有大哥大姐会这道题么
At the computer operation test,one is supposed to stay at his own machine,keep his eyes on his screen,___to anyone.
A.and not to speak B.but could not speak
C.instead of speaking D.or rather speak

B项如果没有这个could也可以：is supposed to do A,do B ,but not do C.
D项凑数项,不用考虑.
C项有很大的干扰性.instead of doing sth.而不是.
但是,前面要用and ：is supposed to do A and do B instead of doing C.
