People are worried about the fact that the number of whales is getting smaller and smaller. Whales have been hunted since about the eleventh century. Certain types of whales have been hunted too much. Recently, their number has been ________ so greatly that they are in danger of becoming extinct. People are working to save the whales.
A.increased
B.added
C.reduced
D.decreased
主要在C、D之间纠结
其实我想说的是，B、C也是反义词。。。

Answer 1

选D
某些场合reduce和decrease可互换，但在词典比较很多例句之后，个人觉得reduce和decrease的主观色彩有略微侧重不同。更多的时候，reduce倾向于主观人为地、有意识地使之减少，decrease侧重于客观减少为多。
例：
reduce one's weight from 98 to 92 kilos/by 6 kilos 把体重从98公斤减少到92公斤[减少6公斤]----主观目的
Student numbers have decreased by 500. 学生人数减少了500名.----客观事实
本题：Certain types of whales have been hunted too much. Recently, their number has been ________ so greatly that ...不宜填reduced，那会显得之前的鲸鱼被捕是人们为了使之数量减少而采取的措施手段了，相比较，decreased较适合，只是说前者人类行为引发了后者的现象这一客观事实。但要非找出与我观点背道而驰的特殊例句也是存在的，这只是一个大多数规律。
（个人观点而已，仅供参考）

Answer 2

选D。

add和reduce是及物动词，其主语往往是人。
increase和decrease是不及物动词。数量本身的增长或减少用这两个词。

Answer 3

选D

"reduce" 是动作发出者使某样事情“减少”，偏主观。例如：He won't reduce the rent of our house.（他不会减少我们的房租）。"decrease" 是动作发出者自身被减少，偏客观。例如：The population began to decrease.（人口开始减少了）。此题是客观情况，是鲸的自身数量减少，故选D。

Answer 4

Reduce是数量程度上的减少，而decrease是逐渐减少有一个渐进过程，所以个人认为应该选C

Answer 5

D 因为AD是反义词 所以.....
