A experiment B occasions
the answer is B,why not use
A experiments 忘记写S了
A experiment B occasions
the answer is B,why not use
A experiments 忘记写S了
其实很简单,看前面的介词就可以分辨出来：
“On an occasion/On one of the occasions” 意思是：在其中的一个场合、一次事件...所以要采纳occasion.
而 experiment 的前面应该是 in,“in an experiment/experiments, we .” 如果要用 on 的话,就要说：We did an experiment on an animal. 不是用 on 作为开头.
而且,在日常用语里头,英语用 occasions 的机会比较多,除非是学术性的形容,那就采取 experiment.
希望帮到你.
