243.some scientists have been critical of the lab tests conducted by the FDA on the grounds that the amounts of suspected carcinogens fed to animals far exceeds those that humans could consume.
(A)far exceeds those that humans could consume
(E)far exceed those that humans could consume
查了一下字典amount:a number of things...many people consider this use to be incorrect...所以看來是可以接複數N.可是很多人覺得這樣用是錯的....我想問的是問什麼這裡不用a/the number of suspected carcinogens而寫成the amounts of suspected carcinogens...thx
