OG 2016 Verbal 38 关于their和less than的问题

阿霖

Around 1900, fishermen in the Chesapeake Bay area landed more than seventeen
million pounds of shad in a single year, but by 1920, overfishing and the
proliferation of milldams and culverts that have blocked shad migrations up their
spawning streams had reduced landings to less than four million pounds.
(A) that have blocked shad migrations up their spawning streams had
reduced landings to less
(B) that blocked shad from migrating up their spawning streams had
reduced landings to less
(C) that blocked shad from migrating up their spawning streams reduced
landings to a lower amount
(D) having blocked shad from migrating up their spawning streams reduced
landings to less
(E) having blocked shad migrations up their spawning streams had reduced
landings to an amount lower

正确答案是B
在B中their指代shad，说明这里的shad是复数
但后面又说had reduced landings to less than...如果这里的landings也指shad的话，为何是less而不是fewer呢？OG的解释说，the fishermen landed different amounts of fish，但这边的fish--shad不是复数么？并且landings本身有s，看起来也很像是复数。

该题中landings本身是一个单数名词，意思是“登陆量”。把langdings当成一个数字来比较，用less than。

好的，谢谢。不过landings好像是捕鱼量的意思？因为我看land有捕鱼的意思额。

是的，捕鱼量这个词义更好
