饰情况。
不过如果前面的成分比较短,不会引起歧义,这个同位语还是可以跳跃修饰的,比如这个例子:
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
(E) twice the number reported in the 1977 survey
OA:E。其中twice跳跃used cocaine修饰20 percent of young adults.
