In the 1820's physical education became ___of the curriculum of Harvard and Yale Universities.
(A) to be part
(B) which was part
(C) was part
(D) part
The answer is (D)
這題我是有答對啦!! 但是我想請問一下, 因為我本來是想說應該要parts或是a part才好, 但後來查字典, 發現當part作"部分"解釋時, 可作U或是 c, 那我想要請問, 什麼時候part應該用可數形式, 而何時又該使用不可數行式呢? 或是其實都是隨便人用的?
Thanks
