答案选B
look 是不及物动词,后面不能直接接宾语,必须加介词at,才能接宾语,而see是及物动词,后面可以接宾语,而且look at 指看的动作,而see指看的结果.这句话的意思是：看黑板,你能看到它吗?显然前一句指看的动作,用look at,后一句指看的结果,用see,所以选B.
_ the blackboard.Can you _ it?A.Look；see B.Look at;see.C.See;look D.See;look at.
_ the blackboard.Can you _ it?A.Look；see B.Look at;see.C.See;look D.See;look at.
